                                                       Ethyl Cellulose K70 K100 for slow-release pills industry

Sustained-release tablets refer to dao formulations that slowly release the drug at a non-constant rate for a long period of time after oral administration. Therefore, zhuan is not a dose that releases the entire shu drug at a time, while plain tablets are directly disintegrated. A full dose of the drug was absorbed in one go.
Therefore, the dosage of sustained-release tablets is generally larger than that of plain tablets, and does not need to be administered multiple times a day in order to maintain a stable blood concentration like plain tablets. Sustained-release tablets are generally administered less frequently than plain tablets.

【Introduction】

Name: Ethyl Cellulose

Abbreviation: EC

Structural formula:

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 to light , heat , oxygen and wetness , and is stable to chemicals . It is resistant to alcali , dilute acid and salting liquid , soluble in some organic solvents , such as alcohol , ether, ketone , ester, aromatic hydrocarbon and halohydrocarbon , etc , and compatible to 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 .
