Claims
- 1. An aqueous isothiazolone formulation consisting essentially of:
- (a) 1-20% by weight of an isothiazolone compound represented by the formula (I): ##STR15## where X represents a hydrogen atom or halogen atom and Y represents an alkyl group,
- (b) water or a mixture of water and a hydrophilic organic solvent in an amount at least sufficient to dissolve the compound of the general formula (I) described above, the amount of water in the formulation being at least 5% by weight; and
- (c) a stabilizing-effective amount, in the range of 0.001 to 0.1 part by weight based on one part by weight of the compound of formula (I), of 2,2-dibromo-2-nitroethanol.
- 2. The formulation of claim 1 in which the isothiazolone compound of the formula (I) is 2-methyl-5-chloro-1,2-isothiazolin-3-one, 2-methyl-1,2-isothiazolin-3-one or mixture thereof.
- 3. The formulation of claim 1 in which the water content is adjusted to be not less than 10% by weight.
- 4. The formulation of claim 1 in which component (b) is a mixture of water and a hydrophilic organic solvent.
- 5. The formulation of claim 4, wherein the hydrophilic organic solvent is selected from the group consisting of ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, polypropylene glycol, 1,4-butanediol, 1-5-pentanediol, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, tripropylene glycol monomethyl ether, N,N-dimethylformamide, N,N-diethylformamide, N,N-dimethylacetamide and N-methyl-2-pyrrolidone.
