Abstract:
Disclosed herein are fluorescent tracer compositions and water-soluble polymer compositions containing fluorescent compounds for tracing one or more components in the polymer compositions. More particularly, the disclosure relates to fluorescent tracer compositions including a fluorophore and a bitterant aversive component to be incorporated into a water-soluble polymer composition such as a water-soluble film. An aversive compound such as a bitterant is desirably incorporated into the polymer composition as a deterrent to ingestion of the polymer composition (or an article made therefrom). Qualitative or quantitative detection of the fluorophore in the polymer composition can be correlated to a qualitative or quantitative detection of a corresponding traced material in the polymer composition, for example the bitterant aversive component. Related articles and methods for making and using the polymer compositions are also disclosed.

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.
Abstract:
Disclosed is a pouch having at least one sealed compartment containing a first composition. At least one wall of the at least one sealed compartment is made from a water-soluble film having any suitable thickness. The water-soluble film comprises PVOH polymer such that when the film has a thickness of about 76 microns the film is characterized by a Dissolution Index of about 620 to about 920, or of about 665 to about 920, or about 710 to about 920; and a Stress Index of about 145 to about 626, or about 155 to about 480, or about 165 to about 325.
Abstract:
Disclosed herein are water-soluble films and resulting packets including a water soluble film, wherein the water-soluble film includes a water-soluble mixture of polyvinyl alcohol, a compatibilizing agent, and a sugar alcohol plasticizer that is a solid at room temperature, wherein the water-soluble film is substantially transparent.
Abstract:
Disclosed herein are water-soluble films including a polyvinyl alcohol (PVOH) resin blend and optionally one or more additional components such as plasticizers, fillers, surfactants, and other additives. Also disclosed herein are articles including the water-soluble film and containing a composition such as a household care composition. The PVOH resin blend includes a PVOH copolymer including one or more types of anionic monomer units such as a PVOH terpolymer and a PVOH polymer such as a partially or completely hydrolyzed PVOH homopolymer. When the PVOH copolymer and PVOH polymer are blended in particular proportions and/or selected with regard to various criteria related to the 4% solution viscosity of one or both of the PVOH polymer(s) and PVOH copolymer(s), the resulting water-soluble film formed from the PVOH resin blend exhibits substantially improved aqueous dissolution properties.
Abstract:
The disclosure provides a water-soluble film, including polyvinyl alcohol (PVOH) and (PVOH) and an acrylate resin (e.g., methyl acrylate), wherein the water-soluble film remains intact for at least 3 minutes when submerged in water heated to a temperature of about 40° C., as determined by Bleach Compatibility Method A (described herein). The disclosure further provides a packet or pouch comprising water-soluble film of the disclosure. The packet or pouch can optionally include two or more compartments. The disclosure further provides a pouch including a first sealed compartment containing a first composition, the first sealed compartment comprising the water-soluble film according to the disclosure. Optionally, the first composition can include a bleach composition.
Abstract:
The present disclosure relates to pouches made from a combination of chemically different water-soluble films and optionally containing a composition (e.g. a household care composition or non-household care composition) that is at least partially enclosed by the water-soluble films in at least one compartment.
