Description

STABILIZED COSMETIC COMPOSITION COMPRISING AT LEAST ONE MONOMER

  The present invention relates to a stabilized composition based on monomers having a cyanoacrylate function, an organic solvent and a zinc oxide.

  There are many styling products that can bring body, mass or volume to the hair. A disadvantage related to these products, most often based on film-forming polymers, lies in the fact that the cosmetic effect disappears from the first shampoo.

  It is theoretically possible to increase the remanence of the polymer deposit by directly effecting a radical polymerization of certain monomers in the hair. However, the treatments thus obtained are unacceptable from the cosmetic point of view. There is generally a strong degradation of the fiber probably related to the polymerization initiators and the treated hair is difficult to disentangle.

  As of today, there are no cosmetic compositions that make it possible to provide body, mass or volume in a sustainable manner to the hair. The Applicant has just discovered that it is possible to obtain an improvement in the body, mass or volume of the hair and this in a sustainable manner, by using cyanoacrylate monomers as described in the application for patent FR2833489 and a stabilized zinc oxide. The Applicant has found more particularly that by applying a stabilized composition based on such monomers and zinc oxide on the hair, it forms in situ a remanent coating. Without this explanation being limiting, it seems that it is the hydroxide ions contained in the water absorbed by the hair which initiate the process of anionic polymerization at the interface treatment-hair composition. The polymer thus formed in situ by interfacial anionic polymerization is in the form of a homogeneous, smooth deposit and has excellent adhesion to hair. On the other hand, it has surprisingly been found that the hair remains perfectly individualized, can be capped without problems and that the styling properties provided to the fiber are remanent to the shampoos. Depending on its characteristic and its concentration, the zinc oxide added may make it possible to reinforce the resistance of the sheathing against certain external aggressions and in particular its resistance to fatty substances such as sebum. The invention firstly relates to a stabilized cosmetic composition comprising at least one polymerizable cyanoacrylate monomer, at least one zinc oxide, at least one liquid organic solvent. The subject of the invention is also a cosmetic treatment method using the composition cosmetic according to the invention. Another object of the present invention is the use of the cosmetic composition for the treatment of hair. In particular, the invention relates to a use of the cosmetic composition for conditioning hair. More particularly, the invention relates to a use of the cosmetic composition for hair dyeing.
