MCC Microcrystalline Cellulose

 

The main component of MCC microcrystalline cellulose is β-1,4-glucose polymer, with a degree of polymerization of about 200-300 and a crystallinity of up to 60-80%, while ordinary cellulose is about 40%.

 

Preparation process:

 

• Raw materials: natural cellulose such as wood pulp and cotton lint.
• Hydrolysis: hydrochloric acid or sulfuric acid treatment to remove amorphous regions and retain crystalline regions.
• Mechanical crushing: spray drying or ball milling to produce 10-200 μm particles.

1. Physical and chemical properties

• High compressibility: tablet molding pressure only needs 50-100 MPa.
• Adsorption: specific surface area 5-10 m²/g, can load drugs or spices.
• Thermal stability: decomposition temperature 260-270℃, suitable for high temperature processing.

 

2. Biological properties

• Zero calories: not decomposed by human digestive enzymes, MCC microcrystalline cellulose is an insoluble dietary fiber.
• Prebiotic effect: promotes the proliferation of intestinal bifidobacteria.

 

 

1. Pharmaceutical field:
(1) Solid preparations

• Tablet excipients: account for 60-90%, improve hardness and disintegration.
• Controlled release carriers: regulate drug release rate through porosity.

 

(2) New drug delivery systems

• 3D printed tablets: compound hydrogel to achieve personalized dosage customization.
• Inhalation powder aerosol: MCC microcrystalline cellulose can enhance lung deposition rate.

 

2. Food industry:
(1) Functional additives

• Dietary fiber fortification: added to low-fat dairy products.
• Prevent moisture absorption: prevent powdered food from agglomerating.

 

(2) Innovative food development

• Plant-based imitation meat: compound pea protein to simulate meat fiber texture.
• Low-calorie baking: replace 30% wheat flour to reduce calorie intake.

 

3. Cosmetics and daily chemicals:
(1) Regulating skin feel

• Oil control powder: absorbs sebum, MCC microcrystalline cellulose used in loose powder and facial masks.
• Scrub particles: gently exfoliate.

 

(2) Enhanced stability
Emulsion suspension: prevents active ingredients from settling and prolongs shelf life.

 

4. Industry and environmental protection:
(1) Composite materials

• Bioplastics: blended with PLA to improve mechanical strength.
• Papermaking enhancer: add 1-2% to improve paper tear resistance.

 

(2) Environmental remediation
MCC microcrystalline cellulose has a lead ion adsorption capacity of 120 mg/g.
