Sodium Carboxymethyl Cellulose (CMC), or cellulose gum, is a workhorse in many industries due to its remarkable thickening, stabilizing, and binding properties. However, not all CMC is created equal. Understanding the different grades available is crucial for manufacturers to achieve optimal results in their specific applications. This guide from NINGBO INNO PHARMCHEM CO.,LTD. aims to demystify CMC selection for procurement managers and R&D scientists.

What Defines a CMC Grade?

The primary factors differentiating CMC grades are degree of substitution (DS) and viscosity. The DS refers to the average number of carboxymethyl groups per anhydroglucose unit in the cellulose molecule, influencing solubility and chemical reactivity. Viscosity, typically measured in a 1% or 2% aqueous solution, dictates its thickening power.

Key Application Areas and Recommended Grades:

  • Food Industry: For thickening sauces, dairy products, and baked goods, a medium to high viscosity CMC with a DS of 0.7-0.95 is often preferred. These grades enhance texture and stability. When sourcing food grade CMC, ensure it meets relevant food safety standards. We are a reliable food additive CMC supplier in China.
  • Pharmaceuticals: In tablet formulations, CMC acts as a binder and disintegrant. Pharmaceutical grades require high purity (often >99.5%) and specific viscosity profiles. As a trusted pharmaceutical grade CMC manufacturer, we offer products that meet stringent quality requirements. Inquire about our pharmaceutical grade CMC for your formulations.
  • Oil Drilling: CMC is essential for controlling fluid loss and increasing viscosity in drilling fluids. Low to medium viscosity grades are typically used, providing efficient rheological control. Sourcing CMC for oilfield services requires robust performance under demanding conditions.
  • Personal Care & Cosmetics: For products like shampoos, lotions, and toothpaste, CMC provides desired texture and stability. Food grade or specific cosmetic grades are often chosen for their mildness and efficacy.
  • Textiles & Paper: CMC is used as a sizing agent in textiles to improve yarn strength and as a coating additive in paper to enhance smoothness and printability.
