Problems solved by technology

However, these compositions are not entirely satisfactory and generally do not provide a matte finish that is consistent over time and must therefore be reapplied on a regular basis to achieve the desired effect, especially if the exposure time exceeds 4 hours. hours later

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:

[0117] -Sold by Penreco under the trade name Versagel M5950

[0118] Isododecane of Kraton (triblock and free radical) gel 4.48g

[0119] - Isododecane 1.97g

[0120] - Polydimethylsiloxane containing a-omega ethylene oxide propylene oxide groups

[0121] (DP: 100-58 / 42) and the trade name sold by Goldschmidt

[0122] Cyclopentasiloxane (85 / 15) mixture of "Abil EM 97" 0.90 g

[0123] - Cyclopentadimethicone 4.00g

[0124] -The trade name sold by Atochem Company is

[0125] Orgasol 2002 Extra D Nylon 12 Powder by Nat.Cos. 3.00g

[0126] -The product sold by Sumitomo is called Flobeads  EA-209

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...
