Also known as
Dextran polymer Bacterial dextran Leuconostoc dextran Polydextrose
Compatibility
Works well with:
Hyaluronic Acid Glycerin Niacinamide Panthenol Allantoin Peptides
Dextran is broadly compatible with most water-phase cosmetic actives and humectants. It is stable across a wide pH range and does not typically interact adversely with common preservatives or electrolytes at typical use levels. High concentrations of strong oxidizing agents may degrade the polysaccharide backbone.
Formulation notes
Dextran is a high-molecular-weight polysaccharide produced by bacterial fermentation (typically Leuconostoc mesenteroides) that functions as a humectant, film-former, and mild thickener in aqueous cosmetic formulations. It creates a smooth, plumping film on the skin surface that supports moisture retention and a soft skin feel, making it popular in serums and moisturizers. It is considered well-tolerated and non-irritating, with no significant safety concerns at cosmetic use levels.
