Product Description

Hydroxyethyl Cellulose 

Chemical name:Hydroxyethyl Cellulose(HEC) 


(Meet the requirements of USP, EP)




Molar substitution(MS)




Non-soluble substance(%)




Transmittance(2% by weight)




Viscosity(mPa.s)20% aqueous solution at 20℃


Preparation of HEC solution

Add the necessary clean water to vessel.

But HEC to the water while stirring slowly, until all material completely wet.

Add other compositions after HEC totally dissolves.

Surface-treated HEC should be distributed in water, and modified PH value to 8-10 by alkali or NH4OH after all materials completely wet.


The product is a white or light yellow powder with odourless and tasteless, 99% passes through 40 mesh seieve.

Softening temperature:130-140℃

Bulk density :0.35-0.61g/ml

Decomposing temperature: 205-210℃. The burn velocity is slow

Equilibrium moisture content(at23℃): 6% at 50% RH, and 29% at 84% RH.

It dissolves in both cold and very small when PH value is around 2-12, but it reduces when PH value exceeds this range. The surface-treated HEC can dissolve only when PH value is modified to basicity.


Reaction auxiliary agent

HEC is used in the polymerization of viny acetate. In order to improve the emulsion stability in broad PH value range. It also makes additives for many other suspended polymerization.

Petroleum well drilling

In many kinds of mud needed in petroleum well drilling, as a thickening agent. HEC makes mud have excellent flow ability and stability. In well drilling, it can raise the carring ability of mud, and inhibits a lot of water to inter oil layer.

Building construction and materials

HEC is an effective thickening agent and binder because of its good water conserving, put it into mud in order improve the mud’s flow ability, to put off water evaporating time, raise the initial intensity of concrete and avoid crcak .

Tooth paste

HEC can keep the stability of tooth paste because of its high anti-salt and anti-acid capability. In addition, it makes tooth paste hardly dry.


It is packed in fiber drum and lining with polyethylene film bag. Net weight 15kg. Moisture must be avoided.
