Description

Technical Field

[0001] The present invention relates to temporary hair dyes. Background Art

[0002] Hair dyes can be classified into temporary hair dyes, semi-permanent hair dyes, and permanent hair dyes according to the persistence of the color of hair coloring. Semi-permanent hair dyes and permanent hair dyes have the advantage of being difficult to fade even when rinsed with shampoo, but they also have the aspect that the operation becomes complicated until the hair dyeing is completed. On the other hand, temporary hair dyes have the advantages of simple use methods, only need to be applied to the target area, and can dye hair quickly, which is most suitable for use before going out. In addition, since temporary hair dyes can be easily washed off with shampoo, they are convenient when the dyed color is not satisfactory or when you want to change to another color, and the market demand for them is also high.

[0003] In the past, temporary hair dyes were composed of color materials centered on inorganic pigments with high covering properties such as carbon black and titanium black, film-forming agents for fixing and attaching the color materials to hair and preventing secondary contamination of clothes, and volatile solvents with quick-drying properties such as ethanol. In recent years, research has also been carried out to improve the usability and feel of temporary hair dyes. For example, in Japanese Patent Laid-Open No. 10-265354, for the purpose of improving the secondary adhesion and color persistence after coating, a hair dye containing a volatile oil component, a hydrophobic polymer dissolved in the volatile oil component, a powder containing a coloring pigment, and a non-volatile oil component compatible with the volatile oil component was proposed. In addition, in Japanese Patent Laid-Open No. 11-49651, from the viewpoints of abrasion resistance, non-sticky or hard feel, and non-color uneven hair dyeing, a temporary hair dye in which a specific pigment, a gelling agent, and a film-forming polymer are blended in a specific ratio was proposed. Summary of the Invention

[0004] However, the pigment dispersibility of the temporary hair dye described in the above Patent Document 1 is insufficient, and color unevenness is likely to occur. In addition, the temporary hair dye described in the above Patent Document 2 cannot fully meet the requirements in terms of balancing quick-drying properties, abrasion resistance, and non-hard feel.

[0005] The present invention has been completed in view of the above circumstances, and an object thereof is to provide a temporary hair dye that has sufficient quick-drying properties, enables sufficient reduction of color unevenness and hard feeling, and also has excellent abrasion resistance.

[0006] To solve the above problems, the following invention is provided.

[0007] [1]A temporary hair dye, which is a temporary hair dye containing (A) a coloring material. The above temporary hair dye further contains (B) an alcohol having 1 to 3 carbon atoms, (C) a hydrophilic powder (however, excluding the above coloring material), (D) at least one compound that is liquid at 25°C selected from the group consisting of alcohols having a hydrocarbon group with 4 to 24 carbon atoms and their derivatives, and fatty acids having 8 to 24 carbon atoms and their derivatives, and (E) a water-soluble film-forming agent. The content of the above (B) component is 10 to 90% by mass based on the total amount of the temporary hair dye. [2]The temporary hair dye according to [1], wherein the ratio (B) / [(A)+(C)] of the content of the above (B) component to the total content of the above (A) component and the above (C) component is 1 to 30. [3]The temporary hair dye according to [1] or [2], wherein the above hydrophilic powder is a spherical powder with an average particle size of 10 nm to 20 μm. [4]The temporary hair dye according to any one of [1] to [3], wherein the above (E) component contains 10% by mass or more of betaine polymers based on the total amount of the (E) component. [5]The temporary hair dye according to any one of [1] to [4], wherein the content of the above (D) component is 800 to 5000 parts by mass relative to 100 parts by mass of the above (C) component. [6]The temporary hair dye according to any one of [1] to [5], wherein when the above temporary hair dye is allowed to stand, a supernatant layer containing the above (B) component and a precipitate layer containing the above (A) component and the above (C) component are formed. [7]The temporary hair dye according to any one of [1] to [6], wherein the above (A) component contains a hydrophobic-treated coloring pigment. [8]The temporary hair dye according to [7], wherein the content of the hydrophobic-treated coloring pigment is 50% by mass or more based on the total amount of the above (A) component. [9]The temporary hair dye according to any one of [1] to [8], wherein the above (C) component is silica.

[10] The temporary hair dye according to any one of [1] to [9], wherein the content of the above (E) component is 50 to 1000 parts by mass relative to 100 parts by mass of the (A) component.

[0008] The temporary hair dye according to [1] above can achieve hair dyeing with sufficient quick-drying property, while sufficiently reducing color unevenness and stiffness and having excellent rub resistance. The inventors of the present invention speculate the reasons for achieving the above effects as follows. First, when using a conventional temporary hair dye containing a coloring material and a film-forming agent, it is considered that the main reason for the difficulty in suppressing secondary adhesion and stiffness is that if there is a large amount of coloring material on the surface of the film layer formed by the film-forming agent, it is easy to cause stiffness and staining due to unevenness. In particular, it can be expected that when the dispersibility of the coloring material in the hair dye is improved from the viewpoint of suppressing color unevenness, it is difficult to eliminate the above problems. In contrast, the inventors of the present invention believe that according to the temporary hair dye having the above composition, due to the characteristics of being able to sufficiently disperse the coloring material before coating and the hydrophilic powder having a high affinity and a large specific gravity with the hair precipitating on the hair together with the coloring material during coating and drying (a characteristic of deliberately making the coloring material easy to separate), it is possible to suppress the generation of color unevenness sufficiently while forming a film layer with suppressed generation of unevenness caused by the coloring material and having a highly smooth surface.

