MASCARA COMPOSITION WITH A TETRAHYDROXYPROPYLETHYLENE DIAMINE ESTER

Description

[0001] The present application relates to the field of makeup or eyelash care, in particular to the field of cream mascaras and more specifically concerns a cosmetic composition applicable to keratin fibers.

[0002] The invention relates more specifically to a mascara containing a high quantity of waxes emulsified in an aqueous phase with a fatty acid ester and tetrahydroxypropyl ethylene diamine (THPE). STATE OF THE ART

[0003] Wax-in-water mascaras containing triethanolamine esters (TEA) such as triethanolamine stearate are known for their smooth, creamy, and luscious application. Triethanolamine esters are formed during the mascara preparation process by reacting an acid or a mixture of fatty acids with triethanolamine.

[0004] However, TEA poses a high risk of nitrosamine formation during storage and use of mascara in packaging. TEA can react with packaging components to release nitrosamines such as NDELA (N-nitrosodiethanolamine), so its use in many products is regulated. Cosmetic products, for example, must have an NDELA content of less than 10 ppb to comply with regulations in major European countries.

[0005] Several proposals for partial or total substitution of TEA with other hydroxylated amines to form fatty acid esters have been developed, but the resulting mascaras have drawbacks.

[0006] This is particularly the case for wax-in-water mascaras containing aminomethyl propanediol (AMPD) esters, which are less creamy and drier on application when the TEA is completely replaced by AMPD. Such formulas are, for example, described in EP 3 228 304.

[0007] Other amines such as tromethamine have also been evaluated, but attempts to replace TEA with these amines have not resulted in its complete removal from formulas while maintaining a satisfactory makeup result.

[0008] US 2003 / 224025 and US 2006 / 165620 describe wax-in-water waterproof mascaras comprising stearic acid and 1.3% by mass of tetrahydroxypropyl ethylene diamine.

[0009] There is therefore a continuing need for wax-in-water emulsion cream mascaras containing fatty acid esters that are unlikely to release nitrosamines during their shelf life and that have a creamy texture upon application.

[0010] More specifically, we are looking for a mascara free from triethanolamine esters which has application qualities at least equivalent to those of mascaras containing them, and which do not suffer from the disadvantages of those which have been developed by substituting triethanolamine.

[0011] The inventors surprisingly found that esters of fatty acids and tetrahydroxypropyl ethylene diamine formulated in wax-in-water emulsions make it possible to obtain smooth and creamy products that are pleasant to use without the risk of releasing nitrosamines.

[0012] Tetrahydroxypropyl ethylenediamine fatty acid esters can completely substitute triethanolamine esters in existing architectures while retaining the same properties or even improving some of them.

[0013] In particular, it has been discovered that esters of fatty acids and tetrahydroxypropyl ethylene diamine make it possible to offer new mascara textures, original in their sensoriality, their application qualities and their makeup results.

[0014] The texture may be more fluid, which makes the application more gliding and more pleasant. Although the emulsion is more fluid, the eyelash load remains equivalent, which is very surprising.

[0015] The formula can also be more adherent which improves the hold of the product on the eyelashes over time.

[0016] Finally, the composition allows for deeper shades, including more intense blacks.

[0017] Tetrahydroxypropyl ethylenediamine has been incorporated into cosmetic compositions in low concentrations to perform the pH adjustment function. However, in these compositions, tetrahydroxypropyl ethylenediamine cannot form the significant amounts of esters needed in emulsion mascaras to stabilize waxes in an aqueous phase. DESCRIPTION OF THE INVENTION

[0018] The invention therefore relates to a cosmetic composition for care or makeup of the eyelashes or eyebrows comprising waxes in emulsion in an aqueous phase and at least one ester obtained by reaction of a linear and saturated fatty acid comprising from 16 to 20 carbon atoms, and tetrahydroxypropyl ethylene diamine, the fatty acid representing from 2.0 to 8.0% by mass and the amine representing from 3.0 to 8.0% by mass, and the molar ratio between the fatty acid and the amine being between 0.9 and 5. The fatty acid represents from 2.0 to 8.0% by mass, preferably from 2.5 to 5.0% by mass, and more preferably from 4.0 to 6.0% by mass, relative to the mass of the composition.

[0019] The amine represents from 3.0 to 8.0% by mass, preferably from 3.0 to 7.0% by mass, more preferably from 3.0 to 6.0% by mass, and even more preferably from 3.0 to 4.5% by mass, relative to the mass of the composition.

