Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a make-up cosmetic which allows the face to be washed while applying makeup without the makeup coating film being transferred to clothes. More specifically, by using the cohesive force, the adhesive force and the adhesive force of the oily component of the fine particle powder, a film with a strong bond with the skin is formed and the transfer of the powder to clothes is suppressed. In addition, the present invention relates to makeup cosmetics for washing the face after sports with makeup applied.

[0002]

BACKGROUND OF THE INVENTION Conventionally, foundations have functions such as coloring agents such as iron oxide, hiding agents such as titanium oxide, extender pigments such as talc, resin powder and ultrafine titanium oxide. It consists of a powder and an oil.

These powders are fixed to the skin by the adhesive force of the powder itself and the binding force of the oil agent. However, their adhesive strength and bonding strength are generally weak,
It was not possible to prevent transfer of the decorative coating film to clothes or hands.

Particularly, when a plate-like powder such as talc is used, there is a problem that the transfer of the makeup coating film to clothes or hands increases.

In addition, even when a fluorine compound such as perfluoropolyether or fluorine-treated powder, which is often used in "lasting type" cosmetics in recent years, is used, the binding force between the powder and the skin is basically used. Was weak and could not prevent the transfer of the makeup coating film to clothes and hands.

On the other hand, the present inventors have found that in a slurry system in which fine particle powder is strongly dispersed in a solvent to form smaller secondary particles, strong aggregation of the fine particle powder occurs when the solvent evaporates. The use of force provides a strong bond between the skin and the pigment that replaces traditional binders,
By using this binding force, the makeup coating does not transfer to clothes,
It was found that a makeup cosmetic that can wash the face with makeup applied can be obtained.

Further, they have found that by simultaneously mixing trimethylsiloxysilicic acid having a strong adhesive force and acrylic silicone as an oily component, a makeup cosmetic having a stronger binding force to the skin can be obtained.

Therefore, according to the present invention, a cosmetic coating film is obtained by using an oily component having a strong cohesive force and a strong adhesive force of the fine particle powder in combination, and not using a powder which is easily transferred such as a plate-like powder. It is an object of the present invention to provide a makeup cosmetic that allows the face to be washed while applying makeup without being transferred to clothes.

The makeup cosmetic according to claim 1, wherein the makeup cosmetic is in the range of.

The structure of the present invention will be described in detail below. The fine particle powder used in the present invention has a primary particle size in the range of 5 to 350 nm. The primary particle size can be measured by observation with a transmission electron microscope (TEM) or scanning electron microscope (SE).
M) Use the particle size obtained from observation. When the shape of the fine particle powder is spherical, the diameter of the sphere is defined as the particle diameter, and when it is needle-shaped or rod-shaped, the minor diameter is defined as the particle diameter. In the case of an irregular type, the average particle size from the center is used as the particle size. Further, as the relationship between the particle size distribution and the primary particle size, when the particle size distribution is narrow, the average primary particle size may be used as the particle size. It is necessary to distinguish between the bodies.

In the fine particle powder used in the present invention, a powder having a primary particle size of less than 5 nm is not preferable because it is active and unstable and may cause problems such as alteration of cosmetics. A powder having a primary particle size of more than 350 nm lacks a cohesive force as a fine particle powder, and therefore the amount to be blended must be limited.

The fine particle powder used in the present invention is 3 to 60 parts by weight with respect to 100 parts by weight of makeup cosmetics,
It is preferably 5 to 40 parts by weight. Below 3 parts by weight,
The effect of the fine particle powder is not sufficient, and when it exceeds 60 parts by weight, there is a problem that the viscosity increases too much, which is not preferable. If factors such as touch are added to these problems, 5-4
A range of 0 parts by weight is especially preferred.

The fine particle powder used in the present invention is 15 to 10 based on the total weight of the powder incorporated in the makeup cosmetic.
It is preferable to add 0%, more preferably 30 to 100%. Further, the primary particle size is 10 to 100.
When it is specified as a fine particle powder having a particle size in the range of nm, it is particularly preferable that it is contained in the range of 25 to 100% of the total weight of the powder contained in the makeup cosmetic. Where 2
If it is less than 5%, there arises a problem that the transfer rate increases.

