    Behavior of surfactant in solutions and on surfaces

    Surfactants reduce the surface tension of solutions but can also change the wettability of solids.

    How to reveal the soil removal efficiency already during the cleaning test

    Soil removal efficiency of a formulation is typically assessed by running a cleaning test followed by an analysis of the result. Here we show how these two steps can be run simultaneously.

    Analysis of protein adsorption to a silicone oil/water interface

    Here we present a summary of how protein adsorption to a silicone oil/water interface was analyzed in the presence and absence of surfactant.

    Time-resolved analysis of surfactant-surface interaction

    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.

    How is the protein-surface interaction influenced by the presence of surfactant?

    Studying protein interaction with various surface materials and at different solution conditions, the conditions that minimize adsorption can be identified. Here we show you one way to do this assessment.

    How Nouryon ranks detergent performance when the traditional tools fail

    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.
