Interaction of Poly(Ethyleneglycol) Ether in Isotropic Region, L2, of Mixed Sodium Dodecyl Sulphate (SDS) - Sodium Caprylate (SCA) System

Mixed surfactants of SDS-SCA at weight ratio of 2:3 in SDS-SCAI CJI130HlH20 system gives the largest inverse micelle region. This system is used for further construction of the wlo microemulsion phase diagram where n-decane is added into the system The SDS-SCA-CJI130HlCuJlnlH20 system shows a lar...
