Description

Hair cosmetics

The present invention relates to a cosmetic for hair.

Hair dyes are divided into permanent hair dyes (permanent hair dyes, etc.) that color the hair by using oxidative dyes, and semi-permanent hair dyes (acidic hair dyes, etc.) that are colored by allowing the hair to penetrate and absorb direct dyes. ), temporary hair dyes (mascara for hair, etc.) that are colored by forming a colored film containing colorants (mainly pigments) on the hair. Among them, the temporary hair dye has less damage to the hair, can be easily removed by shampooing, and can be used simply, so it is better as a hair dye that can easily enjoy the fun of dyeing hair. As the previous temporary hair dyes, the following temporary hair dye compositions are known: for fixing the coloring agent as a colored film on the hair, and imparting water resistance to the colored film, and preventing damage to the skin or clothing. Migration, and contains a film-forming polymer.

Previously, the mainstream of temporary hair dyes were those aimed at black hair. From the viewpoint of being easy to apply to the hairline and other areas of concern, mascara-type ones are known as product forms. For example, Patent Document 1 contains titanium oxide black with higher safety, and can be dyed with relatively little unevenness or fading, and has relatively little secondary pollution. It can achieve a good balance between usability and usability. Temporary dyeing of wool, reveals the following temporarily dyed wool, which contains 35 to 80% by mass of ethanol, titanium oxide black, (methacryloxyethyl carboxybetaine/alkyl methacrylate) copolymer, and hydroxypropyl Base cellulose, and glycerin. It is also recorded that this temporary hair dye can sufficiently reduce the scattering of liquid even when a brush is used as an applicator, so it is particularly suitable as a mascara-type temporary hair dye, and when applying the dye to the target part of the hair In this case, the viscosity is preferably 50 to 30000 mPa·s.

In addition, as an applicator for efficiently applying liquid cosmetics to the hair or for applying in a narrow area that becomes the area to be applied, Patent Documents 2 and 3 disclose the following cosmetic applicator: on the application area It is provided with an elastic body-containing application member and a plurality of comb teeth that can be impregnated with liquid cosmetics, and has a specific shape.

＜Container and applicator＞ As shown in FIGS. 1 and 2, the hair cosmetic 100 is one having a container 1 and an applicator 2 containing a liquid hair cosmetic L inside. In the embodiment shown in Figs. 1 and 2, the container 1 of the hair cosmetic 100 is inserted into the applicator 4 side of the applicator shaft 3 of the applicator 2, and the applicator 4 is immersed in the liquid contained in the container 1 The hair cosmetics L.

As shown in FIGS. 2 to 4, the applicator 2 is provided with an applicator 4 on one end of the applicator shaft 3 and a container cover 5 on the other end of the applicator shaft 3. The applicator 4 is a member for applying the hair in a state of being impregnated with liquid hair cosmetics L in contact with the hair.

The application shaft 3 only needs to have a substantially columnar or substantially cylindrical shaft extending from the container cover 5 in the direction of the application body 4. The cross-sectional shape of the shaft portion of the application shaft 3 is not particularly limited. From the viewpoint of holding the application body 4 so as to be rotatable around the circumference of the application shaft 3 as described later, the shaft portion of the application shaft 3 is preferable It is roughly cylindrical. The material of the application shaft 3 is not particularly limited, but from the viewpoints of molding processability, light weight, etc., plastics such as polyethylene and polypropylene are preferred.

