BLEACHING COMPOSITION COMPRISING NON-VOLATILE LIQUID BRANCHED ESTER OF CARBOXYLIC ACID HAVING COAGULATION POINT LOWER THAN 4°C

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): R1-CO-O-R2(wherein R1and R2each 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 R1is 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.
