摘要

The discovery of the aggregative optical activity for solutions of different colloid surfactants (anionic sodium dodecyl sulfate, cationic hexadecyltrimethylammonium bromide, and nonionic Brij 30) is reported. The optical activity develops only above the Kraft point, and, in the concentration plot, it is characterized by a distinct maximum in the vicinity of critical micelle concentration. The concentration at which the optical activity disappears corresponds to the formation of spherical micelles and is a new important parameter in the colloid chemistry of surfactants.
