Abstract

Provided is a cleansing composition of acyl amino acid, showing good foamability and good lather retention effect, which is rinsed off quickly and affords superior skin texture after drying. A cleansing composition containing the following components (A), (B) and (C), wherein a weight ratio of (A)/(B) is 0.2-5 and a weight ratio of ((A)+(B))/(C) is 2.5-10.0:
(A) N-lauroylglycine or a salt thereof (B) N-myristoylglycine or a salt thereof (C) N-acyl acidic amino acid having an acyl group having 8-24 carbon atoms, or a salt thereof.

First claim

The invention claimed is:

1. A cleansing composition, comprising:
(A) N-lauroylglycine or at least one salt thereof;
(B) N-myristoylglycine or at least one salt thereof; and
(C) at least one N-acyl acidic amino acid selected from the group consisting of lauroyl glutamic acid and cocoyl glutamic acid, or a salt thereof,
wherein a weight ratio of (A)/(B) is 0.3 to 3.5 and a weight ratio of ((A)+(B))/(C) is 4 to 9,
wherein said composition is a liquid.

2. The cleansing composition according to claim 1 , wherein said (C) is lauroyl glutamic acid or a salt thereof.

3. The cleansing composition according to claim 1 , wherein said (C) at least one N-acyl acidic amino acid salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

4. The cleansing composition according to claim 2 , wherein said (C) at least one N-acyl acidic amino acid salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

5. The cleansing composition according to claim 1 , wherein said (C) is at least one member selected from the group consisting of N-lauroylglutamic acid, a sodium salt of N-lauroylglutamic acid, a potassium salt of N-lauroylglutamic acid, a triethanolamine salt of N-lauroylglutamic acid, N-cocoylglutamic acid, a sodium salt of N-cocoylglutamic acid, a potassium salt of N-cocoylglutamic acid, and a triethanolamine salt of N-cocoylglutamic acid.

6. The cleansing composition according to claim 1 , wherein said (A) N-lauroylglycine salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

7. The cleansing composition according to claim 2 , wherein said (A) N-lauroylglycine salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

8. The cleansing composition according to claim 3 , wherein said (A) N-lauroylglycine salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

9. The cleansing composition according to claim 4 , wherein said (A) N-lauroylglycine salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

10. The cleansing composition according to claim 5 , wherein said (A) N-lauroylglycine salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

11. The cleansing composition according to claim 1 , wherein said (B) N-myristoylglycine salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

12. The cleansing composition according to claim 2 , wherein said (B) N-myristoylglycine salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

13. The cleansing composition according to claim 3 , wherein said (B) N-myristoylglycine salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

14. The cleansing composition according to claim 4 , wherein said (B) N-myristoylglycine salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

15. The cleansing composition according to claim 5 , wherein said (B) N-myristoylglycine salt is a salt with at least one member selected from the group consisting of sodium, potassium, and triethanolamine.

16. The cleansing composition according to claim 1 , which has a pH 6 to 10.

17. The cleansing composition according to claim 2 , which has a pH 6 to 10.

18. The cleansing composition according to claim 1 , wherein said (C) is cocoyl glutamic acid or a salt thereof.
