The interaction of twenty three dyes with four surfactants was studied by UV absorption spectroscopy. Out of the ninety two combinations tried, different observations were noted. They include bathochromic, hypsochromic, hyperchromic and hypochromic shifts and change of pH. Shift of the max value observed ranged from 0 to 89 nm for various combinations and change of pH from a maximum of about 6.85 to a minimum of about 3.80. Five dyes are recommended to be used with all the four surfactants. Another five dyes were found suitable with three surfactants. Two dyes are found useful for two surfactants. There are also few single combinations of dye-surfactants which are noted. Overall forty seven combinations were found satisfactory out of ninety two. On basis of change of pH use of tween 80 with all the twenty three dyes is preferred. These readymade observations will be of help to the researchers in selecting dye-surfactant combinations by cutting on the money and time spent for finding them through experiment.
