Methylcellulose is a type of dietary fiber that is used as a bulk-forming laxative. It is also used in a variety of other applications, such as thickening agents in pharmaceuticals and cosmetics, stabilizers in food products, and as a binder and disintegrant in tablets. Methylcellulose is usually made from cellulose, the main component of plant cell walls. When taken orally, it absorbs water in the intestine, forming a gel that can help restore normal bowel movements. It is generally considered safe and is available over-the-counter.
