    Abstract: Disclosed herein are capsules for delayed release of an ingredient contained therein, in particular water-soluble capsules for delayed release of water-sensitive, gas-generating compositions, other gas-forming compositions, or other cleaning compositions into an aqueous liquid medium. The delayed release capsules can incorporate one or more gas-relief pinholes for gas-generating water-sensitive or other gas-forming 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 or perfumes. The pinholes permit gas generated or otherwise formed within the capsule, such as 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.

    Abstract: A water-soluble, halogen-resistant film-forming composition useful for packaging water treatment products is disclosed. The film can include an acid-stable, water-soluble polyvinyl alcohol polymer, an oxidizable organic material, a chelating agent, a free radical scavenger, and secondary additives such as plasticizers, lubricants, and surfactants. The resulting film has favorable solubility properties after having been exposed to halogenated (e.g., chlorinated and brominated) compositions such as water treatment and agricultural products for prolonged periods of time.
