Patent Application
20230255860
The present invention relates to a paint material composed of a cosmetic, a diluent for the paint material, a paint, and a paint set. More specifically, the present invention relates to the paint material composed of a cosmetic that can use a cosmetic and the like to be discarded, the diluent for the paint material, the paint, and the paint set.
The cosmetic including powdery cosmetic is distributed, and is mainly used by females. Typical powdery cosmetic includes a base makeup such as a foundation and a face powder, and a point makeup such as an eye shadow and a blusher, and these are all used for purposes of smearing on human skin or the like. In addition, most of powders such as extender powders constituting the powdery cosmetic are derived from minerals (see, for example, Patent Literature 1), but some minerals are faced with a problem of depletion.
On the other hand, individual consumers often discard the powdery cosmetic without using it up, and companies that manufacture and sell cosmetic also discard a large amount of bulk (contents) of the powdery cosmetic that have not cleared a certain quality in a year. Even in view of a recent situation in which a sustainable society should be aimed at, an effective use of the powdery cosmetic to be discarded should be considered, and an establishment of a technology corresponding thereto is desired.
Here, in many cases, a pigment or a bright powder is blended in the cosmetic such as the powdery cosmetic, and in this case, there is a characteristic that a wide variety of colors can be visually enjoyed. If the powdery cosmetic to be discarded can be converted into, for example, a paint while having related characteristics, a new use method of the powdery cosmetic to be discarded can be provided.
Generally, an oily component (an oil solution) such as a silicone oil or a hydrocarbon oil, extender powders such as a mica, a talc, a silica, a barium sulfate, or a synthetic phlogopite, a coloring material such as a titanium dioxide, and a surfactant or the like as necessary are blended in the powdery cosmetic, and these are often packed and pressed in a container such as a gold dish.
For this reason, there is a case where the powder in the powdery cosmetic is partially covered with the oily component of a certain amount, and even when the powdery cosmetic is pulverized and kneaded with a commercially available aqueous liquid, a wetting does not proceed and the powdery cosmetic is separated, so that it is difficult to form the powdery cosmetic into a slurry like a paint.
The present invention has been made in view of the above, and it is an object of the present invention to provide the paint material composed of a cosmetic that can be used in the same manner as a commercially available typical watercolor paint, the diluent for the paint material, the paint, and the paint set.
In order to solve the above problems, the paint material composed of the cosmetic according to the present invention includes:
the extender powders and the coloring material, and
when contained components are arranged in a descending order of a content, the cosmetic having three or less oily components in the top five places is included.
In the present invention described above, when the contained components are arranged in the descending order of the content, the paint material composed of the cosmetic according to the present invention includes one or more of the extender powders in the top three places.
In regard to the paint material composed of the cosmetic according to the present invention, in the present invention described above, the extender powders included in the top three places are at least one selected from the group consisting of the mica, the talc, the synthetic phlogopite, the silica, and the barium sulfate.
In regard to the paint material composed of the cosmetic according to the present invention, in the present invention described above, a pearl powder is not included in the top three places when the contained components are arranged in the descending order of the content.
In regard to the paint material composed of the cosmetic according to the present invention, in the present invention described above, the cosmetic is at least one selected from the group consisting of the eye shadow, the blusher, a body powder, the face powder, a bleaching powder, a skincare powder, a loose powder, a presto powder, and the foundation.
The diluent for the paint material according to the present invention is the diluent for diluting the paint material composed of the cosmetic and includes components below:
a water of 49.5 to 89.0 mass % with respect to the entire diluent;
a lower alcohol of 10.0 to 35.0 mass % with respect to the entire diluent; and
a polyvinyl alcohol of 0.5 to 15.0 mass % with respect to the entire diluent.
In regard to the diluent for the paint material according to the present invention, in the present invention described above, the lower alcohol is an ethanol.
The paint according to the present invention includes
a mixture obtained by mixing:
the paint material composed of the cosmetic of the present invention described above; and
the diluent for the paint material according to the present invention described above.
The paint set according to the present invention includes:
the paint material composed of the cosmetic of the present invention described above; and
the diluent for the paint material according to the present invention described above.
When used in combination with the diluent for the paint material, the paint material composed of the cosmetic according to the present invention has the minimum properties as the paint and can be used in the same manner as a typical paint, which can achieve the effective use of the cosmetic to be discarded. In particular, by using such diluent in combination, it is possible to expect good characteristics peculiar to the paint material based on the cosmetic in terms of a transparency, a quick-drying property, a smell, and the like of a film when the paint material is stretched and spread on a piece of drawing paper as compared with the typical paint.
