<p>The present invention discloses a process for the manufacture of liquid aqueous bleaching compositions comprising hypochlorite, a strong source of alkalinity and water, said process comprising the steps of: mixing said alkali metal hypochlorite, said strong source of alkalinity and said water, separating the insoluble species formed in said first step, and thereafter adding a chelating agent capable of chelating heavy metal ions. The compositions provided by the process according to the present invention are substantially free of heavy metal ions, thereby providing improved whiteness performance and/or fabric safety performance.</p> |
