KimaCell® MHEC MH150M methyl hydroxyethyl cellulose is made from cotton and wood through alkalization, ethylene oxide and methyl chloride etherification.
MHEC is a non-ionic cellulose mixed ether, MHEC molecular structure [C6H7O2(OH)3-m-n(OCH3)m(OCH2CHOHCH3)n]x. Due to the different proportions of methoxyl and hydroxyethyl content in MHEC, different viscosity, and different uniformity of product substitution, it becomes different varieties and different grades of products with different performances. MHEC has good dispersing, emulsifying, thickening, bonding, water-retaining and gel-retaining properties, soluble in water, and also soluble in ethanol and acetone below 70%. The special structure of MHEC can also be directly soluble in ethanol.

KimaCell® MHEC MH150MS methyl hydroxyethyl cellulose is soluble in water and some organic solvents. It can be dissolved in cold water. Its maximum concentration only depends on the viscosity. The solubility changes with the viscosity. The lower the viscosity, the greater the solubility. MHEC products are non-ionic cellulose ethers and are not polyelectrolytes, so they are relatively stable in aqueous solutions when metal salts or organic electrolytes exist, but excessive addition of electrolytes can cause gelation and precipitation.
Due to the surface active function of the aqueous solution, MHEC can be used as a colloidal protective agent, emulsifier and dispersant.
When the aqueous solution of MHEC products is heated to a certain temperature, it becomes opaque, gels, and precipitates, but when it is continuously cooled, it returns to the original solution state, and the temperature at which such gels and precipitates occur mainly depends on their lubrication. agent, suspending agent, protective colloid, emulsifier, etc.
