EC is a naturally occurring polymer produced from wood pulp or cotton by treatment with alkali and then ethylation of the alkali cellulose with ethyl chloride.

Different EC grade can be produced by controlling the substitution of ethoxyl groups.

 

 

Introduction
Name: Ethyl Cellulose
Abbreviation: EC
Structural formula:
N50 Ethyl Cellulose Pharmaceutical Use USP EP 0
In the formula , n stands for degree of polymerization and R for –H or –C2H5.
【Characteristics】
Ethyl Cellulose is a white to light yellowish, oderless and tastless, non-ionic polymer powder derived from cellulose through a series of chemical and physical processes.

 

 


【Solubility


In water

Practically insoluble in water and it is the only modified cellulose not soluble in water but soluble in ethanol.


In organic Solvents

 

Insoluble in glycerol and in propane-1,2-diol.

Its solubility in varying proportions in certain organic solvents depending upon the ethoxyl content:

Less than 46–48%: freely soluble in tetrahydrofuran, in methyl acetate, in chloroform and in aromatic hydrocarbon ethanol mixtures.

46–48% or more: freely soluble in ethanol, in methanol, in toluene, in chloroform and in ethyl acetate.

Application
 
Due to its insolubility in water, ethyl cellulose is mainly used as tablet adhesive and thin film coating material, etc. It is also used as retarding agent for aggregate to make various types of aggregate slow-release pills; as slow-release agent or slow-release pills for compound material when making coat; as microcapsule material to make the medical effect release continuously, and avoid the preaction of water soluble medicine.
It can be too used in any type of medicine as dispersing agent, stabilizer and water retention agent to prevent medicine from absorption and deterioration, enhance the safe storage and stability of pills.
It can even be used as adhesive, slow-release agent and moisture-repellant agent for vitamine pills and mineral pills.
