Among the components (d) used in the present invention, dialkyl carbonate is more preferably used because it can sufficiently protect the hair. The dialkyl carbonate can be used alone or in combination with another component (d). It is preferable that the creamy decolorizing agent contains 5 to 20% by mass of the dialkyl carbonate of the component (d). If it is less than 5% by mass, the protection of the hair becomes insufficient, and if it exceeds 20% by mass, the feel becomes heavy and discoloration is hindered.

In the present invention, an inorganic ammonium salt and / or an organic ammonium salt of the component (e) other than the alkaline salts are blended as an essential component in the creamy decolorizing agent.

In the present invention, one or more surfactants of the component (f) can be added to the creamy decolorizing agent, if necessary. By blending one or more surfactants of the component (f), the cream can be smoothened, storage stability at low and high temperatures (for example, 40 ° C.) can be imparted, and the oxidizing agent and cream used in the present invention can be used. Mixability of the two components of the decolorizing agent can be improved.

Component (f) preferably used in the present invention
Examples of the surfactant include, for example, non-ionic surfactants such as ethylene oxide-added polypropylene glycol, ethylene oxide-hardened castor oil, ethylene oxide cetyl ether, and ethylene oxide stearyl ether; sodium cetyl sulfate, sodium acyltaurine, and tetradecene sulfonic acid. One or more selected from anionic surfactants such as sodium and a mixture of two or more thereof can be mentioned. The component (f) is preferably contained in the creamy decolorizing agent in an amount of 1 to 15% by mass, more preferably 5 to 15% by mass, and particularly preferably 8 to 12% by mass. If the amount is less than 1% by mass, a smooth cream cannot be obtained, and the stability is deteriorated.

In the present invention, if necessary, one or more auxiliaries and additives of the component (g) can be added to the creamy decolorizing agent. Component (g) is preferably contained in the creamy decolorizing agent in an amount of 0.1 to 5% by mass, more preferably 1 to 5% by mass, and particularly preferably 2 to 5% by mass.
-4% by mass is desirable. If it is less than 0.1% by mass, stability of the dosage form cannot be obtained, and if it exceeds 5% by mass, the dosage form cannot be made uniform, which is not preferable.

In this case, these added amounts are those generally used in such formulations, for example about 0.1 to 3% by weight each of silicium dioxide and the chelating agent,
The coloring agent and the fragrance are each used in an amount of about 0.01 to 1% by mass.

In the present invention, it is desirable that the creamy decolorizing agent does not contain water. However, if necessary, water may be contained if it is 2.5% by mass or less.

In the present invention, the creamy decolorizing agent is mixed with an oxidizing agent, preferably an aqueous solution of hydrogen peroxide or an oil-in-water emulsion containing hydrogen peroxide, before use, to give a slurry which can be applied. In this case, for example, mixing can be performed by shaking in a petri dish or in a coating container.

In the present invention, the mixing ratio of the creamy decolorizing agent and the oxidizing agent is 1: 1 to 1: 3 when a hydrogen peroxide solution containing 1 to 12% by mass of the active ingredient or an emulsion is used. At a ratio of 1: 4, there is no viscosity and the decolorizing power is weak. On the other hand, at a ratio of less than 1: 1, it is difficult to mix and cannot be applied to hair due to its high viscosity. In particular, even at a ratio of 1: 3, the conditioning effect is good, and the feel of the hair after the treatment is excellent as compared with conventional products. A hydrogen peroxide solution or emulsion containing 1 to 12% by mass of the active ingredient is preferred, and a hydrogen peroxide solution or emulsion containing 1 to 6% by mass, particularly preferably 3 to 6% by mass of the active ingredient is more desirable. If the amount is less than 1% by mass, the hair is not bleached,
If the amount is more than mass%, decolorization is too strong, resulting in damaged hair, and both are not preferred.

The hair decolorizing agent prepared by mixing the creamy decolorizing agent with an aqueous hydrogen peroxide solution or an oil-in-water emulsion containing hydrogen peroxide is uniformly applied on the hair and is applied at room temperature (20 to 25 ° C.). 15 to 60 in
After working for 10 minutes or under heating (30 to 50 ° C.) for 10 to 50 minutes, it is washed away with water.

The creamy decolorizing agent is filled in a tube or a pot according to its viscosity. It can be mixed very easily with the oxidizing agent. That is, they can be easily mixed, and a uniform mixture can be obtained in a short mixing time of 20 seconds or less for 100 g of the preparation.

The hair bleaching agent according to the present invention has excellent applicability, dispersibility and adhesion to hair, as well as easy-to-use viscosity and easy mixing. There is no problem such as a change in the decolorization force with time, and the hair has a high decoloration power, and is characterized in that the hair is gently damaged by the treatment.
