Description

  The present invention relates to a cosmetic excellent in use feeling at the time of application, moisturizing feeling, skin feeling of the next day, and stability over time.

  Conventionally, cosmetics containing various types of oils have been developed in order to impart an excellent moisturizing feeling to cosmetics.

  However, with conventional cosmetics, by increasing the amount of oil, a moist and rich feeling immediately after application can be obtained, but the elongation at the time of application is also poor, and the skin feeling (brightness / softness) of the next day is good. Was not obtained.

  Recently, attempts have been made to prepare cosmetics using phospholipids, which are natural ingredients. For example, a cream using a combination of lecithin, a higher alcohol that is liquid at room temperature and glycerin has been introduced as an emulsified cosmetic with high safety, excellent affinity for skin, and excellent moisture retention (see, for example, Patent Document 1). ).

  On the other hand, oils and fats extracted from plant seeds have been conventionally used in foods (see, for example, Patent Document 2 or 3).

Japanese Patent No. 2944258 JP-A-3-236744 JP 2001-299278 A

  The present invention has been made to solve such conventional problems, and an object of the present invention is to provide a cosmetic excellent in use feeling, moisturizing feeling, next day's skin feeling and stability over time. It is what.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor has found that the combination of lecithin and solid oil extracted from plant seeds in the cosmetics has a synergistic effect, and has an unprecedented feeling of use, moisturizing feeling, and the next day's skin. The present inventors have found that a cosmetic material excellent in actual feeling and stability over time can be obtained, and completed the present invention.

  That is, the present invention is a cosmetic comprising lecithin as component (a) and solid fat extracted from plant seeds as component (b).

  The component (a) is selected from the group consisting of soybean lecithin, egg yolk lecithin, and hydrogenated products thereof, and a group consisting of phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phosphatidylglycerol, phosphatidylinositol, and sphingophospholipid.
