Abstract
The invention relates to machine dishwashing agents containing specific polycarbonate-, polyurethane-, and/or polyurea-polyorganosiloxane compounds or precursor compounds thereof of the reactive cyclic carbonate and urea type which help to avoid the formation of water spots and filming after the use of the agents and accelerate the drying of dishes.
Claims21
An automatic dishwashing agent, comprising:
- a. 0.5 to 3 wt % at least one polycarbonate-, polyurethane- and/or polyurea-polyorganosiloxane compound, comprising at least one structural element of Formula (I):
- —Y-A-(C═O)-A- (I)
- where each A is selected, independently, from S, O and 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 —O—, —(CO)—, —NH—, —NR2—, —(N+R2R3)— and 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— and —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)— and —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)— and —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) within the entire compound 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;
- b. up to 60 wt % phosphate or 15 to 45 wt % citrate;
- c. 2 to 8 wt % nonionic surfactant(s);
- d. 4 to 16 wt % polymer(s);
- e. 2 to 15 wt % sodium percarbonate;
- and
- f. 1 to 6 wt % enzyme(s).

An automatic dishwashing agent, wherein the agent comprises:
- a) 5 wt % to 60 wt % citrate and is phosphate-free or 15 wt % to 25 wt % phosphate;
- and
- b) at least one polycarbonate-, polyurethane- and/or polyurea-polyorganosiloxane compound, comprising at least one structural element of Formula (I):
- —Y-A-(C═O)-A- (I)
- where each A is selected, independently, from S, O and 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 —O—, —(CO)—, —NH—, —NR2—, —(N+R2R3)— and 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— and —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)— and —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)— and —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) within the entire compound 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.
