Bleach is a substance used to remove the color from materials such as textiles and paper. Most bleaches act by oxidizing the pigment. Chlorine, or compounds such as calcium and sodium hypochlorites, are commonly used. Other oxidizing bleaches are hydrogen peroxide, used for hair, and sodium perborate. For some applications reducing agents, such as sulfur dioxide, are employed. See also bleaching.
