Silica Silylate is a siloxane polymer. Siloxanes are chemical compounds built around Silicium atom (Si), with empirical formula R2SiO, R could be organic. Siloxanes are made of chains alternating Silicium and Oxygen atoms (-Si-O-Si-O-Si-O-Si-). Siloxane name comes from Silicium, Oxygen and Alkane.

Silica Silylate is a non-water soluble powder. Dow Corning supplies it under the tradename VM 2270 Aerogel Fine Particles and says it is a highly efficient thickener, sebum absorber and soft focus agent (impacts the appearance of fine lines and wrinkles). It can be used as a thickening agent for organic oils. Its benefits in cosmetic formulas are summarized below :

  • Superior oil and sebum absorption
  • Highly efficient viscosity enhancement (thickening) of oil phase
  • Capable of absorbing polar and non-polar oils
  • Fragrance delivery and retention
  • Impacts the appearance of fine lines and wrinkles
  • Allows for cold processing

It is also supplied by Wacker under the tradename HDK H2000.
