Science
Mechanism of Action
This polyquaternary organosilicone is highly substantive, meaning it adheres effectively to the skin. It functions as a surfactant by reducing surface tension and creating a vapor-permeable protective film. This film enhances the skin's moisture balance, provides emollient benefits, and improves product glide for a distinctly smooth skin feel.

SILICONE QUATERNIUM-17 is stable but susceptible to oxidation. It is a low viscosity, pourable liquid, fully soluble in water, and cold processable. It can be incorporated into formulations at the final stage with gentle mixing.
Safety
Safety Profile
While the Cosmetic Ingredient Review (CIR) has not specifically reviewed SILICONE QUATERNIUM-17, silicones generally exhibit low comedogenicity and are well-tolerated on the skin. This ingredient is listed as 'Irritant Free' on SkinSAFE. However, in its concentrated liquid form, it may induce irritation to the skin, eyes, and respiratory system. It is not currently present on EWG's Skin Deep Restricted or Unacceptable Lists, supporting its general safety profile in cosmetic applications.