[0020] The molar ratio between the linear and saturated fatty acid and the tetrahydroxypropyl ethylene diamine is preferably between 0.9 and 4.0, preferably between 1.0 and 3.0, and more preferably between 1.1 and 2.0. It is preferred to use the fatty acid in excess so that it contributes to the structuring of the fatty phase.

[0021] In this description, the mass percentages are expressed relative to the mass of the emulsion unless otherwise stated.

[0022] The composition preferably comprises less than 1% by mass of a compound or mixture of compounds selected from a triethanolamine ester, an aminomethyl propanediol ester, and a tromethamine ester, which are likely to adversely affect the performance of the mascara.

[0023] The invention also describes a cosmetic composition for caring for or making up eyelashes or eyebrows in the form of a wax-in-water emulsion comprising a quantity of compounds carrying an amine function capable of decomposing into nitrosamines in an amount of less than 10 ppb, characterized in that it comprises a linear and saturated fatty acid ester having from 16 to 20 carbon atoms and tetrahydroxypropyl ethylene diamine, said ester being in a quantity sufficient to obtain a viscosity whose value is at least 20% lower than the viscosity of an identical composition comprising a fatty acid ester and an amine chosen from triethanolamine, tromethamine and aminopropane diol.

[0024] The composition is advantageously free of esters of a linear and saturated fatty acid with an amine chosen from triethanolamine, aminopropanediol and tromethamine.

[0025] The linear and saturated fatty acid may be stearic acid, palmitic acid or behenic acid. According to one embodiment, a mixture of stearic acid and palmitic acid is used, for example in a mass ratio of between 80 / 20 and 20 / 80, and advantageously in the mass ratio 50 / 50. A particular embodiment comprises the equal-weight mixture of stearic acid and palmitic acid.

[0026] Tetrahydroxypropyl ethylenediamine has the IUPAC nomenclature N,N,N',N'-Tetrakis(2-hydroxypropyl)ethylenediamine and the INCI name TETRAHYDROXYPROPYL ETHYLENEDIAMINE. It is sold under the brands NEUTROL ®< TE, LUTROPUR ®< Q75 from BASF, and ADEKA CARPOL ®< MD100 from ADEKA.

[0027] The amount of the fatty acid ester of tetrahydroxypropyl ethylene diamine is preferably sufficient to achieve a percentage decrease in the viscosity of the mascara greater than a value selected from the group consisting of 10%, 15%, 20%, 25%, 30%, 35% and 40%, compared to a mascara of identical composition in which the tetrahydroxypropyl ethylene diamine ingredient used to manufacture the mascara is replaced by triethanolamine.

[0028] The composition according to the invention has a fluid texture: its viscosity is preferably less than 250,000 mPa.s, for example between 150,000 mPa.s and 230,000 mPa.s, preferably between 140,000 mPa.s and 210,000 mPa.s. The viscosity of the composition can be measured at 25°C using a Rhéomat ®< 180 (LAMY Company) equipped with a MS-R1, MS-R2, MS-R3, MS-R4 or MS-R5 spindle chosen according to the consistency of the composition, rotating at a rotation speed of 200 rpm -1< . The measurement is taken after 10 min of rotation.

[0029] The THPE fatty acid ester serves as an anionic surfactant with an HLB greater than 8. In the present invention, the HLB values ​​are those of Griffin at 25°C.

[0030] It is possible to optionally combine it with at least one non-ionic surfactant whose HLB is less than 8, in particular when the quantity of waxes in the composition is greater than 20% by mass. This surfactant can be chosen from the group consisting of: esters and ethers of oses; esters of fatty acids, in particular C8-C24, and preferably C16-C22, and of polyol, in particular of glycerol or sorbitol, preferably of glycerol, such as glyceryl stearate; oxyalkylenated alcohols comprising less than 10 oxyalkylenated units, better still less than 5 oxyalkylenated units, in particular oxyethylenated and / or oxypropylenated.

[0031] An oxyethylenated alcohol comprising less than 5 oxyalkylenated units may be the compound with the INCI name STEARETH-2.

[0032] The composition may also contain a mixture of surfactants comprising the fatty acid ester and THPE, at least one non-ionic surfactant whose HLB is less than 8 as described above and at least one non-ionic surfactant with an HLB greater than 8. This combination is particularly advantageous when the level of waxes in the composition is greater than 30% by mass.

