## Abstract

Synergistic combinations of extended chain surfactants and co-surfactants, emulsions or microemulsions and cleaning compositions incorporating the same are provided. In certain embodiments a surfactant system is disclosed which includes extended nonionic surfactants, and a linker surfactant. This system forms stable emulsions or microemulsions with oils, including non-trans fats and fatty acids and these emulsions or microemulsions are stable, irreversible and can be created at low temperature. The cleaning compositions may include the surfactant system alone, a stable emulsion or microemulsion with oil and the surfactant system, a pre-spotter or other pre-treatment or soft surface and hard surface cleaning compositions comprising the surfactant combination.
