  The foam of the aerosol foam hair dye composition can behave in various ways. For example, when applied to hair, there were a type that quickly defoamed and a type that increased in bulk during the operation of applying foam to the entire hair. Conventionally, dyeing unevenness has often occurred in aerosol type foamed hair dye compositions. In addition, there were often cases of insufficient hair dyeing.

  The aerosol foamed oxidative hair dye composition can be obtained by dividing fine foam into a plurality of times. It is an advantage of the aerosol-type foamy oxidative hair dye composition that it can be used in a plurality of times. However, normally, the contents of the aerosol container cannot be visually observed, and it is difficult to accurately grasp the weight of the discharged foam by hand. When it is applied to hair by being discharged from an aerosol container divided into a plurality of times, it is even more difficult to accurately grasp the total weight and total volume of the applied foam by hand.

  Also, oxidation dyes are often colorless before color development, and if the bubbles disappear during the coating operation, it is difficult to know how far the coating operation has been completed and how much foam has been applied. This was one of the causes of uneven dyeing.

  Even when the volume of the foam and the foam is increased during the coating operation, it may be difficult to know how much foam is applied on the hair later. In this case, even if the weight of the applied foam is constant, the bulk of the foam is increased later, so that the total weight of the foam often results in insufficient hair dyeing. Also, the bulk of the foam could not be increased uniformly, and dyeing unevenness often occurred.

  From the above, the inventor of the present application has focused on the point that the user of the aerosol-type foamy oxidative hair dye composition “determines that appropriate application has been made by visually observing the state of bubbles on the hair”.

  Conventional aerosol-type oxidative hair dye compositions are applied to the hair to defoam, while the bulk of the foam is increased during the application operation. Therefore, there was a difference between the weight of the foam visually recognized and the weight of the foam actually applied to the hair.

  As a result of intensive studies, the inventor of the present application has found that an aerosol-type foamy oxidative hair dye composition can be used as perceived by the user's eyes by suppressing changes in the specific gravity of foam over time. That is, the present inventors have found that there is an appropriate range in which the user's recognition and hair dyeing effect are tuned, and the volume of bubbles does not increase or decrease too much.

  It is an object of the present application to provide an aerosol type oxidative hair dye composition which is excellent in leveling property, hair dyeing power and operability, and which suppresses dripping well.

[Propellant]
A well-known propellant can be used for the aerosol-type foam oxidation hair dye composition which this application discloses. For example, liquefied gas such as LPG and dimethyl ether, and compressed gas such as carbon dioxide gas and nitrogen gas can be exemplified. Among these, liquefied gas is preferable. These 1 type (s) or 2 or more types can be used.

  The filling ratio of each agent and propellant constituting the aerosol foamed oxidative hair dye composition contained in the aerosol container is preferably 90:10 to 98: 2 by mass ratio, and 92: 8 to 97: 3 is more preferable. Moreover, it is also preferable to set the mixing ratio of any one of the plurality of agents to 92: 8 to 97: 3.

  When each agent constituting the aerosol foamed hair oxide composition such as the first agent and the second agent is an emulsion, each agent is a stock solution stage that does not contain a propellant in view of the manufacturing process. And even after filling with the propellant. That is, if it is an emulsion after filling with a propellant, it can be reasonably estimated that the stock solution corresponding to each agent was also an emulsion.

〔blend〕
The mixing ratio of a plurality of agents including the first agent and the second agent can be determined as appropriate. The mixing ratio of the first agent and the second agent is preferably first agent: second agent = 1: 5 to 5: 1.

  It is preferable that pH of the mixture of each agent which comprises an aerosol type | formula foaming hair dye composition is 7-12.

  The foam specific gravity is obtained by dividing the mass of the foam by the volume at 25 ° C. The unit is g / ml. The “foam specific gravity at 5 minutes after mixing” can be determined from the collected bubbles after mixing a plurality of agents, applying the mixture to the hair for 5 minutes, collecting bubbles remaining on the hair after 5 minutes. The specific operation of the measurement of the initial foam specific gravity and the measurement of the foam specific gravity at 5 minutes after mixing can refer to “measurement of foam specific gravity” in Examples described later.

  The initial foam specific gravity (that is, foam specific gravity immediately after preparation of the mixture and before application to the hair), which is the foam specific gravity immediately after the mixing of each agent constituting the aerosol foamed hair dye composition, is 0.03 to 0.3. 18. Outside this range, “easy to apply”, “little dripping”, “leveling” and “hair dye” cannot be improved in a balanced manner. If the initial foam specific gravity is less than 0.03, the bulk of the foam is too large and the total amount of the mixture applied to the hair is insufficient. In this case, in particular, evaluation of “ease of application” and “hair dyeing power” is insufficient. If the initial foam specific gravity exceeds 0.18, the foam volume is too small. In this case, in particular, the evaluation of “ease of application” is insufficient.

  Initial bubble specific gravity becomes like this. Preferably it is 0.04-0.16, More preferably, it is 0.05-0.15, More preferably, it is 0.05-0.10. Within these preferred ranges, “easy to apply”, “little dripping”, “level dyeing” and “hair dyeing power” are improved in a well-balanced manner.

  The foam specific gravity change rate (%) obtained from the foam specific gravity at 5 minutes after mixing and the initial foam specific gravity (%) is obtained by “(bubble specific gravity at 5 minutes after mixing ÷ initial bubble specific gravity) × 100”. The aerosol foam oxidation hair dye composition disclosed in the present application has a foam specific gravity change rate of 100% to 150%. If the foam specific gravity change rate is out of the range, the evaluations of “less dripping”, “level dyeability” and “hair dyeing power” are not improved in a well-balanced manner. The foam specific gravity change rate is preferably 105 to 145%, more preferably 110 to 140%. Within these preferred ranges, “easy to apply”, “little dripping”, “level dyeing” and “hair dyeing power” are improved in a well-balanced manner.

