Abstract
Bleaching and detergent compositions are disclosed which upon dissolution in aqueous medium provide a mixture of hydrophobic and cationic peroxyacids. The compositions which are highly effective at removing a wide range of stain types with better background whiteness at bleach solution temperatures of 40.degree. C. and less, comprise a peroxide bleach compound, a hydrophobic peroxyacid (bleach precursor) and a cationic or amphoteric peroxyacid (bleach precursor).
