Critical micelle concentration was determined by surface tension

Aggregation number was determined by the florescence quenching experiment using pyrene as a probe and cetylpyridinium chloride as a quencher.

Polarities of the surfactants were determined using ratio of the fluorescence intensity (I₁/I₃) of pyrene.