  Hereinafter, preferable conditions in the mixture will be further described. In the following description, a preferable blending amount is described assuming that the total amount of the mixture is 100% by mass. The compounding quantity of the specific component in a mixture is demonstrated by the compounding quantity in the composition which does not contain a propellant as above-mentioned. Each agent constituting the aerosol foamed hair dye composition is usually accommodated separately. Therefore, it is also possible to calculate the blending amount of a specific component in the mixture from the blending amount in each agent and the mixing ratio of each agent.

  The blending amount of the oil component in the mixture is preferably 15% by mass or less. More preferably, it is 0.01-10 mass%, More preferably, it is 0.05-8 mass%, More preferably, it is 0.1-6 mass%. Within these preferred ranges, the bubbles are likely to remain without defoaming. In addition, “less dripping” and “level dyeability” are improved in a well-balanced manner. Moreover, the provision of moisture and gloss are improved by blending the oil component.

  The components corresponding to the oil component and the preferred components are the same as the above-mentioned “preferred conditions for each agent constituting the aerosol-type foam hair dye composition”. The same applies to components corresponding to surfactants and higher alcohols and preferred components.

  It is preferable that the compounding quantity of the ionic surfactant in a mixture is 0.01-6 mass%. More preferably, it is 0.05-5 mass%, More preferably, it is 0.1-4 mass%, More preferably, it is 0.1-3 mass%. Within these preferable ranges, “easiness of application”, “leveling property” and “hair dyeing power” are improved in a balanced manner.

  It is preferable that the compounding quantity of the higher alcohol in a mixture is 0.5-5 mass%. More preferably, it is 0.5-3 mass%. Within these preferable ranges, there is an advantage that both improvement in hair dyeing power and improvement in foam quality can be achieved.

  Furthermore, the mixture preferably contains behenyl alcohol, which is a higher alcohol. By blending behenyl alcohol, the foam quality is good and the foam tends to remain. In addition, since the foam quality is tight, there is an advantage that it is difficult to sag and the foam is easy to stretch. The preferable compounding quantity of behenyl alcohol in a mixture is 0.01-2 mass%.

  In the mixture, attention is focused on higher alcohols that are solid at 25 ° C. and 1 atm (hereinafter sometimes abbreviated as “solid higher alcohols”) among the higher alcohols. Examples of higher alcohols that are solid at 25 ° C. and 1 atm include cetyl alcohol (cetanol), cetostearyl alcohol, stearyl alcohol, aralkyl alcohol, and behenyl alcohol.

  From the viewpoint of improvement of foamability and change rate of foam specific gravity, the mass ratio of the ionic surfactant to the solid higher alcohol in the mixture “ionic surfactant / solid higher alcohol” = 0 to 3 is preferable. More preferably, it is 0.05-2.8, More preferably, it is 0.2-2.5, More preferably, it is 0.3-2.0.

  For convenience of expressing the ratio, even when the blending amount of the solid higher alcohol in the mixture is 0, it is expressed as “ionic surfactant / solid higher alcohol = 0”.

The agent composition is excellent in operability, can suppress dyeing unevenness, and provides a hair dyeing effect that is visually recognized by the user.

[Aerosol container]
The aerosol-type foamy oxidative hair dye composition which this application discloses can be accommodated in a known aerosol container. Since it is necessary to mix the 1st agent which mix | blends an alkaline agent and the 2nd agent which mix | blends an oxidizing agent immediately before use, a 1st agent and a 2nd agent are normally accommodated separately. The first agent and the second agent may be accommodated in separate aerosol containers. When discharged by the force of the propellant, the propellant expands to form bubbles.

The relationship between foam specific gravity and visual observation will be described using the following test photographs.
[Test photo]

  The upper part of the test photograph is a photograph of a test in which a mixture having a foam specific gravity change rate of 100 to 150% was applied. The middle row is a photograph of a test in which a mixture having a foam specific gravity change rate exceeding 150% (antifoam formulation) was applied. The lower row is a photograph of a test in which a mixture having a foam specific gravity change rate of less than 100% (foam increase formulation) was applied.

  The “appropriate application” in the left column of the test photograph is the hair after applying a sufficient amount of the mixture over a period of 5 minutes. The center column “foam state at the time of mixing” indicates the state of the foam immediately after mixing the first agent and the second agent. In the right column “foam state after application”, the foam remaining on the hair after being applied for 5 minutes was collected and photographed.

  In the mixture having a foam specific gravity change rate of 100 to 150%, the bulk of the foam during the application operation was kept within a certain range, and the mixture could be applied uniformly to the entire hair bundle. In the mixture of the foam increasing formulation and the defoaming formulation, the volume of the foam increased or decreased during the coating operation, leaving a trace of hand handling. In addition, it was difficult to prepare bubbles at the root and tip of the hair bundle during the coating operation.

  Although not shown in the photograph, the mixture of Comparative Example 1 had a large volume of bubbles and required a small amount of weight because it seemed to be properly applied visually. On the other hand, the mixture of Comparative Example 2 had a small amount of foam and required a large amount of weight because it was considered that the mixture was properly applied visually.

  In the above test, the change rate of the foam specific gravity was obtained from (i) the initial foam specific gravity of the foam before being applied to the hair, and (ii) the foam specific gravity obtained from the foam collected after the application operation to the hair. It was. There was a correlation between the foam specific gravity change rate and the good effect. Therefore, in particular, it was considered that the foam specific gravity at 5 minutes after mixing would be sufficient if obtained from the foam collected from the hair subjected to the application operation.
