Polydextrose is a polymer composed of glucose, sorbitol and citric or phosphoric acids. Considered a polysaccharide (complex sugar) and prebiotic, it’s used in cosmetics to enhance texture, stabilize formulas, add bulk, and improve the solubility of key ingredients such as salicylic acid.
Polydextrose is also approved for use in food in over 60 countries, where it serves as a source of non-digestible prebiotic fiber and can also improve the flavor and mouth feel of low- and non-fat foods. Its neutral flavor makes it versatile in everything from baked goods to fiber-enriched beverages, including infant formula. Its safety as used in food was reevaluated in 2021 and the original safety conclusion was reconfirmed. As such, it is also considered safe for topical use via cosmetics without restrictions.
