Both marketing and use of laundry-cleaning additives continue to increase around the world, due to an increasing realization that these products help satisfy the consumer need to remove stains better and to get alundry cleaner. Detergents, soap bars, and pastes are the primary household products sold for washing laundry throughout the world. However, these products do not fully satisfy all laundry needs. Market research has identified one of the biggest laundry problems as stain removal (1). In Spain, 73percent of those who do household laundry complain that detergents do not remove many stains at normal wash temperatures (2). Similarly in the United States, of those who do laundry, less than 10percent agree that detergent is all that is needed to get wash clean, and more than 90percent encounter difficulty in removing stains. To address the consumer need to remove stains and have cleaner laundry, laundry-cleaning additives are sold throughout the world. Laundry-cleaning additives can be divided into three categories: sodium hypochlorite bleach, color-safe detergent boosters, and soil and stain removers. Laundry-cleaning additives do not include laundry conditioners such as fabric softeners and ironing aids.
