Abstract
The invention relates to a detergent which contains a surfactant and optionally further conventional additives of detergents and cleaning agents, the detergent comprising an anti-grey polycarbonate-, polyurethane- and/or polyurea-polyorganosiloxane compound or a precursor compound thereof containing specific reactive groups, which can be used for the production thereof.
Claims11
A detergent comprising 10 wt % to 60 wt % of at least one surfactant comprising an anionic surfactant and at least one polycarbonate-, polyurethane- or polyurea-polyorganosiloxane compound containing at least one structural element of Formula (I):
- —Y-A-(C═O)-A- (I)
- where each A is selected, independently, from S, O or NR1;
- Y is a divalent or polyvalent, linear, cyclic or branched, saturated, unsaturated or aromatic, substituted or unsubstituted hydrocarbon radical with up to 1000 carbon atoms (not counting the carbon atoms of a polyorganosiloxane unit that is optionally also present), which may contain one or more groups selected from —(CO)—, —NH—, —NR2—, —(N+R2R3)— or a polyorganosiloxane unit with 2 to 1000 silicon atoms;
- R1 is hydrogen or a linear, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical with up to 40 carbon atoms, which may contain one or more groups selected from —O—, —(CO)—, —NH— or —NR2—;
- R2 is a linear, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical with up to 40 carbon atoms, which may contain one or more groups selected from —O—, —(CO)— or —NH—;
- R3 is a linear, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical with up to 100 carbon atoms, which may contain one or more groups selected from —O—, —(CO)——or —NH— or is a divalent radical which forms a cyclic structure within the radical Y, or one or both radicals A vicinal to Y together with the radical Y between them may form a heterocyclic radical containing nitrogen,
- and not all the radicals A and/or Y and/or R1 and/or R2 and/or R3 indicated in Formula (I) must be the same in the entire compound, with the provision that at least one of the radicals Y in the entire compound is a polyorganosiloxane unit with 2 to 1000 silicon atoms and/or the acid addition compound and/or salt thereof.
