## Abstract

Described are personal care compositions, comprising an aqueous dispersion comprising an ethylene acrylic acid copolymer and a least one cosmetically acceptable surfactant, emollient, or cosmetic active.

## Claims

### Claim 1

A personal care composition, comprising:
an aqueous dispersion comprising an ethylene acrylic acid copolymer, said aqueous dispersion being present in the personal care composition in an amount from about 0.25 wt % to about 5 wt % by weight of the composition; and
about 7 wt % to about 18 wt %, by weight of the composition, of a detergent surfactant,
wherein the personal care composition is a shampoo, a rinse-off conditioner, a leave-in conditioner, or a body wash; and
wherein the ethylene acrylic acid copolymer is present in a range from about 10 wt % to about 30 wt % by weight of the aqueous dispersion.

### Claim 2 (depends on 1)

The personal care composition of claim 1, provided that the personal care composition is not an emulsion.

### Claim 3 (depends on 1)

The personal care composition of claim 1, wherein the aqueous dispersion comprises at least one anti-dandruff active, sunscreen active, pigment, fragrance, botanical, amino acid, or vitamin.

### Claim 4

A personal care composition, comprising:
an aqueous dispersion comprising an ethylene acrylic acid copolymer and a metallocene catalyzed polyolefin, said aqueous dispersion being about 30 wt % to about 50 wt % solids; and
at least one cosmetically acceptable surfactant, emollient, or cosmetic active,
wherein the personal care composition is a shampoo, a rinse-off conditioner,
a leave-in conditioner, or a body wash; and
wherein the ethylene acrylic acid copolymer is present in a range from about 1 wt % to about 25 wt % by weight of the aqueous dispersion.

### Claim 5 (depends on 4)

The personal care composition of claim 4, wherein the metallocene catalyzed polyolefin comprises at least one of ethylene/octene copolymers, ethylene/butene copolymers, ethylene/hexene copolymers, ethylene/propylene or ethylene/butene/hexene terpolymers.

### Claim 6 (depends on 4)

The personal care composition of claim 4, wherein the ethylene acrylic acid copolymer and metallocene catalyzed polyolefin is in a polymer ratio of about 40:60 to about 15:85.

### Claim 7 (depends on 1)

The personal care composition of claim 1, wherein the aqueous dispersion is present in a range from about 0.05 wt % to about 10 wt %.

### Claim 8 (depends on 1)

The personal care composition of claim 1, further comprising a silicone, provided that the silicone is not in the aqueous dispersion.

### Claim 9 (depends on 4)

The personal care composition of claim 4, wherein the surfactant is present and is a detergent surfactant.

### Claim 10 (depends on 4)

The personal care composition of claim 4, wherein the surfactant is present and is a nonionic surfactant.
