Hydroxypropylammonium Gluconate
What is Hydroxypropylammonium Gluconate?
Hydroxypropylammonium Gluconate is a synthetic ingredient derived from gluconic acid, produced by oxidizing glucose, and neutralized with hydroxypropylamine to form a water-soluble ammonium salt. It belongs to the category of chelating and buffering agents in cosmetics. In formulations, it functions by forming stable complexes with trace metal ions such as iron, copper, and calcium present in water or raw materials. This prevents metals from catalyzing oxidative reactions that could lead to product discoloration, rancidity, or emulsion breakdown. It also helps maintain optimal pH levels for product stability and skin compatibility, commonly appearing in cleansers, toners, serums, and moisturizers across rinse-off and leave-on categories.
Benefits
