Abstract:
Disclosed herein are capsules for delayed release of an active ingredient contained therein, in particular water-soluble capsules for delayed release of water-sensitive, gas-generating compositions into an aqueous liquid medium. The delayed release capsules incorporate one or more gas-relief pinholes for gas-generating water-sensitive compositions contained in the capsules, such as inorganic bleach or other alkaline compositions intended for delayed release into a wash medium during a laundry cycle. The pinholes permit gas generated within the capsule due to exposure to environmental water vapor to escape from the capsule interior, preventing pressure build-up and capsule deformation during storage. The pinholes are sized to prevent or otherwise substantially limit the passage of liquids when submerged in a liquid medium (e.g., liquid water in an aqueous liquid medium). Related articles and methods for delivering the capsules in combination with a detergent or other laundry composition are also disclosed.
