Abstract
The invention provides improvements in the color protection properties of detergents and cleaning agents during their utilization for washing or cleaning colored textile fabrics. Specific polycarbonate-, polyurethane- and/or polyurea-polyorganosiloxane compounds or a precursor compound thereof containing specific reactive groups, which can be used for the production of the polycarbonate-, polyurethane- and/or polyurea-polyorganosiloxane compounds, are utilized.
Claims8
A method of preventing the transfer of a textile dye from a dyed textile to an undyed textile or from a first dyed textile to a second dyed textile having a different color than the first dyed textile when washed together in an aqueous solution comprising a surfactant, said method comprising providing the aqueous solution with at least one polycarbonate-polyorganosiloxane compound containing at least one structural element of Formula (I):
- —Y-A-(C═O)-A- (I)
- where each A is O,
- 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, where the carbon atoms of a polyorganosiloxane unit that is optionally also contained are not counted, which may contain one or more groups selected from —O—, —(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 in the entire compound, not all the radicals Y and/or R1 and/or R2 and/or R3 indicated in Formula (I) must be the same, 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
- or an acid addition compound and/or salt thereof.
