Science
Mechanism of Action
As a skin conditioning agent, PPG-34 contributes to maintaining the skin's optimal state by forming an emollient film that helps reduce transepidermal water loss. Its solvent properties facilitate the dissolution of lipophilic active ingredients, ensuring uniform distribution and potential for enhanced dermal delivery.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that polypropylene glycols with a degree of polymerization of 3 or greater, including PPG-34, are safe for use in cosmetics when formulated to be non-irritating. The European Union's CosIng database does not impose restrictions on its use. Furthermore, the FDA considers propylene glycol, a related compound, as Generally Recognized As Safe (GRAS) for direct food addition and approves its use in topical pharmaceuticals at concentrations up to 98%.
