Hydroxycellulose
What is Hydroxycellulose?
Hydroxycellulose is a water-soluble polymer derived from natural cellulose, a polysaccharide found in plant cell walls such as cotton fibers and wood pulp. It undergoes etherification, where hydroxyethyl groups are added to the cellulose chain, resulting in a non-ionic, hydrophilic compound. Primarily used in cosmetics as a rheology modifier, it falls into categories like viscosity controllers and emulsion stabilizers. In formulations such as lotions, gels, and cleansers, it works by swelling in water to increase thickness, creating a smooth, spreadable consistency. This prevents ingredient separation, improves application feel, and supports even distribution without adding oiliness, making it ideal for lightweight aqueous products.
