Science
Mechanism of Action
As a saturated linear alkane, Heneicosane functions as an emollient and film-former, depositing a non-occlusive layer on the skin surface to enhance the skin's natural barrier and minimize transepidermal water loss. Within formulations, it acts as a lubricant to improve product slipperiness and spreadability, and as a viscosity-controlling agent (thickener) to adjust texture. Its low volatility also contributes to overall product durability.

Safety
Safety Profile
Animal studies indicate Heneicosane has low toxicity and irritancy, with primary skin irritation tests in rabbits showing no significant adverse reactions. Specific safety assessments by major regulatory bodies such as CIR, SCCS, or FDA for cosmetic use are not currently available.
