The present invention relates to a method for treating a keratin substance or a fiber for a head decoration product.
Keratin substances are sometimes colored or decolored by artificial means for the purpose of improving fashionability, such as dyeing hair with a hair dye, bleaching hair with a bleaching agent, and dyeing nails with a manicure. However, the coloring or decoloring effect may be lost by friction due to daily living activities, discoloration with the passage of time, or one time washing, and methods for maintaining the coloring or decoloring applied to keratin substances or fibers for head decoration products such as wigs have been studied.
For example, JP 2013-541585 A (PTL 1) discloses a method for improving color retention in artificially colored hair, which includes applying to artificially colored hair a composition containing a hydrophobic particle substance having a predetermined particle diameter, a silicone-based hydrophobic film-forming agent, and a medium containing a volatile hydrocarbon or a silicone solution, in which a content of a non-volatile, water-soluble or water-dispersible organic component is less than a predetermined value.
The present invention relates to the following.
In the disclosed technique of PTL 1, it is described that the composition is applied to color-treated hair (wet hair or dry hair) after each shampoo. However, in this method, it is necessary to apply the composition to the hair every time shampooing is performed, and there is room for improvement in the durability of the coloring effect.
In addition, from the viewpoint of further improving the color durability by reducing the number of times of washing of the colored keratin substance, it is preferable that the keratin substance after the treatment can be provided with resistance to adhesion of dirt (antifouling property). However, the imparting of antifouling property to the keratin substance has not been examined in PTL 1.
The present invention relates to a method for treating an artificially colored or decolored keratin substance or fiber for a head decoration product, in which the color durability of the keratin substance or the fiber for a head decoration product can be improved even by a single treatment, and an effect of preventing adhesion of dirt can be imparted.
The present inventors have found that the above-described problems can be solved by treating an artificially colored or decolored keratin substance or fiber for a head decoration product with a composition containing a silicone film-forming agent and organopolysiloxane having a degree of polymerization of 100 or more at a predetermined mass ratio, thereby completing the present invention.
According to the present invention, it is possible to improve the color durability of a keratin substance or a fiber for a head decoration product which has been artificially colored or decolored even by one time treatment, and it is also possible to impart an effect of preventing adhesion of dirt.
“Polymer” as used herein means a compound corresponding to a repetition of one or plural units (these units are derived from a compound known as a monomer). This or these units are repeated at least two times preferably at least three times.
“Keratin substance” as used herein includes, for example, the skin, eyebrows, eyelashes, hair, and nails of an animal such as a human being, as well as artificially produced keratin substances (excluding fibers for a head decoration product).
“Hair” as used herein means human head hair, but also includes hair that has been cut from a human head.
“Head decoration product” as used herein means, for example, a hair wig, a wig, weaving, hair extension, a blade hair, a hair accessory, and a doll hair.
“Fiber for a head decoration product” as used herein means a fiber used in the head decoration product.
“Hydrophobic” as used herein means that a solubility in water of a substance is less than 1% by mass at 25° C.
“Film formation” as used herein means that, when applied to a substrate, a solid film is left thereon.
“Volatile” as used herein means a substance having a boiling point of 260° C. or lower under normal pressure.
The method for treating a keratin substance or a fiber for a head decoration product of the present invention (hereinafter also referred to as the “present method”) is a method for treating an artificially colored or decolored keratin substance or fiber for a head decoration product with a composition, and the method includes a step of applying the composition to the keratin substance or the fiber for a head decoration product, in which the composition contains the following component (A) and component (B): (A) a silicone film-forming agent; (B) an organopolysiloxane having a degree of polymerization of 100 or more, and in which a proportion of a content mass of the component (A) to a total content mass of the component (A) and the component (B) [(A)/{(A)+(B)}] is 10% or more.
According to the above-mentioned constitution of the present invention, it is possible to improve the color durability of a keratin substance or a fiber for a head decoration product which has been artificially colored or decolored even by one time treatment, and it is also possible to impart an effect of preventing adhesion of dirt. That is, the method of the present invention relates to a method for protecting the color of an artificially colored or decolored keratin substance or fiber for a head decoration product, and a method for imparting an effect of preventing adhesion of dirt to an artificially colored or decolored keratin substance or fiber for a head decoration product.
