Abstract

A laundry fluid comprising capsules containing a bleach catalyst and contained in a dispensing device, the dispensing device comprising: a. a reservoir containing the laundry fluid, each of the principal dimensions of the reservoir being greater than the average diameter of the capsules, b. a dispensing outlet in fluid communication with the reservoir and having, in at least one part, a rupture diameter which is less than the average diameter of the capsules; wherein the laundry fluid is dispensed from the reservoir by forcing the laundry fluid to egress via the dispensing outlet, and the passage of capsules through the dispensing outlet ruptures the capsules, thereby releasing the bleach catalyst as the laundry fluid is dispensed.
