Hydroxyethyl cellulose is derived from cellulose. It’s nature’s most abundant biopolymer, found in the cell walls of plants as well as in wood and cotton. In addition to being a construction-grade additive, HEC is also used extensively in the daily chemical industry as a thickening agent.

HEC is extracted from natural polymers. It has a white or yellow-white granular or powdered appearance and is soluble in cold water.

HEC is a non-biodegradable and biocompatible polymer.

Hydroxyethyl cellulose powders are mainly used for real stone paint, emulsion paint, and inorganic waterborne coatings.

To create aqueous solutions, certain protocols should be followed:

It’s important to gradually achieve thorough agitation while adding the HEC to prevent lump formation in the water. This process must be done before the viscosity begins to rise.

Agitation must be continuous until all of the HEC is fully dissolved. To simplify this process, one may look into wetting HEC with compatible alcohol or blending it with another powder with either low solubility or immiscibility with water, thus avoiding clumps and making it easier to prepare aqueous solutions.

HEC is produced by reacting purified cellulose with sodium hydroxide to form swollen alkaline cellulose. Subsequently, the mixture is reacted with ethylene oxide to create a series of Hydroxyethylcellulose ethers.