The applicator 4 is provided with an absorbent member with a density of 15 kg/m ³ or more and 95 kg/m ³ or less. The applicator 4 may be composed of an absorbent member, or may be partially equipped with comb teeth, brushes, etc., in addition to the absorbent member. From the point of view that it is difficult to produce dripping or lack of liquid when applying liquid hair cosmetics to the hair, it can be applied from the roots of the hair to the tips of the hair in a single operation. The above-mentioned absorbent member of the applicator 4 The coverage ratio is preferably 50% or more of the outer surface of the applicator 4, more preferably 70% or more, still more preferably 90% or more, and still more preferably 100%. From the point of view that it is difficult to produce dripping or lack of liquid when applying liquid hair cosmetics to the hair, and from the point of view that it is applied from the roots of the hair to the tips of the hair in one operation, the applicator 4 is preferably absorbent Component builder. In this specification, the term “absorbent member” refers to a member that can impregnate and retain liquid hair cosmetics L and other liquids, and as a representative form of the absorbent member, a sponge can be cited. In the present invention, if the density of the absorbent member provided in the applicator 4 provided in the applicator 2 is within the above range, the liquid hair cosmetic has good retention and spreadability and can be applied to the roots of the hair with one operation Apply evenly to the ends of the hair. From the viewpoint of the retention of liquid hair cosmetics, the density of the absorbent member is 15 kg/m ³ or more, preferably 20 kg/m ³ or more, more preferably 22 kg/m ³ or more, and more Preferably, it is 25 kg/m ³ or more. In addition, from the viewpoint that it is difficult to produce drips during the application operation of relatively low-viscosity hair cosmetics, and will be applied uniformly, the density of the absorbent member is 95 kg/m ³ or less, preferably 93 kg /m ³ or less, more preferably 90 kg/m ³ or less. The specific range of the density of the absorbent member is 15 to 95 kg/m ³ , preferably 20 to 95 kg/m ³ , more preferably 22 to 93 kg/m ³ , and still more preferably 25 to 90 kg/m ³ . Here, the density is a rectangular parallelepiped cut from the absorbent member, the weight W (kg) and the lengths L, M, and H (m) of the three sides of the vertical, horizontal, and height are measured, and calculated according to the following formula. Density (kg/m ³ )=W/(L×M×H) Furthermore, when the absorbent member is impregnated with liquids such as hair cosmetics, it may absorb the liquid hair cosmetics and swell, so it is absorbent The above-mentioned density of the member is measured using the absorbent member in a dry state. Hereinafter, the outer diameter, inner diameter, thickness, and length of the absorbent member covering the entire circumference of one end of the application shaft 3 are similarly measured using the absorbent member in a dry state.

Here, the outer diameter of the absorbent member refers to the cross section of the absorbent member perpendicular to the longitudinal direction of the application axis (hereinafter also referred to as the "application axis direction") passing through its center of gravity and having both ends at the outer edge of the cross section. The length of the longest straight line in the straight line is shown by d1 in Figure 3. For example, if the shape of the outer circumference in the cross-section perpendicular to the application axis direction of the absorbent member is a perfect circle, it means the diameter of the perfect circle. The so-called inner diameter of the absorbent member refers to twice the shortest distance from the center of gravity of the cross section perpendicular to the application axis direction of the absorbent member to the inner surface of the absorbent member, as shown by d2 in FIG. 3. For example, if the shape of the inner circumference in the cross section perpendicular to the application axis direction of the absorbent member is a perfect circle, the inner diameter of the absorbent member is equal to the diameter of the perfect circle. The so-called thickness of the absorbent member refers to (the outer diameter of the absorbent member-the inner diameter of the absorbent member)/2. The so-called length of the absorbent member refers to the length of the absorbent member in the application axis direction and the length of the part that can contact the hair, as shown by h in FIG. 3.

The outer diameter of the absorbent member can be set to various required outer diameters according to the size of the hair cosmetics. From the viewpoint of easy carrying of hair cosmetics and easy application of hair cosmetics to hair, the outer diameter of the absorbent member is preferably 5 mm or more, more preferably 8 mm or more, and still more preferably 10 mm or more, Furthermore, it is preferably 35 mm or less, more preferably 25 mm or less, and still more preferably 15 mm or less. The specific range of the outer diameter of the absorbent member is preferably 5 to 35 mm, more preferably 8 to 25 mm, and still more preferably 10 to 15 mm. From the viewpoint of good liquid retention of liquid hair cosmetics and suppression of dripping during use, the thickness of the absorbent member is preferably 0.5 mm or more, more preferably 1 mm or more, and more preferably 1.5 mm or more Moreover, it is preferably 8 mm or less, more preferably 6 mm or less, and still more preferably 4 mm or less. The specific range of the thickness of the absorbent member is preferably 0.5-8 mm, more preferably 1-6 mm, and still more preferably 1.5-4 mm. The length of the application axis direction of the absorbent member can be set to various lengths according to the extent to which the width of the hair cosmetics that can be applied with one operation is set. From the viewpoint of having the liquid retention of the liquid hair cosmetics and making the spreadability of the hair cosmetics good, the length of the application axis direction of the absorbent member is preferably 10 mm or more, more preferably 15 mm or more, and further It is preferably 20 mm or more, more preferably 60 mm or less, more preferably 50 mm or less, and still more preferably 40 mm or less. The specific range of the length in the application axis direction of the absorbent member is preferably 10-60 mm, more preferably 15-50 mm, and still more preferably 20-40 mm.

