Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a water-in-oil type emulsified cosmetic. More specifically, the present invention relates to a high water-in-oil type oil-in-water type emulsified cosmetic which has excellent usability of being non-sticky and lightly spreading, softening skin and hair, and having good stability.

[0002]

2. Description of the Related Art Water-in-oil (W / O type) emulsified cosmetics have been used as cosmetics for protecting skin and hair and providing flexibility.

As emulsifiers for W / O type emulsified cosmetics, polyhydric alcohol fatty acid ester activators such as glycerin fatty acid ester and sorbitan fatty acid ester, and polyoxyalkylene-modified organopolysiloxane activator are generally used. .

[0004]

However, W / O
At low temperatures, the oil phase, which is a continuous phase, tends to separate due to aggregation of water droplets at low temperatures, and at high temperatures, particles increase due to coalescence of water droplets and settle, and the upper layer contains only oil. Oil phase separation easily occurs. This tendency is particularly strong in a W / O emulsion having a high internal water phase in which water is 50% by weight or more of the whole.

In view of the above problems, a method of increasing the viscosity by adding a large amount of wax has been adopted to improve the temperature stability. However, even this method has insufficient stability at high temperatures. Met.

[0006] Further, the W / O type emulsion has an advantage that the external phase is an oily component, such as protection of skin and hair and imparting of flexibility, but it also has stickiness during use, weight of spread, hardness and the like. There was also a problem to be improved in usability.

[0007] In order to improve such usability, it is desirable to select and blend a preferable oil component from a wide range of oil components from polar oils to non-polar oils. In a system containing an oil, and in a system containing a non-polar oil with a polyoxyalkylene-modified organopolysiloxane-based activator, there is a problem that a stable water-in-oil emulsion cosmetic cannot be obtained.

[0008] Therefore, in the conventional water-in-oil type emulsified cosmetic, there is a restriction in selecting an oil component.
There has been a technical problem that it is extremely difficult to have a wide spread in terms of usability.

On the other hand, for example, Japanese Unexamined Patent Publication No.
In Japanese Patent No. 47, a W / O emulsion using a paste-like polyether silicone composition as an emulsifier has been proposed to solve the above-mentioned problems, but the usability such as non-stickiness and lightness of spreadability has been proposed. In this regard, there is a point that is not necessarily sufficient and should be improved.

In view of the above circumstances, the present inventors have made intensive studies to solve the above-mentioned problems, and as a result, as a emulsifier, a specific polyether-modified silicone, a specific high molecular weight silicone and / or a specific amino-modified or ammonium-modified silicone. By adjusting the emulsified composition by combining high-molecular-weight silicones in specific amounts, it is possible to mix a large amount of water, and it has excellent stability, and has excellent usability such as non-greasy, moist, and light growth. Then, they have found that a water-in-oil type emulsified cosmetic having a high internal aqueous phase that imparts a smooth feel to hair and skin can be obtained, thereby completing the present invention.

The present invention has an excellent usability of being non-greasy and lightly spreadable, has a smooth feel to the skin and hair, that is, imparts flexibility, and has a high stability and high stability. It is intended to provide a type emulsion cosmetic.

In the present invention, the crosslinked polyether-modified silicone (A) is obtained by kneading 100 parts by weight of the crosslinked polyether-modified silicone and 10 to 1000 parts by weight of silicone oil under shearing force. It is intended to provide the above-mentioned high internal water phase water-in-oil type emulsified cosmetic, which is blended as a paste-like silicone composition.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail.

Component (A) represented by the above general formula (I)
Is a polymer obtained by cross-linking methyl hydrogen polysiloxane with diallyl polyether at both ends, and acts as an emulsifier.

As the cross-linked 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 producing the paste-like polyether-modified silicone composition, 10 to 1000 parts by weight, preferably 20 parts by weight, of a low-viscosity silicone oil having a viscosity at 25 ° C. of 100 mPa · s or less with respect to 100 parts by weight of the crosslinked polyether-modified silicone.
It is preferable to obtain the low viscosity silicone oil by kneading under a shearing force of about 500 parts by weight. As the paste-like composition, a commercially available product may be used.

If the amount of the silicone oil in the paste composition is less than the above range, a stable and good gel structure cannot be maintained. If the amount exceeds the above range, the weight may be felt on the skin and the feeling of use may be reduced. It is not preferable because it deteriorates.

In the general formula (I), 1 is 3 to 20.
If less than 3, water emulsification is poor,
If it exceeds 20, the swelling property to the silicone oil becomes insufficient.

Further, m must be from 10 to 200. If it is less than 10, it will not swell sufficiently in silicone oil, and if it exceeds 200, the emulsifiability of water will be poor.

