Abstract
Laundry detergent compositions containing a detergent surfactant, a detergent builder, and from about 0.1% to about 10% by weight ethylenediamine-N,N'-disuccinic acid or salts thereof are disclosed. These compositions provide enhanced removal of organic stains, such as food and beverage stains.
