Abstract
Abstract An article of manufacture is disclosed for cleansing the skin with improved effectiveness. A soft, flexible web having a low density wiping zone works in concert with a lipophilic cleansing emollient to remove soil from the skin with improved effectiveness. The lipophilic cleansing emollient reduces dehydration of the soil and weakens the soil-skin adhesive forces while the low density wiping zone of the web entraps and thus removes the soil from the skin.
