Abstract
The aggregation of dodecyltrimethylammonium hydroxide (DTAOH) in aqueo us NaOH solutions was studied as a function of NaOH concentration. As in NaOH-free DTAOH aqueous solutions, the surfactant underwent a stepw ise aggregation mechanism. Changes in the structure of aggregates prod uced an increase of the concentration at which premicellar aggregates could solubilize hydrophobic dyes and also in the concentration at whi ch hydroxide ions join the aggregates.