[0033] The latter can be chosen from: fatty alcohols comprising from 8 to 24 carbon atoms (such as stearyl alcohol) which comprise 20 oxyethylene units (INCI name STEARETH-20, the compound INCI name CETEARETH-30 and the compound INCI name PARETH-7), PEG-40 monostearate, fatty acid esters comprising 30 oxyethylene units, such as polyoxyethylene glyceryl stearate comprising 30 oxyethylene units, polyoxyethylene glyceryl oleate comprising 30 oxyethylene units, polyoxyethylene glyceryl cocoate comprising 30 oxyethylene units, polyoxyethylene glyceryl isostearate comprising 30 oxyethylene units, polyoxyethylene glyceryl laurate comprising 30 oxyethylene units, and polyoxyethylene sorbitan esters, such as polysorbate 60.

[0034] The composition may contain an anionic surfactant having an HLB value greater than or equal to 8, such as alkylphosphates and alkylsulfates. In a particular embodiment of the invention, the composition is free of them.

[0035] The surfactants preferably used in the composition according to the invention are chosen, for example, from oxyethylenated and / or oxypropylenated ethers, fatty acid and polyethylene glycol esters, polyethylene glycol / polypropylene glycol polycondensates, fatty acid and glycerol esters, such as glyceryl stearate, fatty acid and sorbitol esters, fatty acid and sorbitan esters, sucrose esters and sucrose ethers.

[0036] According to a particular embodiment, the composition contains a high quantity of wax(es), preferably between 15 and 25% by mass.

[0037] These particular compositions advantageously allow a lot of product to be deposited from the first pass of the brush on the eyelashes, to better coat the eyelashes, provide volume immediately perceptible by the user, and increase the hold of the makeup over time.

[0038] However, the prior art wax-in-water emulsions concentrated in waxes can lack fluidity, so that the quantity of product deposited on the eyelashes becomes too large and the coating of the eyelashes loses its homogeneity.

[0039] The introduction of linear fatty acid ester and tetrahydroxypropyl ethylene diamine into wax-in-water emulsions containing significant amounts of solid compounds such as waxes is therefore particularly advantageous, as it makes it possible to counterbalance the increase in consistency provided by these compounds by lowering the viscosity very significantly. In this type of architecture, the composition of the invention therefore makes it possible, in a very advantageous manner, to propose cream mascaras providing immediate volume, lengthening and very effective hold over time, after a smooth and homogeneous application of the product.

[0040] Any wax known to those skilled in the cosmetics field may be used. The wax may be chosen, for example, from: alkane waxes, also known as apolar, chosen from waxes obtained from petroleum distillation such as microcrystalline waxes and certain paraffin waxes; synthetic waxes obtained by polymerization of methylene, ethylene or propylene such as polymethylene wax, polyethylene wax, polypropylene wax, ethylene / propylene copolymer wax and ethylene / hexene copolymer wax; Fischer Tropsch waxes; ozokerite wax;and ceresin obtained by refining the preceding, silicone waxes, and waxes which are neither silicone nor alkanes also called polar, such as for example beeswax, rice bran wax, Carnauba wax, Candellila wax, Ouricurry wax, Japan wax, Berry wax, Sumac wax, Montan wax, Alfa wax, cork fiber wax, sugar cane wax, orange wax, lemon wax, laurel wax, waxes obtained by hydrogenation of animal or vegetable oils having linear or branched fatty chains, in C8-C32, such as jojoba oil, sunflower oil, castor oil, copra oil, lanolin oil, olive oil esterified with stearyl alcohol, castor oil esterified with cetyl alcohol.;

[0041] According to one embodiment of the invention, the waxes represent from 10 to 35% by mass, preferably from 15% to 35% by mass, more preferably from 18% to 28% by mass, relative to the mass of the composition.

[0042] In a particular embodiment, the composition contains a mixture of apolar wax and polar wax.

[0043] In another embodiment, the composition contains 10 to 20% by mass of a wax whose melting point is greater than or equal to 70°C. The melting point may be measured by any method known to those skilled in the art. For the purposes of the present invention, the term “melting temperature or melting point” of a compound means in particular one of the following quantities: the melting point corresponding to the start of the melting of this compound or the temperature corresponding to the endothermic peak of the compound, these quantities being able to be measured by DSC (Differential Scanning Calorimetry) according to the ISO 11357-3 standard.

