Title: Oil-in-water emulsion comprising a particular mixture of surfactants and the combination of at least one starch grafted with an acrylic polymer and of at least one starch not grafted with an acrylic polymer

[0001] The present invention relates to a cosmetic composition, in particular of the type oil-in water emulsion stabilized by a particular mixture of surfactants, and comprising the combination of at least one starch grafted with am, in particular superabsorbent, acrylic polymer and of at least one starch not grafted with an acrylic polymer, preferentially a native starch.

[0002] Another subject of the invention is a noil-therapeutic process for the cosmetic treatment of a keratin material, in particular the skin and/or the hair, and more particularly the skin, comprising a step of applying to said keratin material at least one layer of said cosmetic composition.

[0003] A further subject of the invention is the use of said above-mentioned combination of two types of starch for improving, i.e. increasing, the consistency of a cosmetic composition, in particular the sensation of thickness under the finger on application, while providing a powdery, non-tacky, skin finish once the composition has been applied to the skin.

Technical field

[0007] The field of cosmetics formulation is undergoing rapid change. Consumers possess greater environmental awareness, expectations of greater use of natural products, the need to be reassured regarding ingredients in cosmetic formulations, and in particular regarding their harmlessness, their low environmental footprint, their origin, or else their renewable nature. Cosmetics research is therefore striving to provide formulations satisfying to the greatest possible extent this quest in search of environmental responsibility, of more frugal, responsible consumption, of cosmetic products that are both simple and high quality. Consumers desire both "useful" products which make a difference and a simplification of beauty routines, which may rely on age-old knowledge passed down through the generations.

[0008] Innovating for textures employing more biodegradable raw materials, having the smallest possible environmental impact, has become a priority for formulators, while still paying attention to the sensory experience of consumers, the textures obtained must continue to satisfy and the beauty products must continue to remain a source of comfort, of pleasure and lightness.

[0009] In recent years, replacing the synthetic particulate fillers in cosmetic formulations has become a major challenge. Some fillers have a spherical form, with a size within the range from 25 to 50 pm, and are used for the texture and the particular feel that they provide in particular to care creams in jars: a greater thickness under the finger at the start of application, like a cushion, which then leaves behind a soft, powdery and non-greasy film on the skin, characterizing the "skin finish" after application.

[0010] Here, the formulator must respond to a two-fold challenge: on the one hand of naturalness, in which the synthetic polymer fillers and thickeners are replaced by more natural raw materials, or those of a more natural origin; and on the other hand of sensory quality, so that the more natural formulations have the same sensorial properties as the existing less natural formulations they are intended to replace, consumers being in particular used to certain sensorial properties and textures, for example the characteristics of silicones and synthetic polymer fillers.

[0011] The term "natural compound" is understood to mean a compound that is obtained directly from the earth or the soil, or from pkints or animals, via, where appropriate, one or more physical processes, for instance milling, refining, distillation, purification or filtration.

[0012] Compounds "of natural origin" are understood to mean a natural compound that has undergone one or more additional chemical or industrial treatments, giving rise to modifications that do not affect the essential qualities of this compound and/or a compound predominantly comprising natural constituents that may or may not have undergone transformations as indicated above. [0013] As non-limiting examples of additional chemical and industrial treatments giving rise to modifications which do not affect the essential qualities of a natural compound, mention may be made of those permitted by the regulatory bodies, such as Ecocert (Reference system for biological and ecological cosmetic products, January 2003), or defined in recognized handbooks in the field, such as Cosmetics and Toiletries Magazine , 2005, volume 120, 9:10.

[0014] The replacement of certain synthetic ingredients in a formulation, by more natural ingredients, can lead to problems of change in texture, and stability problems, and can in turn require adaptations in terms of the other ingredients of the formulation to be revamped, in order to return to the initial texture and sensory quality that consumers are used to for formulations of this type.

[0015] It is thus sought to formulate compositions comprising ingredients which are compatible with the formulation of more "natural" cosmetic products and which have good cosmetic properties, while being stable.

[0016] An objective of the present invention is therefore that of providing a composition of oil- in-water emulsion type, which is of sufficient consistency to have good in-jar hold, an appreciable thickness under the finger at the start of application, and which has good sensorial properties such as the absence of greasy or tacky sensation during and after application.

[0017] An objective of the present invention is also to provide a composition, in particular of oil-in-water (O/W) emulsion type, based on ingredients that are as natural as possible.

[0001] [0018] The applicant has now found that the combination of at least one starch grafted with an acrylic polymer, in particular in the form of a superabsorbent polymer at least partially based on starch, and of at least one starch, in particular native starch, in an oil-in-water emulsion stabilised by a particular mixture of surfactaints, especially combining fatty acid ester of polyethylene glycol and C16-C22 fatty acid ester of sorbitan, makes it possible to obtain a more natural composition with a characteristic texture, exhibiting both good in-jar hold or consistency and good in-jar stability, an appreciable thickness under the finger on application and a non-tacky skin finish.

