Hydroxy Propyl methylcellulose is produced from highly pure cotton cellulose by special etherification in alkaline conditions. The whole process is completed under automatic monitor control and contains no active constituents, such as animal organs and grease. The product is non-ionic cellulose ether, in the shape of white powder, odorless and tasteless.
