Description

Title of the invention: Composition comprising a polyester and a lipophilic silicone polymer technical field

[0001] The present invention relates to a cosmetic composition comprising a particular polyester and a lipophilic silicone polymer. It also relates to a method for the care or makeup of keratinous materials using the composition. Previous technique

[0002] Makeup or skincare products, such as foundations, eyeliners, lipsticks, or eyelash products like mascaras, generally contain fatty substances, such as oils, waxes, pigments, and / or fillers. When applied to the skin or eyelashes, these compositions leave a film that does not always offer good resistance to water, during swimming or showering, and / or to tears, perspiration, sebum, or friction from fingers or clothing. The film is thus weakened, and the makeup no longer lasts.

[0003] On the other hand, these compositions also have the disadvantage of transferring, that is, of settling at least partially, leaving traces on certain surfaces with which they may come into contact, including a glass, a cup, a cigarette, clothing, or skin. This results in poor longevity of the applied film, requiring regular reapplication of the makeup. Furthermore, the appearance of unacceptable traces, particularly on blouse collars, may deter some women from using this type of makeup.

[0004] To improve holding properties, it is known to use lipophilic silicone polymers such as silicone resins like trimethylsiloxysilicates, or silicone acrylates such as the acrylate / polytrimethylsiloxymethacrylate copolymer sold under the reference DOWSIL® FA 4002 ID silicone acrylate by the Dow company.

[0005] However, consumers are increasingly looking for products whose ingredients are natural or of natural origin, without giving up the performance they are used to with the products used. Description of the invention

[0006] The present invention therefore aims to provide a composition that does not have the above disadvantages and leads to the formation of a film with good non-transfer properties, particularly when dry and in the presence of oil, and good adhesion, while reducing the silicone compound content as much as possible.

[0007] The applicant has surprisingly discovered that the combination of a particular polyester, a lipophilic silicone polymer, and a volatile alkane, as defined below, makes it possible to obtain a film with good adhesion and good non-transfer properties. The film does not transfer, or transfers very little, when dry or in the presence of oil. This combination also makes it possible to reduce the content of silicone products, particularly the lipophilic silicone polymer, and even to eliminate the need for volatile silicone oils. Summary of the invention

[0008] More specifically, the present invention relates to a composition comprising, in a physiologically acceptable medium,

[0009] a) a polyester that is the reaction product of the following components (i), (ii) and (iii): (i) at least one polyglycerol-3 (ii) at least one dimeric acid, and (iii) at least one fatty acid mono-compound having from 8 to 30 carbon atoms, the components (i), (ii) and (iii) reacted being in a molar ratio of 1 mole of polyglycerol-3, from 0.5 to 1 mole of dimer acid and from 0.1 to less than 2.0 moles of fatty acid mono-compound,

[0010] b) a lipophilic silicone polymer,

[0011] said polyester and said lipophilic silicone polymer being present in a weight ratio polyester / lipophilic silicone polymer ranging from 0.25 to 6.9.

[0012] The invention also relates to a method for the care and / or makeup of keratinous materials, comprising the application to said keratinous materials of a composition as defined above. Detailed description

[0013] Advantageously, said polyester and said lipophilic silicone polymer may be present in the composition according to the invention in a weight ratio polyester / lipophilic silicone polymer ranging from 0.5 to 6, and preferably ranging from 0.5 to 5, preferably ranging from 0.75 to 4.

[0014] POLYGLYCEROL-3 POLYESTER / DIMER ACID / FATTY MONO ACID

[0015] The composition according to the invention comprises a polyester which is the reaction product of the following components (i), (ii) and (iii): (i) at least one polyglycerol-3; (ii) at least one dimeric acid; and (iii) at least one mono-fatty acid having from 8 to 30 carbon atoms, the components (i), (ii) and (iii) reacted being in a molar ratio of 1 mole of polyglycerol-3, 0.5 to 1 mole of dimer acid and from 0.1 to less than 2.0 moles of fatty acids.

[0016] The term "polyester" refers to any polymer obtained by the condensation reaction of polycarboxylic acids with alcohols or glycols. Its macromolecular skeleton contains a repeating ester functional group. The ester functional group is a characteristic group formed by an atom bonded simultaneously to an oxygen atom by a double bond and to an alkoxy group. When the bonded atom is a carbon atom, it is called a carboxylic ester, whose general formula is R-COO-R'.

