Interaction of sodium carboxymethylcellulose with methyllcellulose and polyacrylamide

Archives of Biochemistry and Biophysics, 1965
Abstract By the use of electrophoretic analysis, interactions were shown to occur between an anionic polyelectrolyte, sodium Carboxymethylcellulose (SCMC), and the “neutral polymers,” methylcellulose (MC) and polyacrylamide (PAM). The concentration of the individual polymers was varied to determine the stoichiometry of the reaction in acetate buffer,

A Nonaqueous Titration Assay for Sodium Carboxymethylcellulose

Journal of the American Pharmaceutical Association (Scientific ed.), 1955
Sodium carboxymethylcellulose may be assayed for its content of sodium by titration, following preliminary heating with glacial acetic acid, with 0.1 N perchloric acid.

Ionotropic crosslinking of sodium carboxymethylcellulose and sodium carboxymethylcellulose‐gelatin matrices and their erosion properties

Journal of Applied Polymer Science, 1993
AbstractHydrophilic sodium carboxymethylcellulose (NaCMC) matrices were chemically modified into hydrophobic gels by ionotropic crosslinking with cupric or ferric ion under ambient temperature and pH. Insoluble matrices were also prepared using an interactive polymer gelatin in combination with NaCMC. These matrices underwent erosion at the crosslinks,

Sodium Carboxymethylcellulose(CMC)

2022
Sodium 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.

Effect of sodium carboxymethylcellulose on the blood cells

The American Journal of Digestive Diseases, 1952
1. A large daily dose of sodium carboxymethylcellulose was given to a group of patients for a six month period. 2. Careful study of the effect on the blood cell constituents was made. 3. No significant effect on the blood cell constituents could be ascertained as resulting from the administration of sodium ...

THE MOLECULAR CHARACTERIZATION OF SODIUM CARBOXYMETHYLCELLULOSE

1952
Abstract : Light-scattering and viscosity studies were made on unfractionated sodium carboxymethylcellulose, having 1.15 carboxymethyl groups per glucose unit, in 0.5, 0.05, and 0.01 M NaCl. The molecular weight, which was constant in the ionic strength range studied, and the normal concentration dependence of the scattering showed that aggregation was

Interaction of 5-fluorouracil with sodium carboxymethylcellulose

Colloid & Polymer Science, 1982
The interaction of an anticancer drug, 5-fluorouracil with sodium carboxymethylcellulose in aqueous solution was studied with a spectral method and viscosity measurement. From the binding data, the standard molar change in enthalpy, entropy and the number of binding sites on polymer were calculated.

The dietary effects of sodium carboxymethylcellulose in man

Food Hydrocolloids, 1986
Abstract Following a 7-day control period, five male volunteers consumed 15 g sodium carboxymethyl-eellulose (CMC) daily for 23 days. The CMC was well tolerated with no adverse effects on any volunteer. The daily intake of CMC exceeded, by a factor of 7.5, the acceptable daily intake (ADI) recommended for cellulose and its derivatives (group ADI = 25

Viscosity properties of sodium carboxymethylcellulose solutions

Cellulose, 2007
Through viscosity measurements, concentration and temperature dependences of viscosity of sodium carboxymethylcellulose (CMC) solution were recorded. Effects of glycerin, mechanical shearing and several electrolytes on the CMC solution were also determined.

Determination of sodium carboxymethylcellulose in detergent products

Journal of the American Oil Chemists' Society, 1972
AbstractSodium carboxymethylcellulose in detergent products reacts with phenol in a sulfuric acid media to give a colored reaction product, the absorbance of which is measured at 490 mµ. No interference was experienced from the normal constituents of detergent products. The reproducibility was found to be±0.05% absolute.
