CMC (Carboxymethyl Cellulose) is a water-soluble cellulose-based polymer valued for its excellent thickening, stabilizing, binding and rheology-modifying properties. When dispersed and hydrated in water, it can increase viscosity and help provide desirable texture and consistency to formulations.
Its versatility makes CMC suitable for applications ranging from personal care and cosmetics to food, household products, detergents, paints, adhesives and various industrial formulations.
In cosmetic and personal care products, CMC can help improve the viscosity and stability of water-based formulations while contributing to a smooth and consistent product texture. It can also assist with suspension and formulation structure.
The performance of CMC depends on factors such as viscosity grade, degree of substitution, concentration, temperature, pH and formulation composition. The appropriate grade should therefore be selected according to the intended application.

Formulation Functions
Thickener: Increases viscosity in suitable aqueous systems.
Rheology Modifier: Helps control the flow and consistency of formulations.
Stabilizer: Can contribute to formulation stability and uniformity.
Binder: Useful for binding and improving cohesion in selected applications.
Suspending Aid: Can assist in keeping suitable dispersed particles uniformly distributed.
Film Former: May contribute to film formation in certain water-based formulations.
Formulation Uses
CMC is generally dispersed in water and allowed to hydrate adequately before evaluating the final viscosity. Proper dispersion is important to minimize lump formation and achieve consistent hydration.
The required usage level depends on the CMC grade, target viscosity, product type and formulation composition. Lower concentrations may provide moderate viscosity, while higher concentrations generally produce greater thickening.
For cosmetic formulation development, CMC can be combined with other suitable gums, polymers and rheology modifiers when required. Compatibility and stability should always be evaluated before commercial production.

Handling & Safety
Handle CMC according to the applicable Safety Data Sheet (SDS) and supplier technical documentation.
Avoid generating or inhaling excessive powder dust during handling. Use suitable personal protective equipment and adequate ventilation when working with bulk quantities.
Always verify the specific product grade, specifications and intended application before formulation or commercial use.
Storage Information
Store CMC in a cool, dry and well-ventilated area in a tightly closed container. Protect from moisture, humidity, direct sunlight and contamination.
Because CMC is moisture-sensitive, keep the packaging properly sealed when not in use. Follow the manufacturer’s recommended storage conditions and shelf-life information.