[0017] By "polyglycerol-3" is meant triglycerol alone or a mixture of polyglycerols comprising at least triglycerol, and preferably triglycerol is the major component in said mixture.

[0018] The polyesters of the invention are described together with their synthesis in US patent applications 2021 / 0259945, US 2021 / 0259946 and US 2021 / 0259930 in the name of Nouryon.

[0019] According to a preferred embodiment, the polyester is a substantially or totally non-sequential reaction product.

[0020] By "substantially non-sequential reaction product", we mean the product obtained by a substantially non-sequential reaction of the reactive components (i)-(iii).

[0021] By "totally non-sequential reaction of the reactant components (i)-(iii)", it is meant that the total content of each of the reactants (i)-(iii) to be reacted is added to the reaction vessel before starting the reaction.

[0022] In one embodiment of the present invention, the total content of each of the reactants (i)-(iii) to be reacted is added to the reaction vessel before the reaction begins, i.e., the reaction is completely non-sequential, and the polymer is a completely non-sequential reaction product of 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 reactants (i)-(iii) are added to the reaction vessel before the reaction begins.

[0023] In one embodiment, the polyester is prepared by a one-step process which involves introducing all the reactants into a reaction vessel and then inducing a fully statistical addition of the dimer acid and the mono-fatty acid to polyglycerol-3. Polyglycerol-3

[0024] Triglycerol has the formula H-[-OGly]3-OH in which Gly designates a remainder of glycerol after the removal of two hydroxyl groups.

[0025] A polyglycerol-3 according to the invention in the form of a mixture of polyglycerols containing at least triglycerol comprises polyglycerols that may be any which oligocondensation product of glycerol. They preferably correspond to formula (I): H[-O-Gly-]n-OH, in which each Gly is independently the residue of a glycerol molecule after the removal of two hydroxyl groups; and n is an average of 2 to 10.

[0026] Generally, most Gly groups are of the formula: -CH2-CHOH-CH2 -, although residues including etherification at the level of secondary or even tertiary hydroxyl groups are considered to be within the framework of "Gly" and, consequently, may also be present.

[0027] Examples of polyglycerol-3 in mixture form include diglycerol, triglycerol, tetraglycerol, pentaglycerol, hexaglycerol, heptaglycerol, octaglycerol, nonaglycerol, decaglycerol, and mixtures thereof. In particular, preferred polyglycerols are those of formula (I) in which n is in particular from 2 to 7, more particularly from 2 to 5, and especially 2, 3, or 4, or mixtures of polyglycerols in these ranges.

[0028] Particularly suitable examples of polyglycerol-3 include a mixture of polyglycerols having the following distribution in which all weight percentages are based with respect to the total weight of polyglycerol-3 in mixture form. - glycerol: 0 to 30% by weight, preferably 0 to 20% by weight, preferably 0 to 15% by weight; - diglycerol: 10 to 40% by weight, preferably 15 to 35% by weight, preferably 20 to 32% by weight; - triglycerol: 10 to 65% by weight, preferably 15 to 60% by weight, preferably 18 to 55% by weight; - tetraglycerol: 2 to 25% by weight, preferably 5 to 20% by weight, preferably 8 to 20% by weight; - pentaglycerol: 0 to 15% by weight, preferably 0 to 10% by weight, preferably 0 to 5% by weight; - hexaglycerol: 0 to 15% by weight, preferably 0 to 10% by weight, preferably 0 to 5% by weight; - heptaglycerol: 0 to 10% by weight, preferably 0 to 5% by weight, preferably 0 to 3% by weight; - octaglycerol: 0 to 10% by weight, preferably 0 to 5% by weight, preferably 0 to 3% by weight; - nonaglycerol: 0 to 5% by weight, preferably 0 to 3% by weight, preferably 0 to 2% by weight; - decaglycerol: 0 to 5% by weight, preferably 0 to 3% by weight, preferably 0 to 2% by weight.

[0029] In one embodiment, a polyglycerol-3 in mixture form comprises the following polyglycerol distribution: 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 relative to the total weight of polyglycerol-3 as a mixture.

