Factors Affecting Water Holding Capacity Of HPMC

The water retention of hydroxypropyl methyl cellulose ether decreased with the increase of temperature, and the fineness also requested that the particle size of 20~ 60 percent was smaller than 63um. The appearance immediately dissolved and formed the gel to wrap the material to prevent the water molecules from continuing to infiltrate,
