[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-phase type UV protection cosmetic composition. More specifically, the present invention relates to a UV protection cosmetic composition which continuously exhibits an excellent UV protection effect and has a good feeling of use when it is aqueous.

[0002]

2. Description of the Related Art Ultraviolet rays cause sunburn on the skin and further accelerate aging of the skin. Therefore, in order to protect the skin from ultraviolet rays, conventionally, ultraviolet protection cosmetics have been used in which an inorganic ultraviolet scattering agent such as titanium dioxide or zinc oxide, an ethyl urocanate, or an ultraviolet absorber such as aminobenzoate is blended. There is.

Further, as a UV protective cosmetic, it has a UV protective effect by encapsulating a UV protective agent in a porous resin in order to enhance safety in use and not to impair the makeup effect. Makeup cosmetics have been proposed (Claims of Japanese Patent Publication No. 62-51931). Further, as a UV protection cosmetic composition with improved safety in use, a foam-shaped product in which a UV absorber is encapsulated in microcapsules such as titanium dioxide has also been proposed (JP-A-6-116129). The scope of the claims).

[0004]

However, all of the conventional UV-protective cosmetics are emulsions such as creams and emulsions that use a large amount of emulsifier, and thus have a sticky feeling due to the emulsifier, and are suitable for use. I can't get the feeling. In addition, since the UV protection cosmetics once applied to the skin easily flow off due to sweat etc. due to the emulsifier,
It also lacks the durability of UV protection.
Further, there is a problem that the emulsifier irritates the skin and causes rough skin. For this reason, a new type of UV protection cosmetic composition that does not contain an emulsifier, or contains a small amount of it, and can continuously exert the UV protection effect has been desired.

The present invention is intended to solve the problems of the prior art as described above, and provides a UV protection cosmetic composition having an excellent feeling of use and capable of continuously exerting the UV protection effect. The purpose is to do.

[0006]

DISCLOSURE OF THE INVENTION The present inventors have examined the effects of UV protection, their durability and safety in use in combination with various UV protection agents and their media. It was found that the above object can be achieved by using an aqueous medium without using it, and supporting and dispersing an oily ultraviolet absorber on the oil-absorbing powder therein, and completed the present invention.

[0007] That is, the present invention provides a two-phase type ultraviolet protective cosmetics which comprises (A) an oil-based ultraviolet absorber, (B) an oil-absorbent powder and (C) an aqueous medium. In particular, (A) an oil-based ultraviolet absorber is (B) as a preferred embodiment in which a good feeling of use and a long-lasting UV protection effect can be obtained.
Provided is a two-phase type ultraviolet protective cosmetic material, which is carried on an oil-absorbing powder and is dispersed in (C) an aqueous medium.

Further, the present invention provides a method for producing such an ultraviolet protective cosmetic composition by mixing (A) an oil-based ultraviolet absorber and (B) an oil-absorbing powder to obtain an (A) oil-based ultraviolet absorber ( (B) An oil-absorbing powder is carried on an oil-absorbing powder, and then the oil-absorbing powder carrying an oily ultraviolet absorber is mixed with (C) an aqueous medium.

The present invention will be described in detail below.

The cosmetic composition of the present invention can be used as an ultraviolet protective agent.
An oil-based UV absorber (component (A)) is used. This allows the oil-absorbent powder (component (B)) to favorably carry the ultraviolet absorber.

As such oily ultraviolet absorbers, known aminobenzoate-based, salicylate-based, cinnamate-based, benzophenone-based, urocanic acid-based ultraviolet absorbers and vitamins can be used. More specifically, as the aminobenzoate ultraviolet absorber,
2-ethylhexyl-p-dimethylaminobenzoate, amyl-p-dimethylaminobenzoate, glyceryl-p-aminobenzoate, ethyl-p-dimethylaminobenzoate, ethyl-p-diethylaminobenzoate, glyceryl-mono-p-aminobenzoate, etc. As the salicylate-based ultraviolet absorber, pt-butyl salicylate, p-octylphenyl salicylate, dipropylene glycol salicylate or the like can be used, and a cinnamate-based ultraviolet absorber can be used. Examples include 2-ethoxyethyl-p-methoxycinnamate and 2,2'-bis (p-methoxystyryl)
-Ethyl-p-methoxycinnamate, methyl-2,5
-Diisopropyl cinnamate or the like can be used, and as the benzophenone-based UV absorber, 2-hydroxy-4-methoxybenzophenone, 2-hydroxy-4-methoxy-4'-methylbenzophenone, 2-hydroxy-4-methoxy. -5-sulfobenzophenone,
Sodium 2,2'-dihydroxy-4,4'-dimethoxy-5-sulfobenzophenone, 2,2 ', 4,4'-
Tetrahydroxybenzophenone, 2,4-dihydroxybenzophenone, 2-hydroxy-4-methoxybenzophenone, 2,2'-dihydroxy-4,4'-dimethoxybenzophenone and the like can be used. As the vitamins, vitamin A ₁ , vitamin A ₂ , vitamin A ₃ , vitamin B ₂ , vitamin B _{12 and the} like can be used.

