Croscarmellose Sodium
Croscarmellose sodium is a cross linked polymer of carboxymethyl cellulose sodium. Cross linking makes it an insoluble, hydrophilic, highly absorbent material, resulting in excellent swelling properties and its unique fibrous nature gives it excellent water wicking capabilities. It is an odourless, relatively free flowing, white powder.
APPLICATIONS IN PHARMACEUTICALS
- In formulations as a disintegrant for capsules tablets and granules
- In wet granulations, CICSEL can be added in both the wet and dry stages of the process so that the wicking and swelling ability of the disintegrant is best utilized.
- Concentrations of normally 2% w/w is used in tablets in direct compression and 3% w/w in tablets inwet-granulation process.
- Suitable for products where the use of starch products is contraindicated.
- Works by attracting water into the tablet pores (wicking) followed by swelling.
