The hydrolytic stability of a novel cationic bleach activator, N ‐[4‐(triethylammoniomethyl)benzoyl]capro‐lactam chloride, in aqueous solution has been investigated. After treatment with a bleach system, the whiteness of cotton fabric was measured. Assessment of the available oxygen was used to assess the stability of the bleach activator in solution with respect to time, using a method which minimised the effect of hydrogen peroxide on total available oxygen. Whereas the N ‐[4‐(triethylammoniomethyl)benz‐oyl]caprolactam chloride in solid form was found to be stable, in aqueous solution it was relatively easily hydrolysed. The effect of pH on its stability in solution was assessed. A good correlation was found between change in available oxygen on storage and bleaching performance.
