  • Patent number: 5914304
    Abstract: Concentrate liquid peroxide compositions, especially bleaching and washing compositions of improved stability are produced in a process in which components incorporated into the liquid composition after blending of peroxide with components including a sequestering agent, are subjected to a presequestration stage. In the presequestration stage the further component is contacted with one or more sequestering agents, especially sequestrants which are capable of sequestering transition metal ions, especially a mixture in which one component is capable of sequestering cobalt and other components are not effective in sequestering cobalt. The invention is of particular value where the further component is a pH modifying solution, especially an alkali.
