At present, the most widely used in the market is hydroxypropyl methyl cellulose, followed by methyl cellulose, and then carboxymethyl cellulose. The comprehensive performance of hydroxypropyl methyl cellulose is better than that of methyl cellulose, and the water retention of the two is much higher than that of carboxymethyl cellulose, but the thickening effect and bonding effect are worse than that of carboxymethyl cellulose.
