lactic acid Description:
PRODUCT DATA |
L-Lactic acid (90%)
(HPG) |
Description
L-Lactic acid 90% (HPG) is the natural L (+) lactic acid, which is produced by bio-fermentation from grain starch. It’s colorless, nearly odorless, syrupy liquid having a slight acid taste. It is hygroscopic, and all soluble in water, ethanol or ether, but insoluble in chloroform.
