The liquid cosmetics in this case include body lotions, hair liquids, hair tonics, hair lotions, sun oils, and the like.

多層型の化粧料が見直されてきている。
Conventionally, liquid cosmetics basically composed of an oil phase and an aqueous phase have been known to include emulsion and solution types, as well as multilayered cosmetics in which multiple types of oil are dispersed in the aqueous phase. However, emulsion-type and solution-type products have the disadvantage of requiring a large amount of surfactant, and the use of surfactants may cause skin irritation compared to other ingredients such as oil. These problems include the problem that the surfactant itself tends to cause problems, and the decomposition of the surfactant itself tends to cause problems such as destabilization of the system and the generation of a bad odor. Recently, research on surfactants has been widely conducted in various fields, and surfactants with high stability and safety have been developed, but nothing perfect has yet been found. Therefore, at present, it is considered that there is nothing better than making cosmetics without using surfactants, and from this perspective, the multilayer cosmetics mentioned above have been reconsidered. There is.
ところで、従来、多層型の化粧料としては、二

未だ不十分であるという欠点があり、一方、複数
油分からなる場合でも、これらの油分は混和物の
状態となつているため、各油分の持つ特有の効果
が十分に発揮されないという欠点がある。 By the way, two-layer type and three-layer type cosmetics are conventionally known as multi-layer cosmetics. In a two-layer type, the oil layer consists of a single oil or a mixture of multiple oils, but if it consists of a single oil, the feeling of use, texture, and moisturizing effect on hair and skin will be affected by the single oil. Because it is limited to things that arise from
There is a drawback that it is still insufficient, and on the other hand, even when it is composed of multiple oil components, these oil components are in the state of a mixture, so there is a drawback that the unique effects of each oil component are not fully exhibited.
また、従来の三層型化粧料は、2種の油分から

ば、ムラ状に付着し、それぞれの油分の持つ効果
を充分に発揮させることができない。 In addition, in conventional three-layer cosmetics, an oil phase and an aqueous phase consisting of two types of oil are simply separated into three layers due to the difference in specific gravity.
Since the seed oils are separately made into fine particles, when applied to hair or skin, the inventors' confirmation tests show that they adhere unevenly, making it difficult to fully demonstrate the effects of each oil component. Can not.
本発明者らは、従来技術に見られる前記欠点を
克服すべき鋭意研究を重ねた結果、液体化粧料と
して好適な新規な三層型液体を見出し、本発明を
完成するに到つた。
As a result of intensive research to overcome the above-mentioned drawbacks found in the prior art, the present inventors discovered a novel three-layer liquid suitable as a liquid cosmetic and completed the present invention.
即ち、本発明によれば、油相と水相とからな
り、該油相は水相に対する拡張係数が共に負の値

That is, according to the present invention, the three-layer liquid is composed of an oil phase and an aqueous phase, and the oil phase is composed of two types of oil, both of which have negative expansion coefficients with respect to the aqueous phase. The specific gravity of the oil phase is adjusted to be approximately equal to or slightly heavier than that of the water phase, and the two types of oil components that make up the oil phase are immiscible and combine while retaining each oil layer to form water. A three-layer liquid is provided which is characterized by the formation of oil phase spheres in the phases.

The oil content of the seeds is dispersed, but in this case, unlike in the conventional case, the oil content of the two types is not mixed;
It is characterized in that each oil layer is combined while retaining its properties to form an oil phase spherical body. Therefore, in the case of the present invention, since each oil component is not mixed, a unique effect derived from each oil component can be obtained, and by using this as a cosmetic base material,
It is possible to obtain a liquid cosmetic that is extremely comfortable to use and has extremely good moisturizing properties for skin and hair. Such a liquid cosmetic was discovered for the first time by the present inventors, and is extremely unique, going beyond conventional wisdom.

The above γ 1 and γ 2 are usually On the other hand, γ3 is the interfacial tension when alcohol is added to the oil/water system, and
It can be determined by interpolation from the interfacial tension value when water is added to the oil/alcohol system, but in general, it can be determined using the FMFowkes formula γ 3 = γ 2 + γ 1 −

電解質の適当量を選択すればよい。 In order to produce the three-layer liquid of the present invention, an oil phase liquid consisting of a first oil component and a second oil component may be injected into an aqueous phase. In this case, water is usually used as the aqueous phase, but water mixed with an appropriate amount of a water-miscible organic solvent can also be used. Such a water-miscible organic solvent is used as a specific gravity regulator for the aqueous phase or as an oil expansion coefficient (S) regulator. Organic solvents preferably used for this purpose include alcohols such as ethyl alcohol, propyl alcohol, isopropyl alcohol, butyl alcohol, isobutyl alcohol, and t-butyl alcohol. Of course, other organic solvents such as glycerin, propylene glycol, butylene glycol, ethylene glycol, acetone, etc. can be applied as well. When using an aqueous phase containing alcohol, the alcohol content is preferably 70% by weight or less based on the aqueous phase, taking into account the solubility of oil in the aqueous phase. In addition, in the aqueous phase, in order to adjust the recombination time after shaking and dispersion, electrolytes such as sodium salts such as sodium sulfate and sodium chloride, magnesium salts such as magnesium sulfate and magnesium chloride, ammonium sulfate, ammonium chloride, etc. It is advantageous to add ammonium salts, calcium salts, potassium salts, lithium salts, iron salts, copper salts, cobalt salts, chromium salts, aluminum salts, organic acid salts, urea, amino acids, etc. The higher the electrolyte concentration, the shorter the recombination time. In cosmetics, it is usually added to the aqueous phase in an amount of 0.01 to 5%. Of course, if the amount of electrolyte is less than this, recombination will occur even if there is no electrolyte at all. An appropriate amount of electrolyte may be selected according to the purpose of the product.

適用される。 When the liquid cosmetic container accommodating body of the present invention as shown in FIGS. 1 to 3 is vibrated up and down several times during use, the oil phase spheres 3 are divided into fine particles and dispersed. However, in this case, the oil layer structure is extremely unique in that the first oil component and the second oil component do not substantially mix, but maintain a spherical structure that maintains each oil layer. manifest the effect of Moreover, this dispersed state is maintained for a relatively long time, usually about 10 to 30 minutes. Therefore,
The liquid cosmetics of the present invention are particularly advantageously applied as liquid cosmetics that are used for a long time, such as body lotions, hair liquids, hair tonics, and hair lotions.

与することができる。 In the liquid cosmetic of the present invention, since the oil phase is present in the aqueous phase, oil and other components that are easily oxidized by air can be stably blended. That is, the oil phase is completely blocked from contact with air by the aqueous phase, and the interfacial area between the large spherical oil phase and the water phase is extremely small compared to emulsified cosmetics. Because of this, the components in the oil phase are extremely unlikely to be affected by oxidation by air or by the aqueous phase. Furthermore, in the cosmetic composition of the present invention, the added fragrance etc. are distributed between the oil phase and the aqueous phase according to their solubility, so that the top note, middle note, and base note can be given more effects than conventional ones. .

た。 Next, by manually vibrating the containers for each of the three-layer liquid cosmetics obtained in Examples 1 to 3 up and down several times, the oil phase spherules were dispersed into fine particles (approximately in diameter). When this state was left still for about 10 to 30 minutes, the fine particles gradually coalesced and grew into one oil phase spherical body again.
