Description

Title of the invention: COSMETIC COMPOSITION COMPRISING A PARTICULAR POLYESTER, AT LEAST ONE VOLATILE SOLVENT AND A DIATOMACEOUS EARTH TYPE FILLER AND METHOD FOR IMPLEMENTING IT

[0001] The present invention relates to a cosmetic composition, preferably for makeup in particular for the skin and / or lips, comprising at least one polyester obtained by reaction of a polyglycerol-3, a dimeric acid and a monoacid in C8-C30, at least one volatile solvent, optionally at least one non-volatile hydrocarbon oil and at least one filler of the diatomaceous earth type, as well as a process implementing it.

[0002] Many cosmetic compositions, in particular makeup, containing among other things coloring materials, such as foundations, correctors, lipsticks, lip glosses, have been developed to improve hold and non-transfer properties.

[0003] Improving the durability of compositions is achieved through compositions that form a film after application. Such compositions generally contain volatile solvents that evaporate upon contact with the skin or lips, leaving behind a layer comprising waxes and / or film-forming polymers, pigments, and fillers. Film-forming polymers are synthetic polymers, often silicone or acrylic. Examples include silicone resins, such as trimethylsiloxysilicate (INCI name) or polypropylsilsesquioxane (INCI name), or those containing silicone polymers such as silicone acrylate dendrimer copolymers (acrylates / polytrimethylsiloxymethacrylate copolymer (INCI name)). Acrylic polymers such as Acrylic Acid / Isobutyl Acrylate / Isosomal Acrylate Copolymer are also used.However, these compositions are often considered less comfortable, or even uncomfortable, from a sensory point of view for consumers. As for the fillers, they are chosen primarily for their ability to absorb sebum, sweat, and / or oils from the composition, and are often polymeric fillers. Yet such fillers can be considered "microplastics," which we are also trying to avoid.

[0004] Indeed, in recent years, consumers have become more demanding regarding the composition of their cosmetic products and are particularly seeking to minimize the content of silicone compounds, or even to do without them altogether. In return, they are looking to use products with a higher content of natural ingredients or of natural origin, in ingredients whose environmental impact is minimized and / or ingredients that are compatible with many packaging types.

[0005] Thus, the formulation of environmentally friendly cosmetic products, that is, products whose design and development take environmental issues into account, is becoming a major concern in order to help meet global challenges. It is therefore essential to offer more sustainable compositions and / or preparation processes and / or ingredients that can address these environmental challenges.

[0006] In this context, it is important to develop new cosmetic compositions with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or with a good naturalness index and / or of natural origin and more particularly of plant origin, while reducing the use of petrochemical compounds.

[0007] The difficulty remains, however, to reconcile these latest trends with the fact that consumers do not want to give up the very high performance to which they have become accustomed with the products they already use, which include, in particular, silicone film-forming polymers.

[0008] We are therefore still looking for cosmetic compositions, particularly makeup, that are high-performing, comfortable, and also have good staying power, without the need to use the film-forming polymers that are classically used, in particular silicone polymers, and that are more environmentally friendly, by using, for example, more natural or naturally derived compounds.

[0009] These problems and others are solved by the present invention, which relates to a cosmetic composition, preferably a makeup composition of human keratinous materials, in particular skin and / or lips, comprising, in a physiologically acceptable medium: - at least one 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) reacting 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 mono-fatty acid, - at least one volatile solvent, - possibly at least one non-volatile hydrocarbon oil, - at least one diatomaceous earth type filler.

[0010] The present invention also relates to a method for processing human keratinous materials, preferably makeup, in which the aforementioned cosmetic composition is applied to human keratinous materials, in particular the skin and / or lips.

[0011] The composition according to the invention is stable over time and, when applied to the lips, has the advantage of being easy to apply, without clumping or blotting. The resulting deposit is also precise, homogeneous, non-stringy, and slightly or not at all sticky. The deposit does not migrate into wrinkles and fine lines, particularly around the lips.

[0012] The resulting deposit has good adhesion. It is also comfortable, without leaving a feeling of dryness or tightness.

[0013] When applied to the skin, for example in the form of an emulsion, the composition according to the invention is easy to apply, lightweight, non-sticky, and comfortable. It allows for a very homogeneous distribution of pigments and pearlescent particles on the skin, without a mask-like effect.

