Abstract

The present invention relates generally to cleaning compositions and, more specifically, to cleaning compositions containing a polyetheramine that is suitable for removal of stains from soiled materials.

First claim

What is claimed is:

1. A method of pretreating or treating a soiled fabric, the method comprising the step of contacting the soiled fabric with a cleaning composition,
the cleaning composition comprising:
from about 1% to about 70% by weight of a surfactant, wherein said surfactant comprises one or more surfactants selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants, and amphoteric surfactants; and
from about 0.1% to about 10% of a polyetheramine of Formula (I):

wherein each of R 1 -R 6 is independently selected from H, alkyl, cycloalkyl, aryl, alkylaryl, or arylalkyl, wherein at least one of R 1 -R 6 is different from H,
each of A 1 -A 6 is independently selected from linear or branched alkylenes having 2 to 18 carbon atoms, each of Z 1 -Z 2 is independently selected from OH, CH 2 CH 2 CH 2 NH 2 , NH 2 , NHR′, or NR′R″, where the degree of amination is from about 10% to less than 50%, where R′ and R″ are independently selected from alkylenes having 2 to 6 carbon atoms, wherein the sum of x+y is in the range of about 2 to about 200, wherein x≥1 and y≥1 and the sum of x 1 +y 1 is in the range of about 2 to about 200, wherein x 1 ≥1 and y 1 ≥1.

2. The method of claim 1 , wherein in said polyetheramine of Formula (I), the degree of amination is in the range of about 30% to less than 50%.

3. The method of claim 1 , wherein in said polyetheramine of Formula (I), x+y is in the range of about 2 to about 20 and x 1 +y 1 is in the range of about 2 to about 20.

4. The method of claim 1 , wherein in said polyetheramine of Formula (I), x+y is in the range of about 3 to about 20 and x 1 +y 1 is in the range of about 3 to about 20.

5. The method of claim 1 , wherein said polyetheramine comprises a polyetheramine mixture comprising at least 90%, by weight of said polyetheramine mixture, of said polyetheramine of Formula (I).

6. The method of claim 1 , wherein in said polyetheramine of Formula (I), each of A 1 -A 6 is independently selected from ethylene, propylene, or butylene.

7. The method of claim 1 , wherein in said polyetheramine of Formula (I), each of A 1 -A 6 is propylene.

8. The method of claim 1 , wherein in said polyetheramine of Formula (I), each of R 1 , R 2 , R 5 , and R6, is H and each of R 3 and R 4 is independently selected from C1-C16 alkyl or aryl.

9. The method of claim 1 , wherein in said polyetheramine of Formula (I), each of R 1 , R 2 , R 5 , and R 6 is H and each of R 3 and R 4 is independently selected from a butyl group, an ethyl group, a methyl group, a propyl group, or a phenyl group.

10. The method of claim 1 , wherein in said polyetheramine of Formula (I), each of R 1 and R 2 , is H and each of R 3 , R 4 , R 5 , and R 6 is independently selected from an ethyl group, a methyl group, a propyl group, a butyl group, a phenyl group, or H.

11. The method of claim 1 , wherein in said polyetheramine of Formula (I), each of R 3 and R 9 is an ethyl group, each of R 4 and R 10 is a butyl group, and each of R 1 , R 2 , R 5 , R 6 , R 7 , R 8 , R 11 , and R 12 is H.

12. The method of claim 1 , wherein said polyetheramine has a weight average molecular weight of about 290 to about 1000 grams/mole.

13. The method of claim 1 , wherein said polyetheramine has a weight average molecular weight of about 300 to about 450 grams/mole.

14. The method of claim 1 , further comprising from about 0.001% to about 1% by weight of enzyme.

15. The method of claim 14 , wherein said enzyme is selected from lipase, amylase, protease, mannanase, or combinations thereof.

16. The method of claim 1 , wherein said surfactant comprises anionic surfactants.

17. The method of claim 16 , wherein said anionic surfactant comprises ethoxylated alkyl sulfate surfactant, non-alkoxylated alkyl sulfate, linear alkyl benzene sulphonate, or mixtures thereof.

18. The method of claim 1 , wherein the cleaning composition is dissolved or dispersed in water to form a wash liquor.

19. The method of claim 18 , wherein the wash liquor has a temperature of from about 0° C. to about 20° C.

20. The method of claim 1 , wherein the soiled fabric comprises a grease stain.