The material of the absorptive member is not particularly limited as long as the density is within the above-mentioned range and can be impregnated and maintained in the liquid hair cosmetic L. It has the liquid retention of the liquid hair cosmetic and the compressibility suitable for application. From the viewpoint of elasticity, such as responsiveness, the material of the absorbent member is preferably polyurethane. That is, the absorbent member is preferably a sponge made of polyurethane such as foamed polyurethane.

The application body 4 shown in FIGS. 2 to 4 is a state in which the above-mentioned absorbent member is formed. As shown in FIGS. 2 to 4, the applicator 4 composed of the above-mentioned absorbent member is provided at one end of the applicator shaft 3, and the absorbent member in the applicator 4 covers the entire circumference of one end of the applicator shaft 3. The so-called "full circumference of one end of the application shaft" refers to the entire side of the application shaft at one end of the application shaft. That is, the absorbent member does not cover only a part of the side surface of the application shaft 3 at one end of the application shaft 3, but covers the entire side surface of one end of the application shaft 3. By setting one end of the application shaft 3 as an absorbent member to cover the entire circumference, the retention of the liquid hair cosmetics and the area that can contact the hair can be increased, so it will not cause a lack of fluid in the middle of application. The liquid hair cosmetics can be applied uniformly in one operation. Especially for long hair, when applying hair cosmetics in a way that draws slender lines from the roots of the hair to the tips of the hair, compared to a flat-shaped applicator, the applicator of this embodiment can be applied to narrow areas Smearing is therefore advantageous in that it is easy to apply to the target area and can be applied uniformly in one operation without causing lack of fluid.

For example, when the applicator shaft 3 has a substantially cylindrical shaft extending in the direction of the applicator body 4, the applicator body 4 may be provided with a substantially cylindrical absorbent member covering the entire circumference of one end of the applicator shaft 3 .

The smear body 4 is preferably at one end of the smear shaft 3 and is held so as to be rotatable around the circumference of the smear shaft 3. The circumferential direction of the application axis refers to the circumferential direction when the application axis 3 has a substantially cylindrical shaft portion, for example. If the applicator 4 is held to be able to rotate around the circumference of the applicator shaft 3, when applying hair cosmetics, press the applicator 4 against the hair surface and move it in a direction substantially orthogonal to the axial direction of the applicator shaft 3. With 2, the applicator body 4 can be applied while rotating around the circumference of the applicator shaft 3. In this aspect, the contact area between the surface of the applicator 4 and the surface of the hair with the absorbent member impregnated with the liquid hair cosmetic material L is increased, so that it is difficult to cause a lack of liquid during the application operation, and it can be used in one operation without unevenness. The effect of smearing is further improved.

As an aspect of maintaining the smear body 4 to be rotatable around the circumferential direction of the smear shaft 3, for example, the following aspect may be mentioned: as shown in Figs. 2 and 3, the smear shaft 3 is provided on the outer surface of the smear shaft 3 so as to be able to rotate around the smear shaft The rotating body 6 including the non-absorbent member that rotates in the circumferential direction of 3 is provided with an applicator 4 on the outer surface of the rotating body 6 and one end side of the applicator shaft 3. As the non-absorbent member constituting the rotating body 6, it is preferable to be plastic such as polyethylene or polypropylene similarly to the application shaft 3 and the container cover 5. The rotating body 6 shown in Figs. 2 and 3 is substantially cylindrical in shape, is provided so as to cover the outer circumference of at least one end of the smear shaft 3, and is held on the smear shaft 3 in a state rotatable around the circumference of the smear shaft 3 The other end is the container lid 5 side. By fitting the applicator body 4 having a substantially cylindrical absorbent member on the outer surface side of the rotating body 6 from one end side of the applicator shaft 3, the applicator body 4 is held so as to be rotatable around the circumferential direction of the applicator shaft 3 . Furthermore, in order to prevent the applicator 4 fitted in the rotating body 6 from falling off, it is preferable to use the applicator holder 7 to hold the applicator 4 to the rotating body 6. The applicator holder 7 shown in FIGS. 2 to 4 has a protrusion on one surface of the disc-shaped member, and the protrusion is fitted from the end face 3a (not shown) side of one end of the applicator shaft 3 to hold the applicator 4 Does not fall off. The outer diameter of the disc-shaped member can be appropriately selected within the range that realizes the holding of the applicator 4 without hindering the applicating operation of the applicator.

