Microcrystalline Cellulose PH 102

Product Overview

Microcrystalline Cellulose PH 102 is a high-purity pharmaceutical-grade excipient derived from purified cellulose and widely used in solid oral dosage formulations.

Compared with finer-particle MCC grades such as PH 101, PH 102 has a relatively coarser particle-size distribution. This physical characteristic generally provides improved powder-flow properties while retaining the characteristic compressibility and binding functionality of Microcrystalline Cellulose.

PH 102 is particularly useful in pharmaceutical manufacturing processes where powder handling, flowability, die filling and production consistency are important considerations.

Key Characteristics

  • Pharmaceutical-grade Microcrystalline Cellulose
  • Relatively coarse particle-size distribution
  • Generally improved flowability compared with finer MCC grades
  • Good to excellent compactibility
  • Effective binding functionality
  • Suitable for direct compression
  • Favorable powder-handling characteristics
  • Suitable for high-throughput tablet manufacturing
  • White, odorless and chemically stable powder

Functional Properties

Improved Powder Flow

The relatively larger particle size of PH 102 generally provides improved powder-flow characteristics compared with finer MCC grades.

Improved flow can facilitate powder movement through feeders and hoppers and support more consistent die filling during tablet manufacturing.

 

 

Compressibility

PH 102 retains the characteristic compressibility of Microcrystalline Cellulose and can form strong, coherent tablets under appropriate compression conditions.

Binding Function

PH 102 provides effective binding functionality and can contribute to tablet mechanical integrity when incorporated appropriately into a formulation.

Diluent / Filler Function

PH 102 can function as a multifunctional diluent and filler in solid oral dosage formulations, providing both bulk and functional compression properties.

Pharmaceutical Applications

Microcrystalline Cellulose PH 102 can be used in:

  • Direct-compression tablets
  • Immediate-release tablets
  • Conventional compressed tablets
  • Capsule formulations
  • High-throughput tablet manufacturing
  • Solid oral dosage formulations
  • Formulations requiring improved powder-flow characteristics
  • Formulations requiring a balance between flowability and compactibility

Direct Compression

PH 102 is widely suitable for direct-compression applications because its relatively coarse particle structure can provide favorable powder-flow characteristics while maintaining good compressibility.

Improved powder flow can support more consistent die filling and powder feeding, which are important considerations in high-speed tablet production.

The final suitability of PH 102 depends on the complete formulation, including API properties, other excipients, compression parameters, tooling and manufacturing equipment.

Particle Size and Its Importance

The particle-size distribution of PH 102 is generally coarser than that of PH 101.

This characteristic can influence:

  • Powder flow
  • Die filling
  • Powder feeding
  • Handling characteristics
  • Processing efficiency
  • Manufacturing consistency

Particle size should not be evaluated independently. Powder flow and compression behavior can also be influenced by particle morphology, moisture content, bulk density, formulation composition and processing conditions.

Tablet Manufacturing Performance

PH 102 can support:

  • Consistent powder feeding
  • Improved die filling
  • Uniform tablet weight
  • Efficient high-speed processing
  • Good compactibility
  • Adequate tablet mechanical strength
  • Consistent manufacturing performance

Actual tablet weight variation, hardness, friability, disintegration and dissolution depend on the complete formulation and manufacturing process.

High-Speed Manufacturing

A key advantage of PH 102 is its favorable flow behavior in manufacturing environments where efficient powder handling is important.

Its relatively coarse particle structure can facilitate powder movement through manufacturing equipment and support consistent die filling during high-speed compression.

This makes PH 102 a practical choice for large-scale tablet manufacturing where powder flow and processing efficiency are important formulation considerations.

Formulation Considerations

PH 102 may be particularly appropriate when a formulation requires:

  • Improved powder flow
  • Reliable powder feeding
  • Consistent die filling
  • Direct-compression capability
  • A balance between flowability and compactibility
  • Efficient high-throughput manufacturing

Quality and Regulatory Considerations

For pharmaceutical applications, Microcrystalline Cellulose PH 102 should comply with the applicable pharmaceutical specification and relevant pharmacopoeial or customer requirements.

Typical quality-control parameters may include:

  • Identification
  • Cellulose content / assay
  • Loss on drying
  • Residue on ignition
  • pH
  • Water-soluble substances
  • Ether-soluble substances
  • Elemental impurities, where applicable
  • Microbial quality
  • Particle-size distribution
  • Bulk density
  • Other customer-specific requirements

The final product specification should be established according to the applicable pharmacopoeial requirements and the manufacturer's approved technical specification.

Storage and Handling

Store in tightly closed packaging in a clean, dry and well-ventilated environment. Protect the material from excessive moisture, direct sunlight and contamination.

Specific storage conditions, shelf life and packaging requirements should be defined according to the approved product specification and technical documentation.
