Title: MAKEUP AND/OR CARE COMPOSITION COMPRISING A VOLATILE SOLVENT, A PARTICULAR POLYESTER, AN ALKYLCELLULOSE AND A DYESTUFF, AND PROCESS USING SAME

The subject of the present invention is a makeup and/or care composition for the skin and/or lips, comprising a volatile solvent, a particular polyester, an alkylcellulose and a dyestuff, and also a makeup and/or care process for human keratin materials using same.

Many cosmetic makeup compositions containing dyestuffs, such as foundations, correctors, lipsticks or lip glosses, have been developed to improve the staying power and transfer resistance properties. Specifically, poor staying power may be reflected in particular by poor persistence of the colour (changing or fading) and/or of the gloss of the deposit. This consequently obliges the user to freshen the makeup more regularly than desired, which may be considered as time consuming.

Improving the staying power of compositions is obtained by means of compositions which form a film after application. Such compositions generally contain volatile solvents which evaporate on contact with the skin or the lips, leaving behind a layer comprising waxes and/or film-forming polymers, pigments and fillers. Film-forming polymers are synthetic polymers, usually silicone or acrylic polymers. Thus, mention may be made of the use of silicone resins, for instance trimethyl siloxysilicate (INCI name) or polypropylsilsesquioxane (INCI name) resins, or resins which comprise silicone polymers such as silicone acrylate dendrimer copolymers (acrylates/polytrimethyl siloxymethacrylate copolymer - INCI name). Acrylic polymers such as acrylic acid/isobutyl acrylate/isobornyl acrylate copolymers are also used. However, these compositions are often considered less comfortable, or even uncomfortable, from a sensory point of view for consumers.

Moreover, in recent years, consumers have become increasingly demanding regarding the composition of their cosmetic products and are in particular seeking to use products with a larger content of natural ingredients or ingredients of natural origin, ingredients whose environmental impact is minimized and/or ingredients that are compatible with a wide range of packaging.

The difficulty remains, however, in reconciling these latest trends with the fact that consumers do not, however, want to give up the very high performance to which they have become accustomed regarding the products they already use.

It has already been proposed, in makeup compositions of the prior art, to use liquid or pasty polyesters to obtain staying power properties.

Mention may notably be made of J P2002- 128623, JP2002-128628, JP2002-128629 and EP 1 604 634, which describe polyesters of dilinoleic diacids and dilinoleyl diol dimers having the INCI name Dimer Dilinoleyl Dimer Dilinoleate, such as those sold by the company Nippon Fine Chemical under the trade names Lusplan DD-DA5® and DD-DA7®. To obtain staying power properties in makeup compositions, it has also been proposed, in FR2931673, to use polyesters obtained by condensation of dimer and/or trimer of unsaturated fatty acids and of diol; in particular, the polyester obtained by condensation of dimer and/or trimer of unsaturated fatty acid and of diol is a polyester of dilinoleic acid and of 1 ,4-butanediol, such as the polymer sold by Biosynthis under the name Viscoplast 14436H® (INCI name: Dilinoleic Acid/Butanediol Copolymer).

It is also known practice, notably in FR 2 931 069, JP2005-325079 and JP2006-28129, to use polyesters of hydroxylated fatty acid triglyceride and of a saturated fatty diacid to provide staying power to makeup compositions. As examples of polyesters, mention may be made in particular of those having the INCI name Hydrogenated Castor Oil/Sebacic Acid Copolymer, such as the product sold under the name Crodabond CSA® by the company Croda, and also the hydrogenated castor oil dimer dilinoleate having the INCI name: Hydrogenated Castor Oil Dimer Dilinoleate, such as the product sold under the names Risocast-DA-L® and Risocast DA-H® by the company Kokyu Alcohol Kogyo.

However, it was found that liquid makeup compositions comprising the polyesters mentioned previously were not fully satisfactory and could lead to unsatisfactory film adhesion and makeup removal results. These polyesters can result, on application, in dewetting or in a film which runs between the two lips after the lips have been pressed together (blotting). Finally, it may occasionally be observed that the films break down into pieces on makeup removal.

The need remains to find novel compositions for making up and/or caring for the skin and/or the lips, based on a suitable polyester, leading to the production of a glossy deposit, with good staying power of the deposit and good transfer resistance properties, without the drawbacks mentioned previously.

It has unexpectedly been discovered that these objects may be achieved with a composition for making up and/or caring for the skin and/or lips, preferably the lips, notably comprising, in a physiologically acceptable medium:

A) at least one volatile solvent;

B) at least one polyester which is the product of reaction of components (i), (ii) and (iii) below:

(i) at least one polyglycerol-3;

(ii) at least one acid dimer; and

(iii) at least one fatty monoacid containing from 8 to 30 carbon atoms, components (i), (ii) and (iii) reacted being in a mole ratio of 1 mol of polyglycerol, 0.5 to 1 mol of acid dimer and 0.1 to 2.0 mol of fatty monoacid;

C) at least one alkylcellulose, the alkyl group of which is C2-C3, preferably ethylcellulose;

D) at least one dyestuff.