[0014] The deposit obtained by applying the composition also exhibits good resistance over time, and this without using silicone film-forming polymers.

[0015] The composition according to the invention is advantageously in the form of a liquid composition.

[0016] By "liquid composition" is meant any composition which has one or more of the following characteristics:

[0017] i) flows by its own weight at ambient temperature (20°C) and atmospheric pressure (1.013 .105 Pa);

[0018] ii) is not solid at room temperature and atmospheric pressure and whose viscosity or consistency can be measured, characterized by its hardness;

[0019] iii) does not have any particular shape such as that which can be obtained by hot casting in a mold or container of a given shape.

[0020] Such compositions may therefore be found in particular in fluid, creamy, pasty or gel form. Protocol for measuring viscosity

[0021] Viscosity measurement is generally carried out at 25°C, using a RHEOMAT RM 180 viscometer equipped with a wheel no. 2, no. 3 or no. 4, the measurement being carried out after 10 minutes of rotation of the wheel within the composition (time at the end of which a stabilization of the viscosity and the rotation speed of the wheel is observed), at a speed of 200 revolutions / min (rpm).

[0022] According to one embodiment, the composition according to the invention may have a viscosity at 25°C 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 can be between 0.2 and 10 Pa.s.

[0023] In particular, the viscosity at 25°C of a composition according to the invention can be between 0.1 Pa.s (mobile 2) and 25 Pa.s (mobile 4), preferably between 0.2 Pa.s (mobile 2) and 20 Pa.s (mobile 4), and better between 0.2 Pa.s (mobile 2) and 10 Pa.s (mobile 4).

[0024] In the context of the present invention, "human keratinous material" means, in particular, skin, lips, eye contour, eyelids, eyelashes and eyebrows.

[0025] POLYGLYCEROL-3 POLYESTER / DIMER ACID / FATTY MONO ACID

[0026] The composition according to the invention comprises at least one 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.

[0027] 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'.

[0028] 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.

[0029] 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.

[0030] According to a preferred embodiment, the polyester is a substantially or totally non-sequential reaction product.

[0031] By "substantially non-sequential reaction product", we mean the product obtained by a substantially non-sequential reaction of the reactive components (i)-(iii).

[0032] 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 container before starting the reaction.

[0033] 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.

[0034] 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. Polyglycerol-3

[0035] Triglycerol has the formula H-[-OGly]3-OH in which Gly designates a remainder of glycerol after the removal of two hydroxyl groups.

[0036] 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 oligocondensation product of glycerol. They preferably conform to the 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.

[0037] 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.

[0038] 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.

[0039] Particularly suitable examples of polyglycerol-3 include a mixture of polyglycerols having the following distribution in which all the Weight percentages are based relative 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.

[0040] In one embodiment, a polyglycerol-3 in the form of a mixture 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.

[0041] 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.

[0042] 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% in weight of tetraglycerol; in which all percentages by weight relative to the total weight of polyglycerol-3 in mixture form.

[0043] 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.

[0044] 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

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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).

[0050] 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.

[0051] 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 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.

[0052] In one embodiment, the copolymer of the present invention is prepared from at least one hydrogenated dimeric acid.

[0053] 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.

[0054] 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.

[0055] 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

[0056] 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.

[0057] 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).

[0058] 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.

[0059] Another way to obtain a liquid product is to use linear and branched unsaturated fatty acids. These unsaturated acids may include palmitoleic acid (C16:l), vaccenic acid (C18:l), oleic acid (C18:l), elaidic acid (C18:l), 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:l), gondolic acid (C20:l), dihomo-α-linolenic acid (C20:3), mead acid (C20:3), arachidonic acid (C20:4), eicosapentaenoic acid (C20:5), erucic acid (C22:l), docosatetraenoic acid (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 carbon chain is X carbon atoms long; and there are Y double bonds in the chain.

[0060] In one embodiment, isostearic acid will be preferred.

[0061] 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.

[0062] 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.

[0063] 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%.

[0064] 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%.

[0065] 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%.

[0066] 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%.

[0067] 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%.

[0068] 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%.

[0069] 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%.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] The target viscosity of the pure polymer must be > 50,000 mPa.s and less than 5,000,000 mPa.s at 25 °C.

