BIOSACCHARIDE GUM-4

Last update on Dec 3, 2025

Biosaccharide Gum-4 is an extraordinary ingredient providing natural goodness for both skin and hair. It forms a breathable film that protects the skin against pollution and oxidative stress. This helps prevent signs of early skin aging, such as wrinkles and fine lines. The film also hydrates the surface and reduces water loss - making skin supple and hair soft. Biosaccharide Gum-4 is commonly found in anti-pollution serums, skin barrier creams, hydrating gels, setting sprays, and makeup primers. Being natural, it is ideal for clean beauty and vegan cosmetics. Biosaccharide Gum-4 has intrinsic water-binding properties that also improve the texture and spreadability of these products.

What is BIOSACCHARIDE GUM-4 used for?

Film forming - Biosaccharide Gum-4 forms a transparent, lightweight film on the skin that enhances the wear resistance of cosmetic products. Unlike synthetic film-forming ingredients, it does not interfere with the skin’s respiration. Its mild and breathable nature makes it suitable for daily wear in hydrating creams and hair protecting sprays.
Conditioning - Biosaccharide Gum-4 provides a smooth, hydrated feel on the skin. It leaves a silky, non-tacky film that helps improve softness and reduce rough texture. Additionally, due to its humectant properties, it draws and retains moisture on the surface of skin and hair.
Anti-pollution agent - Biosaccharide Gum-4 protects the skin against pollution and environmental aggressors. The film it forms on the skin and hair helps reduce the adhesion of fine particulate matter (PM2.5, PM10) and heavy metals. This minimizes pollution-induced dullness, dryness, and irritation.
Texture enhancing - Biosaccharide Gum-4 improves the texture and glide of formulations. It can help enhance the viscosity of aqueous products and provide a soft, velvety finish.

Origin

Biosaccharide Gum-4 is a natural polysaccharide made through a biotechnological fermentation process of sorbitol and autolytic yeast extract. During fermentation, the microorganisms metabolize the sugars and secrete a protective biofilm-like polysaccharide into the surrounding medium. Once the fermentation reaches the desired concentration, the mixture is filtered to remove cells and impurities.

Safety Profile

Biosaccharide Gum-4 is safe and well-tolerated in cosmetics within the recommended concentration range of 0.5% to 5%. It is mild, non-irritating, non-sensitizing, and non-comedogenic - which makes it suitable for sensitive, compromised, or reactive skin types. Additionally, Biosaccharide Gum-4 is considered a skin-friendly and environmentally safer alternative to synthetic film-formers and conditioning agents.