The container cover 5 is provided at the other end of the application shaft 3, and serves as a part for the user to hold when the cover of the container 1 and the application tool 2 are used. The container lid 5 shown in FIG. 5 has a substantially cylindrical shape with an opening on one side, and a screw-fitting connection with the male thread 1a of the container 1 shown in FIG. 5 is formed on the inner periphery near the opening. Female thread 5a. By inserting the application shaft 3 from the opening of the container cover 5, the container cover 5 and the application shaft 3 are locked so as not to rotate in the circumferential direction. The material of the container lid part 5 is not particularly limited, but from the viewpoints of moldability, light weight, etc., it is preferable to use plastic such as polyethylene or polypropylene similarly to the application shaft 3.

On the other hand, the shape and material of the container 1 are not particularly limited as long as the liquid hair cosmetic L within the above-mentioned viscosity range can be contained in the container 1, and it is preferably a bottle shape. The material of the container 1 may be the same as or different from that of the application shaft 3 and the container cover 5, but it is preferably the same as the application shaft 3 and the container cover 5 to be plastic such as polyethylene or polypropylene.

As shown in FIGS. 2 and 5, the container 1 preferably contains a liquid hair cosmetic material L, and the neck of the container 1 is provided with a squeezing member 8. The squeezing member 8 is formed of a soft material such as rubber, and has a substantially cylindrical shape with a bottom, extending downward from the neck of the container 1. At the bottom of the squeezing member 8, a slit (cut) 8a having a cross shape is formed, for example, and a circular plate is provided at a position higher than the bottom and lower than the neck of the container 1 so as to protrude inward.之捋取部8b. At the approximate center of the scraping portion 8b, a circular scraping hole 8c for passing the application shaft 3 and the application body 4 is formed.

According to the hair cosmetic 100 having such a configuration, the applicator 4 is immersed in the liquid hair cosmetic L in a state where the applicator 2 is attached to the container 1. Also, in this state, the application shaft 3 passes through the picking hole 8c and the slit 8a, and the slit 8a is in a downwardly curled state.

Then, the user holds the container lid 5, releases the screwing between the female thread 5a of the container lid 5 and the male thread 1a of the container 1, and takes out the applicator 2 from the container 1. At this time, the excess hair cosmetic material L attached to the applicator body 4 of the applicator 2 is swept down by the inner peripheral surface of the swabbing portion 8b that forms the swabbing hole 8c, and is swept down by the slit 8a.

When the applicator 2 is taken out from the container 1, the crimp of the crimped cross-shaped slit 8a is restored, and the bottom is substantially closed. Therefore, when the applicator 2 is taken out from the container 1 and is being used for application, even if the container 1 is accidentally dumped, it will be blocked by the closed slit 8a, and the liquid hair cosmetic L can be prevented from flowing out of the container 1.

Furthermore, it is preferable that the container 1 contains the stirring ball 9 together with the liquid hair cosmetic L as shown in FIG. Even when the blended components such as colorants in the hair cosmetics precipitate, the container 1 can be shaken by the user's hands or the like, and the stirring ball 9 can be used to efficiently stir and uniformly redisperse. The material of the stirring ball 9 is preferably a material that has a high specific gravity and is difficult to wear. For example, SUS (Steel Use Stainless, Japanese stainless steel standard) can be cited.