Further, n must be in the range of 1.0 to 10.0. If it is smaller than 1.0, a three-dimensional structure cannot be formed, and the emulsifiability of water becomes poor. It is difficult to form a paste-like composition even when treated. 10.0
If the ratio exceeds 3, the crosslink density of the three-dimensional structure becomes too high, so that the silicone oil can be retained, and the paste composition does not become stable even when kneading with the silicone oil.

The low-viscosity silicone oil used in the paste composition may be either linear or branched. Examples thereof include methylpolysiloxane, methylphenylpolysiloxane, ethylpolysiloxane, ethylmethylpolysiloxane, and ethylmethylsiloxane. Examples thereof include phenylpolysiloxane and cyclic dimethylpolysiloxane such as octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane, and these may be used alone or as a mixture of two or more.

The above-mentioned crosslinked polyether-modified silicone is preferably blended in a water-in-oil type emulsified cosmetic in an amount of 0.1 to 10.0% by weight. If less than 0.1% by weight, 5
If 0.0% by weight or more of water cannot be emulsified, and if it exceeds 10.0% by weight, the spreadability is poor and the feeling of use is heavy, which is not preferable. When the crosslinked polyether-modified silicone is blended as a paste-like polyether-modified silicone composition, it is preferable that the blending amount of the crosslinked polyether-modified silicone is selected so as to be within the above range.

Next, the component (B) used in the present invention comprises a high molecular weight silicone represented by the above general formula (II) and / or an amino-modified or ammonium-modified high molecular weight silicone represented by the above general formula (III) It is.

In the present invention, the high molecular weight silicone (I
I) means that k in the above general formula is 3000 to 2000
A silicone having a molecular weight in the range of 0, preferably having a molecular weight of about 370,000 to 1.5 million, and has a soft rubber-like property at room temperature.

Specific examples of the high molecular weight silicone (II) include, for example, dimethylpolysiloxane, methylphenylpolysiloxane, dimethylpolysiloxane having a terminal hydroxyl group, and methylphenylpolysiloxane having a terminal hydroxyl group. Siloxane is preferred.

Commercially available high molecular weight silicone (II) includes, for example, X-21-7501G (manufactured by Shin-Etsu Chemical Co., Ltd.) and BY11-004 (manufactured by Dow Corning Toray Silicone Co., Ltd.). In the present invention, it is of course possible to use these commercially available products.

The amino-modified or ammonium-modified high-molecular-weight silicone represented by the above general formula (III) means that m and n in the above general formula are such that m + n = 3000 to 200
00 and in the range of n / m = 1 / 500~1 / 10000, an amino-modified or ammonium-modified high molecular weight silicone by R ^5.

In the amino-modified or ammonium-modified high molecular weight silicone (III), (m + n) is 3,000 to
20,000, preferably 4000 to 20,000
It is. If (m + n) is less than 3,000, the amino- or ammonium-modified high molecular weight silicone (III) becomes oily, and the protective effect on the skin and hair tends to be insufficient. Amino-modified or ammonium-modified high molecular weight silicone (III) becomes difficult to dissolve in other raw materials such as, for example, and there is a disadvantage in production.

Further, n / m is 1/500 to 1/100.
00, preferably 1/500 to 1/2000. If n / m exceeds 1/500, the content of amino groups or ammonium groups in the high-molecular-weight silicone will be too high. It is not preferable because side reactions occur and the odor of raw materials is more likely to accompany the product. On the other hand, n / m is 1/1000
If it is less than 0, the interaction of the amino-modified or ammonium-modified high molecular weight silicone (III) with the skin or hair may be insufficient, and there may be a tendency for the persistence of the skin and hair protection effect to be poor. Not preferred.

In the above formula (III), examples of the divalent hydrocarbon group having 3 to 6 carbon atoms represented by R ⁶ include:
Propylene group, tetramethylene group, pentamethylene group,
Hexamethylene group and the like. Examples of the alkyl group having 1 to 4 carbon atoms represented by R ⁷ and R ⁸ include, for example,
Examples include a methyl group, an ethyl group, a propyl group, an isopropyl group, and a butyl group. Examples of the halogen atom represented by A include a chlorine atom, a fluorine atom, an iodine atom, and a bromine atom.

The amino-modified or ammonium-modified high molecular weight silicone (III) can be produced by a conventional method. For example, it can be produced by subjecting γ-aminopropylmethyldiethoxysilane, cyclic dimethylpolysiloxane, and hexamethyldisiloxane to a polycondensation reaction under an alkali catalyst. Its properties are soft rubber-like, and by including it in the water-in-oil type emulsified cosmetic of the present invention, even if this cosmetic is used in a large amount or used continuously for a long time, the skin and hair will be sticky. In addition, it is possible to impart excellent gloss to the hair and a smooth feel to the skin and hair, and as a result, it is possible to improve the protective effect of the skin and hair.

