Description

Features and Benefits

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is a safer and more sustainable alternative to ethyl acetate and acetone. It is an ester of natural L-lactic acid, which is produced by fermentation of sugar and thus aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks".
