Abstract

The present invention relates to a cosmetic composition in which a W/O (water in oil) cosmetic composition with low viscosity is packaged in an airless container, and more specifically, to a cosmetic composition with low viscosity which enhances the stability of easily-separable low viscosity materials and improves user convenience by impregnating the W/O cosmetic composition with low viscosity into a urethane foam and packaging the composition in the airless container.

First claim

The invention claimed is:

1. A cosmetic composition application system comprising:
an airless single chamber container;
a urethane foam; and
a liquid cosmetic composition having a viscosity of 2,000-4,000 cps,
wherein the airless single chamber container is a pump dispenser;
wherein the urethane foam has a hardness of 10-70 and is packed inside the chamber of the container; and
wherein the liquid cosmetic composition is impregnated into the urethane foam.

2. The cosmetic composition application system of claim 1 , wherein the liquid cosmetic composition is a water-in-oil type cosmetic composition.

3. The cosmetic composition application system of claim 1 , wherein the liquid cosmetic composition contains, based on the total weight of the composition, 20 to 80 wt % of an oil-phase component, 0.01 to 10 wt % of an emulsifying agent, 1 to 35 wt % of a UV-blocking agent, 0.5 to 20 wt % of a pigment and 20 to 60 wt % of a water-phase component.

4. The cosmetic composition application system of claim 3 , wherein the oil-phase component is one or more selected from the group consisting of vegetable oils, synthetic ester oils, hydrocarbon oils and silicone oils.

5. The cosmetic composition application system of claim 3 , wherein the emulsifying agent is a nonionic surfactant having a hydrophilic lipophilic balance of 1 to 6.

6. The cosmetic composition application system of claim 3 , wherein the pigment is one or more selected from the group consisting of polymethylmethacrylate, silica, nylon, polyurethane, ultramarine, iron oxide, pearl, synthetic mica, mica, talc, sericite, and boron nitride.

7. The cosmetic composition application system of claim 3 , wherein the water-phase component is one or more selected from the group consisting of purified water, propylene glycol, 1,3-butylene glycol, and glycerin.

8. The cosmetic composition application system of claim 2 , wherein the liquid cosmetic composition is a composition for blocking UV rays.

9. The cosmetic composition application system of claim 2 , wherein the liquid cosmetic composition is selected from the group consisting of lotion, essence, sun milk lotion, liquid base, liquid foundation, and liquid BB cream.

10. The cosmetic composition application system of claim 1 , wherein the urethane foam has a hardness of 25, 30, 35, 40, 45, 50 or 55.

11. The cosmetic composition application system of claim 1 , wherein the liquid cosmetic composition has a viscosity of 2000, 3500, or 4000 cps.