[0030] In one embodiment, a polyglycerol-3 in mixture form is composed of at least 40% by weight, or at least 45% by weight, or at least 50% by weight, of a combination of diglycerol and triglycerol relative to the total weight of the polyglycerol-3 in mixture form.

[0031] In one embodiment, a polyglycerol-3 is composed of at least 20% by weight, or 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; wherein all the weight percentages are relative to the total weight of the polyglycerol-3 in mixture form.

[0032] 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 mixture form.

[0033] Analysis of such a polyglycerol-3 composition can be performed to determine its median or "mean" polyglycerol number. The examples of polyglycerols above with narrow and broad distributions can also be designated as polyglycerol-3, since this is the integer closest to the mean and / or median. Dimer acid

[0034] The dimeric acid can be any dicarboxylic acid having at least 4 carbon atoms. They can be linear or branched, such as for example the dimers prepared from malonic acid, succinic acid, fumaric acid, dimethylglutaric acid or trimethyladipic acid, and their anhydrides.

[0035] Dimeric fatty acids are particularly useful. As is known, they are mixtures of acyclic and cyclic dicarboxylic acids obtained by a catalyzed dimerization reaction of unsaturated fatty acids having 12 to 22 carbon atoms.

[0036] For the preparation and use of dimer acids 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. EC Leonard; Humko Sheffield Chemical, 1975, Memphis, Tenn.

[0037] Dicarboxylic acids may also contain, to a lesser extent, tri- and polyfunctional carboxylic acids. The functionality of the mixture should not exceed an average molar value of 2.4.

[0038] Preferred dimeric acids are typically derived from triglycerides rich in Cl8 ester groups, which can be hydrolyzed to produce C18 unsaturated mono-fatty acids. Raw materials can be derived from tallow oil and rapeseed oil, but other natural sources such as flaxseed, soybeans, pumpkin seeds, and walnuts can be used. The target mono-acids used in the reaction are rich in the forms of oleic and linoleic acids described in the fatty acid list below. Dimerization leads primarily to the dimerization of unsaturated fatty acids, but trimers are also formed. After the reaction, the product can be stored as a mixture of reaction products or it can be further distilled or otherwise separated into molecular weight fractions.In one embodiment, the dimerization reaction produces a majority (at least 60% by weight, more preferably at least 75% by weight) of dimeric acid (C36 diacid) but also produces C54 trimer acids (less than 30% by weight, more preferably less than 25% by weight).

[0039] In one case, a standard dimeric acid commercially available from Croda, Pripol 1025®, is used, which contains 72% by weight of dimer and 19% by weight of trimer acid.

[0040] In another case, a standard hydrogenated dimeric acid from Oleon, Radiacid 0960®, is used, which contains 87 wt% dimer and 10 wt% trimeric acid. In both cases, the polymer as described is characterized by a higher molecular weight, greater hydrophobicity, and higher viscosity than those that can be provided by pure diacids of lower molecular weight. The presence of trimeric acid further improves the molecular weight and performance of these polymers.

[0041] In one embodiment, the copolymer of the present invention is prepared from at least one hydrogenated dimeric acid.

[0042] In another embodiment, the polymer is prepared from a hydrogenated dimeric acid comprising hydrogenated dimerized C18 fatty acids, which hydrogenated dimeric acid is obtained by dimerization of unsaturated Cl8 fatty acids and subsequent hydrogenation.

[0043] In one embodiment, the hydrogenated dimer acid contains a trimer acid content ranging from about 5 to 25% by weight, based on a total weight of hydrogenated dimer acid.

[0044] In another embodiment, the hydrogenated dimeric acid contains a majority (at least 60% by weight, more preferably at least 75% by weight, but at most 95% by weight, or better yet at most 90% by weight, or even better at most 85% by weight) of hydrogenated dimeric acid (C36 diacid) and also contains hydrogenated C54 trimer acids (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). Fatty acid monoacid

[0045] C8-C30 mono-fatty acids can include natural or refined fatty acids, such as hydrolyzed rapeseed oil, sunflower oils, etc., but these contain both lower and higher molecular weight chains. Useful mono-fatty acids can be linear, branched, saturated, unsaturated, and aromatic, with acidity provided by carboxylic acid fractions.

[0046] Acids suitable for the invention include 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), nonadecyl acid (C19), arachidic acid (C20), behenic acid (C22) and lignoceric acid (C24).

