Description

FIELD OF THE INVENTION

[0001] The present invention is in the field of cleaning compositions.BACKGROUND OF THE INVENTION

[0002] An important purpose of detergents and / or cleaning compositions is to remove soils and stains from fabrics to achieve consumer perceivable cleaning benefit. The ability of a particular detergent or cleaning composition to remove soils and stains is determined not only by the surfactant activity level in the composition, but also by many others factors.

[0003] For example, the wash water used with detergents or cleaning compositions may contain various metal ions (e.g., calcium or magnsium ions) that can chemically combine with surfactants in the wash to form insoluble precipitates, which not only render the surfactant ineffective for soil / stain remval, but also form scums that further soil the fabric surface. Therefore, water with a higher concentration of metal ions (i.e., hard water) presents a particularly challenging wash condition. This challenge is further ...
