Carboxymethyl cellulose, also known as CMC, is a versatile and widely used compound derived from cellulose, a natural polymer found in plants. This white, odourless powder is a popular ingredient in various industries, including food, pharmaceuticals, and personal care products. In the food industry, CMC acts as a thickener, stabiliser, and emulsifier, enhancing the texture and consistency of products like ice cream, salad dressings, and baked goods. Its ability to bind water and form gels makes it an ideal choice for controlling viscosity and preventing separation in sauces, gravies, and other liquid-based foods. CMC is also utilised in the pharmaceutical sector for tablet binding, controlled drug release, and as a suspending agent in liquid medications. Its non-toxic and non-allergenic nature makes it suitable for topical applications in cosmetics and personal care items, such as lotions, creams, and shampoos. With its remarkable versatility and functional properties, carboxymethyl cellulose has become an indispensable ingredient in numerous products we use daily.
