Description

Title of the invention: Aqueous composition comprising a solid monoester with at least 40 carbon atoms, a mixture of solid monoesters of C14-C18 fatty acid, a vegetable wax and a neutralized fatty acid salt Technical field

[0001] The present invention relates to the field of care and / or makeup of keratin fibers, and aims to propose compositions more particularly dedicated to makeup of eyelashes or eyebrows.

[0002] Generally speaking, compositions dedicated to the makeup of keratin fibers, for example eyelashes, aim to densify the thickness and visual perception of the eyelashes and ultimately the look. These mascaras are described as aqueous or cream mascaras, when they are formulated in aqueous base and anhydrous mascaras when they are formulated in the state of dispersion in an organic solvent medium.

[0003] A wide variety of cosmetic effects can be achieved by applying mascara to keratin fibers, particularly eyelashes, such as, for example, a loading, lengthening, thickening, and more particularly volumizing makeup effect.

[0004] These effects are essentially adjusted through the quantity and nature of the particles and particularly those of the waxes present in the mascaras. Generally speaking, mascaras in fact have a significant quantity of wax(es) and in particular from 10 to 35% by weight of waxes, more generally from 15 to 30% by weight, relative to their total weight.

[0005] For obvious reasons, the improvement of mascara textures which condition the manifestation of one or more makeup effects such as eyelash volume is a constant concern of the cosmetic formulator.

[0006] Consumers are also increasingly looking for cosmetic products made, in whole or in part, from natural or naturally derived constituents, and preferably of plant origin, whether for reasons of better skin tolerance, environmental protection, sustainable development or biodiversity.

[0007] By "natural compound" is meant a compound that is obtained directly from the earth or soil, or from plants or animals, via, where appropriate, one or more physical processes, such as for example grinding, refining, distillation, purification or filtration.

[0008] By compounds “of natural origin” is meant a natural compound which has undergone one or more additional chemical or industrial treatments, resulting in modifications not affecting the essential qualities of this compound and / or a compound comprising mainly natural constituents which may or may not have undergone transformations. As a non-limiting example of an additional chemical or industrial treatment resulting in modifications which do not affect the essential qualities of a natural compound, we can mention those authorized by control bodies such as Ecocert (Reference for organic and ecological cosmetic products, January 2003) or defined in recognized manuals in the field, such as “Cosmetics and Toileries Magazine”, 2005, vol. 120, 9: 10.

[0009] Patent applications FR3080034A1 WO2019 / 201930A1, WO2019 / 201931A1 and WO2020 / 127981A1 disclose mascara compositions, in particular in the form of a wax / water emulsion, which may consist of ingredients of natural plant origin, namely at least one solid monoester of fatty acid with a total number of carbon atoms greater than or equal to 40, in particular behenyl behenate, at least one fatty acid having from 14 carbon atoms to less than 20 carbon atoms, at least one base capable of at least partially neutralizing said fatty acid, and water.

[0010] We know of mascaras currently on the market which are wax-in-water emulsions with a significant quantity of beeswax of animal origin and wax of mineral origin such as paraffin and behenyl behenate. Some of these compositions tend to give products with a grainy appearance which is unattractive and can have an impact on the expected performance on the eyelashes.

[0011] There remains a need to produce new mascara formulas in the form of a wax / water emulsion comprising a mixture of fatty acid monoester and natural or naturally derived waxes making it possible to obtain good makeup performance such as volume without observing a granular effect.

[0012] The applicant, during its research, unexpectedly discovered that the objectives as defined above were achieved by using a composition for caring for and / or making up keratin fibres, in particular eyelashes and eyebrows, comprising, in particular in a physiologically acceptable medium: (1) at least one solid monoester of linear fatty acid comprising a total number of carbon atoms greater than or equal to 40 of the following formula (I): [Chem 1] R1-O-R2 (I) in which R1 and R2 are linear and saturated and have, independently of each other, a number of carbon atoms greater than or equal to 20, with R1 representing an acyl radical, and R2 representing an alkyl radical, and (2) at least one mixture of solid monoesters of C14-C18 carboxylic acid and a C10 fatty alcohol; and (3) at least one vegetable wax; and (4) at least one fatty acid having from 14 carbon atoms to less than 20 carbon atoms, and (5) at least one base capable of at least partially neutralizing said fatty acid, and (6) water.

