Abstract
Abstract This invention relates to bleaching compositions that provide effective and efficient surface bleaching of textiles over a wide range of bleach solution temperatures. The compositions of the invention yield a C 10 -C 15 peroxyacid when used in bleaching compositions with low ionic strength, and which are substantially free of cationic surfactants. In a preferred embodiment, the bleaching compositions of the invention are detergent compositions.
