Detergent compositions, essentially free of chlorine bleach compounds, containing a surfactant, builder, enzyme, peroxygen bleach and from about 0.001% to about 5% by weight polyethyleneimine (PEI) or salts thereof are disclosed. These compositions exhibit controlled and improved bleaching action on stains as well as improved storage stability, fabric safety and whitening/brightening characteristics.

Detergent compositions containing polyethyleneimines for enhanced

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.

Detergent compositions containing polyethyleneimines for enhanced stain

Laundry detergent compositions containing a detergent surfactant, a detergent builder, and from about 0.1% to about 50% by weight ethylene aspartate cysteate sequestrants or its acid form are disclosed. These compositions provide enhanced removal of organic stains, such as food and beverage stains particularly polyphenolic stains such as wine, blueberry, tea, coffee, morello juice and the like.

Detergent compositions containing ethylene aspartate cysteate (EAC)

A process for improving the flowability of compositions containing SCMOS is disclosed which includes employing the salt of SCMOS in intimate admixture with a nonionic glycolipid surfactant as the major SCMOS containing constituent of the composition.

Intimate admixtures of salts of sulfo carboxymethyloxy succinate (SCOMS)

A process for improving the flowability of compositions containing ODS is disclosed which includes employing the salt of ODS in intimate admixture with a nonionic glycolipid surfactant as the major ODS containing constituent of the composition.