A subject of the invention is also a process for making up and/or caring for the skin and/or the lips, preferably the lips, which consists in applying the composition described previously. The composition according to the invention has the advantage of being stable over time and of being easy to apply, without dewetting on application or on blotting. Moreover, the deposit obtained is precise, homogeneous, not runny and sparingly or not at all tacky. The deposit does not migrate into the wrinkles and fine lines, in particular around the lips.

The resulting deposit is glossy, with improved staying power. It is also comfortable, without leaving a feeling of dryness or tautness.

DEFINITIONS

Since the composition according to the invention is a cosmetic composition, this means in particular that it comprises a physiologically acceptable medium, suitable for the nature of the support onto which the composition is to be applied, and also for the form in which the composition is to be packaged.

The term “physiologically acceptable” means compatible with the skin and/or the lips, which has a pleasant colour, odour and feel, and which does not cause any unacceptable discomfort (stinging or tautness) liable to discourage the consumer from using this composition.

The term “liquid composition” means any composition which has at least one of the following characteristics: i) it flows under its own weight at room temperature (20°C) and at atmospheric pressure (1.013 x 10 ⁵ Pa); ii) it is not solid at room temperature and at atmospheric pressure and a viscosity or consistency characterized by its hardness may be measured for same; iii) it does not have any particular shape such as that which can be obtained by hot casting in a mould or container of a given shape.

Such compositions may thus be found notably in fluid, creamy, pasty or gel form.

The term “polyester” means any polymer obtained by a condensation reaction of polycarboxylic acids with alcohols or polyols. Its macromolecular backbone contains the repetition of its ester function. The ester function denotes a characteristic group formed of an atom bonded simultaneously to an oxygen atom via a double bond and to an alkoxy group. When the bonded atom is a carbon atom, it is called a carboxylic ester, the general formula of which is R-COO-R’.

The term “polyglycerol-3” means triglycerol alone or a mixture of polyglycerols comprising at least triglycerol, and preferably triglycerol is predominant in said mixture.

Protocol for measuring the viscosity:

The viscosity measurement is generally performed at 25°C, using a Rheomat RM180 viscometer equipped with a No. 2, 3 or 4 spindle, the measurement being performed after 10 minutes of rotation of the spindle in the composition (after which time stabilization of the viscosity and of the spin speed of the spindle are observed), at a shear rate of 200 rpm.

According to one embodiment, the composition according to the invention may have, at 25°C, a viscosity of between 0.1 and 25 Pa.s, preferably between 0.2 and 20 Pa.s. Preferably, the viscosity at 25°C of a composition according to the invention may be between 0.2 and 10 Pa.s. In particular, the viscosity at 25°C of a composition according to the invention may be between 0.1 Pa.s (spindle 2) and 25 Pa.s (spindle 4), preferably between 0.2 Pa.s (spindle 2) and 20 Pa.s (spindle 4) and better still between 0.2 Pa.s (spindle 2) and 10 Pa.s (spindle 4).

The volatile oil(s) are chosen from apolar hydrocarbon-based oils and silicone oils, or mixtures thereof.

For the purposes of the invention, the term “volatile oil” refers to any oil that is capable of evaporating on contact with the skin in less than one hour, at room temperature and atmospheric pressure. The volatile oil is a volatile cosmetic compound, which is liquid at room temperature, notably having a non-zero vapour pressure, at room temperature and atmospheric pressure, notably having a vapour pressure ranging from 2.66 Pa to 40 000 Pa, in particular ranging from 2.66 Pa to 13 000 Pa and more particularly ranging from 2.66 Pa to 1300 Pa.

The term “apolar hydrocarbon-based oil” means an oil chosen from hydrocarbons, that is to say from compounds comprising only carbon and hydrogen atoms.

The term “silicone oil” denotes an oil comprising at least one Si-0 group, and more particularly an organopolysiloxane.

The apolar hydrocarbon-based volatile oils that may be used in the context of the invention are more particularly chosen from linear or branched, preferably saturated, oils containing from 6 to 16 carbon atoms, and mixtures thereof.

The volatile hydrocarbon-based oils that may be used in the compositions according to the invention may thus be chosen from volatile linear alkanes comprising from 6 to 14 carbon atoms.

Mention may also be made of the alkanes described in the Cognis patent applications WO 2007/068 371 or WO 2008/155 059 (mixtures of different alkanes differing by at least one carbon). These alkanes are obtained from fatty alcohols, which are themselves obtained from coconut kernel oil or palm oil.

The volatile hydrocarbon-based oils that may be used in the compositions according to the invention may be chosen from branched C8-C16 alkanes. Mention may notably be made of C8-C16 isoalkanes of petroleum origin (also known as isoparaffins), such as isododecane (also known as 2,2,4,4,6-pentamethylheptane), isodecane, isohexadecane and, for example, the oils sold under the Isopar® or Permethyl® trade names.

