Some resin based ecofriendly liquid detergents

Abstract

In this study, efforts were made to replace from detergent the conventional active matter, linear alkyl benzene sulphonate (LABS) formulation by polymeric surfactant (alkyd resin). An ecofriendly alkyd resin polymer based on soybean oil and rosin was synthesized and used with sodium lauryl sulphate (SLS) instead of LABS for detergent formulation. Based on surface tension, detergency and foam volume, prepared compositions are on par or sometimes better than commercial samples even at very low (0.5%) liquid detergent. The proposed compositions can be easily prepared in existing alkyd resin manufacturing plant. An alternative production line was suggested for existing alkyd resin plants in paint industry.
