Chemical compound

Sodium nonanoyloxybenzenesulfonate (NOBS) is an important component of detergents and bleaches. It is known as a bleaching activator for active oxygen sources, allowing formulas containing hydrogen peroxide releasing chemicals (specifically the sodium perborate, sodium percarbonate, sodium perphosphate, sodium persulfate, and urea peroxide. Unlike tetraacetylethylenediamine, NOBS can be used in a much lower temperature.
