What Is Biosaccharide Gum-1?
Biosaccharide gum-1 is a complex sugar (polysaccharide) typically obtained via bacterial fermentation. It’s used in cosmetics for film-forming and texture-enhancing properties but also has humectant (water-binding) and soothing properties on skin.
Along with improving texture, biosaccharide gum-1 can help reduce a sticky, tacky finish, replacing it with a smoother feel. It’s compatible within a broad pH range and “plays well” with countless ingredients, making it a versatile tool in a cosmetic chemist’s bag of tricks.
The usage levels of biosaccharide gum-1 in cosmetics ranges from 0.5–8% when supplied as a gel (although 6% was the maximum reported used in this ingredient’s safety assessment). When supplied in concentrated powder form, lower amounts of 0.1–1% suffice. This ingredient is considered safe for use in cosmetics.
