Sodium alginate is extracted from kelp, a type of brown algae. It is also used as a food additive and in the production of paper and textiles.Combined with calcium salts, it forms a rigid gel used in "rubber masks."Sodium alginate is used in various cosmetic applications, including lipsticks, toothpastes, and face masks. In lipsticks, it helps prevent color transfer and prolongs the lifespan of the product. In toothpastes, it acts as a binder, providing a smooth texture and preventing ingredients from precipitating. In face masks, it is used in peel-off packs, where it forms a gel that traps dirt and impurities, and in sheet masks, where it creates a soft, non-irritating material.
