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.

Claims (35)

1. A hard surface cleaner comprising:

an alkyl polyglycoside in an amount between about 0.1 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 and/or branched alcohol ethoxylate having a carbon chain length between 9 and 12, and

(b) a second nonionic surfactant; and

water in an amount between about 70 wt. % and about 99 wt. %;

wherein the hard surface cleaner is substantially free of alkyl phenol ethoxylates and 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 first nonionic surfactant is a branched alcohol ethoxylate having a carbon chain length of 9, and the second nonionic surfactant is a C9-C16 linear alcohol ethoxylate or a secondary alcohol ethoxylate.

3. The hard surface cleaner of claim 1 , further comprising 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.

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 , further comprising a hydrotrope, a stabilizing agent, or a combination thereof.

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 second nonionic surfactant is a linear alcohol ethoxylate or a secondary alcohol ethoxylate, and the alkyl polyglycoside is an alkyl polyglycoside based on a C8-C14 fatty alcohol.

9. The method of claim 7 , wherein the first nonionic surfactant is a branched alcohol ethoxylate having a carbon chain length of 9.

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. %, an alkalinity source in an amount between about 0.01 wt. % and about 5 wt. %, and a solvent in an amount between about 0.1 wt. % and 15 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; and the 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.

12. A cleaning composition 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 and/or branched alcohol ethoxylate having a carbon chain length between 9 and 12, and

(b) a second nonionic surfactant; and

water in an amount between about 70 wt. % and about 99 wt. %;

wherein the cleaning composition 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.

13. The cleaning composition of claim 12 , wherein the second nonionic surfactant is a C9-C12 linear alcohol ethoxylate; and the alkyl polyglycoside is an alkyl polyglycoside based on a C8-C14 fatty alcohol.

14. The cleaning composition of claim 12 , further comprising a hydrotrope in an amount between about 0.1 wt. % and about 10 wt. %; and a stabilizing agent in an amount between about 0.01 wt. % and about 5 wt. %.

15. The cleaning composition of claim 12 , further comprising an alkalinity source in an amount between about 0.01 wt. % and about 5 wt. %.

16. The cleaning composition of claim 12 , wherein the second nonionic surfactant is a secondary alcohol ethoxylate.

17. The cleaning composition of claim 12 , wherein the first nonionic surfactant is a branched alcohol ethoxylate having a carbon chain length of 9.

18. The cleaning composition of claim 12 , wherein the solvent is in an amount between about 0.5 wt. % to about 5 wt. %.

19. The cleaning composition of claim 14 , wherein the hydrotrope comprises sodium xylene sulfonate; and wherein the stabilizing agent comprises sodium citrate.
