Description

Technical Field

[0001] The present invention relates to a temporary hair dye composition.

Background Art

[0002] In recent years, due to the increasing demand for gray hair dyeing among the aging population and the fashionability of colored hair, hair dyes have become popular. Hair dyes are classified into temporary hair dyes, semi-permanent hair dyes, and permanent hair dyes from the perspective of the durability of the color applied to the hair. Among these, temporary hair dyes have the advantage that their usage method is simple and they only need to be applied to the target area, enabling quick hair dyeing, and are optimal for use before going out. In addition, temporary hair dyes can be easily washed off with shampoo, so they are convenient when there is dissatisfaction with the dyed color or when wanting to change to another color, and the demand for them in the market is also high.

[0003] Conventionally, a spray product in which a composition containing a coloring material centered on an inorganic pigment, a film-forming agent for fixing the coloring material to the hair and preventing secondary adhesion to clothes, etc., and a quick-drying volatile solvent such as ethanol is filled in an aerosol can together with an aerosol spraying agent is known (see, for example, Patent Document 1).

[0004] In the above temporary hair dye, a polymer compound having film-forming properties is used as the film-forming agent, and the colored hair tends to feel stiff. In order to reduce such a stiff feeling, temporary hair dyes blended with a gelling agent or an oily substance have also been proposed (see, for example, Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, with the conventional technology described above, it was difficult to adequately prevent secondary adhesion of colorants.

[0007] The present invention aims to provide a temporary hair dye composition that can color hair with a finish that does not feel stiff, and that can sufficiently prevent secondary adhesion. [Means for solving the problem]

[0008] To solve the above problems, the present invention provides a temporary hair dye composition containing (A) a soap base and (B) a pigment.

[0009] The temporary hair dye composition of the present invention, having the above-described structure, can color hair with a finish that does not feel stiff, and can also sufficiently prevent secondary adhesion. The inventors surmise that the reason why the present invention achieves these effects is that the inclusion of a soap base simultaneously provides the property of fixing the pigment to the hair and the property of reducing frictional resistance in the hair to which the pigment has been fixed, thereby efficiently improving resistance to secondary adhesion.

[0010] The temporary hair dye composition of the present invention may have a moisture content of 20% or less as measured by the Karl Fischer method.

[0011] The temporary hair dye composition of the present invention may be in powder or solid form.

[0012] The content of component (A) above may be 30 to 90% by mass, based on the total amount of the temporary hair dye composition.

[0013] The mass ratio (A) / (B) of the content of component (A) above to the content of component (B) above may be 0.5 to 80.

[0014] The temporary hair dye composition of the present invention comprises (B1) a coloring pigment and (B2) an extender pigment as component (B), and when the total content of component (A), component (B1), and component (B2) is 100 parts by mass, the content of component (B1) may be 0.5 to 50 parts by mass, and the content of component (B2) may be 0.5 to 50 parts by mass.

[0015] The total amount of component (B1) and component (B2) described above may be 1 to 55 parts by mass.

[0016] The temporary hair dye composition of the present invention may further contain a nonionic surfactant.

[0017] The temporary hair dye composition of the present invention can be used by mixing it with water. [Effects of the Invention]

[0018] According to the present invention, it is possible to provide a temporary hair dye composition that can color hair with a finish that does not feel stiff, and that can sufficiently prevent secondary adhesion. [Modes for carrying out the invention]

[0019] [Temporary hair dye composition] The temporary hair dye composition of this embodiment contains (A) a soap base (hereinafter sometimes referred to as component (A)) and (B) a pigment (hereinafter sometimes referred to as component (B)).

[0020] <(A) Soap base> As the soap base, known soap bases used in cosmetics can be used. For example, animal fats such as beef tallow and mutton fat, or vegetable fats such as coconut oil, palm oil, palm kernel oil, soybean oil, olive oil, cottonseed oil, or mixed fats thereof are saponified with an alkaline aqueous solution such as an aqueous solution of caustic soda or an aqueous solution of caustic potash, or fatty acids obtained by decomposing these fats are neutralized with an alkaline aqueous solution such as an aqueous solution of caustic soda, an aqueous solution of caustic potash, an aqueous solution of alkanolamine, etc. What is prepared by this can be used, and it may be formulated in the neat soap state, or the dried one may be formulated.

[0021] The soap base can contain fatty acid salts having 10 to 40 carbon atoms, and may contain fatty acid salts derived from plants such as palm kernel fatty acid salts, palm fatty acid salts, hydrogenated coconut fatty acid salts, sunflower seed oil fatty salts, etc., and may contain higher fatty acid salts such as myristate, stearate, isostearate, etc. These salts may be alkali salts such as sodium salts and potassium salts, amino acid salts such as aspartate and arginine salts, or amine salts such as triethanolamine salts. Also, the soap base may contain solid soap, liquid soap, or both. Furthermore, the soap base may contain a pH adjuster such as citric acid and sodium hydroxide. In the component display of the soap base, when the display name of the fatty acid salt is described separately as the fatty acid and the alkali that neutralizes it, or the display name of the plant-derived fatty acid may be described as, for example, sunflower seed oil fatty acid as sunflower seed oil.