The fine particle powder used in the present invention comprises a white powder and a colored powder. As white powder, titanium oxide,
Examples thereof include zinc oxide, aluminum oxide, silicon dioxide, zirconium oxide, calcium carbonate, barium carbonate and barium sulfate. It should be noted that the titanium oxide may be of a crystalline type such as rutile, anatase or amorphous, or an amorphous type. Further, as the colored powder, an inorganic powder,
It does not matter if it is an organic powder. For example, yellow iron oxide, red iron oxide, black iron oxide, iron-containing titanium oxide, lower titanium oxide,
Cerium oxide, cobalt oxide, cobalt titanate, lithium cobalt titanate, titanium / titanium oxide sintered body, copper chlorophyll, porphyrin compound, gold, silver, platinum,
Examples thereof include carbon black, silicon carbide, organic dyes and organic dyes.

Each of these materials may be compounded or may be compounded with a powder of aluminum oxide, silicon dioxide, zirconium oxide or the like. Further, surface treatment such as silicone treatment, fluorine compound treatment, silane coupling agent treatment, acylated lysine treatment, fatty acid treatment, metal soap treatment, amino acid treatment and the like may be performed, but fine particles of highly active powder are used. Since it is used, it is preferable that a surface treatment or a composite treatment is performed in order to improve safety.

Among these surface treatments, a preferable method is, for example, an alkylalkoxysilane treatment. Alkylalkoxysilanes include R ¹ _X Si
(OR ² ) _4-X (wherein R ¹ is an alkyl chain having 4 to 10 carbon atoms, R ² is an alkyl chain having 1 to 3 carbon atoms or a side chain, and X is 1 to 3). The compound represented by the general formula (1) can be used. Examples of the surface treatment method include a method of forming a gas phase composite of titanium tetraisopropoxide and a method of mixing and heating an alkylalkoxysilane and fine particle powder. Carbon number 4-10
The presence of the alkyl chain in the surface of the fine particles can suppress sedimentation and caking of the fine particle powder in the cosmetic with the passage of time, and further improve redispersibility. In addition, the powder which has been surface-treated with an alkylalkoxysilane has good compatibility with trimethylsiloxysilicic acid and acrylic silicone, and precipitation,
It is also important that reactions such as aggregation do not occur.

The fine particle powder used in the present invention may be dried and dehydrated before use. Since fine particle powder is generally easy to absorb moisture, the transfer rate and viscosity may change depending on the amount of moisture absorption.

Of these fine particle powders, colored powders such as iron oxide / titanium oxide sintered products and dye-dyed powders are preferable because color separation in cosmetics is less likely to occur. The shape is preferably spherical from the viewpoint of obtaining a strong cohesive force, but may be needle-shaped, rod-shaped, or amorphous.

Further, as an example of a method for producing fine particle powder,
Various methods such as a gas phase method, a liquid phase method and a plasma method can be mentioned, but any method may be used. Further, as a result of the difference in cohesive force between the fine particle powders depending on the production method, the secondary particle diameter is often greatly different, but in the present invention, only the primary particle diameter is provided, provided that the transfer rate is within the specified range. If it is within the specified range, the size of the secondary particle size does not matter.

In the makeup cosmetic of the present invention, the concept of "transfer rate" is proposed. The transfer rate referred to in the present invention indicates the degree to which a cosmetic transfers to another substance, and can be measured by the following method.

(Method of measuring transfer rate) Filter paper (manufactured by Toyo Roshi Kaisha, Ltd.)
Two pieces of quantitative filter paper 5A (diameter 125 mm) are prepared, and 0.1 g of make-up cosmetics is evenly dropped or applied to the center of the filter paper A within a circle with a radius of 1.5 cm, and at 40 ° C. 1
After drying for 0 minutes, the L ^* value when the color of the central part is measured with a color difference meter is L1, and the L ^* value of the portion where the makeup cosmetic is not applied is L0. Then, insert another filter paper B into filter paper A.
Then, the filter paper A and the filter paper B are slowly moved by 3 cm while the weight of 1 kg is applied to the center of the filter paper B having a radius of 1.5 cm. L2 is the average value of the L ^* values when the filter paper A and the filter paper B were peeled off and the vicinity of the portion of the filter paper B that was in contact with the filter paper A and had the largest transfer amount was measured at several points. When the transfer rate is T (%), it can be expressed by T = [(L2-L0) / (L1-L0)] × 100.