[0019] This combination of at least two particular starches, preferably native starch and starch grafted with an acrylic polymer, makes it possible to obtain emulsions having an appearance, a sensory quality, a texture, a consistency and in particular a finger take-up, that are comparable to those obtained with polymeric particulate filters of wholly synthetic origin.

Detailed description [0020] A subject of the present invention is thus a cosmetic composition in the form of an oil- in- water emulsion comprising: a) at least one continuous aqueous phase, b) at least one oily phase dispersed in said aqueous phase, c) at least one emulsifying system comprising: i- at least one fatty acid ester of polyethylene glycol, ii- at least one ester chosen from C16-C22 fatty acid esters of sorbitan and C16-C22 fatty acid esters of glycerol, d) at least one starch grafted with an acrylic polymer, and e) at least one starch not grafted with an acrylic polymer.

[0021] Against all expectations, the inventors have found that the use, in an oil-in-water emulsion stabilized by what is known as a "span-myrj" surfactant system, of the combination of starch and of a polymer, in particular superabsorbent polymer, chosen from starches grafted with an acrylic polymer, makes it possible to obtain a formulation with a thick texture, of characteristic "cushion" type under the finger on spreading, and non-tacky sensory properties, identical to that obtained with the fully synthetic polymeric microplastic fillers.

[0022] Advantageously, the use of the combination of a superabsorbent polymer chosen from starches grafted with an acrylic polymer and of a simple starch, that is to say a starch not grafted with an acrylic polymer, in an O/W emulsion with a particular surfactant system, commonly called "Span-Myrj", makes it possible to obtain a stable formulation having a thick "cushion" texture at the start of application and a silky, non-tacky sensory quality and skin feel during and after application that are particularly pleasant for daily use, and a comfort that is much appreciated by users accustomed to creams in jars containing synthetic microplastic powders.

[0023] Thus, the combination of an, in particular superabsorbent, polymer chosen from starches grafted with an acrylic polymer, and of a starch not grafted with an acrylic polymer, in an O/W emulsion, stabilized by a particular surfactant system of "Span-Myrj" type, advantageously makes it possible to combine properties which generally oppose each other: thickness of texture on application and silky skin finish. To begin with, superabsorbent polymers such as starches are known and used for their gelling properties. There was nothing to suggest that, once combined, they might confer the above-mentioned particular sensorial properties, that is to say a "cushion effect" under the finger and a silky skin finish, characteristic properties that to date have only been observed with the use of microplastic fillers. [0024] A subject of the invention, according to another of its aspect, is also the use of a composition as defined above, for caring for keratin materials, in particular bodily and/or facial skin.

[0025] A subject of the present invention is also the use, in a cosmetic composition in the form of an oil-in-water emulsion, of at least 2 types of starch as defined above, for increasing the thickness under the finger, in particular for providing a "cushion effect", at the start of application of the composition to the skin and for improving the skin finish by reducing tack and increasing the powdery effect perceived on the skin after application.

[0026] Another subject of the invention, according to yet another of its aspects, is a non- therapeutic cosmetic process for making up and/or caring for keratin materials, in particular the bodily and/or facial skin, comprising at least the application to said keratin materials of a composition as defined above.

[0027] The invention also relates to a non-therapeutic cosmetic process for limiting the drying- out of the skin and/or improving the suppleness and/or comfort of the skin, comprising the application, to the surface of the keratin material, of at least one composition as defined previously.

[0028] The invention also relates to a non-therapeutic cosmetic process for preventing and/or treating the signs of ageing of a keratin material, comprising the application, to the surface of the keratin material, of at least one composition as defined previously.

[0029] For the purposes of the present invention:

- The term "stable composition " is intended to mean a composition which, after storage for at least one month, and preferably two months, at ambient temperature (25°C), at 4°C and at 45°C, retains its pleasantness and its sensory signature on application. More specifically, for the purposes of the present invention, the term " stable composition " is intended to mean an acceptable change in viscosity, that is to say that the difference between the initial viscosity and the viscosity after storage for at least one month, and preferably two months, at ambient temperature (25°C) and at 4°C remains less than 10%, and at 45°C this difference remains less than 25%. For the purposes of the present invention, a "stable composition " exhibits moreover a difference between the initial pH and the pH after storage for at least one month, and preferably two months, at ambient temperature (25°C), at 4°C and at 45°C, of less than 0.3 and does not exhibit any phase separation phenomenon after storage for at least one month, and preferably two months, at ambient temperature (25°C), at 4°C and at 45°C. Finally, for the purposes of the present invention a " stable composition " does not exhibit crystals after storage for at least one month, and preferably two months, at ambient temperature (25 °C), at 4°C and at 45°C.

