Abstract

Alkaline cleaning compositions with a blend of an amine and a nonionic alcohol ethoxylate between about 1:2 to about 1:10, preferably about 1:5 to about 1:10, with an alkalinity source and chelant are provided. The cleaning compositions provide efficacious cleaning of fatty soils to enhance fatty soil removal. Methods of cleaning surfaces using the cleaning composition are also disclosed.

First claim

What is claimed is:

1. A cleaning composition comprising:
from about 0.1 wt-% to about 10 wt-% of an amine, wherein the amine is selected from any one of the following formulas:

wherein R is a linear or branched C12-C16 alkyl group,

wherein R is a linear or branched C21-C30 alkyl group,

wherein R is a linear or branched C21-C30 alkyl group,
R—NH—[(CH 2 ) r NH] y —(CH 2 ) m —NH 2   (2a)

wherein R is a linear or branched C18 alkyl group and wherein m, r, and y independently represent an integer ranging from 1 to 6; or combinations thereof;

from about 0.1 wt-% to about 20 wt-% of a nonionic alcohol ethoxylate surfactant, wherein the alcohol ethoxylate is according to the formula: R—O—(CH 2 CH 2 O) n —H, wherein R is a linear C8-C13 alkyl group and n is an integer from 4 to 6, and wherein optionally the formula comprises a PO group, wherein the weight ratio of the amine to the nonionic alcohol ethoxylate surfactant is from 1:2 to 1:10;
a chelant; and
an alkalinity source.

2. The composition of claim 1 , wherein the weight ratio of the amine to the nonionic alcohol ethoxylate surfactant is from about 1:5 to about 1:10.

3. The composition of claim 1 , wherein the alkalinity source is one of an alkali metal hydroxide, carbonate, borate and/or silicate.

4. The composition of claim 1 , wherein the chelant is an aminocarboxylic acid.

5. The composition of claim 1 , wherein the chelant is a polycarboxylate polymer.

6. The composition of claim 1 , wherein the chelant comprises an aminocarboxylic acid and a polycarboxylate polymer.

7. The composition of claim 1 , further comprising at least one solvent.

8. The composition of claim 1 , further comprising at least one functional ingredient selected from additional surfactants, chelating agents, sequestering agents, detergents, additional alkaline sources, builders, bleaching agents, sanitizers, activators, builders, fillers, defoaming agents, anti-redeposition agents, optical brighteners, dyes, odorants, stabilizing agents, dispersants, enzymes, corrosion inhibitors, thickeners, solubility modifiers, or combinations thereof.

9. A method of cleaning comprising:
contacting a surface with the cleaning composition of claim 1 ; and
removing fatty soils from the surface.

10. The method of claim 9 , wherein the surface is a hard surface.

11. The method of claim 9 , wherein the surface is ceramic, stainless steel and/or polymeric.

12. The method of claim 9 , wherein the surface is an open surface in a food and/or beverage plant.

13. The method of claim 9 , wherein the removal of fatty soils from the surface provides at least about 85% soil removal.

14. The method of claim 9 , wherein the removal of fatty soils from the surface provides at least about 90% soil removal.
