Thickening Agent Hydroxyethyl Cellulose/ HEC CAS 9004-62-0

 

Description:
Hydroxyethyl Cellulose (HEC) is produced by chemically modifying cellulose through the addition of hydroxyethyl groups. This modification enhances its water solubility and improves its performance as a thickener and rheology modifier. HEC is available in various grades, with different molecular weights and degrees of hydroxyethyl substitution, allowing for customization based on specific requirements.

Specifications:
The specifications of HEC can vary depending on the manufacturer and grade. However, some common specifications include:

• Appearance: HEC is typically a white to off-white, odorless powder.
• Solubility: It is readily soluble in cold or hot water, forming clear or slightly turbid solutions.
• Viscosity: The viscosity of HEC solutions can range from low to high, depending on the grade and concentration used.
• pH Stability: HEC is stable over a wide pH range, typically between 2 and 12.
• Moisture Content: The moisture content of HEC is generally controlled to ensure product stability and ease of handling.

Applications:
HEC finds applications in various industries due to its versatile properties, including:

1. Personal Care and Cosmetics: HEC is commonly used in shampoos, conditioners, lotions, creams, and other personal care products as a thickener, stabilizer, and suspending agent. It helps provide desired texture, enhance product stability, and improve the flow characteristics.

2. Paints and Coatings: HEC is utilized as a thickening agent and rheology modifier in water-based paints, coatings, and adhesives. It improves the viscosity and application properties, allowing for better control of paint flow, leveling, and sag resistance.

3. Pharmaceutical Formulations: HEC is employed in pharmaceutical formulations as a binder, film-forming agent, and viscosity enhancer. It aids in tablet manufacturing, controlled drug release, and the preparation of topical gels and ointments.

4. Construction Materials: HEC is added to cement-based products, such as tile adhesives, grouts, and plasters, to improve workability, water retention, and adhesion. It also enhances the stability and texture of gypsum-based materials.

Features:
HEC offers several notable features, including:

• Thickening and Rheology Control: HEC imparts viscosity and rheological control to liquid formulations, allowing for better stability and control of flow characteristics.
• Water Solubility: HEC readily dissolves in water, forming clear or slightly turbid solutions, which makes it easy to handle and incorporate into formulations.
• pH Stability: HEC remains stable over a wide pH range, enabling its use in various acidic or alkaline environments.
• Compatibility: It exhibits good compatibility with other ingredients commonly used in personal care, coatings, pharmaceuticals, and construction industries.
• Film-Forming: HEC can form thin, flexible films when applied to surfaces, contributing to improved coating properties and barrier formation.

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.
