As the awareness among the consumers is increasing, the detergent industries need to meet challenges and cope with consumers demand for eco–friendly products. Today, the manufacturers are competing to produce detergents with more environmental–friendly properties to remain competitive in the industry. Study was conducted to assess and compare the environmental impacts from the production of surfactant used in detergent, alkylbenzenesulfonates (LAS) and methyl ethyl sulfonates (MES). The difference in term of environmental impacts from LAS manufactured in Malaysia and LAS data available in Ecoinvent database was also assessed. Data and information on the inputs used throughout the production processes was compiled and calculated using Life Cycle Assessment (LCA) procedures, where environmental impacts and hotspots were identified. The functional unit was defined as one kilogram of surfactant. From this study, among the significant environmental impacts for the production of one kilogram surfactant is depletion of fossil fuels, land use change and respiratory inorganics. LAS is the main contributor to the depletion of fossil fuels while the production of MES cause land use change and respiratory inorganics. From the results of this study it can be concluded that MES is a more environmental–friendly surfactant compared to LAS.
