POLYSILICONE-1 CROSSPOLYMER.

Valuable CAS 1004791-75-6 / SKIN CONDITIONING, VISCOSITY CONTROLLING

Polysilicone-1 Crosspolymer is a silicone elastomer primarily utilized for its exceptional skin conditioning and texture-enhancing properties. It forms a smooth, protective film, offers a matte finish through oil absorption, and subtly blurs the appearance of fine lines, contributing to a visibly refined and softer skin texture.

Science

Mechanism of Action

This ingredient functions by creating a non-occlusive, silky film on the skin's surface, enhancing hydration and suppleness. As a proficient viscosity controlling agent, it precisely adjusts product consistency. Its porous structure enables significant oil absorption, delivering a desirable matte effect, while its light-diffusing capabilities create a soft-focus visual. Additionally, it can temporarily mitigate the appearance of superficial fine lines and wrinkles, promoting a smoother skin topography.

Stability

Supplied as a hybrid silicone powder, Polysilicone-1 Crosspolymer disperses effectively into pigments and other components, leading to highly stable cosmetic formulations. It excels at stabilizing lipophilic active ingredients such as UV filters, anti-aging compounds, and fragrances. Furthermore, it increases the viscosity of non-aqueous systems and contributes to controlled release characteristics.

Synergies

  • Lipophilic active ingredients (e.g., UV filters, anti-aging compounds, perfumes) for enhanced stabilization and controlled release.
