Solubility: Soluble in water, not soluble in organic solvent

 

Main application:

CMC is called industrial MSG (Mono Sodium Glutamate), it’s widely used in many industries:

1), Detergent and personal care chemical industry

2), Food industry

3), Oil drilling

4), Textile, dyeing

5), Paper making

6), Mining

7), Porcelain

8), Construction

9), Pharmaceutical industry

 

Main types:

There are many types for different applications, it’s up to the following requests to define the type and grade:

1), Which industry: normally each industry has it’s own type CMC;

2), Raw material: CMC can be made from cotten, wasted cotten, wood, straw and even soybean curb residue;

3), Purity: From 55% to 99.5%;

4), Degree of substitution (D.S.): also called etherification degree, normal range is 0.4 to 1.2, higher D.S. Means higher solubility in water. For D.S.: 0.2~0.3, it is only soluble in alkali solution;

5), Viscosity: from 5~2500 m.Pas for 1% solution, some industries needs the data of 2% solution.

 

Function in detergent industry:

Due to the chemical and physical properties of CMC, it’s used as the suspending agent in detergent system and the flocculanting agent in water treatment applications. It can keep the dirt particles suspending in the solution, and prevent most dirt particles from becoming sediment on the fabrics again.

 

Function in food industry:

Thickener, suspending agent, stabilizer, film-forming agent, swelling agent and antistaling agent.

 

Max dosage in Food industry:

According to China’s national standard (GB2760-1996) and FAD/WHO (1984):

Beverage: 1.2g/kg max.

Instant noodle: 5.0g/kg max.

Can: 20.0g/kg max.

Instant soup: 4000mg/kg max.

 

Suggested application in Food industry:

Marshmallow: High molecular weight CMC, suggested D.S. is around 1.0;

Ice cream: Middle viscosity (250~260mPa.s), D.S 0.6, suggested dosage 0.4% max;

Beverage: High molecular weight CMC, suggested D.S. is around 0.6~0.8;

Instant noodle: Suggested dosage 0.1%;

Dehydrate vegetable: High molecular weight CMC, suggested D.S. 0.6;

Bread and frozen food: Mid viscosity CMC, suggested D.S. 0.5~0.8;

 

Important notice:

1), Incompatible conditions:

- Strong alkali solutions;

- Soluble metal salts;

- Organic solutions

 

2), Above suggested dosage and application is just for reference, for exact instruction, please refer to the related engineers and the local law and regulations of your area;

 

3), We normally list 2 years as the shelf life in our COA, the real shelf life is actually longer than 2 years if it’s stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials).