[0022] The soap base may contain water or may not contain water. The water content in the soap base may be 0.1 to 80% by mass, may be 0.5 to 20% by mass, or may be 1.0 to 18% by mass. In this specification, the water content means a value measured by the Karl Fischer method.

[0023] The content of the fatty acid salt in the soap base may be 20 to 100% by mass based on the total amount of the soap base from the viewpoint of the fixing property of the pigment, may be 60 to 95% by mass from the viewpoint of achieving both the fixing property of the pigment and the resistance to secondary adhesion, and may be 70 to 90% by mass.

[0024] In addition, the content of the fatty acid salt can be measured in accordance with "JIS K3304:2019 (6.4 Pure Soap Content)".

[0027] Also, in this embodiment, the blending amount of the component (A) may be set using the content of the fatty acid salt contained in the component (A) as an index (in other words, in terms of the mass conversion of the fatty acid salt). In this case, the blending amount of the component (A) may be 20 to 90% by mass, 30 to 80% by mass, or 35 to 75% by mass based on the total amount of the temporary hair dye composition in terms of the mass conversion of the fatty acid salt. That is, the content of the fatty acid salt derived from the component (A) in the temporary hair dye composition may be within the above numerical range.

[0037] The temporary hair dye composition of this embodiment may contain (B1) a coloring pigment and (B2) an extender pigment as component (B). In this case, the content of component (B1) and the content of component (B2) may be 0.5 to 50 parts by mass and 0.5 to 50 parts by mass, 1.0 to 45 parts by mass and 20 to 50 parts by mass, or 1.0 to 35 parts by mass and 20 to 40 parts by mass, respectively, when the total content of components (A), (B1), and (B2) is 100 parts by mass.

[0038] Furthermore, from the viewpoint of smooth usability and resistance to secondary adhesion, when the total content of component (A), component (B1), and component (B2) is 100 parts by mass, the total content of component (B1) and component (B2) may be 1 to 55 parts by mass, 5 to 45 parts by mass, or 10 to 40 parts by mass.

[0046] From the perspective of affinity with the soap base, a nonionic surfactant with an HLB value of 8.0 or higher can be used. The HLB (hydrophilic-lipophilic balance) is calculated using the following formula based on the Griffin method. HLB value = 20 × [(Sum of molecular weights of hydrophilic parts) / (Total molecular weight)]

[0054] The shape of the solid temporary hair dye composition may be circular, elliptical, polygonal, rectangular, star-shaped, heart-shaped, flower-shaped, or the like.

[0055] If the temporary hair dye composition is a molded body, the hardness at 25°C measured by a rheometer (measurement conditions: tip shape of pressure-sensitive shaft is a rod with a diameter of 1 mm, needle insertion speed is 6 cm / min, needle insertion depth is 2 mm) may be 0.1 N or higher, or it may be 1 to 15 N.

[0056] The temporary hair dye composition of this embodiment can be used by mixing it with water. For example, the temporary hair dye composition can be mixed with water, and the resulting foam can be applied to the hair. In this case, the temporary hair dye composition may be in solid or powder form, the water content may be within the range described above, and it may be in granule, sheet or molded form, from the viewpoint of foaming and ease of use. Also, from the viewpoint of color development, 5 parts by mass or more, 10 to 70 parts by mass, or 20 to 60 parts by mass of water may be mixed with 100 parts by mass of the temporary hair dye composition.

[0057] Tools for whipping include brushes, sponges, combs, screw brushes, and spatulas.

[0058] The temporary hair dye composition of this embodiment can be used for temporary hair dyeing of hair, eyebrows, etc., and may also have functions such as hair styling, treatment, and eyebrow styling.

In this case, the moisture content of the powder may be within the range described above.

[0062] (In the case of a molded body) The base material obtained above can be filled into a predetermined container and compressed or heated and melted as necessary to produce a molded body of a temporary hair dye composition in a predetermined shape (e.g., a compression molded body, a melted molded body, or an extruded molded body). Alternatively, the base material obtained above can be heated and melted, filled into a predetermined container, and solidified to produce a molded body of a temporary hair dye composition in a predetermined shape (e.g., a filled molded body). The molded body may have a moisture content within the range described above, and its hardness may also be within the range described above.

[0063] (In the case of granules) The base material obtained above can be converted into granules by methods such as dry granulation or wet granulation to produce granules of a temporary hair dye composition. In this case, the moisture content of the granules may be within the range described above.

[0064] (In the case of a sheet) The base material obtained above can be formed into a sheet by stretching or casting to produce a sheet of temporary hair dye composition. In this case, the moisture content in the sheet may be within the range described above.
