2. Description of the Related Art An emulsifier is generally used to form a water-in-oil (W / O) emulsified cosmetic in which water is dispersed in oil of a continuous phase. Conventionally, a polyhydric alcohol fatty acid ester activator such as glycerin fatty acid ester or sorbitan fatty acid ester or a polyoxyalkylene-modified organosiloxane activator has been generally used. In general, an aqueous phase component contains 50% by weight or more in the composition. In the high internal water phase W / O emulsion, the oil phase, which is a continuous phase, tends to separate at low temperatures due to the aggregation of water droplets.
Particles increase due to coalescence of water droplets and settle, and oil phase separation in which the upper layer contains only oil tends to occur.

In order to improve the instability due to temperature, there is a proposal to increase the viscosity by blending a large amount of wax. However, this method is not perfect in terms of stability at high temperatures, and is not perfect. It was enough. Also, W / O
A type emulsion has advantages such as protection of skin and imparting of flexibility since the external phase is an oil component, but is sticky at the time of use,
There were problems in usability such as the weight of elongation and hardness.

In order to improve such usability, it is desirable to select and blend a preferred oil from a wide range of oils from polar oils to non-polar oils with a high internal water phase ratio. For alcoholic fatty acid ester-based activators, to obtain a stable oil-in-water type emulsified cosmetic in a system containing a polar oil, and for polyoxyalkylene-modified organopolysiloxane-based activators, in a system containing a nonpolar oil. Could not. Therefore, in the conventional water-in-oil type emulsified cosmetics, there is a restriction in selecting an oil component, and as a result, it has not been possible to give a wide feeling in use.

As for the crosslinked polyether-modified silicone of the formula (I) used in the present invention, a paste-like polyether-modified silicone composition obtained by kneading the silicone oil with a silicone oil under a shearing force has recently been developed. A technique for producing a water-in-oil type emulsion composition having excellent stability over time and feeling of use using the composition has already been proposed (JP-A-6-40847).

[0006]

The present inventors have also conducted research and development of a high internal water phase water-in-oil type emulsified cosmetic, and under such circumstances, the above-mentioned crosslinked polyether-modified silicone and Focusing on the properties of the paste-like polyether-modified silicone compositions, an attempt was made to produce a high internal water phase oil-in-oil emulsified cosmetic composition having excellent usability and stability by using them. As a result, in the high internal water phase water-in-oil emulsified cosmetic in which the above-mentioned paste-like polyether-modified silicone composition is blended as an emulsifier, the hair or skin is moisturized, moist, non-sticky, and lightly spreadable. As for the usability, it was found that sufficient characteristics could not be obtained.

Therefore, the present inventor further studied and found that the above-mentioned emulsifier, in particular, a cross-linked polyether-modified silicone and a specific component usability improver were used in combination to form a water-in-oil type emulsifier. By forming cosmetics, a wide range of oils from polar oils such as triglycerides, ester oils and hydrocarbon oils to non-polar oils can be stably emulsified, moisturizing the skin and hair, moisturizing, It has been found that a water-in-oil type high-internal-water-phase emulsified cosmetic composition having no stickiness, light spreading, and good stability over time and having an aqueous phase component content of 50.0% by weight or more is formed. did it.
Therefore, the present invention provides a highly internal aqueous phase oil that moisturizes the skin and hair, is moist, has no stickiness, is light, and has excellent stability over time, that is, has excellent usability and stability. An object of the present invention is to provide a water-type emulsified cosmetic, and an object thereof is to provide the cosmetic.

[0008]

The present invention can provide a high internal water phase water-in-oil emulsion cosmetic.

[0012]

Embodiments of the present invention will be described below. The high internal aqueous phase water-in-oil emulsified cosmetic according to the present invention means that the content of the aqueous phase component is 50.0% by weight or more of the total composition, and the aqueous phase component is a continuous phase oil phase component. It refers to a dispersed water-in-oil (W / O) emulsified cosmetic. Specific cosmetics include, for example, emulsions, skin creams,
There are milky or creamy products such as hair creams, liquid foundations, eye liners, mascaras, eye shadows, etc., but the cosmetics of the present invention are not limited to those exemplified, but in the oil described above. As long as it is a water-type emulsified cosmetic, it falls under the cosmetic of the present invention.

