Abstract: A polymeric film material for the rinse release of wash additives comprises a blend of polyvinyl alcohol and an alkyl cellulose. A metalloid oxide cross-linking agent is present in an amount sufficient to sharply reduce the solubility rate of the film blend in an alkaline wash, yet allow dissolution in a less alkaline rinse. Optionally, a hydrophobic cationic species is included to further reduce the dissolution rate in the wash pH. The films remain intact during normal wash cycles and over a range of typical water temperatures, then rapidly dissolve in the rinse. The film can be used to microencapsulate an additive, or made into a water-soluble pouch, or as a soluble seal for a pouch or container.

Abstract: A thickened cleaning composition for laundry products incorporates low levels of a fluorescent whitening agent or dye, a surfactant, an acidic pH adjusting agent and an insoluble peracid precursor. At the acidic pH, the fluorescent whitening agent precipitates as a colloidal particle, and is stabilized by associating with the surfactant, resulting in thickening. The precursor is stably suspended in its inactive form in the thickener, and provides oxidizing power as the corresponding peracid is formed when added to an alkaline wash or rinse solution. The composition preferably is formulated with an acidic soluble bleach source and most preferably with a peroxygen bleach.

Abstract: This invention relates to a storage and shipping system comprising corrugated containers which house plastic vessels or bottles used to hold fragranced liquid bleaches in which the shipping and storage containers are stacked on top of one another. In the stacks in all of the shipping and storage containers except for the topmost one, the plastic vessels will share some of the vertical component of the compression load caused by the shipping and storage container directly located above a given shipping and storage container. The compression load can cause stress-cracking in the vessels or bottles if strongly wetting surfactants are used to disperse the fragrances.
