Abstract
Ultraviolet and nuclear magnetic resonance spectroscopy have been used to examine the location of benzoic acid within the cetomacrogol micelle. Evidence has been obtained that the solubilised benzoic acid is probably located at the junction of the hydrocarbon nucleus and oxyethylene palisade layer, supporting the hypothesis advanced earlier on the basis of potentiometric observation.
