Science

Mechanism of Action

Operating as an emollient, surfactant, and emulsifying agent, PEG-4 DIHEPTANOATE actively softens and soothes the skin while enhancing overall product elegance. It effectively blends oil and water components into stable emulsions, thereby improving formulation consistency and stability. Additionally, its roles as a coupling agent and wetting agent can facilitate the enhanced penetration of other active ingredients into the skin.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PEG diesters, including PEG-4 DIHEPTANOATE, are safe for cosmetic application when formulated to be nonirritating. Animal studies demonstrated slight to moderate erythema and edema in rabbit skin at 100% concentration, and mild irritation in guinea pigs at 50% and 100% concentrations. However, no irritation was observed at 5% or 25% concentrations in guinea pigs. The U.S. FDA has affirmed its safety for general or specific limited use in food. As an ethoxylated ingredient, there is a potential for trace contamination with ethylene oxide and 1,4-dioxane during its manufacturing process.
