Carboxymethylcellulose calcium (nf) - Physico-chemical Properties
| Molecular Formula | C23H30ClN3O |
| Molar Mass | 399.9568 |
| Solubility | Practically insoluble in acetone, chloroform, ethanol(95%), toluene, and ether. Insoluble in water, but swells to forma suspension. |
| Appearance | White to light yellow solid |
| Storage Condition | 室温,密封 |
| Physical and Chemical Properties | White to yellowish powder or fibrous. No smell. It is stable to heat, light, air, microorganisms, etc. A few are insoluble in water. In order to improve taste, it is often processed into fine powder below 200 mesh. Water absorption is swollen several times. The pH value of 1g/20ml suspension in water is 4.5~6.0, which has weak binding when acidic and strong binding when alkaline, and loses collapsibility. |
| Use | Can be used for soup powder molding, dissolved due to water swelling characteristics, promote the collapse and dispersion. For solid and powdered foods such as cocoa powder, instant coffee, and powder cool drinks, it has the effect of promoting dispersion and dissolution in water. |

Carboxymethylcellulose calcium (nf) - Introduction
Carboxymethylcellulose calcium is also known as sodium calcium carboxymethyl cellulose, which is an inorganic salt with the chemical formula C6H7O6COONaCa. It has the following properties:
1. Physical properties: Carboxymethylcellulose carbonate is a white to yellowish white powder, tasteless and odorless.
2. Solubility: insoluble in water, but can be dissolved in acidic solution.
3. Viscosity: Carboxymethylcellulose cellulose has high viscosity and is often used as a thickener and adhesive.
4. Stability: It has good thermal stability and chemical stability, and can maintain its properties under high temperature and acidic conditions.
Carboxymethylcellulose calcium is mainly used in the following aspects:
1. In the field of medicine: Carboxymethylcellulose calcium is commonly used as a coating agent for capsules and tablets, which can protect drugs from being damaged by moisture and light and prolong the shelf life of drugs.
2. Food industry: it can be used as thickener, stabilizer and emulsifier, commonly used in dairy products, fruit juice, biscuits and other foods.
3. Cosmetics: Carboxymethylcellulose calcium has good moisturizing properties and is widely used in cosmetics, such as creams, Essence, etc.
in terms of preparation method, carboxymethylcellose calcium is firstly prepared by alkaline hydrolysis reaction of cellulose, and then reacted with calcium carbonate to prepare carboxymethylcellose calcium.
Regarding safety information, Carboxymethylcellulose calcium is generally considered harmless, but the following points should be noted when using it:
1. Avoid direct contact with skin and eyes, such as contact, should immediately rinse with water.
2. Store to keep dry, avoid mixing with acidic substances.
3. Follow the correct usage and method, and strictly follow the product instructions.
Overall, Carboxymethylcellulose calcium is a multifunctional compound widely used in the fields of medicine, food and cosmetics. However, please read the product manual carefully before use and follow the relevant safety operation specifications.
