Sclerotium gum (Sclerotium Gum, Hydrolyzed Sclerotium Gum) is a natural polysaccharide obtained by fermentation of the soil fungus Sclerotium rolfsii. A cosmetic emulsion thickener and stabilizer that works similarly to xanthan and guar gum but with better sensory profile – gives creams a silkier texture and faster absorption. Where applied. Gel-creams, serums, masks, hydrating lotions, sensitive-skin formulas (0.2-1%). Often replaces xanthan gum in premium formulas for better tactile experience. In Spanish brands appears in Sesderma, Bioderma, ISDIN in formulas tagged as 'light texture'. Additional functions. Beyond thickening, sclerotium gum gives emulsions stability across pH values (3-10) and ionic strengths. Compatible with most cosmetic actives – vitamin C, AHA/BHA, retinol, niacinamide. Safety. EU CosIng permits use. CIR has not issued a standalone review, but mass-use experience is extensive. Hypoallergenic, non-comedogenic, non-irritating. Suitable for sensitive skin, atopics, infants.
