Bleaches oxygen transfer agents

This chapter will cover low-temperature bleach activators, catalysts utilizing peroxide or atmospheric oxygen for the oxidation reaction, and oxygen transfer agents that act as performance boosters for common bleach systems. Optimum conditions of use to maximize performance and avoid negative secondary reactions are described. Special attention is given to the various finishing processes, application forms, and delivery concepts that enable sensitive bleach components to be incorporated in household products, improve stain removal performance, and deliver an attractive appearance for consumers. 

Dioxiranes, of which DMD is the simplest member, are powerful electrophilic oxidizing agents, able to transfer oxygen to aromatic rings and double bonds. DMD was identified by Ragauskas [113] and Lee and coworkers [114] as a very effective bleaching agent for chemical pulps. It can be added directly to pulps or prepared in situ from acetone and PMS.
