Ashland Benecel HPMC 2208K is a high-quality high-viscosity water-soluble polymer of direct compression grade hydroxypropyl methylcellulose in the Benecel 2208K series. Custom-designed for oral solid dosage form direct compression, controlled-release matrix formulations and tablet binding, it meets stringent international pharmacopoeia standards
Direct Compression Adaptation - Optimized particle morphology, excellent powder flow, direct tableting to reduce processes
Precise Sustained-Release Regulation - High-viscosity hydrophilic matrix feature, precisely regulating drug release rate for long-acting delivery
Strong Binding Enhancement - Excellent binding performance, improving tablet hardness and molding stability, ensuring content uniformity
Low Nitrite Advantage - Nitrite content below 200ppb, reducing potential impurity formation risk
Direct Compression Tablet Preparation - Used for various oral direct compression tablets to improve tableting efficiency and product stability
Controlled-Release Matrix Formulations - Used as hydrophilic matrix material to prepare long-acting controlled-release tablets and granules
Tablet Binding & Granulation - Used as binder in tablet granulation process to ensure particle formation and flowability
Pharmaceutical Film Coating - Used as formulation film coating material to improve appearance and protection performance
