Abstract
Abstract Bleaching agent activators which function to release active oxygen. The activator is an amidine of the formula: ##STR1## wherein X is hydrogen, a halogen, an alkyl, aryl, alkylaryl, cycloalkyl, thioalkyl, oxylalkyl, acyl, an inorganic acid radical such as SO 3 H, or an organoinorganic radical, R 1 , R 2 and R 3 designate hydrogen, an alkyl, aryl, alkylaryl, cycloalkyl or acyl radical; HA designates an inorganic or organic monoacid or the equivalent part of a polyacid. This class of amidines improves the effectiveness, at regular or moderate temperature, of liquid or solid bleaching agents, such as hydrogen peroxide, alkaline perborates and percarbonates.
