Abstract

PROBLEM TO BE SOLVED: To obtain a makeup cosmetic, excellent in makeup lasting quality and readily removable with a usual cleansing agent. SOLUTION: This stratified makeup cosmetic is obtained by using a makeup ground agent for the first layer containing one or more fatty acids selected from free fatty acids which are liquid at normal temperature, especially oleic acid and isostearic acid and a makeup cosmetic for the second layer containing one or more powders selected from magnesium oxide, calcium oxide and zinc oxide in combination. The resultant makeup cosmetic has characteristics of forming a strong film of a metallic soap on the skin, excellent in improving effects on makeup lasting, especially improving effects on the persistence of a cosmetic film. The surface of another powder is further coated with the one or more powders selected from the magnesium oxide, calcium oxide and zinc oxide and the coated powder is then blended with the makeup cosmetic for the second layer to thereby provide effective improving effects on the makeup lasting, especially improving effects on the persistence of the cosmetic film by a smaller amount of the blended powder.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a makeup base material for a first layer and a makeup cosmetic material for a second layer, which are used in combination to make up the makeup, and particularly, the durability of the makeup coating film is very good. , A multilayer makeup cosmetic that can be easily removed by a normal cleansing operation.

[0002]

2. Description of the Related Art Generally, it is essential for makeup cosmetics to have long-lasting makeup, and many studies have been conducted to improve long-lasting makeup.

For example, a make-up cosmetic composition has been proposed in which the powder is treated with reactive silicone and the treated powder is blended (Japanese Patent Publication No. 56-43264). This treated powder has a small color change over time and is excellent in preventing dullness over time, but it was not so effective in removing the makeup coating film by touching with a finger.

Further, in order to improve the durability of the makeup, particularly the durability of the makeup coating film, it is generally practiced to incorporate metal soap or powder whose surface is coated with metal soap. However, although the cosmetic longevity improving effect is recognized by adding the metal soap, when a large amount of the metal soap is added in the formulation, the bulk hardness increases and the usability is deteriorated.

Further, it has been disclosed that when a makeup cosmetic containing zinc oxide comes into contact with sebum, the free fatty acid in the sebum and zinc oxide form a metallic soap, which becomes a gel or a solid to improve the cosmetic durability. (Japanese Patent Laid-Open No. 61-25
7909). However, the present situation is that the amount of sebum present on the human face is very small, and the amount of sebum varies widely depending on the site, so that a large effect of improving makeup retention is not obtained.

[0006] Further, a film of high polymerization silicone is formed on the skin by using high polymerization silicone in combination with a volatile oil agent for the purpose of improving the durability of makeup. However, it is necessary to use a dedicated cleansing agent because the film of high-polymerization degree silicone is hard to be removed by an ordinary cleansing agent.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to obtain a make-up cosmetic composition which has a very long-lasting makeup, particularly the durability of the makeup coating film, and which can be easily removed by a normal cleansing operation.

[0008]

In order to achieve the above object, as a result of research, a makeup base material for the first layer containing free fatty acid which is liquid at room temperature, magnesium oxide, calcium oxide, zinc oxide. By using a combination of makeup cosmetics for the second layer containing one or more powders selected from the following, a strong metal soap film is formed on the skin, and the makeup lasts, especially for the makeup coating film. The present invention has been completed by finding out that it has an excellent effect of improving sustainability and has the property of being easily removed by a normal cleansing agent.

First, the make-up base material for the first layer of the present invention is used directly or after applying a basic cosmetic such as a lotion or emulsion, or a sunscreen agent.
The free fatty acid which is liquid at room temperature and used in the first layer makeup base material is not particularly limited, but one or two kinds selected from oleic acid and isostearic acid, which are one of sebum components, are preferred examples. To be The blending amount of oleic acid and isostearic acid is not particularly limited, but is preferably 2% by weight or more, and more preferably 5% by weight or more in order to obtain a stronger cosmetic lasting action. The branching position and branch chain length of isostearic acid used here are not particularly limited, and one type can be used alone or isostearic acid having a different branching chain can be used in combination.

Next, the makeup cosmetic for the second layer used in the present invention is used after applying the makeup base material for the first layer. This makeup cosmetic for the second layer contains one or more powders selected from magnesium oxide, calcium oxide and zinc oxide. The particle size and particle shape of these powders are not particularly limited.

Further, one or more powders selected from magnesium oxide, calcium oxide and zinc oxide are added,
Silicic acid anhydride, talc, mica, sericite, kaolin,
By using an inorganic powder such as titanium dioxide or an organic powder such as polyacrylic resin, nylon, or polyethylene as a core substance for surface coating, the surface area becomes large and the reactivity with fatty acids increases, so that the makeup lasts especially for makeup. The durability of the coating film is improved.

The amount of one or more powders selected from magnesium oxide, calcium oxide and zinc oxide in the makeup cosmetics for the second layer is not particularly limited. It is desirable to blend the free fatty acid blended with the powder in an equimolar concentration or in an excess amount.