If the amount of the oil-based UV absorber used is too small, the UV protection effect cannot be obtained, and if it is too large, the effect is saturated. Therefore, it is usually 0.1 to 10% by weight of the UV protection cosmetic composition.
It is preferable that

On the other hand, the component (B) used in the present invention
The oil-absorptive powder of (1) carries the oil-based UV absorber of the above-mentioned component (A), whereby the oil-based UV absorber can be well dispersed in an aqueous medium by using no emulsifier or using it in a small amount. It is what makes me.

As such an oil-absorbing powder, those having an average particle size of 0.005 to 30 μm are preferable, and particularly 0.0
The average particle size is preferably 1 to 30 μm, and more preferably 0.1 to 30 μm. When the average particle diameter is less than 0.005 μm, the skin feels squeaky during use and the usability deteriorates. On the contrary, when the average particle size exceeds 30 μm, the surface area per unit weight of the oil-absorbing powder becomes too small and the oil-absorbing speed decreases.
Also, the adhesion to the skin is reduced. In addition, the value of the average particle diameter here is an electron probe microanalyzer (for example,
JXA-840A, manufactured by JEOL Ltd.).

Further, as the oil-absorbing powder, JIS K
5101 (1978) has an oil absorption capacity of 0.5 ml squalene / g measured according to the oil absorption measuring method.
The above is preferable, and 1 ml squalene / g or more is particularly preferable. Oil absorption capacity is 0.5 ml squalene / g
When it is less than the above range, it becomes difficult to sufficiently carry the oily ultraviolet absorber, and it becomes difficult to achieve the effect of the present invention.

JIS K 5101 (1978)
According to the report, boiled linseed oil is used as the oil, but the above oil absorption capacity is defined by using squalene, which is similar to sebum. That is, 1 g of the oil-absorbing substance was placed on a glass plate and kneaded with a spatula while dropping squalene little by little, and the end point was the point when the whole oil-absorbing substance became a paste, and per 1 g of the oil-absorbing substance at that time The amount of squalene (ml) is used as the oil absorption amount.

As the oil-absorbing powder having the above characteristics, for example, JP-A-63-316715 and JP-A-63-316715.
It can be appropriately selected and used from among those described in detail in JP-A-316716, and more specifically, for example, use of powders composed of substances shown in (i) to (iii) below. You can

(I) Natural Organic Polymer Examples of the natural organic polymer include pulp and the like.

(Ii) Synthetic Organic Polymer As the synthetic organic polymer, silicone, nylon, polyethylene, polypropylene, polystyrene, urea resin, porous vinyl-based polymer, divinylbenzene or polyfunctional cross-linking with the monomer constituting these polymers is used. Examples thereof include copolymers with agents. These polymers may be subjected to various chemical or physical treatments in order to improve surface properties, internal structure, pore size, pore porosity, particle size and the like.

(Iii) Complex of Natural or Synthetic Organic Polymer with Inorganic Compound As such a substance, the natural organic polymer of (i) or
The surface of the porous material composed of the synthetic organic polymer of (ii) is S
Examples thereof include those coated with an inorganic compound such as iO ₂ , TiO ₂ , ZnO ₂ , kaolin, talc, mica, sericite, and montmorillonite, and conversely those coated with an organic polymer on the surface of an inorganic carrier.

Among such oil-absorbing powders, the oil-absorbing ability,
From the viewpoints of feel, adhesion to the skin, etc., it is particularly preferable to use a porous vinyl polymer obtained by polymerizing and porosifying at least one vinyl monomer having a solubility parameter of 7 to 10. it can. When the solubility parameter of the vinyl-based monomer is out of the range of 7 to 10, the compatibility between the porous vinyl-based polymer obtained from the monomer and the oil-based ultraviolet absorber is decreased, and the amount of the oil-based ultraviolet absorber carried is reduced. It tends to be insufficient.

