Abstract

The present invention relates to a hard surface cleaning composition comprising from about 0.1 percent by weight to about 50 percent by weight, basis the total weight of the composition, of one or more secondary alkyl sulfate compounds.

Claims

1. A hard surface cleaning composition comprising from about 0.1 percent by weight to about 50 percent by weight, basis the total weight of the composition, of one or more secondary alkyl sulfate compounds.

4. The composition of claim 1 wherein said one or more secondary alkyl sulfate compounds has a formula:

##STR2## wherein R₂ represents an alkyl group having from about 3 to about 18 carbon atoms and R₃ represents an alkyl group having from about 1 to about 6 carbon atoms.

5. The composition of claim 4 wherein said one or more secondary alkyl sulfate compounds is selected from the group consisting of a C₁₂ secondary alkyl sulfate wherein R₂ represents an alkyl group having 10 carbon atoms and R₃ represents an alkyl group having 1 carbon atom, a C₁₄ secondary alkyl sulfate wherein R₂ represents an alkyl group having 12 carbon atoms and R₃ represents an alkyl group having 1 carbon atom, a C₁₆ secondary alkyl sulfate wherein R₂ represents an alkyl group having 14 carbon atoms and R₃ represents an alkyl group having 1 carbon atom, a C₁₈ secondary alkyl sulfate wherein R₂ represents an alkyl group having 16 carbon atoms and R₃ represents an alkyl group having 1 carbon atom, and mixtures of these compounds.

6. The composition of claim 1 wherein the secondary alkyl sulfate compound is added to the composition in the form of a free flowing powder.

7. The composition of claim 1 wherein the secondary alkyl sulfate compound is present in the composition in an amount of from about 1 percent by weight to about 21 percent by weight, basis the total weight of the composition.

12. The composition of claim 1 wherein said composition additionally comprises one or more cosurfactant compounds selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, zwitterionic surfactants, and mixtures thereof.

13. The composition of claim 1 wherein said composition additionally comprises one or more cosurfactant compounds selected from the group consisting of anionic surfactants, nonionic surfactants, and mixtures thereof.

14. The composition of claim 13 wherein said one or more cosurfactant compounds is a nonionic surfactant selected from alcohol ethoxylates having an average of from about 3 to about 14 ethylene oxide units per ethoxylate molecule, alkyl-substituted phenol ethoxylates having an average of from about 3 to about 14 ethylene oxide units per ethoxylate molecule, sugar-derived glycols, and mixtures thereof.

15. The composition of claim 1 wherein said composition additionally comprises from about 0.1 percent by weight to about 12 percent by weight, basis the total weight of the composition, of one or more cosurfactant compounds.

19. The composition of claim 1 wherein said composition comprises from about 0.1 percent by weight to about 99.9 percent by weight, basis the total weight of the composition, of one or more solvents.

2. A liquid hard surface cleaning composition comprising from about 0.1 percent by weight to about 21 percent by weight, basis the total weight of the composition, of one or more secondary alkyl sulfate compounds, and from about 60 percent by weight to about 99.9 percent by weight, basis the total weight of the composition, of one or more solvents.

16. The composition of claim 2 wherein said one or more solvents is selected from the group consisting of water, lower alcohols, polyols, alkali metal aryl sulfonates and mixtures thereof.

17. The composition of claim 16 wherein said one or more solvents comprises a mixture of a lower alcohol, water, and a polyol.

18. The composition of claim 2 wherein said composition comprises from about 70 percent by weight to about 98 percent by weight, basis the total weight of the composition, of one or more solvents.

3. A powdered hard surface cleaning composition comprising from about 0.1 percent by weight to about 50 percent by weight, basis the total weight of the composition, of one or more secondary alkyl sulfate compounds, and from about 25 percent by weight to about 99.9 percent by weight, basis the total weight of the composition, of one or more builders.

8. The composition of claim 3 wherein said one or more builders is selected from the group consisting of alkali metal carbonates, alkali metal phosphates, alkali metal polyphosphates, alkali metal silicates, alkali metal bicarbonates, alkali metal polycarboxylates, polyacrylates and mixtures thereof.

9. The composition of claim 8 wherein said one or more builders is an alkali metal polycarboxylate.

10. The composition of claim 9 wherein said alkali metal polycarboxylate is selected from the group consisting of sodium citrate, potassium citrate, the sodium salt of tartaric acid monosuccinate, the potassium salt of tartaric acid monosuccinate, the sodium salt of tartaric acid disuccinate, the potassium salt of tartaric acid disuccinate, and mixtures thereof.

11. The composition of claim 3 wherein said builder is present in an amount of from about 40 percent by weight to about 95 percent by weight, basis the total weight of the composition.