[0047] A comparison of stearic and isostearic acids shows that branching leads to a high melting point and results in low viscosity at room temperature for isostearic acid, compared to a solid material for stearic acid. This lower viscosity can be useful in handling raw materials and also to allow esters made with this acid to retain their liquid properties. Branched-chain fatty acids often contain a single methyl group along the linear carbon chain and are produced in nature by microbial action. Isotearic acid is available as a reaction byproduct in the creation of the dimeric acid described above.

[0048] Another way to obtain a liquid product is to use linear and branched unsaturated fatty acids. 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), α-linolenic acid (C18:3), α-linolenic acid (C18:3), stearidonic acid (C18:4), paullinic acid (C20:1), gondolic acid (C20:1), dihomo-α-linolenic acid (C20:3), mead acid (C20:3), arachidonic acid (C20:4), eicosapentaenoic acid (C20:5), erucic acid (C22:1), acid docosatetraenoic (C22:4), cervonic acid (C22:6) and nervonic acid (C24:1). As is well known to those skilled in the art, the designation means that the length of the carbon chain is X carbon atoms; and there are Y double bonds in the chain.

[0049] In one embodiment, isostearic acid will be preferred.

[0050] In a particularly preferred embodiment, the polyester of the invention is a substantially or totally non-sequential reaction product of the following components: (i) at least one polyglycerol-3 in mixture form comprising 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 polyglycerol-3 in mixture form; (ii) at least one hydrogenated dimeric acid containing at least 60% by weight of hydrogenated C36 diacid and 5 to 25% by weight of hydrogenated C54 triacid, in each case relative to the total weight of hydrogenated acid; and iii) isostearic acid.

[0051] In one embodiment, the polyester is prepared by a one-step process which involves introducing all the reactants into a reaction vessel and then inducing a fully statistical addition of the dimer acid and isostearic acid to polyglycerol-3.

[0052] In one embodiment, it is preferable to have a total degree of esterification of the available polyglycerol hydroxyl fragments (total esterification) of 24% to 74% and a degree of esterification of the available polyglycerol hydroxyl fragments by a dimer acid alone (esterification with a dimer acid) of 20% to 40%. Most importantly, the degree of esterification by the end-cap units (esterification with a monoacid) is also defined in this description, and it is important to maintain the esterification with a monoacid of 4% to 40%.

[0053] 11 It is preferable to have a total esterification of 28% to 57% with an esterification with a dimeric acid of 20% to 30% and an esterification with a monoacid between 8% and 27%.

[0054] It is even more preferable to have a total esterification of 33% to 48% with an esterification with a dimeric acid of 20% to 28% and an esterification with a monoacid between 13% and 20%.

[0055] It is even more preferable to have a total esterification of 24% to 74% with an esterification with a hydrogenated dimeric acid of 20% to 40% and an esterification with a monoacid between 4% and 40%.

[0056] It is even more preferable to have a total esterification of 28% to 57% with an esterification with a hydrogenated dimeric acid of 20% to 30% and an esterification with a monoacid between 8% and 27%.

[0057] It is also even more preferable to have a total esterification of about 40% with an esterification with a hydrogenated dimeric acid of about 20% and an esterification with a monoacid of about 20%.

[0058] It is also even more preferable to have also most preferred a total esterification of about 40% with an esterification with a hydrogenated dimeric acid of about 27% and an esterification with a monoacid of about 13%.

[0059] In one embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.5 to 1 mole of dimer acid and 0.2 to 1.7 mole of fatty acid.

[0060] In another embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.5 to 0.75 mole of dimer acid and 0.4 to 1.35 mole of isostearic acid.

[0061] In another embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.5 to 0.7 mole of dimer acid and 0.65 to 1 mole of isostearic acid.

[0062] In another embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.5 to 1 mole of hydrogenated dimer acid and 0.2 to 1.7 mole of isostearic acid.

[0063] In another embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.5 to 0.75 mole of hydrogenated dimer acid and 0.4 to 1.35 mole of isostearic acid.

[0064] In another embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.5 to 0.7 mole of hydrogenated dimer acid and 0.65 to 1 mole of isostearic acid.

[0065] In another embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.5 to 1 mole of hydrogenated dimer acid and 0.2 to 1.7 mole of isostearic acid.

