Cleaning, disinfecting and microbicidal compositions
View Patent ↗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.
1. A microbicidal disinfecting composition consisting of:
water; an anionic surfactant; and
an amount of an acidifying agent effective to provide the microbicidal disinfecting composition with a pH value of 7.0 or below, wherein the acidifying agent is selected from the group of an alkali metal bisulfate, ammonium bisulfate, and a combination thereof.
2. The microbicidal disinfecting composition of claim 1 , wherein the alkali metal bisulfate comprises at least one of sodium bisulfate, potassium bisulfate, or a combination thereof.
3. The microbicidal disinfecting composition of claim 1 , wherein the anionic surfactant is present in an amount that ranges from about 0.0001 wt. % to about 50 wt. %, the amount of the acidifying agent ranges from about 0.1 wt. % to about 99.90 wt. %, and the balance is water.
4. The microbicidal disinfecting composition of claim 1 ,
wherein the anionic surfactant comprises at least one C4-C18 acid or salt compound selected from the group consisting of: (1) an alkyl- carboxylate, isethionate, sulfate, sulfonate, sulfoacetate, sulfosuccinate, lactate, lactylate, phosphate, phosphonate, or mixtures thereof; (2) an alkenyl- carboxylate, isethionate, sulfate, sulfonate, sulfoacetate, sulfosuccinate, lactate, lactylate, phosphate, phosphonate, or mixtures thereof; (3) an alkylbenzene- carboxylate, isethionate, sulfate, sulfonate, sulfoacetate, sulfosuccinate, lactate, lactylate, phosphate, phosphonate, or mixtures thereof; (4) a naphthalene- carboxylate, isethionate, sulfate, sulfonate, sulfoacetate, sulfosuccinate, lactate, lactylate, phosphate, phosphonate, or mixtures thereof; or (5) a combination of any of the C4-C18 organic acid or salt compounds of (1)-(4).
5. The microbicidal disinfecting composition of claim 4 , wherein the anionic surfactant comprises at least one of a sulfated alkyl ester, a sulfated aryl ester, a sulfonated alkyl ester, or a sulfonated aryl ester, or combinations thereof.
6. The microbicidal disinfecting composition of claim 5 , wherein the anionic surfactant comprises at least one of sodium dodecyl sulfate, sodium dioctyl sulfosuccinate, sodium decyl lactylate, sodium dodecyl benzene sulfonate, or combinations thereof.