The term “one time treatment” as used herein means that the number of applications of the composition is one. However, in the method of the present invention, the artificially colored or decolored keratin substance or fiber for a head decoration product is not limited to being treated only once, and the treatment may be performed a plurality of times.
The reason why the present invention exhibits the above-mentioned effects is not clear, but is presumed as follows.
The composition used in the treatment method of the present invention can form a hydrophobic film on the surface of an artificially colored or decolored keratin substance or fiber for a head decoration product by containing the component (A) and the component (B). The component (A) is a hydrophobic film-forming agent, and since the strength and durability of the film can be maintained, it is considered that the color change of the keratin substance or the fiber for ahead decoration product due to friction or washing can be suppressed. On the other hand, it is considered that a large amount of the component (B) is present on the film surface side (air side) in the film to be formed, and it is considered that by having a degree of polymerization of a predetermined value or more, the component (B) can perform a surface protective function for a keratin substance or a fiber for a head decoration product and can impart an effect of preventing adhesion of dirt. Since the component (A) and the component (B) have compatibility, it is considered that when the component (A) and the component (B) are applied to the surface of an artificially colored or decolored keratin substance or fiber for a head decoration product due to a synergistic effect thereof, the color durability can be improved and an effect of preventing adhesion of dirt can also be imparted.
In addition, it is considered that in a case where the proportion of a content mass of the component (A) to a total content mass of the component (A) and the component (B) [(A)/{(A)+(B)}] is 10% or more, a film having higher durability against washing can be formed. Therefore, it is considered that the color durability and the effect of preventing adhesion of dirt of the artificially colored or decolored keratin substance or fiber for a head decoration product are obtained even by one time treatment.
It should be noted that the action mechanism of the present invention is not limited to the above.
The keratin substance to which the method of the present invention is applied preferably includes skin, eyebrows, eyelashes, hair, and nails. From the viewpoint of the effect of improving color durability, among these, skin, eyebrows, eyelashes, or hair is more preferable, and hair is still more preferable.
The fiber for a head decoration product to which the method of the present invention is applied may be either a naturally derived fiber or a synthetic fiber, and a naturally derived fiber is preferable. The naturally derived fiber refers to a fiber collected from a natural animal or plant (excluding human hair) or a fiber artificially produced using a protein or a polysaccharide as a raw material. Of these, fibers artificially produced from animal hair or proteins or polysaccharides such as proteins derived from keratin, collagen, casein, soybean, peanut, corn, and silk are preferable, regenerated protein fibers from keratin, collagen, casein, soybean protein, peanut protein, corn protein, and silk protein (for example, silk fibroin) are more preferable, regenerated protein fibers such as regenerated collagen fibers from collagen and regenerated silk fibers from silk fibroin are more preferable, and regenerated collagen fibers are still more preferable.

Hereinafter, the present invention will be described with reference to Examples, but the present invention is not limited to the scope of Examples. In these Examples, various measurements and evaluations were performed by the following methods.
A bundle of human gray hair (100%) (manufactured by Beaulax Corporation, length: 10 cm, mass: 1 g) was washed with a plain shampoo having the following composition, rinsed with warm water at 40° C., and sufficiently dried. To this hair bundle, 0.30 g of a hair dye composition (isododecane dispersion of carbon black (1% by mass)) having the following composition was applied, and then dried with a dryer (artificial coloring). Further, 0.20 g of the hair cosmetic composition of each example was applied, and then dried with a dryer to perform hair treatment.
After the treated hair bundle was subjected to colorimetry using a D65 light source of a color difference meter (CR-400, manufactured by Konica Minolta, Inc.) in the CIE color system (L*, a*, b*), the hair bundle was washed with a plain shampoo having the above-described composition using warm water at 40° C., and dried, and this process was performed seven times. The hair bundle after being washed and dried seven times was similarly color-measured by a color difference meter, and the color difference (ΔE*) from the hair bundle before being washed was calculated according to the following equation. The measurement of L, a*, and b* was performed at six different points on the hair bundle (one point on each of the front and back sides of the central portion of each region obtained by dividing the hair bundle into three equal parts in the length direction), and the average value was calculated.