[0044] A wax with a melting point greater than or equal to 70°C used in the context of the invention may be a paraffin wax with a melting point ranging from 62°C to 65°C, a candelilla wax, a beeswax or a carnauba wax with a melting point ranging from 78 to 85°C. The melting point varies depending on the manufacturing process of the wax and the method used to measure it.

[0045] The composition may contain in particular the mixture of at least one wax whose melting point is greater than or equal to 70°C and at least one wax whose melting point is less than 70°C, one of the waxes being an apolar wax and the other being a polar wax.

[0046] The composition may contain at least one polymer that acts as a texturizing, film-forming or gelling agent. The polymer may in particular be intended to increase the coating of the eyelashes, the lengthening of the eyelashes and / or their curling.

[0047] The amount of polymer may range from 2 to 20%, preferably from 3 to 10% by mass relative to the mass of the composition.

[0048] Possible polymers include polybutene, ethylcellulose and vinylpyrrolidone (VP) copolymers such as VP / eicosene or VP / hexadecene, hydrogenated polydecene, non-volatile silicone oils, including phenyl trimethicones, and mixtures thereof.

[0049] Among the polymers, we can also cite cellulose polymers such as hydroxyethylcellulose, vinyl polymers such as polyvinylpyrrolidones, gum arabic, guar gum, xanthan derivatives, aqueous dispersions of acrylate copolymers, and their mixtures.

[0050] The total amount of polymers and waxes in the composition is preferably between 15% and 35% of the composition.

[0051] The mascara composition comprises pigments representing from 5 to 20% by weight, for example from 8 to 15% by mass of the composition.

[0052] The pigments are preferably chosen from titanium dioxide, zinc oxides, iron oxides (black, yellow or red), manganese violet, ultramarine blue, chromium hydrate and ferric blue, metallic powders such as aluminum powder, copper powder. Among the organic pigments, mention may be made of carbon black, D & C type pigments, and lakes. Mention may also be made of reflective pigments and pearlescent pigments.

[0053] The liquid phase represents, for example, from 30% to 60% by mass, preferably from 40% to 55% by mass, relative to the mass of the mascara composition.

[0054] The liquid phase may contain water, volatile oils, and polyols such as butylene glycol. The oils may be selected from volatile dimethicones, cyclomethicones, isododecane, isohexadecane, or isodecane.

[0055] According to one embodiment of the invention, the liquid phase represents from 40% to 55% by weight, the waxes represent from 20% to 25% by weight, and the pigments represent from 8 to 12% by weight.

[0056] The compositions of the invention may contain, in addition to the ingredients described above, adjuvants usual in the field of mascara formulation, such as hydrophilic or lipophilic gelling agents, active ingredients, non-volatile oils, fatty compounds in paste form, preservatives, antioxidants, pH adjusters and perfumes.

[0057] Non-volatile oils can be chosen from paraffin oil, isotridecyl isononanoate, isostearyl neopentanoate, tridecyl neopentanoate, cetyl octanoate. It is preferred to use non-volatile oils of plant origin, such as castor oil, argan oil or almond oil, which can also serve as an active ingredient.

[0058] The description of the ingredients included in the composition of the invention can be supplemented by the content of application FR 2 996 767.

[0059] The invention is illustrated by the following examples. Example 1, Comparative Example 2 and Comparative Example 3:

[0061] To make a reliable comparison, the total amount of stearic acid and palmitic acid was kept constant for both trials, and the amount of THPE was adjusted to obtain an equal THPE / (fatty acids) molar ratio. Preparation process :

[0062] Prepare the aqueous phase A1, stir STARO in a water bath at 85°C.

[0063] Add the aqueous phase gelling agents A2 to A1 while stirring.

[0064] Prepare the fatty phase B1, place in a water bath at 85°C and stir STARO.

[0065] Once phase B1 has melted, add the mixture of pigments and fillers B2 to B1 while stirring, and disperse for 30 min.

[0066] Emulsify A in B with vigorous stirring in STARO at 85°C for 5 min then remove the water bath.

[0067] Allow to cool, gradually reducing stirring to 30°C. • Microscopic observations

[0068] The compositions of Example 1 and Comparative Example 2 were observed under a microscope at a magnification of 100. Figure 1 and the Figure 2 present the obtained photos.

[0069] The dispersions of both compositions are homogeneous, regular and fairly tight; the waxes and pigments are well dispersed.

[0070] THPE ester allows dispersions to be obtained as fine as those obtained with triethanolamine ester. • Viscosity and pH measurement Measurement method
