Description:
COMPOSITION IN THE FORM OF AN EMUFSION COMPRISING A SIFICONE RESIN AND AN AMINO SIFICONE OIF, AND PROCESS USING THE SAME

The present invention relates to a composition, intended in particular for making up and/or caring for the lips and the skin, presented in the form of an emulsion, comprising at least 10% by weight of water, at least 10% by weight of a silicone resin, at least 4% by weight of at least one amino silicone oil, and also to a process for treating and/or making up keratin materials, for instance the skin or the lips, in particular the lips, using said composition.

The development of compositions for making up and/or caring for the lips, in particular fluid compositions such as liquid lipsticks, which are stable and endowed with satisfactory properties in terms of application (glidance on application, ease of spreading and fineness of the deposit), but also in terms of the makeup effect of the deposit on the lips, for instance the absence of migration of the deposit, preferably without becoming tacky, is an ongoing objective.

Generally, formulations corresponding to liquid presentation forms are conventionally anhydrous and comprise oils, which in particular provide gloss, optionally waxes for structuring the compositions, fillers especially for thickening the composition, film-forming polymers, and dyestuffs.

These liquid lipsticks must be sufficiently fluid to be easily applied, but not too fluid, so as not to degrade the stability of the composition (pigment sedimentation) and the ease of application (running).

With conventional liquid lipstick compositions, it is noted that the deposit is relatively thick, thereby giving it a more or less tacky nature, especially induced by the use of these oils and of the polymers present. This nature may be reflected especially by adhesion of the made-up lips to each other, causing the user an unpleasant sensation in terms of comfort.

Liquid lipstick compositions have for some time appeared on the market, in the form of direct or inverse aqueous emulsions. When they are applied, they provide a fresh effect, and are sparingly tacky or non-tacky, and comfortable, and remain so once deposited. They also make it possible to obtain a homogeneous, sufficiently glossy deposit which has satisfactory persistence and transfer resistance.

Nevertheless, it is desired to further improve the gloss and the persistence of the gloss of these compositions, and also the colour persistence, without losing any comfort or adversely affecting the transfer resistance. It is also advantageous to have available compositions that can be applied both to the lips and to the skin, in particular to the face and more precisely the cheeks.

Liquid compositions, in particular creamy compositions, which can produce a deposit whose gloss, and also the persistence of the gloss are improved without having an excessively adverse effect on the transfer resistance properties and without any loss of comfort or increase in tackiness, are thus sought. Compositions of which the deposit on the lips or the skin, in particular the cheeks, although very thin, makes it possible to obtain a visible colour, with improved colour persistence, are also sought. These aims and others are achieved by the present invention, one subject of which is a cosmetic composition in the form of emulsion, comprising:

• at least 10% by weight of water, relative to the weight of the composition;

• at least 10% by weight, relative to the weight of the composition, of at least one silicone resin;

• at least one amino silicone oil;

• optionally at least one non-volatile silicone oil

• optionally at least one non-volatile silicone oil, free of (poly)glycerol and (poly)oxyalkylene groups, the oxyalkylene group being C2-C3;

• the content of amino silicone oil being at least 4% by weight, relative to the weight of the composition if the composition does not comprise any abovementioned non-volatile silicone oil(s).

The film deposited on the lips has the advantage of being thin and affords a fresh effect on application, without significant migration into the wrinkles and fine lines.

The composition is stable, easy to apply, comfortable on application since the deposit obtained is sparingly tacky or non-tacky, and remains so once in place. Moreover, the deposit does not give an impression of dryness of the lips, does not crack and keeps the lips mobile.

ln addition, the deposit obtained by applying the composition according to the invention has improved gloss coupled with good persistence of the gloss over time ln addition, the transfer resistance remains satisfactory.

Finally, the colour persistence of the deposit obtained by applying the composition is improved. ft should be noted that, in the remainder of the description, unless otherwise indicated, the limits indicated for a range are included in that range.

The expressions "at least one" and "several" are used without distinction.

