Embodiment A to Embodiment O

[0266] Example A to Example O: Effect of Surfactant Properties

[0267] Examples A to O show the effect of the structure of the surfactant on the dispersibility of an aqueous suspension of a silicone elastomer (BY29-119 from Dow Corning) in an oil phase.

[0268]

[0269] step

[0270] The ingredients of phase A were weighed out in a main beaker and then stirred (1600 rpm) using a Moritz stirrer while keeping at room temperature.

[0271] Then, phase B was added while stirring with a Moritz mixer (3500 rpm) until homogeneous.

[0272] result

[0273]

[0274]

Embodiment 1

[0275] Example 1: Water-in-Oil (W / O) Foundation

[0276] This example illustrates the first group of silicone surfactants of the present invention.

[0277] Therefore PEG-9 polydimethylsiloxyethyl dimethicone (KF6028 from Shin-Etsu), which can disperse an aqueous suspension of silicone elastomer (BY29-119 from DowCorning) in in the external oil phase of the emulsion.

[0278]

[0279] Step Example 1

[0280] 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.

[0281] Phase A2 was prepared separately by milling the mixture of pigment and dodecamethylpentasiloxane three times in a three-roll mill.

[0282] Next, add phase A2 at room temperature and stir with a Moritz stirrer (375 rpm) until homogeneous.

[0283] Phase A3 was then added and stirring continued (500 rpm) using a Moritz stirrer.

[0284] Aqueous phase B was also prepared separately by weighing out glycerin and ...

Embodiment 2

[0293] Example 2: Water-in-Oil (W / O) Foundation

[0294] This example illustrates the second group of silicone surfactants of the present invention.

[0295] Bis-PEG / PPG-14 / 14 dimethicone (Abil EM97 from Evonik Goldschmidt) was therefore used, which allows dispersion of an aqueous suspension of a silicone elastomer (BY29-119 from Dow Corning) in the outer oil phase of the emulsion middle.

[0296]

[0297]

[0298] step

[0299] With embodiment 1.

[0300] sensory evaluation

[0301] In the half-face makeup test, a group of five women from the lab, aged 25 to 50, were asked to apply the foundation.

[0302] From this evaluation it appears that the foundation produces an even, consistent makeup result and can smooth the pores.

Abstract

The invention relates to a cosmetic composition comprising at least an oily phase, the said oily phase comprising at least: (i) a silicone elastomer present in aqueous droplets which are dispersed in said oily phase, (ii) at least one particular surfactant chosen from: -a) silicone surfactants having a chemical structure comprising silicone side chains and hydrophilic side chains, of which the general formula (I) is: (I) -b) silicone surfactants having a chemical structure comprising hydrophilic chains at both ends ([alpha]-[omega]substitution) of the main chain, of general formula (II) below: (II) -c) hydrocarbon-based surfactants resulting from the esterification of a mixture of polyglycerol with (i) a polyhydroxystearic acid, with 2 to 5 polyglycerol units, (ii) linear or branched aliphatic dicarboxylic acids containing 4 to 14 carbon atoms, and (iii) saturated or unsaturated, linear or branched fatty acids containing from 16 to 20 carbon atoms.

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, have a smoothing effect on bumps, especially pores, wrinkles and fine lines. [0002] More specifically, the present invention relates to a cosmetic composition comprising an oily phase containing at least (i) a silicone elastomer present in water droplets dispersed in said oily phase, and (ii) at least one a specific surfactant. 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, sagging and loss of elasticity, as well as dilated visible pores. [0004] Especially for people with dilated pores, regardless of their origin: ethnicity (eg Asian population, Caucasian popul...
