Hydroxy Ethyl Cellulose

Hydroxy Ethyl Cellulose HydroxyEthy Cellulose (HEC for short) is a non-ionic soluble cellulose ether, both soluble in cold and hot water, with thickening, suspension, adhesion, emulsification, film-formation, water retention, protective colloids and other properties, widely used in coatings, cosmetics, oil drilling and other industries. Appearance HEC is a white to light yellowish, oderless and tastless powder, readily soluble in hot or cold water to form a viscous gel solution. When pH in solution is within 2 to 12, the solution is quite stable.  Characteristic Since HEC group is nonionic one in water solution, it won't be reacted with other anions or cations and insensitive to the salts. But HEC molecule is capable of generating esterification, etherification and acetal reaction, so it is possible to make it insoluble in water or improve its properties. HEC also has good film-forming ability and surface activity.   Specification Hydroxyethy Cellulose Test items Testing standards Appearance white to light cream, free-flowing powder Molar substitution degree(MS) ≥2.3 Brookfield RV 2% 250-180000 mPa.s Loss on drying ≤5% Residue on ignition ≤5% Ash content ≤5% light ratio (2% Solution) ≥85% PH ( 1% aqueous solution, 25℃ ) 6.0-8.0 Particle Size min. 98% pass through 100 mesh   Application Application Fields Application Range Function Oil-drilling Oil drilling Viscosifier and water loss controller Painting Latex paint, polymer emulsifying Thickening Construction Cement, mortar Thickening, water-retaining, retarding Cosmetics Toothpaste, shampoo, Cream Thickening, stabilizing Ceramics Enameling Water-retaining Paper-making Sizing Thickening, water- retaining Pharmaceutical Lotion, Ointment Thickening   Packing N.W.: 25±0.25kg / package, 16 ton/ 20’FCL with pallets, 18MTS/20’FCL without pallets.