＜Hair cosmetics＞ The liquid hair cosmetic L contained in the container 1 has a viscosity of 5,000 mPa·s or less at 25°C. In the hair cosmetics of the present invention, by setting the viscosity of the hair cosmetics contained in the container 1 to the above range and using the applicator 2 described above, it is difficult to produce dripping or lack of liquid during the application operation, and one operation can be used. Apply the cosmetics for the hair from the roots of the hair to the tips of the hair without unevenness. The viscosity of the hair cosmetics at 25°C needs to exceed 0 mPa·s. From the viewpoint of suppressing dripping or splashing of liquids during the application operation, it is preferably 1 mPa·s or more, and more preferably 5 mPa·s s or more, and more preferably 10 mPa·s or more, from the viewpoint of increasing the amount held in the smear body and applying it from the root of the hair to the tips of the hair in one operation without causing a lack of fluid , Preferably 3,000 mPa·s or less, more preferably 2,000 mPa·s or less, still more preferably 1,500 mPa·s or less, still more preferably 1,000 mPa·s or less, still more preferably 800 mPa·s or less, and further It is more preferably 500 mPa·s or less, still more preferably 300 mPa·s or less, and still more preferably 150 mPa·s or less. The specific range of the viscosity of hair cosmetics at 25°C is 5,000 mPa·s or less, preferably more than 0 mPa·s and 5,000 mPa·s or less, more preferably 1 to 3,000 mPa·s, and more preferably 1 ～2,000 mPa·s, more preferably 5～1,500 mPa·s, still more preferably 5～1,000 mPa·s, still more preferably 5～800 mPa·s, still more preferably 5～500 mPa·s, It is still more preferably 5 to 300 mPa·s, still more preferably 10 to 300 mPa·s, and still more preferably 10 to 150 mPa·s. Furthermore, the above-mentioned viscosity is measured at a specific rotation speed and temperature of 25±1℃ for 1 minute by using a B-type viscometer with a rotor corresponding to the measurement range. Specifically, 70-80 g of hair cosmetics are added to a spiral tube with a capacity of 100-200 mL, and shaken by hand with an amplitude of about 30 cm for 100 times for 30 seconds in a uniform manner, and further, once per second After making it upside down 30 times at the speed, immediately use the B-type viscometer (TV-10M, manufactured by Toki Sangyo Co., Ltd.), use rotor No. M1 when the viscosity is below 100 mPa·s, and use rotor No. M1 at a rotation speed of 100 rpm. Use rotor No. M2 when the viscosity is in the range of 100 to 500 mPa·s, measure the viscosity under the condition of 60 rpm, and use rotor No. when the viscosity is in the range of 500 to 2,000 mPa·s. M3, the viscosity is measured at a rotation speed of 60 rpm. When the viscosity is in the range of 2,000 to 10,000 mPa·s, the rotor No. M4 is used to measure the viscosity at a rotation speed of 60 rpm. In more detail, the viscosity can be measured by the method described in the examples.

The hair cosmetics constituting the hair cosmetics of the present invention are preferably hair dyes, more preferably temporary hair dyes. When the hair cosmetic is a hair dye, especially a temporary hair dye, the hair cosmetic preferably contains the following components (A) to (C). (A) Coloring agent (B) Film-forming polymer with silicone structure (C) Non-aqueous solvent

(Component (A): Coloring agent) The coloring agent as component (A) is used to dye the hair into a desired hue when the hair cosmetic is a hair dye. As a coloring agent, a pigment and a dye can be mentioned, and these can also be used together. Particularly, from the viewpoint of being a temporary hair dye that imparts bright colors to hair, the component (A) is preferably a pigment. As the pigment, either an inorganic pigment or an organic pigment may be used, or these may be used in combination.

The component (A) used in the present invention preferably contains an interference pearlescent pigment (A1) and a coloring agent (A2) other than the interference pearlescent pigment. If component (A) is a composition containing component (A1) and component (A2), it is used as a temporary hair dye for hair cosmetics, especially for the purpose of improving fashionability and imparting bright colors to the hair. In this case, it can make the coloring behavior difficult to be affected by the hair color of the base and give a certain hair dyeing effect. The so-called "color development behavior is difficult to be affected by the base hair color to give a certain hair dyeing effect", more specifically refers to whether the base hair color is bright or dark, the color change corresponding to the applied color is not It will greatly change the brightness (brightness) of the hair before and after dyeing.

In hair dyes such as temporary hair dyes, colorants such as pigments are usually used. However, for example, with regard to temporary hair dyes that only use organic pigments as colorants, it is difficult to see the color change if dark hair such as black hair is dyed. Therefore, in order to obtain sufficient color development, a large number of blending machines are required. pigment. On the other hand, if temporary hair dyes with a large amount of organic pigments are applied to bright-colored hair such as bleached hair, the color will be too gorgeous and impractical. The inventors conducted diligent studies and found that by using interference pearlescent pigments as the component (A1) and a coloring agent (component (A2)) other than the component (A1) as the colorant component, the color development behavior can be hardly affected by the substrate. The effect of hair color gives a certain dyeing effect.

The interference pearlescent pigment as component (A1) refers to a pigment that exhibits a pearlescent luster by the reflection and interference of light and has a coating on the surface of the core particle. The coating includes a reflective interference layer and has translucency. . The core particles are usually translucent plate-shaped particles, and the reflective interference layer contains colorless metal oxides such as titanium dioxide or colorless metals. In addition, depending on the thickness of the reflective interference layer included in the coating, the color of the wavelength derived from the reflected light may appear, but the coating itself is translucent. As a result, even if the component (A1) is applied to light-colored hair alone, it is difficult to see the color change, but if it is applied to dark-colored hair, it will be given a shiny luster based on the reflection and interference of light, and it is easy to see at the same time. A change in color. Therefore, it is considered that if component (A1) is used, even if coloring agents such as organic pigments as component (A2) are not blended in large amounts, a temporary hair dye that exhibits sufficient color development when applied to dark hair is obtained. In addition, when the temporary hair dye is applied to bright-colored hair, it can impart the desired color without drastically changing the brightness of the hair. It is believed that under the above action mechanism, the color development behavior can be hardly affected by the hair color of the base, and a certain hair dyeing effect can be imparted.

