A lubricant composition having biocidal properties comprises a cyclic imidazoline as the active lubricant in combination with sufficient acid to render the imidazoline soluble in water and optionally including amides and nonionic surfactants. The concentrate, when diluted for use, provides biocidal control action against yeasts and bacteria. The concentrate is preferably adjusted to a pH in the range of 3 to 8.