When measuring the transfer rate, it should be noted that the data may differ depending on the colorimetric method. The present inventors have adopted a method of increasing the number of samples and measurement points using CMS-1500 type (measurement probe diameter: 3 mm) manufactured by Murakami Color Research Laboratory, and obtaining an average value thereof. Also, be careful when applying a weight of 1 kg, but it is preferable to apply a load using a rubber stopper or silicone stopper having a diameter of 3 cm. When a load is applied with metal, wood, hard plastic, or the like, the way the load is applied becomes uneven, and there is a problem that the value of the transfer rate tends to vary.

The transfer rate range used in the present invention is 0.
.About.25%. It is preferably 0 to 20%, more preferably 0 to 10%. Transfer rate is 25
If the value exceeds%, the color will be transferred to clothes, but 0 to 10%
In the case of the range, even if it is rubbed many times with clothes, the color transfer is hardly noticeable.

In the makeup cosmetic of the present invention, it is possible to use various powders conventionally used in cosmetics as powders other than fine particle powders, but especially resin powders are used. Is preferred. For example, nylon beads,
Silicone beads, urethane beads, Teflon beads,
Styrene beads, acrylic resin, silicone resin powder,
Cellulose powder, silk powder and the like can be mentioned, but nylon beads, silicone beads and urethane beads are particularly preferable.

Examples of powders other than resin powders include yellow iron oxide, red iron oxide, black iron oxide, chromium oxide, cobalt oxide, ultramarine blue, navy blue, zinc oxide, titanium oxide, zirconia oxide, and silicon oxide. , Aluminum oxide, cerium oxide, titanium mica, barium sulfate, calcium carbonate, magnesium carbonate, aluminum silicate, magnesium silicate, pigment,
Examples include lake dyes, and surface treatments such as silicone treatment, fluorine compound treatment, silane coupling agent treatment, silane treatment, organic titanate treatment, acylated lysine treatment, fatty acid treatment, metal soap treatment, oil treatment, amino acid treatment and the like. You may give it. However, when a plate-like mineral such as sericite is used as powders other than the resin powder, this reduces the transfer-preventing effect of the makeup cosmetic of the present invention, and also causes color darkening. It is necessary to use less. The amount of the plate-like mineral compounded is preferably 0.1 to 3 parts by weight with respect to 100 parts by weight of the cosmetic.

The solvent used in the present invention must contain cyclic silicone in view of the relationship between the volatilization rate and the cohesive force. Examples of the cyclic silicone include octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane.

Other solvent components include ethanol,
Lower alcohols such as isopropyl alcohol, isoparaffins, hexameric and higher cyclic silicones, tetramethyltetrahydrogencyclotetrasiloxane, ethers, LPG, fluorocarbons, N-methylpyrrolidone, freons, fluoroalcohols, volatile linear silicones, etc. However, it is not particularly limited as long as it has a function as a solvent and there is no safety problem.

However, when water is contained, the growth rate of the film of the cosmetic material extends in the direction perpendicular to the skin, so that the transfer rate tends to increase. Therefore, it is preferable not to add water. The water content adsorbed on the fine particle powder and blended as a part of the fine particle powder is to be considered separately from this value.

The amount of the solvent component mixed with the cyclic silicone is preferably 20 to 95 parts by weight, more preferably 30 to 100 parts by weight with respect to 100 parts by weight of the makeup cosmetic.
85 parts by weight.

The invention requires a strong dispersion treatment in which the fine powder is crushed using a strong mechanical crushing force. That is,
The fine particle powder usually forms and stabilizes secondary agglomerates, and the cohesive force between the particles is significantly reduced as compared with the primary particles alone. It is necessary to break this secondary agglomerate in order to give a stronger cohesive force when the cosmetic is used. As a method of mechanical crushing, a roller mill or a preferred method is used.
Ku is a continuous, strong grinding force wet medium type pulverizer, even
For example, paint conditioners, bead mills, sand mills, dyno mills, micros, diamond fine mills, and other equipment with strong crushing power. As the grinding medium of the wet medium type grinder, for example, alumina, zirconia,
Examples thereof include glass beads, but are not particularly limited.

In the present invention, the above wet pulverizer may be used as it is in order to obtain a solution-type makeup cosmetic, but when obtaining a semi-solid makeup cosmetic, a dry pulverization may be used. Since there is a problem that it is difficult to obtain the force, it is preferable to use a method such as flushing for substituting the solvent after the wet pulverization, or distilling or sucking the solvent after filling the container with a solution-like bulk. Further, it is possible to obtain a solid makeup cosmetic by further removing the solvent, but there is a problem because the transfer rate specified in the present invention is exceeded.

