2. Description of the Related Art In conventional emulsified cosmetics, an oil phase and a water composed of non-volatile oils such as non-volatile hydrocarbons, oils and fats, higher alcohols, higher fatty acids and esters are used. An emulsion obtained by emulsifying a phase with a surfactant has been applied to cosmetics. In general, an emulsified cosmetic has a refreshing feeling due to evaporation of water in the emulsified cosmetic at the time of application and gives a refreshing feeling to the skin, and a residual oil agent protects the skin and gives a moisturizing feeling. Therefore, it is said to be one of the excellent cosmetic forms.

However, since the above-mentioned non-volatile oil agent remains on the hair when it is applied to the skin, hair, etc., it has a drawback that stickiness is noticed and a slimy and unpleasant feeling remains forever. Was. Therefore, in recent years, by using a volatile oil agent such as a low-boiling point hydrocarbon or a low-boiling point silicone oil in the emulsified cosmetic as a part of the oil phase, an emulsified cosmetic in which the undesired feel due to the residue of the oil is reduced Proposed. As a water-in-oil emulsion containing a volatile oil agent such as low-boiling point hydrocarbon or low-boiling point silicone oil, for example, JP-A-61-263631 is known. However, when powder is blended as a colorant into an emulsified cosmetic containing a volatile oil agent such as low boiling point hydrocarbon or low boiling point silicone oil as a makeup cosmetic agent, etc., the volatile oil agent evaporates after coating. As a result, the ratio of the powder and oil agent remaining on the skin or hair changes, and the ratio of the powder increases. Therefore, even if the feeling of use and the finish are both good immediately after application, the powder will change from being wet with the oil agent to being dry in a short time after application (relatively).
The scattering of light on the surface of the powder increases and the finished color becomes whitish. Further, when sebum is secreted with the passage of time, the powder gets wet with sebum, and the scattering of light on the surface of the powder decreases, resulting in a darker finish color, which is not desirable called dullness. It had a defect that a phenomenon occurred.

Further, it is known to add plate-like boron nitride or synthetic mica as a powder with little color change of itself when wet or dry for the purpose of preventing dullness in makeup cosmetics. (JP-A-61-1)
No. 00508, JP-A-63-185810). However, even if these powders are used in emulsified cosmetics, the color change does not occur completely,
Further, since it is impossible to prevent the color change of other colorants to be blended at the same time, it is not satisfactory as a dull emulsified cosmetic.

On the other hand, as a plate-like silicon dioxide powder containing fine particles of titanium oxide, in JP-A-1-143821 and JP-A-6-116119, it has been proposed to blend it into cosmetics from the viewpoint of the effect of preventing ultraviolet rays. However, all of them are related to solid powder cosmetics, and a refreshing feeling due to evaporation of water is not imparted, resulting in lack of a refreshing feeling of use.

Therefore, the object of the present invention is to reduce the change in the color of the finished product immediately after coating and to have a high effect of suppressing dullness.
An object of the present invention is to provide an emulsified cosmetic which is excellent in refreshing feeling and has no stickiness.

Means for Solving the Problems As a result of intensive studies by the present inventors, an emulsified cosmetic containing (A) a specific volatile oil agent and (B) a plate-like silicon dioxide powder containing fine titanium oxide particles. It has been found that the material can achieve the above-mentioned object.

The present invention was made based on the above findings, and provides an emulsified cosmetic containing the following components (A) and (B). (A) One or more volatile oil agents selected from the group consisting of low boiling hydrocarbons and low boiling silicone oils (B) Plate-like silicon dioxide powder containing fine particles of titanium oxide

The emulsified cosmetic composition of the present invention will be described in detail below.

The component (A) used in the present invention is one or more volatile oil agents selected from the group consisting of low boiling hydrocarbons and low boiling silicone oils.

The low boiling point hydrocarbon has 6 to 6 carbon atoms.
Preferred are 15, especially 8 to 15 straight-chain, branched or cyclic hydrocarbons. Among the above low boiling point hydrocarbons, carbon number is particularly 1
0 to 13 isoparaffins are preferable, and these isoparaffins are superior to other volatile oil agents in terms of ease of emulsification and stability after emulsification. The low boiling point hydrocarbon preferably has a boiling point of 240 ° C. or less in the atmosphere. As the low boiling point hydrocarbon, a commercially available product may be used, and as a specific example, Isobar C (ESS
O), shell sol 71 (Shell) and the like.

The viscosity of the low boiling point silicone oil is 25 ° C.,
It is preferably less than 10 c.s., particularly preferably 5 c.s. or less. A commercially available product may be used as the low boiling point silicone oil, and specific examples thereof include SH244 and SH245 (Toray.
Dow Corning), KF96L-2cs, KF96L-
1 cs (Shin-Etsu Silicone) and the like.

In the present invention, other oil agents may be used in combination with the volatile oil agent [component (A)], if necessary. The above-mentioned other oil agents may be those used in ordinary emulsified cosmetics, and include, for example, hydrocarbons (other than the above volatile oil agents [component (A)]), oils and fats, waxes and higher alcohols. , Higher fatty acids, esters, and the like. One or two of these may be used depending on the application.
Used in combination of two or more species.

