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

1 . A cosmetic composition, comprising:
(A) a first powder, comprising one or more N-medium-chain-acyl basic amino acids represented by formula (I):

wherein R is a saturated or unsaturated straight hydrocarbon group having 5 to 9 carbon atoms, and m is an integer of 1 to 4;
(B) a second powder which is an inorganic powder; and
(C) an oil material.

2 . The cosmetic composition according to claim 1 , wherein said component (A) exhibits an internal frictional angle of 10.0 to 17.0 degrees.

3 . The cosmetic composition according to claim 1 , wherein said component (A) comprises N ε -monooctanoyl lysine.

4 . The cosmetic composition according to claim 1 , wherein said component (A) is present in an amount of 0.1 to 95 wt % based on the entire weight of said cosmetic composition.

5 . The cosmetic composition according to claim 1 , wherein said component (B) is present in an amount of 4 to 99.5 wt % based on the entire weight of said cosmetic composition.

6 . The cosmetic composition according to claim 1 , wherein said component (C) is present in an amount of 0.01 to 95 wt % based on the entire weight of said cosmetic composition.

7 . The cosmetic composition according to claim 1 , wherein said component (A) and said component (B) are present in a weight ratio (weight of component (A):weight of component (B)) of 1:99 to 60:40.

8 . The cosmetic composition according to claim 1 , wherein said component (A) and said component (C) are present in a weight ratio (weight of component (A):weight of component (C)) of 0.5:99.5 to 90:10.

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

10 . The cosmetic composition according to claim 1 , wherein said component (A) consists essentially of one or more N-medium-chain-acyl basic amino acids represented by formula (I).

11 . The cosmetic composition according to claim 1 , wherein said component (A) consists of one or more N-medium-chain-acyl basic amino acids represented by formula (I).

12 . The cosmetic composition according to claim 1 , wherein said component (B) comprises talc.

13 . 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.

14 . 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.