[0030] Other characteristics, aspects and advantages of the invention will become apparent on reading the detailed description which follows.

[0031] The composition according to the invention is intended for topical application and thus contains a physiologically acceptable medium. The term "physiologically acceptable medium" is understood here to mean a medium which is compatible with keratin materials.

[0032] In the context of the present invention, the term "keratin material" notably means the skin, the scalp, keratin fibres such as the eyelashes, the eyebrows, head hair, bodily hair, the nails, and mucous membranes such as the lips, and more particularly the skin and the mucous membranes (of the body, face, area around the eyes, eyelids, lips, preferably of the body, face and lips).

[0033] In the text which follows, unless otherwise indicated, the limits of a range of values are included in that range, notably in the expressions "between" and "ranging from ... to ...".

[0034] Moreover, the expressions "at least one" and "at least" used in the present description are equivalent to the expressions "one or more" and "greater than or equal to", respectively.

[0035] Starch grafted with an acrylic polymer

[0036] The composition according to the present invention comprises at least one starch grafted with an acrylic polymer. Advantageously, said at least one starch grafted with an acrylic polymer is chosen from starches grafted with an acrylic homo- or copolymer, in particular starches grafted with sodium polyacrylate. Specifically, the acrylic polymer may be a homopolymer or a copolymer, in particular sodium polyacrylate.

[0037] Advantageously, said starch grafted with an acrylic polymer is a superabsorbent polymer.

[0038] The term "superabsorbent polymer" is intended to mean a polymer that is capable in its dry form of spontaneously absorbing at least 20 times its own weight of aqueous fluid, in particular of water and especially distilled water. Such superabsorbent polymers are described in the work "Absorbent polymer technology, Studies in polymer science 8" by L. Brannon- Peppas and R. Harland, published by Elsevier, 1990. [0039] These polymers have a large capacity for absorbing and retaining water and aqueous fluids. After absorption of the aqueous liquid, the polymer particles thus engorged with aqueous fluid remain insoluble in the aqueous fluid and thus conserve their individualized particulate state.

[0040] The superabsorbent polymer may have a water-absorbing capacity ranging from 20 to 2000 times its own weight (i.e. 20 g to 2000 g of absorbed water per gram of absorbent polymer), preferably from 30 to 1500 times and better still from 50 to 1000 times. These water absorption characteristics are defined under standard temperature (25°C) and pressure (760 mmHg, i.e. 100 000 Pa) conditions and for distilled water. The value of the water-absorbing capacity of a polymer may be determined by dispersing 0.5 g of polymer(s) in 150 g of a water solution, waiting for 20 minutes, filtering the unabsorbed solution through a 150 pm filter for 20 minutes and weighing the unabsorbed water.

[0041] The superabsorbent polymer used in the composition of the invention is in the form of particles. Preferably, the superabsorbent polymer has, in the dry or nonhydrated form, a mean size of less than or equal to 100 pm and preferably less than or equal to 50 pm, for example ranging from 1 to 100 pm, preferably from 5 to 50 pm and better still from 7 to 30 pm.

[0042] The mean size of the particles corresponds to the mass-average diameter (D50) measured by laser particle size analysis or another equivalent method known to those skilled in the art. These particles, once hydrated, swell while forming soft particles having a mean size that can range from 10 pm to 1000 pm.

[0043] Such polymers are known for their gelling properties and are generally used in a form pre-swollen in aqueous phase.

[0044] In the present invention, the starch grafted with an acrylic polymer is added at the same time as the ungrafted starch, as fillers, generally at the end of formulation. Said combination of these two specific starches according to the invention confers in particular a cushion-effect thickness during take up with the finger, and then a powdery skin finish, after application of the emulsion of the invention. These two sensorial effects are typically those observed for synthetic polymeric fillers of the Expancel® type, here replaced by more natural raw materials used according to the invention.

[0045] According to a particular embodiment of the invention, the superabsorbent polymer(s) used comprise from 85% to 95% by weight of sodium polyacrylate and from 5% to 15% by weight of starch. Preferably, they are constituted of 90% by weight of sodium polyacrylate and 10% by weight of starch.

[0046] According to a particular embodiment of the invention, the molecular weight of the superabsorbent polymer(s) used is greater than 1000 daltons.

[0047] Mention may particularly be made of starches grafted with an acrylic polymer and in particular with sodium polyacrylate, such as those sold under the name Sanfresh ST-100MC by Sanyo Chemical Industries or Makimousse 25, Makimousse 12 or Makimousse 7 by Daito Kasei (INCI name: Sodium polyacrylate starch).

[0048] The superabsorbent polymers used in the present invention may be crosslinked or non- crosslinked.

