Industrial Fluid

Abstract

An industrial fluid is disclosed. The fluid comprises an oleaginous component, an aqueous component, and a surfactant dispersed in the aqueous component. The average micelle diameter follows a Gaussian distribution having a mean, μ, and wherein the standard deviation σ is less than or equal to 0.2μ. The industrial fluid is also substantially free from defoamers or anti-foam compounds.