[0066] In another embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.5 to 0.75 mole of hydrogenated dimer acid and 0.4 to 1.35 mole of isostearic acid.

[0067] In another embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.5 to 0.7 mole of hydrogenated dimer acid and 0.65 to 1 mole of isostearic acid.

[0068] In another embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.67 mole of hydrogenated C36 dimer acid and 0.67 mole of isostearic acid.

[0069] In a particularly preferred embodiment, the components to be reacted are in a molar ratio of 1 mole of polyglycerol-3, 0.5 mole of hydrogenated C36 dimer acid and 1 mole of isostearic acid.

[0070] By adjusting the molar ratio of fatty acid termination and balancing the amount of polyglycerol-3 and dimer acid, it is also possible to control the degree of dimer-polyglycerol extension and termination so that crosslinking, for example, via the acid trimer, leads to much higher viscosities.

[0071] The target viscosity of the pure polymer must be > 50,000 mPa.s and less than 5,000,000 mPa.s at 25 °C.

[0072] In a preferred embodiment, the target viscosity is > 75,000 mPa.s and < 2,500,000 mPa.s at 25°C.

[0073] In another preferred embodiment, the target viscosity is > 100,000 mPa.s and < 2,000,000 mPa.s at 25°C.

[0074] In a preferred embodiment of all, the target viscosity is > 1,000,000 mPa.s and < 2,000,000 mPa.s at 25°C.

[0075] Viscosity is measured using an MCR3O2® rheometer from Anton Paar Inc. Twin flat plates, either rough or smooth, 50 mm in diameter, were used, coated with a polymer sample, fitted with a gap of 0.5 to 1 mm, and temperature and shear rate scans were performed. The polyesters of the invention exhibit Newtonian behavior and therefore have a constant viscosity over a wide range of shear rates. Furthermore, the polymers described have demonstrated a viscosity that decreases 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.

[0076] The polyesters of the invention are characterized by average molecular masses by weight > 2500 Da and < 1,000,000 Da measured by GPC using linear polystyrene standards.

[0077] The GPC column used for these tests consisted of: Phenolgel, 300 x 4.6 mm; a continuous phase of Tetrahydrofuran (THF) 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 for monodisperse application. The narrow-range polystyrene GPC calibration standards were prepared in mobile phase and had maximum molecular weights of 1,290,000 Da; 560,000 Da; 65,500 Da; 28,500 Da; 10,100 Da; 1,680 Da; 580 Da and 208 Da. From standard methodologies, the mass The average molecular weight and number is automatically calculated by standard GPC software.

[0078] In a preferred embodiment, the described polyesters have a weight-average molecular weight > 4,000 Da and < 250,000 Da measured by GPC using linear polystyrene standards. In a most preferred embodiment, the described polymers have a weight-average molecular weight > 5,000 Da and < 150,000 Da measured by GPC using linear polystyrene standards.

[0079] In yet another embodiment, the polyester of the invention has a combination of average molecular mass by weight > 5000 Da and < 150,000 Da measured by GPC using linear polystyrene standards and viscosity at 25°C > 100,000 mPa.s and < 2,000,000 mPa.s.

[0080] In a preferred embodiment, the polyester of the invention is a substantially or completely non-sequential reaction product 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 mixture form; (ii) at least one hydrogenated dimeric acid containing at least 60% by weight of hydrogenated C36 diacid and 5 to 25% by weight of hydrogenated C54 triacid, in each case relative to the total weight of hydrogenated acid; and (iii) isostearic acid; wherein the polymer exhibits a weight-average molecular weight combination > 5,000 Da and < 15,000 Da measured with GPC using linear polystyrene standards and a viscosity of the pure polymer > 100,000 mPa.s and < 2,000,000 mPa.s at 25°C; and wherein the copolymer is also characterized by a total esterification of about 40%, an esterification with a hydrogenated dimeric acid of about 27% and an esterification with a monoacid of about 13%.

[0081] In practice, since the raw ingredients contain a range of polyglycerol units and a range of dimer and trimer acid contents, the above numbers can be adjusted using the actual (not theoretical) hydroxyl and carboxylic acid fractions as determined by methods such as mass spectrometry, NMR, and liquid chromatography. The esterification ranges above are based on the ideal structure of polyglycerol-3 and the C36 dimer acid. The actual ranges may therefore differ slightly from the values ​​given above and can be calculated based on these analytical values.

