BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a composition and a process for inhibiting dye transfer between fabrics during washing. More in particular, this invention relates to dye transfer inhibiting compositions comprising polyamine N-oxide containing polymers and bleaching agents.
BACKGROUND OF THE INVENTION
Bleaching agents have been commonly used in detergent compositions to assist in stain removal, as well as for whitening of fabrics.
In general, bleaches remove soil and colored stains from fabrics by oxidation to make the soil or stain more soluble, and thus more easily to remove it. Bleaches have also been used to whiten light colored fabrics that have suffered from yellowing over time and use.
The relative ability of the bleaching agent to meet various performance criteria is among others depending on the presence of adjunct detergent ingredients. As a consequence, the detergent formulator is faced with a difficult task of providing detergent compositions which have an excellent overall performance.
One of the types of adjunct detergent ingredients that is added to detergent compositions are dye transfer inhibiting polymers.
Said polymers are added to detergent compositions in order to inhibit the transfer of dyes from colored fabrics onto other fabrics washed therewith. These polymers have the ability to complex or adsorb the fugitive dyes washed out of dyed fabrics before the dyes have the opportunity to become attached to other articles in the wash.
Polymers have been used within detergent compositions to inhibit dye transfer. Copending European Patent Application N.degree. 92202168.8 describes polyamine N-oxide containing polymers which are very efficient in eliminating transfer of solubilized or suspended dyes.
It has now been found that polyamine N-oxide containing polymers are very compatible with bleaching agents. In addition, it has been found that the dye transfer inhibiting performance of the polyamine N-oxide containing polymers has been increased in the presence of bleaching agents.
This finding allows us to formulate detergent compositions which have both excellent dye transfer inhibiting properties and overall detergency performance.
According to another embodiment of this invention a process is also provided for laundering operations involving colored fabrics.
SUMMARY OF THE INVENTION
The present invention relates to inhibiting dye transfer compositions comprising
a) a polymer selected from polyamine N-oxide containing polymers which contain units having the following structure formula (I): ##STR1## 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. ##STR2## 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.
b) a bleaching agent
DETAILED DESCRIPTION OF THE INVENTION
The compositions of the present invention comprise as an essential element polyamine N-oxide containing polymers which contain units having the following structure formula: ##STR3## wherein P is a polymerisable unit, whereto the R-N-O group can be attached to or wherein the R-N-O group forms part of the polymerisable unit or a combination of both. ##STR4## 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: ##STR5## 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 polyme
