DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to dye transfer inhibiting compositions containing enzymes. More in particular, this invention relates to dye transfer inhibiting compositions comprising polyamine N-oxide containing polymers and enzymes.
BACKGROUND OF THE INVENTION
Detergent compositions containing enzymes are well known in art. It is equally well recognized that enzyme deactivation occurs in detergent compositions formulated with enzymes. The loss of detergent activity of enzymes is among others depending on the presence of adjunct detergent ingredients.
One type of adjunct detergent ingredient that is added to detergent ingredients 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.
Copending European Patent Application No. 92202168.8 describes polyamine N-oxide containing polymers which are very efficient in eliminating transfer of solubilized or suspended dyes. It has now been surprisingly found that certain polyamine N-oxide polymers provide a stabilizing effect for enzymes formulated in detergent compositions.
In addition to this stabilizing effect, the dye transfer inhibiting performance of the polyamine N-oxide containing polymers are enhanced by the addition of certain type of enzymes. This finding allows to formulate detergent compositions which exhibit excellent dye transfer inhibiting properties while maintaining excellent enzyme activity.
According to another embodiment of this invention a process is also provided for laundering operations involving colored fabrics.
Polymers have been used within detergent compositions to inhibit dye transfer. EP-A-O 102 923 describes the use of carboxyl containing polymers within an aqueous compositions. DE-A-2 814 329 discloses the use of N-vinyl-oxazolidone polymers and FR-A-2 144 721 discloses the use of 15-35% of a copolymer of polyvinylpyrrolidone and acrylic acid nitrile or maleic anhydride within a washing powder. EP-265 257 describes detergent compositions comprising an alkali-metal carboxy-metal carboxymethylcellulose, a vinylpyrrolidone polymer and a polycarboxylate polymer.
SUMMARY OF THE INVENTION
The present invention relates to inhibiting dye transfer compositions comprising 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. ##STR4## R are aliphatic, ethoxylated aliphatic, aromatic, heterocyclic or alicyclic groups 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.
DETAILED DESCRIPTION OF THE INVENTION
The compositions of the present invention comprise as an essential element a polymer selected from polyamine N-oxide containing polymers which contain units having the following structure formula (I): ##STR5## 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. ##STR6## 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.
