Algin
Algin, also known as Sodium Alginate, is a large polysaccharide (sugar molecule) derived from brown seaweed. It is primarily used as a gelling and viscosity-controlling agent in cosmetic formulations. When combined with calcium salts, it forms a rigid gel, which is the basis for so-called "rubber masks." Its official CosIng functions include binding, masking, and viscosity controlling.
