Sequential enzyme delivery system

Abstract

A process for fabric washing in which fabric is treated sequentially with at least two different enzymes, the process comprising the steps: 1. treatment with one or more proteases, followed by 2. treatment with one or more of a second enzyme characterised in that the or each second enzyme(s) of the second step is/are of a different enzyme family to the protease(s) in the first step.

1 . A washing machine incorporating a sequential treatment device for sequentially treating fabrics with at least first and second enzymes, the device comprising a plurality of separate chambers containing respectively first and second enzymes, from which chambers the enzymes are sequentially dispensed characterised in that the first enzyme(s) comprise a protease and the second enzyme(s) comprise one or more enzymes of a different family to the first enzyme. 
   
   
       2 . A washing machine according to  claim 1  characterised in that the second enzyme comprises one or more lipolytic enzymes. 
   
   
       3 . The washing machine of  claim 1  wherein the sequential treatment device comprises the drawer of a washing machine.
