## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The pouch of claim 1, wherein the stain-fighting composition comprises about 65% to about 70% of a bleaching agent in solid form, about 24% to about 26% of a bleach activating agent in solid form, about 4% to about 6% of an enzyme that catalyzes the breakdown of an oil-based stain in solid form, and about 1% to about 1.5% of an enzyme that catalyzes the breakdown of a protein-based stain or a starch-based stain in solid form.

### Claim 3 (depends on 1)

The pouch of claim 1, wherein the stain-fighting composition comprises about 68% of a bleaching agent in solid form, about 26% of a bleach activating agent in solid form, about 5% of an enzyme that catalyzes the breakdown of an oil-based stain in solid form, and about 1% of an enzyme that catalyzes the breakdown of a protein-based stain or a starch-based stain in solid form.

### Claim 4 (depends on 1)

The pouch of claim 1, wherein the stain-fighting composition comprises about 68.1% of a bleaching agent in solid form, about 25.5% of a bleach activating agent in solid form, about 5.1% of an enzyme that catalyzes the breakdown of an oil-based stain in solid form, and about 1.3% of an enzyme the catalyzes the breakdown of a protein-based stain or a starch-based stain in solid form.

### Claim 5 (depends on 1)

The pouch of claim 1, wherein the bleaching agent is sodium percarbonate.

### Claim 6 (depends on 1)

The pouch of claim 1, wherein the bleach activating agent is tetra-acetylethylenediamine.

### Claim 7 (depends on 1)

The pouch of claim 1, wherein the enzyme that catalyzes the breakdown of an oil-based stain comprises a lipase.

### Claim 8 (depends on 1)

The pouch of claim 1, wherein the enzyme that catalyzes the breakdown of a protein-based stain or a starch-based stain comprises a protease, an amylase, a cellulase, or a combination thereof.

### Claim 9 (depends on 1)

The pouch of claim 1, wherein the stain-fighting composition is contained in the pouch in an amount sufficient for one regular laundry cycle.

### Claim 10 (depends on 1)

The pouch of claim 1, wherein the stain-fighting composition is contained in the pouch in an amount sufficient for one high efficiency laundry cycle.

### Claim 11 (depends on 1)

A kit, comprising the pouch of claim 1 and instructions for using the pouch in a method for removing stains in laundry or on a surface.

### Claim 12 (depends on 11)

The kit of claim 11, further comprising a second water-soluble pouch comprising a body comprising polyvinyl alcohol and defining a container portion containing a fabric-softening composition comprising about 94% to about 99% by weight of a fabric-softening agent in solid form, and about 1% to about 6% 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 fabric-softening composition, and having an external surface which is the outermost portion of the second pouch, and wherein the container portion does not contain any surfactant.

### Claim 13 (depends on 1)

A method for removing stains and odors from laundry, comprising adding the pouch of claim 1 to a volume of water such that the pouch dissolves in the water thereby creating a water solution comprising a stain-fighting composition, contacting laundry in need of stain-removal with the water solution for a period of time sufficient to remove stains from the laundry, and after the period of time has elapsed, rinsing the laundry to remove the water solution from the laundry.

### Claim 14

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.

### Claim 15 (depends on 14)

### Claim 17 (depends on 14)

The pouch of claim 14, wherein the stain-fighting, fabric softening composition is contained in the pouch in an amount sufficient for one regular laundry cycle.

### Claim 18 (depends on 14)