When the diluent for the paint material according to the present invention is used in combination with the paint material composed of the cosmetic, the diluent for the paint material can play a role of compensating for the component insufficient as the paint material with respect to the cosmetic for the paint material.
The paint and the paint set according to the present invention include the paint material composed of the cosmetic according to the present invention and the diluent for the paint material according to the present invention, and can be provided as the paint that can be used in the same manner as the typical paint and as the paint set in which the paint material and a dedicated diluent are included.
Hereinafter, one aspect of the present invention will be described.
Although the present invention is the paint material composed of the cosmetic, examples of the cosmetic that is considered to be applicable to the present invention among the commercially available cosmetics include, the cosmetic having the powdery cosmetic such as various eye shadows (eye colors) that include a powder eye shadow (an eye color), various blushers (cheek colors) that include a powder blusher, the body powder, the face powder, the bleaching powder, the skincare powder, the loose powder, the presto powder, and makeup cosmetics (makeup) that include the foundation; and a cosmetic having the powdery cosmetic such as base cosmetics serving as a base of the makeup cosmetic that include a cosmetic base.
These cosmetics may be used alone, or may be used in combination of two or more thereof. In addition, there is no problem even if these cosmetics to be discarded are used, and by using the cosmetic originally scheduled to be discarded, the effective use of the cosmetic to be discarded can be achieved.
Among these, the eye shadow (the eye color) is, for example, the cosmetic that is applied to form a shadow by attaching colors of different tones to eye holes on eyelids side and a periphery of eyes such as lower eyelids and outer corners of the eyes.
The blusher (the cheek color) is a so-called cheek rouge (a blush) and is a cosmetic used to make one's complexion look bright by applying to a cheek or to create a three-dimensional effect by shading the cheek. A dosage form may be a solid form, a powder form, a cream form, a liquid form, a stick form, and the like, and the powder form is suitable for the present invention.
The body powder is a cosmetic used for suppressing a glare of oil and giving a natural finish with a mat.
The face powder is a cosmetic used for finishing makeup and for suppressing a so-called gleaming (shininess) and stickiness of sebum and the foundation. The bleaching powder having a whitening effect, the skincare powder having a skincare effect, and the loose powder are also considered to be one kind of the face powder and the body powder.
A breast powder is a kind of the face powder described above, and is basically used after using the foundation described later. It is a cosmetic for conditioning and coating the foundation to make one's skin look more beautiful.
The foundation is a cosmetic used to condition the color of the skin or to cover freckles, stains, and the like of the skin to protect the skin from ultraviolet rays. It is the makeup cosmetic to be applied after applying the cosmetic base described later on the skin.
The cosmetic base is used as a base before applying the makeup cosmetic such as the foundation, and is a cosmetic as a base material to be used for the purpose of bettering a color development property, an adhesion force (an adhesion), and a spreadability (a covering) of the makeup cosmetic, preventing a beauty of a makeup finish and a makeup deterioration, and maintaining a makeup effect.
Additionally, the powdery cosmetic suitable for the paint material according to the present invention generally refers to the cosmetic that has the powder (the powder component) as a main component (it is considered that the content is mostly 60 mass % or more of the entire cosmetic, and is preferably 60 to 95 mass %, but is not limited thereto) and is appropriately mixed with an aqueous component, the oily component, or the like as necessary, and such powdery cosmetic is understood to refer to the cosmetic having powder particles with a particle diameter of approximately 1.0 mm or less and allowing each particle to freely flow at a normal temperature and a normal pressure, but is not particularly limited thereto and can widely use the cosmetic generally called the powdery cosmetic in the cosmetic industry.
Examples of the component contained in the cosmetic to be an object represented by the above include the extender powders (for example, an inorganic powder, an organic powder, a surfactant metal salt powder (metallic soap), and the like), the coloring material (for example, an inorganic pigment, an organic pigment, a natural pigment, the pearl powder, and the like), the oily component (for example, natural vegetable oils and animal oils, the hydrocarbon oil, an ester oil (including a glyceride oil), a higher fatty acid, a higher alcohol, the silicone oil, a wax, an oil thickener, an organic solvent, and the like), and other components (for example, an aqueous preservative, a powder preservative, a preservative, a surfactant, a surface treatment agent, an antioxidant, a cosmetic agent, an ultraviolet absorber, a film-forming agent, an emollient component, an aqueous component, and the like). These components may be used alone, or may be used in combination of two or more thereof. Further, similarly for each of the components listed below, they may be used alone, or may be used in combination of two or more thereof. Among them, the extender powders and the coloring material are essential components for applying the cosmetic as the paint material, but the oily component and the other components are not particularly limited as described above. Further, as for the oily component, as will be described later, when the contained components in the cosmetic are arranged in the descending order of the content, the number of types of the oily component is set to three or less among the top five places.