The composition according to the invention may optionally comprise water.

A water that is suitable for use in the invention may be a demineralized water, a floral water such as cornflower water and/or a mineral water such as Vittel water, Lucas water or La Roche Posay water and/or a spring water.

According to a particular embodiment of the invention, if the composition according to the invention comprises water, its content is less than 5% by weight, more particularly less than 2% by weight and preferably less than 0.5% by weight, relative to the total weight of the composition.

POLYESTER OF POLYGLYCEROL/ACID DIMER/MONOACID

The composition in accordance with the invention contains at least one polyester which is the product of reaction of components (i), (ii) and (iii) below:

(i) at least one polyglycerol-3;

(ii) at least one acid dimer; and

(iii) at least one fatty monoacid containing from 8 to 30 carbon atoms, components (i), (ii) and (iii) reacted being in a mole ratio of 1 mol of polyglycerol-3, 0.5 to 1 mol of acid dimer and 0.1 to less than 2.0 mol of fatty acid.

The polyesters of the invention and the synthesis thereof are described in patent applications US 2021/0259945, US 2021/0259946 and US 2021/0259930. According to a preferred embodiment, the amount of polyester active material ranges from 1% to 50% by weight, more preferentially from 3% to 20% by weight relative to the total weight of the composition.

According to a preferred embodiment, the polyester is a product of substantially or totally non-sequential reaction.

The term “product of substantially non-sequential reaction” means the product obtained by a substantially non-sequential reaction of the reactive components (i)-(iii).

The term “totally non-sequential reaction of the reactive components (i)-(iii)” means that the total content of each of the reagents (i)-(iii) to be made to react is added to the reaction vessel before starting the reaction.

In one embodiment of the present invention, the total content of each of the reagents (i)-(iii) to be made to react is added to the reaction vessel before starting the reaction, that is to say that the reaction is totally non-sequential, and the polymer is a product of totally nonsequential reaction of the components (i)-(iii). In other embodiments, 70-100%, or 75-100%, or 80-100%, or 85-100%, or 90-100%, or 95-100%, or 97-100% of each of the reagents (i)- (iii) are added to the reaction vessel before starting the reaction.

In one embodiment, the polyester is prepared by a one-step process which involves the introduction of all the reagents into a reaction vessel and the subsequent induction of an entirely random addition of the acid dimer and of isostearic acid to the polyglycerol-3.

Triglycerol has the formula H-[-OGIy]3-OH in which Gly designates a glycerol residue after removal of two hydroxyl groups.

Polvalvcerol-3

A polyglycerol-3 according to the invention in the form of a mixture of polyglycerols containing at least triglycerol also comprises polyglycerols which can be any product of oligocondensation of glycerol. They preferably correspond to formula (I) below: H[-O-Gly-]n-OH, in which each Gly is independently the residue of a glycerol molecule after removal of two hydroxyl groups; and n is a mean from 2 to 10.

Generally, the majority of the Gly groups are of the formula: -CH2-CHOH-CH2-, although residues comprising etherification at secondary or even tertiary hydroxyl groups are regarded as being within the scope of “Gly” and, consequently, may also be present.

Examples of polyglycerol-3 comprise diglycerol, triglycerol, tetraglycerol, pentaglycerol, hexaglycerol, heptaglycerol, octaglycerol, nonaglycerol, decaglycerol and mixtures thereof. In particular, preferential polyglycerols are those of formula (I) in which n in particular has a value from 2 to 7, more particularly from 2 to 5 and notably 2, 3 or 4, or mixtures of polyglycerols in these ranges.

Particularly appropriate examples of polyglycerol-3 comprise a mixture of polyglycerols having the following distribution, in which all the weight percentages are based on a total content of the polyglycerol-3 in the form of a mixture: - glycerol: 0% to 30% by weight, preferably 0% to 20% by weight, most preferably 0% to 15% by weight;

- diglycerol: 10% to 40% by weight, preferably 15% to 35% by weight, most preferably 20% to 32% by weight;

- triglycerol: 10% to 65% by weight, preferably 15% to 60% by weight, most preferably 18% to 55% by weight;

- tetraglycerol: 2% to 25% by weight, preferably 5% to 20% by weight, most preferably 8% to 20% by weight;

- pentaglycerol: 0% to 15% by weight, preferably 0% to 10% by weight, most preferably 0% to 5% by weight;

- hexaglycerol: 0% to 15% by weight, preferably 0% to 10% by weight, most preferably 0% to 5% by weight;

- heptaglycerol: 0% to 10% by weight, preferably 0% to 5% by weight, most preferably 0% to 3% by weight;

- octaglycerol: 0% to 10% by weight, preferably 0% to 5% by weight, most preferably 0% to 3% by weight;

- nonaglycerol: 0% to 5% by weight, preferably 0% to 3% by weight, most preferably 0% to 2% by weight;

- decaglycerol: 0% to 5% by weight, preferably 0% to 3% by weight, most preferably 0% to 2% by weight.

