Description

  The present invention relates to a three-layer cosmetic. According to the present invention, a three-layer cosmetic having a stable three-layer structure can be obtained.

The multi-layer cosmetic is used by mixing cosmetics separated into two or more layers at the time of standing by shaking at the time of use. Because of the appearance feature of separation into a plurality of layers upon standing, it is widely used as a cosmetic having an appearance beauty. On the other hand, since the layers are separated at the time of standing, the cosmetic component (for example, the active ingredient) contained in each layer is stably stored.
For example, a three-layer cosmetic composition containing 10 to 50% by weight of dimethylpolysiloxane, 20 to 50% by weight of a liquid oil, and 20 to 50% by weight of an aqueous alcohol solution (patent) Literature 1) has been proposed, but this three-layer type cosmetic composition was irritated to the skin and eyes by alcohol.

Japanese Patent Publication No. 1-45444 JP-A-7-165553 JP-A-11-71230

Patent Document 2 discloses a liquid three-layer composition comprising an upper layer composed of a liquid oily component, an intermediate layer composed of a specific nonionic surfactant, and a lower layer composed of a hydrotrope liquid (for example, a polyhydric alcohol). It has been disclosed. Further, Patent Document 3 discloses a three-layer cosmetic in which an oil, water, a polyhydric alcohol, a nonionic activator, and a water-soluble salt are blended.
However, these three-layer cosmetics also contain alcohol as an essential component, and cause irritation to skin and eyes.
Accordingly, an object of the present invention is to provide a three-layer cosmetic having a simple structure and a stable interface.

The present inventors have conducted intensive studies on a three-layer cosmetic having a stable interface. As a result, surprisingly, (A) a non-polar oil component, a polar oil component having an IOB value of 0.175 or less, or an IOB value of 0. It has been found that a three-layer cosmetic can be obtained by using a mixed oil component (B) of 175 or less and water (C) bisethoxydiglycol cyclohexane-1,4-dicarboxylate. Further, by adding an inorganic salt, an organic salt, an amino acid, an organic acid, a 1,2-alkanediol having 5 to 8 carbon atoms, betaine, or niacinamide, a three-layer cosmetic having a stable interface is obtained. I found that I can do it.
The present invention is based on these findings.
Therefore, the present invention
[1] (A) Nonpolar oil component, polar oil component having an IOB value of 0.175 or less, or mixed oil component having an IOB value of 0.175 or less, (B) water, and (C) bisethoxycyclohexane-1,4-dicarboxylate Three-layer cosmetics, including diglycol,

  According to the three-layer cosmetic of the present invention, a three-layer cosmetic having a stable interface can be provided. Further, according to the three-layer cosmetic of the present invention, since the amounts of water and oil can be adjusted in a wide range, the ratio of the three-layer structure can be freely controlled. Further, by adjusting the amount of water and selecting the oil content, it is possible to produce cosmetics having a wide range of use feeling. Further, since the three-layer cosmetic of the present invention does not contain a specific surfactant as an essential component, various surfactants can be used. Therefore, the optimal oil, sugar, sugar alcohol, and nonionic surfactant can be selected according to the type of the cosmetic. That is, the three-layer cosmetic of the present invention can be applied to various cosmetics (for example, makeup remover, lotion, serum, marsage oil, bath salt, or dry shampoo).

  The three-layer cosmetic of the present invention comprises (A) a non-polar oil component or a polar oil component having an IOB value of 0.175 or less (hereinafter sometimes referred to as component A), (B) water (hereinafter referred to as component B). ), And (C) bisethoxydiglycol cyclohexane-1,4-dicarboxylate (hereinafter sometimes referred to as component C).
