Abstract

The object of the invention is to provide cosmetic compositions comprising at least a specific silicone gel with phenyl groups. It is developped by NUSIL under the name CXG-1106 (INCI name: phenyl trimethicone & diphenyl dimethicone crosspolymer) or CXG-1108 (INCI name: propanediol dicaprylate & diphenyl dimethicone crosspolymer), depending on the solvent. Phenyl groups are particularly interesting to give shine and gloss for lips products and to allow the compatibility with phenylated oils and UV filters as well. This new gel is a powerfull compatibilizing agent, also used for its plasticizer and sensorial properties (good spreadability, no ball up, smooth, and slip, slight tack during and after rub-in), in all types of cosmetic compositions.

MAKE-UP AND SKIN CARE COMPOSITIONS CONTAINING A SPECIFIC SILICON GEL

The object of the invention is to provide cosmetic compositions comprising at least a specific silicone gel with phenyl groups. It is developped by NUSIL under the name CXG-1106 (INCI name: phenyl trimethicone & diphenyl dimethicone crosspolymer) or CXG-1108 (INCI name: propanediol dicaprylate & diphenyl dimethicone crosspolymer), depending on the solvent.

This reticulated silicone gel appears transparent and colorless. The viscosity is 250,000 to 350,000 cP for CXG-1106 and 200,000 to 400, 000 cP for CXG-1108.

Phenyl groups are particularly interesting to give shine and gloss for lips products and to allow the compatibility with phenylated oils and UV filters as well. This new gel is a powerfull compatibilizing agent, also used for its plasticizer and sensorial properties (good spreadability, no ball up, smooth, and slip, slight tack during and after rub-in), in all types of cosmetic compositions.

For example, they can be combined with another film-former polymer or a combination of film-former polymers to improve the long-lasting of the formulas. These film-former polymers can be silicone film-formers, non-silicone film-formers, or their mixtures. Among silicone film former polymers we can mention:

- silicone resins as for example MQ-resins, T-resins or MTQ resins, such as Trimethylsiloxysilicate sold under commercial name Belsil TMS 803 sold by Wacker Chemie AG, Trimethylsiloxysilicate & polypropylsilsesquioxane sold under commercial name MQ1640 Flake Resin by Dow Corning,

- silicone acrylates as for example Isododecane & acrylates / polytrimethylsiloxymethacrylate copolymer sold under commercial name Dow CorningĀ® FA4002 ID silicone acrylate by Dow Corning,

- silicone Pullulan film-formers such as Trimethylsiloxysilylcarbamoyl Pullulan sold under commercial name TSPL-30-ID-F by Shin-Etsu Chemical Co,

- silicone Pressure Sensitive Adhesive, such as Dimethicone & trimethylsiloxysilicate/dimethiconol crosspolymer sold under commercial name Dow CorningĀ® 7-4411 Cosmetic Fluid by Dow Corning,

- fluorated silicone resins such as Dimethicone & Trifluoropropyldimethyl/Trimethylsiloxysilicate sold under commercial name XS66-B8636 by Shin Etsu,

- silicone urethane film-former such as Bis-Hydroxypropyl Dimethicone /SMDI copolymer sold under commercial name Silmer UR 5050 by Siltech LLC,

Among non-silicone film former polymers we can mention:

- sucrose acetate isobutyrate sold under commercial name Sustane SAIB by Eastman Chemical Company.

Silicone film-formers are preferred.

They can be combined with pigments or matte pearl pigments to obtain shades adapted to the skin color. Usually pigments are in the external phase. When the pigments (iron oxides and titanium dioxide) are into the oily phase for anhydrous foundations or water/silicone foundations, they can be treated with hydrophobic treatments. For example, we can mention:


- Amino-acid Treated Pigm...
