Abstract: In this study, efforts are made to replace the conventional active matter alpha olefin sulphonate (AOS) from detergent by malinised kraft black liquor (MKBL). Aim is to find the suitability of organic phenolic polymeric structure of lignin (50% lignin in black liquor) as a useful ingredient in detergent formulation with total substitute of AOS. Process has been developed to replace AOS up to 100% by MKBL. Based on surface tension, detergency and foam volume, prepared compositions are on par or sometimes better than commercial detergents even at very low concentration (0.25%).
