Previously reported results for alcohol ethoxylate surfactants have shown that optimum removal of both nonpolar and sebum‐ like liquid soils from polyester/cotton fabric occurs at the phase inversion temperature (PIT) of the surfactant‐ water‐ soil system. A similar correlation between phase inversion and optimum detergency has been identified for detergent systems containing mixtures of nonionic and anionic surfactants such as alcohol ethoxylates and alcohol ethoxysulfates. Experimental techniques other than direct detergency studies are described which allow determination of the optimum nonionic/ anionic surfactant ratio for removal of a particular soil at a specified temperature. In addition, implications of these results for development of temperature‐ insensitive detergent formulations containing alcohol ethoxylates are discussed.
