ACTIVATED BLEACHING PROCESS AND COMPOSITIONS THEREFOR |
摘要 |
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, cyanamide or a metal cyanamide as peroxide activator, and a Group IIA metal, which acts in conjunction with cyanamide or metal cyanamide to further activate the peroxide-based bleach. Stable concentrated liquid or solid peroxide-based bleach compositions containing cyanamide or a metal cyanamide activator and a Group IIA metal are also disclosed. |
