Ethyl Cellulose K70 K100 for slow-release pills industry
The main purpose is to relieve the delay or even control the release of the sustained-release components of the drug in the body. The purpose is to reduce the excessive irritation of the drug to the intestine and the human body and protect the drug-receiving body; the second is that the drug needs to be continuously supplied , Which is to maintain the drug content in the blood of the drug acceptor, so as to achieve the purpose of specific drug effect.
At present, some toothpastes also have sustained-release tablets, such as a certain brand of ice toothpaste. The transparent paste contains visible sustained-release tablets, which can be released slowly during friction.
【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 .
