Patent ID: 8685913

Claim:
A method, wherein the method comprises washing a textile provided with oil- and fat-containing soil with a laundry detergent comprising at least one component selected from the group consisting of bleaching agents, enzymatic agents, water-soluble inorganic builders, water-soluble organic builders, synthetic anionic sulfate surfactants, synthetic anionic sulfonate surfactants, and color transfer inhibitors in the presence of at least one polycarbonate-, polyurethane- and/or polyurea-polyorganosiloxane compound, comprising at least one structural element of Formula (I): â€”Y-A-(Câ•O)-A-â€ƒâ€ƒ(I), wherein each A is independently selected from S, O or NR 1 , Y is a di- or polysubstituted, straight chain, cyclic or branched, saturated, unsaturated or aromatic substituted or unsubstituted hydrocarbon group containing up to 1000 carbon atoms not counting the carbon atoms of an optionally comprised polyorganosiloxane unit which can comprise one or more groups, selected from â€”Oâ€”, â€”(CO)â€”, â€”NHâ€”, â€”NR 2 â€”, â€”(N + R 2 R 3 )â€” or a polyorganosiloxane unit containing 2 to 1000 silicon atoms, wherein at least one of the Y units according to the structural element of Formula (I) possesses an â€”(N+R 2 R 3 )â€” grouping, R 1 is hydrogen or a straight chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon group containing up to 40 carbon atoms which can comprise one or more groups, selected from â€”Oâ€”, â€”(CO)â€”, â€”NHâ€” or â€”NR 2 â€”, R 2 is a straight chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon group containing up to 40 carbon atoms which can comprise one or more groups selected from â€”Oâ€”, â€”(CO)â€” or â€”NHâ€”, R 3 is a straight chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon group containing up to 100 carbon atoms which can comprise one or more groups, selected from â€”Oâ€”, â€”(CO)â€”or â€”NHâ€”, or is a divalent group that forms a cyclic structure within the Y group, or one or both A groups neighboring Y can form a nitrogen-containing heterocyclic group with the group Y located between them, and in the overall compound not all of the groups A or Y or R 1 or R 2 or R 3 listed in Formula (I) have to be the same, with the proviso that in the overall compound at least one of the groups Y comprises a polyorganosiloxane unit having 2 to 1000 silicon atoms, and/or an acid addition compound and/or salt thereof, whereby the primary washing power of the laundry detergent is enhanced by the at least one polycarbonate-, polyurethane and/or polyurea-polyorganosiloxane compound and/or acid addition compound and/or salt thereof.
