Gluconolactone is a naturally occurring polyhydroxy acid (PHA) with metal chelating, moisturizing and antioxidant activity. Gluconolactone can be produced by enzymatic oxidation of D-glucose oxidation. Its ability in free radicals scavenging accounts for its antioxidant property. It is used in cosmetic product and as a coagulant in tofu processing.
Gluconolactone is a naturally-occurring food additive used as a sequestrant, an acidifier, or a curing, pickling, or leavening agent. It is a cyclic ester of D-gluconic acid. Pure gluconolactone is a white odorless crystalline powder.
Gluconolactone is a Calculi Dissolution Agent. The mechanism of action of gluconolactone is as an Irrigation.