When ΔE* <17, it can be determined that the hair bundle after treatment has good hair washing resistance and excellent color durability. Further, when ΔE* <15, it is better, when ΔE* <10, it is further better, and when ΔE* <5, it is still further better.
20 μL of the hair cosmetic composition of each example was added dropwise to a commercially available PET film (Lumirror Film T60-A4-100 μm, manufactured by Toray Industries, Inc.), stretched with a bar coater (No. 3, manufactured by AS ONE Corporation), and air-dried to form a coating film, and then the coating film-formed portion was cut out to a size of 3 cm×3 cm to prepare a test film. The mass of this film is defined as F0 [g].
As a model of physical contamination, zirconia beads (“YTZ balls” manufactured by Nikkato Corporation, φ=1 mm) were used. 10.4 g of zirconia beads were placed in a balance dish (BD-2, manufactured by AS ONE Corporation) and leveled, and the coating film surface of the film cut into a size of 3 cm×3 cm was brought into contact therewith. Next, a balance dish was placed on the film, and a weight, which was obtained by adding tap water to a standard bottle (No. 11, manufactured by AS ONE Corporation) and setting the weight to 200 g, was placed on the balance dish for 30 seconds. Then, the weight was removed, and the mass (F1 [g]) of the film to which the beads were attached was measured.
From the change in mass of the film before and after the contact with the beads, the adhesion rate of the beads was calculated by the following formula. As the mass of the beads covering the area of the test film of 3 cm×3 cm by 100%, 2.68 g (average value of two measurements) was used.
The above test was performed twice, and the average value was shown in the table. It can be said that when the adhesion rate is 25% or less, dirt is difficult to adhere, when the adhesion rate is 20% or less, dirt is more difficult to adhere, when the adhesion rate is 15% or less, dirt is still more difficult to adhere, and when the adhesion rate is 5% or less, dirt is even more difficult to adhere.
Examples 1 to 19 and Comparative Examples 1 to 3 (Preparation and Evaluation of Hair Cosmetic Composition) Each of the components shown in Tables 1 to 4 was blended at the blending ratio described in each table, and mixed until homogeneous to prepare a hair cosmetic composition. Using the obtained hair cosmetic composition, evaluation was performed by the method described above. The results are shown in Tables 1 to 4.
The blending amounts (00 by mass) described in the tables are all amounts of active ingredients.
A bundle of artificial hair having a length of 10 cm, a width of 1.5 cm, and a mass of 1 g was produced using a regenerated collagen fiber “Nextension Crystal XXL 30” (color number: 30 (white), shape: straight) manufactured by Kaneka Corporation as a fiber for a head decoration product.
Artificial coloring and hair treatment were performed in the same manner as in Example 1 except that the above-described artificial hair bundle was used in place of the human gray hair (100%) bundle in Example 1, and the above-described evaluation was performed. The results are shown in Table 5.
The ingredients shown in the tables are as follows.
Regarding the degree of polymerization (P) of the above-mentioned components *2 and *5 to *11, the molecular weight (M) is obtained from the above-mentioned formula (4) from the viscosity (η), and the degree of polymerization (P) can be obtained from the following formula (5) since the molecular weight of the basic unit of dimethylpolysiloxane is 74.
From Tables 1 to 4, according to the treatment method of the present invention, by performing one time treatment, color fading is reduced even after artificially colored hair is repeatedly washed, and color durability is good. In addition, it can be seen that an effect of preventing adhesion of dirt to hair can be imparted. In Comparative Example 1, a smooth film was not formed, and the evaluation of “Difficulty in Adhesion of Dirt” could not be performed.
In addition, from Table 5, it can be seen that according to the treatment method of the present invention, even in a case where regenerated collagen fibers which are fibers for head decoration products are used in place of hair, good color durability and an effect of preventing adhesion of dirt can be obtained.
According to the present invention, it is possible to improve the color durability of a keratin substance or a fiber for a head decoration product which has been artificially colored or decolored even by one time treatment, and it is also possible to impart an effect of preventing adhesion of dirt.
