Formula IngredientViscosity Controlling, Emulsion Stabiliser

Cellulose Gum

INCI: Cellulose Gum

Cellulose Gum (also known as carboxymethyl cellulose or CMC) is a cellulose derivative obtained by chemically modifying natural cellulose from plant cell walls. It functions as a thickener, emulsion stabiliser, film-forming agent, and binding agent in cosmetic formulations. It helps control viscosity, prevent ingredient separation, and create smooth, stable product textures.
