Abstract

Efficacious disinfectant/cleansing compositions for hard surface soil and stain removal, more particularly germicidally effective hard surface cleansers, optionally containing d-limonene.

Claims

1. A germicidally effective, stable aqueous alcoholic hard surface cleaner composition comprising from about 1 to 10 percent, by weight, of a nonionic surfactant having a Hydrophile-Lipophile Balance in the range of about 12.5 to 14, from about 2.5 to 4 percent, by weight, of a germicide consisting of (a) n-dodecylguanidinium hydrochloride and (b) one or more dialkyldimethyl ammonium chlorides, wherein the alkyl groups are independently about C₈ to C₁₂, the ratio of (b) to (a) being at least about 1:

1 to about 3;

1.

2. A composition in accordance with claim 1 which additionally comprises about 2 to 10 percent, by weight, of an alkali detergent builder selected from sodium citrate, potassium citrate, sodium gluconate, potassium gluconate, and the sodium and potassium salts of ethylenediamine tetraacetic acid.

3. A composition in accordance with claim 2 wherein the alkali detergent builder comprises about 2 to 5 percent, by weight, of the composition and is selected from sodium citrate, tetrasodium ethylenediamine tetraacetate, and sodium gluconate.

4. A composition in accordance with claim 1 wherein said non-ionic surfactant is a long-chain (C₁₂ -C₁₅) linear primary alcohol ethoxylate having about 9 moles of condensed ethylene oxide.

5. A composition in accordance with claim 1 wherein said quaternary ammonium compound is a mixture of dioctyl-, didecyl- and octyldecyldimethyl ammonium chlorides.

6. A composition in accordance with claim 1, 2, 3, 4, or 5 which additionally comprises d-limonene.

7. A composition in accordance with claim 6 wherein the d-limonene comprises up to about 4 percent, by weight, thereof.

8. A composition in accordance with claim 6 wherein the d-limonene comprises about 2 to 3.5 percent, by weight, thereof.

9. A composition in accordance with claim 1 wherein the pH is above about 9.5.

10. A composition in accordance with claim 9 which is free of metasilicate and phosphate anions.
