## Abstract

Provided are personal care compositions including (a) hydrophobic ester oil, (b) at least one of a nonionic or anionic surfactant, and (c) one or more polymers containing polymerized structural units of (i) 79 to 95.74 weight % of C4-C8 (meth)acrylate monomers, (ii) 0.5 to 5 weight % of (meth)acrylic acid monomer, (iii) 3.75 to 14 weight % of (methoxy) poly(ethylene glycol) methacrylates, and (iv) 0.01 to 2 weight % of at least one crosslinker.

## Claims

### Claim 1

A personal care composition comprising:
(a) at least one cosmetically acceptable hydrophobic ester oil, wherein the cosmetically acceptable hydrophobic ester oil comprises one or more aliphatic C8-C24 alkyl triglycerides;
(b) at least one surfactant selected from the group consisting of nonionic surfactants, anionic surfactants, and mixtures thereof; and
(c) one or more polymers comprising polymerized structural units of
(i) 84.5 to 91.45 weight % of C4-C8 (meth)acrylate monomers, wherein the C4-C8 (meth)acrylate monomers comprise i-butyl methacrylate and ethyhexyl methacrylate in a ratio of from 3:2 to 2:3,
(ii) 0.5 to 5 weight % of (meth)acrylic acid monomer,
(iii) 3.75 to 14 weight % of (methoxy) poly(ethylene glycol) methacrylates, and
(iv) 0.01 to 2 weight % of at least one crosslinker.

### Claim 2 (depends on 1)

The personal care composition of claim 1, wherein the at least one surfactant comprises a nonionic surfactant and an anionic alkyl ether sulfate surfactant, wherein the nonionic surfactant has a hydrophile-lipophile balance value of from 7 to 14.

### Claim 3 (depends on 2)

The personal care composition of claim 2, wherein the nonionic surfactant has a hydrophile-lipophile balance value of from 9 to 12.

### Claim 4 (depends on 2)

The personal care composition of claim 2, wherein the anionic alkyl ether sulfate surfactant comprises at least one of a triethanolamine salt and a monoisopropanolamine salt.

### Claim 5 (depends on 1)

The personal care composition of claim 1, wherein the (methoxy) poly(ethylene glycol) methacrylates have a weight average molecular weight of from 200 to 2300.

### Claim 6 (depends on 1)

The personal care composition of claim 1, wherein the (methoxy) poly(ethylene glycol) methacrylates have a weight average molecular weight of from 300 to 600.

### Claim 7 (depends on 1)

The personal care composition of claim 1, wherein the crosslinker is selected from the group consisting of trimethylolpropane trimethacrylate, trimethylolpropane diallyl ether, ethylene glycol dimethylacrylate, polypropylene glycol dmiethacrylate, and combinations thereof.
