Abstract

The invention relates to a fabric treatment composition which comprises a self-crosslinking polymer possessing pendant azetidinium groups. A first aspect of the invention comprises an azetidinium functionalized polymer containing primary or secondary amine groups. Cross-linking reactions between the azetidinium group and primary or secondary amine groups do not form quaternary groups and consequently do not result in a charged, cross-linked polymer. This lack of charge is believed to overcome the problems of stain fixing and dye adsorption. A second aspect of the present invention subsists in an azetidinium functionalized polymer of which the monomers comprise: an amino-acrylate and/or amino-alkacrylate monomer, and, optionally, further non-amino acrylate and/or alkacrylate monomer. A third aspect of the present invention provides a textile treatment composition which comprises an azetidinium functionalized polymer in accordance with the first or second aspect of the invention and a textile compatible carrier.

Claims

1. A fabric treatment composition which comprises an azetidinium functionalised polymer containing secondary amine groups and a textile compatible carrier, wherein the monomers of the polymer comprise:

a) an amino-acrylate and/or amino-alkacrylate monomer, and,

b) optionally, further non-amino acrylate and/or alkacrylate monomers,

and wherein the textile compatible carrier is a detergent active compound or a textile softening or conditioning agent; and

wherein the detergent active compound is selected from soap and non-soap anionic, cationic, nonionic, amphoteric and zwitterionic detergent active compounds, and mixtures thereof; and

wherein the textile softening or conditioning agent is a water-insoluble quaternary ammonium compound.

2. A fabric treatment composition according to claim 1 wherein the concentration of the polymer is such as to give 0.01-1% wt on weight of fabric material being treated.
