1. Basic Information
Name: Microcrystalline Cellulose
Abbreviation: MCC
CAS No.: 9004-34-6
Repeating unit formula: C6H10O5
Average molecular weight: Variable, controlled by hydrolysis degree
2. Physical and Chemical Properties
Physical Properties
- Appearance: White, odorless, tasteless fine crystalline powder
- Solubility: Insoluble in water, ethanol, ether, acetone and most organic solvents; slightly swells in water; soluble in concentrated mineral acids
- Particle Size: Customizable range from 20 μm to 200 μm
- Bulk Density: 0.15–0.45 g/cm3 depending on grade
- Hygroscopicity: Slightly hygroscopic under high humidity; stable under normal ambient conditions
- Compressibility: Excellent dry binding and compression performance, widely used tablet filler
- Morphology: Short rod-like crystalline cellulose particles obtained by acid hydrolysis of natural cellulose
Chemical Properties
- Molecular structure: Linear polysaccharide composed of β-D-glucose units linked by β-1,4 glycosidic bonds
- Hydrolysis: Degraded into glucose under strong acid heating; resistant to weak acid and neutral aqueous environment
- Thermal stability: Stable below 200 °C; thermal decomposition and carbonization occur above 260 °C
- Hydrophilicity: Rich hydroxyl groups on molecular surface, good water absorption capacity
- Chemical inertness: No reaction with most pharmaceutical active ingredients, surfactants and cosmetic raw materials
- Compatibility: Compatible with all common excipients; incompatible with strong oxidants and concentrated hot alkali
3. Main Application Fields
1. Pharmaceutical Excipient (Core Application)
- Filler, binder and disintegrant for oral tablets, capsules and granules; improves molding hardness and quick disintegration
- Stabilizer for oral suspensions and topical creams to prevent ingredient sedimentation
2. Food Industry Additive
- Anti-caking agent, thickener and dietary fiber fortifier for baked food, dairy products and meat products
- Fat substitute for low-calorie food formulations
3. Cosmetic Raw Material
Matting powder, oil-absorbing agent and emulsion stabilizer for facial masks, cream, powder makeup and sunscreen
4. Chemical & Biochemical Auxiliary
- Adsorbent carrier for column chromatography separation
- Reinforcing filler for biodegradable polymer materials
