Low-temperature-stable preservatives
A liquid, cold-temperature-stabilized preservative is based on carbendazim or a salt thereof, which includes, as low-temperature stabilizer, at least one aromatic alcohol and/or at least one aromatic glycol ether and/or a pyrrolidone.
1. A liquid, low-temperature-stabilized preservative comprising carbendazim or a salt thereof and an effective amount of a low-temperature stabilizer comprising at least one aromatic glycol ether.
2. The preservative according to claim 1 , wherein said aromatic glycol ether is a C 6 -C 10 -aryloxy-C 2 -C 6 -alkylene glycol ether.
3. The preservative according to claim 2 , wherein said aryl group is a phenyl group.
4. The preservative according to claim 2 , wherein said alkylene group has 2 or 3 carbon atoms.
5. The preservative according to claim 2 , wherein said preservative comprises at least 2% by weight of said low-temperature stabilizer.
6. The preservative according to claim 2 , wherein said carbendazim or a salt thereof is an alkylbenzenesulphonate salt, where the alkyl group has 6 to 18 carbon atoms.
7. The preservative according to claim 2 , wherein said preservative has at least 5% by weight of said low-temperature stabilizer.
8. The preservative according to claim 2 , further comprising biocidal active ingredients.
9. The preservative according to claim 1 , wherein said aromatic glycol ether is selected from the group consisting of 1-phenoxy-3-propanol, 1-phenoxy-2-propanol, phenoxyethanol, and mixtures thereof.
10. The preservative according to claim 9 , wherein said carbendazim or a salt thereof is an alkylbenzenesulphonate salt, where the alkyl group has 6 to 18 carbon atoms.
11. The preservative according to claim 9 , wherein said preservative has at least 5% by weight of said low-temperature stabilizer.
12. The preservative according to claim 1 , wherein said preservative comprises at least 2% by weight of said low-temperature stabilizer.
13. The preservative according to claim 12 , wherein said aromatic glycol ether is selected from the group consisting of 1-phenoxy-3-propanol, 1-phenoxy-2-propanol, phenoxyethanol, and mixtures thereof.
14. The preservative according to claim 12 , wherein said carbendazim or a salt thereof is an alkylbenzenesulphonate salt, where the alkyl group has 6 to 18 carbon atoms.
15. The preservative according to claim 1 , wherein said carbendazim or a salt thereof is an alkylbenzenesulphonate salt, where the alkyl group has 6 to 18 carbon atoms.
16. The preservative according to claim 15 , wherein said preservative has at least 5% by weight of said low-temperature stabilizer.
17. The preservative according to claim 1 , wherein said preservative has at least 5% by weight of said low-temperature stabilizer.
18. The preservative according to claim 1 , further comprising biocidal active ingredients.
19. A liquid, low-temperature-stabilized preservative comprising:
an amount of carbendazim or a salt thereof; and
an effective amount of one or more aromatic glycol ethers, wherein,
said effective amount stabilizes and reduces precipitation of said carbendazim or a salt thereof during storage.
