Science
Mechanism of Action
This ingredient functions by leveraging the distinct properties of its two primary components. The dimethicone/vinyl dimethicone crosspolymer creates a flexible, breathable film on the skin's surface, imparting a silky, powdery finish. This silicone matrix is adept at absorbing excess oil and sebum, refining product texture, and acting as a viscosity modifier and emulsion stabilizer. Concurrently, the oleyl erucate component, a fatty ester, provides potent emollient properties, effectively trapping moisture to prevent dryness and leaving the skin feeling smooth without any greasy residue. It mimics natural skin lipids, similar to jojoba oil, contributing to skin conditioning.

Stability
The dimethicone/vinyl dimethicone crosspolymer component contributes to enhanced formulation stability. Oleyl erucate demonstrates good stability at room temperature. While a specific optimal pH range for the combined ingredient is not explicitly stated, related silicone crosspolymers typically exhibit stability around pH 6-7.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed dimethicone crosspolymer ingredients, including this complex, safe for cosmetic applications. This safety profile is attributed to their large molecular size, which effectively prevents skin penetration and minimizes systemic absorption. They are considered non-irritating and non-sensitizing, even when used in concentrations exceeding 45%.