The above cosmetic applicable to the present invention preferably contains the coloring material, and when the contained components are arranged in the descending order of the content, the cosmetic preferably contains one or more of the extender powders in the top three places. Since the coloring material contained in the cosmetic often has a brightness and the extender powder also serves as a base material of the paint material and often assists the color development, the coloring material is suitable for use as the paint material and various colors can be visually enjoyed by using the extender powder as the essential component. In addition, the extender powder has a function of accommodating a hiding power, a coloring power, a covering power, a spreadability, the adhesiveness, and the like when the extender powder is spread on the drawing paper as the paint.
In addition, the coloring material is mostly contained in an amount of preferably 0.05 mass % or more and particularly preferably 2.0 to 30.0 mass % with respect to the entire cosmetic, but the coloring material is not particularly limited to this range as long as it has the color development suitable for the use as the paint material. Further, in a case where an insufficient color development or the like is felt when the cosmetic is applied as the paint material, the coloring material may be separately added to obtain the content described above.
While the extender powder contained in the cosmetic is suitable as the paint material as described above, in the case where one or more of the extender powders are contained in the top three places in the descending order of content of the contained components, it is considered that the extender powders can be expected to be appropriately contained in the cosmetic, and the entire cosmetic can be effectively used as the paint material.
Further, when the contained components of the extender powders are arranged in the descending order of the content, the extender powders more preferably occupy two of the components in the top three places, and particularly preferably occupy all three of the components in the top three places. Moreover, when the contained components are arranged in the descending order of the content, the extender powders more preferably include the extender powders in the top two places, and particularly preferably include the extender powder in the top one place.
In addition, when the contained components are arranged in the descending order of the content, the extender powders included in the top three places are preferably at least one selected from the group consisting of the mica, the talc, the silica, the synthetic phlogopite (the synthetic fluorofurogopite), and the barium sulfate (the sulfate Ba). These extender powders are bulky powders with a large oil supply amount and are suitable as the paint material, and when used as the paint material, the hiding power, the coloring power, the covering power, the spreadability, the adhesiveness, and the like when spread on the paper can be accommodated. In other words, it is possible to impart a uniformity of adhesion to a surface of the paper, a smoothness of a finished paint film, a visual transparency, and the like.
In the cosmetic to be targeted, when the contained components are arranged in the descending order of the content, the number of the oily components is set to three or less from the top five places. When four or more kinds of the oily components are contained from the top five places, it is considered that a ratio of the oily component to the cosmetic is high, and even if it is mixed with the diluent for the paint material (which will be described in (II) described later) to be used in combination, the diluent is not compatible with the cosmetic and is separated, which becomes unpreferable since the same state as that of the commercially available typical watercolor paint cannot be obtained. In addition, even in a case where the cosmetic and the diluent seemingly can be mixed, a slight separation from the diluent is present, and when the cosmetic is dissolved in the water and smeared on the drawing paper, it may be difficult to use the cosmetic as the paint, which is not preferable. When the contained components in the cosmetic are arranged in the descending order of the content, the number of the oily components is preferably two or less, more preferably one or less, and particularly preferably zero (with no oily components) in the top five places.
In addition, when the contained components are arranged in the descending order of the content, it is preferable that the pearl powder does not appear in the top three places. Since the pearl powder such as a pearlescent pigment (a pearl agent) and a glitter pigment (a lame agent) is formed from powders having a relatively large particle diameter, when the pearl powder appears in the top three places as the coloring material, there is a possibility that a proportion of the pearl powder with respect to the cosmetic increases, and when the pearl powder is formed into the paint, there is a possibility that the pearl powder adversely affects the stretch and a spread on the drawing paper, an over-coating on the drawing paper, the smoothness of the film formed on the drawing paper, and a fixability of the film formed on the drawing paper, and further, there is a possibility that a secondary adhesion is lowered. When the contained components are arranged in the descending order of the content, the pearl powder more preferably does not appear in the top two places, and particularly preferably does not appear in the top place. Further, in regard to the present invention, it is recognized that the “secondary adhesion” refers to an evaluation item rather than a phenomenon, and a performance and a superiority of the evaluation item are described. In other words, the fact that the secondary adhesion becomes low and the secondary adhesion becomes poor indicates that the secondary adhesion is likely to occur when regarded as an event.
