Abstract
Fatty acid sanitizer concentrates and diluted final solutions are provided which include individual amounts of germicidally effective fatty acid, hydrotrope, strong acid selected from the group consisting of phosphoric and sulphuric acid sufficient to lower the pH of the final solutions to about 1-5, and a concentrate stabilizing weak acid component selected from the group consisting of propionic, butyric and valeric acids and mixtures thereof. The concentrate stabilizing component enhances the room and low temperature phase stability of the concentrates, even when used at very low levels typically ranging from 3.5%-15% by weight. Preferably, the fatty acid is a mixture of nonanoic and decanoic acids, whereas the strong acid is selected from the group consisting of orthophosphoric, sulfuric and mixtures thereof. Alternately, stable concentrates and use dilutions can be provided using undecylenic acid, either alone or in combination with other fatty acids.
