DMD is the most selective non-chlorine bleaching agent known, and reacts with residual lignin in a way similar to chlorine and chlorine dioxide. In particular, DMD has the selectivity equivalent to chlorine dioxide in the bleaching of low-Kappa pulp, for example, a Kappa of less than 7 to 8 units. 2, record 1, English, - dimethyldioxirane

Le DMD est l'agent de blanchiment non chloré le plus sélectif connu à ce jour. Il réagit avec la lignine résiduaire de façon similaire au chlore et au bioxyde de chlore. Le DMD possède une sélectivité équivalente à celle du dioxyde de chlore en ce qui concerne le blanchiment des pâtes de faibles indices kappa (moins de 7-8). 2, record 1, French, - dim%C3%A9thyldioxirane
