Hydroxypropyl methylcellulose is a non-ionic cellulose ether made from refined cotton as a raw material after a series of chemical processes. Abbreviation: HPMC. It is a white or slightly yellowish powder, which is a relatively common substance in life and a viscous mixture. It has a film-forming effect.
Method for dissolving powdered hydroxypropyl methyl cellulose
1. Put the required amount of hot water in the container and heat to about 70 ºC. Hydroxypropyl methylcellulose was gradually added with slow stirring, and hydroxypropylmethyl cellulose began to float on the surface of water, and then a slurry was gradually formed, and the slurry was cooled with stirring.
2. Mix the HPMC powder with a large amount of other powdered materials, mix it with a blender, and then add water to dissolve, then the HPMC can be dissolved without clumping and agglomeration, because each small corner has only a little HPMC powder, It will dissolve immediately in case of water.
