Determine total fluoride content in Colgate dentifrices

ABSTRACT

10 samples of Colgate dentifrice marketed in Vietnam were analysed in this study. The total fluoride content of each sample was determined by measuring the voltage of level-known standard solutions and that of sample test solutions, using Fluoride Selective Electrodes. The results revealed that total fluoride content of these samples is high, stable and not lower than level of 1,000 - 1,200 ppm in samples.
