There is provided a perfumed bleaching composition containing: (a) a hydrophobic bleaching system selected from (i) a perhydrate in amount of from 0.1 % to 60 % by weight and combined with a hydrophobic peroxyacid bleach precursor in amount of from 0.1 % to 60 % by weight, (ii) a preformed hydrophobic peroxyacid in amount of from 0.1 % to 60 % by weight, and (iii) mixtures of (i) and (ii), wherein a hydrophobic peroxyacid bleach precursor is defined as a compound which produce under perhydrolysis a hydrophobic peroxyacid whose parent carboxylic acid has a critical micelle concentration less than 0.5 moles/litre, and wherein a hydrophobic preformed peroxyacid is defined as a compound whose parent carboxylic acid has a critical micelle concentration less than 0.5 moles/litre, and (b) a perfume composition in amount from 0.05 % to 2 % by weight which comprises one or more aroma chemicals selected from: tertiary alcohols, nitriles, lactones, ketones, acetals, ethers, schiff bases, esters and mixtures thereof, wherein the total sum of the weight of said aroma chemicals in the perfume is at least 40 % by weight of the perfume.
