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".

A new approach using aqueous ethyl lactate-modified [S,S]-ethylenediaminedisuccinic acid (EDDS) washing solutions was examined in the laboratory for the simultaneous removal of phenanthrene, pyrene, and Cu from contaminated soils. Ethyl lactate demonstrated greater solubilization efficiency for phenanthrene and pyrene than

Chloroethenes like tetrachloroethene (PCE) are the most prevalent groundwater contaminants in the USA. Their presence as nonaqueous phase liquids (NAPLs) makes remediation difficult. Among options for NAPL cleanup, co-solvent injection has demonstrated success. However, the process has the potential to
