SPECTROPHOTOMETRIC ESTIMATION OF PPM LEVEL OF SURFACTANTS IN COMMERCIALLY AVAILABLE TOOTHPASTES BY SOLVENT EXTRACTION

A spectrophotometric approach for the detection of surfactants in commercially available toothpastes has been proposed in this paper. In this work, content of anionic surfactants in different samples of toothpastes was determined by spectrophotometrically. Method to estimate the amount of surfactants present in various samples of toothpastes, we have applied solvent extraction method combined with visible spectrophotometry. The formation of ionic pair between anionic surfactants (AS) and methylene blue (MB). Ionic-pair complex is determined by spectrophotometrically at the absorbance 660 nm. Parts per million levels of surfactants were estimated from commercially available toothpastes. The results of this study shows that the level of surfactants in the toothpastes studied follows the order, Colgate strong-teeth Colgate Max-fresh Pepsodent Daber red Paste Meswak
