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. ThePHARM grades of Klucel HPCcomply with the monographrequirements of the NationalFormulary, European Pharmacopoeiaand the Japanese additional information on Klucel HPC,please refer to booklet 250-2F on the Aqualonweb site at hypromelloseBenecel hypromellose(hydroxypropylmethylcellulos e,HPMC) is widely used in thepharmaceutical industry due to theirability to thicken, bind and retainwater; emulsify; suspend particulates;stabilize; and form films.
