Ethyl Cellulose

Ethyl Cellulose Description

Ethyl cellulose(EC) is a non-ionic, odorless and tasteless, free-flowing, white to light tan-colored powder. It is insoluble in water but soluble in many organic solvents, such as EVA, benzene, methylbenzene, acetone, methyl alcohol, and alcohol, etc. It has 135-155℃ softening point, 0.3-0.4/ bulk density, 1.07-1.18 relative density, and 165-185℃ melting point. We have different grades of Ethyl cellulose. Our K grade is of high hardness, intensity, and heat resistance; N grade is soluble, widely compatible, and soft; T grade is soluble only in HC while insoluble in any organic solvent containing oxygen atoms.

 

Our ethyl cellulose products have the following properties:

 

Flame retardant

Good Thermal Stability and thermoplastic

Color fastness to sunlight

Good softness

Good dielectricity

alkali-resisting; weak acid-resisting

Anti-aging

Salt resistance; cold resistance, and moisture resistance

High stability and can be stored for a long time without deterioration

Compatible with various resins and multiple plasticizers.  

Easy to change color or fade when exposed to strong alkali or high-temperature environment.

Since ethyl cellulose is insoluble in water, it is mainly used as a tablet binder, film coating material, and blockers for framework materials. Besides, it can also be used to manufacture a variety of sustained-release tablets, coated sustained-release agents, and granules. Similarly, it can also be used as a material for preparing sustained-release microcapsules, in which the drug can be prevented from being dissolved in water prematurely. Moreover, it can also be used as a dispersant, stabilizer, and water retention agent to prevent the drug from getting wet or deteriorated and to extend the shelf life of the tablet.

Dissolution method:

Ethyl cellulose is added slowly, while stirring, into the solvent until it is completely dissolved. 

 

The common solvents mixed with Ethyl cellulose are hydrocarbons and alcohols. Among the aromatic hydrocarbon, benzene, methylbenzene, ethylbenzene, and xylene can be used in a dose of 60-80%. Among alcohols, methanol and ethanol can be used at an amount of 20-40%.

 

Packaging:
