It is often referred to as medium viscosity food-grade sodium carboxymethylcellulose and functions as a versatile thickener, binder, and suspending agent in a wide range of applications. It has eco-friendly credentials, being harmless to the environment. CMC powder stands as a professional and indispensable ingredient.

What Does CMC Powder Stand For?

CMC powder is an abbreviation for Carboxymethyl Cellulose. This fine, white powder is known for its unique properties. While CMC powder is its most recognized name, you may encounter CMC powder referred to as “tylose powder” or “tylo powder.” These alternative names are essentially interchangeable with CMC powder and are used to describe the same substance with its distinctive properties.

Properties and Application: CMC Powder

As mentioned above, CMC is widely used as an additive in a lot of industries. It possesses unique and great characteristics that enables manufacturers formulate their products. Here are few of the Carboxymethylcellulose ’s characteristics:

CAS No.

The CAS number of Carboxymethylcellulose is the number 9004-32-4 is the key to distinguishing and cataloging this compound in scientific databases and industry documentation. It has the ability to alter the viscosity of solutions effectively. CMC powder, when added to a solution, significantly increases its viscosity. This property makes it invaluable in various applications.

Molecular Formula

At the heart of understanding Carboxymethyl Cellulose (CMC) powder lies its intricate chemical composition, represented by the formula [C6H7O2(OH) x(OCH2COONa) y] n. The variable ‘n’ signifies the degree of polymerization, indicating the number of repeating units in the CMC polymer chain. It reflects the length of the molecular structure, influencing the compound’s physical properties and functionality.

The variables ‘x’ and ‘y’ denote the degree of substitution in CMC. ‘x’ represents the substitution of hydroxyl (OH) groups in cellulose, typically falling within the range of 1.50 to 2.80. Meanwhile, ‘y’ signifies the substitution of sodium carboxymethyl (OCH2COONa) groups, typically ranging from 0.2 to 1.50. The sum of ‘x’ and ‘y’ equals 3.0, highlighting the balance between these two types of substitutions.

Specifications

CMC powder is known for as a powder with an appearance ranging from white to off-white. The particle size of CMC powder is a crucial parameter that impacts its performance in various applications. The specification that 95% of the particles pass through an 80-mesh sieve highlights its fine granular nature. The pH value of CMC powder is maintained within a specific range, typically ranging from 6.0 to 8.5. This controlled pH range is a critical quality parameter, ensuring the stability and compatibility of CMC with a wide range of formulations and environments.

CMC powder is devoid of any taste. It carries natural resistance to mold and mildew, making it a preferred choice in applications where product spoilage and contamination are concerns. CMC powder is non-toxic, ensuring its safety for use in various industries. Its non-flammable nature adds to its safety profile. CMC powder readily dissolves in water, forming stable solutions or dispersions, making it an ideal choice for formulations requiring a uniform texture or consistency.

Uses

CMC powder is applied and used in formulation of a lot of industrial products. Here are just few examples of where you can use CMC powder:

Oil Drilling

CMC powder is employed as a crucial component of drilling fluids. It serves multiple purposes, including viscosity control, filtration control, and shale inhibition. CMC powder helps maintain the stability of the wellbore by preventing fluid loss and controlling the viscosity of the drilling fluid. This ensures efficient drilling operations and the protection of the wellbore’s structural integrity.

Detergent

CMC powder is an essential ingredient in many detergent formulations. Its water-soluble nature allows it to disperse and dissolve effectively in water, which is vital for creating liquid and powdered detergents. CMC functions as a surfactant, facilitating the removal of dirt and stains from fabrics. It also helps in preventing redeposition of soil onto the cleaned surfaces by keeping the dirt particles suspended in the wash water. Additionally, its thickening properties contribute to the desired texture of liquid detergents.

Textile

In the textile industry, CMC powder serves as a sizing agent. It is applied to textile fibers to improve their strength and handle during weaving and subsequent processing. CMC helps control the absorption of dyes and chemicals, ensuring uniform coloration and treatment of textiles. CMC powder can act as a thickener in dye pastes, providing the necessary consistency for dyeing operations.

Painting

CMC powder finds applications in the production of water-based paints and coatings. It acts as a rheology modifier, enhancing the paint’s viscosity and flow properties. This ensures that the paint can be easily applied, spreads evenly, and adheres well to surfaces. CMC also contributes to the stability and shelf life of paint formulations, preventing settling and separation of pigments.

Ceramic

In the ceramic industry, CMC powder plays a role as a binder and plasticizer. It is added to ceramic compositions to improve their plasticity and workability, making it easier to shape and mold ceramics. CMC also helps control the drying process, reducing the likelihood of cracking or warping during drying and firing. Additionally, it can act as a suspending agent in ceramic glazes.

Packing

Typically, CMC powder is meticulously packed in three-layer paper bags with an inner polyethylene bag for added protection. The three-layer paper bag provides robust structural support, preventing the CMC powder from being easily damaged or compromised. Each bag is carefully filled to contain a net weight of 25 kilograms. This standardized packaging not only ensures convenience and ease of handling but also simplifies inventory management for suppliers and end-users.

What is CMC Powder Used For?

CMC powder plays a pivotal role as a fluid loss controller. When drilling into underground reservoirs, drilling fluids are essential for maintaining wellbore stability and carrying drill cuttings to the surface. CMC powder’s adhesive properties make it an effective tackifier in various applications. It is commonly used in industries such as construction and woodworking, where it enhances the adhesion of materials like wood, paper, or textiles. Carboxymethylcellulose also serves as a rheological additive, influencing the flow and deformation behavior of products. In applications like paints, coatings, and food products, Carboxymethylcellulose adjusts the viscosity and texture of solutions.

Is CMC a Thickening Agent?

The answer is yes. CMC powder is a versatile thickening agent widely used in various industries. Its exceptional thickening capabilities stem from its unique ability to interact with water molecules, forming a viscous solution or gel.

Is CMC a Stabilizer or Emulsifier?

The answer is both yes. Carboxymethylcellulose Sodium serves a dual role as both a stabilizer and an emulsifier in various industrial applications, including paints, oil drilling, and adhesives.
