Abstract (en)
[origin: WO2009040175A1] The invention relates to a method of conferring an improved whiteness benefit to a white textile article during a laundry process, comprising the steps of: a) provision of an aqueous liquor comprising a laundry treatment composition which comprises a florescent whitening agent and an active agent, and, b) contacting the white textile article with the aqueous liquor of (a); characterised in that the active agent comprises: i) a transition metal cation sequestrant; and, ii) a dispersant which comprises one or more of naphthalene sulphonate-formaldehyde condensates, acrylic polymers, sulphonated styrene/maleic anhydride copolymers or a mixture thereof; and, that the white textile article is first contacted with the laundry treatment composition comprising the active agent during a wash step, and is further contacted with active agent made available from a different and separate rinse-added laundry treatment composition.
