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...

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 larger w/o microemulsion region than the pure surfactants in surfactant/l-hexanollndecane/ water system Maximum water solubility is found at 65.0 weight percent of n-decane and 35.0 weight percent of SDS-SCA-CJI130H. Polymers, mPEG2,000 and PEG8,000 are then added into the line above in the solution. The SDS-SCACJI130H- CIOH221H20/mPEG2,000 system is observed to have a bigger isotropic region than the SDS-SCA-CJI130H-CIOH2 20IPEG8,000 system These two systems are sensitive to temperature where the isotropic region change dramatically as temperature is increased. Nuclear Magnetic Resonance (NMR) is used to detect the interaction and the degree of freedom of the molecules in the isotropic solution which consist of SDS, SCA, CJI130H, ClOH22 aDd H20.

The only interaction between the molecules are found in the SDS- SCA-CJI130H-Cl(JI2:zIH20ItnPEG2,OOO and the SDS- SCA-CJI130H-C1oH221H20fPEG8,OOO systems.

The presence of the polymers, mPEG2,OOO and PEG8,OOO in the SDS-SCA-CJI130HlC1oH2:zIH20 system can break the w/o microemulsion.
