Sodium carboxymethyl cellulose
Also known as cellulose gum, this safe synthetic is widely used as a thickener and emulsifier in the food and cosmetic industries.
Sodium carboxymethyl cellulose is derived from natural cellulose, or plant fibre. In its dry form, it’s an odourless and flavourless white, grey or yellow powder that dissolves in water. When used in cosmetics, sodium carboxymethyl cellulose stops lotions and creams from separating and controls the thickness and texture of liquids, creams and gels.
