Abstract

The present invention provides an eye make-up cosmetic composition containing a low-specific-gravity oil and a low-specific-gravity powder. The present invention provides an eye make-up cosmetic composition with excellent curling holding force, wherein the composition does not contain water and aqueous ingredients at all and contains a low-specific-gravity oil and a low-specific-gravity powder together, thereby allowing a formed curling force to be maintained as is, all day, when the composition is coated on hair such as the eyelashes.

First claim

The invention claimed is:

1. A cosmetic composition for eye makeup, which comprises low-specific gravity volatile oil and low-specific gravity powder, and a dispersant,
wherein the low-specific gravity volatile oil comprises low-specific gravity hydrocarbon oil and low-specific gravity volatile silicone oil,
wherein a specific gravity of the low-specific gravity hydrocarbon oil is equal to or more than 0.1 and equal to or less than 0.8, and a specific gravity of the low-specific gravity silicone oil is equal to or more than 0.1 and equal to or less than 0.85, and the specific gravity of the low-specific gravity powder is equal to or more than 0.001 and less than 1, when the specific gravity of the standard material, pure water at 4° C., is taken as 1, wherein the composition is a non-aqueous composition not comprising water or aqueous ingredients.

2. The cosmetic composition for eye makeup according to claim 1 , wherein the low-specific gravity volatile hydrocarbon oil is a C8-C16 branched alkane, ester or a mixture thereof.

3. The cosmetic composition for eye makeup according to claim 1 , wherein the low-specific gravity volatile silicone oil is dimethicone, trisiloxane, or a mixture thereof.

4. The cosmetic composition for eye makeup according to claim 1 , which comprises the low-specific gravity volatile oil in an amount of 1-80 wt % based on the total weight of the composition.

5. The cosmetic composition for eye makeup according to claim 1 , wherein the low-specific gravity powder comprises at least one selected from the group consisting of talc, sericite, mica, calcium carbonate, magnesium carbonate, kaolin, boron nitride, titanium dioxide, zinc oxide, iron oxide, carbon black, cerium oxide, zirconium oxide, silica, nylon and polymethyl methacrylate.

6. The cosmetic composition for eye makeup according to claim 1 , wherein the low-specific gravity powder has at least one shape selected from a spherical shape, plate-like shape and a needle-like shape, and has an average particle diameter of 0.1-20 μm.

7. The cosmetic composition for eye makeup according to claim 1 , which comprises the low-specific gravity powder in an amount of 0.1-20 wt % based on the total weight of the composition.

8. The cosmetic composition for eye makeup according to claim 1 , which has a specific gravity equal to or more than 0.001 and less than 1 as a whole.

9. The cosmetic composition for eye makeup according to claim 1 , wherein the dispersant comprises at least one selected from the group consisting of polyhydroxystearic acid, lecithin, ethylhexylpalmitate, isopropylpalmitate, isostearic acid and polyglyceryl-3 polyricinoleate.

10. The cosmetic composition for eye makeup according to claim 1 , which comprises the dispersant in an amount of 1-50 wt % based on the total weight of the low-specific gravity powder.

11. The cosmetic composition for eye makeup according to claim 1 , which is for use in mascara.
