HEC/ Hydroxyethyl Cellulose CAS 9004-62-0 For Paint And Coating Industry

Hydroxyethyl Cellulose (HEC) is a non-ionic water-soluble polymer derived from cellulose, a naturally occurring polysaccharide found in plants. It is commonly used in various industries due to its unique properties. Here is a description of HEC, its specifications, applications, and features:

Description:
HEC is a white or light yellowish powder that is odorless and tasteless. It is produced by treating cellulose with ethylene oxide, which introduces hydroxyethyl groups onto the cellulose backbone. The degree of substitution (DS) of HEC refers to the average number of hydroxyethyl groups per glucose unit in the cellulose chain. HEC is available in different DS values, which affect its solubility and viscosity characteristics.

Specifications:

• Appearance: White or light yellowish powder
• Moisture content: ≤ 10%
• pH value: 6.0-8.5
• Particle size: Typically, the particle size distribution ranges from 80 to 100 mesh.

Application:
HEC has a wide range of applications across various industries, including:

1. Personal Care Products: HEC is commonly used as a thickener, binder, and stabilizer in shampoos, conditioners, lotions, creams, and other cosmetic formulations. It enhances the texture, stability, and flow properties of these products.

2. Paints and Coatings: HEC is utilized as a rheology modifier in water-based paints, coatings, and adhesives. It provides excellent thickening and suspension properties, improving the viscosity control and stability of the formulations.

3. Construction Industry: HEC is employed in cement-based products, such as tile adhesives, grouts, and self-leveling compounds. It acts as a water retention agent, improving workability, open time, and adhesion properties.

4. Pharmaceutical Industry: HEC is used as a thickening agent in oral liquid suspensions and ointments. It provides uniformity, stability, and controlled release of active ingredients.

5. Food Industry: HEC finds application as a thickener, emulsifier, and stabilizer in food products like sauces, dressings, beverages, and baked goods. It enhances the texture, mouthfeel, and stability of these products.

Features:

• Water Solubility: HEC readily dissolves in water, forming clear and viscous solutions.
• Thickening and Rheology Control: It exhibits excellent thickening and rheology control properties, allowing for precise viscosity adjustments.
• Pseudoplastic Behavior: HEC solutions show shear-thinning behavior, meaning their viscosity decreases under shear, facilitating easy application and spreading.
• pH Stability: HEC remains stable over a wide pH range, making it suitable for various formulations.
• Compatibility: It is compatible with a wide range of other ingredients commonly used in formulations.
• Film-Forming: HEC can form transparent films, providing barrier properties and moisture retention.

Hydroxyethyl cellulose is generally used as thickening agent, protective agent, adhesive, stabilizer and additive in the preparation of emulsions, gels, ointments, lotions, eye lighteners, supitories and tablets. It is also used as hydrophilic gel, skeleton material, preparation of skeleton type sustained-release preparations, and can also be used as stabilizer in food.

 

Product Function

1.Medicine Raw Material Pharmaceutical grade: this product is mainly used for pharmaceutic adjuvant that can be used as a Thickening Material,dispersing agent, emulsifier and film-forming agent etc. When used as film coating and adhesive in drug tablets, it can significantly improve the waterproofing of tablets. Besides, it can also be used as suspension, ophthalmic preparation, slow and controlled release agent skeleton and floating tablets etc.

2.With colloidal drugs as other synthetic polymers in order to prevent the separation of water and ethanol from transparent water and colloidal materials and improve water retention; and it is also used in Food And Beverage Additives, Cosmetic Raw Materials and other fields as thickener, emulsifier and to improve the rheological properties as well as other daily chemical industries, etc.

3. Industrial grade: Mainly used as dispersant in PVC production and is also the main additive of PVC preparation for suspension polymerization. In building construction, it is mainly used for external wall thermal insulation system, thermal insulation mortar, decoration mortar, masonry mortar and selfleveling mortar etc.. It is used as thickener, stabilizer, emulsifier, excipient, water retaining agent,filmforming agent etc. in the production of petrochemical products,paint remover, agricultural chemicals, printing ink, textile printing and dyeing, ceramics, papermaking, Cosmetic Raw Materials and other products. When it is applied to synthetic resin, the products obtained will be of characteristics such as regular and loose particles, suitable apparent specific gravity and good processing properties etc.,which can essentially replace gelatin and polyvinyl alcohol as dispersant.