[0083] In a preferred embodiment, the target viscosity is > 75,000 mPa.s and < 2,500,000 mPa.s at 25°C.

[0084] In another preferred embodiment, the target viscosity is > 100,000 mPa.s and < 2,000,000 mPa.s at 25°C.

[0085] In a preferred embodiment of all, the target viscosity is > 1,000,000 mPa.s and < 2,000,000 mPa.s at 25°C.

[0086] 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 The polymers 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 decrease in viscosity with temperature. Thus, viscosity measurements are reported at a precisely controlled temperature and generally in the form of a shear rate of 1. Values ​​are reported in mPa·s.

[0087] 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.

[0088] 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. Using standard methodologies, the average molecular mass by weight and number is automatically calculated by standard GPC software.

[0089] 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 preferred embodiment of all, the described polymers have a weight-average molecular weight > 5,000 Da and < 150,000 Da measured by GPC using linear polystyrene standards.

[0090] 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.

[0091] 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 wt% diglycerol, at least 45 wt% triglycerol and at least 10 wt% 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 wt% hydrogenated C36 diacid and 5 to 25 wt% hydrogenated C54 triacid, in each case relative to the total weight of hydrogenated acid; and (iii) isostearic acid; in which the polymer exhibits a combination of weight average molecular weight > 5,000 Da and < 15,000 Da measured with GPC using linear polystyrene standards and pure polymer viscosity > 100,000 mPa.s and < 2,000,000 mPa.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%.

[0092] 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.

[0093] 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, monoacid, and polyacid fractions present, can be reliably calculated using the actual acid value determined by the crude ingredient used.

[0094] 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.

[0095] Thus, the completion rate of the reaction is defined by 1 - final AV / initial AV.

[0096] In one embodiment, the polyesters of the invention have acid indices final concentrations of 0.1 to < 25 mg of KOH / g of polymer.

[0097] In a preferred embodiment, the polyesters of the invention have final acid indices of 0.1 to < 10 mg KOH / g of polymer.

[0098] In a preferred embodiment, the polyesters of the invention have final acid indices of 0.1 to < 5 mg KOH / g of polymer.

[0099] Since the completion rate of the reaction is defined by equation 1- final AV / initial AV, the completion rate of the reaction of such mixtures in the final polymer is > 80%.

[0100] In a preferred embodiment, the completion rate of the reaction of such mixtures into the final polymer is > 90%.

[0101] In a preferred embodiment, the completion rate of the reaction of such mixtures into the final polymer is > 95%.

[0102] In a preferred embodiment, the polyester of the invention is a reaction product of a polyglycerol-3, a C36 hydrogenated dimeric acid and isostearic acid in a molar ratio of 1 / 0.5 / 1 as described in Example 10 (copolymer) of US document 2021 / 0259945.

[0107] Said polyester oil solution preferably contains polyester at a concentration of 10 to 99% by weight, more preferably 30 to 90% by weight, more particularly 50 to 80% by weight relative to the total weight of the mixture.

[0109] According to a particularly preferred embodiment of the invention, the composition comprises an oily solution comprising: a) a polyester obtained by reaction (i) of a polyglycerol-3, and (ii) of a C36 hydrogenated acid dimer; and (iii) isostearic acid; components (i), (ii) and (iii) reacted being in a molar ratio of 1 mole of polyglycerol, 0.5 to 1 mole of dimer acid and 0.1 to less than 2.0 moles of fatty acids; and b) a caprylic / capric acid triglyceride; said mixture having the INCI name: Diisostearoyl Polyglyceryl-3 Dimer Dilinoleate (and) Caprylic / Capric Triglyceride.

[0162] By "charge" is to be understood a colorless or white, solid particle of any shape, which is insoluble and dispersed in the medium of the composition

[0163] Diatomaceous earth is composed of microporous siliceous fossilized skeletal remains from aquatic algae called diatoms.

[0164] More specifically, the average particle size (d

[50] by volume) varies from 1 to 20 pm. Particle sizes are measured using a commercial MasterSizer 2000® particle size analyzer from Malvem. The data are processed based on Mie scattering theory. This theory, accurate for isotropic particles, allows us to determine an "effective" particle diameter in the case of non-spherical particles. This theory is notably described in Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957. Diatomaceous earth particles are porous.