[0049] The superabsorbent polymers used in the present invention are preferably starches grafted with an acrylic homo- or copolymer, in particular sodium polyacrylate, which is in particulate form.

[0050] Preferably, the superabsorbent polymer is chosen from starches grafted with an acrylic homopolymer, preferably in the form of particles having a mean size (or mean diameter) of less than or equal to 100 microns, more preferably in the form of particles.

[0051] Said grafted, advantageously superabsorbent, starch(es) is/are present in an active material content ranging from 0.05% to 1% by weight, preferably from 0.06% to 0.5% by weight, preferably ranging from 0.07% to 0.2% by weight, preferably from 0.08% to 0.15% by weight, preferentially from 0.09% to 0.12% by weight, relative to the total weight of the composition.

[0052] Starch not grafted with an acrylic polymer

[0053] For the purposes of the invention, the term "ungrafted starch" is intended to mean a starch which is not grafted with an acrylic polymer, in particular a starch which does not form part of the superabsorbent polymers as defined above.

[0054] Thus, the cosmetic composition according to the invention additionally comprises starch, simple starch, that is to say starch which is not grafted with an acrylic polymer. The ungrafted starch represents a content ranging from 0.1% to 5% by weight, and more preferentially from 0.5% to 2% by weight, preferably from 0.5% to 1.5% by weight, preferably from 1% to 1.2% by weight, relative to the total weight of the composition. Of course, the content is expressed in terms of active material. [0055] The starches that may be used in the present invention are more particularly macromolecules in the form of polymers consisting of elementary moieties which are anhydroglucose units (dextrose), linked via a(l,4) bonds, of chemical formula (C6H10O5)n. The number of these moieties and their assembly make it possible to distinguish amylose, a molecule formed from about 600 to 1000 linearly linked glucose molecules, and amylopectin, a polymer branched approximately every 25 glucose residues (a(l,6) bond). The total chain may include between 10000 and 100000 glucose residues.

[0056] Starch is described in particular in Kirk-Othmer’s Encyclopedia of Chemical Technology, 3rd edition, volume 21, pages 492-507, Wiley Interscience, 1983.

[0057] Chemical structure of starch:

[0058] Dextrose [0064] The relative proportions of amylose and of amylopectin, and their degree of polymerization, vary as a function of the botanical origin of the starches. On average, a sample of native starch consists of about 25% amylose and 75% amylopectin.

[0065] Occasionally, phytoglycogen is present (between 0 and 20% of the starch), which is an analog of amylopectin but branched every 10 to 15 glucose residues.

[0066] Starch may be in the form of semicrystalline granules: amylopectin is organized in sheets, amylose forms a less well organized amorphous zone between the various sheets.

[0067] Amylose is organized in a right-handed helix with six glucoses per turn. It dissociates into assimilable glucose under the action of enzymes, amylases, all the more easily when it is in amylopectin form. Specifically, the helical formation does not promote the accessibility of the starch to the enzymes.

[0068] Starches are generally in the form of a white powder, which is insoluble in cold water, of which the elemental particle size ranges from 3 to 100 microns.

[0069] By treating it with hot water, starch paste is obtained. It is exploited in industry for its thickening and gelling properties.

[0070] In contrast, in the case of the present invention, starch is used as a sensorial filler. The two particular types of starch combined in the compositions according to the invention remain detectable in the particulate state in the formulation when subjected to scanning electron microscopy (xlOO).

[0071] Advantageously, in the composition according to the invention, the ungrafted starch and the grafted starch are provided and are then found in the formulation in particulate form, irrespective of whether they are in the swollen or non-swollen state, in particular as a result of impregnation of the formulation, in particular in the hydrated or non-hydrated state.

[0072] The botanical origin of the starch molecules used in the present invention may be cereals or tubers. Thus, the starches are chosen, for example, from com starch, rice starch, cassava starch, tapioca starch, barley starch, potato starch, wheat starch, sorghum starch and pea starch.

[0073] The native starches are represented, for example, by the products sold under the trade names C*Amilogel®, Cargill Gel®, C*Gel®, Cargill Gum®, DryGel® and C*Pharm Gel® by the company Cargill, under the name Amidon de Mais by the company Roquette, and under the name Tapioca Pure by the company National Starch. [0074] Advantageously, said at least one ungrafted starch is chosen from: corn starch, tapioca starch, rice starch, wheat starch, cassava starch, barley starch, potato starch, sorghum starch, pea starch, and mixtures thereof.

[0075] Preferably, the ungrafted starch is chosen from com starch, tapioca starch, rice starch or wheat starch. It may be modified or unmodified (also referred to as "native").

[0076] Preferably, the starch not grafted with an acrylic polymer is not modified chemically or physically, either. Preferably, said ungrafted starch is not modified by crosslinking by functional agents capable of reacting with the hydroxyl groups in the starch molecules, either.

