Embodiment 1

[0317] Example 1: Polymer Dispersion

[0318] Adopt the method in the embodiment 1 of EP-A-749 746, replace the heptane wherein with isododecane, prepare methyl acrylate and the non-crosslinked copolymer that acrylic acid synthesizes with the ratio of 95 / 5 in isododecane Dispersion in alkanes. This resulted in a dispersion of poly(methyl acrylate / acrylic acid) particles in isododecane surface-stabilized by a block polystyrene / co(ethylene-propylene) diblock copolymer sold as Krraton G1701. body with a solids content of 25% by weight.

Embodiment 2

[0319] Example 2: Lipstick

[0320] polyethylene wax

[0321] (weight average molecular weight: 500) 10.5%

[0322] straight chain fatty alcohol

[0323] (Performacol 550 alcohol, sold by New Phase Technologies) 2.5%

[0324]Dispersion in Example 1 68%

[0325] Sucrose Acetate Isobutyrate

[0326] (Eastman $AIB, sold by Eastman Chemical) 5%

[0327] Pigment paste 13.5%

[0328] Spice 0.5%

[0329] Pour polyethylene wax, C30-C50 alcohol and pigment paste into a heating vessel and heat to 100°C with magnetic stirring to obtain a homogeneous mixture. The pigment paste composition was 70% pigment, 1% polystearate (12-hydroxystearate) and 29% hydrogenated polyisobutylene.

[0330] Sucrose acetate isobutyrate and the dispersion of Example 1 were then added while maintaining the temperature and stirring. The composition was cast into a mold at 40°C, and the mold was cooled at -20°C for thirty minutes. The sticks are then unmoulded. The resulting sticks are uniform in color...

Embodiment 3

[0331] Example 3: Lipstick as First Composition

[0332] Polystyrene / poly(ethylene-propylene)

[0333] Kraton G-1650E (sold by Kraton) 0.5%

[0334] Dispersion of Example 1 65%

[0335] polycaprolactone

[0336] (Capa 2125, manufactured by Solvay) 10%

[0337] Sucrose Acetate Isobutyrate

[0338] (Eastman $AIB, sold by Eastman Chemical) 10%

[0339] Pigment paste 13.5%

[0340] Aromatic amount

[0341] Appropriate amount of preservatives

[0342] The polycaprolactone was melted at 100° C., and then the pigment paste with the same components as in Example 2 was added under stirring. Subsequently, the other components are added until a homogeneous mixture is formed. Subsequently, the mixture was cooled to ambient temperature and filled into small tanks.

Abstract

A cosmetic composition (A), comprising a liquid lipid phase containing dispersed polymer particles (I), additionally contains at least one ester (II) of molecular weight less than 5000 (preferably less than 900), derived from at least one 1-7C carboxylic acid and a polyol containing at least four hydroxy groups.

Description

technical field [0001] The invention relates to a composition, especially for use in the field of cosmetics, comprising polymer particles dispersed in a liquid fatty phase, said particles being preferably surface-stabilized by a stabilizer. The composition further comprises an ester of an acid and a polyol, especially a sucrose ester. [0002] The present invention more particularly relates to a composition for the care or repair of keratinous substances, such as the skin of the face and body, including the scalp, epidermal derivatives such as eyelashes, eyebrows, nails and hair, also including human skin. Lips and upper and lower eyelids. [0003] The compositions of the present invention provide a long-lasting cosmetic that does not transfer and / or is easy to apply. [0004] A non-staining or transfer-free composition is one which, when it comes into contact with objects (glass, clothing, cigarettes), does not form deposits, or at least partially, on its substrate on these...