[0165] For the purposes of this invention, "porous particles" means particles having a structure comprising pores or interstices.

[0166] Among the diatomaceous earths that can be used in the context of the present invention, we can mention the products of the ImerCare D range from the company Imerys, for example ImerCare 03D, ImerCare 06D, ImerCare 400D, ImerCare Vistalskin.

[0179] If the composition is in the form of an emulsion, in particular an inverse emulsion, it comprises one or more surfactants, preferably non-ionic, with an HLB of less than or equal to 8.

[0180] For the purposes of the present invention, "surfactant" means an amphiphilic surfactant compound, that is to say, having two parts of different polarity. Generally, one part is lipophilic (soluble or dispersible in an oil phase), and the other is hydrophilic (soluble or dispersible in water). Surfactants are characterized by their HLB (Hydrophilic-Lipophilic Balance), where HLB is the ratio of the hydrophilic to the lipophilic part of the molecule. The term HLB is well known to those skilled in the art and is described, for example, in "The HLB System: A Time-Saving Guide to Emulsifier Selection" (published by ICI Americas Inc., 1984). For surfactants, the HLB typically ranges from 3 to 8 for the preparation of oil-in-water emulsions. The HLB of the surfactant(s) used according to the invention can be determined by the Griffin method or the Davies method.

[0181] Preferably, non-siliconized non-ionic surfactants may be mentioned, in particular alkyl esters or ethers of sorbitan, glycerol, polyol, or sugars. Surfactants whose chemical structure results from the reaction of at least one polyhydroxystearic acid and / or at least one polyricinoleic acid with a polyol containing at least two alcohol functional groups are particularly suitable.

[0227] The additional charges may be inorganic or organic.

[0228] Preferably, they may be chosen from natural or naturally sourced fillers.

[0229] By “natural charge” or “natural compound” is meant a compound which is obtained directly from the earth or soil, or from plants or animals, via, where appropriate, one or more physical processes, such as grinding, refining, distillation, purification or filtration.

[0230] The term “naturally sourced filler” or “naturally sourced compound” means a natural compound that has undergone one or more additional chemical or industrial treatments, resulting in modifications that do not affect the essential qualities of that compound, and / or a compound consisting mainly of natural constituents that may or may not have undergone transformations. As a non-limiting example of ancillary chemical or industrial treatments that result in modifications that do not affect the essential qualities of a natural compound, one may mention those authorized by control bodies such as Ecocert (Reference Guide for Organic and Ecological Cosmetic Products, January 2003) or defined in recognized manuals in the field, such as “Cosmetics and Tissue Magazine”, 2005, vol. 120, 9: 10.

[0236] The composition according to the invention may include at least one hydrocarbon wax, polar or non-polar.

[0237] For the purposes of this invention, "wax" means a lipophilic compound, solid at room temperature, with a reversible solid / liquid change of state, having a melting point greater than or equal to 30°C and up to 120°C.

[0238] For the purposes of the invention, the melting temperature corresponds to the temperature of the most endothermic peak observed in thermal analysis (DSC) as described in ISO 11357-3; 1999. The melting point of the wax can be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name "DSC Q2000" by TA Instruments with the "TA Universal Analysis" software.

[0239] The measurement protocol is as follows: A 5 mg sample of wax is placed in a crucible and subjected to a first temperature increase from -20°C to 120°C, at a heating rate of 10°C / minute, then is cooled from 120°C to -20°C at a cooling rate of 10°C / minute and finally subjected to a second temperature increase 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 fat is measured, corresponding to the temperature of the most endothermic peak of the observed melting curve, representing the variation of the difference in absorbed power as a function of temperature. The enthalpy of fusion of the wax (AHf) can also be measured, corresponding to the integral of the entire melting curve obtained. This enthalpy of fusion of the wax is the amount of energy required to change the compound from a solid to a liquid state. It is expressed in J / g.

[0240] Waxes can be of vegetable, mineral, animal and / or synthetic origin.

[0241] In particular, waxes have a preferred melting point greater than or equal to 35°C and preferably greater than or equal to 40°C. Non-polar waxes

[0242] By "nonpolar hydrocarbon wax", in the context of the present invention, means a wax consisting solely of carbon and hydrogen atoms and free from heteroatoms, such as for example N, O, Si, P....

