Polyglucuronic Acid


Film-Forming Agent

Polyglucuronic Acid description

Polyglucuronic acid is a polysaccharide that occurs in many natural gums. It serves as a film-forming agent in cosmetics and has humectant properties that smooth skin and prevent dehydration. Usage levels of polyglucuronic acid in cosmetics range from 1–3%, the latter being if it’s part of a blend with other hydrators. Although it may be plant-derived, it is often made via bacterial fermentation since this process offers greater yield and quality control.
