Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention belongs to the technical field related to a water-in-oil emulsion composition. More specifically, it provides a refreshing feeling upon application, has good cosmetic durability, has excellent emulsification stability, and has a wide range of viscosity and hardness from low viscosity to high viscosity, or from hard cream to gel. It is an invention belonging to the technical field related to a water-in-oil emulsion composition applicable to a mold.

[0002]

2. Description of the Related Art When emulsified cosmetics whose components are emulsified are classified by emulsifying system, they can be classified into oil-in-water emulsified cosmetics and water-in-oil emulsified cosmetics. Emulsified cosmetics, when compared to oil-based cosmetics that do not contain water at all, have a refreshing feeling of use when applied to the skin because they contain water in their ingredients, and suppress the oily feeling due to the oil content It has the advantage of being done. In addition, the dosage form is often in the form of a liquid or cream, and has excellent features such as good spreadability on the skin and easy to obtain a uniform finish without unevenness.

[0003] In particular, water-in-oil type emulsified cosmetics have a higher microbial resistance since the oil phase is a continuous layer than oil-in-water type emulsified cosmetics, and leave an oil film with low moisture permeability on the skin even when used. It is possible to protect the skin from drying out for a long time. In addition, when a water-in-oil type cosmetic is used, the components on the skin are less likely to re-emulsify even if they come into contact with water by water bathing, water work, sweating, etc. There are also advantages such as difficulty in breaking. However, in the conventional water-in-oil type emulsified cosmetic, it is difficult to obtain a stable emulsified state, and in order to achieve stabilization, the amount of water contained in the dispersed phase is limited, In many cases, a high oil component is used, and when used in practice, there is a drawback that a sticky feeling of use and a feeling of oiliness are strong.

[0004] In order to solve this drawback, a specific polyether-modified silicone is used as an emulsifier, and an aqueous phase containing a certain concentration of lower alcohol is added to an oil phase containing a specific polysiloxane and a water-repellent powder. By doing so, to form a water-in-oil emulsion, the aqueous phase is emulsified for a long time,
There is disclosed a technique for providing a water-in-oil type emulsified cosmetic which has a refreshing sensation at the time of application and does not easily lose its makeup after application and has excellent emulsion stability (Japanese Patent Publication No. 5-32363).

[0005]

However, even in the emulsified cosmetic obtained by this technique, the range of viscosity and hardness that can be prepared is limited due to the limited molecular weight of the polyether-modified silicone. There is a problem that the dosage form applicable above is limited to a liquid or cream having a narrow viscosity range and hardness range. In particular, in recent years, cosmetics of various dosage forms have been demanded in the market, and it is necessary that water-in-oil type emulsified cosmetics satisfy this demand.

Therefore, the problem to be solved by the present invention is that the aqueous phase is emulsified for a long time, has a refreshing sensation at the time of application, and is not only excellent in emulsification stability that does not easily lose its makeup after application, but also has a wider variety of dosage forms. It is an object of the present invention to provide a water-in-oil type emulsified composition which can be applied to water.

[0007]

Means for Solving the Problems The present inventor has made intensive studies to solve this problem. As a result, by using two kinds of specific polyether-modified silicones as an emulsifier, a refreshing feeling can be given at the time of application, the makeup lasts well, the emulsion stability is excellent, and the viscosity is low to high or hard. From cream to gel

Embodiments of the present invention will be described below. The polyether-modified silicone which is the component (a) blended in the water-in-oil emulsion composition of the present invention (hereinafter, referred to as the present composition) has a polyoxyalkylene group represented by the general formula (1). It is an organopolysiloxane. In this polyether-modified silicone (1), the alkyl group having 1 or more and 5 or less carbon atoms that can be taken by R or R ′ is not particularly limited. For example, a methyl group, an ethyl group, an isopropyl group,

The amount of the polyether-modified silicone (1) in the composition of the present invention is appropriately selected in accordance with the viscosity and hardness intended in the composition of the present invention, in relation to the polyether-modified silicone (2) described later. However, it is generally in the range of 0.1% by weight or more and 10.0% by weight or less, preferably 1.5% by weight or more and 7.0% by weight or less of the whole composition. If the amount is less than 0.1% by weight of the whole composition, the emulsification stability is poor, which is not preferable. If the amount is more than 10.0% by weight, the spread of the composition on the skin becomes heavy and the sticky feeling is used. And it is not preferable. The polyether-modified silicone (1) can be produced by a generally known method depending on the specific structure, and a commercially available product can also be used.

The polyether-modified silicone which is the component (b) to be blended in the composition of the present invention is an organopolysiloxane having a polyoxyalkylene group represented by the general formula (2). In the polyether-modified silicone (2), the alkyl group having 1 to 5 carbon atoms that can be taken by R ″ or R ′ ″ is not particularly limited.
For example, methyl, ethyl, isopropyl, n-propyl, tert -butyl, n-butyl, sec -propyl, n-pentyl, isopentyl, neopentyl, tert -pentyl and the like can be mentioned. it can. In addition,
R ″ and R ′ ″ may be the same or different, and R ″ may be the same or different. And the like.

