Microcrystalline cellulose is a kind of purification, part of the cellulose depolymerization, white, odorless, tasteless, a porous crystalline powder composed of particles. Microcrystalline cellulose is widely used in pharmaceutical, cosmetic and food industries, different particle size and water content have different characteristics and application scope. 

Storage methods: outer lining sack packing plastic bags. Store in a cool and dry place, avoid high humidity and high temperature. 

Main use: this product can be used for the anticaking agent, emulsifier, dispersant, binder, pressure improver, tablet and group. Can also be used to heat stabilizer and the carrier of rapid drying. Also can be used as dietary fiber is applied to low calorie and low fat, and other special nutritional food. 2. It has three effects, whitening color, soft fabric, to remove dirt particles, properties of cellulose fibers, such as cotton and cotton blended products effectively 

Properties and stability: 1. Under the atmospheric pressure is stable and can be compressed into sheets, can disperse in water, but water swelling. 

2. Avoid light, open flame, high temperature, 

This strain cotton fiber via hydrolysis of powder, calculated on dry goods, fiber should be 97.0% ~ 102.0%. 

Content: 

Take this product is about 0.125 g, precision said, conical flask, 25 ml of water, precision compound potassium chromate solution (benchmark 4.903 g potassium dichromate, add water right amount to dissolve and diluted to 200 ml) of 50 ml, blending, careful to add 100 ml of sulfuric acid rapidly heated to boiling, let cool to room temperature, move into 250 ml volumetric flask and thin up to scale, shake well, precision measuring 50 ml, plus adjacent two nitrogen fe 3 drops indicating liquid, liquid with ammonium ferrous sulfate titration titration (0.1 mol/L), and the result of the titration correction by blank test. Each 1 ml ammonium ferrous sulfate volumetric solution (0.1 mol/L) is equivalent to 0.675 mg of cellulose. 

category Excipients. 

Method: 

The method name: microcrystalline cellulose - - REDOX titration method for determination of the cellulose 

Application: this method USES the titration method for determining the content of cellulose in microcrystalline cellulose. 

This method is suitable for microcrystalline cellulose. 

Greatly method principle: the conical flask, 25 ml of water, precision increase potassium chromate solution 50 ml, blending, carefully add 100 ml sulfate rapidly heated to boiling, let cool to room temperature, move into 250 ml volumetric flask and thin up to scale, shake well, precision measuring 50 ml, plus adjacent two nitrogen fe 3 drops indicating liquid, liquid with ammonium ferrous sulfate titration titration (0.1 mol/L), calculate the content of cellulose.
