    Brief Overview

    Hydroxypropyl methylcellulose (HPMC) or known as Hypromellose refers to methylcellulose ethers. This compound is used as a binder, film former, and thickening agent in food. It is a popular type of binder because its rapid formation of a uniform, strong, and viscous gel layer. The physical appearance of this substance is white granular, odorless, and tasteless.

    Manufacturing Process

    The manufacturing started from reacting the toluene with isopropyl alcohol in a reactor. The next step was to add the purified cotton and the mixture was added to the mixture of methyl chloride and the propylene oxide. Esterification reaction was also occurred to yield the final product. The last step was to centrifuge the mixture to separate the product form by product and dried the final product, which was the Hydroxypropyl methylcellulose.