[0243] Examples of non-polar waxes suitable for the invention include hydrocarbon waxes such as microcrystalline waxes, paraffin waxes, ozokerite, polymethylene waxes, polyethylene waxes, and micro-waxes, particularly polyethylene waxes. Polar waxes

[0244] Polar waxes can in particular be hydrocarbon or silicone-based.

[0245] For the purposes of this invention, "polar hydrocarbon wax" means a wax whose chemical structure is essentially formed, or even composed, of carbon and hydrogen atoms, and comprising at least one heteroatom, more particularly selected from oxygen, possibly nitrogen, or mixtures thereof. It may thus contain alcohol, ester, ether, carboxylic acid, amine and / or amide groups.

[0246] By "siliconized wax" is meant an oil comprising at least one silicon atom, and in particular comprising Si-O groups.

[0247] According to a first preferred embodiment, polar wax is a hydrocarbon wax.

[0248] As a hydrocarbon polar wax, a wax chosen from ester waxes and alcohol waxes is preferred.

[0249] According to the invention, "ester wax" means a wax comprising at least one ester function. Ester waxes may also be hydroxylated.

[0250] By "alcohol wax", according to the invention, a wax comprising at least one alcohol function, that is to say comprising at least one free hydroxyl (OH) group.

In particular, an alkyl (hydroxystearyloxy)stearate in the C2O-C4O group (the alkyl group comprising 20 to 40 carbon atoms) can be used as an ester wax, alone or in a mixture, or an alkyl stearate in the C2O-C4O group. Such waxes are notably sold under the names "Kester Wax K 82 P®", "Hydroxypolyester K 82 P®", "Kester Wax K 80 P®", or "Kester Wax K82H" by the Koster Keunen company. Stearyl heptanoate and stearyl caprylate and their mixtures can also be used. ii) di-(trimethyloi-1,1,1 propane tetrastearate), (iii) Diester waxes of a dicarboxylic acid of general formula R3-(-OCO-R4-COO-R5), wherein R3 and R5 are identical or different, preferably identical, and represent a C4-C30 alkyl group, and R4 represents a linear or branched C4-C30 aliphatic group, which may or may not contain one or more unsaturates. Preferably, the C4-C30 aliphatic group is linear and unsaturated. (iv) We can also mention waxes obtained by catalytic hydrogenation of animal or vegetable oils having, in particular, linear or branched fatty chains in the C8-C32 range, for example, hydrogenated jojoba oil, hydrogenated sunflower oil, hydrogenated castor oil, hydrogenated coconut oil, as well as waxes obtained by hydrogenation of esterified castor oil with cetyl alcohol, such as those sold in the Phytowax Castor range, for example Phytowax Castor 22L73®, or waxes obtained by hydrogenation of esterified olive oil with stearyl alcohol, such as those in the Phytowax Olive range, for example Phytowax Olive 18L57, marketed by the company Sophim. Such waxes are described in particular in application FR2792190. (v) Waxes corresponding to partial or total esters, preferably total, of a saturated C16-C30 carboxylic acid, optionally hydroxylated, with glycerol. By total esters, it is understood that all the hydroxyl groups of glycerol are esterified. Examples include trihydroxystearine (or glyceryl trihydroxystearate), tristearine (or glyceryl tristearate), and tribehenin (or glyceryl tribehenate), alone or in mixtures. Suitable compounds include triesters of glycerol and 12-hydroxystearic acid, or of hydrogenated castor oil, such as Thixcin R and Thixcin E, marketed by Elementis Specialties. vi) We can also mention waxes of animal or vegetable origin, such as beeswax, synthetic beeswax, camauba wax, candelilla wax, rice bran wax, Ouricury wax, Alfa wax, cork fiber wax, wax of sugar cane, Japanese wax, sumac wax, montan wax, orange wax, laurel wax, sunflower wax, especially refined. vii) We can also mention hydrocarbon waxes, polyoxyalkylated or polyglycerolated, natural or synthetic, of animal or vegetable origin; the number of oxyalkylated units (in C2-C4) can vary from 2 to 100, the number of glycerol units can vary from 1 to 20. By way of example, we can mention polyoxyethylenated beeswax, such as PEG-6 beeswax, PEG-8 beeswax; polyoxyethylenated carnauba wax, such as PEG-12 carnauba; lanolin waxes, hydrogenated or not, polyoxyethened or polyoxypropylenated, such as PEG-30 lanolin, PEG-75 lanolin; PPG-5 lanolin wax glyceride; polyglycerolized beeswaxes, including polyglyceryl-3 Beewax, the Acacia Decurrens / Jojoba / Sunflower Seed Wax / Polyglyceryl-3 Esters blend, polyglycerolized vegetable waxes such as mimosa, jojoba, sunflower waxes, and their blends (Acacia Decurrens / Jojoba / Sunflower Seed Wax Polyglyceryl-3 Esters).