Examples of the vinyl monomer having a solubility parameter of 7 to 10 include esters of methacrylic acid or acrylic acid with higher alcohols having 8 to 24 carbon atoms, unsubstituted or linear or branched alkyl groups having 1 to 12 carbon atoms. Substituted styrene derivative, vinyl ester of saturated carboxylic acid having 8 to 20 carbon atoms, acrylic acid, methacrylic acid, 4 to 4 carbon atoms
The diolefin of 6 and the like can be preferably exemplified. Of these, esters of higher alcohols having 8 to 24 carbon atoms and acrylic acid or methacrylic acid are preferable from the viewpoint of compatibility with the oily ultraviolet absorber. This ester may be polymerized alone, but it is preferable to copolymerize it with styrene or an alkyl-substituted styrene having a glass transition temperature of 100 ° C. or higher in order to increase the porosity and improve the oil absorption ability. In this case, the weight ratio of ester / styrene is preferably 30/70 or more. When this ratio is small, the obtained porous vinyl-based polymer becomes too hard, and the feeling of use when blended in an ultraviolet protective cosmetic composition is deteriorated.

Further, the porous vinyl polymer preferably has a three-dimensional crosslinked structure so as not to be dissolved in the oily ultraviolet absorber, and therefore as a crosslinking agent in addition to the vinyl monomer having a solubility parameter of 7 to 10. It is preferable to use a polyfunctional monomer together. Such polyfunctional monomers include polyvinyl aromatics such as divinylbenzene, polyvinyl heterocycles such as divinylpyridine, ethylene glycol dimethacrylate or diacrylate, diethylene glycol such as triethylene glycol dimethacrylate or diacrylate. Methacrylates or diacrylates can be used. When these cross-linking agents are used, if the amount is too small, the effect of cross-linking cannot be obtained, and if the amount is too large, the oil absorption capacity of the polymer decreases, so 0.01 to 50% by weight in the porous vinyl polymer. To be used.

The porous vinyl polymer is prepared by mixing one or more of the above-mentioned vinyl monomers having a solubility parameter of 7 to 10 with a non-polymerizable organic solvent, and dispersing and suspending this mixture in water according to a conventional method. Alternatively, it can be produced by emulsion polymerization and then drying the obtained polymer under reduced pressure to vaporize and remove the non-polymerizable organic solvent.

As the non-polymerizable organic solvent, toluene,
Aromatic hydrocarbons such as benzene, aliphatic hydrocarbons such as n-hexane and n-octane, halogenated hydrocarbons such as dichloroethane and trichloroethylene, ethyl acetate,
Esters such as butyl acetate can be used. Among them, aliphatic hydrocarbons and aromatic hydrocarbons, which are good solvents for vinyl monomers having a solubility parameter of 7 to 10 and poor solvents for porous vinyl polymers, can be preferably used. The amount of the organic solvent used is preferably such that the monomer / organic solvent ratio is 1/1 to 1/4 (weight ratio).

The oil-absorbing powder of the component (B) as described above does not include titanium dioxide microcapsules as described in JP-A-6-116129.
That is, since a powder made of only such an inorganic compound has a low oil absorption property, it cannot fully support the oily ultraviolet absorber of the component (A), and therefore is not included in the oil absorption powder of the present invention. Absent.

The amount of the oil-absorbent powder used is preferably 0.01 to 50% by weight, more preferably 0.05 to 5% by weight, based on the UV protective cosmetic composition. If the amount of the oil-absorbing substance used is less than 0.01% by weight, it becomes impossible to carry a sufficient amount of the ultraviolet absorber, and if it exceeds 50% by weight, it remains white on the skin after use.
It is not preferable because it reduces the feeling of use.

Examples of the aqueous medium of the component (C) used in the ultraviolet protective cosmetics of the present invention include water, monohydric alcohols such as methanol, ethanol and isopropanol, ethylene glycol, propylene glycol, dipropylene glycol, 1 , 3-butylene glycol,
Glycols such as 1,4-butylene glycol and isopropylene glycol, and alkyl ethers thereof,
Glycerins such as glycerin, diglycerin, and triglycerin can be used, and these can be used alone or in combination of two or more. Further, maltose, maltose, sucrose, fructose, xylitol, sorbitol, maltotriose, threitol, erythritol, sugars such as glucose, polyethylene glycol, polyoxyethylene methyl glucoside and the like can be appropriately mixed in the aqueous medium.

