Description
Ethyl lactate is a clear, colorless liquid with a mild, pleasant odor. It is the ethyl ester of lactic acid and is known for its high solvency and low toxicity. As a biodegradable solvent, it offers excellent performance in both water- and solvent-based systems.
It dissolves many resins, greases, and oils. In addition, it serves as a green alternative to traditional solvents like acetone or toluene. Due to its favorable environmental profile, ethyl lactate is widely used in paints, coatings, agrochemicals, and electronics.
Formulators prefer it in applications that demand strong solvency, low volatility, and low environmental impact.
