Hydroxyethyl methyl cellulose properties

Feature 11 (1-6)

01
Solubility:
It is soluble in water and some organic solvents. It can be dissolved in cold water. Its maximum concentration is only determined by the viscosity. The solubility changes with the viscosity. The lower the viscosity, the greater the solubility.

02
Salt resistance:
The product is a non-ionic cellulose ether and is not a polyelectrolyte, so it is relatively stable in aqueous solution in the presence of metal salts or organic electrolytes, but excessive addition of electrolytes can cause gelation and precipitation.

03
Surface activity:
Due to the surface active function of the aqueous solution, it can be used as a colloid protective agent, an emulsifier and a dispersant.

04
Thermal Gel:
When the product aqueous solution is heated to a certain temperature, it becomes opaque, gels, and forms a precipitate, but when it is continuously cooled, it returns to the original solution state, and the temperature at which such gelation and precipitation occur mainly depends on their lubricants. , suspending aid, protective colloid, emulsifier, etc.

05
metabolism:
Metabolically inert and low odor and aroma, they are widely used in food and medicine because they are not metabolized and have low odor and aroma.

06
Mildew resistance:
It has good antifungal ability and good viscosity stability during long-term storage.
