Abstract

To provide a transparent to translucent cosmetic composition which is highly stable, and can impart excellent actual feelings of effectiveness in use, such as a feeling of skin penetration, a feeling of non-stickiness, and a skin-softening effect after application thereof to the skin. A transparent to translucent cosmetic composition comprising: (a) a hydrogenated phospholipid, (b) one or more selected from among branched higher fatty acids and higher alcohols, and (c) a polyalcohol that acts as a good solvent and/or a poor solvent for component (a). Preferably, component (b) is isostearic acid and/or isostearyl alcohol. Preferably, the ratio of component (a)/component (b) is from 1/0.01 to 1/0.4 (by mass).

First claim

The invention claimed is:

1. A transparent to translucent cosmetic composition, which is any one selected from the group consisting of a lotion, impregnating liquid to be impregnated in a sheet-like base, and beauty essence, comprising:
(a) a hydrogenated phospholipid,
(b) one or more selected from among branched higher fatty acids and higher alcohols,
(c) a polyalcohol that acts as a good solvent and/or a poor solvent for component (a), and
(d) water,
wherein the ratio of component (a)/component (b) is from 1/0.01 to 1/0.4 (by mass), and
component (a) comprises 60% by mass or more of phosphatidylcholine.

2. The cosmetic composition as claimed in claim 1 , wherein component (b) is isostearic acid and/or isostearyl alcohol.

3. The cosmetic composition as claimed in claim 1 , wherein component (c) that acts as a good solvent for component (a) is one or more selected from among 1,3-butylene glycol, dipropylene glycol, and propylene glycol.

4. The cosmetic composition as claimed in claim 1 , wherein component (c) that acts as a poor solvent for component (a) is one or more selected from among glycerin, polyethylene glycol, polyoxyethylene methylglucoside, polyoxypropylene methylglucoside, sorbitol, and polyoxyethylene/polyoxypropylene dimethyl ether.

5. The cosmetic composition as claimed in claim 1 , having an L value of from 40 to 100.

6. The cosmetic composition as claimed in claim 2 , wherein component (c) that acts as a good solvent for component (a) is one or more selected from among 1,3-butylene glycol, dipropylene glycol, and propylene glycol.

7. The cosmetic composition as claimed in claim 2 , wherein component (c) that acts as a poor solvent for component (a) is one or more selected from among glycerin, polyethylene glycol, polyoxyethylene methylglucoside, polyoxypropylene methylglucoside, sorbitol, and polyoxyethylene/polyoxypropylene dimethyl ether.

8. The cosmetic composition as claimed in claim 2 , having an L value of from 40 to 100.

9. The cosmetic composition as claimed in claim 1 , wherein the cosmetic composition comprises more than 10% by mass of (d) water.

10. The cosmetic composition as claimed in claim 1 , wherein the cosmetic composition comprises the polyalcohol that acts as a good solvent for component (a) and the polyalcohol that acts as a poor solvent for component (a), and
the ratio of the polyalcohol that acts as a good solvent for component (a)/the polyalcohol that acts as a poor solvent for component (a) is from 4/1 to 1/2 (by mass).

11. The cosmetic composition as claimed in claim 1 , wherein the cosmetic composition comprises 0.001 to 3% by mass of component (a).

12. The cosmetic composition as claimed in claim 1 , wherein the cosmetic composition comprises 0.01 to 1% by mass of component (a).

13. The cosmetic composition as claimed in claim 1 , wherein the cosmetic composition comprises 0.01 to 0.5% by mass of component (a).

14. A method of reducing stickiness of a transparent to translucent cosmetic composition comprising (a) a hydrogenated phospholipid, (b) one or more selected from among branched higher fatty acids and higher alcohols, (c) a polyalcohol that acts as a good solvent and/or a poor solvent for component (a), and (d) water, the method comprising:
combining component (a) and component (b) in the cosmetic composition at a ratio of component (a)/component (b) of from 1/0.01 to 1/0.4 (by mass).
