INCI: ETHYL ACETATE
Ethyl Acetate (CAS 141-78-6) is a cosmetic cosmetic ingredient functioning as Solvent, volatile carrier, fast-evaporating solvent for nail polish. EU Regulation 1223/2009 status: permitted; GHS signal word DANGER. Industrial safety data is also available in the chemical safety database. Same-CAS public records also appear in industrial chemical safety and pharmaceutical data.
US NotesCIR assessed ethyl acetate as safe in cosmetics. FDA GRAS status as food additive (21 CFR 184.1245). OSHA nail salon VOC ventilation requirements apply. Characterized in 2025 nail formulation review as having a lower toxicity profile compared to aromatic solvents. Faster evaporation rate than butyl acetate, typically blended to control nail polish dry time and film quality.
