## Abstract

Cosmetic compositions having durable gloss, such as cosmetic lipcolors, are provided. The compositions comprise a gel formed from a cellulosic polymer and a polar oil, a non-polar film-forming agent, polyhydroxystearic acid, and optionally one or more pigments. The compositions may have one or more properties selected from long-wear, oil transfer resistance, water transfer resistance, comfort, and durable shine.

## Claims

### Claim 1

A method for providing a long-wearing durable film on the lips comprising applying to the lips a composition comprising:
(1) a polar oil comprising a fatty alcohol;
(2) a cellulose ether capable of forming a gel with said polar oil;
(3) a non-polar film-forming polyolefin polymer;
(4) polyhydroxystearic acid; and
(5) pigments;
to form a durable film on the lips characterized by high gloss and transfer-resistance, wherein (1)-(5) were mixed under shear; and
wherein said composition is characterized by greater color development than an otherwise identical composition in which (4) was added after (1)-(3) and (5) were mixed under shear; and
wherein the composition comprises less than 1% by weight wax.

### Claim 2 (depends on 1)

The method according to claim 1, wherein said polar oil further comprises an ester oil.

### Claim 3 (depends on 1)

The method according to claim 1, wherein said polar oil comprises octyldodecanol.

### Claim 4 (depends on 1)

The method according to claim 1, wherein said cellulose ether is ethyl cellulose.

### Claim 5 (depends on 1)

The method according to claim 1, wherein said polyolefin is polybutene.

### Claim 6 (depends on 1)

The method according to claim 1, wherein said cellulose ether comprises from about 1% to about 2.5% by weight and said polar oil comprises from about 5% to about 35% by weight of said composition.

### Claim 7 (depends on 1)

The method according to claim 1, wherein said composition is substantially free of water.