As the high molecular weight silicone and / or the amino-modified or ammonium-modified high molecular weight silicone (III) of the component (B), any one or two or more kinds are selected and contained in the water-in-oil cosmetic of the present invention. However, it is more preferable to mix both the high molecular weight silicone and the ammonium-modified high molecular weight silicone.

When the high molecular weight silicone (II) and the amino-modified and ammonium-modified high molecular weight silicone (III) are combined and contained in the water-in-oil type cosmetic of the present invention, the stickiness of the cosmetic is reduced as much as possible. From the viewpoint that it is desirable to remove the weight of the feeling of use, the compounding ratio is high molecular weight silicone (II): amino-modified or ammonium-modified high molecular weight silicone (II
I) = 1: 9 to 9: 1 (weight ratio), preferably about 2: 8 to 8: 2. If the proportion of the amino-modified or ammonium-modified high-molecular-weight silicone (III) relative to the high-molecular-weight silicone (II) is too large, the cosmetic tends to be sticky and the feeling of use tends to be heavy. There is a tendency for the effect of imparting smoothness and protection effect on skin and hair by the preparation to be insufficient.

When the above-mentioned component (B) is contained in the water-in-oil type cosmetic of the present invention, it is preferable to dissolve it in a low-viscosity silicone oil or a low-viscosity hydrocarbon oil and blend it.
Examples of the low-viscosity silicone oil used for dissolving the component (B) include methylpolysiloxane (e.g., 6 mPas or 20 mPas), methylphenylpolysiloxane, ethylpolysiloxane, ethylmethylpolysiloxane, ethylphenylpolysiloxane, Further, cyclic dimethylpolysiloxanes such as octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane are exemplified.On the other hand, low-viscosity hydrocarbon oils include light liquid isoparaffin, isononyl isononanoate, isooctyl isononanoate, isononyl isomonyristate. And the like. These may be used alone or as a mixture of two or more.

The amount of component (B) is 0.1 to 10.0% by weight. Within this range, the amount of the water-in-oil type cosmetic is appropriately adjusted depending on the combination with the dosage form and other components. Preferably it is 0.5 to 5.0% by weight. If the amount is less than 0.1% by weight, it is difficult to obtain the expected effect. On the other hand, if the amount exceeds 10.0% by weight,
In terms of usability, it is not preferable because it causes weight and stickiness.

In the oil phase component used in the present invention, in addition to the components (A) and (B), oils used in ordinary emulsified compositions for cosmetics are used in a range which does not lack the uniformity of the oil phase. Can be blended. As such an oil, any of natural animal and vegetable oils and synthetic oils can be used. For example, liquid, pasty or solid hydrocarbons such as liquid paraffin and squalane, waxes, higher fatty acids, higher alcohols, esters, glycerides And silicone oils.

The oil phase component is blended in the water-in-oil emulsion cosmetic of the present invention in an amount of 10 to 50% by weight. If the amount is less than 10% by weight, it is difficult to make the cosmetic into a water-in-oil emulsion composition. If the amount exceeds 50.0% by weight, the water in the internal phase becomes too small, and the feeling of use is moist. Lack of feeling is not preferred.

The aqueous phase component (C) used in the present invention comprises:
It contains water or water as a main component, and contains various water-soluble components.
-90.0% by weight to obtain a water-in-oil type emulsified cosmetic having a high internal water phase. From the viewpoint of imparting a moist feeling, it is more preferable to add 60.0% by weight or more. Less than 50.0% by weight lacks moisture,
If it exceeds 90% by weight, it is difficult to obtain a water-in-oil emulsion composition.

[0039] In addition to the above essential components, the water-in-oil type emulsified cosmetic of the present invention has an aqueous component or an oil component commonly used in cosmetics, such as a humectant, a preservative and an antioxidant. , UV absorbers, beauty ingredients, fragrances, fragrances, thickeners,
Color pigments, glitter pigments, organic powders, hydrophobized pigments, tar pigments, and the like can be blended within a range that does not impair the effects of the present invention.

The high-inner-water-phase oil-in-water emulsified cosmetic composition of the present invention includes, for example, milky or creamy products such as emulsions, skin creams, hair creams, liquid foundations, eyeliners, mascaras, and eye shadows. And these products are manufactured by conventional methods.

[0041]

Next, the present invention will be described more specifically with reference to examples and comparative examples. The present invention is not limited by this. All amounts are by weight.