[0077] Preferably, said ungrafted starch is native starch. Preferably, the ungrafted starch is native com starch.

[0078] The ungrafted starch used in the composition of the invention is in particulate form. The mean size of the ungrafted starch particles, corresponding to the mass-average diameter (D50) measured by laser particle size analysis, in the dry or nonhydrated state, is within the range from 5 to 30 pm, preferably from 5 to 20 pm, preferably from 10 to 20 pm.

[0079] Advantageously, the grafted starch/ungrafted starch weight ratio is within the range from 1/8 to 1/15, preferably from 1/10 to 1/15, preferably from 1/10 to 1/12. Below 1/15, the cushion effect is less and less perceptible, and above 1/8, an increasingly thick texture, or even a pasty effect, may appear.

[0080] Fatty acid ester of polyethylene glycol

[0081] The composition according to the invention comprises, as principal emulsifying surfactant, at least one fatty acid ester of polyethylene glycol.

[0082] The fatty acid ester of polyethylene glycol present in the composition according to the invention is preferably a C16-C22 fatty acid ester comprising from 8 to 100 ethylene oxide units.

[0083] The fatty chain of the esters may be chosen especially from stearyl, behenyl, arachidyl, palmityl and cetyl units, and mixtures thereof, such as cetearyl, and preferably a stearyl chain.

[0084] The number of ethylene oxide units may range from 8 to 100, preferably from 10 to 80, and better still from 10 to 50. According to a particular embodiment of the invention, this number may range from 20 to 40. [0085] As examples of faty acid esters of polyethylene glycol, mention may be made of stearic acid esters respectively comprising 20, 30, 40, 50 and 100 ethylene oxide units, such as the products respectively sold under the names Myrj 49 P (polyethylene glycol 20 EO stearate; CTFA name: PEG-20 stearate), Myrj 51, Myrj 52 P (polyethylene glycol 40 EO stearate; CTFA name: PEG-40 stearate), Myrj 53 and Myrj 59 P by the company Croda.

[0089] The composition according to the invention also comprises at least one addition emulsifying surfactant chosen from C16-C22 fatty acid esters of sorbitan and C16-C22 fatty acid esters of glycerol, and mixtures thereof.

[0090] According to a first embodiment of the invention, the composition comprises a C16- C22 fatty acid ester of sorbitan.

[0091] The C16-C22 fatty acid esters of sorbitan are formed by esterification with sorbitol of at least one fatty acid comprising at least one saturated or unsaturated linear alkyl chain respectively having from 16 to 22 carbon atoms. These esters may be chosen especially from sorbitan stearates, behenates, arachidates, palmitates or oleates, and mixtures thereof. Use is preferably made of sorbitan stearates and palmitates, and preferentially sorbitan stearates.

[0092] The C16-C22 fatty acid ester of sorbitan present in the composition according to the invention is advantageously solid at a temperature of less than or equal to 45°C.

[0093] As examples of sorbitan esters that may be used in the composition according to the invention, mention may be made of sorbitan monostearate (CTFA name: Sorbitan stearate), sold by the company Croda under the name Span 60, sorbitan tristearate, sold by the company Croda under the name Span 65 V, sorbitan monopalmitate (CTFA name: Sorbitan palmitate), sold by the company Croda under the name Span 40, sorbitan monooleate, sold by the company Croda under the name Span 80 V, and sorbitan trioleate, sold by the company Uniqema under the name Span 85 V. Preferably, the sorbitan ester used is sorbitan tristearate. [0094] Advantageously, the composition according to the invention comprises a C16-C22 fatty acid ester of sorbitan chosen from sorbitan stearates, especially sorbitan tristearate.

[0095] The C16-C22 fatty acid ester of sorbitan may be present in the composition according to the invention in a content ranging from 0.01% to 10% by weight, preferably ranging from 0.01% to 5% by weight and preferentially ranging from 0.1% to 3% by weight, relative to the total weight of the composition.

[0096] The fatty acid ester of glycerol may especially be obtained from an acid comprising a saturated linear alkyl chain containing from 16 to 22 carbon atoms. Fatty acid esters of glycerol that may in particular be mentioned include glyceryl stearate (glyceryl mono-, di- and/or tristearate) (CTFA name: Glyceryl stearate) or glyceryl ricinoleate, and mixtures thereof. Preferably, the fatty acid ester of glycerol used is chosen from glyceryl stearates.

[0097] The fatty acid ester of glycerol may be present in an amount ranging from 0.1% to 10% by weight, relative to the total weight of the composition, preferably ranging from 1% to 6% by weight and preferentially ranging from 2% to 5% by weight, with respect to the total weight of the composition.

