Hydroxyethyl Cellulose HEC


Hydroxyethyl cellulose (HEC) is a non-ionic cellulose ether made from a natural polymer material cellulose as a raw material through a series of etherification. It is an odorless, tasteless, non-toxic white powder or granules, which can be dissolved in cold water to form a transparent viscous solution, and the dissolution is not affected by the PH value. It has the characteristics of thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, surface activity, moisture retention and salt resistance. Widely used in coatings, cosmetics, oil drilling and other industries.

Application

HEC is used in industry as agents of dispersing,water-holding, thickening, suspending, film-forming, stabilizing etc.For example,in emulsion coating,it plays a role of dispersing and protecting gels,enhancing reaction stability of agglomerate system,ensuring homogeneous distribution of pigment and stuffing, and providing effect of thickening, improving fluidity.

In building construction,used as thickening agent and cohesive agent to improve the fluidity and workability, increase initial gelling strength and avoid cracking. Used in brushing and cohering plaster,it may obviously raise water-holding and coherence strength.Used in daily-use articles such as toothpaste it gives the article a good physical and chemical property,making it good in shape,long period of storage, hard be dry and permeated.

In skin and hair protective articles,it can increase material density, adding lubrication and smoothness.Besides,it finds wide application in ink, textile dyeing & printing,paper making, pharmaceuticals, food, agriculture,forestry etc.