[0252] According to another embodiment, the polar wax can be an alcohol wax. Examples of alcohol waxes include mixtures of linear, saturated, C3o-C5o alcohols such as, for example, Performacol 550 Alcohol wax from New Phase Technologie, stearic alcohol, cetyl alcohol, or mixtures thereof.

[0253] Preferably, if the composition includes it, the wax is chosen from among hydrocarbon waxes. More particularly, it is chosen from among non-polar waxes; polar hydrocarbon waxes such as waxes of animal or vegetable origin, waxes of animal or vegetable origin obtained by catalytic hydrogenation of animal or vegetable oils; alcohol waxes; as well as mixtures thereof; and preferably from among non-polar hydrocarbon waxes, alone or in mixtures.

[0254] The wax content, if included in the composition, varies advantageously from 1 to 20% by weight, in particular from 5 to 15% by weight, relative to the total weight of the composition. Pasty compounds

[0255] The composition according to the invention may also include at least one paste-like compound at room temperature and atmospheric pressure.

[0256] For the purposes of this invention, "pasty" means a lipophilic compound with reversible solid / liquid phase change, exhibiting in particular in the solid state an anisotropic crystalline organization, and comprising at room temperature a liquid fraction and a solid fraction.

[0257] In other words, the initial melting temperature of the paste-like compound may be lower than room temperature. The liquid fraction of the paste-like compound measured at room temperature may represent 9 to 97% by weight of the compound pasty. This liquid fraction at room temperature preferably represents between 15 and 85%, and even more preferably between 40 and 85% by weight.

[0258] The melting point of the pasty fat is determined according to the same principle as that detailed previously for waxes. However, in the case of a pasty compound, the measurement protocol is as follows: A 5 mg sample of pasty fat placed in a crucible is subjected to a first temperature increase from -20°C to 100°C, at a heating rate of 10°C / minute, then is cooled from 100°C to -20°C at a cooling rate of 10°C / minute and finally subjected to a second temperature increase from -20°C to 100°C at a heating rate of 5°C / minute. The melting point of the pasty fat is the temperature value corresponding to the peak of the curve representing the variation of the difference in absorbed power as a function of temperature. It should be noted that the liquid fraction by weight of the pasty fat at room temperature is equal to the ratio of the enthalpy of fusion consumed at room temperature to the enthalpy of fusion of the pasty fat. The enthalpy of fusion of a fat in a paste form is the enthalpy consumed by the fat to change from a solid to a liquid state. A fat in a paste form is said to be in a solid state when its entire mass is in crystalline solid form. A fat in a paste form is said to be in a liquid state when its entire mass is in liquid form. The enthalpy of fusion of a fat-based substance is the amount of energy required to change the fat-based substance from a solid to a liquid state. It is expressed in J / g. The enthalpy of fusion of the fat-based substance is equal to the energy generated under the curve of the resulting thermogram.

[0259] The paste compound may in particular be chosen from synthetic paste compounds and fats of vegetable origin.

[0260] The paste compound(s) may in particular be selected from: - lanolin and its derivatives, such as lanolin alcohol, oxyethylenated lanolins, acetylated lanolin, lanolin esters such as isopropyl lanolate, oxypropylenated lanolins; - Vaseline (also called petrolatum), - C2-C4 pentaerythritol and polyalkylene glycol ethers, for example, compounds with the following INCI names: PEG-5 Pentaerythrityl Ether, PPG-5 Pentaerythrityl Ether, and mixtures thereof. One example is the mixture marketed under the name Lanolide by the company Vevy, - Liposoluble polyethers resulting from the polyetherification of one or more C2-C10 diols, preferably C2-C50.