The cross-linked polyether-modified silicone used as an emulsifier in the present invention is a polymer obtained by cross-linking methyl hydrogen polysiloxane with diallyl polyether at both ends.
No. 72932 or JP-A-5-140320 can be used. In the present invention, a product produced thereby can be used, or a commercially available product may be used.

As the crosslinked polyether-modified silicone, it is preferable to use a paste-like polyether-modified silicone composition previously kneaded with silicone oil under a shearing force. Oil or the like may be blended as a cosmetic component. It is also possible to mix and knead the polyether-modified silicone and the silicone oil, if necessary, after blending them with other cosmetic ingredients.

In using the crosslinked polyether-modified silicone of the structural formula (I) in the present invention, 1 is 3
~ 20 is preferred. If it is less than 3 and deviates from this range, the paste composition obtained by kneading the crosslinked polyether-modified silicone and the silicone under shearing force has poor emulsifiability of water. The swelling property is insufficient, which is not preferable. And m is 10-2
00 is preferable, and when it is less than 10, the silicone oil does not sufficiently swell, and when it exceeds 200, the paste composition obtained by kneading with the silicone oil under a shearing force has poor emulsifiability of water.

Further, n is preferably 1.0 to 10.0,
When it is smaller than 1.0, a three-dimensional structure cannot be formed, and the mixture does not become a paste even when kneaded with silicone oil, and the emulsifiability of water is poor. Conversely, if it exceeds 10, the crosslink density of the three-dimensional structure becomes too high, so that the silicone oil cannot be retained even when kneaded with the silicone oil, and a stable paste is not obtained, which is not preferable.

In the present invention, the silicone oil to be kneaded with the crosslinked polyether-modified silicone is not particularly limited, and may be linear or branched. Although possible, a low-viscosity silicone oil having a viscosity at 25 ° C. of 100 mPa · s or less can be preferably used. Specific silicone oils that can be used include methylpolysiloxane, methylphenylpolysiloxane, ethylpolysiloxane, ethylmethylpolysiloxane, ethylphenylpolysiloxane, octamethylcyclotetrasiloxane,
Cyclic dimethylpolysiloxanes such as decamethylcyclopentasiloxane;
You may mix and use more than one kind.

As described above, the mixing ratio of the crosslinked polyether-modified silicone to the silicone oil is preferably 10 to 1,000 parts by weight, more preferably 2 to 100 parts by weight of the crosslinked polyether-modified silicone.
0 to 500 parts by weight is preferred. When the amount of the cross-linked polyether-modified silicone is less than the above range, a stable and good gel structure cannot be maintained, and when the amount exceeds the above range, the weight is felt on the skin and the usability and usability deteriorate. Not preferred.
The apparatus for performing the kneading treatment under a shearing force is not particularly limited, and a commonly used apparatus can be used. Examples thereof include a three-roll mill, a two-roll mill, a sand grinder, a colloid mill, and a Gaulin homogenizer. Among them, a three-roll mill can be particularly preferably used.

The amount of the crosslinked polyether-modified silicone used as an emulsifier in the present invention is preferably 0.1 to 10.0% by weight based on the total amount of the cosmetic. If it is less than 0.1% by weight, the aqueous phase component of 50.0% by weight or more of the internal phase cannot be emulsified. Conversely, if it exceeds 10.0% by weight, the elongation is poor and the feeling of use becomes poor. Also becomes heavy, which is not preferable. When the cross-linked polyether-modified silicone is blended as a paste-like polyether-modified silicone composition, it is preferable to select the amount of the cross-linked polyether-modified silicone in the above range.

