## Abstract

The present invention provides an oil-in-water emulsion composition thickened with a hydrophobically modified polyether urethane, the composition having improved high-temperature stability and giving a pudding-like unique feeling. The invention provides an elastic jelly-like composition characterized in that a hydrophobically modified polyether urethane has been incorporated into an oil-in-water emulsion including oil droplets with an average particle diameter of 150 nm or smaller. The elastic jelly-like composition is transparent or translucent, gives a pudding-like elastic feeling, has excellent viscosity stability at high temperatures, and is suitable for use as a cosmetic-preparation base. The hydrophobically modified polyether urethane is especially preferably a PEG-240/decyltetradeceth-20/HDI copolymer.

## Claims

### Claim 1

An oil-in-water emulsified elastic composition having a jiggling texture, the composition comprising:
an oil phase in the form of droplets having an average particle size of 150 nm or less; and
a water phase comprising 0.4 to 10% by mass, relative to the total amount of the composition, of a hydrophobically modified ethoxylated urethane;
wherein the oil droplets comprise an α-gel consisting of a higher alcohol having a carbon chain length of 16 or more, an oil component, and a surfactant selected from cationic and anionic surfactants.

### Claim 2 (depends on 1)

The composition according to claim 1, wherein: the hydrophobically modified ethoxylated urethane is represented by the following formula (I):
R1—{(O—R2)k—OCONH—R3[—NHCOO—(R4—O)n—R5]h}m (I)
wherein R1, R2, and R4 each independently represent a hydrocarbon group having 2 to 4 carbon atoms; R3 represents a hydrocarbon group having 1 to 10 carbon atoms; R5 represents a hydrocarbon group having 8 to 36 carbon atoms; m is a number of 2 or more; h is a number of 1 or more; k is a number of 1 to 500; and n is a number of 1 to 200.

### Claim 3 (depends on 2)

The composition according to claim 2, wherein: the hydrophobically modified ethoxylated urethane is the urethane having INCI name PEG-240/HDI copolymer bis-decyltetradeceth-20 ether.

### Claim 4 (depends on 1)

A cosmetic base comprising: the composition according to claim 1.
