System cleaner concentrate
A concentrate for cleaning and disinfecting includes (i) one or more alkyl alcohol alkoxylates, (ii) one or more formaldehyde donor compounds, (iii) optionally one or more biocidal, in particular fungicidal, active ingredient(s), (iv) optionally one or more glycols and (v) optionally up to 10% by weight of water. Concentrates according to the invention can be formulated with a high content of formaldehyde donor compound without an undesired formaldehyde odor arising.
1. A concentrate for cleaning and disinfecting, comprising:
(i) one or more alkyl alcohol alkoxylates,
(ii) 3,3′-methylenebis (5-methyl oxazolidine),
(iii) pyrione sodium,
(iv) one or more glycols, and
(v) optionally up to 10% by weight of water, wherein the concentrate is free from active ingredients of the following classes of compounds: (a) isothiazolone compound, (b) benzimidazole compound, (c) iodopropynyl compound and (d) iodoacetamide and/or thiophene compound.
2. The concentrate according to claim 1 , wherein the alkyl alcohol alkoxylate is derived from linear or branched aliphatic alcohol having 6 to 18 carbon atoms and alkoxylated with up to 20 ethylene oxide, propylene oxide and/or butylene oxide groups.

4. The concentrate according to claim 1 , wherein component (i) is present in an amount of from 2 to 50% by weight.
5. The concentrate according to claim 1 , wherein 3,3′-methylenebis (5-methyl oxazolidine) is present in an amount such that a fraction of formaldehyde which can be cleaved off the 3,3′-methylenebis is in a range of from 2 to 50% by weight.
6. The concentrate according to claim 1 , wherein the pyrione sodium is present in an amount of from 0.1 to 5% by weight.
7. The concentrate according to claim 1 , wherein the one or more glycol is selected from the group consisting of monoethylene glycol, butyl diglycol and 1,2-propylene glycol.
8. The concentrate according to claim 1 , comprising 1,2-propylene glycol in an amount of from 2 to 50% by weight.
9. The concentrate according to claim 1 , comprising butyl diglycol in an amount of from 2 to 50% by weight.
10. The concentrate according to claim 1 , comprising water in a maximum amount of 1% by weight.
11. The concentrate according to claim 1 , wherein component (i) is present in an amount of from 15 to 25% by weight.
12. The concentrate according to claim 1 , wherein the 3,3′-methylenebis (5-methyl oxazolidine) is present in an amount such that a fraction of formaldehyde which can be cleaved off the 3,3′-methylenebis is in a range of from 15 to 25% by weight.
13. The concentrate according to claim 1 , wherein the pyrione sodium is present in an amount of from 0.4 to 0.8% by weight.
14. The concentrate according to claim 1 , comprising 1,2-propylene glycol in an amount of from 15 to 25% by weight.
15. The concentrate according to claim 1 , comprising butyl diglycol in an amount of from 4 to 10% by weight.
16. The concentrate according to claim 1 , comprising at most 5% by weight of water.
