HPMC is a nonionic water-soluble cellulose ether which is derived from natural cellulose (pulp & cotton).The cellulose reacts with Sodium hydroxide solution to produce an alkali cellulose , then alkali cellulose reacts with etherification agents such as methyl chloride, propylene oxide or ethylene oxide to get hydroxy propyl methyl cellulose. Although cellulose contains many hydrophilic hydroxyl groups, it will not dissolve in water. That is because hydroxyl groups can create strong intermolecular hydrogen bondings, and form crystal structures to prevent water flowing into the interval between cellulose molecules.
During the etherification phase, some hydrogen atoms of the hydroxyl groups of cellulose are substituted by methyl groups (-CH3), hydroxypropyl groups (-CH2CHOHCH3), or hydroxyethyl groups (-CH2CH2OH), and these substituents can eliminate intermolecular hydrogen bondings to make Yuming product water-soluble.
Compared with other water soluble polymers, the water solutions of Yuming products in high concentration has higher viscosity and viscoelasticity, so Yuming products can enhance the shape retention of extruded ceramics and cement products.
Solubility and Thickening Ability in Cold Water:
HPMC dissolve in cold water and forms a transparent viscous solution.
Which make HPMC could be added into detergent liquid so reduce their cost and enhace their effect.
