Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD [0001] The present invention relates to an external composition for the skin. More specifically, the present invention is an invention relating to an external composition that can be smoothed by covering and smoothing irregularities and the like formed by various causes on the skin and visually, as if the irregularities and the like do not exist. is there.

[0002]

2. Description of the Related Art It goes without saying that one of the most important roles of makeup cosmetics is the "aesthetic role" that makes the appearance look beautiful. Specifically, this “aesthetic role” is usually performed by, for example, smoothing unevenness due to small pores in the skin or correcting the color of the skin.

[0003] However, it is also a fact that there are not a few irregularities on the skin which are difficult to correct even with the existing makeup cosmetics. For example, if the irregularities on the skin become so remarkable that they can be said to be "crater-like" due to acne, etc., keloid marks and skin marks due to burns,
It is difficult to correct surgical marks, deep wrinkles, deep scars, large pores and fine wrinkles with existing makeup cosmetics.

That is, among the makeup cosmetics, an oily solid cosmetic containing a powder component, an oil component and a wax, and an emulsified solid cosmetic containing a powder component, an oil component, a wax, water and a humectant are contained in these. Depending on the waxes
It fills in small irregularities such as irregularities due to small pores in the skin, but twists and sometimes falls off due to the movement of the skin, and it cannot correct the large irregularities on the skin as above. . In addition, in the existing makeup cosmetics, the coating color becomes opaque due to the difference in the refractive index of the blended components. As a result, the concave portions become opaque at the time of coating, and the convex portions have high transparency. Even if it is formed, the concave portion is visually conspicuous and is not practical.

Further, the above-mentioned large pores and fine wrinkles also
Forcibly correcting this with existing makeup cosmetics tends to result in an unnatural finish. Therefore, an external composition capable of smoothing large and small irregularities on the skin, particularly including irregularities that are difficult to correct with the conventional makeup cosmetics as described above, and making these irregularities visually inconspicuous. It is desired to provide.

[0006] The composition for external use to be provided, when correcting large irregularities on the skin as described above,
Even if it is applied thickly on the skin, it is necessary that it adheres to the skin without falling off, does not sag by gravity, and can be easily removed from the skin. Further, it is preferable that the transparency is high and the correction can be made so that the concave portion and the convex portion on the skin do not exist visually.

Further, when correcting the above-mentioned large pores and fine wrinkles, even if it is applied thickly on the skin, it adheres to the skin without falling off and gives a natural feeling, as if there are no pores and fine wrinkles. The correction can be performed as described above, and such a correction effect needs to be maintained for a long time (at least 2 hours or more).

As a means for solving this problem, the present inventors have already proposed a high-viscosity silicone oil having both proper adhesion to the skin and release properties, and a Newtonian fluid property of the silicone oil. In order to correct dripping on the skin based on the above, a composition for correcting unevenness having desired characteristics is provided by blending with a powder component (Japanese Patent Application No. 9-227387).

[0009]

The composition for correcting unevenness can be easily adhered to the skin without falling off even if it is applied thickly on the skin, and can be easily removed from the skin at the same time as it does not sag by gravity. In addition, the transparency was high, and it was possible to make corrections as if the irregularities did not exist, thereby satisfying some of the above-mentioned main objects. However, if it is applied for a long time after application on the skin, the part that has been in the texture will float and appear white, and after application, the skin will be broken apart, and the makeup will not stick over time (without texture) and The toughness was not enough.

[0010]

Means for Solving the Problems Accordingly, the present inventors have:
As a result of extensive studies as a specific problem, it has been intensively studied to provide an externally-applied composition capable of correcting unevenness and the like of the skin, which is excellent in long-lasting makeup stickiness (non-floating texture) and toughness. It has been found that the incorporation of the siliconized polysaccharide compound provides an external composition having desired properties.

That is, the present inventor has set forth in the present application an external composition containing a siliconized polysaccharide compound such as siliconized pullulan as a component for correcting irregularities on the skin (hereinafter, also referred to as the external composition of the present invention). provide.

The composition for external use of the present invention preferably contains a low-viscosity silicone oil and / or a powdery component. Examples of the powdery component include silicon dioxide powder, silicone resin powder, silicone rubber powder, and silicone resin-coated rubber powder. It is preferable to include at least a powder component having a refractive index of 1.3 to 1.5.

In the composition for external use of the present invention, various characteristics can be imparted by appropriately selecting the combination of the hardness and shape of the powder particles of the powder component to be blended (described later). Furthermore, in the composition for external use of the present invention, by applying a volatile component such as volatile silicone or water, the application thickness of the composition on the skin can be set to a specific thickness and used in various modes. It is possible (described later).