In one embodiment, the polyglycerol-3 comprises the following distribution of polyglycerols:

Glycerol: 0% to 30% by weight;

Diglycerol: 15% to 40% by weight;

Triglycerol: 10% to 55% by weight;

Tetraglycerol: 2% to 25% by weight;

Pentaglycerol and higher components: 0% to 15% by weight, all the weight percentages being based on a total content of polyglycerol-3 in the form of a mixture.

In one embodiment, the polyglycerol-3 is composed of at least 40% by weight, or of at least 45% by weight, or of at least 50% by weight, relative to the total weight of the polyglycerol-3, of a combination of diglycerol and of triglycerol.

In one embodiment, the polyglycerol-3 is composed of at least 20% by weight, or of at least 25% by weight, of diglycerol; at least 15% by weight, or at least 18% by weight, of triglycerol; at least 10% by weight, or at least 12% by weight, of tetraglycerol; in which all the weight percentages are based on a total content of the polyglycerol-3 in the form of a mixture.

A particularly preferred polyglycerol-3 comprises at least 25% by weight of diglycerol, at least 45% by weight of triglycerol and at least 10% by weight of tetraglycerol, relative to the total weight of the polyglycerol-3 in the form of a mixture. The analysis of such a polyglycerol-3 composition may be performed so as to determine its median or “mean” polyglycerol number. The above examples of polyglycerols with narrow and broad distributions can also be denoted as polyglycerol-3 because it is a matter of the integer closest to the mean and/or median.

Acid dimer

The acid dimer may be any dicarboxylic acid containing at least 4 carbon atoms. They may be linear or branched, for instance the dimers prepared from malonic acid, succinic acid, fumaric acid, dimethylglutaric acid or trimethyladipic acid, and from anhydrides thereof.

Fatty acid dimers are particularly useful. As is known, these are mixtures of acyclic and cyclic dicarboxylic acids which are obtained by a catalysed dimerization reaction of unsaturated fatty acids containing from 12 to 22 carbon atoms.

For the preparation and use of acid dimers and their physical and chemical properties, reference will be made to the publication “The Dimer Acids: The Chemical and Physical Properties, Reactions and Applications”, Ed. E.C. Leonard; Humko Sheffield Chemical, 1975, Memphis, Tenn.

The dicarboxylic acids may also contain, to a lesser extent, tri- and polyfunctional carboxylic acids. The functionality of the mixture must not exceed a mean molar value of 2.4.

The preferred acid dimers are typically derived from triglycerides rich in C18 ester groups, which can be hydrolysed to produce unsaturated C18 fatty monoacids. The starting materials may be derived from tallow oil and rapeseed oil but other natural sources, such as flax seeds, soybean, pumpkin and walnut, may be used. The target monoacids used in the reaction are rich in forms of oleic and linoleic acids which are described in the list of fatty acids contained below. Dimerization results mainly in the dimerization of unsaturated fatty acids, but trimers are also formed. After reaction, the product may be stored in the form of a mixture of reaction products or it may be further distilled or otherwise separated into molecular weight fractions. In one embodiment, the dimerization reaction produces a predominance (at least 60% by weight, more preferably at least 75% by weight) of acid dimer (C36 diacid) but also produces C54 acid trimers (less than 30% by weight, more preferably less than 25% by weight).

In one case, a standard acid dimer commercially available from Croda, Pripol 1025®, which contains 72% by weight of acid dimer and 19% by weight of acid trimer, is used.

In another case, a standard hydrogenated acid dimer from Oleon, Radiacid 0960®, which contains 87% by weight of acid dimer and 10% by weight of acid trimer, is used. In both cases, the polymer as described is characterized by a higher molecular weight, a more hydrophobic nature and a higher viscosity than those which can be provided by pure diacids of lower molecular weight. The presence of acid trimer further improves the molecular weight and the performance qualities of these polymers.

In one embodiment, the copolymer of the present invention is prepared from at least one hydrogenated acid dimer. In another embodiment, the polymer is prepared from a hydrogenated acid dimer comprising hydrogenated dimerized C18 fatty acids, which hydrogenated acid dimer is obtained by dimerization of unsaturated C18 fatty acids and subsequent hydrogenation.

In one embodiment, the hydrogenated acid dimer contains a content of acid trimer ranging from about 5% to 25% by weight, based on the total weight of hydrogenated acid dimer.

In another embodiment, the hydrogenated acid dimer contains a predominance (at least 60% by weight, more preferentially at least 75% by weight, but not more than 95% by weight, or better still not more than 90% by weight, or even better still not more than 85% by weight) of hydrogenated acid dimer (C36 diacid) and also contains hydrogenated C54 acid trimers (less than 30% by weight, more preferably less than 25% by weight, but more than 5% by weight, more preferably more than 10% by weight).

C8-C30 fatty monoacid

The C8-C30 fatty monoacids may include natural or refined fatty acids, such as hydrolysed rapeseed oil, hydrolysed sunflower oils, and the like, but these contain both lower and higher MW chains. Useful fatty monoacids may be linear, branched, saturated, unsaturated and aromatic materials with an acidity provided by carboxylic acid fractions.

