Application

Ethyl lactate, an organic ester derived from lactic acid, serves as a versatile and eco-friendly solvent obtained from the processing of corn. Its biodegradability and non-toxic nature make it particularly attractive for various applications, including the paints and coatings industry. As a high-performance solvent, ethyl lactate effectively dissolves substances like nitrocellulose and cellulose acetate, and it is used in lacquers, enamels, and varnishes. Furthermore, it is notable for its role as a green alternative to traditional solvents such as toluene, acetone, and xylene, thereby improving workplace safety by reducing hazardous chemical exposure. In addition to industrial uses, ethyl lactate is employed as a flavoring agent in food and beverages, as well as in cosmetic formulations like soaps and lotions. Its high solvency power, coupled with a high boiling point and low vapor pressure, underlines its practicality in diverse settings, from removing salts in electronics to stripping paint and graffiti.
