Applications of Hydroxy Ethyl Cellulose (HEC)

HEC is the abbreviation of?Hydroxyethyl cellulose. It?is a white or light yellow, odorless, non-toxic fibrous or powdered solid, prepared by etherification of alkaline cellulose and ethylene oxide (or chloroethanol), and is non-ionic soluble cellulose ethers. As a non-ionic surfactant, it has the properties of thickening, suspending, bonding, floating, film-forming, dispersing, water-retaining and providing protective colloid functions, it can be used in various applications:

1.?Latex paints

HEC?is the most commonly used thickener in latex coatings. In addition to thickening latex coatings, it can also take the function of emulsifying, dispersing, stabilizing?and water?retaining. It is characterized by significant thickening effect, good color dispersing, film forming and storage stability. HEC?is a non-ionic cellulose derivative and can be used in a wide pH range. It has good compatibility with other materials in the component (such as pigments, additives, fillers and salts). Coatings thickened with HEC?have good rheology and pseudoplasticity under various shear rates. It can take the working?methods such as brushing, roller coating and spraying. The workability?is good, not easy to drip, sag and splash, and the leveling property is also good.

2.?Oil drilling

HEC?has viscosity increasing properties in processing and filling mud.?It helps to provide a good low-solid mud, and can reduce the damage to the wellbore to a lesser extent.?Mud thickened with HEC is easily degraded into hydrocarbons by acid, enzyme or oxidant, and oil can be recovered to a greater extent.?

In the fracturing mud,?HEC?can carry mud and sand.?These fluids can also be easily degraded by the above acids, enzymes or oxidants.

HEC can be used to formulate ideal low solids drilling fluid, which provides the largest permeability and best drilling stability.?Its fluid restraint properties can be used in the drilling of hard rock formations, and it is also applicable to the drilling of collapsed or slumped slabs.

In the operation of filling cement, HEC reduces the friction of the pore pressure cement slurry, thereby reducing the damage to the structure caused by the loss of water to a lesser extent.

3.?Personal care

HEC?is an effective film-forming agent, binder, thickener, stabilizer and dispersant in shampoos, hair sprays, neutralizers, hair conditioners and cosmetics.?Its thickening and protective colloid properties can be used in the liquid detergent and solid detergent industries.?HEC dissolves quickly at high temperatures, which can speed up the production process and improve production efficiency.?As we all know, the obvious feature of detergents containing HEC is that it can improve the smoothness and mercerization of fabrics.