The contained components preferably contain at least one selected from the group consisting of the titanium dioxide, the zinc oxide, and the boron nitride. These components are considered to be general-purpose components because they are usually contained in the makeup cosmetic or the like.
In addition to the above components, the components generally used in the cosmetic, for example, desired components generally used in the cosmetic such as drugs, moisturizers, disinfectants, and resins can be added to the cosmetic to be used in the present invention as long as the object and effect of the present invention are not impaired.
In order to use the paint material composed of the cosmetic according to the present invention as a watercolor paint, for example, the paint material is mixed with the diluent for the paint material to be described later (as the mixture) to form the paint. Here, forming into the paint refers to a state similar to that of the commercially available typical watercolor paint (like the paint) (the same applies hereinafter). In addition, after the paint is formed, the paint is dissolved in an appropriate amount of the water and smeared on the drawing paper with a brush in the same way as the commercially available typical watercolor paint (hereinafter, it may be simply referred to as the “typical paint”).
When used in combination with the diluent for the paint material, the paint material composed of such cosmetic according to the present invention has the minimum properties for the paint material, and can be used in the same manner as the typical paint, and the effective use of the cosmetic to be discarded can be achieved. In particular, by using such diluent in combination, it is possible to expect the good characteristics peculiar to the paint material based on the cosmetic in terms of the transparency, the quick-drying property, the smell, and the like of the film when the paint material is stretched and spread on the drawing paper as compared with the typical paint.
Further, when the cosmetic is formed into the paint as in the present invention (hereinafter, it may be referred to as a “cosmetic paint” for convenience), the cosmetic paint may be slightly inferior to the typical paint in the color development (the ease of developing colors). This is because a concentration of the pigment blended in the powdery cosmetic itself produced for the purpose of smearing on the human skin is lower than that of the typical paint.
In addition, depending on a type of the cosmetic to be formed into a paint, there may be a case where a slight decrease in the secondary adhesion (for example, a smeared and dried locus on the drawing paper can be traced with a hand, and can be confirmed whether the locus is attached to the hand or not) is observed as compared with the commercially available typical watercolor paint. The reason is considered to be the fact that the powders such as the extender powders blended in the cosmetic are relatively large as compared with the typical paint having a powder with the particle diameter of substantially the pigment grade.
On the other hand, for example, the film of drawing traces finished with the cosmetic paint has the transparency unique to the cosmetic paint, and may have a touch feeling with the transparency unique to the cosmetic paint, which is not provided in the typical paint. In addition, since the cosmetic paint is originally the cosmetic, it is considered to have a good smell and a quick-drying property and the like are also good by mixing it with the diluent described later.
Next, the diluent for the paint material (hereinafter, it may be simply referred to as the “diluent”) used in combination with the paint material composed of the cosmetic will be described. The diluent is suitable for being used in combination with the paint material or the like composed of the cosmetic according to the present invention described above, and contains the water, the lower alcohol, and the polyvinyl alcohol in which the content thereof is within a specific range. When the cosmetic or the like described above is applied as the paint material (the base material of the paint), such diluent for the paint material is used by being mixed with the cosmetic, thereby playing the role of compensating for the component insufficient as the paint material with respect to the cosmetic.
In other words, since the cosmetic such as the powdery cosmetic is not originally manufactured on an assumption of the paint material, it is natural that there are components insufficient for the typical paint. When the paint material or the like having the above components is used by being dissolved in the water as it is, it is expected that a dispersibility in water, a wettability to water, and the like are insufficient, and even if the paint material or the like is dissolved in water, the adhesiveness to paper, a coatability, the quick-drying property, and the like are insufficient. When the diluent for the paint material contains a specific amount of the above components, such insufficient properties can be supplemented.
The water serves as a solvent for dispersing each component constituting the diluent, and can use generally-used water such as a tap water, a purified water, an ion exchange water. The content of such water may be, for example, a balance (in the diluent, a moiety other than essential components and optional components) excluding the essential components and the optional components in the diluent, but is mostly 49.5 to 89.0 mass %, more preferably 60.5 to 86.0 mass %, and still preferably 66.5 to 83.5 mass % with respect to the entire diluent.
The lower alcohol plays a role as a volatile agent when used in combination with the cosmetic, and can impart a volatility and the quick-drying property. As the lower alcohol, for example, lower alcohols (a monohydric alcohol having 5 or less carbon atoms) such as a methanol (a methyl alcohol), the ethanol (an ethyl alcohol), a propanol (a propyl alcohol), an isopropyl alcohol, a butanol, a propanol can be used, and the ethanol is preferably used from the viewpoint of a versatility, a safety, a compatibility, and the like with the cosmetic.
