Hydroxypropyl Methylcellulose (HPMC) is a semi-synthetic polymer derived from cellulose, a natural component of plant cell walls. It is commonly used as a thickening agent, emulsifier, and film-forming agent in various industries, including food, pharmaceuticals, and cosmetics. HPMC is valued for its ability to improve texture and stability in products. In the food industry, HPMC serves as a food additive, often labeled as E464. It helps maintain moisture in baked goods and acts as a fat replacer in low-fat products. Additionally, in pharmaceuticals, HPMC is used in drug formulations and as a binder in tablets, enhancing their performance and stability.
