Problems solved by technology

[0007] Although these formulations do enable some matte-holding properties in cosmetic compositions, they can be accompanied by unpleasant sensations and discomfort, either during product application (difficulty spreading, sticky effect, greasy feel, etc.) or throughout the day. Medium (tension, mask effect, etc.)

Embodiment 1

[0350] The liquid foundations of Example 1 and Example 2 can show that the dendritic silicone acrylates of the present invention provide better matte finish retention than silicone resins.

[0351]

[0352]

[0353] Process Example 1

[0354] Weigh the components of phase A1 in the main beaker, then stir the components by a Moritz stirrer (1000 rpm) while keeping at room temperature.

[0355] Next, phase A2 was added at room temperature with stirring using a Moritz stirrer (1000 rpm) until homogeneous.

[0356] Phase A3 was independently prepared by grinding the mixture of pigment and cyclohexasiloxane three times in a three-roll mill.

[0357] This phase A3 is then added with continuous stirring along with phases A4 and A5.

[0358] Prepare aqueous phase B separately by weighing butanediol and magnesium sulfate in a beaker, adding water preheated to 95°C.

[0359] Stir the aqueous phase using a magnetic bar until homogeneous.

[0360] Prepare the emulsion at room te...

Embodiment 2

[0364] Weigh the components of phase A1 in the main beaker, then stir the components by a Moritz stirrer (1000 rpm) while keeping at room temperature.

[0365] Phase A2 was previously prepared by dispersing the silicone resin in isododecane while stirring using a Rayneri stirrer (approximately 100 rpm) equipped with a deflocculating paddle.

[0366] Phase A2 was then added at room temperature with stirring using a Moritz stirrer (1000 rpm) until homogeneous.

[0367] Phase A3 was independently prepared by grinding the mixture of pigment and cyclohexasiloxane three times in a three-roll mill.

[0368] This phase A3 is then added with continuous stirring along with phases A4 and A5.

[0369] Aqueous phase B was also prepared separately by weighing butanediol and magnesium sulfate in a beaker, adding water preheated to 95°C.

[0370] Stir the aqueous phase using a magnetic bar until homogeneous.

[0371] Prepare the emulsion at room temperature: Inject the aqueous phase B into...

Abstract

The present invention concerns a composition comprising a physiologically acceptable medium containing perlite and at least one vinyl polymer bearing at least one carbosiloxane dendrimer-based unit.

Description

technical field [0001] The present invention relates to compositions for caring and / or making up the skin. More specifically, the present invention relates to compositions for imparting a matte effect to the skin and improving the maintenance of this matte effect over time. Background technique [0002] Cosmetic compositions, such as foundations, are commonly used to impart color and aesthetics to the skin, especially the face. These cosmetic products generally contain oils, pigments, fillers and optionally additives such as cosmetic or dermatological actives. [0003] The use of fillers to obtain a matte effect is known to those skilled in the art. These fillers are usually selected for their sebum absorbing properties and / or for their light scattering capabilities. However, these fillers generally have poor adhesion to the skin, especially in the presence of sebum. [0004] Therefore, film-forming polymers can be used to improve the adhesion of these fillers and increa...
