Safety Profile
The Cosmetic Ingredient Review (CIR) assessed Propylene Glycol Esters (PGS), the chemical class encompassing Ethyl PG-Acetal Levulinate, determining it to be safe as used. Findings included no significant skin irritation at concentrations up to 55% and no sensitization at 1.5%-2.5% for this broader class. While the EPA classifies it as a 'low concern' chemical, GHS classification does indicate a potential for serious eye irritation (H319).
