Cellulose gum

Cellulose gum, also known as carboxymethyl cellulose (CMC) sodium, is a derivative of cellulose, a natural compound found in the cell walls of many plants. It is commonly used in foods and oral formulations to increase thickness, to aid in disintegration and to stabilize oil-in-water mixtures 1. CMC sodium is considered generally recognized as safe (GRAS) for use as a food additive by the U.S. Food and Drug Administration (FDA) 2. Consumption of large amounts may have a laxative effect 1.
