 Sodium nonanoyloxybenzenesulfonate

Sodium nonanoyloxybenzenesulfonate (NOBS) is an important component of laundry detergents and bleaches.It is known as a bleach activator for active oxygen sources, allowing formulas containing hydrogen peroxide releasing chemicals (specifically sodium perborate, sodium percarbonate, sodium perphosphate, sodium persulfate, and urea peroxide) to effect bleaching at lower temperatures.
