Sodium Levulinate
What is Sodium Levulinate?
Sodium Levulinate is the sodium salt of levulinic acid, an organic compound derived from renewable biomass like sugarcane or agricultural waste through acid hydrolysis. This short-chain carboxylic acid salt appears as a white powder, soluble in water, making it ideal for water-based formulations. In cosmetics, it functions mainly as a skin conditioning agent by forming a protective film on the skin surface, aiding moisture retention and improving texture. It also provides mild antimicrobial support, helping preserve product integrity in natural formulations without synthetic alternatives. Commonly found in creams, lotions, and serums at low levels, it contributes to a lightweight feel and stability, appealing to clean beauty trends due to its biodegradable and eco-friendly profile.
