Microcrystalline Cellulose 101

Back to Excipients Page

Microcrystalline cellulose (MCC) is a term for refined wood pulp and is used as a texturizer, an anti-caking agent, a fat substitute, an emulsifier, an extender, and a bulking agent in food production. The most common form is used in vitamin supplements or tablets. Material meets BP- 2018 specifications

Usage and Applications:
  • Microcrystalline Cellulose is a versatile product and used in pharmaceutical formulations as Excipient.
  • MCC is also used in food industries as an anti-caking agent and a bulking agent.
  • Microcrystalline Cellulose is derived from Wood pulp and the most common form is used in vitamin supplements or tablets.
  • MCC 101- most suitable for wet granulation and direct compression.
  • MCC 102- particle larger than 101 good flow and high compatibility , suitable for direct compression activity.
  • MCC 103-same as grade 101 but with low moisture content for processing water sensitive actives.
  • MCC 105-It has the finest particle size and may be used in direct compression of coarser , granular and crystalline materials.
  • MCC 112-Same as grade 102 but with low moisture content for processing water sensitive actives.
  • MCC 200-It has a large particle size which offers increase flow ability with minimum effect on compression characteristics.
  • MCC 301-same as grade 101but with higher bulk density & improved flow properties.
  • MCC 302-same as grade 102but with increased bulk density & increased flow properties. Suitable for high speed tableting and potential for smaller tablet.
