Abstract
Fatty acid sanitizer concentrates and diluted final solutions are provided which include individual amounts of germicidally effective fatty acid, hydrotrope, strong 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 2.5%-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.
Claims16
An aqueous, dilutable acid sanitizer concentrate composition comprising individual amounts of water, from about 2-12% by weight of an aliphatic C.sub.6 -C.sub.10 germicidally effective fatty acid, from about 5-20% by weight of hydrotrope-solubilizer selected from the group consisting of the alkane sulfonates and disulfonates, from about 5-40% by weight of a strong acid selected from the group consisting of phosphoric and sulfuric acids and mixtures thereof, and a component for giving the composition enhanced stability, said stabilizing component comprising an effective amount of from about 3.5-15% by weight of a weak acid selected from the group consisting of propionic, butyric and valeric acids and mixtures thereof, said composition, when diluted in water to form a use solution, having a pH of from about 1-5.
A dilutable acid sanitizer concentrate composition comprising:
- about 3% by weight nonanoic acid;
- about 3% by weight decanoic acid;
- from about 8%-30% by weight of a mixture of sodium octane sulfonate and sodium octane disulfonate;
- from about 8%-30% by weight of a strong acid selected from the group consisting of orthophosphoric, sulfuric and mixtures thereof;
- a component for giving the composition enhanced stability and consisting of about 10% by weight of propionic acid;
- and
- the balance of said composition up to 100% by weight being water.
