AI Technical Summary
Conventional detergents and cleaning agents face challenges in achieving high washing performance with concentrated formulations due to the lack of effective surfactant counterions, leading to increased manufacturing, packaging, and transport costs, as well as a larger CO2 footprint.
A neutralization product composed of linear alkylbenzenesulfonic acid (LAS) and ethoxylated fatty amine (EFA) in a molar ratio of 1:20 to 20:1, combined with surfactant polymers and complexing agents, enhances washing performance on greasy soils.
The LAS-EFA combination significantly improves washing performance on greasy soils, particularly when used in washing or cleaning agents containing surfactant polymers and complexing agents, reducing the need for higher dosages and minimizing environmental impact.