The composition for external use of the present invention is roughly classified into two types of external compositions. On the other hand, the external application composition of the present invention is an external application composition for correcting large unevenness on the skin as described above, and specifically, an external application composition mainly represented as “composition for unevenness”. (The composition for external use of the present invention in this embodiment is also referred to as the composition for correcting unevenness of the present invention).

In the composition for external use of the present invention, the compounding amount of the siliconized polysaccharide compound and the low-viscosity silicone oil in the composition for external use is based on the total weight of the composition for external use.
It is preferably 70.0% by weight or more based on the weight excluding the weight of the powder component (the weight of the powder component and the volatile component when the volatile component is blended in the external composition). 90.0% by weight or more of the entire powder component
It is preferable that the powder component has a refractive index of 1.3 to 1.5.

On the other hand, the composition for external use of the present invention is a composition for external use which is used as a general make-up cosmetic. However, large pores and fine wrinkles (the above-mentioned composition) which have conventionally been difficult to cover naturally. ) Can be covered while maintaining a natural feeling.
(The composition for external use of the present invention in this embodiment is also referred to as a composition for makeup of the present invention).

In the make-up composition of the present invention, the combined amount of the silicone-containing polysaccharide compound and the low-viscosity silicone oil in the external use composition is determined by subtracting the weight of the powder component and the volatile component from the total weight of the external use composition. 60.0% by weight or more based on the weight of the powder component, and 20.0% by weight or more of the total
It is preferable that the powder component has a refractive index of 1.3 to 1.5.

The mode of blending the low-viscosity silicone oil in the composition for external use of the present invention differs depending on whether the composition for external use of the present invention is a "composition for correcting unevenness" or a "composition for makeup". This will be described later.

Of these powder components, all or some of them have a refractive index (in the present invention, a refractive index calculated according to Snell's law) of approximately 1.3 to 1.5.
It is preferable to mix in the composition for external use of the present invention as a powder component which is as follows. That is, the refractive index in this range substantially overlaps with the refractive indices of the above-mentioned silicone-containing polysaccharide compound and low-viscosity silicone oil which are other compounding components, and the powder component having the refractive index in this range is combined with the composition for external use of the present invention. The composition for external use of the present invention which does not impair the transparency of the silicone-containing polysaccharide compound and the low-viscosity silicone oil within a desired range is provided.

Specifically, examples of the powder component having a refractive index in this range include silicon dioxide powder, silicone resin powder, silicone rubber powder, and silicone resin-coated rubber powder.

The silicon dioxide powder is commercially available as a so-called silica powder [for example, Chemiselen (manufactured by Sumitomo Chemical Co., Ltd.), spherical silica P-1500 (manufactured by Kasei Kagaku Co., Ltd.), Aerosil 200 (manufactured by Deggusa). ,
Aerosil R972, Sildex L-51 (manufactured by Asahi Glass Co., Ltd.) and the like, and in the composition for external use of the present invention, these commercially available products can be used. By incorporating this silicon dioxide powder into the composition for external use of the present invention, the adhesion of the composition for external use of the present invention to the skin can also be improved.

The silicone resin powder is obtained by pulverizing a silicone resin obtained by copolymerizing a polyfunctional siloxane component, and a wide variety of silicone resin powders are commercially available. Such commercially available products include, for example, a Tospearl series (Tospearl 145) manufactured by Toshiba Silicone.
A). Since these silicone resin powders have a refractive index substantially equal to that of the siliconized polysaccharide compound and low-viscosity silicone oil, the system when mixed with these can be kept transparent.

The silicone rubber powder includes an organopolysiloxane elastomer composition or an organopolysiloxane powder obtained from an organopolysiloxane resin composition,
For example, an organopolysiloxane cured product powder having a particle diameter of 100 microns or less (Japanese Patent Publication No. 17162/1992) is exemplified, and various silicone rubber powders are commercially available. Examples of such commercially available products include Toray Dow Corning Silicone Trefill Series (Trefill E506W, Trefill E505C, Trefill E506C, Trefill E505W, etc.).
Can be mentioned. In particular, these silicone rubber powders have a higher elasticity than other powder components, and by blending them in the composition for external use of the present invention, the elasticity of the composition for external use of the present invention approximates the elasticity of the skin. To get closer to the real skin condition.

The silicone resin-coated rubber powder is obtained by coating spherical particles of silicone rubber with a polyorganosilsesquioxane resin (Japanese Patent Application Laid-Open No. 7-196815). -52-113
9K and the like. By blending the silicone resin-coated rubber powder in the composition for external use of the present invention, the ease of application of the composition for external use of the present invention on the skin can be improved.