The content of the lower alcohol is totally 10.0 to 35.0 mass % with respect to the entire diluent. When the content of the lower alcohol is less than 10.0 mass %, the quick-drying property is impaired, the film forming on the paper is delayed, and a color unevenness may occur. On the other hand, when the content is more than 35.0 mass %, the quick-drying property is too strong, and the film is formed without being stretched, which may also cause the color unevenness. Further, when the ethanol is used as the lower alcohol, an excessive ethanol may cause a pigment aggregation. The total content of the lower alcohol is more preferably 12.5 to 30.0 mass %, and is preferably 15.0 to 30.0 mass % with respect to the entire diluent.
The polyvinyl alcohol is useful for the film formation when used in combination with the cosmetic (which becomes a film component), and can impart the covering to the drawing paper, the smoothness to the film, and the like with respect to the film to be formed.
The content of the polyvinyl alcohol is 0.5 to 15.0 mass % with respect to the entire diluent. When the content of the polyvinyl alcohol is less than 0.5 mass %, the film to be formed becomes thin, and the smoothness and the uniformity of the film are lost. On the other hand, when the content exceeds 15.0 mass %, the film becomes thick, the uniformity of the film is damaged, and a finished film may be damaged by a friction. In other words, when the content is small, the film formed on the drawing paper becomes thin, such that irregularities of the powder become conspicuous and the uniformity of the film may be lost, and since the polyvinyl alcohol plays the role of dispersing the pigment, when the content is small, the pigment dispersibility of the paint itself or on the drawing paper at the time of the drawing may be deteriorated, and the color unevenness may occur. On the other hand, when the content is large, the film formed on the drawing paper becomes too thick, such that the uniformity of the film may be lost. The content of the polyvinyl alcohol is more preferably 1.0 to 9.0 mass %, and particularly preferably 1.0 to 3.0 mass % with respect to the entire diluent.
In addition to the essential components described above, the optional components such as a water-soluble film-forming agent and other water-soluble materials, for example, a water-soluble polymer such as the phenoxyethanol, a triethanolamine, a polyhydric alcohol, and a polyacrylic acid (a carbomer), a sodium hydroxide (NaOH), a potassium hydroxide (KOH) (a triethanolamine, the sodium hydroxide, and the potassium hydroxide described above serve as a neutralizing agent for the polyacrylic acid), a nonionic synthetic resin, a nonionic synthetic polymer, an acrylic acid-based water-soluble polymer, a polysaccharide, the surfactant, and the like can be appropriately added to the diluent for the paint material as long as the object and effect of the present invention are not hindered.
Here, it is preferable to solve the problem by using the surfactant for compensating the dispersibility, the wettability (wetting), and the like for the paint material composed of the cosmetic, but since the surfactant is often blended in the cosmetic such as the powdery cosmetic, which is considered to be a target of the paint material, the diluent is mentioned as the optional component in consideration of an influence on the environment and the safety when attached to the human skin when used as the paint. When the optional component is added, the optional component may contain, for example, about 1.0 mass % or less with respect to the entire diluent, but is not limited thereto.
The diluent for the paint material can be prepared by mixing and stirring the essential components and optional components mentioned above (the essential components and the like). As an example, each component may be added to the water to be the solvent, and the essential components and the like may be dispersed in the water by mixing and stirring.
When the diluent for the paint material according to the present invention described above is used in combination with the paint material composed of the cosmetic, the diluent for the paint material can play the role of compensating for the component insufficient as the paint material with respect to the cosmetic for the paint material.
The paint according to the present invention includes the mixture obtained by mixing the paint material composed of the cosmetic described in (I) and the diluent for the paint material described in (II), and similarly, the paint set according to the present invention includes the paint material composed of the cosmetic described in (I) and the diluent for the paint material described in (II). As the paint set, one kind of each of the paint materials and the diluent that compose of the cosmetic may be used, or two or more kinds thereof may be used.
The paint material composed of the cosmetic is diluted with the diluent for the paint material to form the mixture, such that the state similar to that of the commercially available typical watercolor paint (like the typical paint) is obtained (which is the paint of the present invention). A blending ratio of the paint material and the diluent is not particularly limited and can be appropriately determined according to the type of the cosmetic, a blending percentage of the components constituting the diluent, a color finally obtained by a user, and the like; but mostly, it is preferable to mix the diluent at 0.5 to 2 and particularly preferable to mix the diluent at 0.7 to 1.5 with respect to cosmetic 1 as a mass ratio, yet this range is not particularly limited.
