Project Description
Product Description
Sodium carboxymethyl cellulose(CMC) is the most widely used and the largest amount of cellulose in the world today. It is white fibrous or granular powder. Odorless, tasteless, tasteless, hygroscopic, insoluble in organic solvents.
The properties of sodium carboxymethyl cellulose are as follows:
Moisture absorption characteristics, the degree of moisture absorption is related to atmospheric temperature and relative humidity, when it reaches equilibrium, it will no longer absorb moisture.
CMC water solution has excellent properties such as adhesion, thickening, emulsification, suspension, film formation, protective colloid, moisture retention, resistance to enzymatic hydrolysis, and metabolic inertia.
When CMC aqueous solution meets tin, silver, aluminum-lead, iron, copper and some heavy metals, precipitation reaction will occur; when CMC aqueous solution coexists with calcium, magnesium, and salt, precipitation will not occur, but the viscosity of CMC aqueous solution will be reduced. When the CMC aqueous solution encounters acid, an acidic CMC precipitate will precipitate. But acid-resistant CMC has certain resistance to acid solutions.
Application
- CMC has the characteristics of thickening, emulsification, shaping, water retention and stability. Adding CMC to food can reduce the production cost of food, improve food grade, improve food taste, and extend the shelf life of food. It is an ideal food additive for the food industry and can be widely used in various solid and liquid beverages, cans, and candies. , Cakes, meat products, biscuits, instant noodles, rolled noodles, quick-cooked foods, quick-frozen flavored snack foods and soy milk, yogurt, peanut milk, fruit tea, fruit juice and other food production. In different foods, CMC has different uses and dosages.
- CMC can be used as an emulsion stabilizer for injections, a binder and film-forming agent for tablets in the pharmaceutical industry.
- CMC can be used as a binding agent and anti-resettling agent in the daily chemical industry.
- CMC is used as a paper sizing agent in the paper industry, which can significantly improve the dry and wet strength, oil resistance, ink absorption and water resistance of paper.
- It can be used as a component of oil fracturing fluid in petrochemical industry.
- CMC is used as a hydrosol in cosmetics and as a thickener in toothpaste, and its dosage is about 5%.
