Carbohydrate Polymers, 2003
The sugar beet pulp cellulose was converted carboxymethyl cellulose (CMC) by etherification and the process of carboxymethylation was optimised with respect to the solvent medium, alkali concentration, sodium chloroacetate amount, temperature and time of reaction.

Synthesis and characterization of seaweed cellulose derived carboxymethyl cellulose
Carbohydrate Polymers, 2017In the present study, cellulose (SWC) extracted from green seaweed Ulva fasciata was processed to synthesize carboxymethyl cellulose (SWCMC). The seaweed cellulose (∼15% DW) was first processed for α cellulose extraction (10.1% on DW) followed by the synthesis and characterization of SWCMC.

The precipitation of proteins by carboxymethyl cellulose
Journal of Dairy Research, 1975SummaryCarboxymethyl cellulose (CMC) formed insoluble complexes with β-lactoglobulin, bovine serum albumin and Na caseinate. Maximum precipitation of the β-lactoglobulin-CMC complex occurred at pH 3·2, whereas maximum precipitation of the bovine serum albumin-CMC complex and the Na caseinate-CMC complex occurred at pH 2·8.

Cellulose Nanocrystal-Filled Carboxymethyl Cellulose Nanocomposites
Journal of Nanoscience and Nanotechnology, 2006Polymer nanocomposites are one of the important application areas for nanotechnology. Naturally derived organic nanophase materials are of special interest in the case of polymer nanocomposites. Carboxymethyl cellulose is a polyelectrolyte derived from natural materials. It has been extensively studied as a hydrogel polymer.

Rheological insights on Carboxymethyl cellulose hydrogels
International Journal of Biological Macromolecules, 2023Hydrogels are copiously studied for tissue engineering, drug delivery, and bone regeneration owing to their water content, mechanical strength, and elastic behaviour. The preparation of stable and mechanically strengthened hydrogels without using toxic crosslinkers and expensive approaches is immensely challenging.

Carboxymethylation of Bacterial Cellulose
Macromolecular Symposia, 2010AbstractThe carboxymethylation of bacterial cellulose (BC) was studied under typical heterogeneous reaction conditions. It was found that the BC possesses a significantly lower reactivity compared to wood cellulose converted under comparable conditions.

Modification of carboxymethyl cellulose through oxidation
Carbohydrate Polymers, 2012The periodate oxidation reaction of carboxymethyl cellulose involve the primary and secondary hydroxyl groups of the pyranose ring. The reaction is accompanied by the opening of the pyranose ring and resulting product is dialdehyde carboxymethyl cellulose along with some hydrated forms.

Ultrasound mediated enzymatic hydrolysis of cellulose and carboxymethyl cellulose
Biotechnology Progress, 2013A recombinant Trichoderma reesei cellulase was used for the ultrasound‐mediated hydrolysis of soluble carboxymethyl cellulose (CMC) and insoluble cellulose of various particle sizes. The hydrolysis was carried out at low intensity sonication (2.4–11.8 W cm−2 sonication power at the tip of the sonotrode) using 10, 20, and 40% duty cycles.
