  • What is detergent grade CMC?
  • Sodium Carboxymethyl Cellulose, often known as Sodium CMC or CMC, is one of the basic ingredients for detergent powder. Following are four reasons why detergent grade CMC is widely used in detergent powder manufacturing. Firstly, detergent grade CMC can dissolve quickly, which is quite an important factor for detergent powder.
  • What is sodium carboxymethyl cellulose (CMC)?
  • Shi Li, ... Xiao-Dong Guo, in Journal of Power Sources, 2021 Sodium carboxymethyl cellulose (CMC), the most widely used water-based biopolymer binder in the laboratory at present, is a linear derivative of cellulose substituted by β–linked glucopyranose residues and carboxymethyl groups.
  • Is sodium carboxymethylcellulose biodegradable?
  • Screening Assessment Conclusion – Sodium carboxymethylcellulose is classified as a tier 1 chemical and requires a hazard assessment only. Sodium carboxymethylcellulose (Na CMC) is a white or slightly yellowish powder. It is biodegradable, but not readily biodegradable, and it is not expected to bioaccumulate.
  • Is sodium carboxymethylcellulose a cellulosic ether?
  • Sodium carboxymethylcellulose, one of major cellulosic ethers, is widely used as a binding, thickening and stabilising agent (Lee et al. 2018). Pharmaceutical grades of sodium carboxymethylcellulose are available commercially at degree of substitution (DS) values of 0.7, 0.9, and 1.2, with a corresponding sodium content of 6.5%–12% wt.