Unless otherwise indicated, the percentages are on a weight basis, relative to the total weight of the composition.

ln addition, the sum of the amounts of the ingredients of the composition represents 100% by weight of the composition.

The composition according to the invention may advantageously be in very variable forms, ranging from fluid (relatively sparingly viscous) compositions to very viscous compositions.

Thus, the compositions according to the invention may have a viscosity at 25°C of between 0.01 and 15 Pa.s, more particularly ranging from 0.05 to 12 Pa.s.

Protocol for measuring the viscosity: The viscosity measurement is generally performed at 25°C, using a Rheomat RM 100 viscometer equipped with a no. 2, 3 or 4 spindle, depending on the viscosity, the measurement being performed after 10 minutes of rotation of the spindle in the composition, at a shear rate of 200 revolutions/min (rpm).

SILICONE RESIN

As indicated previously, the composition according to the invention comprises at least one silicone resin.

More generally, the term "resin" means a compound whose structure is three-dimensional. Thus, for example, a polydimethylsiloxane is not a silicone resin for the purposes of the present invention.

The nomenclature of silicone resins (also known as siloxane resins) is known under the name "MDTQ", the resin being described as a function of the various siloxane monomer units it comprises, each of the letters "MDTQ" characterizing a type of unit.

The letter M represents the monofunctional unit of formula RlR2R3SiOi /2 , the silicon atom being bonded to only one oxygen atom in the polymer comprising this unit.

The letter D means a difunctional unit RlR2Si0 2/2 in which the silicon atom is bonded to two oxygen atoms.

The letter T represents a trifunctional unit of formula Rl Si03 / 2.

Such resins are described, for example, in the Encyclopedia of Polymer Science and Engineering, vol. 15, John Wiley and Sons, New York, (1989), pp. 265-270, and US 2 676 182, US

3 627 851, US 3 772 247, US 5 248 739 or else US 5 082 706, US 5 319 040, US 5 302 685 and US

4 935 484.

In the units M, D and T defined previously, Ri, namely Ri, R 2 and R 3 , which may be identical or different, represent a hydrocarbon-based radical (especially alkyl) containing from 1 to 10 carbon atoms, a phenyl group, a phenylalkyl group or else a hydroxyl group.

Finally, the letter Q means a tetrafunctional unit S1O4/2 in which the silicon atom is bonded to four oxygen atoms, which are themselves bonded to the rest of the polymer.

Various silicone resins with different properties may be obtained from these different units, the properties of these polymers varying as a function of the type of monomer (or unit), the nature and number of the radical(s) Ri, the length of the polymer chain, the degree of branching and the size of the side chains.

As silicone resins that may be used in the compositions according to the invention, use may be made, for example, of silicone resins of MQ type, of T type or of MQT type.

MQ resins:

As examples of silicone resins of MQ type, mention may be made of the alkyl siloxysilicates of formula [(Rl)3Si0i/2] x (Si04/2) y (units MQ) in which x and y are integers ranging from 50 to 80, and such that the group Rl represents a radical as defined previously, and is preferably an alkyl group containing from 1 to 8 carbon atoms or a hydroxyl group, preferably a methyl group.

As examples of solid silicone resins of MQ type of trimethyl siloxysilicate type, mention may be made of those sold under the reference SR1000 by the company Momentive Performance Materials, under the reference MQ 1600 by Dow Coming or under the reference Belsil TMS 803 by the company Wacker.

As silicone resins comprising MQ siloxysilicate units, mention may also be made of phenylalkyl siloxysilicate resins, such as phenylpropyldimethyl siloxysilicate (Silshine 151 sold by the company Momentive Performance Materials). The preparation of such resins is described especially in patent US 5 817 302.

T resins:

Examples of silicone resins of T type that may be mentioned include the polysilsesquioxanes of formula (RSi03 / 2) x (units T) in which x is greater than 100 and such that the group R is an alkyl group containing from 1 to 10 carbon atoms, said polysilsesquioxanes also possibly comprising Si- OH end groups.

