What it is
Dimethicone silylate is a silicone-based resin in which a dimethicone backbone is modified with trimethylsiloxy or similar silyl units. In sunscreens it acts as a film former that helps the product spread into a smooth, uniform layer and improves the evenness and durability of the finish. It also contributes a soft, silky feel and can help suspend pigments in tinted formulas.
Safety & warnings
Silicone resins of this type are generally regarded as well tolerated, non-sensitizing, and low in irritation potential.
Origin & sourcing
Synthetic silicone resin derived from dimethicone (polydimethylsiloxane).
Questions everyone asks
What does dimethicone silylate do?
It acts as a silicone film former, helping the product spread smoothly and form an even, durable layer with a silky feel.
Is it the same as regular dimethicone?
It is related but is a silylated resin form, which gives it more film-forming and structuring character than fluid dimethicone.