The paint material diluted with the diluent (the paint as the mixture) is dissolved in the water on a pallet or the like and used, for example, as in the commercially available typical watercolor paint. The amount of the water to be used may be mostly, as a mass ratio, used in such a manner that the water is mixed and dissolved as 0.5 to 3 with respect to 1 of the diluted paint material (a cosmetic formed into a paint having the mixture of the cosmetic and the diluent), but is not limited to such a mixing ratio, and may be appropriately determined according to user's preference or the like.
The paint and the paint set according to the present invention explained above include the paint material composed of the cosmetic according to the present invention and the diluent for the paint material according to the present invention, and can be provided as the paint that can be used in the same manner as the typical paint and as the paint set in which the paint material and a dedicated diluent are included.
In addition, the aspects described above illustrate one aspect of the present invention, the present invention is not limited to the embodiments described above, and it goes without saying that modifications and improvements having the configuration of the present invention and within a scope of achieving the object and the effect are included in the content of the present invention. Further, a specific structure, a shape, and the like in carrying out the present invention may be other structures, shapes, and the like as long as the object and effect of the present invention can be achieved. The present invention is not limited to the embodiments described above, and the modifications and the improvements within the scope of achieving the object of the present invention are included in the present invention.
For example, in the embodiments described above, a certain type of cosmetic is exemplified as the type of cosmetic that can be used as the paint material, but the cosmetic that can be used as the paint material is not limited thereto, and an application of the cosmetic such as the powdery cosmetic other than those exemplified is not limited. Similarly, in the above embodiments, specific examples of each component are given but are merely examples, and there is no problem even if the component not given is blended in the paint material composed of the cosmetic.
In addition, the specific structure, shape, and the like at the time of carrying out the present invention may be other structures and the like as long as the object of the present invention can be achieved.
Hereinafter, the present invention will be described in more detail based on test examples and the like, but the present invention is not limited thereto.
16 kinds of commercially available cosmetics A to P having compositions shown in Tables 1 to 9 were prepared (Table 1 shows product names and types, and Tables 2 to 9 show all component information such as composition). The cosmetics A to P have the color development suitable for use of the coloring material as the component for the paint material (an evaluation is also performed in Test Example 2(4) described later).
Further, the cosmetics A to P contain the extender powders, the oily components, and the like, in which the cosmetics A to G and the cosmetics M to P are respectively classified into the eye shadows, the cosmetic H is classified into the blushers, the cosmetics I to K are classified into the face powders, and the cosmetic L is classified into the foundations.

Here, the compositions of Table 2 and the like are arranged in the descending order of the component amount with respect to the entire cosmetic. Further, in the compositions of Table 2 and the like, the display of “+/−” is a display used in a series product with many color differences such as the cosmetic for makeup, and indicates that the component (the coloring material or the like) displayed thereafter is used in the series product. Accordingly, the component that is not necessarily blended may be displayed in the cosmetic having a described product name (however, hereinafter at least one coloring material represented by the “+/−” is used).
Then, for the 16 kinds of the cosmetics, various properties of the paint material were compared and evaluated through the method described in [Test Example 2] using the diluent for the paint material selected in [Test Example 1] below.
Evaluation of the Diluent for the Paint Material:
The diluent for the paint material (the diluent) obtained through the following method was evaluated for a suitability as the diluent for the paint material using the cosmetic A as a control.
(Production of the Diluent for the Paint Material)
As the components of the diluent for the paint material, the water, the ethanol as the lower alcohol, the polyvinyl alcohol, and the phenoxyethanol were set to the contents (mass % with respect to the entire diluent) shown in Table 10, and other components were added to the water as the solvent, mixed, and stirred to be dispersed in the water, thereby producing diluents 1 to 3.
(Composition of the Diluent)
The diluent 1 to the diluent 3 thus obtained were formed into the paint (to be in the same state as the commercially available typical watercolor paint (like the typical paint)) through the method below using the cosmetic A listed in Tables 1 and 2, and then an evaluation sample was prepared, and the suitability as the diluent for the paint material was evaluated through the method below.
(Forming into the Paint and Preparing the Evaluation Sample)
The cosmetic (3 g) and the diluent (3 g) were kneaded with a spatula for five minutes to form the mixture, and the cosmetic was formed into the paint. Then, 0.2 g of the cosmetic formed into the paint and 0.2 g of the water (the tap water) were dissolved on the pallet to prepare the evaluation sample.
