Methylhydroxyethyl cellulose (MHEC) is a synthetic substance that is used as a thickening and emulsifying agent in many products, including foods, pharmaceuticals, and cosmetics.
Methylhydroxyethyl cellulose (MHEC) has been shown to inhibit the activity of certain enzymes, such as amylase, lipase, and protease.
In addition to these properties, Methylhydroxyethyl cellulose (MHEC) is also known for its high degree of thermal stability and light resistance.

Methylhydroxyethyl cellulose (MHEC) can be used in a wide range of applications due to its versatility and low cost.
Methylhydroxyethyl cellulose (MHEC) is an odorless, tasteless, non-toxic white powder, can be dissolved in cold water, forming a transparent viscous solution.
With thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, moisture retention and protective colloid and other characteristics.
Due to the surface active function of aqueous solution, Methylhydroxyethyl cellulose (MHEC) can be used as colloid protective agent, emulsifier and dispersant.
Methylhydroxyethyl cellulose (MHEC) aqueous solution has good hydrophilicity and is an efficient water-retaining agent.
Methylhydroxyethyl cellulose (MHEC) contains Hydroxyethyl group, so it has good anti-mold ability, long-term storage has good viscosity stability and anti-mildew.
Methylhydroxyethyl cellulose (MHEC) is an odorless, tasteless, non-toxic white powder that can be dissolved in cold water to form a transparent viscous solution.
Methylhydroxyethyl cellulose (MHEC) has the properties of thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gelling, surface activity, moisture retention and protective colloid.
Since the aqueous solution has surface-active functions, Methylhydroxyethyl cellulose (MHEC) can be used as a colloidal protective agent, emulsifier and dispersant.
Methylhydroxyethyl cellulose (MHEC) aqueous solution has good hydrophilicity and is an efficient water retention agent.
Because Methylhydroxyethyl cellulose (MHEC) contains hydroxyethyl groups, it has good anti-fungal ability and has good viscosity stability and anti-fungal degeneration during long-term storage.
Methylhydroxyethyl cellulose (MHEC) is similar to Hydroxyethyl Cellulose (HEC) and resistant to most salts.
The presence of methyl groups results in surface activity on the intermediates methyl cellulose and Hydroxyethyl Cellulose.
Methylhydroxyethyl cellulose (MHEC), like HEC, has no thermal gel properties in boiling water.
The commercial products have a degree of substitution ranging from 1.8 to 3.0 for hydroxyethoxy MS and from 0.8 to 1.2 for methoxy DS.
The decomposition started at 260 ° C.
And the weight volume was 0.743/g.
The manufacturing process of HEMC is described in U.S. Patent Nos. 3709876 and 3903076. Methylhydroxyethyl cellulose (MHEC) can be used as an additive in cosmetics for daily use, and can also be used in latex coatings and formulation components with high resistance to enzymatic chemical attack that need to be stored for a long period of time.
Intermediate surface-active properties may also be useful in the polymerization of vinyl acetate.

Pharmaceutical Applications
Methylhydroxyethyl cellulose (MHEC) is used as an excipient in a wide range of pharmaceutical products, including oral tablets and suspensions, and topical gel preparations.
Methylhydroxyethyl cellulose (MHEC) has similar properties to methylcellulose, but the hydroxyethyl groups make it more readily soluble in water and solutions are more tolerant of salts and have a higher coagulation temperature.
