ABSTRACT:
Detergent compositions, essentially free of peroxygen or chlorine bleach compounds, containing a surfactant, builder, enzyme and from about 0.001% to about 5% by weight polyethyleneimine (PEI) or salts thereof are disclosed. These compositions provide enhanced removal of organic stains, particularly on polyphenolic stains such as morello juice (cherry juice), blueberry juice, red wine, tea and coffee. Improvement was also demonstrated on certain non-polyphenolic stains such as grass.
