Hydroxyethyl Methyl Cellulose Ether

Hydroxypropyl methylcellulose is a cellulose variety whose output and consumption are increasing rapidly. It is a non-ionic cellulose mixed ether made from refined cotton after alkalization, using propylene oxide and methyl chloride as etherification agent, through a series of reactions.
Hydroxyethyl methyl cellulose ether has multiple characteristics, solubility: soluble in water and some organic solvents. Salt resistance: The product is a non-ionic cellulose ether, and it is not a polyelectrolyte, so it is relatively stable in aqueous solution in the presence of metal salts or organic electrolytes. Surface activity: due to the surface active function of the aqueous solution, it can be used as a colloidal protective agent, emulsifier and dispersant. In addition, it has thermal gelation, PH stability, mildew resistance, water retention, etc., so it is used as a thickener, film forming agent, adhesive, lubricant, suspending agent, protective colloid, emulsifier, etc. In addition to being widely used in the field of building materials, it is also an excellent raw material for cosmetics. It has various functions and effects on the skin. It can not only improve the texture of the skin, but also moisturize, whiten and resist oxidation, making the skin healthier, younger and smoother. .
