Description

[Technical Field]

[0001] The present invention relates to an aerosol type hair coloring composition. [Background technology]

[0002] Conventionally, in order to obtain a hair-thinning effect in areas where hair appears thin due to hair loss or thinning of individual hairs, there have been methods such as actually implanting or attaching natural or artificial hair. However, such methods require treatment by a professional, and are extremely inconvenient as they require a great deal of time and money.

[0003] In recent years, in order to solve the problems of hair thinning and graying associated with aging, hair colorants have been widely used to give hair a feeling of thickened hair and conceal gray hair by coloring it. Such hair colorants mainly include those in which colored fibers are sprinkled on the hair and then fixed with a setting agent, and those in which an aerosol spray containing a pigment is applied to the hair. However, these hair colorants have problems such as the color of the colored area not blending with the original hair color, resulting in an unnatural finish, and the color of the hair only changing, without actually achieving a feeling of thickened hair. Furthermore, those in which colored fibers are sprinkled on the hair and then fixed with a setting agent require time and skill and are hardly convenient.

[0004] Patent Document 1 proposes an aerosol-type hair-thickening coloring hair dye containing a powder carrier such as talc, a colorant such as carbon black, and a setting agent such as resin, in order to more effectively improve the feeling of thickened hair. This is an aerosol-type hair-thickening coloring hair dye that uses a method in which a powder carrier made of talc or the like carrying a colorant such as carbon black is attached to each individual hair strand, which is then coated with a setting agent such as resin, making each individual hair appear thicker, thereby achieving the feeling of thickened hair.

[0005] On the other hand, Patent Document 2 proposes a spray composition for thinning hair that gives hair a thickened appearance by using bamboo charcoal particles having a predetermined particle size as a colorant, without using a powder carrier such as talc. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 08-143434 [Patent Document 2] Japanese Patent Application Laid-Open No. 2005-075745 Summary of the Invention [Problem to be solved by the invention]

[0007] In Patent Document 1, when a powder carrier such as talc is used in large quantities to effectively impart a thickened hair feel, the white or gray color of the powder carrier itself interferes with the color of the colorant such as carbon black, resulting in an unnatural finish because the colored area does not blend with the original hair color. On the other hand, if the content of the powder carrier such as talc is reduced to prevent interference due to the color of the powder carrier, a satisfactory thickened hair feel cannot be obtained. Furthermore, a setting agent such as a resin is used to fix the powder carrier such as talc to the hair, causing the hair to feel wet immediately after spraying the spray onto the hair, and it takes time for the hair to dry completely, resulting in a lack of quick-drying properties. However, setting power is necessary to fix the powder carrier to the hair, and there was room for consideration of setting agents.

[0008] On the other hand, the hair thinning spray composition of Patent Document 2 had a problem in that the bamboo charcoal particles tended to settle and form lumps. This further led to poor redispersibility, and there was concern that when the bamboo charcoal particles entered the spray nozzle, clogging and other spraying problems would easily occur.

[0009] Therefore, an object of the present invention is to provide an aerosol type hair coloring composition that has a thickening effect, good color compatibility and redispersibility, is free from clogging, and has excellent setting power and quick-drying properties. [Means for solving the problem]

[0010] As a result of extensive research, the present inventors have found that The following components (A) to (F) (A) one or more selected from octenyl succinic acid corn starch ester aluminum, talc, and cellulose (B) Charcoal (C) Polyoxyethylene alkyl ether phosphate or its salt (D) Amphoteric polymer resin compound (E) Ethanol The content of the component (B) is 0.5 to 5% by mass, and the content of purified water is 5% by mass or less. The inventors have found that an aerosol type hair coloring composition containing an aerosol concentrate (a) and (F) liquefied petroleum gas as a propellant can solve the above problems, and have completed the present invention.
