Abstract
A microbicidal disinfecting composition and a method of preparing the same include the use of an acidifying agent that comprises at least one of an alkali metal bisulfate, ammonium bisulfate, or a combination thereof. The composition has broad-spectrum microbicidal properties and does not demonstrate cloudiness or precipitation when prepared, diluted, or otherwise exposed to hard water.
Claims11
A microbicidal disinfecting composition, consisting of:
- an antimicrobial agent in an amount ranging from about 0.0001 wt. % to about 50 wt. %, based on the total composition weight, wherein the antimicrobial agent is selected from the group consisting of an anionic surfactant, a nonionic surfactant, and combinations thereof;
- a fungicidal agent present in a positive amount of up to about 10 wt. %, based on the total composition weight, the fungicidal agent being selected from the group consisting of a copper salt, a zinc salt, and a combination thereof;
- an acidifying agent that consists of an amount of an alkali metal bisulfate effective to provide the microbicidal disinfecting composition with a pH value of 7.0 or below;
- and
- optionally, including one or more of water, a preservative, a flavoring agent, a coloring agent, a freeze thaw modifying agent, lactic acid, a sequestering agent, or a combination thereof;
- wherein said preservative when present is selected from the group consisting of a free acid, a salt or an ester form of benzoic acid, sorbic acid, ascorbic acid, and erythorbic acid.

A microbicidal disinfecting composition, consisting of:
- an anionic surfactant having antimicrobial activity, the anionic surfactant being present in an amount that ranges from about 0.0001 wt. % to about 50 wt. % of the microbial disinfecting composition;
- an amount of sodium bisulfate, potassium bisulfate, ammonium bisulfate, or combinations thereof, effective to provide the microbicidal disinfecting composition with a pH of 7.0 or less;
- lactic acid;
- and
- optionally, one or more of water, an anti-microbial nonionic surfactant, a fungicidal agent, a preservative, a flavoring agent, a coloring agent, a freeze thaw modifying agent, a sequestering agent, or combinations thereof;
- wherein said preservative when present is selected from the group consisting of a free acid, a salt or an ester form of benzoic acid, sorbic acid, ascorbic acid, and erythorbic acid.
3 more elements
A microbicidal disinfecting composition, consisting of:
- at least one microbicidal alkylbenzene sulfonate;
- lactic acid;
- a second acidifying agent that consists of an amount of an alkali metal bisulfate, ammonium bisulfate, or combinations thereof, that is effective to provide the microbicidal disinfecting composition with a pH of 7.0 or less;
- and
- optionally, including one or more of water, a nonionic surfactant, a fungicidal agent, a preservative, a flavoring agent, a coloring agent, a freeze thaw modifying agent, a sequestering agent, or a combination thereof;
- wherein said preservative when present is selected from the group consisting of a free acid, a salt or an ester form of benzoic acid, sorbic acid, ascorbic acid, and erythorbic acid.
