CMC Use The Widest Range
Aug 29, 2017

CMC Use the widest range

Sodium carboxymethyl cellulose (CMC) is the largest and most widely used cellulose, so its price has been a concern of users. So, what are the main factors influencing the price? Why are the prices of each manufacturer different?

As we all know, the main indicator of the quality of sodium carboxymethyl cellulose is the substitution degree (DS) and purity. The properties of sodium carboxymethyl cellulose are also different in general. The greater the substitution, the better the solubility, the better the transparency and stability of the solution, the difference between the natural prices of products with different degrees of substitution and purity.

According to the use of sodium carboxymethyl cellulose, it can be divided into adhesion, thickening, emulsification, water retention, anti - precipitation, skeletal enhancement and so on.

Many factors affect the performance of sodium carboxymethyl cellulose, has the characteristics of raw material sources, average molecular weight, size distribution curve, carboxymethylated proportion, carboxymethylated uniformity, salt residues, powder particle size, filler properties and so on, these can all be factors that affect the price.

Different industries, such as oil drilling platforms, require CMC anti-precipitation, and can not have high viscosity. The toothpaste USES CMC to thicken, so the viscosity is high.

To sum up, different industries have different performance requirements for sodium carboxymethyl cellulose, so its price will show different differences. In addition to the quality of the purchase, you should choose according to the requirements of the industry, and cannot consider the price factor unilaterally. Sodium carboxymethyl cellulose as the sodium salt of carboxymethyl cellulose ether, anionic cellulose ether, is white or milk white fibrous powder or particles, the density of 0.5-0.7 / c ㎡, several odourless, tasteless, hygroscopicity. It is easy to disperse in water to become clear gelatinous liquid, in organic solvent such as ethanol insoluble. For its efficacy and purpose, the following are detailed.

Sodium carboxymethyl cellulose has the function of adhesion, thickening, enhancement, emulsification, water retention and suspension.

1, the application of sodium carboxymethyl cellulose in the food industry: sodium carboxymethyl cellulose in food applications is not only a good emulsifying stabilizer, thickener, and excellent stability of freezing and melting, and can improve the flavor of the product, extend the storage time.
