It is also used as a thickening agent in cosmetic formulations, improving the texture and viscosity of the products to which it is added. Hydrolyzed algin is another form of algin obtained by breaking down larger molecules into smaller fragments, increasing its solubility and ability to penetrate the skin. Algin is typically a fine, white powder and is often used in combination with other natural ingredients such as glycerin and aloe vera. It is found in a wide range of cosmetic products, including face masks, moisturizers and body lotions. The chemical formula for Algin is (C6H7NaO6)n. https://cosmetics.specialchem.com/inci-ingredients/algin
