Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dye, and more particularly, to a two-part foam hair dye which does not corrode a container, has good hair dyeing power, and has no volatilization of ammonia at the time of injection. The present invention relates to an agent composition and an aerosol product containing a two-part foam hair dye composition.

[0002]

2. Description of the Related Art Conventionally, a first agent containing an oxidation dye and ammonia as a hair dye and a second agent containing an oxidant have been used.
Two-part foam hair dye compositions have been used. In this two-part foam hair dye composition, when the first part and the second part are mixed at the time of use, the generation of oxygen from the oxidizing agent is accelerated by ammonia, and the oxygen decomposes the melanin pigment in the hair. At the same time, the dyeing is carried out by polymerizing the oxidation dye that has penetrated into the hair and fixing it to the hair.

Further, this two-part foam hair dye composition is disclosed in Japanese Patent Application Laid-Open No. 10-287534.
By filling and using an aerosol container having a simultaneous ejection mechanism, it is used as a foamy dosage form. That is, the first agent and the second agent are separately filled in the aerosol container, and at the time of use, the first agent and the second agent are mixed from one outlet to form a foam. Discharged.

In the aerosol container, a portion filled with the first agent is provided with an inner coating layer or an inner bag made of a material resistant to ammonia in order to prevent corrosion by ammonia. Means of filling one agent have been adopted.

[0005]

However, even when such measures are taken, although the frequency of occurrence is low, pinholes may be formed in the inner coating layer of the aerosol container, and the storage environment of the aerosol container may be reduced. Is poor, the inner bag may be ruptured or the liquid may leak.

[0006] In the above case, the inner wall of the aerosol container is corroded by ammonia, and a substance produced by the corrosion is mixed into the first agent, thereby deteriorating the performance of the two-pack foam hair dye composition. There was a problem. In addition, the two-part foam hair dye composition is foamy after being discharged from the aerosol container, so that the surface area is large and the volatilization of ammonia is fast. Therefore, after discharging from the aerosol container, the ammonia concentration in the two-part foam hair dye composition decreases over time, and there is a problem that sufficient hair dyeing power cannot be obtained. In particular, when it takes a long time to remove the two-part foam hair dye composition from the container and apply it to the hair, the decrease in the ammonia concentration is large and the hair dyeing power is significantly reduced.

Further, as described above, there is a problem that an irritating odor is generated due to intense volatilization of ammonia. The present invention has been made in view of the above points, and a two-part foam hair dye composition and a two-part foam hair dye composition that do not corrode an aerosol container, have good hair dyeing power, and have no volatilization of ammonia during injection. It is an object of the present invention to provide an aerosol product containing a composition foam hair dye composition.

[0008]

Means for Solving the Problems and Effects of the Invention (1) The invention of claim 1 is a two-part foam comprising a first part containing an alkaline agent and a second part containing an oxidizing agent. A hair dye composition, wherein the ratio of the amount of ammonia contained in the alkali agent to the total amount of the alkali agent is 30% by weight or less, and the second agent contains an ammonium salt. The gist of the present invention is a two-part foam hair dye composition.

The two-part foam hair dye composition of the present invention comprises a first part containing an alkaline agent and a second part containing an oxidizing agent. Used as an agent or hair dye. This two-part foam hair dye composition has a foamy dosage form at the time of use. For example, the first part and the second part are stored in an aerosol container together with a propellant, respectively. Occasionally, the mixture is discharged together with the propellant to form a foamed dosage form.

[0010] In particular, in the two-part foam hair dye composition of the present invention, the amount of ammonia contained in the alkaline agent is not more than 30% by weight based on the total amount of the alkaline agent. In a state in which the second agent is mixed), the alkali agent contained in the first agent gradually reacts with the ammonium salt contained in the second agent to continuously generate ammonia.

In addition, the two-part foam hair dye composition, when used, generates oxygen from the oxidizing agent by the ammonia produced by the above reaction and the alkali agent originally contained in the first part. Promotes and decomposes the melanin pigment in the hair (decolorizes) by the generated oxygen.

Further, when the two-part foam hair dye composition of the present invention contains a dye, for example, the hair is dyed by fixing the dye to the hair. In the case of performing hair dyeing, ammonia generated by the above-described reaction has the effect of swelling the hair, thereby promoting the penetration of the dye into the hair, and improving the hair dyeing effect.

The two-part foam hair dye composition of the present invention has the following advantages due to the above constitution and action. In the two-part foam hair dye composition of the present invention, since the amount of ammonia contained in the alkali agent is small (30% by weight or less), the ammonia concentration in the first part is low. Therefore, the first
Corrosion of the inner wall of a container (for example, an aerosol container) containing the agent and deterioration of the two-part foam hair dye composition accompanying the corrosion do not occur.

The two-part foam hair dye composition of the present invention has a large surface area because the dosage form at the time of use is foamy.
Although the ammonia is easily volatilized, the concentration of ammonia in the two-part foam hair dye composition is unlikely to decrease even when the time elapses in a foamed state. That is, the two-part foam hair dye composition of the present invention is obtained by mixing the first part and the second part (for example, mixing the first part and the second part from an aerosol container,
After discharging in a foamed dosage form), the alkaline agent contained in the first agent and the ammonium salt contained in the second agent continuously react, and ammonia is continuously generated. Therefore, even if there is volatilization of ammonia, the concentration of ammonia in the two-part foam hair dye composition should be sufficient to promote the generation of oxygen from the oxide and to perform the decolorization or hair dyeing action. Will be kept.

[0015] Therefore, the two-part foam hair dye composition of the present invention has sufficient decolorizing power and hair coloring power. In addition, the two-part foam hair dye composition of the present invention is obtained by mixing the first part and the second part to form a foamed form, and then, after a lapse of time, the decolorizing power and the hair coloring power. Since the water content does not decrease, there is an advantage that the work time for applying the two-part foam hair dye composition to the hair can be extended.

The two-part foam hair dye composition of the present invention contains a very small amount of ammonia (ammonia originally contained in an alkali agent) before mixing the first and second parts. There is no irritating odor due to the volatilization of ammonia. Further, after the first and second agents are mixed, ammonia is continuously generated by the above-described reaction, but the rate of volatilization from the generated ammonia does not exceed the generation rate of the reaction.

Therefore, for example, the volatilization rate of ammonia can be suppressed by appropriately setting the types and amounts of the alkali agent and the oxidizing agent, etc., and limiting the ammonia generation rate. That is, in the present invention, the rate of ammonia volatilization from the two-part foam hair dye composition is low, and the generation of pungent odor is small.

If it exceeds 20% by weight, no further effect can be obtained.

The oxidizing agent is, for example, hydrogen peroxide, and its compounding amount is, for example, 0.1 to 9% by weight based on the total amount of the second agent. If the amount is less than 0.1% by weight, good hair dyeing results cannot be obtained.
