Embodiment 1

[0122] Example 1: Preparation of Film-Forming Polymer Dispersion

[0123] According to the method in Example 7 of document EP-A-749747, a dispersion of non-crosslinked copolymer of methyl acrylate and acrylic acid was prepared in isododecane, the ratio of methyl acrylate and acrylic acid being 85 / 15. A poly(methyl acrylate / acrylic acid) particle dispersion in isododecane was surface stabilized with a polystyrene / co(ethylene-propylene) diblock copolymer sold under the name Kraton G1701 (Shell), which The dispersion was obtained with a solids weight percent of 22.6%, an average particle size of 175 nm (polydispersity: 0.05) and a Tg of 20°C. This copolymer can form a film at room temperature (25°C).

Embodiment 2

[0125] A foundation in the form of a water-in-oil emulsion was prepared having the following composition:

[0126] oil phase :

[0131] - Polydimethylsiloxanes containing alpha-omega ethylene oxide propylene oxide groups

[0132] (DP: 100-58 / 42) and the trade name sold by Goldschmidt

[0133] Cyclopentasiloxane (85 / 15) mixture of "Abil EM 97" 0.90 g

[0134] - Cyclopentadimethicone 4.00g

[0135] -The trade name sold by Atochem Company is

[0136] Orgasol 2002 Extra D Nylon 12 Powder by Nat.Cos. 3.00g

[0137] - Hydrated magnesium aluminum silicate sold under the trade name Neusilin UFL2 by Fuji Chemical Company 4.00 g

[0138] - distearyl dirare earth element (monium) hectorite, cyclopentadiene and siloxane

Abstract

The present invention relates to a cosmetic composition for caring for and / or making up the skin and / or the lips, comprising at least one liquid fatty phase, the said fatty phase containing at least one film-forming polymer and silicate particles.

Description

technical field [0001] The present invention relates to a cosmetic composition for making up and / or caring for the skin, especially the face. Background technique [0002] Such compositions are in particular in the form of stick or disc die-cast products, such as lipsticks or lip balms, die-cast foundations, concealer products, eye shadows or make-up blush, and more or less liquid ointment or cream products, such as liquid foundations Or a lipstick, an eyeliner, a sunscreen composition or a skin coloring composition or alternatively a body makeup composition. [0003] Cosmetic or care products for human skin or lips, such as foundations or lipsticks, usually comprising a fatty phase in the form of oils and / or waxes, pigments and / or fillers and optionally additives such as cosmetic active agents or dermatologically active agent-based. [0004] More particularly, the compositions contemplated by the invention can be used to form cosmetics, for example for the face, which pro...