(Evaluation Method)
The evaluation samples were evaluated by 12 panelists according to the criteria shown in
Then, the calculated average scores were compared and evaluated using the evaluation criteria below. The results are shown in Table 11 (in Table 11 and Table 12 described later, the average scores of the results and evaluations of “⊙,” “◯,” “Δ,” and “x” are listed below). Additionally, in

(14) Solubility in Water after Solidification:
The paint was placed on the pallet in the same manner as (7), dried and solidified, and then whether the paint could be redissolved in water or not was confirmed.
(Results)
As shown in Table 11, according to the content of the lower alcohol (the ethanol) considered to be the volatile agent and the content of the polyvinyl alcohol (PVA) considered to be the film component, the results showed that the evaluation scores of (2) spread well (on paper), (3) quick-drying property, and (8) smoothness of film were increased (the diluent 3 is the highest). Further, regarding (5) transparency, all the three diluents gave the average score of 5 points (the full score).
On the other hand, regarding the evaluation of (1) extendibility (on paper), a standard score (3 points) or more of the typical paint was obtained, but the average score of the diluent 3 having the highest content of the ethanol and the polyvinyl alcohol was the lowest. In this respect, from the viewpoint of combining the volatility and a film formability, it is considered that there is an advantage that when the diluent 3 is used, the diluent 3 stretches and spreads to the extent of the typical paint, and a clean and uniform film can be quickly formed.
From the above results, it has been confirmed that all of the diluent 1 to the diluent 3 have the good characteristics equivalent to or better than those of the typical paint by relatively evaluating that the film of the paint does not extend too much when smeared on the drawing paper and stretches and spreads as much as the typical paint, that the film of the finished paint is neatly formed without being blurred as compared with the typical paint, and that the film of the finished paint is uniform and has less irregularities.
Then, among the three diluents, the diluent 3 having these characteristics in a well-balanced manner was determined to be the most preferable, and in the following [Test Example 2], the diluent 3 was used as the diluent.
Evaluation of the Cosmetic as the Paint Material:
For the cosmetics A to P shown in Tables 1 to 9 above, various properties of the paint material were compared and evaluated using the diluent 3 selected in Test Example 1 as the diluent.
First, similar to Test Example 1, 3 g of the cosmetic and 3 g of the diluent were kneaded with the spatula for five minutes to form the mixture, and the cosmetic was formed into the paint. In addition, 0.2 g of the cosmetic formed into the paint and 0.2 g of the water (the tap water) were dissolved on the pallet to prepare the evaluation sample.
As a result of the above operation, the cosmetic C, the cosmetic E, and the cosmetic F were separated from the diluent, and the diluent was not compatible with the cosmetic, such that the paint could not be formed (consequently, it could not be dissolved in the water and applied to the drawing paper). In addition, the cosmetic G was also found to be slightly separated from the diluent, and when the cosmetic G was dissolved in the water and smeared on the drawing paper, using the cosmetic G as the paint was difficult. Accordingly, it was determined that the cosmetic C, the cosmetic E, the cosmetic F, and the cosmetic G were not suitable as the paint material, and the subsequent evaluations were not performed.
With respect to whether the cosmetic can be formed into a paint or not, when four or more oily components are contained in the top five places based on the all component information of the cosmetic shown in Tables 2 to 9, it is considered that the cosmetic contains so many oily components that the entire surface area of the powder such as the extender powders is covered with the oily component, and forming the paint is considered to be difficult. In addition, all of the cosmetics that were difficult to be formed into the paint had the creamy dosage form, and were soft enough to be recognized as in a slurry form when touched with finger.
On the other hand, when the contained components are arranged in the descending order of the content, there is no problem in forming the paint or the like for the cosmetic A, the cosmetic B, the cosmetic D, and the cosmetic H to the cosmetic P, which are the cosmetic having three or less oily components in the top five places and one or more extender powders in the top three places. From the above, 14 evaluation items (see the above for the contents of the evaluation items) of the (1) to (14) below were evaluated on the evaluation samples of the cosmetic A, the cosmetic B, the cosmetic D, and the cosmetics H to P according to the criteria shown in
(Evaluation Items)
(1) Extendibility (on paper)
(2) Spread well (on paper)
(3) Quick-drying property
(4) Color development
(5) Transparency
(6) Over-coating (on paper)
(7) Peeling properties after drying
(8) Smoothness of film (formed on paper)
(9) Secondary adhesion
(10) Fixability of film (formed on paper)
(11) Smell
(12) Toning
(13) Solubility in water
(14) Solubility in water after solidification
(Results)
As shown in Table 12, some of the evaluated cosmetics were evaluated as “A,” for (4) color development and (9) secondary adhesion (for the cosmetic N, (1) extendibility (on paper), (6) over-coating (on paper), (8) smoothness of film (formed on paper), (10) fixability of film (formed on paper) is “A,” and (9) “secondary adhesion” is “x” will be described later), but the evaluation results were mostly good as a whole, and accordingly, it can be determined that the present cosmetic paint has the properties not much different from those of the typical watercolor paint.
