Water-based paint is an eco-friendly alternative to traditional solvent-based paints. It has lower levels of VOCs. It can dry quickly and is easy to clean up. HPMC cellulose is a non-toxic powder. It can dissolve fast in cold water. It is a thickener, dispersant, and stabilizer in paint formulas.
WOTAIchem is your trusted hydroxypropyl methylcellulose supplier in China. We manufacture HPMC powders under strict quality control systems. Our HPMC chemicals can be added to various paint formulas. For example, water-based paints and paint remover.

If you don't distinguish HPMC and CMC, there are 7 differences you need to know. HPMC vs CMC: their differences mainly focus on Definition, Solubility, Water Retention, Ph Stability, Enzymatic Resistance, Price and Application.
HPMC is prepared by reacting alkali cellulose with chloromethane and propylene oxide. This process mainly take place on etherification of workshop. Carboxymethyl cellulose (CMC) is a cellulose derivative formed by the reaction of alkali and chloroacetic acid.
HPMC dissolves easily in cold water and may be difficult to dissolve in hot water. But CMC is easy to dissolve in hot and cold water, and the solubility of HPMC in cold water is higher than CMC.

HPMC has better water retention than CMC. This is their big difference.
Melacoll™ HPMC remains stable in the range of pH 3~11. However, PH has a great effect on CMC, it is mainly used in gypsum rather than cement.
In a strongly alkaline environment, CMC’s viscosity will be lost. But HPMC will speed up its dissolution rate and increase its viscosity.
HPMC has better resistance to enzymes than CMC, so HPMC solution is less easily degraded by enzymes.
HPMC price is evidently higher than CMC.
CMC mainly apply to the food industry, toothpaste, diet pills, water-based coatings, detergents, and others. CMC proved to be a viable and superior alternative to HPMC as a goniometer solution. The most common applications of HPMC include tile adhesive, paints and coatings, gypsum products, putty, food, cosmetics, detergents, and eye drops, among others.
This is 7 difference between HPMC and CMC. However, whatever any products, their impact is important. If you want to know HPMC and MHEC difference, please click here.