As the method for producing a makeup cosmetic of the present invention, a strongly dispersed slurry or paste of fine particle powder for each color is prepared, and the mixture is mixed by changing the mixing ratio for each color of the product. The method is preferred.

In the present invention, in addition to powders, oils, surfactants, ultraviolet absorbers, adhesives, bactericides, preservatives, antioxidants, anti-inflammatory agents, vitamins, fragrances, which have been used in cosmetics in the past, are used. It is possible to mix pigments and dyes. here,
Of the various components that are blended in cosmetics, powder, fine particle powder,
The components other than the solvent, the dye, and the dye are collectively called the oily component.

The mixing ratio of the powder component such as fine particle powder, resin powder, and powder to the oil component is, for example, powder component 10
It is preferable that the oil component is in the range of 1 to 100 parts by weight, more preferably 5 to 40 parts by weight, based on 0 parts by weight.

In the present invention, the oily components include trimethylsiloxysilicic acid and acrylic silicone. The total compounding amount of trimethylsiloxysilicic acid and acrylic silicone is 3 to 4 with respect to 100 parts by weight of makeup cosmetics.
It is preferably 0 part by weight. Trimethylsiloxysilicic acid and acrylic silicone help fix the powder, and acrylic silicone has a weak nonionic surface-active function, so it helps prevent the powder from aggregating in the solvent. Here, if it is less than 3 parts by weight, the ability to fix the powder is not sufficient, and if it exceeds 40 parts by weight, there is a problem that the feel is deteriorated.

The trimethylsiloxysilicic acid and acrylic silicone used in the present invention are preferably those dissolved in a solvent such as cyclic silicone or isoparaffin.

The acrylic silicone used in the present invention refers to organopolysiloxanes in which an organic functional group having an acrylic group and / or a methacrylic group is introduced into a side chain and / or a terminal of a siloxane chain, and the molecular weight and modification rate are particularly limited. Not done. Here, the modification rate refers to the ratio of the number of siloxanes introduced with an organic functional group to the total number of siloxanes. As the acrylic silicone, it is possible to use the one that has been conventionally used for hair setting agents etc. as it is, but since the offensive odor caused by the impurities derived from the organic functional group becomes a problem, the operation for reducing the impurities is performed. Preferably.

Examples of the oily component include higher alcohols such as cetyl alcohol, isostearyl alcohol, lauryl alcohol, hexadecyl alcohol and octyldodecanol, fatty acids such as isostearic acid, undecylenic acid and oleic acid, glycerin, sorbitol and ethylene. Polyhydric alcohols such as glycol, propylene glycol, polyethylene glycol, myristyl myristate, hexyl laurate, decyl oleate,
Esters such as isopropyl myristate, hexyldecyl dimethyloctanoate, glyceryl monostearate, diethyl phthalate, ethylene glycol monostearate, octyl oxystearate, liquid paraffin,
Hydrocarbons such as petrolatum and squalane, lanolin, reduced lanolin, waxes such as carnauba wax, mink oil, cocoa butter,
Examples include oils and fats such as coconut oil, palm kernel oil, camellia oil, sesame oil, castor oil and olive oil, and ethylene / α-olefin / co-oligomers.

As another example of the oily component of another form,
For example, dimethylpolysiloxane, methylhydrogenpolysiloxane, methylphenylpolysiloxane, polyether-modified organopolysiloxane, perfluoroalkyl / polyoxyalkylene co-modified organopolysiloxane, alkyl-modified organopolysiloxane, terminal-modified organopolysiloxane, fluorine-modified Organopolysiloxane, amodimethicone, amino-modified organopolysiloxane, silicone gel, acrylic silicone,
Examples thereof include trimethylsiloxysilicic acid, silicone compounds such as silicone RTV rubber, and fluorine compounds such as perfluoropolyether, fluorinated pitch, fluorocarbon, and fluoroalcohol.

Examples of the surfactant include anionic surfactants, cationic surfactants, nonionic surfactants,
Although a betaine-type surfactant can be used, it is preferable not to use it because it reduces sebum resistance and sweat resistance.