[0261] If the composition includes at least one paste compound, its content varies from 0.5 to 20% by weight, and preferably from 1 to 15% by weight, relative to the total weight of the composition. Lipophilic thickeners

[0262] The composition according to the invention may also include at least one lipophilic thickener, chosen more particularly from among silicas, treated hydrophobically or not; lipophilic clays; alone or in mixture. It should be noted that lipophilic thickeners are not considered, within the meaning of the invention, as fillers. Silicas

[0263] The composition according to the invention may thus include, as a mineral thickener, a fumed silica, preferably hydrophobic, or silica aerogel particles, preferably hydrophobic. Pyrogenated silica

[0264] Suitable for the invention is hydrophobically treated fumed silica. It is indeed possible to chemically modify the surface of silica by a chemical reaction that reduces the number of silanol groups present on the silica surface. In particular, silanol groups can be replaced by hydrophobic groups, resulting in hydrophobic silica.

[0265] Hydrophobic groups can be: - trimethylsiloxyl groups, which are notably obtained by treating fumed silica in the presence of hexamethyldisilazane. Silicas treated in this way are called "Silica Silylate" according to the CTFA (8th edition, 2000). They are by examples marketed under the references Aerosil R812® by the company Degussa, CAB-O-SIL TS-530® by the company Cabot. - Dimethylsilyloxyl or polydimethylsiloxane groups, which are obtained in particular by treating fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas treated in this way are called "Silica Dimethyl Silylate" according to the CTFA (8th edition, 2000). They are marketed, 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

[0266] Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air.

[0267] They are generally synthesized by the sol-gel process in a liquid medium and then dried, usually by extraction from a supercritical fluid, most commonly supercritical CO2. This type of drying prevents contraction of the pores and the material. The sol-gel process and the various drying methods are described in detail in Brinker CL, and Scherer GW, Sol-Gel Science: New York: Academie Press, 1990.

[0268] Hydrophobic silica aerogel particles usually have a specific surface area per unit mass (SM) of 500 to 1500 m2 / g, preferably 600 to 1200 m2 / g and better 600 to 800 m2 / g, and a size expressed as volume mean diameter (D[0,5]) of 1 to 1500 pm, better 1 to 1000 pm, preferably 1 to 1000 pm, in particular 1 to 30 pm, preferably still 5 to 25 pm, better 5 to 20 pm and better still 5 to 15 pm.

[0269] According to one embodiment, the hydrophobic silica aerogel particles used in the present invention have a size expressed in volume average diameter (D[0,5]) ranging from 1 to 30 pm, preferably from 5 to 25 pm, better from 5 to 20 pm and even better from 5 to 15 pm.

[0270] The specific surface area per unit mass can be determined by the nitrogen absorption method known as the BET (BRUNAUER-EMMET-TELLER) method, described in "The Journal of the American Chemical Society", Vol. 60, Page 309, February 1938, and corresponding to the international standard ISO 5794 / 1 (Annex D). The BET specific surface area corresponds to the total specific surface area of ​​the particles considered.

[0271] The particle sizes of silica aerogel can be measured by static light scattering using a commercial particle size analyzer such as the Malvern MasterSizer 2000. The data are processed based on Mie scattering theory. This theory, accurate for isotropic particles, allows for the determination of an "effective" particle diameter in the case of non-spherical particles. This theory is notably described in the work of Van de Hulst, HC, “Light Scattering by Small Particles,” Chapters 9 and 10, Wiley, New York, 1957.

[0272] According to an advantageous embodiment, the hydrophobic silica aerogel particles used in the present invention have a specific surface area per unit mass (SM) ranging from 600 to 800 m2 / g and a size expressed in volume mean diameter (D[0,5]) ranging from 5 to 20 pm and even better from 5 to 15 pm.

[0273] Aerogels are hydrophobic silica aerogels, preferably silylated silica (INCI name Silica Silylate).

