    Product Description

    Microcrystalline Cellulose, CAS 9004-34-6, commonly abbreviated MCC, is a purified, partially depolymerized cellulose supplied as a pharmaceutical, food and cosmetic excipient; the EC/EINECS number is 232-674-9.

    Synonyms: MCC; Cellulose microcrystalline; Purified cellulose; Hydrolyzed cellulose; Cellulose powder.

    CAS: 9004-34-6.

    Molecular formula: (C₆H₁₀O₅)ₙ.

    EC number: 232-674-9.

    It is a white to off-white, odorless, free-flowing powder; the bulk density is about 0.26–0.35 g/cm³ depending on grade.

    It is practically insoluble in water and most organic solvents; a 1% suspension has a pH of about 4.0–6.0.

    It is produced by controlled hydrolysis of alpha-cellulose from fibrous plant material.

    It is used as a direct-compression binder, filler, diluent, disintegrant and flow aid in tablets and capsules.

    It is also used as an anti-caking agent and stabilizer in food, dietary supplements and cosmetics.

    It differs from ordinary cellulose powder or powdered cellulose by its higher purity, partial depolymerization and better direct-compression performance.

    Common grade choices include finer PH-101, larger-particle PH-102 and free-flowing PH-200 type grades, plus co-processed or agglomerated grades.

    Confirm average particle size, bulk and tapped density, moisture, degree of polymerization and the required pharmacopoeial or food grade.

    Store tightly closed in a cool, dry area away from moisture, strong oxidizers and excessive heat; use dust controls and suitable PPE because it is a combustible organic powder.

    Confirm the current product-specific specification.

    Confirm packaging with the requested quantity and destination requirements.

    Document requirements should be confirmed from the current specification, SDS, COA or other product-specific files.

    FAQ - Technical & Supply Chain

    • Q:

      What is Microcrystalline Cellulose CAS 9004-34-6?

      A: Microcrystalline cellulose, or MCC, is a purified, partially depolymerized cellulose made by controlled hydrolysis of alpha-cellulose from fibrous plant material. Its general formula is (C₆H₁₀O₅)ₙ and it is supplied as a white to off-white, odorless powder.
    • Q:

      What is Microcrystalline Cellulose used for in pharmaceuticals?

      A: MCC is used as a direct-compression binder, filler, diluent, disintegrant and flow aid in tablets and capsules. It is especially valued for its compressibility, compactibility and compatibility with many active ingredients.
    • Q:

      Is Microcrystalline Cellulose the same as cellulose powder?

      A: Not exactly. Both are cellulose-based powders, but microcrystalline cellulose is more purified and partially depolymerized, with better tablet-compression and direct-compression performance than ordinary cellulose powder or powdered cellulose.
    • Q:

      What MCC grades should be considered for formulation?

      A: Common choices include finer PH-101, larger-particle PH-102 and free-flowing PH-200 type grades, plus co-processed or agglomerated grades. Confirm average particle size, bulk and tapped density, moisture, degree of polymerization and the required pharmacopoeial or food grade.
    • Q:

      How should pharmaceutical-grade Microcrystalline Cellulose be stored and handled?

      A: Store it tightly closed in a cool, dry area away from moisture, strong oxidizers and excessive heat. Use dust controls and suitable PPE because it is a combustible organic powder.