[0098] Advantageously, the composition of the invention comprises a mixture of glyceryl stearate and of polyethylene glycol monostearate, preferably comprising 40 EO.

[0099] The composition of the invention may especially comprise a mixture of glyceryl stearate and of polyethylene glycol 100 EO monostearate and in particular that comprising such a mixture in 50/50 weight proportion, sold under the name Arlacel 165 by the company Croda.

More preferably, the composition according to the present invention comprises a mixture of at least : a fatty acid ester of polyethylene glycol, a C16-C22 fatty acid ester of sorbitan, a starch grafted with an acrylic polymer, and a starch not grafted with an acrylic polymer, especially a non-modified starch, preferably a native starch. This preferred surfactant system described above, especiallly combining a fatty acid ester of polyethylene glycol and a C16-C22 fatty acid ester of sorbitan, is advantageous for the specific texture which it confers on these emulsions. The latter have a thick texture and are suitable for packaging of the cosmetic product in a pot (in contrast to fluid textures, which are packaged in a tube or in a pump-action spray; the thick texture is such that the composition does not flow instantaneously on turning the pot upside down); such a composition can be easily taken up with the fingers and spreads well and pleasantly over the skin while readily penetrating it; it confers softness and does not exhibit a tacky effect.

[00101] Advantageously, the composition of the invention comprises a mixture of sorbitan stearate, preferably sorbitan tristearate, of glyceryl stearate and of polyethylene glycol monostearate, preferably comprising 40 EO.

[00202] The invention will now be illustrated with the aid of the non-limiting examples that follow.

Examples

[00203] The examples that follow serve to illustrate the invention without, however, being limiting in nature. In these examples, the amounts of the ingredients of the compositions are given as % by weight of starting materials, relative to the total weight of the composition. The compositions are prepared according to the procedure described above.

[00204] Example 1 - Compositions 1 to 2

[Table 1]

[00205] Example 2 - Compositions 3 to 4

[Table 2]

[00206] Stability study

The stability of the compositions is evaluated macroscopically (appearance, color, odor, pH and viscosity) and microscopically at 1 month and at 2 months at ambient temperature, at 4°C and at 45°C. All of the compositions below (1, 2, 3 , 4) proved to be stable at 2 months under these conditions.

[00207] The composition stability results are as follows (table 3).

[Table 3]

[00208] Sensory evaluation

[00209] For each of the compositions, the cosmetic properties were evaluated according to the following protocol. The cosmetic properties on application are evaluated, monadically, by a panel of 20 experts trained in the description of care products. The sensory evaluation of the care products by this panel is performed as follows: the products are packaged in jars. Within one and the same session, the samples are presented in random order to each panel member. 20 experts evaluate the descriptors during the different steps, according to table 4 below: first the appearance, then the uptake in the hand, and the application of a drop of product (0.05 ml) respectively onto the back of the hand, the inner face of the forearm, and then the face, and lastly evaluate the tack 2 minutes after application.

[00210] Table 4 below indicates the descriptors evaluated according to the step of application of the composition:

[Table 4]

[00211] The descriptors are evaluated visually under standardized light, and sensorially, according to a scale rated from 1 to 15: in this scale in particular 1 = not, 4 = barely, 8 = moderately, 12 = fairly, 15 = very.

[00212] The descriptors are defined below, along with the procedure therefor.

[00213] Appearance of the product: [00214] Smooth the surface of the producf beforehand using a spatula in order to visually evaluate the following descriptors under standardized light:

[00215] 1- Sheen: Capability of the product to reflect light.

[00216] 2- Smoothness: Appearance of the surface without bumps, grains, bubbles or reliefs.

[00217] 3- Transparency: Capability for allowing light to pass.

[00218] 4- Fluidity: Characterizes the liquid appearance of the product.

[00219] 5- Wobble: The wobble characterizes the elasticity of the product, its capacity to return elastically to its original place after having tapped the pot (English jelly type).

[00220] Take-up of the product:

[00221] 6- Adherence to the finger: Amount of product adhering to the finger after placing the index finger onto the product.

[00222] 7- Stringiness: Capability for forming a continuous visible thread, after having placed the index finger delicately onto the surface of the product and lifting it up once rapidly by 10 cm.

[00223] 8- Consistency: Force required to trace a line in the product: using the square end of a small spatula, sticking it into the jar over the entire height, and then pulling it across the entire diameter of the jar.

[00224] 9- Keeps its shape: the more the product returns to its initial shape, the less it

"keeps its shape". Observe the change in deformation that occurs during the evaluation of the consistency after 5 seconds of waiting.

[00225] 10- Thickness: Perception of a thick film between the thumb and the index finger

(the less thick the product, the more the fingerprints are felt). The thickness of the product is evaluated tactilely. Deposit 50 mΐ of product using a pipette to the first phalanx of the index finger and evaluate the thickness of the product between the thumb and the index finger, performing 4 rotational movements.

