Hydroxyethyl Cellulose is a white, free-flowing granular powder, prepared from the alkali cellulose and ethylene oxide (or ethylene chlorohydrin) by etherification, and belongs to non-ionic soluble cellulose ethers, both soluble in hot and cold water. Owing to good thickening, suspending, dispersing, emulsifying, film-forming, water-protecting and providing protective colloid properties, Hydroxyethyl Cellulose has been widely used in oil exploitation, coating, building, medicine, food, textile, papermaking, polymerization and other fields.
In the daily chemical industry such as toothpaste, soap, lotion and cosmetics, and ointment, Hydroxyethyl Cellulose acts as a thickener, dispersing agent, binder and stabilizer to increase the density, lubrication, and mercerized appearance of products. SidleyCel' Hydroxyethyl Cellulose products are applicable to personal care and cosmetics, with purity over 95%. The reliable quality and high stability have been recognized by customers.
Hydroxyethyl Cellulose has wide applications: In the paint industry, Hydroxyethyl Cellulose can provide the latex paint especially high PVA paints with excellent coating performance. When the paint is thick paste, no flocculation will occur. Hydroxyethyl Cellulose has higher thickening effects. It can reduce the dosage, improve the cost-effectiveness of formulation, and enhance the washing resistance of paints. Hydroxyethyl Cellulose is all treated by the delayed dissolution, and in the case of adding dry powder, can effectively prevent caking and make sure hydration starts after the adequate dispersion of Hydroxyethyl Cellulose powder.
Hydroxyethyl Cellulose of daily-chemical grade has good mildew-resistant performance, system thickening and rheology modifying functions, as well as good water retention and film formation, and gives the final product full visual effects and all necessary application performance. The surface-treated Hydroxyethyl Cellulose has cold water solubility, and dry powder can be used and directly added into water. Good dispersion of the product in water can avoid clumping of product, and the occurrence of uneven dissolution. The final aqueous solution is uniform, continuous and full.
Hydroxyethyl Cellulose can be used as a thickener and cementing agent of workover fluid for oil wells. It helps to provide with the clear solution with a low fixed content, thus greatly reducing the damage to the structure of oil wells. The liquid with Hydroxyethyl Cellulose used for thickening gets easily decomposed by the acid, enzyme or oxidizing agent, and greatly enhances the ability of hydrocarbon recovery. In the oil well fluid, hydroxyethyl cellulose is used as the carrier of proppant. These fluids can be easily decomposed by the the processes described above.

Ethyl hydroxyethyl cellulose: [C6H7O2 (OH)x (OC2H5)y [O(CH2CH2O)mH]z]nEthyl Hydroxyethyl Cellulose is cellulose in which both ethyl and hydroxyethyl groups are attached to the anhydroglucose units by ether linkages. Ethyl hydroxyethyl cellulose is prepared from cellulose by treatment with alkali, ethylene oxide and ethyl chloride. The article of commerce may be specified further by the viscosity of its aqueous solutions. more Hydroxyethyl cellulose is is a thickening or gelling agent made from cellulose. It is used as an ingredient in solutions such as household cleaning products, soaps, and shampoos. Hydroxyethyl cellulose thickens these solutions and reduces the amount of suds or foam they. This increases the cleaning effect because colloids surround the dirt particles, which then wash away with water. more hydroxyethylcellulose (HEC), a nonionic, water-soluble polymer, is a white, free-flowing granular powder. It is made by reacting ethylene oxide with alkali-cellulose under rigidly controlled conditions. Purified hydroxyethylcellulose for personal care and cosmetic applications is typically sold at 95.0 percent minimum purity (dry basis).Solutions of hydroxyethylcellulose are pseudoplastic or shear-thinning. As a result, personal care products formulated with hydroxyethylcellulose dispense rich and thick from the container, but spread easily on hair and skin.hydroxyethylcellulose has applications in multiple markets including adhesives and sealants, advanced ceramics, building and construction, ceramics, pottery and porcelain, commercial and institutional, oil and gas technologies, metal castings and foundry, paint and coatings, personal care pharmaceutical and pulp and paper. more Hydroxyethyl cellulose is a gelling and thickening agent derived from cellulose. It is widely used in cosmetics, cleaning solutions, and other household products.