Butyl Acetate

What is Butyl Acetate?

Butyl Acetate is a clear, volatile liquid ester derived from butyric acid and butanol through esterification, commonly produced synthetically for industrial use. In cosmetics, it belongs to the category of organic solvents and fragrance compounds, primarily featured in nail care products such as polishes and removers. It functions by dissolving resins, pigments, and polymers, enabling smooth application and quick drying through rapid evaporation. Additionally, it imparts a mild fruity odor, helping to enhance or mask scents in formulations. Its low boiling point makes it ideal for fast-evaporating systems, contributing to product texture and performance without leaving residue.