Acids that are suitable for use in the invention comprise caprylic acid (C8), pelargonic acid (C9), capric acid (C10), undecylic acid (C11), lauric acid (C12), tridecylic acid (C13), myristic acid (C14), pentadecylic acid (C15), palmitic acid (C16), margaric acid (C17), stearic acid (C18), isostearic acid (C18), nonadecylic acid (C19), arachidic acid (C20), behenic acid (C22) and lignoceric acid (C24).

The comparison of stearic acid and isostearic acid shows that the branching leads to an elevated melting point and results in a low viscosity at room temperature for isostearic acid, compared to a solid material for stearic acid. This lower viscosity can be useful in the handling of starting materials and also to make it possible for the esters manufactured with this acid to retain their liquid properties. Branched-chain fatty acids often contain a single methyl branch along the linear carbon chain and are produced in nature by microbial action. Isostearic acid is available as a reaction by-product in the creation of the acid dimer described above.

Another way to obtain a liquid product consists in using unsaturated, linear and branched, fatty monoacids. These unsaturated acids may include palmitoleic acid (C16:1), vaccenic acid (C18:1), oleic acid (C18:1), elaidic acid (C18:1), linoleic acid (C18:2), linolelaidic acid (C18: 2), a-linolenic acid (C18:3), y-linolenic acid (C18:3), stearidonic acid (C18:4), paullinic acid (C20:1), gondoic acid (C20:1), dihomo-y-linolenic acid (C20:3), mead acid (C20:3), arachidonic acid (C20:4), eicosapentaenoic acid (C20:5), erucic acid (C22:1), docosatetraenoic acid (C22:4), cervonic acid (C22:6) and nervonic acid (C24:1). As is well known to a person skilled in the art, the designation means that the length of the carbon chain is X carbon atoms and that there are Y double bonds in the chain. In one embodiment, isostearic acid will be preferred.

In a particularly preferred embodiment, the polyester of the invention is a product of substantially or totally non-sequential reaction of the following components:

(i) at least one polyglycerol-3 comprising at least 25% by weight of diglycerol, at least 45% by weight of triglycerol and at least 10% by weight of tetraglycerol, in each case relative to the total weight of polyglycerol-3 in the form of a mixture;

(ii) at least one hydrogenated acid dimer containing at least 60% by weight of hydrogenated C36 diacid and from 5% to 25% by weight of hydrogenated C54 triacid, in each case relative to the total weight of hydrogenated acid; and iii) isostearic acid.

In one embodiment, the polyester is prepared by a one-step process which involves the introduction of all the reagents into a reaction vessel and the subsequent induction of an entirely random addition of the acid dimer and of isostearic acid to the polyglycerol-3.

In one embodiment, it is preferable to have a total degree of esterification of the available polyglycerol hydroxyl fragments (total esterification) of from 24% to 74% and a degree of esterification of the available polyglycerol hydroxyl fragments by an acid dimer alone (esterification with an acid dimer) of from 20% to 40%. Even more importantly, the degree of esterification by end-cap units (esterification with a monoacid) is also defined in this description and it is important to maintain the esterification with a monoacid from 4% to 40%.

It is preferable to have a total esterification of 28% to 57% with an esterification with an acid dimer of 20% to 30% and an esterification with a monoacid of between 8% and 27%.

It is even more preferable to have a total esterification of 33% to 48% with an esterification with an acid dimer of 20% to 28% and an esterification with a monoacid of between 13% and 20%.

It is even more preferable to have a total esterification of 24% to 74% with an esterification with a hydrogenated acid dimer of 20% to 40% and an esterification with a monoacid of between 4% and 40%.

It is even more preferable to have a total esterification of 28% to 57% with an esterification with a hydrogenated acid dimer of 20% to 30% and an esterification with a monoacid of between 8% and 27%.

It is also even more preferable to have a total esterification of about 40% with an esterification with a hydrogenated acid dimer of about 20% and an esterification with a monoacid of about 20%.

It is also even more preferable to have also most preferably a total esterification of about 40% with an esterification with a hydrogenated acid dimer of about 27% and an esterification with a monoacid of about 13%.

In one embodiment, the reacted components are in a mole ratio of 1 mol of polyglycerol- 3, 0.5 to 1 mol of acid dimer and 0.2 to 1.7 mol of fatty acid. In another embodiment, the reacted components are in a mole ratio of 1 mol of polyglycerol-3, 0.5 to 0.75 mol of acid dimer and 0.4 to 1 .35 mol of isostearic acid.

In another embodiment, the reacted components are in a mole ratio of 1 mol of polyglycerol-3, 0.5 to 0.7 mol of acid dimer and 0.65 to 1 mol of isostearic acid.

In another embodiment, the reacted components are in a mole ratio of 1 mol of polyglycerol-3, 0.5 to 1 mol of hydrogenated acid dimer and 0.2 to 1.7 mol of isostearic acid.

