The dosage of sodium carboxymethyl cellulose (CMC) in detergent products can vary depending on several factors, including the specific formulation, desired viscosity, cleaning performance requirements, and the type of detergent (liquid, powder, or specialty). Here’s a general guideline for determining the dosage of sodium CMC in detergent products:

1. Liquid Detergents:
   • In liquid detergents, sodium CMC is typically used as a thickening and stabilizing agent to improve the viscosity and stability of the formulation.
   • The dosage of sodium CMC in liquid detergents usually ranges from 0.1% to 2% of the total formulation weight.
   • Start with a lower dosage of sodium CMC and gradually increase it while monitoring the viscosity and flow properties of the detergent solution.
   • Adjust the dosage based on the desired viscosity, flow characteristics, and cleaning performance of the detergent.
2. Powdered Detergents:
   • In powdered detergents, sodium CMC is used to enhance the suspension and dispersibility of solid particles, prevent caking, and improve overall performance.
   • The dosage of sodium CMC in powdered detergents typically ranges from 0.5% to 3% of the total formulation weight.
   • Incorporate sodium CMC into the powdered detergent formulation during the blending or granulation process to ensure uniform dispersion and effective performance.
3. Specialty Detergent Products:
   • For specialty detergent products such as dishwashing detergents, fabric softeners, and industrial cleaners, the dosage of sodium CMC may vary depending on specific performance requirements and formulation objectives.
   • Conduct compatibility testing and dosage optimization experiments to determine the optimal concentration of sodium CMC for each specialty detergent application.
4. Considerations for Dosage Determination:
   • Conduct preliminary formulation experiments to evaluate the effect of varying sodium CMC dosages on detergent performance, viscosity, stability, and other key parameters.
   • Consider the interaction between sodium CMC and other detergent ingredients, such as surfactants, builders, enzymes, and fragrances, when determining the dosage.
   • Perform rheological tests, viscosity measurements, and stability studies to assess the impact of sodium CMC dosage on the physical and performance characteristics of the detergent product.
   • Adhere to regulatory guidelines and safety considerations when formulating detergent products with sodium CMC, ensuring compliance with approved usage levels and specifications.
5. Quality Control and Optimization:
   • Implement quality control measures to monitor the performance and consistency of detergent formulations containing sodium CMC.
   • Continuously evaluate and optimize the dosage of sodium CMC based on feedback from product testing, consumer trials, and market performance.

By following these guidelines and considering the specific requirements of each detergent product, manufacturers can determine the optimal dosage of sodium carboxymethyl cellulose (CMC) to achieve desired performance, viscosity, stability, and cleaning efficacy.