Additionally, the items (1) to (14) are not essential characteristics for the paint and are merely confirmed to be relatively excellent and poor with respect to the typical paint, and the fact that the evaluation results of these items including the items (4) color development and (9) secondary adhesion are poor with respect to the typical paint does not mean that the cosmetic paint cannot be applied as the paint.
Here, for the (4) color development, some of the cosmetics (the cosmetic paints) that are evaluated as the paint this time are slightly inferior to the commercially available typical watercolor paint (the typical paint), because the content of the pigment blended in the powdery cosmetic itself produced for being smeared on the human skin may be lower than that in the typical paint.
However, regarding the (3) quick-drying property and the (5) transparency, the film of the drawing traces finished by the cosmetic paint has the transparency unique to the cosmetic paint, and comments of the panelists indicate that the film has the touch feeling unique to the cosmetic paint, which is not found in the typical paint and creates a preferable impression. From the above, although the color development is slightly inferior, it is considered that the cosmetic paint can be regarded as the paint, and a unique feeling of depiction can be presented by the touch with the transparency instead of the color development.
In addition, (9) secondary adhesion was slightly inferior to that of the typical paint in some cases. The reason is considered to be the fact that the powders such as the extender powders blended in the cosmetic is relatively large as compared with the typical paint having a powder with the particle diameter of substantially the pigment grade.
This is expected to be a state in which large powders contained in the cosmetic paint cannot enter the irregularities on the paper surface and adhere to the drawing paper surface as the film component, unlike the typical paint that enters the irregularities on the drawing paper surface in a soaked manner. Accordingly, it is considered that the film is easily entangled by a physical frictional force, and the secondary adhesion is lowered.
In addition, as described above, it has been confirmed that the (3) quick-drying property and the (5) transparency are evaluated to be better than the typical paint, and there are an advantage that a delicate design can be expressed by a light touch due to the transparency and another advantage that the drawing is easy due to the quick-drying property just like acrylic paint such that the drawing can be continued without waiting for the paint to dry.
Further, the evaluation of the (11) smell was also mostly better than that of the typical paint. The reason for this is that, although there are products with no smell and products with smell, the diluent itself does not have the smell unique to the watercolor paint, and further, the cosmetic paint formed by the cosmetic with smell is given a smell derived from the cosmetic and has the good smell unique to the cosmetic that does not give any discomfort.
Additionally, the cosmetic N containing the pearl powder as the largest content among all the components had a relatively low score in each item of (1) Extendibility (on paper), (6) over-coating (on paper), (8) smoothness of film (formed on paper), and (10) fixability of film (formed on paper), and a low score with the average score of 1 for (9) secondary adhesion.
This result is considered to be caused by the powder being caught on the brush tip because the pearl powder with larger particle diameter is contained in the largest amount among the components constituting the cosmetic. When the brush tip touches the paper, the large powder attached to the outer surface of the brush tip adheres to the paper, and the large powder is clogged between the brush tip at an initial stage of stretching and spreading, and the small powder is also clogged at the brush tip to be caught.
Thereafter, since only the component of the liquid form stretches and spreads to be sucked into the drawing paper, and the fluidity of the liquid component of the brush tip also decreases, it is considered that the extendibility of the paint is felt to decrease. From the above, it is considered that there is a bias in a localization of the powder in the drawing traces that extendibility on the drawing paper, (6) over-coating (on paper) becomes difficult, and the unevenness of the film of the drawing traces after drying also occurs. As a result, it is considered that (8) smoothness of film (formed on paper) is also affected, and (9) secondary adhesion is lowered and (10) fixability of film (formed on paper) is also lowered due to the lumps of the powder in which the drawing traces after drying are localized.
Additionally, the typical paint is usually used by putting the paint on the pallet, then drying and solidifying the paint. In order to verify whether the same use method for the typical paint is possible for the cosmetic paint as described above, (7) peeling properties after drying and (14) solubility in water after solidification were evaluated. As a result, as shown in Table 12, the paint was comparable to the typical paint, the peeling properties from the pallet and a poor solubility in the water were not confirmed, and it is confirmed that the paint could be used at the same level.
The present invention can be advantageously used as a means for applying the cosmetic to be discarded as the paint material or the paint, and has a high industrial applicability.
