When it comes to hydroxyethyl cellulose, I am not a professional in this industry, and generally I don’t know much about it. You may ask: What is this? What is the use? Especially what is the use in our life? In fact, it has many functions, and HEC has a wide range of applications in the fields of coatings, inks, fibers, dyeing, papermaking, cosmetics, pesticides, mineral processing, oil extraction and medicine. Here’s a brief introduction to its functions:
1 Generally used as thickeners, protective agents, adhesives, stabilizers, and additives for the preparation of emulsions, jellies, ointments, lotions, eye cleansers, suppositories and tablets, and also used as hydrophilic gels, skeleton materials, It can be used to prepare matrix-type sustained-release preparations, and can also be used as a stabilizer in food.
2 Hydroxyethyl cellulose is used as a sizing agent in the textile industry, as an auxiliary agent for bonding, thickening, emulsifying, and stabilizing in the electronics and light industry sectors.
3 Hydroxyethyl cellulose is used as a thickener and fluid loss reducer for water-based drilling fluids and completion fluids, and has an obvious thickening effect in brine drilling fluids. It can also be used as fluid loss reducer for oil well cement. It can be cross-linked with polyvalent metal ions to form a gel.
4 Hydroxyethyl cellulose is used in fracturing to exploit petroleum water-based gel fracturing fluid, polystyrene and polyvinyl chloride and other polymeric dispersants. It can also be used as an emulsion thickener in the paint industry, a hygrostat in the electronics industry, a cement anticoagulant and a moisture retention agent in the construction industry. Ceramic industry glazing and toothpaste binder. It is also widely used in printing and dyeing, textiles, papermaking, medicine, hygiene, food, cigarettes, pesticides and fire extinguishing agents.
5 Used as surfactant, colloidal protective agent, emulsification stabilizer for vinyl chloride, vinyl acetate and other emulsions, as well as viscosifier, dispersant and dispersion stabilizer for latex. Widely used in coatings, fibers, dyeing, papermaking, cosmetics, medicine, pesticides, etc. It also has many uses in oil exploration and machinery industry.
6 Hydroxyethyl cellulose has surface active, thickening, suspending, binding, emulsifying, film-forming, dispersing, water-retaining and protective functions in pharmaceutical solid and liquid preparations.
