Abstract

The invention relates to bleach compositions containing, as the bleach, a hydrophobic peroxyacid which is sterically bulky, so that the smallest cross-sectional area of the peroxyacid, defined by multiplying together the two smallest dimensions of the molecule, is from 30 to 80 .ANG..sup.2. Preferred are peroxyacids containing a tertiary alkyl group, a norbornane ring or an adamantone ring. Such peroxyacids are effective for the bleaching of stains, especially hydrophobic stains, with low accompanying dye damage.
