Methylcellulose is a chemical compound derived from cellulose, a natural polymer found in plant cell walls. It is commonly used as a thickening agent, emulsifier, and stabilizer in various food products, pharmaceuticals, and cosmetics. Methylcellulose is known for its ability to form gels when heated and return to a liquid state upon cooling, making it useful in cooking and baking. In addition to its culinary applications, methylcellulose is often used in the production of dietary supplements and medications due to its non-toxic nature and ability to retain moisture. It is also employed in construction materials and personal care products, highlighting its versatility across different industries.
