cellulosics
klucel™ hydroxypropylcellulose
Klucel™ hydroxypropylcellulose (HPC) provides a remarkable set of physical properties for tablet binding, modified release, film coating, and hot melt extrusion. The versatility of Klucel™ HPC is apparent in a variety of pharmaceutical applications. Low molecular weight grades provide not only unmatched, efficient tablet binding but also adhesive and elastic tablet coating. They can also be used in melt-extrusion applications. High molecular weight grades are typically used for modified release, especially in matrix tablets.
benecel™ XR and XRF HPMC – grades: K4M, K15M, K100M, K200M
Benecel™ XR and XRF are high-viscosity grades of HPMC with optimized polymer structure and particle morphology for use in matrix controlled-release systems.
features and benefits
- enhanced compactibility at high tableting speeds vs standard grades
- optimized polymer structure and particle morphology
- consistent particle size distribution and bulk density
- fine particle size grades available (XRF)
aqualon™ ethylcellulose and Ashland® EC pharm ultra
Aqualon™ ethylcellulose (EC) and Ashland® EC pharm ultra are nonionic ethyl ethers of cellulose, soluble in a wide range of organic solvents.
Aqualon™ EC is produced using an aqueous slurry based process while Ashland® EC is produced using an organic solvent based process. Typically, ethylcellulose is used as a non-swellable, insoluble component in matrix or coating systems. When water-soluble binders cannot be used in dosage processing because of water sensitivity of the active ingredient, ethylcellulose is often chosen.
vinyl pyrrolidones
polyplasdone™ crospovidone
Polyplasdone™ crospovidone superdisintegrants are synthetic, insoluble, but rapidly swellable, crosslinked homopolymers of N-vinyl-2-pyrrolidone. Polyplasdone ™ crospovidone particles are granular and porous compared with other superdisintegrants. The high surface area combined with unique chemistry results in high interfacial activity that enhances the dissolution of poorly water-soluble active pharmaceutical ingredients (APIs) in a way that is not possible with other disintegrant technologies.
bioresorbable polymers
viatel™ bioresorbable polymers
viatel™ features and benefits
o excellent product quality
o high purity
o stock and custom made to order grades available
o no residual solvents
o available in granule and powder forms
cyclodextrins
CAVAMAX*, CAVASOL*and cavitron™ cyclodextrins
The molecular structure of Cavamax, Cavasol and Cavitron cyclodextrins creates a bucket-like cavity that can complex with molecules or functional groups on molecules to improve solubility of poorly soluble compounds. The same mechanism makes these excipients capable of masking unpleasant taste/odor and stabilizing APIs that are prone to degradation.
film coating systems
aquarius™ film coating systems for immediate release
