Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed polyurethane ingredients, including this copolymer, safe for topical cosmetic use when properly formulated to be non-sensitizing. It is crucial to differentiate the safety profile of the copolymer from its monomer, 1,4-Butanediol, for which topical safety data is insufficient, and which poses a Class I health hazard if ingested orally due to its conversion to gamma-hydroxybutyrate (GHB).
