What is the difference between microcrystalline cellulose and cellulose?
Abstract. Microcrystalline cellulose (MCC) is a pure partially depolymerized cellulose synthesized from α-cellulose precursor (type Iβ), obtained as a pulp from fibrous plant material, with mineral acids using hydrochloric acid to reduce the degree of polymerization.

How to manufacture microcrystalline cellulose?
Microcrystalline cellulose is produced by subjecting to a high shear treatment, at elevated temperature and pressure, a reaction mixture of a cellulose material, an active oxygen compound and water, for a time effective to depolymerize the cellulose material.
What is degree of polymerization of cellulose?
The degree of polymerization of cellulose is calculated from the intrinsic viscosity of solutions prepared by dissolving cellulose in a suitable solvent, such as CED or cadoxen.
How does condensation polymerisation work?
Some polymers are made via condensation polymerisation . In condensation polymerisation, a small molecule is formed as a by-product each time a bond is formed between two monomers . This small molecule is often water. An example of a condensation polymer is nylon.
What does microcrystalline cellulose do to the body?
Microcrystalline cellulose (C6H10O5)n is refined wood pulp. It is a white, free-flowing powder. Chemically, it is an inert substance, is not degraded during digestion and has no appreciable absorption. In large quantities it provides dietary bulk and may lead to a laxative effect.
What is the purpose of microcrystalline cellulose?
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.
What is microcrystalline cellulose good for?
How do you dissolve microcrystalline cellulose?
Discussion. Micro-crystalline cellulose can be dissolved in NaOH/water with 7–10% of NaOH below 0 °C. DSC experiments reveal that the addition of Avicel cellulose does not change either the temperature of the NaOH eutectic mixture or the temperature of melting ice.
Is microcrystalline cellulose harmful?
According to the Select Committee on GRAS Substances, microcrystalline cellulose is generally regarded as safe when used in normal quantities.
