Science
Mechanism of Action
This ingredient operates as a non-volatile, non-migrating silicone film former, establishing a continuous layer on the skin, hair, or nails. Its high refractive index effectively delivers a noticeable high-shine finish, particularly on lips and hair. The silicone resin structure provides excellent film-forming capabilities, and on the skin, it acts as a conditioning agent, reducing flakiness and restoring suppleness to dry or damaged areas. It also enhances product spreadability and contributes a silky, smooth tactile experience.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed Phenyl-Substituted Methicones, including Phenylpropyldimethylsiloxysilicate, safe for cosmetic use within current practices and concentrations. However, data is insufficient to establish safety for products that may be incidentally inhaled. Due to its large molecular weight, significant absorption into the skin is considered unlikely.
