Ethyl lactate, also known as lactic acid ethyl ester, is a monobasic ester formed from lactic acid and ethanol, commonly used as a solvent. This compound is considered biodegradable and can be used as a water-rinsable degreaser. Ethyl lactate is found naturally in small quantities in a wide variety of foods including wine, chicken, and various fruits. The odor of ethyl lactate is mild, buttery, creamy, with hints of fruit and coconut.

Due to its relatively low toxicity, ethyl lactate is used commonly in pharmaceutical preparations, food additives, and fragrances. Also used as solvent for nitrocellulose, cellulose acetate, and cellulose ethers.

Ethyl lactate hydrolyzes in the presence of water and acids or bases into lactic acid and ethanol.