Examples of organic UV absorbers include para-aminobenzoic acid (hereinafter referred to as PABA), 2-ethylhexyl para-methoxycinnamate, 2-ethylhexyl para-dimethylaminobenzoate, 2-hydroxy-4-methoxybenzophenone, and the like. 2-hydroxy-4-methoxybenzophenone-5-sulfuric acid, 2,2'-dihydroxy-
4-methoxybenzophenone, p-methoxyhydrocinnamic acid diethanolamine salt, ethyldihydroxypropyl PABA, glyceryl PABA, homomenthyl salicylate, methyl-O-aminobenzoate, 2-ethylhexyl-2-cyano-3,3-diphenylacrylate, octyldimethyl. PABA, octyl methoxycinnamate, octyl salicylate, 2-phenyl-benzimidazole-5-sulfate, triethanolamine salicylate, 3- (4-methylbenzylidene) camphor, 2,4
-Dihydroxybenzophenine, 2,2 ', 4,4'-
Tetrahydroxybenzophenone, 2,2'-dihydroxy-4,4'-dimethoxybenzophenone, 2-hydroxy-4-N-octoxybenzophenone, 4-isopropyldibenzoylmethane, butylmethoxydibenzoylmethane, 4- (3,4 -Dimethoxyphenylmethylene) -2,5-dioxo-1-imidazolidine propionate 2-ethylhexyl (soft shade DH,
Ajinomoto) and the like.

Among these oily components, in addition to trimethylsiloxysilicic acid and acrylic silicone, HLB value of 0.5
To polyoxyalkylene-modified organopolysiloxane of 6 to 6, perfluoroalkyl / polyoxyalkylene co-modified organopolysiloxane having HLB value of 0.5 to 6, dimethylpolysiloxane, methylphenylpolysiloxane,
One or more selected from high-polymerization degree dimethylpolysiloxane, fluorine-modified organopolysiloxane, petrolatum, squalane, octyl oxystearate, ethylene / α-olefin / co-oligomer, and organic UV absorber are added to the makeup cosmetic composition. Preferably. These oily components have a strong tendency to reduce the transfer rate or enhance the ultraviolet protection effect, as compared with other oily components. Here, when the HLB value is less than 0.5, there is a problem that the function as the modified silicone is lost, and when the HLB value exceeds 6, there is a problem that the water resistance becomes weak.

Examples of the makeup cosmetics of the present invention include foundations, makeup bases, eyeshadows, mascaras, correction cosmetics such as filter colors, sunscreens and the like, but sports applications are particularly preferable. Furthermore, local dyeing (fashion dyeing) is also possible. The form of the cosmetic may be liquid, spray, or mousse.

The make-up cosmetic composition of the present invention forms a dense film on the skin, and therefore has a higher UV protection effect than conventional products. Therefore, depending on the prescription, S
The PF value can be set.

[0050]

The present invention will be described in detail below with reference to Examples and Comparative Examples. The evaluation methods of the examples and comparative examples used in the present invention are as follows.

Measurement of transfer rate The method of measuring the transfer rate is as described above.

Sensory evaluation Twenty female panelists aged 20 to 40 were made to use the cosmetics prepared in Examples and Comparative Examples, and the transferability of the cosmetics to tissue paper and whether or not it was possible to wash the face only with water We obtained responses in a questionnaire format for two items. Before using the cosmetic, a double face wash was performed, and then the prototype was evaluated with the skin being dry.

The transferability to tissue paper (tissue-off property) was used as an index of transferability by using the total number of panelists who answered that transfer was difficult or difficult. Therefore, it is indicated that the larger the number, the more difficult the transfer is.

Regarding the face-washing property, whether the face-washing with water alone is possible or not was taken as an index of the face-washing property by the number of panelists who answered that the cosmetics did not collapse after the face-washing. Therefore, the larger the number is, the more the face can be washed.

[0073]

[Table 6]

[0074]

[Table 7]

From the results of Tables 6 and 7, it can be seen that the examples of the present invention have lower transfer rates than the comparative examples.
From the comparison between Examples 1 and 2, it can be seen that the blending of the resin beads slightly increases the transfer rate, but has little effect on the intended quality. In Comparative Example 1, an example of using a plate-like powder instead of using fine particle titanium oxide is shown.
The face-washing property was poor. Further, in Comparative Example 2, in order to investigate the influence of trimethylsiloxysilicic acid and acrylic silicone, the same compounding amount as that in the Example was set. Although the transfer rate was certainly low, it was found that the transfer rate was not reached.

Further, when the redispersion state of Examples 2 and 3 after being allowed to stand for 2 months was observed, it was found that Example 3 was superior in redispersibility.

[0077]

From the above, it is clear that the present invention provides a makeup cosmetic that allows the face to be washed with makeup without transferring the makeup coating to clothes.
