Benefits of cellulose ethers for drug coating

In the pharmaceutical industry, hydroxypropyl carboxymethyl cellulose (HPMC) can be used as a drug excipient and is widely used in oral drug matrix controlled release and sustained release preparations. It is used as a release retardant material to regulate the release of drugs and as a coating material sustained release agent, sustained release pellets, and sustained release capsules. The most widely used are methyl carboxymethyl cellulose and ethyl carboxymethyl cellulose. For example, MC is often used to make tablets and capsules, or to coat sugar-coated tablets. High-quality cellulose ethers can be used in the food industry and are effective thickeners, stabilizers, excipients, water retainers, and mechanical foaming agents in various foods. Methyl cellulose and hydroxypropyl methyl cellulose are recognized as metabolically inert substances that are harmless to physiology. High-purity (purity above 99.5%) carboxymethyl cellulose (CMC) can be added to foods such as milk and cream products, condiments, jams, jellies, canned foods, table syrups, and beverages. Carboxymethyl cellulose with a purity of more than 90% can be used in food-related aspects, such as in the transportation and storage of fresh fruits. This kind of plastic wrap has the advantages of good preservation effect, less pollution, no damage, and easy mechanized production.
