Component Specifications

Definition
Cellulose polymer chains are linear polysaccharides composed of β(1→4) linked D-glucose units, specifically processed to pharmaceutical-grade microcrystalline cellulose standards. These chains form the structural backbone of MCC, providing compressibility, binding properties, and controlled disintegration in solid dosage forms through hydrogen bonding and mechanical interlocking.
Working Principle
The cellulose polymer chains function through intermolecular hydrogen bonding between hydroxyl groups on adjacent glucose units, creating a three-dimensional network that provides mechanical strength. During tablet compression, these chains deform plastically and form new hydrogen bonds, resulting in cohesive tablets with controlled porosity for optimal drug release.
