Abstract
Water-soluble, single unit pouches containing a pre-measured amount of a solid bleaching agent, bleach activating agent, and stain-fighting enzymes that can be added to a volume of water to bleach and/or deodorize laundry or a surface are provided. Water-soluble, single unit pouches containing a pre-measured amount of a solid fabric softening agent and fragrance that can be added to a volume of water to soften a material are provided. Also provided are kits including the pouches, as well as methods for using such pouches for bleaching and/or softening a material or surface.
Claims21
A water-soluble pouch, comprising a body comprising polyvinyl alcohol and defining a container portion containing a stain-fighting composition comprising about 60% to about 76% by weight of a bleaching agent in solid form, about 20% to about 30% by weight of a bleach activating agent in solid form, about 1% to about 9% of an enzyme that catalyzes the breakdown of an oil-based stain in solid form, and about 0.5% to about 2.5% of an enzyme that catalyzes the breakdown of a protein-based stain or a starch-based stain in solid form, wherein the container portion has a single layer having an internal surface contacting the stain-fighting composition, and having an external surface which is the outermost portion of the pouch, and wherein the container portion does not contain any surfactant.
A water-soluble pouch, comprising a body comprising polyvinyl alcohol and defining a container portion containing a stain-fighting, fabric-softening composition comprising about 32% to about 36% by weight of a bleaching agent in solid form, about 11% to about 15% by weight of a bleach activating agent in solid form, about 2% to about 3% of an enzyme that catalyzes the breakdown of an oil-based stain in solid form, about 0.5% to about 0.9% of an enzyme that catalyzes the breakdown of a protein-based stain or a starch-based stain in solid form, about 47% to about 51% by weight of a fabric-softening in solid form, and about 0.5% to about 1.5% by weight of a fragrance absorbed into the fabric softening agent, wherein the container portion has a single layer having an internal surface contacting the stain-fighting, fabric-softening composition, and having an external surface which is the outermost portion of the pouch, wherein the container portion does not contain any surfactant, and wherein the fabric softening agent comprises particles from about 1 mm to about 3 mm in size, and the particles are optionally colored with a dye.
