Description

  The present invention relates to a water-in-oil type emulsified cosmetic.

In the water-in-oil type emulsified cosmetic, the aqueous component and the oil component are stably mixed by the emulsifying action of the surfactant incorporated. However, since the surfactant is a highly sticky substance, it is desirable to reduce the amount of the surfactant in order to obtain a good feeling in use.
Emulsions produced by adsorbing powder at the interface without using a surfactant are known as Pickering emulsions. Conventionally, cosmetics using such a Pickering emulsion have been studied.
For example, Patent Document 1 discloses a water-in-oil emulsion composition containing 1 to 40% by mass of a powder component that is not dispersed in water, 0.001 to 1% by mass of a hydrophilic surfactant, an oil phase component and a water phase component. However, it is described that it has excellent emulsion stability and little sticky feeling. Patent Document 2 discloses (A) a fluorinated oil, (B) a powder coated with a compound containing a fluorine compound, (C) an oil incompatible with component (A), and (D) an organically modified clay mineral. And (E) a phase containing a fluorine-based oil and an aqueous phase dispersed in an oil phase containing a water-phase component in a specific ratio and containing an oil that is incompatible with the fluorine-based oil (F + W) / O It is described that a type emulsion does not require the use of a surfactant, has excellent emulsification stability, has a long lasting cosmetic effect, and gives a fresh feeling when applied to the skin.

Such a water-in-oil emulsified cosmetic of a pickering emulsion has a low surfactant content, so that the stickiness of the skin after application is reduced.
However, the present inventor has found a problem that when applying the cosmetic with a finger or a sponge, streak-like unevenness (streak unevenness) is observed. When streak unevenness is observed, a uniform and natural finish is impaired. When a foundation or the like is applied repeatedly, unevenness is caused, resulting in an unnatural finish. Streak unevenness can be applied evenly by repeating it many times, but it takes time and also reduces the amount of applied cosmetic on a certain area on the skin. Resulting in.
In addition, the water-in-oil emulsified cosmetic of the pickering emulsion has a problem that natural luster cannot be obtained.
