Anionic-Anionic Mixed Aqueous Micellar Systems-A Study to Explore Synergistic Effects on Micellisation

The present study has been initiated with a view to explore synergistic effects on micellar behaviour of anionic - anionic mixed aqueous micellar systems. The conductometric technique has been used to measure the specific conductivity of the aqueous surfactant systems involving alkali metal dodecylsulphates (abbreviated as LiDS, NaDS, KDS) in presence of microquantity (1.0 x 10^-4 mol. dm^-3) of various anionic surfactant additives viz. caprate, laurate, myristate, and dodecylsulphates of Li, Na, K metals. The comparative assessment of the data reported in Table I and Table II suggest that micellisation is facilitated in presence of the above cited additives i.e., cmc is lowered with additives.
