Differences Between Industrial Grade HPMC and HPMC for Daily Chemical Detergent


Hydroxypropyl methyl cellulose ether (HPMC) is a kind of synthetic polymer which is made from natural cellulose by chemical modification.

Cellulose ether is a derivative of natural cellulose. The production of cellulose ether is different from synthetic polymer. Its basic material is cellulose, a natural polymer. Due to the special structure of natural cellulose, cellulose itself has no ability to react with etherifying agent. However, after the treatment of the swelling agent, the strong hydrogen bonds between and within the chain were destroyed, and the hydroxyl group was released into alkali cellulose with reaction ability. After etherification agent reaction, OH group was converted into - or group to obtain cellulose ether.


Hydroxypropyl methyl cellulose HPMC is a white or slightly yellow powder, and odorless, tasteless, non-toxic. It can be dissolved in the solvent mixed with cold water and organic matter to form a transparent viscous solution. Water solution has surface activity, high transparency, strong stability, and is not affected by pH. The daily chemical grade HPMC has thickening and anti freezing effects in detergents, detergents, detergents, shampoos and shower gels, and has water retention and good film-forming properties for hair and skin. With the rapid rise of basic raw materials, cellulose (antifreeze thickener) used in washing and daily chemical applications can greatly reduce costs and achieve ideal results.


Industrial grade HPMC cellulose has architectural grade, ceramic grade and daily chemical grade. HPMC itself is non-toxic, and daily chemical grade HPMC is often used in shampoo, detergent and detergent to adjust viscosity. However, if it is used as a food additive, food grade cellulose must be used.


Building materials grade hydroxypropyl methyl cellulose HPMC is generally used in mortar, putty, diatom mud and other aspects. The viscosity is generally required to be above 100000 viscosity, which belongs to high viscosity. Ceramic grade hydroxypropyl methyl cellulose HPMC is generally used as auxiliary materials for firing ceramics. Generally, it is low viscosity when it is less than 50000 viscosity. These two types can be simply measured with a rotary viscometer or experienced by directly stirring with a glass rod to feel the viscosity, which can be roughly distinguished. The viscosity of hydroxypropyl methyl cellulose used in daily chemical detergent thickener is about 200000, which is basically equivalent to that of mortar.
