For example, components other than the alkaline agent contained in the first agent described above may be appropriately contained within a range that does not impair the effects of the present invention.

Since the dosage form of the second agent contains hydrogen peroxide as an essential component, it is configured as a liquid, a gel, a foam, and a cream. Examples of the liquid include an emulsion.
The method for preparing the second agent is prepared by mixing each component constituting the second agent. The mixing order of each component which comprises a 2nd agent is not specifically limited. Preferably, before mixing (A) hydrogen peroxide and (B) amphoteric surfactant, an amphoteric surfactant aqueous solution containing components other than hydrogen peroxide is first prepared. As the amphoteric surfactant aqueous solution, for example, if there are (B) amphoteric surfactant, (D) water, and other components blended as necessary, a part or all of them are mixed, and (C) An aqueous solution when an alkali metal inorganic salt is blended may be mentioned. In addition, if there is (C) an inorganic salt of alkali metal, (D) water, and other components blended as necessary, part or all of them are mixed, and (B) amphoteric surfactant is blended An aqueous solution is used.

If the content of the alkali metal inorganic salt is less than 0.1% by mass, the pH stability of the second agent is lowered, and the stability of hydrogen peroxide may be lowered. If the content of the alkali metal inorganic salt exceeds 20% by mass, the pH stability of the second agent is lowered, and the stability of hydrogen peroxide may be lowered.

  The mass ratio (B / C) of the content of (B) amphoteric surfactant to the content of inorganic salt of (C) alkali metal in the amphoteric surfactant aqueous solution is preferably 1.5 to 50, more preferably It is 2 to 25, more preferably 2 to 10, and most preferably 2.5 to 7.5.

For example, (B) (D) water is mixed with 0.5 to 4 parts by weight, more preferably 1 to 3 parts by weight with respect to 1 part by weight of the amphoteric surfactant. A preparation method in which an inorganic salt is added is preferred. If the amount of water added is less than 0.5 parts by mass, the solubility of the amphoteric surfactant may be reduced. On the other hand, if the amount of water added exceeds 4 parts by mass, the concentration of (B) the amphoteric surfactant in the amphoteric surfactant aqueous solution decreases, the pH stability of the second agent decreases, and the stability of hydrogen peroxide. May decrease.

  For example, (C) after mixing (D) water, preferably 5-30 parts by mass, more preferably 10-20 parts by mass with 1 part by mass of (C) inorganic salt of alkali metal, and then (B) amphoteric surfactant. A preparation method in which is added is preferred. If the amount of water added is less than 5 parts by mass, the solubility of the alkali metal inorganic salt may be reduced. On the other hand, if the amount of water added exceeds 30 parts by mass, the concentration of the inorganic salt of (C) alkali metal in the amphoteric surfactant aqueous solution decreases, the pH stability of the second agent decreases, and the stability of hydrogen peroxide May decrease.

(A) If the concentration of hydrogen peroxide is less than 25% by mass, the stability of hydrogen peroxide in the second agent may decrease. On the other hand, when the concentration of hydrogen peroxide in the hydrogen peroxide solution exceeds 40% by mass, it is difficult to obtain a commercial product and the decomposition rate of hydrogen peroxide during storage may increase.

  A hair bleaching / destaining agent is prepared by mixing the first agent and the second agent at the time of use. The dosage form of the mixture is not particularly limited, and may be any of liquid, gel, foam, and cream. The required amount of the mixture is then applied to the hair, attached to a thin gloved hand, comb or brush.

Therefore, the action of improving the stability of hydrogen peroxide can be further enhanced by improving the pH stability of the second agent.

  The decrease in hydrogen peroxide stability that occurs when hydrogen peroxide and amphoteric surfactant coexist is due to contact between hydrogen peroxide and the amphoteric surfactant, releasing carboxylic acid such as acetic acid, and changing the pH of the aqueous solution. Is believed to be due to First, by preparing an amphoteric surfactant aqueous solution, the alkali metal inorganic salt comes into contact with the amphoteric surfactant, and decomposition of the amphoteric surfactant by hydrogen peroxide added thereafter is suppressed. Thereby, it is considered that the contact between (A) hydrogen peroxide and (B) the amphoteric surfactant is suppressed.
