## Abstract

Provided is a cosmetic composition which has a structure-recovering property, is transparent, is satisfactory in smoothness when applied to the skin or hair, and has a good feeling in use, which comprises components (A) to (D) as described.

## Claims

### Claim 1

A cosmetic composition comprising the following components (A) to (D), wherein the component (A) is from 0.1 to 30% by mass, the component (B) is from 0.1 to 50% by mass, the component (C) is from 50 to 95% by mass, and the component (D) is from 0.01 to 10% by mass, and a mass ratio of the component (A) to the component (B), (A)/(B) is from 1/5 to 5/1:
(A) a polyalkylene glycol derivative represented by the following formula (I):
Z—{O-(EO)a-(AO)k—H}m (I)
wherein Z is a residual group resulting from removal of hydroxyl groups from a polyhydric alcohol having 3 to 6 hydroxyl groups, m is from 3 to 6, EO is an oxyethylene group, AO is an oxyalkylene group having 4 to 8 carbon atoms, and EO and AO are bonded in a block form;
a represents an average addition mole number of EO and k represents an average addition mole number of AO, and a is from 1 to 50 and k is from 1 to 50; and a mass ratio of EO is from 10 to 75 parts by mass relative to 100 parts by mass of a total amount of EO and AO,
(B) a nonionic surfactant having a hydroxyl group and a hydrocarbon group having 12 to 22 carbon atoms and exhibiting an HLB of 3 to 8,
(C) one or two or more oily agents selected from ester oils and triglycerides which are liquid at 25° C., and
(D) water.

### Claim 2 (depends on 1)

The cosmetic composition according to claim 1, wherein a part of the component (C) is replaced by the following component (E) and an amount of the component (C) is 30 parts by mass or more relative to 100 parts by mass of a total amount of the component (C) and the component (E):
(E) one or two or more oily agents selected from hydrocarbon oils and silicone oils which are liquid at 25° C.

### Claim 3 (depends on 1)

The cosmetic composition according to claim 1, wherein AO is a 1,2-oxybutylene group.

### Claim 4 (depends on 1)

The cosmetic composition according to any one of claim 1, wherein the component (B) is a nonionic surfactant having a branched or unsaturated hydrocarbon group having 12 to 22 carbon atoms.

### Claim 5 (depends on 2)

The cosmetic composition according to claim 2, wherein AO is a 1,2-oxybutylene group.

### Claim 6 (depends on 2)

The cosmetic composition according to any one of claim 2, wherein the component (B) is a nonionic surfactant having a branched or unsaturated hydrocarbon group having 12 to 22 carbon atoms.

### Claim 7 (depends on 3)

The cosmetic composition according to any one of claim 3, wherein the component (B) is a nonionic surfactant having a branched or unsaturated hydrocarbon group having 12 to 22 carbon atoms.
