Science

Mechanism of Action

POLYPROPANEDIOL-2 provides multiple benefits by improving skin condition and optimizing formulation stability. On the skin, it acts as a powerful humectant, drawing and retaining moisture to boost hydration and moisturization levels. It effectively functions as a solvent, facilitating the dissolution and dispersion of other key ingredients such as salicylic acid, ferulic acid, allantoin, and ascorbic acid, thereby enhancing their delivery. Furthermore, it acts as a penetration enhancer, optimizing the absorption of active compounds. Within formulations, POLYPROPANEDIOL-2 stabilizes emulsions, controls product viscosity, and serves as an emollient to soften skin. It also functions as a plasticizer for improved texture, a surfactant for cleansing and emulsification, and can boost the efficacy of preservatives.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) expert panel has concluded that Propanediol, which POLYPROPANEDIOL-2 is derived from, is safe for use in cosmetics. While it is categorized as a skin irritant, the Environmental Working Group (EWG) indicates that associated health risks in cosmetics are low. Approval for cosmetic use, often in restricted amounts, is established in the United States, Canada, and Europe. Studies suggest a very low percentage of individuals experience irritation when it is absorbed through the skin from topical applications.
