Embodiment 1

[0390] Example 1: Polymer Dispersion

[0391] With the method of the embodiment 1 of EP-A-749746A, replace heptane with isododecane, prepare the uncrosslinked copolymerization of methyl acrylate and acrylic acid in the ratio of methyl acrylate and acrylic acid 95 / 5 in isododecane dispersion of matter. This produced poly(methyl acrylate / acrylic acid) particles surface stabilized in isododecane by a block polystyrene / co(ethylene-propylene) diblock copolymer (sold under the name Kraton G1701). Dispersion with a solids content of 25% by weight.

Embodiment 2

[0392] Example 2: Lipstick

[0393] polyethylene wax

[0394] (weight average molecular weight: 500) 10.5%

[0395] straight chain fatty alcohol

[0396] (Performacol 550 alcohol, produced by

[0397] New Phase Technologies) 2.5%

[0398] Dispersion of Example 1 68%

[0399] Sucrose Acetate Isobutyrate

[0400] (Eastman SAIB, sold by Eastman Chemical) 5%

[0401] Pigment paste 13.5%

[0402] Spice 0.5%

[0403]Put polyethylene wax, C30-C50 alcohol and pigment paste into a heating vessel, heat at 100°C, and stir with a magnetic force to form a homogeneous mixture. The composition of the dye paste was 70% pigment, 1% poly(12-hydroxystearic) stearate and 29% hydrogenated polyisobutylene.

[0404] The dispersion of Example 1 and sucrose acetate isobutyrate were then added while maintaining the temperature and stirring until the mixture was homogeneous. The composition is poured into the mold. The obtained rods were uniform in color and good in shape. They form a coatin...

Embodiment 3

[0405] Example 3: Lipstick as first composition

[0406] Polystyrene / poly(ethylene-propylene)

[0407] Kraton G-1650E

[0408] (sold by Kraton) 0.5%

[0409] Dispersion of Example 1 65%

[0410] polycaprolactone

[0411] (Capa 2125, produced by Solvay) 10%

[0412] Sucrose Acetate Isobutyrate

[0413] (Eastman SAIB, sold by Eastman Chemical) 10%

[0414] Pigment paste 13.5%

[0415] Appropriate amount of spices

[0416] Appropriate amount of preservatives

[0417] Melt polycaprolactone at 100°C, then add the pigment paste while stirring, the composition of the pigment paste is the same as

[0418] The same as that of embodiment 2.

[0419] The other ingredients are then added until a homogeneous mixture is obtained. The mixture is then cooled to ambient temperature and packaged in cans.

Abstract

A cosmetic makeup product comprising at least two compositions, the first composition comprising a physiologically acceptable medium and the second composition comprising a mixture of at least one high molecular weight polymer having a weight-average molecular mass of greater than or equal to 200,000 g/mol and at least one low molecular weight non-volatile liquid silicone compound having a weight-average molecular mass of less than 200,000 g/mol, wherein the at least one high molecular weight polymer and the at least one low molecular weight non-volatile liquid silicone compound are present in a proportion such that the dynamic viscosity of the mixture at 25 DEG C., measured with a Mettler RM 180 rotational viscometer, ranges from 0.1 to 120 Pa.s; a makeup method and a makeup kit comprising the cosmetic makeup product. The cosmetic makeup product may, for example, be a lipstick.

Description

technical field [0001] The present invention relates to a new cosmetic cosmetic product comprising at least two compositions which can be applied in succession to the skin of the face and the human body, the upper and lower eyelids of humans, the lips and derivatives of the epidermis, such as nails, Eyebrows, eyelashes or hair, and also involves double-layer makeup methods for the face and body. [0002] One of said compositions may be a loose or compact powder, foundation, blusher or eye shadow, concealer, lip balm, lip gloss, lip balm Or eye pencil (pencil), mascara, eyeliner (eyeliner), nail polish, or body makeup or skin coloring products (skin coloring product). [0003] The product provides good coverage and staying power, a glossy, odorless, comfortable makeup that is non-transferring and easy to apply. [0004] The present invention more particularly relates to compositions for the care or grooming of keratinous substances such as the skin of the face and the human b...
