A Natural Dye in a Mesophase Region of Cetyltrimethylammonium Bromide/ Octan-l-ol/Water System

A naturally occurring dye, curcumin, was added to a series of lamellar liquidcrystal mesophases consisting of cetyltrimethylammonium bromide (CTAB),octan-1-o1 and water at 30°C. The changes brought about by the addition of the natural dye were followed by optical microscopy and small angle X-ray dif...
