White Ethyl Cellulose Pharmaceutical Use

Introduction

 

Name: Ethyl Cellulose

 

Abbreviation: EC

 

Structural formula:

USP Ethyl Cellulose Pharmaceutical Use 0

In the formula, n stands for degree of polymerization and R for –H or –C2H5.

 

Characteristics:

 

Ethyl Cellulose is a kind of white grains or powder, having no smell or tastes. Its 5% soliquoid shows neutral to litmus test paper. Its specific density 1.07~1.18, heat distortion point: 135~155degree centigrade, and fire point: 330~360 degree centigrade. Ethyl Cellulose has good stability against light, heat, oxygen and wetness, and is stable to chemicals. It is resistant to alkali, dilute acid and salting liquid, soluble in some organic solvents, such as alcohol, ether, ketone, ester, aromatic hydrocarbon and halohydrocarbon, etc, and compatible with many celluloses, resin and nearly all plasticizers. Ethyl Cellulose has low combustibility, small hydroscopicity and good electric behavior. Its thin film and plastics have good mechanical strength and flexibility in a wide range of temperature.

Purpose ofApplication

 

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.