[0013] Unexpectedly, the inventors have in fact found that the formulation comprising at least one solid monoester of linear fatty acid (1), at least one mixture of solid monoesters of fatty acid (2), at least one natural vegetable wax (3), at least one fatty acid having from 14 carbon atoms to less than 20 carbon atoms (4) in form neutralized by a base (5) and water (6), makes it possible to obtain compositions producing good makeup properties on the eyelashes, in particular a good volumizing effect without observing a granular appearance.

[0014] This discovery is the basis of the invention. Objects of the invention

[0015] Thus, according to one of its aspects, the present invention relates to a composition for caring for and / or making up keratin fibres, in particular eyelashes and eyebrows, comprising, in particular in a physiologically acceptable medium: (1) at least one solid monoester of linear fatty acid of the following formula (I): [Chem 1] R1-O-R2 (I) in which Ri and R2 are linear and saturated and have, independently of each other, a number of carbon atoms greater than or equal to 20, with Ri representing an acyl radical, and R2 representing an alkyl radical, and (2) at least one mixture of solid monoesters of C14-C18 carboxylic acid and a C10 fatty alcohol; (3) at least one vegetable wax; and (4) at least one fatty acid having from 14 carbon atoms to less than 20 carbon atoms, and (5) at least one base capable of at least partially neutralizing said fatty acid, and (6) water.

[0016] According to a preferred embodiment, the compositions according to the invention do not comprise animal wax or mineral wax.

[0017] The term “solid fatty acid monoester” means any organic compound comprising only one ester function in its structure and which is solid at room temperature (25°C) and atmospheric pressure (760 mm Hg).

[0018] The term “waxes” means lipophilic compounds, solid at room temperature (25°C) and at atmospheric pressure (760 mm Hg), with a reversible solid / liquid state change, having a melting point greater than or equal to 40°C and up to 120 °c.

[0019] By “mineral wax” is meant any wax of natural or synthetic origin

[0020] A second object of the present invention is a cosmetic process for making up and / or caring for keratin fibers, consisting of applying to said keratin materials a composition as defined above. Definitions

[0021] In the context of the present invention, the term "keratin fiber" is understood to mean eyelashes and eyebrows. This term "keratin fibers", within the meaning of the present invention, also extends to synthetic false eyelashes.

[0022] By "physiologically acceptable" is meant compatible with the skin and / or its appendages, which has a pleasant color, odor and feel and which does not generate unacceptable discomfort (tingling, tightness), likely to deter the consumer from using this composition.

[0023] According to a preferred embodiment, the compositions according to the invention do not contain animal wax or mineral wax.

[0024] By composition not containing animal wax or mineral wax, is meant any composition comprising less than 5% by weight in total quantity of animal wax and mineral wax, or even less than 2% by weight, more particularly less than 1% by weight, even more particularly less than 0.5% by weight relative to the total weight of the composition, or even said composition is free from such waxes.

[0025] The term “waxes” means lipophilic compounds, solid at room temperature (25°C) and at atmospheric pressure (760 mm Hg), with a reversible solid / liquid state change, having a melting point greater than or equal to 40°C up to 120°C.

[0026] By "animal wax" is meant any wax derived partly or totally from an animal. Examples include beeswax, Ghedda wax, shellac, Chinese wax, lanolin also called wool wax, their mixtures and their derivatives.

[0027] By "mineral wax" is meant any natural or synthetic hydrocarbon-based wax consisting solely of carbon atoms and hydrogen atoms. Among the natural mineral waxes, we can notably cite so-called fossil waxes including those of petroleum origin such as lignite, ozocerite, pyropissite, macrocrystalline waxes also called paraffins - including crude waxes or slack wax, slack wax raffinates, deoiled slack wax, soft waxes, semi-refined waxes, filtered waxes, refined waxes - and microcrystalline waxes called microwaxes including slack wax from "bright stock"

[0028] Among the synthetic mineral waxes, mention may be made of semi-synthetic waxes and fully synthetic waxes. The synthetic waxes may be waxes obtained by a Fischer-Tropsch process, consisting for example of paraffins with a number of carbon atoms ranging from 20 to 50 or polyolefin waxes, for example homo- or copolymers of ethylene, propene or butene, or even longer chain α-olefins. The latter can be obtained by thermomechanical degradation of plastic polyethylene, by the Ziegler process, by high-pressure processes, or via processes catalyzed by metallocene species. These waxes can be crystallizable, partially crystallizable or amorphous. The aforementioned synthetic waxes are generally apolar and can be chemically treated to obtain polar waxes, for example by one or more of the following reactions: air oxidation, grafting, esterification, neutralization by metal soaps, amidation, direct copolymerizations or addition reactions.
