Embodiment 1 and Embodiment 2

[0271] Example 1 and Example 2: Influence of the presence of the organopolysiloxane elastomer according to the invention (in introduced as an aqueous suspension)

[0272] A comparison of the fluid foundations of Example 1 and Example 2 shows that the presence of the organopolysiloxane elastomer delivered in the form of an aqueous suspension according to the invention makes it possible to obtain better smoothing properties.

[0273]

Embodiment 1

[0274] Step embodiment 1 (the present invention)

[0275] The ingredients of phase A1 were weighed out in a main beaker and then stirred (375 rpm) with a Moritz stirrer while keeping at room temperature.

[0276] Phase A2 was prepared separately by milling the mixture of pigment and dodecamethylpentasiloxane three times in a three-roll mill.

[0277] Next, add phase A2 at room temperature and stir with a Moritz stirrer (375 rpm) until homogeneous.

[0278] Phase A3 was then added and stirring continued (500 rpm) using a Moritz stirrer.

[0279] Aqueous phase B was also prepared separately by weighing out glycerin and preservatives in a beaker, then by adding water preheated to 95°C.

[0280] Stir the aqueous phase with a magnetic bar until homogeneous.

[0281] Prepare the emulsion at room temperature: pour the aqueous phase B into the fatty phase while gradually increasing the stirring speed (Moritz stirrer) up to 1,000 rpm. Stirring was continued for 10 minutes.

Embodiment 2

[0285] Step embodiment 2 (comparison)

[0286] In this example, the procedure was the same as that of Example 1, except that phase C was not present.

[0287] sensory evaluation

[0288] A group of 5 women aged 25 to 50 were asked to use the two foundations in the Half Face Makeup Test.

[0289] From this evaluation it appears that the foundation of Example 1 (invention) produces a more even, consistent and softer makeup result.

[0290] The foundation of Example 1 (invention) smoothed the pores, which was not observed by the foundation of Example 2 (comparative).

[0291] In the final analysis, women in this group appreciated the foundation of Example 1 (invention) more.

Abstract

The present invention relates to a cosmetic composition comprising, in a physiologically acceptable medium, an emulsion containing at least an aqueous phase and an oily phase, the said oily phase comprising at least: (i) a compound consisting of up to 99.9% by weight of silicone elastomer(s) and from 0.1% to 10% by weight of surfactant(s), said surfactant(s) being chosen from polyoxyethers of C10-C18 fatty alcohols; (ii) a silicone elastomer powder coated with a silicone resin, and (iii) a filler which contains a polymer comprising at least the alkyl(meth)acrylate monomer, the silicone elastomer of compound (i) being different from the powder (ii).

Description

technical field [0001] The present invention relates to the field of care and / or cosmetic compositions for the skin. More specifically, the present invention relates to compositions that, after application to the skin, produce a smoothing effect on bumps, especially pores. [0002] More specifically, the present invention relates to a cosmetic composition comprising at least (i) consisting of up to 99.9% by weight of a silicone elastomer and 0.1% to 10% by weight of 10 -C 18 A mixture of surfactants consisting of polyoxyethers of fatty alcohols, (ii) silicone elastomer powder coated with silicone resin, and (iii) selected from polyalkyl (meth)acrylate ), the silicone elastomer of the mixture (i) is different from the powder (ii). Background technique [0003] Men and women, regardless of their age, care about the appearance of their skin, especially facial skin. Facial skin can reveal the presence of wrinkles and fine lines, blemishes, hyperpigmentation, dark circles, sa...
