Hydroxyethyl Cellulose is non-ion surface active agent. Except for dispersing, water retention and other, it has the following characters:
1. It can dissolve in hot water or cold water.
2. Good gel thickening agent
3. Better fluid adjustment
4. The strongest protection gel ability.
Solution and confecting methods
1. Put the containers to add clean water.
2. Add Hydroxyethyl Cellulose in low speed mixing;
3. Mix to make Hydroxyethyl Cellulose completely dissolve.
Packing
1,Industrial: double-bag, the outer layer of composite paper bag, inner polyethylene film bag, net weight is 20 kg/ bag or 25 kg/bag
2.pharmaceutical, food:cardboard drum, inner polyethylene film bag, net weight is 20 kg/drum or 10 kg/drum.
Application
Industrial grade products:
Hydroxyethyl Cellulose can be used in water latex paint, as suspension aggregation dispersant, used in oil and drilling, in architecture, toothpaste, etc. In addition, Hydroxyethyl Cellulose can be used in textile printing and dyeing, paper-making, daily chemicals, etc.
Pharmaceutical food grade products: Hydroxyethyl Cellulose has surface action, decentralization, water reservation and others in solid and liquid drugs.
Safety