[00226] Application of the product to the back of the hand:

[00227] 11- White film: The product forms a white film during application. [00228] Procedure (actions): Take 50 mΐ of product, apply it to a first half of the back of the hand; perform 5 turns with the index finger and the middle finger. The white film of the product is evaluated visually over the 5 turns.

[00229] 12- Soaping: Formation of a fine foam during massaging.

[00230] Procedure (actions): Take 50 mΐ of product, apply it to the second half of the back of the hand, rub it very rapidly for 5 seconds with the index finger and the middle finger. The "soaping" is evaluated visually over the course of this vigorous massaging.

[00231] Application of the product to the inner face of the forearm:

[00232] 13- Greasiness: Greasy sensation on application.

[00233] Procedure (actions): Take 100 mΐ of product, apply it to the inner face of the forearm. The greasiness is then evaluated tactilely over 5 rotational movements.

[00234] 14 to 19- Glide 1, 5, 10, 15, 20, and 25 turns: Ease with which the fingers turn during application of the cream.

[00235] Procedure (actions): Take 100 mΐ of product, apply it to the inner face of the forearm. The criterion is evaluated tactilely on the first turn and on the 5th, 10th, 15th, 20th and 25th turn.

[00236] Application of the product to a half-face:

[00237] Take 100 mΐ of product. Apply this amount to the cheek, for the successive evaluation of the freshness and of the speed of penetration (over 8.5 turns). Application is performed on the cheek: Perform two central turns and then 6 wider turns. Finish by spreading once from the bridge of the nose towards the eair and then the jaw.

[00238] 20- Freshness: Capability for providing a sensation of freshness.

[00239] 21- Speed of penetration: Speed with which the product is absorbed by the skin, associated with the sensation of disappearance of the product.

[00240] 22- Fingers remain greasy: Greasy sensation on the fingers after application.

[00241] Procedure (actions): After having performed 8.5 rotational movements on the cheek. Roll the fingers (thumb, index finger and middle finger) to quantify the greasiness remaining just after application to the face. The evaluation is tactile, and is done during the 6th rolling action of the fingers. [00242] 23- Immediate tacky skin: Capability of the product to adhere to the back of the hand.

[00243] Procedure (actions): The tackiness effect of the product is evaluated tactilely. This criterion is evaluated by placing the back of the hand against the cheek which received the product and then removing it from the cheek, a maximum of two times. (This evaluation is made after the actions freshness, speed of penetration and fingers remaining greasy, which corresponds to 15 seconds after application to the face).

[00244] 2 minutes after application of the product to the face:

[00245] Wait 2 minutes after the end of application. During this time, wash the hands and the forearm with water and soap. Dry them by patting with a towel.

[00246] For all the descriptors of skin finish evaluation the evaluation area is the cheek.

[00247] 24- Shiny skin: Film which reflects light.

[00248] Procedure (actions): The shiny effect of the product is evaluated visually using a small mirror and under standardized light.

[00249] 25- White skin: Capability of foiming a white film during application.

[00250] Procedure (actions): The whitening effect of the product is evaluated visually using a small mirror and under standardized light.

[00251] 26- Tacky skin: Capability of the product to adhere to the back of the hand.

[00252] Procedure (actions): The tackiness effect of the product is evaluated tactilely.

This criterion is evaluated by placing the back of the hand against the cheek which received the product and then removing it from the cheek.

[00253] 27- Slippery skin: No dragging sensation perceived.

[00254] Procedure (actions): Gentle touching of the skin which received the product with the back of the fingers.

[00255] 28- Film forming: Film remaining present on the skin (comfort effect) and being able to be removed.

[00256] Procedure (actions): The film forming is evaluated tactilely, slight pinching movement of the skin between the thumb, the index finger and the middle finger.

[00257] The results of the sensorial analysis are indicated: - on the graph of figure 1, for compositions Cpl (dashed) and Inv2 (solid line)

- on the graph of figure 2, for compositions Cp3 (dashed) and Inv4 (solid line)

Each graph indicates on the abscissa the score obtained (between 0 and 15) for each descriptor number indicated on the ordinate (descriptor numbers 1 to 28 of table 4 and as defined above).

[00258] On the two graphs, the solid line curve is that of the composition Inv2 and Inv4, respectively, according to the invention, while the dashed curve is that of the composition Cpl and Cp3, respectively, outside the invention (comparative).

[00259] It is observed that, on each of the graphs, the two curves overlap one another; the scores obtained for each descriptor are substantially identical (the rare and slight differences are considered not to be significant).

