The ultrasonic velocity of molecules in medium supplies valid information about the binding forces between molecules. Surfactants are chemicals that self-assemble molecular clusters in a solution (oil or water phase) known as micelles. SLS has been suggested as a potentially effective topical microbicide for intravaginal usage to suppress and potentially prevent infection by various enveloped and non-enveloped viruses. The acoustical parameters such as ultrasonic velocity, density, and viscosity of a solution containing an anionic surfactant (SLS) and alcohols (Anise and Cinnamyl alcohol) are determined at various temperatures (303,313 and 323 K). Similarly, the acoustical parameters such as adiabatic compressibility (b), intermolecular free length (Lf), internal pressure () Rao's constant (Ra), absorption coefficient (a/f2), free volume (Vf), cohesive energy (CE), relaxation time (), acoustic impedance (Za), and solvation number (Sn) were calculated from the observed values. At the end, it is concluded that SLS+water- Anise alcohol has been used as a best additive. This composite has a lower foaming tendency due to lower surface tension, leading to a newer product.
