Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a three-layer cosmetic composition, more specifically, a specific amount of phospholipid, a water-soluble polymer,
By containing water and powder, it has a beautiful appearance that it is separated into three layers when standing, has excellent redispersibility that is easily uniform by shaking (shaking) during use, and has a good feeling in use. It relates to a three-layer cosmetic.

[0002]

2. Description of the Related Art Conventionally, multilayer cosmetics include a two-layer type consisting of a liquid layer / liquid layer, a liquid layer / powder layer, and a three-layer type consisting of a liquid layer / liquid layer / powder layer. When used, it is used by shaking lightly to make the system uniform. Since these cosmetics are often a mixed system of components that are incompatible with each other or have low compatibility with each other, they are characterized in that there are relatively few restrictions on the components to be mixed, as compared with emulsified cosmetics and the like.

Among these, a liquid layer / powder layer type, that is, a two-layer type cosmetic composition in which powder is mixed in a liquid layer composed of an aqueous component, an upper layer is a liquid layer and a lower layer is a powder layer is the most preferable. It is common. This type of two-layer cosmetic is fresh when used and gives a dry feel after use, so a sunscreen with a UV blocking agent such as particulate titanium oxide in the water-based liquid layer and an astringent effect. It is used as a cosmetic called calamine lotion, which is a mixture of the powders. On the other hand, as a cosmetic having three or more layers, a multi-layered cosmetic in which polyethylene glycol having a specific molecular weight and powder in a specific shape are blended to form a liquid layer (oil layer) / liquid layer (water layer) / powder layer Fees have also been proposed (Japanese Patent Laid-Open No. 10-1823).
No. 40).

[0004]

However, the development of a three-layer type cosmetic composition which has the above-described excellent usability and which has a novel appearance, which is composed of a white turbid layer and a transparent layer, has never been developed. The reality was that it was rarely practiced until that time.

[0005]

In view of the above situation, the present inventors have conducted diligent research to solve the above problems, and as a result,
By containing a specific amount of phospholipid, water-soluble polymer, water and powder, it separates into three layers of white turbid layer, transparent layer and white turbid layer when standing, and further moist feeling during use, after use The inventors have found that a three-layer cosmetic having a refreshing feeling and good redispersibility after standing for a long period of time can be obtained, and completed the present invention.

That is, the present invention provides the following components (a)-
(D); (a) Phospholipid 0.01 to 10% by mass (b) Water-soluble polymer 0.001 to 5% by mass (c) Water (d) Powder 0.1 to 5% by mass, A three-layer cosmetic, wherein the upper layer is a cloudy layer, the intermediate layer is a transparent layer, and the lower layer is a cloudy layer. Furthermore, the three-layer type cosmetic composition is characterized in that the average particle diameter of the component (d) is 0.1 to 10.0 μm. Moreover,
In addition to the above essential components, a three-layer type cosmetic composition is characterized by further containing 0.001 to 30 mass% of an oil agent as component (e). The details will be described below.
