Pharmaceutical Excipients and Coating Systems
PharmaceuticalExcipients andCoating SystemsKlucel hydroxypropylcelluloseKlucel hydroxypropylcellulose(HPC) provides a remarkable set ofphysical properties for tablet binding,modified release and film Coating . Itcombines organic solvent or aqueoussolubility, thermoplasticity andsurface activity. Low viscosity E andL types are widely used for premiertablet binding with low use levels(2-6%) and improved adhesion andflexible Coating applications. Regularparticle size materials are used in wetprocessing and the X-grind materialfor dry processing. Many viscositytypes are used for modified releasematrix Systems . Low molecularweight Klucel HPC polymers, duePharmaceutical Excipientsto their thermoplastic behavior andsuperior flow properties, findapplications in melt extrusion.
Aqualon® ethylcellulose Aqualon® ethylcellulose (EC) is soluble in a wide range of organic solvents. Typically, EC is used as a non-swellable, insoluble component in matrix or coating systems.
