They damage colored, silk, and wool fabrics and are therefore limited to use in white laundry.However, despite their historical dominance and low cost, they have some distinct disadvantages: Their low cost and high availability make them affordable in most regions of the world. NaOCl is still the most commonly and widely used bleach in the United States.Īqueous solutions of NaOCl are strong bleaching agents and powerful disinfectants. It has remained virtually unchanged over the years, with only minor improvements in quality that have resulted from better manufacturing techniques. Liquid chlorine bleach, or sodium hypochlorite (NaOCl), was the only household bleach available in the mid-1950s. These are chlorine bleaches, primarily sodium hypochlorite, and peroxygen (oxygen-based) bleaches, including sodium perborate, sodium percarbonate, liquid hydrogen peroxide, and peracid precursors. 1).ĭespite the large amount of research and data that has been generated over several decades and the numerous bleaching agents that have been identified and manufactured, only a few of these agents have made it into consumer household products or gained significant commercial importance. Such regimentation of the laundering process, supported by innovation in laundry prewash and in-wash additives, has significantly boosted laundry detergent industry growth and fueled the need for the development of more effective but safe bleaching actives ( Fig. In recent years, manufacturers have offered a variety of products and regimens for more effective stain removal. They can also be offered as laundry prewash and additives that have been formulated to boost the stain removal efficacy of detergents. Such materials can be included directly in a detergent formulation to remove bleachable stains such as those associated with tea, coffee, red wine, and various fruit and vegetable products. However efficient, modern detergents still cannot remove some stains effectively without the aid of bleaching systems.Ī bleaching system in the context of this article refers to materials that possess useful oxidative properties.

Principal components of detergent formulations such as surfactants, builders, and enzymes remove primarily oily, greasy, particulate, and proteinacious soils and stains.
