Hair bleaching composition comprising a non-volatile liquid branched ester of a carboxylic acid with a solidification point below 4 deg c

The invention provides a combination for bleaching the keratin fiber, comprising at least one peroxidated salt and at least one nonvolatile liquid branched chain ester of carboxylic acid, wherein the freezing point of the branched chain ester is below 4 degree and the branched chain ester is selected from the compound of the following structure (I): R1-CO-O-R2 (I), wherein the R1 and R2 respectively denote C1-C30, preferably C2-C20 hydrocarbon chain, optionally inserting one or more oxygen atoms and/or one or more carbonyl groups and optionally being substituted by one or more hydroxyl groups, R1 is branched chain. The combination for bleaching the keratin fiber has good low temperature resistance and especially can prevent the syneresis during temperature cycling in low temperature storage and transit.
