Preparation of amidated derivatives of carboxymethylcellulose
International Journal of Biological Macromolecules, 2015Carboxymethylcellulose (CMC) was selected as substrate for amidation based on previous results described for monocarboxy cellulose (MCC) with the aim to prepare highly substituted products. In comparison with MCC containing uronic carboxyl groups at C-6 position, O-carboxymethyl groups in CMC should be more accessible for reagents because they are more

Sodium Carboxymethylcellulose(CMC)
2022Sodium carboxymethylcellulose (CMC) was developed in Germany during the World War I era as a potential substitute for gelatin. However, technical difficulties and high production costs stifled and delayed full-scale commercialization of CMC at that time.

Ionic Linking of Carboxymethylcellulose
Chemistry of Natural Compounds, 2005Binding of Al3+, Cu2+, and Co2+ ions by carboxymethylcellulose (CMC) macromolecules was studied by potentiometric titration. It has been shown that the metal ions bind electrostatically over a wide pH range. Viscosimetry has found that the effectiveness of intermacromolecular CMC binding increases with increasing initial CMC concentration and in the ...

USE OF CARBOXYMETHYLCELLULOSE IN LOTIONS
Archives of Dermatology, 1949Jansen1first developed carboxymethylcellulose in Germany in 1918 as a substitute for gelatin, glue, agar-agar, tragacanth and similar substances. Carboxymethylcellulose is used chiefly in industry in the form of its sodium salt. Sodium carboxymethylcellulose is indicated whenever hydrophilic colloids having suspending, stabilizing, film-forming and ...

Separable Urinary LH by Carboxymethylcellulose Chromatography
Endocrinology, 1965Concentrates of urinary gonadotropin (fraction B) of men, postmenopausal women and eunuchs were applied to carboxymethylcellulose (CMC) columns in 0.01M ammonium acetate solution at pH 6.0. A nonretained fraction was obtained and then the material on the column was eluted with 0.5M ammonium acetate to yield a retained fraction.
