DETAILED DESCRIPTION OF THE INVENTION The invention relates to bleaching compounds which provide alkoxy substituted aromatic peroxyacids of the following general formula: ##STR4## wherein R is an alkyl group with from about 4 to about 8 carbon atoms, preferably about 5 to about 8 carbon atoms, and most preferably about 6 carbon atoms.
The benzene ring may be optionally substituted further as with, e.
g.
, an alkyl group, a chloro or nitro group.
The bleaching compounds of the invention provide effective and efficient surface bleaching of textiles which thereby removes stains and/or soils from the textiles.
The compounds are particularly efficient at removing dingy soils from textiles.
Dingy soils are those that build up on textiles after much usage and washing, and result in a gray or yellow tint on a white textile.
These soils are a blend of particulate and greasy materials.
The compounds of the invention provide effective bleaching over a wide range of temperature (5.
degree.
C.
to 85.
degree.
C.
), a preferred range being from about 30.
degree.
C.
to about 60.
degree.
C.
The compounds of the invention perform surprisingly well under full soil load conditions.
Alkyl substituted aromatic peroxyacids with comparable chain length substitution do not provide effective bleaching in the presence of soil.

No.
4,288,388, McCrudden et al, issued Sept.
8, 1981, both incorporated herein by reference, disclose aromatic peroxyacids for use as bleaching compositions.
They specifically disclose aromatic peroxyacids with a further substitution of the benzene ring.
Lower alkyl groups are described as a possible substitution, methyl being the only group specifically mentioned.
Surprisingly, the C.
sub.
4 -C.
sub.
8 alkoxy substituted aromatic peroxyacids provided highly effective bleaching even in the presence of high soil loads, such as those found in many typical consumer wash loads.
The peroxyacid may be used directly as a bleaching agent
