Abstract:
A granulated bleaching activator comprises: a bleaching activator and at least one nonionic surfactant selected from a nonionic surfactant and an alkylene oxide-added nonionic surfactant both having a melting point less than 20 [deg]C. A granulated bleaching activator comprises (wt.%): a bleaching activator (a) (30 - 96) and at least nonionic surfactant (b) (1-10) selected from a nonionic surfactant (b1) having a melting point less than 20[deg]C and an alkylene oxide-added non ionic surfactant (b2) having a melting point less than 20C. (b1) fulfills the following requirements: when (a) (0.1 g) is added to an aqueous solution produced by dissolving 10 g and 0.25 g of (b1) in water (500 ml) at 10[deg]C and stirring the mixture for five minutes, the solubility of (a) just after the stirring is at least 50 wt.% and not more than 20 wt.% for 10 g and 25 g of (b1) respectively. Independent claims are also included for the following: (1) a bleaching agent comprising the granulated bleaching activator and an inorganic peroxide; and (2) activating the bleaching agent with the granulated bleaching activator.
Abstract:
A foamy composition for bleaching an article of clothing which comprises a liquid composition containing (a) hydrogen peroxide, (b) a specific saccharide derivative based surfactant, (c) a polyoxyalkylene alkyl ether having an alkyl group of 10 to 14 carbon atoms and an average added oxyalkylene mole number of 7 to 12, and (d) water in a specific ratio; and a method for bleaching an article of clothing which comprises contacting the article of clothing with a foam formed from the above liquid composition. The use of the liquid composition in the form of a foam exhibits excellent bleaching effect.
