Abstract
Abstract Bleach activators are herein disclosed having the stoichiometric formula: [Cu(R1R2CHR5(CH2)nR6CHNR3R4)Xm](I) wherein R1, R2, R3, R4, R5 and R6 are each a radical selected from the group consisting of hydrogen, alkyl, aryl, alkylaryl, arylalkyl, phenyl, benzyl and mixtures thereof, or R5 and R6 together form a hydrogen carbon ring, n is an integer from 0 to 1, m is an integer from 1 to 2, and X is selected from mono- and polyvalent anions. These bleach activators are combined with a peroxygen compound capable of releasing hydrogen perioxide in an aqueous solution. The combination is especially effective in the removal of hydrophobic stains from fabrics.
