• Description: Butyl lactate is a kind of lactate derived ester. As a kind of alpha-hydroxy acid ester, its applications in cosmetic, food and pharmaceutical formulations have significantly increased due to their hygroscopic, emulsifying and exfoliating properties. It is used as a food additive because of its flavoring effect. In industry, it can be used as solvent and chemical feedstock. As a bio-based solvent, it can be used as extractant for removing 1-butanol from the aqueous fermentation broths. It can be generally manufactured through the action of lipase from various origins.
• Uses: n-Butyl lactate is used as a food and feed additive. Butyl lactate has been used:in the preparation of solid lipid nanoparticles by a solvent emulsification–diffusion techniquein the synthesis of nanoparticles of griseofulvin from water dilutable microemulsions by the solvent diffusion techniqueas cosurfactant on the preparation of microemulsions with anionic surfactant Solvent for nitrocellulose, ethyl cellulose, oils, dyes, natural gums, many synthetic polymers, lac- quers, varnishes, inks, stencil pastes, antiskin- ning agent, chemical (intermediate), perfumes, dry- cleaning fluids, adhesives.
