Alkyd resin polymer was synthesized from oil recovered from spent bleaching earth (ORSBE) and rosin and then used with sodium lauryl sulphate as mixed active matter system in liquid detergent formulation with a view to replace the conventional active matter, linear alkyl benzene sulphonate (LABS). The prepared liquid detergents were analyzed for surface tension, detergency and foaming power and compared with commercial liquid detergent sample. All the liquid detergent compositions exhibited comparable performance to commercial one with respect to detergency and surface tension whereas foaming power decreased with increase in amount of polymer in the formulation. Satisfactory results were found even for low concentration (0.5%) of liquid detergents. The proposed compositions can be easily prepared in existing alkyd resin manufacturing plants with little modification.
