What Is Cellulose Gum?
Cellulose gum is a natural, plant-derived ingredient that is most often used as a thickener but also used as a film-forming agent. The versatility of cellulose gum makes it a valuable addition to many types of water-based formulas since it also helps control viscosity to improve how products dispense.
In addition, cellulose gum plays a role in stabilizing water-based emulsions.
This ingredient has been deemed safe as used in cosmetics by the Cosmetic Ingredient Review panel. Cellulose gum is also a food-grade ingredient, further testament to its safety. Usage levels in cosmetics and oral care products such as toothpaste range from 0.0002–20%.
