Abstract
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.
