Abstract

The present invention relates to fabric care and laundry detergent compositions which comprise low molecular weight modified and unmodified amines which provide enhanced fabric appearance benefits. The low molecular weight polyamines of the present invention which mitigate fabric damage and improve fabric appearance are preferably polypropyleneimines having three or four backbone amino units.
