Regulatory Status

EU EU Status permitted
US US Status permitted
US Notes CIR 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.
