What is Carboxymethylcellulose sodium salt?

1. Chemical properties and classification
Carboxymethylcellulose sodium salt， Commonly known as sodium carboxymethyl cellulose, it is a carboxymethyl derivative of cellulose and belongs to the ionic cellulose gel. Its molecular formula can be expressed as [C ₆ H ₇ O ₂ (OH) ₂ OCH ₂ COONa] ₙ, which is a linear water-soluble polymer compound. It is produced by the reaction of natural cellulose with caustic soda and chloroacetic acid, and is the most important ionic cellulose gel obtained by chemical modification of cellulose.

2. Physical characteristics and morphology
Carboxymethylcellulose sodium salt is a white to pale yellow fibrous, granular, or powdery substance that is odorless, tasteless, and hygroscopic. It is easily soluble in water and can form high viscosity transparent colloidal solutions under neutral or alkaline conditions, but insoluble in acids and alcohols.

The viscosity and solubility of aqueous solutions are closely related to the degree of substitution of carboxymethyl groups on their molecular chains. They are stable within the pH range of 2 to pH 10, precipitate below pH 2, and rapidly decrease in viscosity above pH 10. It is stable to heat and light, but its viscosity decreases when heated for a long time above 80 ℃. It turns brown when heated to 190-205 ℃ and carbonizes when heated to 235-248 ℃.

3. Preparation method and industry positioning
The preparation of Carboxymethylcellulose Sodium Salt adopts a two-step process. Firstly, there is the alkalization process of cellulose, which reacts with sodium hydroxide to produce alkali cellulose; Subsequently, alkali cellulose undergoes etherification reaction with chloroacetic acid, which is the classical Williamson ether synthesis method, ultimately producing carboxymethylcellulose sodium salt.

Industrial production can be classified into two types based on the etherification medium: aqueous media method and solvent medium method. Water-based methods are simple and inexpensive, but their product quality is low. They are therefore suitable for mid- to low-end products, such as textile sizing and detergents.
As a widely used fine chemical product, Carboxymethylcellulose sodium salt occupies an important position in various industrial fields such as food, medicine, daily chemical, petroleum, papermaking, and textiles.

Application of Carboxymethylcellulose sodium salt

Carboxymethylcellulose sodium salt, as an excellent water-soluble polymer compound, has multiple functions such as thickening, emulsification, stability, film-forming, and water retention

1. Food Industry

In the food industry, carboxymethylcellulose sodium salt is an ideal thickener, emulsifying stabilizer, and water retaining agent. It can be used to improve the taste of acidic dairy drinks, prevent casein from precipitating and aggregating under low pH conditions and stabilize the protein system. Adding 0.4% -0.5% carboxymethylcellulose sodium salt to stirred yogurt can significantly enhance system stability and prevent whey precipitation.

It can be used to soften the taste of flour products like bread or Mantou. This will also delay the ageing and retrogradation and prolong the shelf-life. In addition to its gel function, it can also be used for the production of jam, jelly and other products. Its film-forming qualities make it a suitable edible coating material for fruits and vegetables preservation. It extends the shelf life of fruits and veggies by creating a microenvironment with low oxygen and high CO2.

2. Chemical and washing industry

In the field of detergents, the primary use of Carboxymethylcellulose sodium salt is in the formulation of soap and synthetic detergents. Adding about 1% carboxymethylcellulose sodium salt to the heavy scale cleaner can effectively prevent the washed out dirt from depositing on the fabric surface again, exerting an anti re deposition effect. It is used as a colloidal tackifier in cosmetics and personal-care products. Its mild, non-irritating properties make it a great excipient for daily chemical formulas.

3. Petroleum and Industrial Applications

In the petroleum industry, carboxymethylcellulose sodium salt is an important suspension stabilizer for drilling mud. The high viscosity of the carboxymethylcellulose sodium salt and its excellent suspension properties can be used to carry rock debris and balance formation pressure. It also protects wellbore walls. It can be used in the paper industry as a pulp add-on to improve the longitudinal strength, smoothness, and printing adaptability of paper. It is used in the textile industry as a thickener and sizing agent for printing and dyeing to improve fabric processing. It is also used in ceramics as an adhesive, thickener and to help shape the body of the product and disperse glaze evenly.

4. Medical and environmental protection

In the pharmaceutical industry, carboxymethylcellulose sodium salt can be used as an emulsifying stabilizer for injections, a binder for tablets, and a film-forming agent. The good biocompatibility of the carboxymethylcellulose sodium salt makes it suitable for medical materials, such as soluble bands that can reduce pain when removing bandages. It is used in water treatment as a flocculant. This is mainly for wastewater treatment and sludge. It can increase the solid content and dewatering of the filter cake. It can be used in agriculture to make pesticide formulations and improve adhesion.