R ″ is preferably a hydrogen atom or a methyl group, and R ″ ′ is preferably a hydrogen atom rather than the above-mentioned alkyl group. Further, among the integers a ′, b ′, c ′, m ′ and n ′ representing the number of bonds, a ′ is 1

Or less, preferably 20 or more and 30 or less, and n ′ is 1 or more and 5 or less, preferably 2 or more and 5 or less.

The amount of the polyether-modified silicone (2) in the composition of the present invention is appropriately selected in relation to the above-mentioned polyether-modified silicone (1) according to the viscosity and hardness intended in the composition of the present invention. However, it is generally in the range of 0.001% by weight or more and 10.0% by weight or less, preferably 0.5% by weight or more and 5.0% by weight or less of the whole composition. If the amount is less than 0.01% by weight of the whole composition, the emulsion stability is poor, which is not preferable. If the amount exceeds 10.0% by weight, the oily feeling tends to be excessive, which is not preferable. The polyether-modified silicone (2) can be produced by a generally known method according to the specific structure, and a commercially available product can also be used.

As described above, when the polyether-modified silicone (1) as the component (A) and the polyether-modified silicone (2) as the component (B) are combined and blended in the composition of the present invention, the composition becomes extremely A wide range of viscosity (specifically, from about 1000 cps to about 50,000) and hardness (specifically, 1 to
It is possible to produce a water-in-oil emulsion composition (up to around 30) in combination with the components described below, and to apply the composition of the present invention to a very wide range of dosage forms from gels to hard creams. Is possible. This is a marked difference from the above-mentioned conventional technology (Japanese Patent Publication No. 5-32363) in which the emulsified composition is a liquid or cream composition having a limited viscosity region and hardness region.

In the composition of the present invention, if the ratio of the polyether-modified silicone (1) is larger than (2), the composition of the present invention is in the form of a hard cream or gel. Or cream.

The component (c) is composed of at least 60.0% by weight of the polysiloxane represented by the general formulas (3), (4) and / or (5), and less than 40.0% by weight of the polysiloxane. It consists of other oil components. Each of these three types of polysiloxanes is characterized by being able to impart a refreshing feeling to use to the composition of the present invention by its combination. Any of these three types of polysiloxanes can be used alone in the composition of the present invention, but they can also be used in combination as appropriate.

Among these polysiloxanes, the polysiloxane (5) is particularly volatile, and when the composition of the present invention containing the same is actually used as an emulsified cosmetic, the polysiloxane is Since it does not remain on the skin, it has almost no oily feeling during use, and a particularly fresh feeling can be imparted to this emulsified cosmetic. Furthermore, this polysiloxane (5) is different from other polysiloxane (3).
And (4), it is superior in long-term stability over time.

Therefore, among these polysiloxanes,
It is preferable that at least this polysiloxane (5) is incorporated into the composition of the present invention alone or in combination with another polysiloxane. These three types of polysiloxanes
Both can be produced by a generally known method,
Further, commercially available products can be easily obtained. Commercially available products include, for example, SH244, manufactured by Toray Silicone Co., Ltd.
SH344, SH245, DC345, etc .; KF994, KF995, KF996, KF99 manufactured by Shin-Etsu Chemical Co., Ltd.
56 etc .; TSF404, TSF4 manufactured by Toshiba Silicone Co., Ltd.
05, TSF406 and the like.

In the component (C), oil components other than the above-mentioned three kinds of polysiloxanes include hydrocarbon oils such as liquid paraffin and squalane; natural animal and vegetable oils such as olive oil and jojoba oil; octyldodecyl myristate; , IP
Synthetic ester oils such as P (isopropyl palmitate) and IMP (isopropyl myristate); higher alcohols such as stearyl alcohol and batyl alcohol; and waxes such as ceresin, microcrystalline wax, candelilla wax, carnauba wax and the like.

When the amount of the polysiloxane in the component (c) is less than 60.0% by weight, the emulsified particles tend to become coarse when emulsified, and the long-term stability is maintained. It is difficult.

The amount of the component (c) in the composition of the present invention is from 7.0% by weight to 60.0% by weight, preferably from 15.0% by weight to 40.0% by weight, based on the whole composition.
It is blended in the range of not more than% by weight. If the amount of the component (c) is less than 7.0% by weight of the whole composition, the emulsifying system tends to be unstable when emulsifying. If the amount exceeds 60% by weight, the aqueous phase The use of the emulsified composition due to the presence of the compound becomes poor in refreshing feeling and refreshing feeling, which is not preferable.