Mention may also be made of polymethylsilsesquioxanes, which are polysilsesquioxanes in which none of the methyl radicals is substituted with another group. Such polymethylsilsesquioxanes are described, for example, in US 5 246 694.

Polymethylsilsesquioxane resins that may preferably be used are those in which R represents a methyl group, for instance those sold:

- by the company Wacker under the reference Resin MK, such as Belsil PMS MK: polymer comprising CTbSiCb repeating units (units T), which may also comprise up to 1% by weight of (CH 3 ) 2 Si0 2/2 units (units D) and having an average molecular weight of about 10 000 g/mol, or

- by the company Shin-Etsu under the references KR-220L, which are composed of units T of formula CEbSiOsa and contain Si-OH (silanol) end groups, under the reference KR-242A, which comprise 98% of units T and 2% of dimethyl units D and contain Si-OH end groups, or else under the reference KR-251, comprising 88% of units T and 12% of dimethyl units D and contain Si-OH end groups.

- by the company Dow Coming under the references Dow Corning 670 Fluid, Dow Coming 680 Fluid, as a mixture in cyclopentasiloxane and in isododecane, respectively.

MQT resins:

Among the fillers that may be used in the compositions according to the invention, mention may be made of silica, kaolin, starch, lauroyllysine, fumed silica particles, which are optionally hydrophilic -treated, mica, talc, sericite, polyamide (Nylon®) powder, roΐn-b-alaninc powder and polyethylene powder, powders of tetrafluoroethylene polymers (Teflon®), hollow polymer microspheres such as those of polyvinylidene chloride/acrylonitrile, for instance Expancel® (Nobel Industries), acrylic acid copolymer microspheres, silicone resin microbeads (for example Tospearls® from Toshiba), polyorganosiloxane elastomer particles, precipitated calcium carbonate, magnesium carbonate, magnesium hydrogen carbonate, hydroxyapatite, barium sulfate, aluminium oxides, polyurethane powders, composite fillers, hollow silica microspheres, glass or ceramic microcapsules, and metal soaps derived from organic carboxylic acids containing from 8 to 22 carbon atoms and preferably from 12 to 18 carbon atoms, for example zinc, magnesium or lithium stearate, zinc laurate and magnesium myristate, and mixtures thereof.

A composition used according to the invention may comprise one or more fillers in a content ranging from 0.1% to 10% by weight and in particular from 0.2% to 8% by weight relative to the weight of the composition.

LTPOPHTLTC THICKENER

The hydrophobic thickener may be chosen from mineral thickeners especially such as organophilic clays; hydrophobic fumed silicas; hydrophobic silica aerogels; from organic thickeners such as oil-gelling polymers of the block polymer type, especially triblock or star polymers, resulting from the copolymerization of at least one styrene monomer and of at least one hydrocarbon monomer bearing one or two C2-C5 ethylenic unsaturations, such as ethylene, propylene, butadiene, isoprene and/or pentadiene, such as the polymers sold under the name Kraton; polyamide resins comprising alkyl groups containing from 12 to 22 carbon atoms, such as those described in US-A-5 783 657; polysaccharide alkyl ethers, especially in which the alkyl group is of C1-C24, preferably C1-C10 and better still Ci-Ce, described especially in EP 898 958, and in particular alkyl guar gums (with a Ci- Ce alkyl group), such as those described in EP 708 114; esters of dextrin and of a fatty acid, preferably of C12 to C24, in particular C M -C IS , for example dextrin palmitate and dextrin myristate; N-acylglutamides in which the acyl group is a linear or branched C to C22 alkyl chain; preferably dialkyl N-acylglutamides, for instance lauroylglutamic acid dibutylamide or N-2-ethylhexanoyl glutamic acid dibutylamide; hydroxystearic acid; ethylenediamine stearyl dimer dilinoleate copolymer (sold, for example, under the name Oleocraft by Croda); and also mixtures thereof.

Preferably, when the composition comprises at least one hydrophobic thickener, this thickener is preferably chosen from mineral thickeners.