[0274] By "hydrophobic silica" is meant any silica whose surface is treated with silylation agents, for example with halogenated silanes such as alkylchlorosilanes, siloxanes, in particular dimethylsiloxanes such as hexamethyldisiloxane, or silazanes, so as to functionalize the OH groups with Si-Rn silyl groups, for example trimethylsilyl groups.

[0275] Regarding the preparation of surface-modified hydrophobic silica aerogel particles by silylation, reference can be made to US document 7,470,725.

[0276] Preferably, hydrophobic silica aerogel particles modified on the surface by trimethylsilyl groups will be used.

[0277] As examples of hydrophobic silica aerogels that can be used in the invention, we can cite, for instance, the aerogel marketed under the name VM-2260 (INCI name Silica silylate), by the company Dow Corning, whose particles have an average size of about 1000 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g.

[0278] We can also mention the aerogels marketed by the Cabot company under the references AEROGEL TLD 201, AEROGEL OGD 201, AEROGEL TLD 203, ENOVA® AEROGEL MT 1100, ENOVA AEROGEL MT 1200.

[0279] We can also mention T aerogel marketed under the name VM-2270 (INCI name Silica Silylate), by the company Dow Corning, whose particles have an average size ranging from 5-15 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g. Lipophilic clays

[0280] The term “lipophilic clay” means any clay that is liposoluble or lipodispersible in the oily phase of the composition.

[0281] Clay refers to a material based on hydrated silicates and / or aluminosilicates with a lamellar structure.

[0282] Clays can be natural or synthetic and are made lipophilic by treatment with an alkyl ammonium salt such as ammonium chloride (ClO₄)₂ at C22, in particular steralkonium chloride or di-stearyl di-methyl ammonium chloride.

[0283] They can be chosen from among bentonites, in particular bentonites, hectorites and montmorillonites, beidellites, saponites, nontronites, sepiolites, biotites, attapulgites, vermiculites and zeolites.

[0284] Preferably, they are chosen from among the hectorites and the bentonites.

[0285] For example, a lipophilic clay chosen from among the bentonites can be used hydrophobic modified and hydrophobic modified hectorites, notably by a quaternary ammonium chloride in C22-ClO, such as: - a bentonite modified by stearalkonium chloride such as the commercial products sold under the name Claytone AF®, Garamite VT®, Viscogel® LG-M, Viscogel® MP 250 Viscogel® VZ, Viscogel® VZ-V XR, by the company BYK Additives Inc; the commercial products sold under the name Viscogel® B3, Viscogel® B4, Viscogel® B7, Viscogel ® B8, Viscogel® ED, Viscogel® GM, Viscogel® S4, Viscogel® SD by the company Bentec SPA; - a bentonite modified by stearalkonium chloride in the presence of at least propylene carbonate and at least one oil such as the commercial products DUB VELVET GUM® from STEARINERIE DUBOIS FILS, MYGLYOL GEL T® from Cremer Oleo, Tixogel® CGT 6030, Tixogel ® DBA 6060, Tixogel ® FTN, Tixogel ® FTN 1564, Tixogel ® IPM, Tixogel ® LAN, Tixogel ® LAN 1563 by BYK Additives Inc; - a hectorite modified by distearyl dimethyl ammonium chloride (INCI name: Disteardimonium Hectorite) such as, for example, that marketed under the name Bentone® 38VCG Rheological Additive by the company Elementis Specialities; - a hectorite modified by distearyl dimethyl ammonium chloride in the presence of at least propylene carbonate or triethyl citrate and at least one oil such as the commercial products sold under the name Bentone® Gel DOA V, Bentone® Gel EUG V, Bentone® Gel IHD V, Bentone® Gel ISD V, Bentone® Gel MIO V® Bentone® Gel PTM V®, Bentone® SS-71 V, Bentone® VS-5 PC V, Bentone® VS-5 by the company Elementis Specialities; the commercial products sold under the name Creagel Bentone CPS / Hectone CPS, Creagel Bentone ID / Hectone ID by the company Créations Couleurs; the commercial products sold under the name NS GEL DM1®, NS GEL PTIS®, NS MGEL 1152® by the company Next Step Laboratories Stop.

[0286] Preferably, the lipophilic thickener may be present in the composition at concentrations ranging, preferably from 0.1% to 5% by weight, and more preferably from 0.5% to 3% by weight relative to the total weight of the composition.
