What is Hydroxy Propyl Methyl Cellulose (Hypromellose)?
Propylene glycol ether of Methyl Cellulose. Anhydrous glucose rights are formed by connecting to each other with ether bonds. They are compositions with a polymeric structure. Hypromellose molecular weights are determined by the percentage of hydroxyl groups, its viscosity, and the percentage of hydroxypropyl groups. It contains methoxy group and Hydroxypropyl groups in a certain ratio. How is it produced? Production of Hydroxy Propyl Methyl Cellulose Cellulose obtained from wood pulp is an unprocessed cellulose derivative. This cellulose derivative is treated with sodium hydroxide solution to produce a swollen and alkaline form of cellulose. In the next reaction in the production process, alkali cellulose is reacted with chloro methane and propylene oxide to produce methyl hydroxypropyl ethers of cellulose. The obtained product with fibrous forms is purified. An excellent product is obtained in the form of fine powder or granules. It dissolves in water as solubility. It is insoluble in Ethyl Alcohol.