[0082] It is more practical to define the extent of polymerization by the final acid value. The initial acid values, in light of the distribution of the polyglycerol fractions, Monoacids and polyacids present can be reliably calculated using the actual acid value determined by the raw ingredient used.

[0083] For example, the initial total acid number ("AV," which is commonly defined as mg of KOH / g of total reagent) is 135 AV. This includes 68 AV for the dimer acid and 67 AV for the isostearic acid for a preferred embodiment containing 1 mole of polyglycerol-3, 0.5 mole of hydrogenated C36 dimer acid, and 1 mole of isostearic acid. All preferred ratio embodiments described above have a corresponding initial AV that can be calculated. When, during the polymerization reaction, the AV units are reduced, this ratio gives the percentage conversion of the reaction from the total initial reactive acid fractions to the final residual acid fractions.

[0084] Thus, the completion rate of the reaction is defined by (1 - final AV) / initial AV.

[0085] In one embodiment, the polyesters of the invention have final acid indices of 0.1 to < 25 mg KOH / g of polymer.

[0086] In a preferred embodiment, the polyesters of the invention have final acid indices of 0.1 to < 10 mg KOH / g of polymer.

[0087] In a preferred embodiment, the polyesters of the invention have final acid indices of 0.1 to < 5 mg of KOH / g of polymer.

[0088] The completion rate of the reaction being defined by the equation 1- final AV / initial AV, the completion rate of the reaction of such mixtures in final polymer is > 80%.

[0089] In a preferred embodiment, the completion rate of the reaction of such mixtures into the final polymer is > 90%.

[0102] The composition according to the invention comprises a lipophilic silicone polymer. A "lipophilic polymer" is understood to mean a polymer that is soluble or dispersible in oils.

[0103] The lipophilic silicone polymers used according to the invention can be selected from silicone resins, silicone polyamides, vinyl polymers comprising a carbosiloxane dendrimer-derived motif, silicone acrylate copolymers, and mixtures thereof. Silicone resins

[0104] According to one embodiment, a composition according to the invention may include, as a lipophilic silicone polymer, at least one silicone resin.

[0105] More generally, the term "resin" refers to a compound with a three-dimensional structure. "Silicone resins" are also called "silicon resins" or "siloxane resins." Thus, for the purposes of the present invention, a polydimethylsiloxane is not a silicone resin.

[0106] The nomenclature of silicone resins (also called siloxane resins or silicone resins) is known as "MDTQ", the resin being described according to the different siloxane monomeric units it comprises, each of the letters "MDTQ" characterizing a type of unit.

[0107] The letter “M” represents the Monofunctional unit of formula RlR2R3SiOi / 2, the silicon atom being bonded to a single oxygen atom in the polymer comprising this unit.

[0108] The letter “D” signifies a Difunctional unit R1 R2SiO2 / 2 in which the silicon atom is bonded to two oxygen atoms

[0109] The letter “T” represents a Trifunctional unit of formula RlSiO3 / 2.

[0110] Such resins are described, for example, in "Encyclopedia of Polymer Science" and Engineering, vol. 15, John and Wiley and Sons, New York, (1989), p. 265-270, and US 2,676,182, US 3,627,851, US 3,772,247, US 5,248,739 or even US 5,082,706, US 5,319,040, US 5,302, 685 and US 4,935,484.

[0111] In the motifs M, D, T defined above, R, namely RI and R2, represents a hydrocarbon radical (in particular alkyl) having from 1 to 10 carbon atoms, a phenyl group, a phenylalkyl group or even a hydroxyl group.

[0112] Finally, the letter “Q” signifies a tetrafunctional SiO4 / 2 unit in which the silicon atom is bonded to four oxygen atoms which are themselves bonded to the rest of the polymer.

[0113] Various silicone resins of different properties can be obtained from these different units, the properties of these polymers varying according to the type of monomers (or units), the nature and number of the radical R, the length of the polymer chain, the degree of branching and the size of the dangling chains.

[0114] As examples of silicone resins that can be used in the compositions according to the invention, silicone resins of type MQ, type T or type MQT can be used.

