Science

Mechanism of Action

DIMETHOXYDIPHENYLSILANE/TRIETHOXYCAPRYLYLSILANE CROSSPOLYMER is a precisely engineered synthetic compound, created by the crosslinking of dimethoxydiphenylsilane and triethoxycaprylylsilane polymers. Upon application, its distinct molecular structure allows it to create a cohesive, enduring film on the skin. This film, alongside the compound's natural affinity for water molecules, imparts a notably smooth and silky finish to the skin. Additionally, it serves to refine the texture of cosmetic formulations and is effectively utilized as a coating agent for zinc oxide nanoparticles, stabilizing and dispersing them.

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that this ingredient, consistent with other dimethicone crosspolymers, is safe for use in cosmetic applications at current practices of use and concentration. Triethoxycaprylylsilane, a foundational component of this crosspolymer, also holds a CIR safety designation. The Scientific Committee on Consumer Safety (SCCS) specifically determined that zinc oxide nanoparticles coated with this cross-polymer are safe for dermal application, functioning as a UV-filter, at concentrations up to 25%. EWG Skin Deep indicates 'LOW' concerns across categories including cancer, allergies, immunotoxicity, and developmental/reproductive toxicity, though noting 'Limited Data Availability'. SkinSAFE certifies it free of common irritants and allergens, classifying it as safe for sensitive areas like lips and eyelids, and for use by teens and babies.
