Viscosity of Blended Sodium Alginate

Sodium-alginate toxicity in mice.

Sir, Sodium alginate consisting chiefly of the sodium salt o. alginic acio is widely used fOI its suspending, emulsifying, thickening and water binding properties (1,2.). Besides its utility at other places in pharmacological laboratories it is one of the popular emulsifiers, used to bring various substances into emulsion for experimental purposes. While conducting toxicity studies of some drug...

Calcium alginate/PVA blended nano fibre matrix for wound dressing

The nanocomposite web of calcium alginate and polyvinyl alcohol with varying proportion has been prepared by electrospinning and its application for wound healing is examined. Scanning electron microscope and Fourier transform infrared spectroscopy have been used to characterize the morphology and molecular fingerprint. The water vapour transmission rate of the blended nanofibre composite web h...

Evaluation of hydrophilic matrix tablets based on Carbopol(®) 971P and low-viscosity sodium alginate for pH-independent controlled drug release.

BACKGROUND The aim of this study was to evaluate matrix tablets containing different ratios of Carbopol(®) 971P (CP) to low-viscosity sodium alginate (SA) and assess their suitability for pH-independent controlled drug release. METHODS Two processing methods (physical mixing, PM and spray-drying, SD) were applied before compaction and the release from corresponding matrices was compared. The ...

Diffusion coefficients in viscous sodium alginate solutions

Department of Applied Physics, University of Fukui, Bunkyo 3-9-1, Fukui, 910-8507 Japan Abstract Sodium alginate solution, being viscous hydrocolloid, was examined voltammetrically in the context of viscous effects by use of a ferrocenyl compound as a redox probe. Voltammograms were almost independent of concentrations of sodium alginate even in a solid-like state. Diffusion coefficients of the...