Clays are silicates containing a cation that may be chosen from calcium, magnesium, aluminium, sodium, potassium and lithium cations, and mixtures thereof. Examples of such products that may be mentioned include clays of the smectite family such as montmorillonites, hectorites, bentonites, beidellites and saponites, and also of the family of vermiculites, stevensite and chlorites. These clays may be of natural or synthetic origin. Organophilic clays are clays modified with a chemical compound chosen from quaternary amines, tertiary amines, amine acetates, imidazolines, amine soaps, fatty sulfates, alkyl aryl sulfonates and amine oxides, and mixtures thereof.

Mention may thus be made of hectorites modified with a quaternary amine, more specifically with a C 10 to C22 fatty acid ammonium halide, such as a chloride, such as hectorite modified with distearyldimethylammonium chloride (CTFA name: Disteardimonium hectorite), for instance the product sold under the name Bentone 38 V ® , Bentone 38V CG or Bentone EW CE by the company Elementis, or stearalkonium hectorites, such as Bentone 27 V.

Mention may also be made of quatemium-l 8 bentonites, such as those sold under the names Bentone 34 by the company Elementis, Tixogel VP by the company United Catalyst and Claytone 40 by the company Southern Clay; stearalkonium bentonites, such as those sold under the names Tixogel LG by the company United Catalyst and Claytone AF and Claytone APA by the company Southern Clay; or quatemium-l 8/benzalkonium bentonites, such as that sold under the name Claytone HT by the company Southern Clay.

According to a preferred embodiment, the thickener is chosen from organophilic modified clays, in particular organophilic modified hectorites, in particular modified with stearylbenzyldimethylammonium halides, preferably chlorides, or with distearyldimethylammonium chloride .

The hydrophobic firmed silicas may be obtained by modification of the surface of the silica via a chemical reaction that generates a reduction in the number of silanol groups, these groups possibly being substituted especially with hydrophobic groups. The hydrophobic groups may be:

- trimethylsiloxyl groups, which are obtained especially by treating fumed silica in the presence of hexamethyldisilazane. Silicas thus treated are known as Silica silylate according to the CTFA (6th Edition, 1995). They are sold, for example, under the references Aerosil R812® by the company Degussa, and Cab-O-Sil TS-530® by the company Cabot;

- dimethylsilyloxyl or polydimethylsiloxane groups, which are especially obtained by treating fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas thus treated are known as Silica dimethyl silylate according to the CTFA (6th Edition, 1995). They are sold, for example, under the references Aerosil R972® and Aerosil R974® by the company Degussa, and Cab-O-Sil TS-610® and Cab-O-Sil TS-720® by the company Cabot.

Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air. They are generally synthesized via a sol-gel process in a liquid medium and then dried, usually by extraction with a supercritical fluid, the one most commonly used being supercritical CO2. This type of drying makes it possible to avoid shrinkage of the pores and of the material. The sol-gel process and the various drying operations are described in detail in Brinker C.J. and Scherer G.W., Sol-Gel Science, New York: Academic Press, 1990.

Use will preferably be made of hydrophobic silica aerogel particles surface-modified with trimethylsilyl groups.

Hydrophobic silica aerogels that may be mentioned, for example, include the aerogel sold under the name VM-2260 (1NC1 name: Silica silylate), by the company Dow Coming, the particles of which have a mean size of about 1000 microns and a specific surface area per unit mass ranging from 600 to 800 m 2 /g. Mention may also be made of the aerogels sold by the company Cabot under the references Aerogel TLD 201, Aerogel OGD 201, Aerogel TLD 203, Enova® Aerogel MT 1100 and Enova Aerogel MT 1200.

The elastomeric polyorganosiloxanes are generally partially or totally crosslinked and possibly of three-dimensional structure. The elastomeric polyorganosiloxanes combined with a fatty phase are generally in the form of a gel constituted of an elastomeric organopolysiloxane combined with a fatty phase, included in at least one hydrocarbon-based oil and/or one silicone oil. They may be chosen especially from the crosslinked polymers described in patent application EP-A-0 295 886. According to said patent application, the elastomeric organopolysiloxanes are obtained by addition reaction and crosslinking of at least:

(a) one organopolysiloxane bearing at least two lower alkenyl groups per molecule;

(b) one organopolysiloxane bearing at least two hydrogen atoms linked to a silicon atom per molecule; and

(c) a platinum-type catalyst.

