Biosaccharide Gum-1

Biosaccharide Gum-1 is a high–molecular weight film-forming polysaccharide used mainly as a humectant/skin-soothing agent, typically at low concentrations (~0.1–1%). Clinical and post-market experience suggests very low irritancy and it is generally well tolerated even in reactive skin, though rare stinging or contact reactions can occur in highly compromised barriers, so it is not scored as completely inert. Safety Notes: In commercial skincare, Biosaccharide Gum-1 is commonly used as a soothing/hydrating film-former at low levels (~0.05–0.3%) in serums, toners, and moisturizers where it supports slip and comfort without noticeable tack. Many leave-on products cluster around ~0.2–1.0%, while higher-strength consumer-available gels/masks and barrier-repair concentrates can reach ~2–5% to deliver a more substantive protective film and sensory cushioning (often with increased viscosity/tack). Rinse-off products typically sit toward the lower end because deposition time is limited, whereas leave-on formats are where the upper end is most often observed.
