Aqueous solutions of hydroxyzine and some phenothiazine compounds have
been studied. Electrical conductivity and light scattering measuremen
ts have been performed to characterize the hydroxyzine, promazine, chl
orpromazine and promethazine hydrochlorides micelles. The critical mic
elle concentrations, their shape and size, the number of charges on th
eir surface and the thermodynamic functions have been evaluated.