In another embodiment, the reacted components are in a mole ratio of 1 mol of polyglycerol-3, 0.5 to 0.75 mol of hydrogenated acid dimer and 0.4 to 1.35 mol of isostearic acid.

In a particularly preferred embodiment, the reacted components are in a mole ratio of

1 mol of polyglycerol-3, 0.5 mol of hydrogenated C36 acid dimer and 1 mol of isostearic acid.

By adjusting the mole ratio of the termination of the fatty acids and by balancing the amount of polyglycerol-3 and of acid dimer, it is also possible to control the degree of acid dimer-polyglycerol extension and termination so that crosslinking, for example, via the acid trimer, results in much higher viscosities.

The target viscosity of the pure polymer must be greater than 50 000 mPa.s and less than 5 000 000 mPa.s at 25°C.

In one preferred embodiment, the target viscosity is > 75 000 mPa.s and < 2 500 000 mPa.s at 25°C.

In another preferred embodiment, the target viscosity is > 100 000 mPa.s and <

2 000 000 mPa.s at 25°C.

In a most preferred embodiment, the target viscosity is > 1 000 000 mPa.s and < 2 000 000 mPa.s at 25°C.

The viscosity is measured using an MCR3O2® rheometer from Anton Paar Inc. Rough or smooth twin flat plates 50 mm in diameter were used, covered with a polymer sample, adjusted to a gap of 0.5 to 1 mm, and temperature and shear rate scans were performed. The polyesters of the invention have Newtonian behaviour and thus have a constant viscosity over a wide range of shear rates. In addition, the polymers of the present description demonstrated a reduced viscosity with temperature. Thus, the viscosity measurements are reported at a precisely controlled temperature and generally in the form of a shear rate of 1 . The values are reported in mPa.s.

The polyesters of the invention are characterized by weight-average molecular masses > 2500 Da and < 1 000 000 Da, measured by GPC using linear polystyrene standards.

The GPC column used for these tests consisted of: Phenolgel, 300 x 4.6 mm; a continuous tetrahydrofuran (THF) phase was used and injected at 0.35 ml/min, column oven maintained at 40°C; a 50 pl injection and a Wyatt Ri refractive index detector. The calibration standards used were strictly linear polystyrene intended to be monodispersed. The narrow range polystyrene GPC calibration standards were prepared as a mobile phase and had maximum molecular weights of 1 290000 Da, 560000 Da, 65500 Da, 28500 Da, 10 100 Da, 1680 Da, 580 Da and 208 Da. Using standard methodologies, the weight- and numberaverage molecular mass is automatically calculated with standard GPC software.

In a preferred embodiment, the polyesters described have a weight-average molecular weight > 4000 Da and < 250 000 Da, measured by GPC using linear polystyrene standards. In a most preferred embodiment, the polymers described have a weight-average molecular weight > 5000 Da and < 150 000 Da, measured by GPC using linear polystyrene standards.

In yet another embodiment, the polyester of the invention has a combination of weightaverage molecular mass > 5000 Da and < 150 000 Da, measured by GPC using linear polystyrene standards, and of viscosity at 25°C > 100 000 mPa.s and < 2 000 000 mPa.s.

In a preferred embodiment, the polyester of the invention is a product of substantially or totally non-sequential reaction of the following components:

(i) at least one polyglycerol-3 comprising at least 25% by weight of diglycerol, at least 45% by weight of triglycerol and at least 10% by weight of tetraglycerol, in each case relative to the total weight of polyglycerol-3 in the form of a mixture;

(ii) at least one hydrogenated acid dimer containing at least 60% by weight of hydrogenated C36 diacid and from 5% to 25% by weight of hydrogenated C54 triacid, in each case relative to the total weight of hydrogenated acid; and

(iii) isostearic acid; in which the polymer has a combination of weight-average molecular mass > 5000 Da and < 15 000 Da, measured with GPC using linear polystyrene standards, and of viscosity of the pure polymer > 100 000 mPa.s and < 2 000 000 mPa.s at 25°C; and in which the copolymer is also characterized by a total esterification of about 40%, an esterification with a hydrogenated acid dimer of about 27% and an esterification with a monoacid of about 13%.

In practice, given that the raw ingredients contain a range of polyglycerol units and a range of acid dimer and trimer contents, the above numbers can be adjusted using the actual (and not theoretical) hydroxyl fractions and carboxylic acid fractions, as are determined by methods such as mass spectrometry, NMR and liquid chromatography. The above esterification ranges are based on the ideal structure of the polyglycerol-3 and of the C36 acid dimer. The actual ranges may thus be slightly different from the values indicated above and may be calculated on the basis of these analytical values.

It is more practical to define the extent of the polymerization by the final acid number. The initial acid numbers, in the light of the distribution of the polyglycerol, monoacid and polyacid fractions present, can be reliably calculated using the actual acid number determined by the raw ingredient used.