As the oil phase component to be incorporated into the high internal water phase water-in-oil type emulsion cosmetic composition of the present invention, an oil agent which is usually used in a water-in-oil type (W / O type) emulsion cosmetic composition, The oil phase component can be used without any particular limitation, and any of natural and vegetable oils and synthetic oils can be used. As the oil phase component, specifically, liquid paraffin, liquid such as squalane, paste or solid hydrocarbon, wax, higher fatty acid, higher alcohol, ester, glyceride, or dimethylpolysiloxane, or polyether modified, Examples include silicone-based oils such as various modified silicones such as fluorine-modified.

In the emulsified cosmetic of the present invention, the oil phase component is contained in the cosmetic in an amount of from 10% by weight to 50% by weight based on the total amount of the cosmetic.
It is blended in a range of less than weight%. If it is less than 10% by weight,
It is difficult to make water-in-oil type cosmetics, 50% by weight
If the above amount is blended, the amount of water in the internal phase becomes too small, and it is not preferable because of lack of moisture in terms of usability. In addition, as the oil corresponding to "O" in the W / O type emulsified cosmetic, all oily components such as natural animal / vegetable oil, synthetic oil and the like contained in the cosmetic correspond to, The crosslinked polyether-modified silicone which is an emulsifier and the paste-form polyether-modified silicone composition which is a preferable form thereof are also oily components, and are components corresponding to “O”.

The water phase component such as water mixed with the oil phase component in the high internal water phase water-in-oil type emulsified cosmetic of the present invention, that is, "W" means a water-soluble component such as water, ethanol or a thickener. Compounds are applicable, and water-soluble polymers, inorganic salts and amino acid salts to be blended as a usability improver are also water phase components and correspond to “W” in the present invention. In the present invention, the amount of the aqueous phase component is from 50% by weight to less than 90% by weight based on the total amount of the cosmetic. The blending amount of water itself is preferably 60% by weight or more.
This is preferable because a moist feeling can be imparted.
If the amount of the aqueous phase component is less than 50% by weight, the characteristic of water is hardly exhibited and lacks moist feeling. Conversely, if the content is 90% by weight or more, it is difficult to obtain a water-in-oil type.

Next, components to be blended as a usability improving agent in the present invention will be described. As described above, the component to be blended as the usability improver is one or more selected from the group consisting of a water-soluble polymer having a molecular weight of 2,000 to 300,000, an inorganic salt and an amino acid salt.

The water-soluble polymer has a molecular weight of 2,000 to 300,000, preferably 3,000, as described above.
~ 100,000 is good. Those having a molecular weight of less than 2000 do not contribute to improvement in usability. On the other hand, when the molecular weight exceeds 300,000, there is a disadvantage that the contribution of improvement in usability is small and the feeling of use of the emulsified cosmetic is sticky. The compounding amount is 0.1 to 20.0% by weight, preferably 0.2 to 10.0% by weight of the total amount of the emulsified cosmetic. 0.1% by weight
If it is less than 20.0% by weight, the usability cannot be improved, and if it exceeds 20.0% by weight, it becomes unfavorable because it becomes sticky when used as an emulsified cosmetic.

Particularly preferred among the water-soluble polymers are:
Polyethylene glycol, which is particularly effective in improving the usability of emulsified cosmetics over others, and has the advantage that the feeling of use when used as an emulsified cosmetic is preferred. The particularly preferred molecular weight of polyethylene glycol is 3,000 to 20,000, and the compounding amount is preferably 1 to 10.0% by weight based on the total amount of the emulsified cosmetic.

Among them, the inorganic salts are particularly preferably sodium chloride, potassium chloride, magnesium chloride, calcium chloride, aluminum chloride, sodium sulfate, potassium sulfate, magnesium sulfate, and aluminum sulfate. When the inorganic salt is used as the usability improver in the present invention, the amount is 0.1 to 8.0% by weight, preferably 0.2 to 8.0% by weight.
It is 5.0 weight. If it is less than 0.1% by weight, the usability of the emulsion cannot be improved, and if it exceeds 8.0% by weight, the effect is not enhanced.

In the present invention, the amino acid salt to be compounded as a usability improving agent is one in which a carboxyl group or an amino group in an amino acid forms a salt, and a water-soluble amino acid salt can be used without any particular limitation. For example, sodium aspartate, potassium aspartate,