[0009] According to the present invention, it is possible to provide a temporary hair dye that can achieve hair dyeing with sufficient quick-drying property, while sufficiently reducing color unevenness and stiffness and having excellent rub resistance. Detailed Embodiments

[0041] From the viewpoint of balancing abrasion resistance and suppression of stiffness feeling, component (E) may contain two or more film formers with different hardnesses. The hardness of the film former can use the value measured by the following method. [Measurement of Hardness] Fill a screw tube with 20 g of a solution prepared so that the concentration of the film former is 30% by mass to obtain a measurement sample. After leaving the measurement sample in a constant temperature bath at 60 °C for 3 days, take it out of the constant temperature bath, cool it naturally to room temperature, and perform the following measurement. Using a rheometer (manufactured by Rheotech Co., Ltd.), measure the hardness (N) of the measurement sample under the conditions of the front end shape of the pressure-sensitive shaft: a rod-shaped cylinder with a diameter of 3 mm ( ), a penetration speed of 6 cm / minute, a penetration depth of 3 mm, and a temperature of 25 °C.

[0043] From the viewpoint of balancing friction resistance and suppression of a hardening feeling, the content of the (E) component can be 1 to 20% by mass, 1.5 to 15% by mass, or 3 to 12% by mass based on the total amount of the temporary hair dye.

[0044] From the viewpoint of friction resistance and separation of pigments, the content of the (E) component can be 50 to 1000 parts by mass, 100 to 500 parts by mass, or 150 to 400 parts by mass relative to 100 parts by mass of the (A) component.

[0045] For the temporary hair dye of the present embodiment, as components other than the above components (other components), components commonly used in cosmetics can be appropriately blended within a range not impairing the effects of the present invention. Examples of other components include thickeners, ultraviolet absorbers, preservatives, antioxidants, fragrances, surfactants, moisturizing components, dyes, oxidation dyes, antifoaming agents, salts, pH adjusters, reducing agents, alkalis, chelating agents, co-solvents, extracts, oil agents, and the like.

By blending the thickener, in addition to adjusting the viscosity of the temporary hair dye, the adhesiveness during coating can also be reduced.

[0047] The temporary hair dye of the present embodiment can form a supernatant layer containing the (B) component and a precipitate layer containing the (A) component and the above (C) component when left standing. Examples of the standing conditions include standing at 25°C for 2 hours. The (E) component may also be contained in the supernatant layer. By making the temporary hair dye have such separability, when coating the hair, during the volatilization of the (B) component, the (E) component is separated from the (A) component and the (C) component, and the (C) component preferentially adheres to the hair surface together with the (A) component, and it is easy to form a film-forming agent layer above it. Thereby, the abrasion resistance (resistance to secondary adhesion) can be improved.

[0048] From the viewpoint of the hair dyeing effect, the viscosity of the temporary hair dye of the present embodiment can be 1 to 1000 mPa·s, 2 to 900 mPa·s, or 10 to 800 mPa·s. It should be noted that the viscosity of the above temporary hair dye refers to the value (mPa·s) measured at a specified rotational speed at a temperature of 25 ± 1°C using a B-type viscometer with a rotor corresponding to the measurement adaptation range. Specifically, when the viscosity is 100 mPa·s or less, the viscosity of the temporary hair dye is measured using rotor No. 2 under the condition of a rotational speed of 60 rmp. When the viscosity is in the range of 100 to 2000 mPa·s, it is measured using rotor No. 2 under the condition of a rotational speed of 12 rmp. When the viscosity is in the range of 2000 to 8000 mPa·s, it is measured using rotor No. 3 under the condition of a rotational speed of 12 rmp.

[0049] The temporary hair dye of the present embodiment can be used, for example, with a brush, comb, or sponge to temporarily dye the parts that are concerned, such as the hairline. In addition, the temporary hair dye of the present embodiment can also be stirred, such as shaking the container before use, to mix the upper layer and the precipitate layer.

[0050] The temporary hair dye of the present invention can be prepared by combining the above components according to common methods. For example, the temporary hair dye can be obtained by mixing the above components (A) to (E) and, if necessary, mixing other components and stirring.

[0051] The above mixing / stirring can be carried out using an ordinary mixer, but if necessary, it can also be crushed and mixed using a homogenizer, ball mill, sand mill, roll mill, dispersion grinder, etc. In addition, the mixing / stirring is usually carried out at room temperature, but it can also be heated or cooled as needed.
