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, enhancing the consistency of sauces, dressings, and baked goods. In pharmaceuticals, it is often used in tablet formulations and as a controlled-release agent. Its versatility and non-toxic nature make it a popular choice across multiple applications.
