Oil Drilling Chemicals Drilling Fluid Additives Sodium Carboxymethyl Cellulose CMC Powder Price

Carboxymethylcellulose (CMC) is a nontoxic and tasteless white flocculent powder with stable performance and is easy to dissolve in water. Sodium carboxymethylcellulose (CMC), commonly known as "industrial monosodium glutamate", is the most widely used and convenient product among cellulose ethers.
CMC can be used as binder, thickener, suspending agent, emulsifier, dispersant, stabilizer, sizing agent, etc.

Carboxymethyl cellulose (CMC) is an anionic cellulose ether, the appearance is white or slightly yellow flocculent fiber powder or white powder, odorless, tasteless, non-toxic; Easily soluble in water, forming a transparent solution with a certain viscosity. The solution is neutral or slightly alkaline, insoluble in ethanol, ether, isopropyl alcohol, acetone and other organic solvents, but soluble in ethanol or acetone solution with 60% water content. It is hygroscopic, stable to light and heat, and the viscosity decreases with the increase of temperature.

Features:
1. Almost odorless, odorless, and hygroscopic.
2. Easy to disperse in water into a transparent colloidal solution, insoluble in organic solvents such as ethanol.
3. The pH of the 3.1% aqueous solution is 6.5-8.5. When pH>10 or<5, the viscosity of the adhesive significantly decreases, and the performance is best at pH=7.
4. It is thermally stable, with a rapid increase in viscosity below 20 ℃ and a slower change at 45 ℃. Prolonged heating above 80 ℃ can cause colloid denaturation while significantly reducing viscosity and performance.
5. Easy to dissolve in water, transparent solution;

Grade of CMC:
Food Grade CMC
Detergent Grade CMC
Oil Drilling Grade CMC
Ceramics Grade CMC
Paint Grade CMC
Textile and Dyeing Grade CMC

CMC is not only a good emulsifying stabilizer and thickener in food application, but also has excellent freezing and melting

stability, and can improve the flavor of products and prolong the storage time。

In soy milk, ice cream, ice cream, jelly, beverage, canned consumption is about 1% ~ 1.5%. CMC can also be used with vinegar, soy sauce, vegetable oil, fruit juice, meat juice, vegetable juice and other stable emulsifying dispersion, the dosage is 0.2% ~ 0.5%.

Especially for animal, vegetable oil, protein and aqueous solution emulsification performance is extremely excellent, can make it form stable homogeneous emulsion.

As it is safe and reliable, its dosage is not restricted by the food hygiene standard ADI.

Function of CMC in food production：

1.thickening: viscosity at low concentration. It can control the viscosity in the process of food processing and give food a sense of lubrication;

2.water retention: reduce the dehydration contraction of food, prolong the shelf life of food;

3.dispersion stability: to maintain the stability of food quality, prevent oil and water stratification (emulsification), control

the size of crystals in frozen food (reduce ice crystals);

4.film forming: in fried food to form a layer of film, prevent excessive absorption of oil;

5.Chemical stability: stable to chemicals, heat and light, with certain mildew resistance;

6.metabolic inertia: as a food additive, will not be metabolized, in the food does not provide calories.

As a thickener and stabilizer for acidic dairy products, CMC prevents the protein in the dairy products from coagulating,

precipitating and layering, makes the dairy products a unique and delicate taste.

As a water-retaining agent for pastries and jam fillings, CMC prevents food dehydration, imparts certain thixotropy, improves storage stability, improves the gloss of pastries and prevents cracking.

CMC can be used as paper sizing agent in paper making industry, in the ceramic industry as excipient of billet, plasticizer,strengthening agent, used as a sizingagent in textile industry, the cosmetics as hydrosol, as resistance to dirt redeposition

agent in detergent, in oil drilling mud can be used to protect the well as stabilizing agent, water retention agent, used as athickener in the toothpaste, etc.
