DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to detergent compositions containing polyamine N-oxide polymers. More in particular, the present invention relates to the use of polyamine N-oxide polymers for removal of pigment stains.
BACKGROUND OF THE INVENTION
For many years detergent compositions have contained chelating agents and/or bleaching agents for removal of pigment stains such as tea, coffee, wine and fruit stains on household laundry.
Chelants react with the heavy metals present in such stains, thereby providing stain removal performance benefits by extraction of the metal ions from the stains.
Phosphorus-containing compounds have proven to be very useful as chelating agents. However, there is a growing concern regarding the use of phosphorus-containing compounds in detergent compositions because such compounds lead to the eutrophication of lakes and streams. This has urged the detergent formulator to restrict the phosphorus content of detergent compositions, necessitating the formulation of laundry detergents containing chelants less effective than the conventionally-used phosphonates or poly-phosphonates. These requirements have complicated the formulation of effective detergent compositions in terms of cleaning efficiency in general and stain removal in particular. It would, therefore, be highly desirable to be able to formulate detergent compositions which include reduced levels of phosphorous-containing components, but which still exhibit excellent cleaning and stain removal performance. It has now been found that certain polyamine-N-oxide polymers are very efficient in removing pigment stains. This finding allows to formulate detergent compositions exhibiting excellent cleaning and stain removal performance.
SUMMARY OF THE INVENTION
The present invention relates to detergent compositions comprising polyamine N-oxide polymers which contain units having the following structure formula: ##STR3## wherein P is a polymerisable unit, whereto the N--O group can be attached to or wherein the N--O group forms part of the polymerisable unit or a combination of both. ##STR4## x is 0 or 1; R are aliphatic, ethoxylated aliphatics, aromatic, heterocyclic or alicyclic groups or any combination thereof whereto the nitrogen of the N--O group can be attached or wherein the nitrogen of the N--O group form part of these groups.
DETAILED DESCRIPTION OF THE INVENTION
The compositions of the present invention comprise as an essential element polyamine N-oxide polymers which contain units having the following structure formula: ##STR5## wherein P is a polymerisable unit, whereto the N--O group can be attached to or wherein the N--O group forms part of the polymerisable unit or a combination of both. ##STR6## x is 0 or 1; R are aliphatic, ethoxylated aliphatics, aromatic, heterocyclic or alicyclic groups or any combination thereof whereto the nitrogen of the N--O group can be attached or wherein the nitrogen of the N--O group is part of these groups.
The N--O group can be represented by the following general structures: ##STR7## wherein R1, R2, R3 are aliphatic groups, aromatic, heterocyclic or alicyclic groups or combinations thereof, x or/and y or/and z is 0 or 1 and wherein the nitrogen of the N--O group can be attached or wherein the nitrogen of the N--O group forms part of these groups.
The N--O group can be part of the polymerisable unit (P) or can be attached to the polymeric backbone or a combination of both.
Suitable polyamine N-oxides wherein the N--O group forms part of the polymerisable unit comprise polyamine N-oxides wherein R is selected from aliphatic, aromatic, alicyclic or heterocyclic groups. One class of said polyamine N-oxides comprises the group of polyamine N-oxides wherein the nitrogen of the N--O group forms part of the R-group. Preferred polyamine N-oxides are those wherein R is a heterocyclic group such as pyrridine, pyrrole, imidazole, pyrrolidine, piperidine, quinoline, acridine and derivatives thereof. Another class of said polyamine N-oxides comprises the group of pol
