ABSTRACT:
A process for the activation of peroxide-based bleaches comprises conjointly incorporating into an aqueous medium a peroxide-based bleach, sufficient buffering agent to maintain the aqueous medium under alkaline conditions and certain metal cyanamides (e.g., calcium cyanamide, disodium cyanamide and sodium acid cyanamide), which have been found to be highly effective peroxide activators when employed under alkaline conditions. Stable concentrated liquid and solid metal cyanamide-activated bleaching compositions are also disclosed.
