an ethoxylated phenol having formula III

wherein T is an average of 3 to 8; and
a cleaning surfactant.

2. The aqueous cleaning formulation of claim 1 , wherein the essential oil is selected from the group consisting of lavender oil, rosemary oil, thyme oil, D-limonene, α-pinene and mixtures thereof.
