Definitions
- the invention relates to the field of aqueous dispersions of polymers used in cosmetic compositions. It relates in particular to aqueous dispersions of film-forming polymer without coalescing solvent and their use in make-up formulations such as nail varnishes, bases for nail varnishes, mascaras or lipsticks. It also relates to the use of these aqueous film-forming dispersions in formulations for caring for the hair, for example for gels or styling foams.
- aqueous nail varnishes described in the prior art contain as film-forming substance copolymers in solution in water or dispersed in the form of a latex.
- copolymers are obtained by radical polymerization of vinyl, acrylic and / or styrene monomers.
- US Patent 4,158,053 describes for example nail varnish formulations comprising a copolymer of acrylic and / or styrene monomers whose glass transition temperature (Tg) is between - 10 ° C and 50 ° C.
- Tg glass transition temperature
- the properties of the varnishes obtained are not entirely satisfactory. If the copolymers used have a Tg lower than the nail temperature, the varnishes have superficial stickiness. If their Tg is higher than the temperature of the nail, it is necessary to incorporate plasticizers in the formulation to obtain good film-forming after application.
- EP 679384 and JP 09071512 also describe aqueous compositions for nail varnish comprising film-forming polymers in the presence of high levels of plasticizers.
- nail varnishes An important property sought for nail varnishes is the impression of dryness to the touch in less than 10 minutes after application.
- plasticizers present in nail varnishes often have high boiling temperatures. They therefore evaporate slowly and the varnishes remain sticky for a long time.
- the first way consists in mixing two latexes of different Tg, one having a Tg lower than the ambient temperature and the other, having a Tg higher than the ambient temperature.
- This route is described, for example, in JP 06298624, JP 1 1209244 and FR 2718350 for compositions for nail varnish and in EP 909157 for cosmetic compositions for hair care or eye makeup. After drying of such compositions, a decrease in gloss of the films is often observed due to the incompatibility between the various constituents of the mixture as well as a low resistance to water which results in bleaching of the films.
- the second route consists in using a polymer dispersion comprising at least one internal phase of Tg greater than 30 ° C and at least one external phase of Tg between -15 ° C and 35 ° C.
- a polymer dispersion comprising at least one internal phase of Tg greater than 30 ° C and at least one external phase of Tg between -15 ° C and 35 ° C.
- coalescing agents such as alkyl glycols which evaporate slowly.
- the solutions currently known are therefore not entirely satisfactory insofar as the aqueous compositions proposed always contain non-negligible amounts of co-solvent or plasticizers which, on the one hand, are toxic and, on the other hand, cause the varnishes to dry slowly after application.
- the problem remaining to be resolved is therefore the preparation of a cosmetic composition containing little or no solvent, drying quickly and leading to a hard, non-sticky film, resistant to abrasion and capable of being easily removed.
- a cosmetic formulation of aqueous dispersions of polymer particles comprising at least one internal phase formed by a polymer with a soft character of glass transition temperature below 20 ° C., and at least one external phase formed by a polymer with a hard character of glass transition temperature greater than 40 ° C. makes it possible to obtain varnishes with little or no solvent, easily applicable, in particular on the nails. These varnishes dry in less than ten minutes and lead to homogeneous, shiny, non-sticky films with good abrasion resistance. Depending on the chemical composition of the particles, these varnishes can be peeled or easily removed with a conventional solvent such as acetone.
- the object of the present invention is therefore a cosmetic composition, in particular a composition for nail varnish, which contains such aqueous dispersions of polymers and cosmetic additives known to those skilled in the art, such as anti-foaming agents, wetting agents, thickeners, colorants, fillers, perfumes, etc.
- the cosmetic compositions according to the invention can be used as a base for varnishes, as a colorless or tinted varnish, and / or as base for nail care, skin care and / or hygiene, hair wash and conditioning care. They can also be used to obtain a film which can be peeled.
- compositions for obtaining films peelable according to the invention also limits the use of solvents such as those present in conventional solvents