The content of the above volatile oil agent (component (A)) is preferably 0.5 to 6 in the entire emulsified cosmetic composition of the present invention.
0% (% is based on weight, the same applies hereinafter), more preferably 1 to
55%, most preferably 2-50%. If the content is less than 0.5%, it becomes impossible to satisfy the refreshing feeling of use and non-stickiness, while
If it exceeds 60%, the amount of the oil agent becomes too much and the refreshing feeling due to the evaporation of water decreases, which is not preferable as an emulsified cosmetic. In addition, the volatile component in the present invention [above (A)
The content of the component and the volatile component of the other oil agent] is preferably 5% or more, more preferably 10% or more in the entire oil agent containing the component (A) and the other oil agent.

The form of the plate-like silicon dioxide powder containing the fine particle titanium oxide which is the component (B) used in the present invention is not limited to the form of a composite in which the fine particle titanium oxide is dispersed in the plate-like silicon dioxide powder. A multi-component system in which titanium oxide and plate-like silicon dioxide powder are uniformly mixed may be used. By controlling the particle size of the fine particle titanium oxide, a higher dullness suppressing effect can be obtained by utilizing light scattering on the surface of the fine particle titanium oxide. Therefore, the plate-like dioxide containing fine particle titanium oxide in the form of the above complex is obtained. It is preferable to use silicon powder.

The fine titanium oxide particles have an average particle size of preferably 10 to 1000 nm, more preferably 10 to 30 nm.
It is 0 nm. If the average particle size is less than 10 nm, the transparency of the fine particle titanium oxide becomes too high, and the effect of increasing whiteness when wet with sebum is insufficient, while 1
If it exceeds 000 nm, it tends to be difficult to obtain a powder in the form of a composite uniformly dispersed in the plate-like silicon dioxide powder.

Plate-shaped silicon dioxide powder [component (B)]
The content of fine particle titanium oxide in is preferably 1 to
It is 60%, more preferably 5 to 50%. If the content is less than 1%, the dullness suppressing ability is not sufficient, while if it exceeds 60%, the volatile oil agent evaporates immediately after coating and the powder becomes slightly dry. The whiteness becomes too high, and the dullness suppressing ability also decreases.

In addition, various properties may be improved by adding a component other than the particulate titanium oxide and the plate-like silicon dioxide to the plate-like silicon dioxide powder [component (B)] containing the particulate titanium oxide. However, the total amount of the fine particle titanium oxide and the plate-like silicon dioxide must be 80% or more from the viewpoints of the dullness suppressing ability and the stability of the plate-like silicon dioxide powder containing the fine particle titanium oxide. Examples of other components (less than 20%) that can be added to the plate-like silicon dioxide powder containing fine particle titanium oxide include iron oxide, alumina, and zirconia.

Plate-shaped silicon dioxide powder [component (B)]
The average particle diameter of is preferably 1 to 100 μm, more preferably 1 to 40 μm, and most preferably 1 to 30 μm. When the average particle diameter is less than 1 μm, slipperiness is deteriorated and spreadability on the skin is deteriorated, and the emulsified cosmetic intended by the present invention cannot be obtained. On the other hand, 100 μm
When it exceeds the above range, a rough and uncomfortable feeling is generated on the skin, which is not preferable as an emulsified cosmetic.

Plate-shaped silicon dioxide powder [component (B)]
The thickness of the particles is preferably 0.03 to 3 μm, more preferably 0.05 to 2 μm, and most preferably 0.08 to
It is 1 μm. When the thickness of the particles is less than 0.03 μm, it becomes difficult to uniformly disperse the fine particle titanium oxide,
The plate-like silicon dioxide powder containing fine particle titanium oxide according to the present invention cannot be obtained. On the other hand, when the particle size exceeds 3 μm, it becomes difficult to prepare a plate-like particle shape. It is not possible to obtain the plate-like silicon dioxide powder.

Plate-shaped silicon dioxide powder [component (B)]
The content of is preferably 0.1 to 50%, more preferably 0.3 to 40%, and most preferably 0.5 to 30% in the entire emulsified cosmetic composition of the present invention. When the content is 0.
If it is less than 1%, the effect of suppressing dullness will not be exhibited, while if it exceeds 50%, the amount of powder components will be too much and the cosmetic coating film will become powdery, which is not preferable as an emulsified cosmetic.

In the present invention, the content ratio of the component (A) to the component (B) is (A) / (B) in terms of weight ratio.
Is preferably 0.01 / 1 to 80/1, more preferably 0.05 / 1 to 40/1. The ratio of the above contents is
If it is less than 0.01 / 1, the ratio of the plate-like silicon dioxide powder containing fine particle titanium oxide becomes too large and becomes powdery, while if it exceeds 80/1, the plate-like silicon dioxide powder containing fine particle titanium oxide is contained. Since the ratio of the silicon dioxide powder becomes too small, it is not possible to prevent the color change of the finish, which is not preferable.

The plate-like silicon dioxide powder containing fine particle titanium oxide, which is the component (B), may be appropriately subjected to a hydrophobizing treatment depending on the purpose of the emulsified cosmetic composition serving as a control for compounding.
