Mucilaginous and softening
Sodium alginate is extracted from mineral-rich brown seaweed. This fine white powder transforms into jelly when put in contact with water, creating a unique texture in the bath.
Sodium alginate is a water-soluble polysaccharide and is commonly used as a thickener or an emulsifier in the food industry, and more recently in cosmetics.
Like most ingredients derived from seaweed, sodium alginate softens and soothes the skin as well as creating beautiful and playful textures in the water.
