## Abstract

A liquid oil dispersion cosmetic composition of the present invention is capable of implementing a refreshing and light feeling and has excellent dispersibility by containing surfactants, powders, and volatile substances having fast volatility, low viscosity and low density. In addition, the liquid oil dispersion cosmetic composition, according to the present invention, can prevent precipitation of the powders by being uniformly impregnated in between the pores of foam carriers, and thus, can maintain high formulation stability even during long-term storage.

## Claims

### Claim 1

An oil-dispersed liquid type cosmetic composition comprising:
a volatile material having a density of 0.6-0.9 g/mL;
a non-ionic silicone surfactant having a density of 0.9-1.1 g/mL and an HLB (hydrophile-lipophile balance) of 1-6;
powder; and
an organic UV protecting agent comprising at least one selected from a group consisting of octylmethoxy cinnamate, octylsalicylate, octocrylene, butylmethoxydibenzoylmethane, oxybenzone, octyltrizaone, menthylanthranilate, 3,4-methylbenzylidene camphor, isoamyl-p-methoxycinnamate, bisethylhexyloxyphenol methoxyphenyltriazine, and methylene bisbenzotriazolyltetramethylbutylphenol,
wherein the non-ionic silicone comprises PEG-10 Dimethicone.

### Claim 2 (depends on 1)

The oil-dispersed liquid type cosmetic composition according to claim 1, wherein the volatile material comprises at least one material selected from the group consisting of: at least one volatile silicone oil selected from cyclomethicone, trimethicone and dimethicone having a viscosity of 2.0 centistock (cs) or lower; at least one volatile hydrocarbon oil selected from isododecane and dodecane; and ethanol.

### Claim 3 (depends on 1)

The oil-dispersed liquid type cosmetic composition according to claim 1, wherein the powder comprises at least one selected from titanium dioxide, zinc oxide, silica and iron oxide.

### Claim 4 (depends on 1)

The oil-dispersed liquid type cosmetic composition according to claim 1, which comprises the volatile material in an amount of 10-70 wt % based on the total weight of the composition.

### Claim 5 (depends on 1)

The oil-dispersed liquid type cosmetic composition according to claim 1, which comprises the surfactant in an amount of 0.1-5 wt % based on the total weight of the composition.

### Claim 6 (depends on 1)

The oil-dispersed liquid type cosmetic composition according to claim 1, which comprises the powder in an amount of 0.1-50 wt % based on the total weight of the composition.

### Claim 7 (depends on 1)

### Claim 9 (depends on 1)

A cosmetic product comprising:
the oil-dispersed liquid type cosmetic composition as defined in claim 1; and
a foam carrier in which the oil-dispersed liquid type cosmetic composition is impregnated.

### Claim 10 (depends on 9)

The cosmetic product according to claim 9, wherein the foam carrier comprises polyurethane.

### Claim 11 (depends on 9)

The cosmetic product according to claim 9, wherein the foam carrier comprises pores having an average size of 30-2500 μm.

### Claim 12 (depends on 11)

The cosmetic product according to claim 11, wherein the oil-dispersed liquid type cosmetic composition is impregnated uniformly in the pores of the foam carrier and maintains a state distributed uniformly in the carrier.

### Claim 13 (depends on 1)

The oil-dispersed liquid type cosmetic composition according to claim 1,
wherein the powder comprises inorganic UV protecting agent comprising at least one selected from titanium dioxide having an average particle size of 5-100 nm, zinc oxide having an average particle size of 5-300 nm, or iron oxide having an average particle size of 5-300 nm.
