Microcrystalline Cellulose Powder Usage and Synthesis.

Microcrystalline cellulose is mainly used as a non-caloric food additive, pharmaceutical excipient and dispersant, filler for thin-layer chromatography and column chromatography, color-carrying agent for dyestuffs and pigments, reinforcing filler for thermosetting resins and thermosetting laminates, coatings, emulsifiers, and also used in water-based paints and ceramics industry.

Uses of Microcrystalline Cellulose.

The hydroxyl groups in cellulose macromolecules undergo esterification or etherification reactions, which can lead to the derivation of many useful products. Practical application of cellulose esters are: cellulose nitrate, cellulose acetate, cellulose acetate butyrate and cellulose xanthate.

Cellulose ethers are: methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, cyanoethyl cellulose, hydroxypropyl cellulose and hydroxypropyl methyl cellulose. In addition, there are ester ether mixed derivatives.

As anti-caking agent, our country stipulates that it can be used in powder flavor, the maximum use amount is 50g/kg; it can also be used in ice cream, the maximum use amount is 40g.kg; it can also be used in thin cream and phytolipid powder, the maximum use amount is 20.0g/kg.

Pharmacological effect of Microcrystalline Cellulose.

Product Method of Bulk Microcrystalline Cellulose Powder.

Cellulose is the most abundant natural polymer compound in the world, and the raw materials for its production come from wood, cotton, cotton staple, wheat straw, rice straw, reeds, hemp, mulberry bark, kozo bark and bagasse. Due to the lack of forest resources in China, 70% of the raw materials of cellulose come from non-wood resources.

China's average cellulose content of coniferous and broadleaf timber is about 43-45%; the average cellulose content of grass stalks is about 40%. Cellulose industrial system is a sulfite solution or alkali solution cooking plant materials, mainly to remove lignin, respectively, known as sulfite method and alkali method. The material obtained is called sulfite pulp and alkali pulp.

Then after bleaching to further remove residual lignin, the resulting bleached pulp can be used for papermaking. Further removal of hemicellulose, can be used as raw materials for cellulose derivatives.
