Biosaccharide Gum-1 is a high-molecular-weight polysaccharide produced via biotechnological fermentation of plant-derived sugars, typically involving bacterial strains such as Sphingomonas. Structurally, it is a branched anionic heteropolysaccharide composed primarily of fucose, galactose, and glucose units. In skincare formulations, this ingredient is valued for its exceptional humectant capacity and film-forming behavior, which allow it to bind water efficiently while creating a breathable, protective layer on the skin surface. This film reduces transepidermal water loss (TEWL), enhances immediate skin comfort, and contributes to a smoother, more hydrated appearance. Its macromolecular nature also provides a subtle sensory refinement, improving slip and softness without occlusion.

Beyond hydration, it demonstrates soothing and anti-irritation properties, making it particularly suitable for formulations targeting sensitive, reactive, or environmentally stressed skin. In vitro and in vivo evaluations indicate that this polysaccharide can help modulate skin discomfort markers associated with dryness, shaving, or exposure to irritants. While its primary application is in skincare, this material also has relevance in hair and scalp care, where it functions as a lightweight conditioning and film-forming agent. On hair fibers, it can improve manageability, reduce surface roughness, and contribute to moisture retention on the scalp, especially in leave-on products designed for comfort rather than styling hold.