The hydrophobic thickener may be present in a content ranging from 0.05% to 10% by weight and preferably ranging from 0.1% to 8% by weight relative to the weight of the composition. COMMON ADDITIVES

The composition according to the invention may also comprise any common cosmetic ingredient that may be chosen especially from waxes, pasty compounds, additional moisturizers (also known as humectants), other than the abovementioned polyols, antioxidants, fragrances, menthol or menthol derivatives, preserving agents, neutralizers, sunscreens, sweeteners, vitamins, free-radical scavengers, sequestrants, salts (magnesium sulfate, sodium chloride), pH regulators, and mixtures thereof.

Needless to say, a person skilled in the art will take care to select the optional additional ingredients and/or the amount thereof such that the advantageous properties of the composition according to the invention are not, or are not substantially, adversely affected by the envisaged addition.

Another subject of the invention is a process for making up and/or caring for the lips, which consists in applying the composition according to the invention.

The composition according to the invention may be packaged in any type of device that is common in the field of fluid cosmetic compositions intended especially to be applied to the lips or the face (for instance the cheeks).

ft may thus be envisaged to use devices containing a container comprising an applicator equipped with a ball (roll-on), a container of dispensing pen type, terminated with an end provided with at least one orifice through which the composition may be expelled, or alternatively terminated with a felt or with a flocked tip, or with a brush; a container comprising a dip applicator, for instance a brush.

Such devices may or may not be provided with a mechanism for dispensing the composition making it possible to expel said composition from the container to the application member, or to the support. It should be noted that this mechanism may advantageously comprise a means for metering out the composition.

The examples which follow serve to illustrate the invention without, however, limiting the scope thereof.

EXAMPLE 1

The composition whose ingredients are listed in the table below is prepared (the percentages are expressed as weight of starting material, unless otherwise indicated).

Procedure

The sodium dehydroacetate is dissolved in the amodimethicone emulsion with stirring using a Rayneri blender.

At 50°C, the polysorbate 60 is added to the preceding mixture, with stirring using a Rayneri blender.

Once the mixture is homogeneous, it is allowed to cool with stirring.

At about 30°C, the Red 33 is then introduced into the mixture thus obtained, with continued stirring using a Rayneri blender.

Finally, the thickening polymer (Hostacerin AMPS) is added with stirring until the mixture has thickened and a homogeneous mixture is obtained.

The mixture of the silicone resin and the isododecane is then poured slowly into the mixture obtained previously while increasing the stirring speed, and the whole is left stirring for 10 minutes.

Evaluation of the composition

A creamy emulsion is obtained, which does not flow, and is homogeneous and stable.

The composition is easy to apply to the lips without running.

A thin, sparingly tacky, comfortable film which does not migrate into the fine lines and which does not stain the teeth is obtained.

The deposit obtained is fresh, sparingly tacky and has no sensation of dryness.

In addition, a glossy to very glossy deposit is obtained, for evaluation directly after application ft has good colour persistence on the lips and good gloss persistence.

Evaluation of the stability:

No phase separation or sedimentation of the particles is observed, if the composition comprises any, after storage in a closed bottle for one week, at 20°C.

Protocol for measuring the tack:

The composition is deposited in several stainless steel dishes 100 pm deep and is levelled off as quickly as possible. The dishes are left to dry at room temperature for one hour.

The apparatus used is a TACT2Ϊ texturometer. The clip mounted on the apparatus grips an AU4G cylinder 6 mm in diameter at the end of which is attached a smooth beige-coloured end piece made of synthetic skin, which has the same diameter and is 2 mm thick. The end piece is cleaned with ethanol between each measurement.

Several measurements are never taken at the same place of the deposit.

