The aqueous solubilities of bisphenol A (BPA) in water and water + surfactants have been determined at four different temperatures, 298.15 K, 303.15 K, 308.15 K, and 313.15 K. Results showed that the presence of a cationic surfactant cetyltrimethylammonium bromide (CTAB) caused a significant increase in the solubility of BPA, which increased linearly with the concentration of CTAB. When the anionic surfactants sodium dodecylbenzenesulfonate (SDBS) and dodecyl sodium sulfate (SDS) were added to the solutions, the minimum in the solubility of BPA was found at a lower concentration. However, when a certain concentration was exceeded, a most striking increase in solubility was observed. The sequence of solubility enhancement as a function of the critical micelle concentration is SDS > CTAB > SDBS at 298.15 K and negatively correlates to the hydrophilic lipophilic balance of the surfactants.
