    摘要： A process for making a coated bleach component which may be incorporated into a detergent composition comprising hydrogen peroxide solution. The process includes the steps of dispersing the bleach component in a continuous liquid phase to form discrete islands of dispersed phase and subsequently forming a polymeric coating at the interface between the dispersed phase and the continuous phase. The coating formed is resistant to hydrogen peroxide solution and is removable when the liquid continuous phase is diluted with aqueous wash liquor. In this way particulate material which reacts with hydrogen peroxide can be incorporated into an aqueous detergent liquid which contains dissolved hydrogen peroxide, whilst maintaining stability.

    摘要： A liquid concentrate peroxide composition contains a combination of sequestrants which together are capable of universal sequestration of transition metal ions which would otherwise cause decomposition of the peroxide. The combination preferably includes a sequestrant capable of sequestering cobalt and a sequestrant capable of sequestering transition metal ions other than cobalt. A particularly preferred combination includes a poly(methylene phosphonic acid) and nitrogen-donor type sequestrants such as dipyridylamine or triazacyclononane.

    摘要翻译： 一种制备可以掺入含有过氧化氢溶液的洗涤剂组合物中的涂布漂白剂组分的方法。 该方法包括将漂白组分分散在连续液相中以形成分散相的离散岛并随后在分散相和连续相之间的界面处形成聚合物涂层的步骤。 所形成的涂层耐过氧化氢溶液，并且当液体连续相用含水洗涤液稀释时可被除去。 以这种方式，可以将与过氧化氢反应的颗粒材料加入含有溶解的过氧化氢的含水洗涤剂液体中，同时保持稳定性。

    摘要： This invention relates to a process for releasably encapsulating an active substrate which comprises inter alia a bleach activator in a metal salt of an inorganic acid, said salt being soluble in an aqueous medium such that when the encapsulated active substrate is brought into contact with the aqueous medium, the active substrate is released into said medium. This invention is useful for the controlled release of bleach activators into a wash cycle and to stabilise some bleach activators which may otherwise lack stability.

    摘要： A process for the bleaching of cellulosic fibres comprising the steps of (a) providing a water supply; (b) adding hydrogen peroxide to the stabilised water supply to form a hydrogen peroxide solution; (c) adjusting the pH of the hydrogen peroxide solution by adding alkali; mixing the pH adjusted solution resulting from step (c) to allow complete formation of perhydroxyl ion; (e) adding a carboxylic acid anhydride compound to the solution resulting from step (d); (f) mixing the solution resulting from step (e) to allow complete formation of percarboxylic acid to give a dilute solution of percarboxylic acid; and (g) contacting the solution with a suspension of cellulosic fibres.
