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, colour-carrier for dyestuffs and pigments, reinforcing filler for thermosetting resins and thermosetting laminates, coatings, emulsifiers, and also in water-based paints and ceramics industry.

Uses of Microcrystalline Cellulose.

The hydroxyl groups in cellulose macromolecules undergo esterification or etherification reactions to derive many useful products. The cellulose esters used in practice are: cellulose nitrate, cellulose acetate, cellulose acetate butyrate and cellulose flavate.

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

Microcrystalline cellulose can be applied to textile, clothing, brewing, food, paper making and other industries.

Pharmacological action 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.

The average cellulose content of our 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 materials obtained are called sulphite pulp and alkali pulp.

Then after bleaching to further remove residual lignin, the resulting bleached pulp can be used for paper production. The hemicellulose is further removed and can be used as a raw material for cellulose derivatives.
