Sodium carboxymethylcellulose (or cmc, carboxymethylcellulose, cellulose gum, sodium cmc, cellulose sodium, carboxymethylcellulose sodium salt), is now a kind of cellulose with the widest range of application and the maximum usage amount. Sodium carboxymethylcellulose is the sodium salt of cellulous carboxymethyl ether and belongs to anionic cellulose ethers, in shape of white or light yellow powder.
There are more and more approaches to application of sodium carboxymethylcellulose in food production and different properties play different roles. Now, it has been widely used in various food industries such as cold drinks, frozen food, dairy products and fruit juice.
Sodium carboxymethyl cellulose (CMC) has a variety of functions in foods such as thickening, suspension, emulsification, stabilization, shape retention, film formation, expansion, preservation, acid resistance and health care. It can replace guar gum, gelatin, The role of agar, sodium alginate and pectin in food production is widely used in modern food industry, such as lactobacillus drinks, fruit milk, ice cream, sherbet, gelatin, soft candy, jelly, bread, fillings, pancakes , Cold products, solid beverages, condiments, biscuits, instant noodles, meat products, paste, biscuits, gluten-free bread, gluten-free pasta, etc. Used in food, it can improve the taste, improve the grade and quality of the product, and extend the shelf life.
For Food industry:
Food grade for dairy drinks and seasonings, CMC can thicken, stabilize and improve taste. In addition, CMC is also used in ice cream, bread, cake, biscuit, instant noodle and fast paste food for product molding, taste improvement, water retaining and tenacity strengthening.
For Detergent Industry:
Effectively prevent washes from becoming contaminated after being washed by synthetic detergent. Also make washing liquid more viscous and the effect of washing more stable
Hydroxypropyl methyl cellulose
Hs code:3912, 900
Cas:9004-65-3
Hydroxypropyl methyl cellulose is a kind of white or slightly yellowish powder, odorless, tasteless, and non-toxic. The product can be dissolved in cold water to form a transparent viscous solution. The aqueous solution of this product has surface activity so that it has emulsification, protective colloids and relative stability. Ph stability: the aqueous solution viscosity of this product is relatively stable in the range of ph 3.0â??11.0. As the product is non-ionic, and in the preparation process can be effectively purified by washing with hot water, it has a very low ash content. Hydroxypropyl methylcellulose products can fully meet the standards for use of medicine, food, construction and personal care products.

HydroxyEthy Cellulose (HEC for short) is a non-ionic soluble cellulose ether, both soluble in cold and hot water, with thickening, suspension, adhesion, emulsification, film-formation, water retention, protective colloids and other properties, widely used in coatings, cosmetics, oil drilling and other industries.
Dissolve Hydroxyethy Cellulose in water
Retarded Hydroxyethy Cellulose can be directly added into paint formulation, will form homogeneous, glazed solution. Period from powder wetted till dissolution completed call hydration time. During this process, solution build up thickening ability.
Temperature and PH has effect on hydration time. Increase PH to 8.0-10.0, will shorten the time 40-60%; temperature increase will shorten this time as well.
Normally, we suggest to add Hydroxyethy Cellulose at room temperature and neutural situation, hydration time is around 25 minutes.
Application Guide for Paint Industry
High Thickening Effects
SidleyCel Hydroxyethy Cellulose provides the latex paints especially high PVA paints with excellent coating performance. When the paint is thick paste, no flocculation will occur.
SidleyCel Hydroxyethy Cellulose has higher thickening effects, so can reduce the dosage, improve the cost-effectiveness of formulation, and enhance the washing resistance of paints.
Excellent Rheological Properties
The aqueous solution of SidleyCel Hydroxyethy Cellulose is a non-Newtonian system, and the properties of the solution are called thixotropy.
In the stationary state, after the product is completely dissolved, the coating system can maintain the best thickening condition and can-opening state.
In the dumping state, the system can keep a moderate viscosity, making products with excellent fluidity, and not spatter.
During brushing and roller coating, the product is easy to spread on the substrate, so convenient for construction, and meanwhile, has good spatter resistance.
Finally, after the coating of paint is completed, the viscosity of the system will immediately get restored, and the paint will immediately produce sagging property.
Dispersion and Solubility
SidleyCel Hydroxyethy Cellulose is all treated by the delayed dissolution, and in the case of adding dry powder, can effectively prevent caking and make sure hydration starts after the adequate dispersion of HEC powder.
The SidleyCel Hydroxyethy Cellulose after a proper surface treatment can well regulate the dissolution rate and viscosity increase rate of the product.
Storage Stability
SidleyCel Hydroxyethy Cellulose has good mildew-resistant performance, provides enough storage time for paints, and effectively prevent settlement of pigments and fillers.

What is Carboxymethylcellulose sodium?
Carboxymethyl cellulose (CMC) or cellulose gum is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used as its sodium salt, sodium carboxymethyl cellulose.
CMC is used in food under the E number E466 as a viscosity modifier or thickener, and to stabilize emulsions in various products including ice cream. It is also a constituent of many non-food products, such as toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing, and various paper products.