The parameters of the compression tests with maintenance over time are indicated below:

The tackiness is characterized by the separation force measured during the pressure reduction (pull phase), corresponding to the integral of the curve under the time axis. This force is expressed positively in joules per square metre.

EXAMPLE 3

The composition whose ingredients are listed in the table below is prepared (the percentages are expressed as weight of starting material, unless otherwise indicated):

I*) Preparation of the amodimethicone emulsion

450 g of fluid amino silicone (copolymer of dimethylsiloxane- aminomethylaminopropylmethylsiloxane bearing trimethylsilyl end groups, with an amine number of 7.2 mg of KOH/g and a viscosity of 5600 mPa.s at 25°C) are transferred into a first tank; 1800 g of dimethylsiloxane bearing trimethylsilyl end groups, with a viscosity of 61 500 mPa.s at 25°C, are added with stirring, and the stirring is continued for 2 hours at room temperature.

In a separate tank, 49 g of steareth-6 and 62 g of PEG100 stearate are mixed, and heated to 60°C. This temperature is maintained until a liquid mixture is obtained, and 31 g of trideceth-3 and 350 g of trideceth-lO (80% active material) are then added. The surfactant mixture has an HLB = 11.25. 80 g of water and 6.2 g of glacial acetic acid are added and stirring is continued until a creamy paste is obtained.

The contents of this second tank (creamy paste) are then transferred into the first tank (containing the silicones) and the mixture obtained is then mixed for 30 minutes at room temperature (20- 25°C). The mixing steps are performed to obtain a homogeneous mixture; they are performed at room temperature. 79.6 g of demineralized water are added and the mixture is stirred for 60 minutes.

72.7 g of demineralized water are added and the mixture is stirred for 50 minutes.

197.4 g of demineralized water are added and the mixture is stirred for 5 minutes.

294.3 g of demineralized water are added and the mixture is stirred for 5 minutes.

180 g of demineralized water are added and the mixture is stirred for 5 minutes.

180 g of demineralized water are added and the mixture is stirred for 5 minutes.

197.4 g of demineralized water are added and the mixture is stirred for 5 minutes.

197.4 g of demineralized water are added and the mixture is stirred for 3 minutes.

228.5 g of demineralized water are added and the mixture is stirred for 3 minutes.

Finally, 40.5 g of 2-phenoxyethanol (preserving agent) are added and the mixture is stirred for 3 minutes.

An oil- in- water emulsion with a particle size D50 of 170 nm is obtained.

Method for measuring the particle size

The size of the particles of the emulsion is measured using a ZetaSizer device from Malvern, UK, Nano-ZS model, based on the photon correlation spectroscopy (PCS) method.

The particle size D50 is measured when the evaluation algorithm is“cumulants analysis”. 0.5 g of the emulsion is placed in a 250 ml beaker, 100 ml of deionized water are added and the mixture is stirred so as to obtain the test solution. The test solution is placed in the measuring tank (or cell) and introduced into the measuring device.

The size D50 corresponds to the particle diameter value at 50% of cumulative distribution.

For example, if D50 = 170 nm, this means that 50% of the particles are greater than 170 nm in size and that 50% of the particles are less than 170 nm in size.

As a reminder, this distribution is on a volume basis.

Procedure

The sodium dehydroacetate is dissolved in the amodimethicone emulsion with stirring using a Rayneri blender.

The polysorbate 60 is dissolved at 50°C in the preceding mixture, with stirring using a Rayneri blender and the mixture is allowed to cool with stirring once dissolution has taken place.

At 30°C, the Red 33 is added to the preceding phase, with continued stirring using a Rayneri blender.

The silicone resin and isododecane are then poured slowly into the mixture obtained previously while increasing the stirring speed, and the whole is stirred for 10 minutes.

Evaluation of the composition

A creamy emulsion is obtained, which does not flow, and is homogeneous and stable.

A thin, sparingly tacky, comfortable film which does not migrate into the fine lines and which does not stain the teeth is obtained. The deposit obtained is fresh, glossy to very glossy, non-tacky and has no sensation of dryness.

It has good colour persistence on the lips and good gloss persistence.
