Abstract (en)
[origin: US4451384A] Bleaching agent activators which function to release active oxygen. The activator is an amidine of the formula: <IMAGE> wherein X is hydrogen, a halogen, an alkyl, aryl, alkylaryl, cycloalkyl, thioalkyl, oxylalkyl, acyl, an inorganic acid radical such as SO3H, or an organoinorganic radical, R1, R2 and R3 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.
