Description and Uses
Glucono delta-lactone (C6H10O6), molecular weight 178.14, is an inner ester of gluconic acid. Commonly named gluconolactone, other synonyms include D-gluconic acid delta-lactone, D-glucono- 1, 5-lactone, and D-delta-gluconolactone. Some of its earliest uses as a food ingredient were as a flavoring (e.g., sherbets) and to reduce fat absorption in doughnuts and cones. Glucono deltalactone tastes sweet initially and has a slightly acid-aftertaste.
Geogard(R)Ultra is a synergistic blend of gluconolactone and sodium benzoate. This blend provides broad spectrum protection against product spoilage in a variety of personal care formulations. Product Data Sheet
