Abstract
The present invention provides detergent compositions, essentially free of peroxygen or chlorine bleach compounds, containing one or more surfactants, one or more builders, one or more enzymes and one or more low MW (e.g., 0.8-25 kDa) polyethyleneimine (PEI) polymers or salts thereof, and methods of producing such compositions. The compositions of the invention provide certain benefits in cleaning of textiles (particularly fabrics including clothing), hard surfaces and dishware and utensils, including enhanced removal of certain difficult-to-remove stains such as chocolate pudding and grass, as well as of polyphenolic stains such as cherry juice, blueberry juice, red wine, tea and coffee. The invention also provides methods of using these compositions in laundry, hard surface cleaning and dishwashing applications.
