Despription

A micro-fine spherical cross-linked siloxane particle which has slightly broader particle size distribution.

Provides an exceptional feel to skin when incorporated into a variety of cosmetic formulations.

Its performance result in excellent lubricity of skin lotions and lipsticks, reduction of powder agglomeration in pressed powders, good spreadability in skin creams and soft focus effects.

Soft focus results in reduction in the appearance of fine lines and wrinkles through the use of facial lotions, anti-ageing and decorative color cosmetics.

Polymethylsilsesquioxane is a high-purity, spherical silicone resin powder. Unlike standard silicone fluids, these micro-fine spherical particles provide a unique combination of water repellency, heat resistance, and a lubricious, "velvet-like" skin feel. Due to its refractive index being close to that of skin, it offers a dramatic "soft-focus" effect, physically blurring the appearance of fine lines and wrinkles while providing excellent oil absorption and anti-caking properties.
