Abstract

The invention meets the needs above by providing a surfactant system, mixture or blend that can be used as a part of a soaking composition. The surfactant system is capable of forming emulsions with, and thus removing, oily and greasy stains. In a preferred embodiment the surfactant compositions of the invention can remove non-trans fat and fatty acid stains. The invention involves foaming soaking compositions that have some or part of the anionic surfactant present in the same replaced with an extended chain anionic surfactant.

Claims (27)

1. A cleaning composition comprising:

from about 0.01 wt. % to about 5 wt. % of a positively charged (PEI) polymer;

a detersive amount of one or more an anionic surfactants, said anionic surfactant including from about 0.48 wt. % to about 4.8 wt. % of an extended chain anionic surfactant of the formula:

R-[L] x -[O—CH 2 —CH 2 ] y -M

where R is a linear or branched, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic hydrocarbon radical having from about 6 to 20 carbon atoms, L is a linking group, wherein said linking group has greater than 5 moles of propoxylation, M is an ionic species, wherein the ionic species comprises carboxylates, sulfonates, sulfates, phosphates, or combination thereof, x is the chain length of the linking group ranging from 6-16, and y is the average degree of ethoxylation ranging from 1 to 5; and

a carrier, wherein said composition has less than 1wt. % cocamide diethanolamine (DEA).

2. The cleaning composition of claim 1 , said composition having less than 0.5 wt. % of cocamide diethanolamine (DEA).

3. The cleaning composition of claim 1 wherein said PEI polymer is an ethoxylated PEI polymer.

4. The cleaning composition of claim 1 wherein said one or more anionic surfactants is present in an amount of from about 1 wt. % to about 75 wt. %.

5. The cleaning composition of claim 1 further comprising a nonionic surfactant in an amount of from about 0.01 wt. % to about 20 wt. %.

6. The cleaning composition of claim 5 wherein said nonionic surfactant comprises lauryl dimethylamine oxide.

7. A cleaning composition comprising:

(a) from about 0.01 wt. % to about 5 wt. % of a positively charged polymer selected from the group consisting of: polyamines, polyquats, polyglycerol quats, ethoxylated PEI, propoxylated PEI, or a mixture of PEI and glycol, or PEI with PO-blocked EO units added to the PEI/glycol mixture;

(b) from about 1 wt. % to about 75 wt. % of an anionic surfactant, or a mixture thereof, said anionic surfactant including from about 0.48 wt. % to about 4.8 wt. % of an extended chain anionic surfactant, wherein said extended surfactant has a formula:

R-[L] x -[O—CH2-CH2 ]y -M

where R is a linear or branched, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic hydrocarbon radical having from about 6 to 20 carbon atoms, L is a linking group wherein said linking group has great than 5 moles of propoxylation, M is any ionic species, wherein the ionic species comprises a carboxylates, sulfonates, sulfates, and phosphates, or combination thereof, x is the chain length of the linking group ranging from 6-16, and y is the average degree of ethoxylation ranging from 1 to 5; and

(c) said composition having less than 0.5 wt. % of cocamide DEA.

8. The cleaning composition of claim 7 wherein said positively charges polymer is an ethoxylated PEI.

9. The cleaning composition of claim 7 , further comprising an anionic surfactant including one or more of sodium C 14 -C 16 olefin sulfonate or sodium lauryl ether ethoxy sulfate.

10. The cleaning composition of claim 1 wherein said PEI is present in an amount of from about 1 wt. % to about 5 wt. %.

11. The cleaning composition of claim 1 wherein said one or more anionic surfactants is present in an amount of from about 5 wt. % to about 65 wt. %.

12. The cleaning composition of claim 1 wherein said carrier is present in an amount of from about 20 wt. % to about 80 wt. %.

13. The cleaning composition of claim 1 further comprising a hydrotrope in an amount between about 0.01 wt. % and about 20 wt. %.

14. The cleaning composition of claim 7 wherein said polymer is present in an amount of from about 1 wt. % to about 5 wt. %.

15. The cleaning composition of claim 7 wherein said anionic surfactants is present in an amount of from about 5 wt. % to about 65 wt. %.

16. The cleaning composition of claim 7 further comprising a carrier in an amount of from about 10 wt. % to about 90 wt. %.

17. The cleaning composition of claim 7 further comprising a hydrotrope in an amount between about 0.01 wt. % and about 20 wt. %.
