What is sclerotium gum?
Sclerotium gum is a natural polymer extracted by fermentation of fungi belonging to the genus Sclerotium, in particular Sclerotium rolfsii. It is appreciated in cosmetics for its thickening, stabilizing and film-forming properties, thus providing a pleasant texture to care products. Non-irritating and gentle on the skin, sclerotium gum is often used in formulations for sensitive skin because it forms a protective film that helps retain moisture. Its ability to form smooth and stable gels makes it an essential ingredient in natural care, organic products, and formulations intended for dry or reactive skin.
Sclerotium rolfsii gum is obtained by fermentation of mushrooms. It is used in our Moisturizing perfecting emulsione and our Happy Cycles Body Serum for his thickening and stabilizing properties, making it possible to improve the texture and stability of the products.
Where does sclerotium gum come from?
Sclerotium gum is obtained through the fermentation of a microscopic fungus of the species Sclerotium rolfsii. This fungus produces a natural gum which is then extracted, purified and made into a fine powder. This fermentation process produces a durable, non-irritating and environmentally friendly polymer. Sclerotium gum is prized in cosmetic formulations for its natural origin and its ability to stabilize emulsions. It is widely used in skin and hair care products for its thickening and moisturizing properties.