For example, the initial total acid number (“AV”, which is commonly defined in mg of KOH/g of total reagent), is 135 AV. This comprises 68 AV for the acid dimer and 67 AV for the isostearic acid for a preferred embodiment containing 1 mol of polyglycerol-3, 0.5 mol of hydrogenated C36 acid dimer and 1 mol of isostearic acid. All the preferred ratio embodiments described above have a corresponding initial AV which can be calculated. When, during the polymerization reaction, the AV units are reduced, this ratio gives the percentage of conversion of the reaction from the total initial reactive acid fractions to the final residual acid fractions.

Thus, the degree of completion of the reaction is defined by (1 - final AV) I initial AV.

In one embodiment, the polyesters of the invention have final acid numbers of from 0.1 to < 25 mg of KOH/g of polymer.

In a preferred embodiment, the polyesters of the invention have final acid numbers of from 0.1 to < 10 mg of KOH/g of polymer.

In a most preferred embodiment, the polyesters of the invention have final acid numbers of from 0.1 to < 5 mg of KOH/g of polymer.

As the degree of completion of the reaction is defined by the equation 1- final AV/initial AV, the degree of completion of the reaction of such mixtures to give final polymer is > 80%.

In a preferred embodiment, the degree of completion of the reaction of such mixtures to give final polymer is > 90%.

In a most preferred embodiment, the degree of completion of the reaction of such mixtures to give final polymer is > 95%.

In a preferred embodiment, the polyester of the invention is a product of reaction of a polyglycerol-3, of a hydrogenated C36 acid dimer and of isostearic acid in a mole ratio of 1/0.5/1 , as described in Example 10 (copolymer) of US 2021/0259945.

The sizes are measured by static light scattering using a commercial MasterSizer 3000® particle size analyser from Malvern, which makes it possible to determine the particle size distribution of all of the particles over a wide range which may extend from 0.01 pm to 1000 pm. The data are processed on the basis of the standard Mie scattering theory. This theory is the most suitable for size distributions ranging from submicronic to multimicronic; it makes it possible to determine an “effective” particle diameter.

COSMETIC ADDITIVES

The compositions according to the invention may also include additives commonly used in skincare and/or makeup products, such as active agents such as vitamins, for example vitamins A, E, C and B3, adenosine, hyaluronic acid and salts thereof; UV-screening agents; fillers; waxes; pasty compounds; hydrophilic gelling agents; film-forming agents other than alkylcellulose (in particular ethylcellulose); lipophilic gelling agents; fragrances; preserving agents; and mixtures thereof.

It is a matter of routine practice for a person skilled in the art to adjust the nature and amount of the additives present in the compositions in accordance with the invention such that the desired cosmetic properties thereof are not thereby affected.

Fillers

The compositions in accordance with the invention may thus comprise at least one filler, notably making it possible to give them additional properties in terms of improved mattness, coverage, staying power and/or stability.

The term “filler” should be understood as meaning colourless or white solid particles of any shape which are provided in an insoluble form and dispersed in the medium of the composition. These particles give body or rigidity to the composition and/or softness and uniformity to the makeup.

The fillers may be mineral or organic.

Preferably, they may be chosen from natural fillers or fillers of natural origin.

The term “natural compound” means a compound that is obtained directly from the earth or the soil, or from plants or animals, via, where appropriate, one or more physical processes, for instance milling, refining, distillation, purification or filtration.

The term “compound of natural origin” means 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 non-limiting examples of additional chemical or industrial treatments bringing about modifications which do not affect the essential qualities of a natural compound, mention may be made of those permitted by the controlling bodies, such as Ecocert (Reference system for biological and ecological cosmetic products, January 2003), or defined in handbooks recognized in the field, such as “Cosmetics and Toiletries Magazine”, 2005, volume 120, 9:10.

The fillers used in the compositions according to the present invention may be in lamellar, globular or spherical form, in the form of fibres or in any other intermediate form between these defined forms. The fillers according to the invention may or may not be surface-coated, and in particular they may be surface-treated with amino acids or any other substance that promotes the dispersion and compatibility of the filler in the composition.

Preferably, the filler(s) are present in the composition in a content ranging from 0.5% to 20% by weight, preferably from 1 % to 15% by weight, more particularly from 3% to 10% by weight, relative to the total weight of the composition.

Waxes

The composition according to the invention may comprise at least one wax.

For the purposes of the present invention, the term “wax” means a lipophilic compound, which is solid at room temperature, with a reversible solid/liquid change of state, which has a melting point of greater than or equal to 30°C that may be up to 120°C.

For the purposes of the invention, the melting point corresponds to the temperature of the most endothermic peak observed on thermal analysis (DSC) as described in the standard ISO 11357-3; 1999. The melting point of the wax may be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name DSC Q2000 by the company TA Instruments with the TA Universal Analysis software.

