Hydroxyethyl Cellulose
Product Description
Hydroxyethyl cellulose powder is a white or light yellow, odorless, non-toxic fibrous or powdered solid prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chloroethanol), belonging to the non ionic soluble cellulose ether class. Due to its excellent thickening, suspension, dispersion, emulsification, adhesion, film formation, moisture protection, and provision of protective colloids, hydroxyethyl cellulose powder has been widely used in fields such as petroleum exploration, coatings, construction, pharmaceuticals and food, textiles, papermaking, and polymer polymerization reactions.
Hydroxyethyl cellulose is a white, free-flowing granular powder, made by etherification of alkali cellulose and ethylene oxide (or vinyl chloride), which is a non-ionic soluble cellulose ether, both soluble in hot and cold water. Hydroxyethyl cellulose has good thickening, suspending, dispersing, emulsifying, film-forming, water retention and providing protective colloid properties.
HEC is soluble in cold and hot water.
Aqueous solutions of HEC are stable and will not gel at high or low temperatures.
HEC is a nonionic cellulose ether that maintains chemical and physical stability over a wide pH range.
HEC exhibits excellent performance as a thickener, water-holding, suspending and dispersing agent, and as a protective colloid.
HEC can be stored for several cycles without significant degradation and its viscosity remains stable in aqueous solutions.
1. Hydroxyethyl cellulose powder is generally used as thickening agent, protective agent, adhesive, stabilizer, and additive for preparing emulsions, jellies, ointments, lotions, eye cleaning agents, suppositories and tablets, as well as hydrophilic gel, skeleton materials, preparation of skeleton sustained release preparations, and as stabilizer in food.
2. Used as sizing agents in the textile industry, as well as adhesives, thickeners, emulsions, and stabilizers in the electronic and light industry sectors.
3. Used as a thickener and filtrate reducer for water-based drilling and completion fluids, it has a significant thickening effect in saline drilling fluids. It can also be used as a filtrate reducer for oil well cement. It can be cross-linked with multivalent metal ions to form gel.
4.Hydroxyethyl cellulose powder is used for the exploitation of oil-water based gel fracturing fluid, polystyrene, PVC and other polymeric dispersants by fracturing method. It can also be used as a thickener for latex in the paint industry, a humidity sensitive resistor in the electronic industry, a cement retarder in the construction industry, and a water retention agent. Ceramic industry glazing and toothpaste adhesives. It is also widely used in printing and dyeing, textiles, papermaking, medicine, hygiene, food, cigarettes, pesticides, and fire extinguishing agents.
5.Hydroxyethyl cellulose powder is used as surfactant, colloid protective agent, emulsification stabilizer for lotion such as vinyl chloride and vinyl acetate, as well as viscosifier, dispersant and dispersion stabilizer for emulsions. Widely used in coatings, fibers, dyeing, papermaking, cosmetics, pharmaceuticals, pesticides, and other fields. It also has many uses in the oil extraction and machinery industries.
6.Hydroxyethylcellulose has surface activity, thickening, suspension, adhesion, emulsification, film formation, dispersion, water retention, and protective effects in solid and liquid pharmaceutical formulations
7. Hydroxyethyl cellulose powder is used as dispersant for the production of petroleum water-based gel fracturing fluid, PVC, polystyrene and other polymerization. Hydroxyethyl cellulose powder can also be used as a thickener for latex in the paint industry, a cement retarder and water retention agent in the construction industry, a glazing agent and toothpaste adhesive in the ceramic industry. It is also widely used in industrial fields such as printing and dyeing, textiles, papermaking, medicine, hygiene, food, cigarettes, and pesticides.
