Abstract: PURPOSE:To obtain a bleaching agent composition which has an excellent bleaching effect, does not cause environmental pollution, and is free from bleaching inhibition, etc., by incorporating a specific nitrile compound as a bleaching activator. CONSTITUTION:A nitrile compound (a) represented by formula I (wherein X is a substituent having a Taft's sigma value of 0.5 or higher) (e.g. formula II or III) is mixed as a bleaching activator with a peroxide, e.g. hydrogen peroxide or sodium percarbonate. Other necessary ingredients such as an inorganic builder (e.g. sodium carbonate) and an organic builder (e.g. an ethylenediaminetetraacetic acid salt) are added to produce the bleaching agent composition. Since the compound (a) reacts with the hydrogen peroxide in an aqueous solution to generate a perimidic acid, which enhances bleaching, a higher bleaching ability than with hydrogen peroxide only is obtained.

Abstract: PURPOSE:To obtain an anionic activator aq. soln. which is stable with time and uniformly transparent by treating the anionic activator aq. soln. in the specified conditions in the presence of a filter aid or an adsorbent of the specified quantity and thereafter filtering the turbidity precipitate. CONSTITUTION:>=0.1wt% filter aid (e.g. diatomaceous filter aid or the like) or an adsorbent is added to an anionic activator aq. soln. (e.g. a metallic salt aq. soln. of alkylarylsulfonate or the like) and the mixture is regulated to 8-10pH and held at >=75 deg.C for >=1hr preferably >=2hr and thereafter filtered by a pressurized filtering method. In this filtered anionic activator aq. soln., a turbidity precipitator is not produced in a long-term preservation and a uniformly transparent liquid is maintained. Still more the conditions such as the addition of the filter aid or the adsorbent, the regulation of pH and the heating at >=75 deg.C may be performed in any order.
