Surfactants are key components in many products and processes where the surfactant-surface interaction dynamic could be critical. Here we show how the surfactant interaction with surfaces can be analyzed in a time-resolved manner at the nanoscale.
When, Nouryon (former AkzoNobel speciality chemicals), launched a new surfactant with a good dermatological profile, they wanted to prove superior performance vs competitive benchmarks. As the current test methods were not sensitive enough, they turned to an analysis using QSense cleaning profile.
What is the optimal surfactant concentration to use in a cleaning formulation? Here we show how the cleaning efficiency as a function of detergent concentration can be assessed within an hour.
