Abstract: Activated peroxide systems are formed by adding so-called bleach activators to an aqueous
solution of hydrogen peroxide, developed in the seventies of the last century for use in the domestic
laundry for their high energy efficiency and introduced at the beginning of the 21st century to the textile
industry as an approach toward overcoming the extensive energy consumption in bleaching. In activated
peroxide systems, bleach activators undergo perhydrolysis to generate more kinetically active peracids
that enable bleaching under milder conditions while hydrolysis of bleach activators and decomposition
of peracids may occur as side reactions to weaken the bleaching efficiency. This mini-review aims
to summarize these competitive reactions in activated peroxide systems and their influence on bleaching
performance.
