Thermodynamic, FTIR, 1H-NMR, and acoustic studies of butylated hydroxyanisole and sodium dodecyl sulfate in ethanol, water rich and ethanol rich solutions

► Butylatedhydroxyanisole and sodium dodecyl sulfate interactions are investigated. ► Presences of electrostatic and hydrophobic interactions are evaluated. ► Evaluation of thermodynamic parameters provides the BHA location within micelle. ► BHA undergoes reasonable conformational changes in presence of SDS.
