Analytical and stability studies on medical cosmetics
AbstractTwo simple and sensitive spectrofluorimetric (method Î™) and spectrophotometric (method Î™Î™) methods have been developed for the determination of some chloride containing toothpastes and panthenol-containing cosmetic preparations respectively. Method Î™ is based on quantitative fluorescence quenching of (terbium-salicylate-hexamine ternary complex) by fluoride which could be measured at Î»em/Î»ex of 547nm/322nm. The âˆ†Fconcentration plot was rectilinear over the concentration range of 0.5-20 Âµg/ml. Method Î™Î™ depends reaction of panthenol with nitrobenzoxadiazole chloride (NBD-Cl) and measuring the absorbance of the resultant product at 480nm. The absorbance- concentration plot was rectilinear over the concentration range of 2-20 Âµg/ml
