Abstract
Abstract In this study, we have investigated the development of liquid laundry detergent formulations over the past 10 years with regard to performance and sustainability profiles. We found that between 2001 and 2011, wash performance has significantly increased while at the same time the surfactant level was substantially reduced, leading to lower Global Warming Potential and improvements in all other relevant lifecycle indicators. One driver is the partial replacement of surfactants with other, more effective ingredients like enzymes that allow for additional performance dimensions and new consumer-relevant benefits. Future surfactant systems that help increase and support the stability and functionality of enzymes will further boost performance at low temperature, improve storage stability and enable more concentrated formulations at competitive costs.
