Polymeric C8 Silane (AS)-Treated Pigments; INCI name: Polycaprylylsilsesquioxane

AS-treated pigments and fillers are coated with an alkyl-functional silsesquioxane which provides a hydrophobic coating that increases the ease of particle dispersion in natural and synthetic fluids and helps to stabilize particles in emulsion systems. The AS treatment is polymer based to allow for registration as a polymeric material.

AS Treatment Benefits:

  • Polymeric C8 (Caprylyl) treatment
  • Globally approved
  • Hydrophobic
  • Improves wear on skin
  • Decreases oil absorption

Recommended Uses:

  • BB creams
  • Foundations
  • Pressed powders
