HYDROXYETHYL CELLULOSE occurs as a white, yellowish-white or grayish-white, odorless and tasteless, hygroscopic powder. It is a non-ionic, water-soluble polymer.
Applications of HYDROXYETHYL CELLULOSE
In various formulations
a) Ophthalmics & Topicals - Thickening agent and lubricant
b) Tablets - Binder and film coating
Water based Paints
Rheology modifier and film forming agent
Adhesive and Construction Chemicals
Provides better strength to adhevise and increase density of cement based mortars, wall putty's and tile adhesives
Basic difference between HEC and HEMC/MHEC
Cellulose ethers are derivatives of the natural material cellulose (pulp) and are used in various ways as additives to refine different products.
MHEC & HEC both are water soluble cellulose ethers.
We have MHEC for Construction Industry.
MHEC is the only cellulose derivative which has best water retention property due to high degree of 'METHOXYLATION' & that is the sole reason for which MHEC is sold for Cement based Wall Putties as well as Mortars. MHEC is also used in Cement based Tile adhesives & Grouts.
HEC has properties of thickening, pseudoplastic properties, water retention, protective colloid effects, film forming and a high level of salt tolerance best suited for industry.
In short HEC is the BEST RHEOLOGY MODIFIER for water based paints and MHEC is the BEST WATER RETAINING AGENT for construction industry.
