In the SDS/HCl and DTAB/KOH systems, the micellar phase had a fixed composition and was homogeneous and monodisperse above the CMC. However, in the SDS/KOH and DTAB/HCl systems, pH values increased in a continuous and gradual manner below and above the CMC, and the properties of the micellar phase changed with temperature as a function of concentration, giving rise to inhomogeneity and polydispersity.eninfo:eu-repo/semantics/closedAccessCritical Micellar ConcentrationDodecyltrimethylammonium BromideSodium Dodecyl SulfateHydrochloric AcidPotassium HydroxidePhPhase SeparationPhase-BehaviorAqueous-MediumFatty-AcidsMixturesMicellizationSurfactantsChlorideBinaryWaterArticle274487492Q3WOS:0001852823000092-s2.0-0141628506Q331543
