Abstract
This invention is a microbicidal and tuberculocidal composition comprising a major portion of carrier and an effective sanitizing amount of octanoic acid, or octanoic acid derivatives, and a sulfur containing compound. Optionally, the invention may also comprise any variety of formulatory ingredient options or application adjuvants. The invention comprises concentrate compositions and methods of sanitizing and disinfecting using the antimicrobial composition of the invention.
Claims9
A method of using an antibacterial composition, said method comprising the steps of:
- (a) providing an antimicrobial composition consisting essentially of a major portion of carrier and an effective tuberculocidal amount of octanoic acid, an octanoic acid ester or salt thereof, and a sulfur containing compound;
- said compound selected from the group consisting of an alkyl sulfate or sulfonate, an aryl sulfate or sulfonate, an alkylaryl sulfate or sulfonate, and mixtures thereof, at a ratio of about 1.05-10 of octanoic acid to sulfur compound and at a pH of about 1.3 to 4.0;
- and
- (b) applying said composition to the intended surface for at least ten minutes.
A use dilution antimicrobial composition consisting essentially of a major portion of carrier selected from the group consisting of an aqueous solvent, an organic monofunctional alcohol, an organic polyfunctional alcohol and mixtures thereof;
- an antimicrobial consisting of about 0.01 wt-% to 0.50 wt-%, based on the composition as a whole, of octanoic acid, an octanoic acid ester or salt thereof, and about 0.01 wt-% to 0.50 wt-%, based on the composition as a whole, of dodecyl benzene sulfonate or a linear alkyl sulfonate, and an acidulant selected from the group consisting of phosphoric acid, sulfuric acid, sulfuric acid, adipic acid, tartaric acid, succinic acid, acetic acid, fumaric acid, propionic acid, citric acid, malic acid, lactic acid, and mixtures thereof, wherein the volume ratio of carrier to antimicrobial is a minimum of about 256:1 and the compositional pH is from about 1.3 to 4.0.
A solid antimicrobial composition consisting essentially of a major portion of carrier, said carrier comprising a solidifying agent that is selected from the group consisting of an organic hardening agent, an inorganic hardening agent, and mixtures thereof;
- an antimicrobial consisting of about 0.01 wt-% 0.50 wt-%, based on the composition as a whole, of octanoic acid, an octanoic acid ester or salt thereof, and about 0.01 wt-% to 0.50 wt-%, based on the composition as a whole, of dodecyl benzene sulfonate or a linear alkyl sulfonate, and an acidulant selected from the group consisting of phosphoric acid, sulfuric acid, sulfamic acid, adipic acid, tartaric acid, succinic acid, acetic acid, fumaric acid, propionic acid, citric acid, malic acid, lactic acid, and mixtures thereof.
A liquid concentrate antimicrobial composition comprising:
- (a) an antimicrobial agent consisting of about 0.5-45 wt-% octanoic acid, an octanoic acid ester or salt thereof, and about 0.5-45 wt-% of dodecyl benzene sulfonic acid;
- (b) from about 0.1 to 90 wt-% hexylene glycol;
- (c) from about 0.02 to 40 wt-% nonionic surfactant, said surfactant comprising from about 5 to 15 moles ethylene oxide and from about 10 to 30 moles propylene oxide;
- and
- (d) a balance of water.
