## Abstract

The present invention relates to a cosmetic product comprising a UV-blocking W/O or O/W composition of low viscosity packaged in a compact-type container. More specifically, the invention relates to a UV-blocking cosmetic product prepared by impregnating a UV-blocking W/O or O/W cosmetic composition of low viscosity into expanded urethane foam, preparing a compact formulation from the expanded urethane foam impregnated with the composition, and then packaging the compact formulation in a cosmetic container. Thus, the UV-blocking cosmetic product is convenient for the user to carry and use and also has a skin-cooling effect.

## Claims

### Claim 1

A cosmetic container containing an expanded urethane foam impregnated with a cosmetic composition, and an applicator,
wherein the expanded urethane foam has a hardness of 35-55 as measured after impregnation with a durometer hardness tester type F, manufactured by ASKER, and the cosmetic composition is a UV-blocking cosmetic composition having a viscosity of 5000-15000 cps and containing, in percent by weight based on the total weight of the composition,
20-80 wt % of an oil-phase component forming the outer phase of the composition,
0.01-10 wt % of an emulsifying agent having an HLB from 1 to 17,
1-35 wt % of a UV-blocking agent,
0.1-20 wt % of a pigment,
30-70 wt % of a water phased component.

### Claim 2 (depends on 1)

The cosmetic container of claim 1, wherein the UV-blocking cosmetic composition is a water-in-oil (W/O) or oil-in-water (O/W) type.

### Claim 3 (depends on 1)

The cosmetic container of claim 1, wherein the UV-blocking agent(s) comprise(s) at least one inorganic or organic UV-blocking agent(s).

### Claim 4 (depends on 3)

The cosmetic container of claim 3, wherein the inorganic UV-blocking agent(s) is/are at least one selected from a group consisting of titanium dioxide, zinc oxide and iron oxide.

### Claim 5 (depends on 3)

The cosmetic container of claim 3, wherein the organic UV-blocking agent(s) is/are at least one selected from a group consisting of octyl methoxycinnamate, octyl salicylate, octocrylene, butyl methoxydibenzoylmethane, oxybenzone, octyltriazone, menthyl anthranilate, 3,4-methylbenzylidene camphor, isoamyl-P-methoxycinnamate, bis-ethylhexylphenol methoxyphenyl triazine and methylene bis-benzotrizolyl tetramethylbutylphenol.

### Claim 6 (depends on 1)