[1] Hydroxyethyl cellulose and methyl cellulose are frequently used with hydrophobic drugs in capsule formulations, to improve the drugs' dissolution in the gastrointestinal fluids. This process is known as 'Hydrophilization'.Hydroxyethyl cellulose is the main ingredient in the lubricant KY Jelly. It is also a key ingredient in the formation of big bubbles as it possesses the ability to dissolve in water but also provide structural strength to the soap bubble. more There are different grades of Hydroxethyl Cellulose with varying formulation requirements. Hydroxethyl Cellulose (HEC) is a free-flowing, extremely easy to use, granular powder that easily disperses into room temperature water without clumping or forming 'fish-eyes'. We are currently the only distributor for this particular Hydroxyethcellose (HEC) product, therefore other Hydroxethyl Cellulose products will likely require different formulation technique and procedures.Hydroxethyl Cellulose (HEC) has an exceptional skin feel and is the perfect ingredient to make crystal clear serums for water soluble active ingredients. It can also be used to make crystal clear, water soluble hair styling gels. In addition, Hydroxethyl Cellulose (HEC) offers excellent functionality when used in the water phase of emulsions to build viscosity and stability. However, Hydroxethyl Cellulose (HEC) is not an emulsifier and will not emulsify oils into water. more Hydroxyethylcellulose (HEC) is a non-ionic rheology modifier derived from cellulose (wood), a renewable raw material. Like all polymers (gums), the use of Hydroxyethylcellulose in your personal care products will change the flow properties of water. This can benefit a variety of personal care products allowing you to create crystal clear serums, softer creams and lotions, and enhanced cleansing systems.more In oildrillingA nonionic cellulose derivative with hydroxyethyl groups attached to the polymer structure. Hydroxyethylcellulose is used as a viscosifier in brines and saline fracturing fluids, workover fluids, completion fluids and drill-in fluids. It gives pseudoplastic rheology but essentially no gel strength development. Hydroxyethylcellulose offers little fluid-loss control, other than its rheological effects. Hydroxyethylcellulose is seldom used in drilling fluids. Cellulose fibers are reacted with caustic soda and ethylene oxide to form Hydroxyethylcellulose. Hydroxyethyl groups attach to the OH groups of the polysaccharide structure by ether linkages. A high degree of substitution (from 1.5 to 2.5 out of 3 maximum) gives Hydroxyethylcellulose superior solubility in water and various brines. Being nonionic, it is not precipitated by hardness ions and disperses well at high salinity. Hydroxyethylcellulose is not degraded by common bacteria. more Hydroxyethyl Cellulose or HEC is a thickening agent that is used in cosmetics. There are a lot of thickeners, as well as reasons to use certain thickeners. Cetyl Alcohol is a great thickener and feels really wonderful, but some people might be sensitive to it. Cetearyl Alcohol is a nice thickener, but might not have quite as nice of a feel to it. Xanthan Gum, which is a food additive and also a cosmetic, can be used in place of HEC, but has some ionic incompatibility issues in certain products, which is why I alternatively use HEC in some situations. Both Xanthan Gum and HEC are actually water stabilizers and help to create a more stable emulsion in an unstable oil-and-water environment, which is what any lotion is. Basic chemistry states that oil and water do not mix. When you make lotion, you must add an emulsifier, but sometimes an emulsifier alone does not create the most stabile environment and a water stabilizer is needed. Depending on the situation, I use both HEC and Xanthan gum. more Hydroxyethylcellulose History and OriginHydroxyethylcellulose is derived from cellulose and is used in many industries such as skin care products, hair care products, cleaning solutions and many other common household products that are used every day by the general public. Its importance in the field of medicine makes it an indispensable ingredient in making hydrophobic drugs and medications that are usually packaged in capsule forms. Hydroxyethylcellulose makes this medication easily absorbed by the walls of the gastro intestinal system.Hydroxyethylcellulose Modern UsesDuring today's modern times, Hydroxyethylcellulose was created to improve the quality of many care and cleaning products so as to dissolve perfectly in water. This makes this an indispensable additive in most personal care items such as shampoos, body washes, moisturizing gels, shower and bath products.In the cosmetic industry, Hydroxyethylcellulose is perfect in thickening cosmetic emulsions such as concealers, foundations and mascaras. It makes these products easy to apply onto the skin and to remain on the skin as well.This chemical is also found in many household cleaners, household products and other personal care items. more

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:
HEC can be used in gypsum, cement, lime and mortar systems, tile paste and mortar. In the cement component, it can be used as a retarder and water-retaining agent. In the surface treatment of siding operations, it is used in the preparation of latex, which can pre-prepare the surface and relieve the pressure on the wall, so that the effect of painting and surface coating is best; it can be used as a thickener for wallpaper adhesive.
