Product Lineup




  • HEC dissolves readily in both cold water and hot water.
  • Aqueous solutions of HEC are stable and do not gel at either high or low temperatures.
  • HEC is a nonionic cellulose ether that remains chemically and physically stable over a wide pH range.
  • HEC shows excellent performance as athickener, as a water-retention agent, as a suspending and dispersing agent, and as a protective colloid.
  • HEC can be stored for log periods without degrading significantly, and in aqueous solutions its viscosity remains stable.

HEC (hydroxyethylcellulose) is a water-soluble polymer synthesized by the reaction of ethylene oxide with cellulose.
Aqueous solutions of HEC have excellent characterisstics for applications as thickeners, water-retention agents, suspending and dispersing agents, and as protective colloids.
In the synthesis of hydroxyethylcellulose, the avarage number of moles of ethylene oxide that combines with each mole of cellulose (MS) is used as an index.
The value of MS in HEC is controlled within 1.5 to 2.5.

Method for dissolving HEC

 It is recommended that the following procedures be used for preparing aqueous solutions.

 1)Water must be thoroughly agitated, and HEC should be added to the water gradually to prevent lumps from being allowed to form in the water.

 2)Addition of HEC should be completed before the rise in viscosity of the solution begins.

 3)Agitation should be continued until the added HEC is completely dissolved.


Dissolving HEC can be made even easier by applying either one of the methods described below.

 (1) HEC is wetted with a water-compatible alcojol before being added to the water.

   (2) HEC is blended with another powder which is either immiscible with, or has a low solubility in water.