The amount of the aqueous medium used is usually from the viewpoint of the ultraviolet protection ability and the feeling of use per the amount of the ultraviolet protective cosmetics used.
It is preferably 75% by weight or more of the UV protective cosmetic.

The UV protective cosmetic composition of the present invention is a two-phase cosmetic composition obtained by mixing such an aqueous medium with the oil-absorbing powder carrying the above-mentioned oil-based UV absorbent. Here, with the two-phase cosmetics, the oil-absorbent powder carrying the ultraviolet absorber is easily and uniformly dispersed in the aqueous medium by shaking gently, but they are separated by leaving it standing. Then, both of those having a two-phase state and those having a stable dispersed state of the oil absorbing powder carrying the ultraviolet absorber and the aqueous medium are included. However, since it does not include emulsifying systems, in this respect conventional makeup cosmetics (Japanese Patent Publication 6)
2-51931) is clearly distinguished.

The UV protective cosmetic composition of the present invention comprises (A) an oily UV absorbent, (B) an oil absorbing powder, and (C) an aqueous medium, as well as various components to the extent that the effects of the present invention are not impaired. Can be included.

For example, in order to adjust the feeling of use, in addition to the oil-absorbing powder of component (B) described above, an inorganic powder having an average particle size similar to that of the oil-absorbing powder may be used in combination. it can. Examples of such inorganic powders include mica, talc, sericite, kaolin, zinc oxide and the like. In addition, the oil absorption capacity is 0.5 to adjust the feeling of use.
Natural or synthetic organic polymers of less than ml squalene / g can also be used in combination.

Further, it is possible to contain general components which are blended in cosmetics such as anti-inflammatory agents, antioxidants, preservatives and fragrances.

As a method of using the ultraviolet protection cosmetic composition of the present invention, an appropriate amount may be applied to the skin in the same manner as a lotion.

The UV protective cosmetic composition of the present invention can be obtained by mixing the respective components according to a conventional method. First, the oily ultraviolet absorber of the component (A) and the oil absorbing powder of the component (B) are mixed. It is preferable that the oil-based ultraviolet absorber is supported on the oil-absorbing powder, and then the oil-absorbing powder supporting the oil-based ultraviolet absorber is mixed with the aqueous medium of the component (C). As a result, the oil-based ultraviolet absorber can be sufficiently absorbed by the oil-absorbent powder and can be carried, and thus the oil-based ultraviolet absorber can be favorably dispersed in the aqueous medium without using an emulsifier as an essential component. Become. Therefore, it is possible to greatly improve the usability.

When these three components (A), (B) and (C) are mixed at the same time, the oil-based ultraviolet absorber does not sufficiently support the oil-absorbing powder, so that the components do not disperse well,
It becomes difficult to obtain the desired two-phase cosmetics.

When the oil-based UV absorber of component (A) and the oil-absorbent powder of component (B) are mixed to support the oil-based UV absorber on the oil-absorbent powder, the oil-based UV absorber has a viscosity at room temperature. In the case of a liquid of low liquidity, it is sufficient to simply mix both. When the oily ultraviolet absorber is a highly viscous liquid or solid, the solvent may be mixed with the oil-absorbent powder using a solvent such as ethanol, and then the solvent may be dried and removed.

[0038]

The ultraviolet protection cosmetic composition of the present invention contains (A) an oily ultraviolet absorber, (B) an oil absorbing powder and (C) an aqueous medium. Here, the oil-based ultraviolet absorber of the component (A) is (B)
The oil-absorbing powder carried by the oil-absorbing powder, and carrying the oil-based ultraviolet absorber is dispersed in the aqueous medium of the component (C) to form a two-phase cosmetic composition. Therefore, the ultraviolet protective cosmetic of the present invention is a cosmetic of an aqueous medium that does not contain an emulsifier as an essential component. Therefore, the ultraviolet protection cosmetic composition of the present invention has an excellent feeling of use without stickiness. In addition, after being applied to the skin, it will not easily run off by sweat or the like, and the durability of the ultraviolet protection effect will be improved.