HEC can improve the performance of gypsum mortar by increasing the hardening and application time. In terms of compressive strength, torsional strength and dimensional stability, HEC has the best effect than other celluloses.
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.
HEC with a certain molar substitution degree, which can play a better effect in the process of catalyzing and protecting colloidal polymerization; in controlling the growth of polymer particles, stabilizing latex performance, low and high temperature resistance, and resistance to mechanical shearing, HEC can play a better effect. During the polymerization reaction of latex, HEC can protect the concentration of colloid within a critical range, and control the size of polymer particles and the degree of freedom of reactive groups.
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.
Hydroxyethyl cellulose (HEC) can effectively suspend solid poisons in water-based sprays.

HEC can play a role in adhering toxins on leaves when applied in spraying operations; HEC can be used as a thickening agent for spray emulsions to reduce drug drift and increase the effect of foliar spraying.
HEC can also be used as a film-forming agent for seed coating agents; as a binder for tobacco leaf recycling.
The latex paint containing HEC component has the properties of fast dissolution, low foam, good thickening effect, good color expansion and stability. Its non-ionic properties help stabilize in a wide range of pH values ''and allow a wide range of formulations.
The most outstanding performance of XT series products is to add thickener to water to control hydration at the beginning of pigment grinding.
The high-viscosity grades XT-20, XT-40, XT-50 are mainly developed and used in the production of water-soluble latex paints, and the dosage is smaller than other thickeners.
HEC can be used as a glazing agent for paper and cardboard and a protective glue for ink. It has the advantage of not being affected by paper size in printing, and can be used for printing high-quality images. At the same time, it can also reduce costs due to its low surface permeability and strong gloss.
It can also be used for printing on any size paper or cardboard or calendar printing. In the sizing of paper, the usual dosage is 0.5 ~ 2.0 g/m2.
In the paper making process, HEC has other excellent properties, including compatibility with most gums, resins and inorganic salts, instant solubility, low foam, low oxygen consumption and the ability to form a smooth surface film.
In ink manufacturing, HEC is used in the production of water-based copying inks, which can dry quickly and have good color diffusion without adhesion.
HEC has long been used for sizing, dyeing and finishing of yarns and fabric materials. This glue can be washed away from the fibers by washing with water. In mixing with other resins, HEC can be widely used in fabric treatment. It is used as a forming agent and adhesive in glass fiber, and as a modifier and adhesive in leather slurry.
HEC are pseudoplastic, that is, they become thinner under shear, but can quickly return to high viscosity control and improve the clarity of printing and dyeing.
HEC can control the release of water and allow it to flow continuously on the printing and dyeing roller without adding adhesive. Controlling the release of water allows more open time, which is conducive to the containment of the filler and the formation of a better adhesive film without significantly increasing the drying time.
When the concentration of HEC XT-4 in the solution is 0.2% to 0.5%, it can improve the mechanical strength of the non-woven adhesive, reduce the wet cleaning cotton on the wet material roll, and increase the wet strength of the final product.
HEC XT-40 is an ideal adhesive for printing and dyeing of non-fabrics, and can obtain clear and beautiful images.
HEC can be used as an adhesive for acrylic coatings and an adhesive for non-fabric processing. It is also used as a thickener for fabric primers and adhesives. It does not react with fillers and is still effective at low concentrations.
In the dyeing of carpets, such as the Custers continuous dyeing system, few other thickeners can match the thickening effect and compatibility of HEC. Because of its good thickening effect, easily soluble in various solvents, low impurity content does not interfere with dye absorption and color diffusion, so printing and dyeing are not affected by insoluble gel (this insoluble gel can cause spots on the fabric) and Uniformity limitation of high technical requirements.
