Polysaccharide / Hydrating Agent

Dextran

Dextran is a naturally derived polysaccharide composed of glucose units linked through α-C1-C6 chains, produced by bacterial fermentation using species such as Leuconostoc and Streptococcus. In cosmetics it primarily functions as a viscosity controller and binder, helping to thicken and stabilise formulations. It also demonstrates humectant-like water-retention properties, supports the delivery of co-applied active ingredients, and has been shown to stimulate cell growth and boost tissue regeneration.
