歯磨中のABSの試験について

概要

論文の詳細を見る
Sodium lauryl sulfate (SDS) or sodium N-lauryl sarcosinate (SLS) is contained in toothpaste as forming agent and surfactant. Besides these agents sodium alkyl benzensulfonate (ABS) is suspected to be used for similar purpose. In order to ascertain this suspicion some commercial tooth-pastes (including foreign articles) were tested. In the case of the sample which contained SDS and ABS in the ratio of seven to three ABS was detectable by infrared absorption spectrum as a method for detection. (With this method the presence of SLS had no effect on detection of ABS) Five micrograms of ABS in the mixture composed of 200 mg of SDS and 5 mg of ABS was detectable by paper chromatography of the hydrolysate using pinakryptol yellow as a coloring agent. The surfactants were extructed from the commercial tooth-pastes and tested in this way, but ABS was not detected.