The specific types and combinations of the above-mentioned powder components that can be incorporated into the composition for external use of the present invention can be appropriately selected as necessary. For example, as at least a part of the powder component, the hardness of the powder particles is determined by the average rubber hardness [in the present invention, the “average rubber hardness” refers to the hardness test method for vulcanized rubber and thermoplastic rubber (JIS K6253)
Means a durometer hardness test type A (medium hardness test) score), but a rubber powder component of less than 50 (typical examples of the rubber powder component include the silicone rubber powder and the silicone resin-coated rubber powder described above). Can be given) and blended in the composition for external use of the present invention, whereby flexibility can be imparted to the composition for external use of the present invention. As the rubber powder component, the hardness of the powder particles is selected only from those having an average rubber hardness of 50 or more, and when blended with the composition for external use of the present invention, the resulting composition becomes too hard and is difficult to spread on the skin, which is preferable. Absent.

Further, in the composition for external use of the present invention, as the powder components, a rubber powder component having a powder particle hardness of less than 50 and an other powder component, specifically, for example, an average rubber hardness By incorporating both of a rubber powder component of 50 or more and an inorganic powder such as a silicon dioxide powder in combination, it is possible to obtain the composition for external use of the present invention, which has a good cosmetic stickiness over time (non-floating texture). .

The shape of the particles of the powder component is mainly spherical, plate-like, amorphous, or the like, but powder components having two or more different particle shapes, for example, a powder component having a spherical particle shape ( For example, a rubber powder component) and an amorphous powder component (for example, an inorganic powder component such as silicon dioxide powder of amorphous powder particles) are preferably combined with the composition for external use of the present invention.

When two or more kinds of powder components having different particle shapes as described above, in particular, a rubber powder component in which the powder particles have a spherical average rubber hardness of less than 50 and an inorganic powder component of the amorphous powder particles are combined and compounded, It is preferable because it makes it possible to improve the long-lasting makeup (non-texture) of the composition for external use of the invention.

By including the powder component of the amorphous powder particles as the powder component, it is possible to improve the thixotropic property of the composition for external use of the present invention and to improve the stability over time of the composition. It is. In other words, the application thickness of the composition for external use of the present invention on the skin is actively adjusted (particularly, the case where the composition for external use of the present invention is a “composition for makeup”). If it is necessary to further improve the stability over time, by including the powder component of the amorphous powder particles as a powder component,
You can do this.

Further, in the composition for external use of the present invention, when powder components having different particle shapes are combined and blended, a powder component having a spherical particle shape, particularly a rubber powder component having a spherical particle shape, and a powder component having a particle shape other than a spherical shape are used. For example, the mixing ratio of the plate-like or amorphous powder component can be appropriately selected according to the specific form and purpose of the composition for external use of the present invention, and is not particularly limited.

That is, it is possible that most of the whole powder component to be blended in the composition for external use of the present invention is a powder component which is a powder particle of any shape (including an amorphous shape). It is also possible to mix them in a quantitative ratio.

For example, when a powder component having an amorphous particle shape is blended with a powder component having another particle shape in the composition for external use of the present invention, the powder component having an amorphous particle shape is generally blended. It is possible to select a compounding ratio in a very wide range of about 10 to 90% by weight of the entire powder component (the range of the numerical value of the compounding ratio is only a guideline).

The amount of the powder component having an amorphous particle shape is
If the amount is relatively too small (in the above example, less than about 10% by weight of the entire powder component), when the composition for external use of the present invention is a composition for correcting unevenness, the makeup lasts for a long time (without texture lifting). ), When the composition for external use of the present invention is a makeup composition, it is difficult to sufficiently exhibit the effect of correcting large pores and fine wrinkles. Conversely, if the compounding amount of the powder component having an amorphous particle shape is relatively too large (in the above example, about 90% by weight of the entire powder component), the composition for external use of the present invention may contain: `` Composition for unevenness correction ''
In the case of lacking the flexibility and toughness of the resulting composition, when applied to the skin, by the movement of the skin, it is easy to separate, the external composition of the present invention, `` makeup composition '', There is a strong tendency that the stability over time of the composition deteriorates.

In the composition for external use of the present invention, coloring may be positively performed depending on the mode. In such a case, a coloring agent or a pigment can be blended in the composition for external use of the present invention.

