Abstract
A cleaning composition including an ionic liquid, and preferably no co-surfactants are provided. The compositions are substantially free of alkyl phenol ethoxylates, including nonyl phenol ethoxylates. The cleaning compositions provide superior cleaning efficacy for various soils, including proteins and food soils, providing an effective, biorenewable, environmentally friendly alternative to nonyl phenol ethoxylates.