The measuring protocol is as follows:

A sample of 5 mg of wax placed in a crucible is subjected to a first temperature rise ranging from -20°C to 120°C, at a heating rate of 10°C/minute, it is then cooled from 120°C to -20°C at a cooling rate of 10°C/minute and is finally subjected to a second temperature rise ranging from -20°C to 120°C at a heating rate of 5°C/minute.

During the second temperature rise, the melting point of the solid fatty substance is measured, which corresponds to the temperature of the most endothermic peak observed of the melting curve, representing the variation in the difference in power absorbed as a function of the temperature.

The enthalpy of fusion of the wax (AHf), corresponding to the integral of the entire melting curve obtained, may also be measured. This enthalpy of fusion of the wax is the amount of energy required to cause the compound to change from the solid state to the liquid state. It is expressed in J/g.

The waxes may be silicone waxes and, preferably, hydrocarbon-based waxes. They are also of plant, mineral, animal and/or synthetic origin.

In particular, the waxes have a melting point preferably greater than or equal to 35°C and better still greater than or equal to 40°C.

Apolar waxes:

For the purposes of the present invention, the term “apolar hydrocarbon-based wax” means a wax consisting solely of carbon and hydrogen atoms and free of heteroatoms, for instance N, O, Si, P, etc.

It may thus contain alcohol, ester, ether, carboxylic acid, amine and/or amide groups.

The term “silicone wax” means an oil comprising at least one silicon atom and notably comprising Si-0 groups.

The wax content, if the composition comprises any, advantageously ranges from 1% to 20% by weight, in particular from 5% to 15% by weight, relative to the total weight of the composition.

Pasty compounds

The composition according to the invention may also comprise at least one compound which is pasty at room temperature and atmospheric pressure.

For the purposes of the present invention, the term “pasty” refers to a lipophilic compound with a reversible solid/liquid change of state, notably having in the solid state an anisotropic crystal organization, and comprising at room temperature a liquid fraction and a solid fraction.

In other words, the starting melting point of the pasty compound may be lower than room temperature. The liquid fraction of the pasty compound, measured at room temperature, may represent 9% to 97% by weight of the pasty compound. This fraction that is liquid at room temperature preferably represents between 15% and 85%, more preferably between 40% and 85%, by weight.

The melting point of the pasty fatty substance is determined according to the same principle as that described in detail previously for the waxes.

In the case of a pasty compound, the measurement protocol is, however, as follows:

A sample of 5 mg of pasty fatty substance placed in a crucible is subjected to a first temperature rise passing from -20°C to 100°C, at a heating rate of 10°C/minute, it is then cooled from 100°C to -20°C at a cooling rate of 10°C/minute and it is finally subjected to a second temperature rise passing from -20°C to 100°C at a heating rate of 5°C/minute.

The melting point of the pasty fatty substance is the value of the temperature corresponding to the top of the peak on the curve representing the variation in the difference in power absorbed as a function of the temperature.

It should be noted that the liquid fraction by weight of the pasty fatty substance at room temperature is equal to the ratio of the heat of fusion consumed at room temperature to the heat of fusion of the pasty fatty substance.

The heat of fusion of the pasty fatty substance is the heat consumed by said substance in order to pass from the solid state to the liquid state. The pasty fatty substance is said to be in the solid state when all of its mass is in crystalline solid form. The pasty fatty substance is said to be in the liquid state when all of its mass is in liquid form.

The heat of fusion of the pasty fatty substance is the amount of energy required to make the pasty fatty substance change from the solid state to the liquid state. It is expressed in J/g. The heat of fusion of the pasty fatty substance is equal to the area under the curve of the thermogram obtained.

The pasty compound may in particular be chosen from synthetic pasty compounds and fatty substances of plant origin.

Comparative Example 1b is of identical composition except that the polyester is replaced with the same content of Hydrogenated Castor Oil Dimer Dilinoleate.

The compositions are detailed in the table below.

[Table 1]

Composition preparation method:

A portion of the isododecane, the alcohol and the polyester (SolAmaze, Softisan or Risocast) were mixed in a beaker. The mixture was stirred with a Rayneri flocculator at 500 rpm for 2 minutes.

The ethylcellulose was introduced as a fine mist while stirring with the deflocculator at 500 rpm (into the vortex) and the mixture was then left stirring for 10 minutes.

The pigment, ground beforehand using a three-roll mill, was added with the remaining isododecane.

Evaluation of the compositions:

Protocol for evaluating the staying power

Each composition was applied to an Erichsen contrast chart, using a spreader, as a deposit with a thickness of 24.5 pm, over a width of at least 6 cm, and was left to dry on a hotplate at 32°C for 40 minutes.

Three thin strips of Wypall® fabric (Kimberley Clark) of 2 cm were placed on the deposit without them overlapping:

* the first strip is dry,

* the second strip is impregnated with distilled water (0.1 ml),

* the third strip is impregnated with olive oil (0.1 ml).

The film spreader weighted with a weight of 2 kg was placed on all of the thin strips, and the assembly was moved over the film.

The state of the deposit was observed.

The operation was repeated for each of the compositions prepared.

Grading of the staying power
