Description

  The present invention relates to an aerosol foam hair dye / bleaching agent composition and a hair dye / bleaching method using the same.

  2. Description of the Related Art Conventionally, foam-like ones are known as hair dye / bleaching agent compositions that dye hair (dye hair) or decolorize hair. This foamy hair dye / bleaching agent composition (hereinafter referred to as foamy hair dye / bleaching agent composition) is an aerosol-type discharge container (for example, aerosol type) containing a stock solution of the composition together with a propellant such as LPG. Used from a spray can).

  The stock solution of this composition is composed of a stock solution for the first agent containing an alkaline agent and an optional oxidation dye, and a stock solution for the second agent containing an oxidant, each of which is injected into a separate aerosol-type discharge container. Accommodated with. The discharge container is provided with a discharge head (simultaneous mixing / discharging mechanism) that simultaneously discharges foamy stock solution from each discharge container and mixes these foamy stock solutions.

  Thus, since a foam-like hair dye / bleaching agent composition is prepared in foam using an aerosol-type discharge container, it is also referred to as an aerosol-type hair dye / bleaching agent composition.

  As described above, the aerosol-type foamy hair dye / bleaching agent composition uses an aerosol-type discharge container for its preparation, so that it has good operability and is easy to use by dividing the required amount. In addition, the aerosol foam hair dye / bleaching agent composition has the advantage that it is easy to maintain its shape and is difficult to spill, compared to a liquid hair dye / bleaching agent composition. Under such circumstances, the aerosol foam hair dye / bleaching agent composition is preferably used for hair dyeing (hair dyeing) or decolorization.

  As an aerosol foam hair dye / bleaching agent composition, for example, those disclosed in Patent Documents 1 and 2 are known.

  Before applying to the hair, the aerosol foam hair dye / bleaching agent composition should have good foam shape retention (so-called foam retention) in order to suppress dripping and splashing due to foam crushing. Is desired. On the other hand, it is desired that the foam is quickly crushed after being applied to the hair. Foam-like hair dye / bleaching agent composition is bulky compared to other dosage forms such as cream and so on, and tends to reduce the amount of each component used for hair dyeing / decoloring treatment in contact with hair. It is. Therefore, after applying to hair, it is preferable that bubbles are crushed quickly in order to efficiently infiltrate each component in the composition.

  However, if an attempt is made to improve the shape retention of the foam before application, the foam will not easily collapse after application. Further, if the foam crushing after application is attempted to be accelerated, the composition does not foam before application. As described above, it is very difficult to obtain an aerosol foam hair dye / bleaching agent composition that has good foam retention before application and fast foam crushing after application, which are compatible with each other.

  In addition, aerosol foam hair dye / bleaching agent compositions are generally said to have a strong irritating odor compared to other dosage forms such as creams having equivalent hair dyeing power and lightness. Yes. The main cause of this irritating odor is a volatile alkaline agent blended in the composition.

  As disclosed in Patent Document 1, the aerosol foam hair dye / bleaching agent composition contains ammonia as an alkaline agent. Since ammonia is volatile, when the stock solution of the composition is discharged into a foamy composition, the ammonia is volatilized from the composition and an irritating odor may be felt.

  Therefore, in order to reduce the irritating odor, Patent Document 2 discloses an aerosol foam hair dye / bleaching agent composition in which the amount of ammonia is reduced or no ammonia is added. Further, Patent Document 2 discloses an aerosol foam hair dye / bleaching agent composition containing a non-volatile alkanolamine as an alkali agent.

  Further, as disclosed in Patent Document 2 and the like, when the amount (concentration) of ammonia in the composition is low, the hair dyeing power of the composition is lowered and the lightness of the hair after treatment is lowered. was there.

  In addition, if the composition contains alkanolamine, the hair after treatment may be squeezed and the feel of the hair may be deteriorated. Moreover, the alkanolamine may have a defoaming action and may reduce the shape retention of the foam of the composition.

  The object of the present invention is an aerosol-type foamy hair dye which has an irritating odor suppressed, has a good touch of hair after hair dyeing or decoloring treatment, has good shape retention of foam before application, and quickly crushes after application. A depigmenting agent composition and a hair dyeing / decoloring method using the composition.
