Abstract (en)
[origin: WO0050552A1] A method for removing stains from a hydrophobic surface such as plastic, including the steps of applying an aqueous solution of a composition which comprises: (a) from 0.1% to 15% by weight of the composition of an amine oxide, phosphine oxide, sulfoxide or mixtures thereof; (b) from 0.1% to 15% by weight of the composition of one or more low cloud point nonionic surfactants having a cloud point of less than 30 DEG C, selected from ethoxylated-propoxylated alcohol, capped poly(oxyalkylated) alcohols and mixtures thereof, wherein said capped nonionic surfactant is substantially free of dimers and trimers; (c) optionally, an oxygen bleaching agent; (d) optionally, a builder; and (e) adjunct materials, preferably automatic dishwashing detergent adjunct materials selected from the group consisting of enzymes, chelating agents, and mixtures thereof; wherein the weight ratio the nonionic surfactants to the oxide surfactant is within the range of from 25:1 to 1:5; the stains are selected from tomato stains, carotene stains, and mixtures thereof; and wherein the composition prevents redeposition of the stains once it has been removed from the stained surface.
