CAS 9004-32-4 Sodium Carboxy Methyl Cellulose Sodium CMC Sodium Carboxymethyl Cellulose

Product Description

Sodium carboxymethyl cellulose (CMC) is a versatile and widely used cellulose derivative. 

Description:
Sodium carboxymethyl cellulose is derived from cellulose, a natural polymer found in plant cell walls. It is produced by chemically modifying cellulose through the introduction of carboxymethyl groups. CMC is available as a white to off-white powder or granules, and its properties can vary depending on the degree of substitution and molecular weight.

Technical Data Sheet:
As an AI language model, I don't have real-time access to specific technical data sheets. However, here are some general properties of sodium carboxymethyl cellulose:

Chemical Formula: [C6H7O2(OH)2CH2COONa]n
CAS Number: 9004-32-4
Appearance: White to off-white powder or granules
Solubility: Soluble in water
pH (1% solution): Typically between 6.0 and 8.5
Viscosity: Varies depending on the grade and concentration

Features:

1. Water Solubility: Sodium carboxymethyl cellulose is highly soluble in water, forming clear or slightly opaque solutions. It can exhibit pseudoplastic or thixotropic behavior, meaning its viscosity decreases under shear stress.
2. Thickening and Stabilizing Agent: CMC is an effective thickener and stabilizer in various applications. It imparts viscosity and improves the texture, stability, and mouthfeel of liquid and semi-solid formulations.
3. Film-Forming Properties: CMC can form films that are flexible, transparent, and resistant to oil and grease. These films find applications in coatings, adhesives, and edible films for food products.
4. Pseudoplastic Behavior: CMC shows a shear-thinning behavior, meaning its viscosity decreases as shear rate or agitation increases. This property allows for easier processing and application in various systems.
5. Compatibility: Sodium carboxymethyl cellulose is compatible with many other ingredients, including salts, surfactants, and other polymers. It can be used in combination with other additives to achieve desired functionalities.

Applications:
Sodium carboxymethyl cellulose finds applications in various industries due to its versatile properties. Some common applications include:

1. Food Industry: CMC is used as a thickener, stabilizer, and texturizer in a wide range of food products, including sauces, dressings, dairy products, baked goods, beverages, and confectionery. It helps improve texture, prevent syneresis, and enhance mouthfeel.
2. Pharmaceutical Industry: CMC is utilized as a binder, disintegrant, and suspending agent in pharmaceutical formulations, such as tablets, capsules, creams, and suspensions. It aids in the controlled release of drugs and improves formulation stability.
3. Personal Care Products: CMC is employed in personal care products, including toothpaste, shampoo, lotion, and creams, as a thickener, stabilizer, and film-forming agent. It enhances product texture, provides rheological control, and contributes to long-lasting effects.
4. Paper and Packaging: CMC is used in the paper industry as a coating agent, binder, and film former. It improves paper strength, printability, and water resistance. In packaging, CMC can provide adhesion, moisture retention, and film-forming properties.
5. Textile and Detergent Industry: CMC is utilized in textile printing and dyeing processes as a thickener and binder. In detergents, it acts as a soil suspension agent, preventing redeposition of dirt on fabrics during washing.
