Abstract
A transparent, durable container for housing and delivering a free-flowing granular dry oxidant bleach composition, the container being constructed of a heteropolymeric plastic which maximizes transmission of water vapor for minimum decomposition of the oxidant bleach stored within the container. The selected plastic has a water vapor transmission rate of at least about 2 g/day/100 in..sup.2 /mil. thickness. The container may include a fragrancing means located remote from the container. The fragrancing means is isolated from the bleach composition by an apertured barrier which allows the fragrance to contact the bleach composition but does not allow the bleach composition to contact the fragrancing means.
