<p>A method of laundering fabric onto which a cationic fabric softening active has been deposited and dried comprising the step of contacting the fabric with an aqueous wash liquor having the following composition:
a) 15 to 600 ppm non-soap surfactant,
b) at least 50 ppm ethoxylated polyethylene imine,
c) at least 25 ppm polyester soil release polymer,
the total level of polymer (b+ c) being at least 20 wt% of the level of non soap surfactant (a),
d) 0.1 to 100 ppm enzyme selected from protease, amylase, cellulase,
e) optionally, lipase enzyme.</p> |
