Products Description
Hydroxypropyl methylcellulose (HPMC) is a nonionic, high-molecular-weight cellulose ether obtained by chemically modifying natural cellulose sources such as cotton fibers and wood pulp through alkalization and etherification processes. It appears as a white or off-white powder or granules. The product is odorless and tasteless, offers good flowability, and is free from visible impurities.