[0119] T Resins:

[0120] As an example of T-type silicone resins, we may cite polysilsesquioxanes of formula (RSiO3 / 2)x (T units) in which x is greater than 100 and such that the R group is an alkyl group having from 1 to 10 carbon atoms, said polysilsesquioxanes being able to further comprise Si-OH terminal groups.

[0121] Preferably, polymethylsilsesquioxane resins in which R represents a methyl group may be used, such as, for example, those commercially available:

[0122] - by the company Wacker under the reference Resin MK such as the Belsil PMS MK: polymer comprising repeating CH3SiO3 / 2 units (T units), which may also comprise up to 1% by weight of (CH3)2SiO2 / 2 units (D units) and having an average molecular weight of about 10000 g / mol, or

[0487] The temperature of the bulk was checked: If the temperature increases, the beaker was placed in a cold water bath.

[0488] Finally, ethanol was added at room temperature (below 30°C) under rotor-stator stirring at 1000 rpm. The mixture was left under stirring for another 5 minutes and then packaged.

[0489] In vitro test for evaluating adhesion and non-transfer

[0490] Each composition was applied to an Erichsen contrast card, using a spreader, in a deposit with a thickness of 50 µm, over a width of at least 6 cm, and left to dry on a hot plate for 40 minutes at 32°C.

[0491] Three strips of WyPall© 05701 7471 L40 (Kimberley Clark) 2 cm wide and 3 cm long were deposited on the deposit without overlapping:

[0492] - the first strip is dry,

[0493] - the second strip is soaked in distilled water (0.1ml)

[0494] - the third is soaked in olive oil (0.1ml).

[0495] The film puller, weighted with a 2 kg weight, was placed on top of all the strips, and the assembly was moved along the film. Finally, the state of the deposit was observed after the strips had passed over it.

[0496] The following notation was made on the degradation of the deposit:

[0497] [Tables2] Note: Condition of the deposit. Surface of the fabric in contact with the deposit: 5. Total or partial removal of the deposit on the rubbed area; the surface of the support appears in places. Very intense staining, very significant to total color transfer. 4. Partial removal resulting in a significantly and visibly less intense staining of the deposit. Intense staining, significant color transfer. 3. Perceptible decrease in the intensity of the deposit's color, but the support is not visible. Medium staining, medium color transfer. 2. No substantial change in the deposit's color. Slight staining, little color transfer. 1. No change in the deposit's color. No staining or barely visible staining, little to no color transfer.

[0498] The following results were obtained:

[0499] [Tables3] Observations Example 1 (Invention) Example 2 (Comparative) Example 3 (Comparative) Deposition of the deposit Dry = 1 Dry = 1 Dry = 1 Water = 1 Water = 1 Water = 1 Oil = 1 Oil = 1 Oil = 1 Fabric staining Dry = 2 Dry = 2 Dry = 3 Water = 1 Water = 1 Water = 1 Oil = 1 Oil = 1 Oil = 2

[0500] These results show that the composition of Example 1 containing polyester and silicone resin provides less transfer than that obtained with the composition of Example 3 containing polyester, both dry and in the presence of oil. The transfer is similar to that of the composition of Example 2 containing silicone resin, without polyester.

[0501] The composition of example 1 therefore makes it possible to reduce the silicone resin content without losing in content and transfer performance.

[0502] Comparative examples 4 and 5:

[0503] A composition according to the invention (example 4) and a comparative composition outside the invention (example 5) were prepared, similar to that of example 1 by modifying the weight ratio of polyester / lipophilic silicone polymer.

[0505]

[0506] following: [Tables 5] Observations Example 1 (Invention) Example 4 (Invention) Example 5 (Comparative) Deposition of the deposit Dry = 1 Dry = 1 Dry = 1 Water = 1 Water = 1 Water = 1 Oil = 1 Oil = 1 Oil = 1 Fabric dyeing: Dry = 2 Dry = 2 Dry = 3 Water = 1 Water = 1 Water = 1 Oil = 1 Oil = 1 Oil = 2

[0507] These results show that the compositions of examples 1 and 4 confer a lower dry and oil transfer than that of example 5.

[0508] Thus the weight ratio between the polyester and the lipophilic silicone polymer must be less than 7 to obtain the good non-transfer properties in dry and oil conditions. Example 6#:

[0509] A composition according to the following invention (example 6) has been prepared:
