Microorganism control agent and stabilizing method
Disclosed is a microorganism control agent containing not less than 1% by weight but less than 10% by weight of N,N′-hexamethylenebis(4-carbamoyl-1-decylpyridinium bromide), not less than 35% by weight but less than 60% by weight of at least one alcohol having 2 or 3 carbon atoms, water and an acid.
1. A microorganism control agent comprising:
not less than 1% by weight but less than 10% by weight of N,N′-hexamethylene bis(4-carbamoyl-1-decylpyridinium bromide);
not less than 35% by weight but less than 60% by weight of at least one monohydric alcohol having either 2 or 3 carbon atoms;
water; and
an acid.
2. The microorganism control agent according to claim 1 , wherein the acid is an edible organic acid.
3. The microorganism control agent according to claim 2 , wherein the edible organic acid is a citric acid.
4. The microorganism control agent according to claim 1 , wherein the acid is contained in a range of 0.1 to 40 mol per 1 mol of N,N′-hexamethylene bis(4-carbamoyl-1-decylpyridinium bromide).
5. The microorganism control agent according to claim 4 , wherein the acid is contained in a range of 0.1 to 10 mol per 1 mol of N,N′-hexamethylene bis(4-carbamoyl-1-decylpyridinium bromide).
6. An N,N′-hexamethylene bis(4-carbamoyl-1-decylpyridinium bromide) stabilizing method comprising
mixing not less than 1% by weight but less than 10% by weight of N,N′-hexamethylene bis(4-carbamoyl-1-decylpyridinium bromide), not less than 35% by weight but less than 60% by weight of at least one monohydric alcohol having either 2 or 3 carbon atoms, water, and an acid.
