PRODUCT INTRODUCTION
Hydroxypropyl methylcellulose (HPMC) is a non-ionic cellulose ether obtained by etherification under alkaline conditions using refined pure cotton as raw material and propylene oxide and methyl chloride as etherifying agents. It is an odorless, non-toxic white or off-white powder that can be dissolved in cold water and swell into a transparent or slightly turbid colloidal viscous solution. The degree of substitution is generally 1.2-2.0. Its properties vary depending on the ratio of methoxy content to hydroxypropyl content. Main ingredients: cotton, methyl chloride, propylene oxide, and caustic soda solution.
