Abstract
Abstract Halotriazines of the formula: ##SPC1## Where X represents halogen; and R 1 and R 2 individually represent halogen, hydroxy, mercapto, alkyl, alkenyl, alkoxy, alkylmercapto, aryl, aryloxy, arylmercapto, di-alkoxyphosphinyl or ##EQU1## where R 3 and R 4 individually represent hydrogen, alkyl, alkoxy, cyanoalkyl, hydroxyalkyl, carboxyalkyl, chloroalkyl, alkoxyalkyl, acyloxyalkyl, sulfonalkyl, aryl, haloaryl, sulfoaryl, acylaminoaryl, carbamoylalkyl or arylsulfonyloxyalkyl, or where R 3 and R 4 taken together complete a ring structure selected from morpholine, piperazine, piperdine, succinimide, malemide and phthalimide rings; are bleach activators of high activating strength and good storage stability in peroxygen bleaching compositions.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
114 words
A bleaching composition consisting essentially of hydrogen peroxide or a hydrogen peroxide-releasing compound and an activating amount of a halo-triazine compound represented by the formula: ##SPC6## where X represents chlorine and bromine; and R 1 and R 2 individually represent chlorine, bromine, hydroxy, mercapto, lower alkyl, lower alkoxy, phenoxy, dimethoxyphosphinyl or ##EQU5## where R 3 and R 4 individually represent hydrogen, lower alkyl, lower cyanoalkyl, lower hydroxyalkyl, ethoxyethyl, phenyl, or chlorophenyl, or where R 3 and R 4 taken together complete a ring structure selected from morpholine, piperazine, piperidine, succinimide, maleimide and phthalimide rings wherein the mole ratio of the halo-triazine compound to the hydrogen peroxide-releasing compound is from about 1:1 to about 1:10.
