PROBLEM TO BE SOLVED: To provide a bleaching composition for keratin fibers capable of avoiding a syneresis problem during the transportation involving the occurrence of temperature cycles and during low-temperature storage. SOLUTION: The bleaching composition for keratin fibers comprises at least one peroxide salt and at least one non-volatile liquid branched ester of a carboxylic acid, in which the coagulation point of the non-volatile liquid branched ester of a carboxylic acid is lower than 4°C, and the ester is represented by formula (I): R<SB>1</SB>-CO-O-R<SB>2</SB>(wherein R<SB>1</SB>and R<SB>2</SB>each independently represent 1-30C, preferably 2-20C hydrocarbon chain which is optionally intervened with one or more oxygen atoms and/or one or more carboxyl groups, or optionally substituted with one or more hydroxyl groups, and R<SB>1</SB>is branched). The bleaching composition for keratin fibers exhibits improved low temperature resistance, and especially is capable of avoiding a syneresis problem during the transportation involving the occurrence of temperature cycles and during low-temperature storage.
