Abstract

Cleaning compositions that include a non-functionalized alkyl polyglycoside, a nonionic surfactant system, and water. In certain embodiments, the cleaning compositions are substantially free of alkyl phenol ethoxylates. Additionally, some embodiments of the invention are substantially free of butyl cellosolve. The cleaning composition is capable of removing both proteinaceous food soils and hydrocarbon-based oily soils. The cleaning compositions include a biorenewable, environmentally friendly alternative to nonyl phenol ethoxylates and exhibit superior cleaning of food soils.

First claim

What is claimed is:

1. A hard surface cleaner comprising:
an alkyl polyglycoside in an amount between about 0.05 wt. % and about 10 wt. %;
a water conditioning agent in an amount between about 0.5 wt. % and about 8 wt. %;
a nonionic surfactant system in an amount between about 0.1 wt. % and about 15 wt. %, wherein said nonionic surfactant system comprises:
(a) a first nonionic surfactant that is a linear alcohol ethoxylate blend wherein at least 70% of the linear alcohol ethoxylates have a carbon chain length of 9, and
(b) a second nonionic surfactant selected from the group consisting of a C9-C12 linear alcohol ethoxylate blend and a secondary alcohol ethoxylate;

a hydrotrope in an amount between about 0.1 wt. % and about 10 wt. %;
a stabilizing agent in an amount between about 0.01 wt. % and about 5 wt. %;
a solvent in an amount between about 0.1 wt. % and 15 wt. %; wherein the solvent comprises one or more of the following: a lower alkanol, a lower alkyl ether, a glycol, an aryl glycol ether, a lower alkyl glycol ether, a glycerol ketal, an ester, a hydrocarbon/ester blend, and a dibasic ester; and
water in an amount between about 70 wt. % and about 99 wt. %;
wherein the hard surface cleaner contains less than 0.5 wt. % alkyl phenol ethoxylates and less than 0.5 wt. % butyl cellosolve, and wherein the composition has efficacy against both proteinaceous food soils and hydrocarbon-based oily soils.

2. The hard surface cleaner of claim 1 , wherein the second nonionic surfactant is a C9-C12 linear alcohol ethoxylate.

3. The hard surface cleaner of claim 1 , wherein the second nonionic surfactant is a secondary alcohol ethoxylate.

4. The hard surface cleaner of claim 1 , wherein the alkyl polyglycoside is an alkyl polyglucoside based on a C8-C14 fatty alcohol.

5. The hard surface cleaner of claim 1 , further comprising an alkalinity source in an amount between about 0.01 wt. % and about 5 wt. %.

6. The hard surface cleaner of claim 1 , wherein the water conditioning agent comprises an aminocarboxylate, wherein the hydrotrope comprises sodium xylene sulfonate, and wherein the stabilizing agent comprises sodium citrate.

7. A method of removing soils from a surface, the method comprising:
contacting a soiled surface with a use solution, wherein the use solution is prepared from the composition of claim 1 , and wherein the surface is soiled with a proteinaceous food soil, hydrocarbon-based oily soil, or combination thereof,
rinsing the surface.

8. The method of claim 7 , wherein the alkyl polyglycoside is an alkyl polyglycoside based on a C8-C14 fatty alcohol.

9. The method of claim 7 , wherein the linear alcohol ethoxylate is a blend where at least 90% of the linear alcohol ethoxylates having a carbon chain length of 9 and about 6 moles of ethoxylate.

10. The method of claim 7 , further comprising one or more of the following: a hydrotrope in an amount between about 0.1 wt. % and about 10 wt. %, a stabilizing agent in an amount between about 0.01 wt. % and about 5 wt. %, and an alkalinity source in an amount between about 0.01 wt. % and about 5 wt. %.

11. The method of claim 10 , wherein the water conditioning agent comprises an aminocarboxylate; the hydrotrope comprises sodium xylene sulfonate; the stabilizing agent comprises sodium citrate.

12. The hard surface cleaner of claim 1 , wherein the linear alkyl ethoxylate is a blend and at least 90% of the linear alcohol ethoxylates having a carbon chain length of 9 and about 6 moles of ethoxylate.

13. A hard surface cleaner comprising:
an alkyl polyglycoside in an amount between about 0.05 wt. % and about 10 wt. %;
a water conditioning agent in an amount between about 0.5 wt. % and about 8 wt. %, wherein the water conditioning agent comprises an aminocarboxylate;
a nonionic surfactant system in an amount between about 0.1 wt. % and about 15 wt. %, wherein said nonionic surfactant system comprises:
(a) a first nonionic surfactant that is a linear alcohol ethoxylate blend wherein at least 70% of the linear alcohol ethoxylates have a carbon chain length of 9, and
(b) a second nonionic surfactant selected from the group consisting of a C9-C12 linear alcohol ethoxylate blend and a secondary alcohol ethoxylate;

a hydrotrope in an amount between about 0.1 wt. % and about 10 wt. %, wherein the hydrotrope comprises sodium xylene sulfonate;
a stabilizing agent in an amount between about 0.01 wt. % and about 5 wt. %, wherein the stabilizing agent comprises sodium citrate; and
water in an amount between about 70 wt. % and about 99 wt. %;
wherein the hard surface cleaner contains less than 0.5 wt. % alkyl phenol ethoxylates and less than 0.5 wt. % butyl cellosolve, and wherein the composition has efficacy against both proteinaceous food soils and hydrocarbon-based oily soils.

14. The hard surface cleaner of claim 13 , wherein the second nonionic surfactant is a C9-C12 linear alcohol ethoxylate.

15. The hard surface cleaner of claim 13 , wherein the alkyl polyglycoside is an alkyl polyglucoside based on a C8-C14 fatty alcohol.

16. The hard surface cleaner of claim 13 , further comprising an alkalinity source in an amount between about 0.01 wt. % and about 5 wt. %.

17. The hard surface cleaner of claim 13 , wherein the second nonionic surfactant is a secondary alcohol ethoxylate.

18. The hard surface cleaner of claim 13 , wherein the linear alkyl ethoxylate is a blend and at least 90% of the linear alcohol ethoxylates having a carbon chain length of 9 and about 6 moles of ethoxylate.

19. The hard surface cleaner of claim 13 , further comprising a solvent in an amount between about 0.1 wt. % and 15 wt. %.

20. The hard surface cleaner of claim 19 , wherein the solvent is in an amount between about 0.5 wt. % to about 5 wt. % and comprises one or more of the following: a lower alkanol, a lower alkyl ether, a glycol, an aryl glycol ether, a lower alkyl glycol ether, a glycerol ketal, an ester, a hydrocarbon/ester blend, and a dibasic ester.
