Chemicals - Hydroxyethyl Cellulose

General Description

Hydroxyethyl cellulose (HEC) is a non-ionic water-soluble polymer derived from cellulose, which is a natural polysaccharide found in the cell walls of plants. HEC is widely used in various industries for its thickening, suspending, stabilizing, and film-forming properties. It is a white to off-white powder with a high molecular weight.

HEC is created by chemically modifying cellulose through the introduction of hydroxyethyl groups. This modification enhances its solubility in water and improves its ability to interact with other substances. The degree of substitution, which refers to the average number of hydroxyethyl groups per an-hydro glucose unit in the cellulose backbone, determines the properties and performance of HEC.


1. Personal Care and Cosmetics:

HEC is widely used in personal care and cosmetic products. It functions as a thickening agent, providing viscosity and improving the texture and stability of formulations such as shampoos, conditioners, body washes, creams, lotions, and gels. HEC also helps in suspending and stabilizing particles, enhancing the overall performance and aesthetic appeal of these products.

2. Pharmaceuticals:

HEC finds applications in the pharmaceutical industry as well. It is used as a binder in tablet formulations to hold the ingredients together and improve their mechanical strength. HEC also acts as a film-former, allowing for the creation of thin, uniform films on tablets or capsules. Additionally, it serves as a viscosity modifier in topical formulations like creams and ointments, improving their consistency and spreadability.

3. Construction Materials:

HEC is utilized in the construction industry for its water retention and thickening properties. It is added to cementitious materials, such as paints, coatings, adhesives, and tile adhesives, to improve their workability, enhance adhesion, and prevent premature drying or cracking. HEC helps in maintaining the desired consistency and texture of these materials during the application and curing processes.

4. Food and Beverages:

In the food industry, HEC serves as a thickener, emulsifier, and stabilizer. It is used in various food products, including sauces, dressings, desserts, dairy products, and beverages. HEC improves the texture, mouthfeel, and stability of these formulations, ensuring proper suspension of particles and preventing separation.

5. Industrial Applications:

HEC has applications in various industrial processes. It is used as a thickening and suspending agent in paints, coatings, and inks to control viscosity and prevent the settling of pigments or other solid components. HEC also finds use in the production of detergents, as it helps stabilize formulations and enhance their rheological properties.
