Description

1 This application relates to the field of make-up or skincare

  eyelashes or mascaras. The eyelash coating compositions such as mascaras are generally makeup compositions, compositions for applying to a make-up (also called top-coat), or cosmetic eyelash care compositions. Mascaras are especially prepared according to two types of formulation: aqueous mascaras called cream mascaras, in the form of dispersion of waxes in water; anhydrous mascaras or low-water mascaras, in the form of dispersions of waxes in organic solvents.

  The present application relates more specifically to aqueous mascaras. The application of mascara makes it possible to increase the volume of the eyelashes and consequently to increase the intensity of the gaze. For this, there are many thickening or volumizing mascaras whose principle is to deposit the maximum material on the eyelashes so as to obtain a volumizing effect (or charging).

  It is in particular through the quantity of solid particles (in particular waxes which make it possible to structure the composition) that the desired application specificities for the compositions can be adjusted, for example their fluidity or consistency, as well as their thickening power (also called power charging or makeup). These solid particles are dispersed in the cream mascara using a surfactant system. Among the emulsifiers or conventional emulsifying systems, there are emulsifying systems based on triethanolamine stearate.

  The problem posed in the present application is to propose a mascara in which not only the waxes but also the pigments are homogeneously dispersed, said mascara having a sufficiently thick texture to obtain a charging deposit, volumizing on the eyelashes, and having a consistency satisfactory allowing easy application to the eyelashes and a smooth and homogeneous deposit.  Surprisingly and unexpectedly, the inventors of the present application solved this problem by means of an emulsifying system comprising at least one lactic acid derivative and / or one of its salts.  The inventors of the present application have observed that the emulsifying system defined in the present application allows a good dispersion of the pigments and / or waxes, this dispersion is of the quality of those obtained with the emulsifying systems based on stearate. triethanolamine.  This composition makes it possible to obtain a make-up loading the eyelashes and a satisfactory consistency compatible with obtaining a smooth and homogeneous deposit on said fibers.  The compositions according to the invention may have a viscoelastic behavior.  In general, a material is said to be viscoelastic when, under the effect of shearing, it has both the characteristics of an elastic material, ie capable of storing energy and the characteristics of a material. viscous material, ie able to dissipate energy.  The viscoelastic behavior of the compositions according to the invention may be more particularly characterized by its rigidity modulus G.  This parameter is defined in particular in the book "Initiation à la rheologie", G.  Couarraze and J. L.  Grossiord, 2nd edition, 1991, Edition Lavoisier-Tec 1 Doc.  The measurements are carried out on an imposed stress rheometer, RS 600 from ThermoRheo, equipped with a thermostatic bath and a stainless steel mobile with a cone / plane geometry, with a diameter of 35 mm and an angle of 2.  Both surfaces are sandblasted to limit slippage to the walls.  The measurements are made at 25 ° C.  The dynamic measurements are made by applying a harmonic variation of the stress.  In these experiments, the amplitudes of the shear stress (denoted r) and the shear strain (denoted y) are small so as to remain within the limits of the linear viscoelastic domain of the composition (conditions making it possible to evaluate the rheological characteristics resting composition).  The viscoelastic linear domain is generally defined by the fact that the response of the material (i. e.  the deformation) is at any moment directly proportional to the value of the applied force (i. e.  the constraint).  In this field, the applied stresses are small and the material undergoes deformations without modifying its microscopic structure.  Under these conditions, the material is studied at rest and non-destructively.  The composition is subjected to harmonic shear according to a stress' r (t) sinusoidally varying in a w (w = 2flv) pulsation, where v is the applied shear frequency.  The composition thus sheared undergoes a stress' r (t) and responds to a deformation y (t) corresponding to micro-deformations for which the modulus of rigidity varies little as a function of the imposed constraint.  The stress r (t) and the strain y (t) are respectively defined by the following relations: ## EQU1 ## where ro is the maximum amplitude of the stress and yo is the maximum amplitude of the strain.  Elasticity b is the phase shift angle between stress and strain.  The measurements are made at a frequency of 1 Hz (v = 1 Hz).  Increasing stresses are applied to the sample starting from an initial stress equal to 0.01 Pa to arrive at a final stress of 1000 Pa, the stresses being applied only once.  The evolution of the modulus of rigidity G (corresponding to the ratio of 'ro over 20 yo) and of the elasticity b (corresponding to the phase shift angle of the stress applied with respect to the measured strain) is thus measured as a function of the constraint 'r (t) applied.  In particular, the deformation of the composition is measured for the stress zone in which the variation of modulus of rigidity G and of elasticity b is less than 7% (zone of microdeformations) and the parameters known as plateaux Gp 25 and bp.  The composition has, for example, a modulus of plateau rigidity Gp greater than or equal to 10 Pa, preferably greater than or equal to 50 Pa, up to 106 Pa and better up to 5. 106Pa.  A first object of the present application is a cosmetic composition for coating the eyelashes comprising an aqueous phase and an emulsifying system comprising at least one lactic acid derivative and / or one of its salts, as the main surfactant system of the composition.  According to one variant, the subject of the invention is a cosmetic composition for coating the eyelashes comprising an aqueous phase and an emulsifying system comprising at least one lactic acid derivative and / or one of its salts, said composition comprising less than 1% triethanolamine.  Another object of the present application is a method of non-therapeutic make-up or care of the eyelashes comprising applying to said eyelashes the composition according to the present application.  Another object of the present application relates to the uses of the composition according to the present application, in particular the use of this composition to obtain a homogeneous makeup and / or volumizer eyelashes.  Other characteristics, properties and advantages of the present invention will emerge more clearly on reading the description and examples which follow.  Emulsifying system The emulsifying system of the composition according to the invention comprises at least one lactic acid derivative and / or a salt of said derivative.  The lactic acid derivative or its salt may be chosen from acyl lactylic acid derivatives, their salts (lactylates) and their mixtures, such as the compounds of the following formula: ## STR2 ## wherein R represents an acyl group O = CR ', R' being a linear or branched, saturated or unsaturated hydrocarbon-based chain preferably comprising from 10 to 30 carbon atoms, preferably from 12 to 22 carbon atoms, preferably from 14 to 22 carbon atoms;
