A microbicide composition comprising:
- (A) 5-chloro-2-methyl-4-isothiazolin-3-one;
- (B) 2,2,6,6-tetramethylpiperidin-1-oxyl;
- and (C) at least one solvent selected from the group consisting of water and a hydrophilic organic solvent,
- wherein the component (A) has a content of from 0.0005 to 13 mass %, the component (B) has a content of from 0.000005 to 1.5 mass %, and the component (C) has a content of from 70 to 99.9995 mass %.
A stabilizer for a composition comprising 5-chloro-2-methyl-4-isothiazolin-3-one and at least one solvent selected from the group consisting of water and a hydrophilic organic solvent, the stabilizer comprising 2,2,6,6-tetramethylpiperidin-1-oxyl as an active ingredient,
- wherein the 5-chloro-2-methyl-4-isothiazolin-3-one has a content of from 0.0005 to 13 mass %, the 2,2,6,6-tetramethylpiperidin-1-oxyl has a content of from 0.000005 to 1.5 mass %, and the at least one solvent has a content of from 70 to 99.9995 mass %.
A method for stabilizing a composition comprising 5-chloro-2-methyl-4-isothiazolin-3-one and at least one solvent selected from the group consisting of water and a hydrophilic organic solvent, the method comprising adding 2,2,6,6-tetramethylpiperidin-1-oxyl to the composition,
- wherein the 5-chloro-2-methyl-4-isothiazolin-3-one has a content of from 0.0005 to 13 mass %, the 2,2,6,6-tetramethylpiperidin-1-oxyl has a content of from 0.000005 to 1.5 mass %, and the at least one solvent has a content of from 70 to 99.9995 mass %.