Further, the component (d) of the surface water-repellent powder is as follows:
It is a known powder that has been subjected to a surface water-repellent treatment. Examples of the surface-repellent powder include surface pigments such as talc, sericite, mica, kaolin, silica, nylon powder, polyethylene powder, silk powder, and cellulose powder; titanium oxide, iron oxide, zinc oxide, and ultramarine. , Blue, chromium oxide, organic tar dyes, lakes, and the like; or composite pigments such as titanium mica, iron oxide coated mica, and the like.
Examples thereof include silicone, higher fatty acids, higher alcohols, fatty acid esters, metal soaps, amino acids, alkyl phosphoethers, and fluorine compounds. In addition, the surface water repellent treatment step using these surface water repellents,
A well-known water-repellent treatment step commonly used for ordinary powders can be appropriately employed.

The preferred surface water-repellent powder of the component (d) is, for example, a powder subjected to a surface water-repellent treatment using a surface water-repellent such as a higher fatty acid, a dextrin fatty acid ester, a fluorine compound, or silicone. Body. The powder obtained in this way has a strong water repellency, and even when actually applied to the composition of the present invention, it is resistant to water and sweat, and is less likely to lose makeup. Further, when emulsified, the emulsified particles are dense and have excellent long-term stability over time.

In the case of an emulsified composition according to the composition of the composition of the present invention in which untreated powder that has not been subjected to a surface water repellent treatment, a relatively stable emulsified composition can be obtained.
Due to the strong hydrophilicity of the untreated powder, makeup loss due to water or sweat is very likely.

The amount of the component (d) in the composition of the present invention is 3.0% by weight or more and 60.0% by weight or less, preferably 7.0% by weight or more and 30.0% by weight or less of the whole composition. % By weight or less. The compounding amount is 3.0 of the whole composition.
When the amount is less than 10% by weight, the color of the composition becomes poor, which is not preferable as a makeup cosmetic. Conversely, if it is added in an amount exceeding 60% by weight of the entire composition,
The emulsified composition tends to become extremely powdery, and the refreshing feeling tends to be poor.

The lower alcohol used as the component (e) in the composition of the present invention is not particularly limited, and generally available lower alcohols such as methanol, ethanol, propanol, isopropanol, isobutyl alcohol and tert- alcohol -Butyl alcohol and the like.

By blending the component (e) in the composition of the present invention, a refreshing sensation can be imparted to the composition when used. The amount of the component (e) in the composition of the present invention is 0.1% by weight or more of the total composition;
0% by weight or less, preferably 3.0% by weight or more;
It is blended at a ratio of 0% by weight or less. If the amount is less than 0.1% by weight of the whole composition, it is difficult to sufficiently impart a refreshing sensation during use to the composition, which is not preferable. Then, the base odor becomes remarkable, which is not preferable.

Further, water as the component (f) to be incorporated in the composition of the present invention is 0.1% by weight or more of the whole composition of the present invention.
70.0% by weight or less, preferably 5.0% by weight or more,
It is blended at a ratio of 40.0% by weight or less.

The components listed above are not limited to the components that can be added to the composition of the present invention. In addition to the above-mentioned components being used alone in the composition of the present invention, two or more kinds of the above-mentioned components can be appropriately combined and used according to the purpose.

The composition of the present invention can be prepared, for example, as follows. First, component (c) and component (a)
(B) is added and stirred. Next, the components (a) and (b)
After dispersing, the component (d) is added, and the mixture of the components (e) and (f) is added little by little with further stirring, and the mixture is further stirred to obtain the desired composition of the present invention (water-in-oil emulsion composition). Thing). In the above-mentioned production process, the temperature can be selected from any temperature from 5 to 90 ° C., and in any case, a stable water-in-oil emulsion composition can be obtained.

The characteristic of the composition of the present invention thus obtained is that when the powder is present inside the emulsified particles, it tends to have poor long-term emulsification stability. That is, a state in which the powder is adsorbed on the surface of the particles of the aqueous phase of about 50 μm is observed. Another characteristic of the emulsified particles is that they are very stable when left standing or shaken, but are easily broken when the solution is made into a thin film and given a light shear. This indicates that the same phenomenon occurs when actually applied to the skin.Thus, while the composition of the present invention is a water-in-oil type emulsion composition, the emulsified particles are immediately formed upon application. It is thought that the water phase containing lower alcohol comes into direct contact with the skin, which causes a refreshing feeling.

The composition of the present invention has a high viscosity and hardness when compared with conventional emulsion compositions based on the same system, even in a very wide range of viscosity and hardness. Even when the composition of the present invention is applied to a mold, the above-mentioned refreshing feeling can be maintained.

The composition of the present invention is applied to cosmetics and the like on the premise of formation of a water-in-oil type emulsion containing powder, especially makeup cosmetics such as foundations and lipsticks. It is suitable for use in foundations, as it can clearly perceive the refreshing sensation and the difficulty of breaking makeup, which are characteristic features.

As described above, the composition of the present invention can be used in a wide range of viscosity and hardness. The intended effect of the present invention can be equally exerted on foundations of high viscosity and high hardness such as types. The specific formulation of the composition of the present invention will be described in Examples described later.
