This recrystallization from the mixture may be responsible for the reduction in the gloss of said mixture.
• the composition contains little or no conventional waxes and in particular less than 10%, by weight, of conventional wax and better still less than 5% relative to the total weight of the composition.
• waxes in the sense of demand, are those generally used in the cosmetic and dermatological fields; they are in particular of natural origin such as beeswax, Candellila, Ouricoury, Japan, cork fibers or sugar cane, paraffin waxes, lignite, microcrystalline waxes of melting point> 50 ° C, lanolin wax, Montan wax, ozokerites, hydrogenated oils such as hydrogenated jojoba oil, but also of synthetic origin such as polyethylene waxes resulting from the polymerization of ethylene and waxes obtained by Fischer-Tropsch synthesis at melting point> 50 ° C, fatty acid esters and concrete glycerides at 50 ° C, silicone waxes such as alkyl, alkoxy and / or poly (di) methylsiloxane esters solid at 50 ° C.
• the composition of the invention contains little or no "mattifying" fillers and in particular less than 5% of mattifying filler. This is particularly the case when it is desired to obtain a shiny deposit on keratin materials such as the lips, the eyelashes and the hair. On the contrary, for a foundation, this type of filler can be used.
• a mattifying filler is generally a filler which absorbs sweat and / or sebum from the skin such as silicas, talcs, clays, kaolins, polyamide powders (Nylon®).
• composition according to the invention can be produced by known methods, generally used in the cosmetic field.
• the subject of the invention is also a cosmetic process for caring for, making up or treating keratin materials of human beings and in particular of the skin, facial lips and integuments of human beings, comprising the application to keratin materials of the composition, in particular cosmetic, as defined above.
• Another subject of the invention is the use of an ester comprising 10 to 40 carbon atoms, in a makeup composition comprising a) at least one liquid fatty phase structured by at least one semi-crystalline polymer with organic structure, the melting point is greater than or equal to 30 ° C, b) a coloring matter, the liquid fatty phase, the coloring matter, the ester and the polymer forming a physiologically acceptable medium.
• Another subject of the invention is the use of a sufficient quantity of an ester comprising 10 to 40 carbon atoms, in a composition containing a physiologically acceptable medium comprising a) at least one liquid fatty phase structured by at least one polymer semi-crystalline with an organic structure, the melting point of which is greater than or equal to 30 ° C, and b) a coloring matter, as an agent for imparting slipperiness on application and gloss to said composition.
• the subject of the invention is also the use of an ester comprising 10 to 40 carbon atoms in a cosmetic composition containing a physiologically acceptable medium comprising at least one liquid fatty phase structured by at least one semi-crystalline polymer with organic structure, to obtain a composition that is slippery on application and shiny.
• the mixture C 2 consisting of: 200 g of stearyl acrylate + 400 g of cyclohexane is introduced over 1 hour 30 minutes.
• the reaction is left to act for an additional 3 hours at 80 ° C., then all of the cyclohexane present in the reaction medium is distilled.
• the polymer is then obtained at 60% by weight of active material in the Parléam.
• Example 2 Copolymer with a Melting Point of 48 ° C
• Example 2 The same procedure is applied as in Example 1, except that a mixture of 10 g of N-Vinyl Pyrrolidone and 190 g of stearyl acrylate is used.
• the polymer obtained is 60% by weight of active material in Parleam, its weight average molecular weight is 43,000-53,000 and its T f is 48 ° C.
• Example 2 The same procedure is applied as in Example 1, except that behenyl acrylate is used in place of stearyl acrylate.
• the polymer obtained is 60% by weight of active material in Parléam. Its weight average molecular weight is 17000-27000 and its T f of 58 ° C.
• Example 4 Copolymer with a Melting Point of 58 ° C
• Example 2 The same procedure is applied as in Example 2, except that behenyl acrylate is used in place of stearyl acrylate.
• the polymer obtained is 60% by weight of active material in Parléam®. Its weight average molecular mass is 23500-33500 and its T f is 58 ° C.