[00260] The composition according to the invention, comprising as fillers the combination of a native corn starch and a polyacrylate-grafted starch, exhibit the same sensory profile as a composition comprising as fillers synthetic polymeric particles of wholly petroleum origin, typically used to obtain the type of characteristic sensory profile sought: thickness under the finger (see number 10) on application and powdery skin finish (non-tacky skin, see number 26) and comfort sensation of the skin (by virtue of the presence of a light film, see number 28) after application of the composition to the skin.

[00261] Example 3 - Comparison of the texture under the finger and of the skin finish for different types and contents of fillers in the compositions Cp5. Cp6. Cp7. Cp8. and Inv6

[00262] [Table 5]

[00263] The compositions outside the invention comprising, as filler, silica Cp5 (2% silica), or a combination of silica and polyacrylate-grafted starch Cp6 to Cp8, exhibit a skin finish which is judged to be too dry by the panel of trained experts. The dry and not very comfortable effect is associated in particular with the absence of film (number 28) on the skin after application of the composition.

[00264] In contrast, the compositions according to the invention, as evaluated by the same panel of experts, and comprising the combination of native corn starch and polyacrylate- grafted starch (Inv2 and Inv9) are characterized by a notable thickness (perceived cushion effect) under the finger at the start of application (number 10), followed by a comfortable (non dry) non-tacky powdery skin finish after application of each of the 2 compositions according to the invention (Inv2 and Inv9), by virtue of the presence of a non-tacky (numbers 26 and 27) film (associated with criteria numbers 21 and 28) on the skin after application of the composition.

[00265] Example 4 - Comparison of the texture under the finger and of the skin finish for different types of fillers in the compositions CpT Cp9. Cp 10. and Inv2

[00266] [Table 6]

[00267] Cpl is the thick, smooth cream containing 0.5% of Expancel®, of the prior art, characterized by a notable thickness, a perceived cushion effect ("thickness" number 10) under the finger at the start of application, and a comfortable powdery skin finish associated with the presence of a non-tacky (numbers 26 and 27) film (numbers 21 and 28) on the skin after application of the composition.

[00268] Replacing the Expancel®, in the presence of a single type of filler of ungrafted starch type in the composition Cp9, there is no thickness (number 10) under the finger at the start of application and the skin finish obtained is additionally judged by the panel of experts as: too dry, not very comfortable, associated with the lack of a film (number 28) and with excessively rapid penetration (number 21) of the composition.

[00269] In the presence of a single type of filler of polyacrylate-grafted starch type (Cp 10) at a content of 0.5%, the composition exhibits an unacceptable foamy, pasty appearance, instead of forming a smooth cream like Cpl . [00270] In contrast, the composition according to the invention, evaluated by the same panel of experts, and comprising the combination of native corn starch and polyacrylate-grafted starch (Inv2), is characterized, like Cpl, by a notable thickness and in particular a perceived cushion effect ("thickness" number 10 virtually identical to that of Cpl) under the finger at the start of application, followed by a comfortable non-tacky powdery skin finish (presence of a film on the skin) after the application of the composition according to the invention (Inv2).

[00271] Example 5: Evaluation by consumers of the two creams of example 1 above (Cpl and Inv2)

[00272] The purpose of this "consumer test" is to evaluate the perceived performance for the new composition (without microplastic filler) according to the invention Inv2, compared to that of the customary product of composition Cpl (with Expancel®), which is the customary anti-ageing night cream for the panel. In this test, the panel of testers is made up of 164 women aged from 50 to 79 years, who are users (at least 4 times per week) of the anti-ageing face night care composition Cpl, a widely used product on the market.

[00273] Monadic, sequential test of use at home, each woman tested 2 products (current Cpl vs. new formulation Inv2) under blind conditions.

[00274] Results: The perceived performance is perfectly identical for both products for the key attributes of this type of product:

[00275] - Regeneration of the skin and firmness

[00276] - Anti-ageing effect on the uniformity of the complexion,

[00277] - Anti-ageing effect on the smoothing of wrinkles and of the skin,

[00278] - Moisturization throughout the day

[00279] - Pleasant appearance,

[00280] - Pleasant texture and application,

[00281] - Immediate skin finish,

[00282] - Immediate moisturization and comfort,

[00283] - Sensation of comfort.

[00284] The formulation thus modified according to the invention, free from microplastic fillers and instead comprising a combination of more natural fillers, meets the objective of parity with the characteristic performance qualities perceived for the conventional formulation Cpl comprising microplastic fillers. The efficacy, perceived by regular users of the conventional formulation Cpl, is identical for the 9 above-mentioned criteria in the case of the formula Inv2 according to the invention.

[00285] In summary, the present invention made it possible to replace certain microplastic fillers with the combination of 2 specific, in particular particulate, starches, and to thus obtain more natural formulations that are more environmentally friendly, achieving this without the texture or the sensory profile of the formulation being modified and without any compromise in the performance perceived by users of the formulation.
