Wolff Cellulosics has launched ExcipientLine, which includes new pharmaceutical grades of carboxy methyl cellulose (CMC), as well as high purity hydroxypropyl methyl cellulose (HPMC) for tablet coating and sustained release formulations.

The company's high purity sodium carmellose (sodium CMC), marketed as Walocel C, is a high purity cellulose useful as an excipient for creams, gels, film coatings, tinctures or as a tablet disintegrant. With a purity grading of 99.5%, the excipient can be processed as a coarse or fine grained powder and can be applied for stabilising, thickening, emulsification or the suspension of actives. The company says it is ideal for the immediate release of actives.

Wolff has also developed a high purity HPMC - Walocel HM - for sustained release preparations, which meets pharmaceutical needs in terms of particle size, compressibility and quality. This provides an ideal matrix, it says, in which to embed actives for sustained release.
