Abstract
A solid, essentially anhydrous peroxygen bleaching and sanitizing composition which includes a peroxygen bleaching agent, an activator capable of forming a per-acid in the presence of oxygen, and an essentially anhydrous, non-reactive binding agent. The composition of this invention is stable in high humidity and cleans and sanitizes effectively in warm water as well as in hot water. The binding agent utilized in this invention is essentially anhydrous and non-reactive with oxygen. The melting point of the binding agent is preferably from about 35-85.degree. C., more preferably from about 45-70.degree. C., and most preferably from about 50-60.degree. C. The binding agent is present in the composition at a level of from about 25-65%, preferably from about 30-55%, and more preferably from about 35-45% by weight. In addition to these ingredients, optional functional ingredients can be utilized as necessary for specific cleaning purposes.
