Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a water-in-oil type (W / O)
Type) emulsified composition. More specifically, the present invention relates to a water-in-oil type emulsified composition which gives a refreshing feeling of use and is excellent in emulsification stability.

[0002]

2. Description of the Related Art Various emulsified cosmetics such as skin care creams, massage creams, sunscreen lotions, foundations, eyeliners, mascaras and the like can be mentioned. These are classified according to emulsification type. Oil-in-water (O / W type) emulsified cosmetics and water-in-oil type (W / O type)
It is roughly divided into emulsified cosmetics.

[0003] Emulsified cosmetics contain more water in their components than oil-based cosmetics, so they give a refreshing feeling when applied to the skin and further suppress the oily feeling. In addition, many of them are liquid or creamy and have properties such as good spreadability on the skin and easy to obtain a uniform finish without unevenness.

[0004] In particular, W / O type cosmetics have a higher microbial resistance than O / W type cosmetics since the oil phase is a continuous phase (external phase). Leaves a low oil film, protects the skin from drying for a long time, and hardly causes re-emulsification even if it comes in contact with water by water bathing, water work, sweating, etc. Has excellent performance.

[0005]

However, it is difficult for conventional W / O type cosmetics to obtain a stable emulsification,
In order to achieve stabilization, the amount of water contained in the dispersed phase (inner phase) is often limited, or a solid oil component is blended in the dispersed phase. There was a drawback that the feeling and oiliness were strong.

On the other hand, from the viewpoint of usability, it is necessary to reduce the amount of oil components and to use an oil component with low tackiness in order to obtain a light feeling in the emulsified system with less tackiness. Particularly, liquid oil is suitable as an oil component of W / O type cosmetics because it forms a uniform thin film on the skin and gives a smooth feeling without stickiness.
When the oil component composed of these liquid oils is used for the dispersed phase, the surfactant which is usually used as an emulsifier in emulsified cosmetics has poor emulsifiability, and it is difficult and stable to obtain a uniform and fine emulsified system. It was difficult to obtain a suitable emulsion.

[0007] That is, W / O type cosmetics containing liquid oil are superior to O / W type emulsified cosmetics in terms of ease of use and high in palatability, but provide a stable emulsion. At present, it is not widely used as a cosmetic because it is difficult.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a W / O type emulsifier which has high stability, has an excellent refreshing sensation, and which is refreshing after application and has good makeup. It is to provide a composition.

[0009]

Means for Solving the Problems The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, using a specific nonionic surfactant as an emulsifier, an oil phase comprising a liquid oil component was used.
By adding an aqueous phase containing a certain concentration of an organic acid salt, an amino acid, and a salt thereof under stirring, the aqueous phase is stably emulsified for a long time, has no stickiness at the time of application, and is hard to lose makeup after application. It has been found that an O-type emulsion composition can be obtained, and the present invention has been completed.

In the present invention, those obtained by subjecting these powder components to a hydrophobic treatment are used.

The hydrophobic treatment method may be any method as long as it can impart water repellency, and the method is not limited. For example, a gas phase method, a liquid phase method, an autoclave method,
An ordinary surface treatment method such as a mechanochemical method can be used.

For example, when the treatment is carried out by adding a hydrophobizing agent to the raw material powder, it may be diluted with an appropriate solvent (dichloromethane, chloroform, hexane, ethanol, xylene, volatile silicone, etc.) and added. You may add directly. For mixing and stirring the powder and the treating agent, a ball mill, a Hogersight ball mill, a vibration ball mill, an attritor, a pot mill, a rod mill, a pan mill, a homomixer, a homodisper, a Henschel mixer, a Nauter mixer, and the like can also be used.

The hydrophobic powder has a strong water repellency, is resistant to water and sweat even when actually applied to an emulsion, and has a long lasting effect because makeup is most unlikely to be lost. The emulsified particles are dense and have the longest stability.

One of these hydrophobic powders may be used,
Alternatively, two or more kinds may be used. In addition, any hydrophobic powder that can be applied to general cosmetics may be used, and is not limited to the components exemplified above.

When a powder that is not a hydrophobic powder (such as an untreated powder) is used, a relatively stable emulsion can be obtained. However, since the powder surface has a strong hydrophilicity, makeup loss due to water or sweat may occur. Very easy to get up.

The amount of the component (D) is preferably from 3.0 to 60.0% by weight, more preferably from 5 to 40.0% by weight, in the water-in-oil emulsion composition of the present invention. If the amount is too small, the coloring is poor and the composition is unsuitable as a cosmetic. On the other hand, if the amount is too large, the powderiness is remarkable and the stability tends to be poor.

The water-in-oil emulsion composition of the present invention is prepared, for example, as follows.

First, the component (A) is added to the oil phase containing the component (B), and the mixture is heated and stirred. Next, after the component (A) is dispersed, an aqueous phase containing the component (C) is added little by little, and further stirred to obtain a target water-in-oil emulsion composition. If necessary, the component (D) may be further added and stirred to obtain a powder-containing emulsified cosmetic.

In the above method, as long as the component (A) is soluble in the component (B), any temperature from 5 to 90 ° C. can be selected as the production temperature. A composition can be obtained.

The water-in-oil emulsion composition of the present invention thus obtained is characterized in that it is very stable when left standing or shaken, but can be easily prepared by thinning the solution to give a light shear. Is to be destroyed. This indicates that the same phenomenon occurs when actually applied to the skin.Thus, while it is a water-in-oil type, emulsification destruction occurs immediately at the time of application, the aqueous phase comes into contact with the skin, and a refreshing feeling is felt. Feeling, good spread,
It is thought to give a refreshing feeling without stickiness.

When the water-in-oil emulsion composition of the present invention is allowed to stand for a long period of time, the oil component layer may be slightly separated at the top. However, if the viscosity is such that it becomes uniform by gentle shaking, it can be used as a shaking type cosmetic.

The water-in-oil emulsion composition of the present invention can be used for cosmetics,
Although it can be widely applied to quasi-drugs, pharmaceuticals, etc., its main performance is that it is clearly perceived as a refreshing usability and difficulty in breaking down makeup, especially for use as sunscreens and foundations preferable.
