Analytical methods using X-ray absorption spectroscopy for quantifying or evaluating metal ions in a dentifrice

Abstract:

The disclosure contains a method of quantifying and/or evaluating metal ions in a dentifrice, wherein the method comprises subjecting the dentifrice to X-ray absorption spectroscopy (XAS), and wherein the XAS is used to measure and/or evaluate the metal ions in the dentifrice. Also disclosed are methods of selecting and screening for dentifrices based upon the evaluation and quantification of their metal ion content.
