Abstract

The present invention provides a cosmetic composition containing (A) a powder composed of one or more kinds of the N-medium-chain-acyl basic amino acid powder represented by the following formula (I), (B) an inorganic powder, and (C) an oil material:

wherein R is a saturated or unsaturated straight hydrocarbon group having 5-9 carbon atoms, and m is an integer of 1-4.

First claim

The invention claimed is:

1. A cosmetic composition, comprising:
(A) an N-acyl basic amino acid powder;
(B) an inorganic powder; and
(C) an oil material comprising silicone oil,
wherein:
said N-acyl basic amino acid powder consists of one or more N-medium-chain-acyl basic amino acids selected from the group consisting of N ε -monohexanoyl lysine, N ε -monooctanoyl lysine and N ε -monodecanoyl lysine,
said N-acyl basic amino acid powder is present in an amount of 2.0 to 32.4 wt % based on the entire weight of said cosmetic composition,
said inorganic powder is present in an amount of 50.6 to 87.0 wt % based on the entire weight of said cosmetic composition,
said oil material is present in an amount of 1.0 to 47.4 wt % based on the entire weight of said cosmetic composition,
said N-acyl basic amino acid powder and said inorganic powder are present in a weight ratio (weight of said N-acyl basic amino acid powder:weight of said inorganic powder) of: 2.2:97.8 to 36.4:63.6, and
said N-acyl basic amino acid powder and said oil material are present in a weight ratio (weight of said N-acyl basic amino acid powder:weight of said oil material) of 15.4:84.6 to 74.7:25.3.

2. The cosmetic composition according to claim 1 , wherein said N-acyl basic amino acid powder exhibits an internal frictional angle of 10.0 to 17.0 degrees.

3. The cosmetic composition according to claim 1 , wherein said N-acyl basic amino acid powder consists of N e -monooctanoyl lysine.

4. The cosmetic composition according to claim 1 , which is a solid cosmetic.

5. The cosmetic composition according to claim 1 , wherein said inorganic powder comprises talc.

6. A method of controlling the color of the skin or lips and/or adding color to the skin or lips, comprising applying a cosmetic composition according to claim 1 to the skin or lips of a subject in need thereof.

7. A method of UV shielding of skin, comprising applying a cosmetic composition according to claim 1 to the skin of a subject in need thereof.