As the coloring agent and the pigment, those which are generally known can be used. For example, inorganic white pigments such as titanium dioxide and zinc oxide; inorganic red pigments such as iron oxide (iron oxide) and iron titanate; Inorganic brown pigments such as γ-iron oxide; inorganic yellow pigments such as yellow iron oxide and loess; inorganic black pigments such as black iron oxide, carbon black and lower titanium oxide;

No. 1, Red 202, Red 204, Red 205, Red 220, Red 226, Red 228, Red 405
Organic pigments such as No. 203, Orange No. 203, Orange No. 204, Yellow No. 205, Yellow No. 401 and Blue No. 404; Red No. 104, Red No. 106, Red No. 227, Red No. 230
No., Red No. 401, Red No. 505, Orange No. 205, Yellow No. 4, Yellow No. 5, Yellow No. 202, Yellow No. 203, Green No. 3
No. 1, Blue No. 1 and the like, and organic pigments such as zirconium, barium and aluminum lake.

Of these coloring agents and pigments, the coloring agents and pigments present as powder particles after being incorporated into the composition for external use of the present invention shall be treated as “powder components” in the present invention.

The compounding amount of the entire powder component in the composition for external use of the present invention depends on the type and specific surface area of the powder component to be compounded (the larger the specific surface area of the powder component to be compounded, the smaller the preferable compounding amount of the powder component) ) And the like are not particularly limited, but are preferably about 5.0 to 80.0% by weight of the whole composition.
When the amount is less than 5.0% by weight of the whole composition,
When the composition for external use of the present invention is used on the skin, there is a strong tendency that sagging is not sufficiently suppressed. When the composition exceeds 80.0% by weight, the properties of the composition for external use of the present invention are maintained in a paste form. The tendency to make things even more difficult.

The composition of the powder component having a refractive index of about 1.3 to 1.5 in the composition for external use of the present invention is as follows.
The composition for external use of the present invention also differs depending on whether it is a "composition for unevenness correction" or a "composition for makeup". This will be described later.

As such volatile components, it is possible to select volatile components commonly used in external compositions such as cosmetics, and specifically, for example, volatile silicone oil, water, lower alcohols and the like (such as Mixtures are also possible). These volatile components may be contained in a specific embodiment of the composition for external use of the present invention (for example, “composition for unevenness correction” or “composition for makeup” described below) or a dosage form (for example, oil-based or emulsified-based). Etc.) can be appropriately selected. By blending these volatile components,

Specific Embodiment of External Composition of the Present Invention As described above, the external composition of the present invention mainly has an embodiment as a "composition for unevenness correction" and an "composition for makeup". Hereinafter, each of the representative embodiments will be described.

(1) When the composition for external use of the present invention is a “composition for unevenness correction”: The “composition for unevenness correction” is such that the unevenness on the skin is so remarkable that it can be said to be “crater-like” due to acne or the like. A topical composition whose main purpose is to actively correct relatively large irregularities on the skin, such as those that have become damaged, keloid scars and skin graft scars due to burns, surgical scars, deep wrinkles, deep scars, etc. .

In order to achieve this purpose effectively, a relatively thick coating is applied on the skin (applied layer having a thickness of about 1 to 3 mm).
It is usually required to have properties that can be used and properties such as excellent transparency.

The following factors are taken into account in the composition for correcting unevenness of the present invention in order to make it possible to preferably perform the “thick application” and the “maintaining transparency”. be able to.

That is, the amount of the low-viscosity silicone oil in the composition for external use of the present invention is not particularly limited. However, in the composition for correcting unevenness of the present invention, 25% in combination with the siliconized polysaccharide compound. 1mPa ・ ℃
s to 15,000,000 mPa · s, preferably 1 mPa · s
１００1,000,000 mPa · s, particularly preferably 1 mPa · s〜
By blending a low-viscosity silicone oil in a viscosity range of 100,000 mPa · s, it is possible to apply the composition for external use of the present invention thickly on the skin, It is possible to improve the ease of application on the skin. [In the present invention, the term “viscosity” refers to a rotor No. 1 using a Shibaura Bismetron manufactured by Shibaura System Co., Ltd. unless otherwise specified. 7 and the number of rotations is 0.
The viscosity is measured at 5 rpm (measured at 25 ° C.
Performed in a constant temperature bath).

In this case, the combined amount of the siliconized polysaccharide compound and the silicone oil in the composition for correcting unevenness of the present invention is determined based on the weight of the powder component described later (the volatile component is added to the external composition). 70% by weight, excluding powder components and volatile components).
It is preferably at least 0% by weight. In this case, the transparency of the obtained composition is extremely high, so that the composition can be more uniformly coated so that the unevenness does not exist visually, regardless of the size of the unevenness on the skin or the depth thereof.