[Interference Pearlescent Pigment (A1)] The interference pearlescent pigment is a pigment that exhibits pearlescent luster by the reflection and interference of light as described above, and is provided with a coating on the surface of the core particle. The coating includes a reflective interference layer and has translucency. In the present invention, the coating in the interference pearlescent pigment does not substantially contain ferrous metal oxides and non-ferrous metals. Furthermore, the so-called "substantially free" means that the coating does not contain any non-ferrous metal oxides and non-ferrous metals in the range that make the coating's own light transmittance disappear, and the non-ferrous metal oxides and non-ferrous metals in the coating The content is preferably 3% by mass or less, more preferably 1% by mass or less, and still more preferably 0.1% by mass or less. Examples of non-ferrous metal oxides include iron oxide, copper oxide, cobalt oxide, chromium oxide, nickel oxide, etc., and examples of non-ferrous metals include gold and copper. In this manual, interference pearlescent pigments and colored pearlescent pigments are distinguished. Colored pearlescent pigments are pigments that exhibit pearlescent luster by the reflection and interference of light. They usually have a coating on the surface of the core particles. The coating is colored by the above-mentioned non-ferrous metal oxides or non-ferrous metals, so it does not have light transmission. Sex.

＜Liquid retention capacity＞ Measure the weight of the applicator before impregnating the hair cosmetics and the weight of the applicator after impregnating the hair cosmetics into the applicator by the above method, and calculate the amount of liquid retained by the applicator based on the difference between the weights before and after the impregnation of the hair cosmetics (Liquid retention). The liquid holding capacity (g) is rounded to the third place after the decimal point, and is shown in Table 3 and Table 4.

＜Good degree of liquid retention＞ After the hair cosmetic material is impregnated in the applicator body of the applicator by the above method, the applicator is tilted so that the applicator axis becomes horizontal, and the applicator is allowed to stand for 15 minutes, and visually observe whether there is dripping of the hair cosmetic. Furthermore, the presence or absence of dripping of liquid (dripping from the spontaneous tress or dripping from the applicator) when applied to the aforementioned hair tress for evaluation was visually observed by 5 evaluators, and evaluated using the following evaluation criteria. [Evaluation Criteria and Score] 1 The applicator that has been tilted and left to stand after the liquid has been held, and none of the evaluators have observed dripping of the liquid during the smearing operation 2 The applicator that has been tilted and left to stand still has no liquid dripping since the liquid is held, but any one of the evaluators observed the dripping of the liquid during the smearing operation (tolerable level in actual use) 3 The dripping of the liquid has been observed on the applicator that has been tilted and left to stand after the liquid has been kept

＜The length of dyeing with one application＞ After the hair cosmetic is impregnated in the applicator body of the applicator by the above-mentioned method, it is applied from the root of the hair bundle for evaluation to the direction of the hair tip, and the length of dyeing with one application is measured. The length (cm) dyed by one application is rounded to the first place after the decimal point, and shown in Table 3 and Table 4.

＜Whether there is uneven dyeing with one application＞ After the hair cosmetic is impregnated in the applicator body of the applicator by the above-mentioned method, the applicator is applied from the root to the tip of the hair bundle for evaluation in a single application and allowed to air dry. About the hair tresses after application, 5 professional sensory inspectors visually observed the presence or absence of dye unevenness, and evaluated them using the following evaluation criteria. The scores based on the following evaluation criteria are shown in Tables 3 and 4. [Evaluation criteria] a Even completion effect b There is a slight uneven staining (no agglomerates of the colorant are observed, but there is a part that is not evenly stained) c There is obvious uneven dyeing (confirmed agglomerates of colorant) [Assessment criteria and scores] 1 There are 0 people who give a rating of "c", and there are 2 or more people who give a rating of "a" 2 There are less than 1 person who gives a rating of "c", and less than 1 person who gives a rating of "a" 3 There are more than 2 people who gave the evaluation of ``c''
