Hydroxy Ethyl Cellulose (HEC)

Hydroxyethylcellulose (HEC) is a white to off-white polymer powder, non-toxic, odorless, and easily soluble in water. Insoluble in general organic solvents. It is prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chlorohydrin). It is a non-ionic soluble cellulose ether. Because HEC can be widely used in the daily chemical fields of building materials and detergents, it has good thickening and water retention properties.

1. Soluble in water and some organic solvents (WATER-SOLUBLE)

Can be dissolved in water, its highest concentration is only determined by the viscosity, the solubility changes with the viscosity, the lower the viscosity, the greater the solubility.

2. Non-ionic (NON-IONIC)

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, but excessive addition of electrolytes can cause gelation and precipitation

3. SURFACE ACTIVITY

Due to the active function of the aqueous solution, it can be used as a colloidal protective agent, emulsifier and dispersant

4. THERMAL GELS

When the product aqueous solution is heated to a certain temperature, it becomes opaque and the gel forms a precipitate. However, when it is continuously cooled, it returns to the original solution state. The temperature at which this gelation and precipitation occurs mainly depends on their lubricants and suspending agents. Protective colloid. Emulsifier, etc.

5. FILM FORMATION

Can form a transparent, tough and flexible film with good oil resistance and water resistance

6. Mildew resistance

Has relatively good anti-fungal ability. Good viscosity stability during long-term storage.
