Embodiment 1

[0111] Example 1: Preparation of Lipid Dispersible Film-Forming Polymer Dispersions

[0112] 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

[0114] A foundation in the form of a water-in-oil emulsion was prepared having the following composition:

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 lipodispersible film-forming polymer and polyethylene particles with a number-average size of less than or equal to 50 mum.

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...
