Description

  The present invention relates to a second agent composition of an aerosol type hair dye or a hair bleaching agent.

  Conventionally, it consists of a first agent containing an alkali agent and a second agent containing an oxidant, and the first agent and the second agent are respectively stored in independent aerosol containers, and they are discharged and mixed when used. A two-component aerosol hair dye or hair bleaching agent is known (Patent Documents 1 and 2).

  In such a two-part aerosol product, it is generally known that a high shear force is applied to the agent when the agent is filled into the aerosol container or when the agent is discharged from the aerosol container. ing.

JP 2000-297018 A JP 2004-091359 A

  However, since the shearing force applied to the agent at the time of filling and discharging is very strong, the emulsified structure of the agent is changed, and when used, the viscosity of the agent may be lower than the initially set viscosity. Such a decrease in the viscosity of the agent causes a change in the discharge amount of the agent from the aerosol container. In particular, in a two-component aerosol hair dye or hair bleaching agent, due to the above viscosity change, the first agent discharged from the first agent container and the second agent container discharged from the second agent container There is a possibility that a stable hair dyeing / decoloring effect cannot be obtained because the discharge amount of the two agents is significantly different.

  In addition, in the aerosol hair dye / bleaching agent, if hydrogen peroxide and a cationic surfactant (in many cases counter ions are chloride ions) are used as the second agent, the metal container may corrode. In order to suppress it, it is necessary to select the inner bag and inner surface coat of the metal container, and it takes a lot of labor. If an anionic surfactant is used as the second agent, the hair feel is deteriorated and the pH is low. There is also a problem that it is difficult to use an ionic surfactant.

  Therefore, the present invention uses a ionic surfactant as much as possible and keeps the viscosity of the agent from the aerosol container stable by keeping the viscosity from before the agent is filled into the aerosol container to after being discharged from the aerosol container. The present invention relates to a second agent composition capable of realizing discharge and obtaining a stable hair dyeing / bleaching effect.

  As a result of intensive studies, the present inventor has found that, in the second agent of the aerosol type hair dye or hair decoloring agent, in order to keep the viscosity of the agent constant without using an ionic surfactant as much as possible, the emulsion particle size should be reduced. In addition, it has been found that, for that purpose, it is effective to blend a nonionic surfactant, a higher alcohol and a hydrocarbon in a specific ratio.

This invention is the 2nd agent composition for aerosol type hair dyeing or hair decoloring used by mixing with the 1st agent composition containing an alkaline agent, Comprising: The following component (A)-(D) is contained. The total mass ratio [(C) + (D)] / (B) of components (C) and (D) to component (B) is 1.0 or more and 3.5 or less, and component (D) to component (C) The present invention provides a second agent composition for aerosol hair dyeing or hair bleaching, wherein the mass ratio (D) / (C) is 1.2 or more and 2.2 or less.
(A) Hydrogen peroxide
(B) Nonionic surfactant
(C) Higher alcohol
(D) Hydrocarbon

  The second agent composition of the present invention is capable of stably discharging from the aerosol container because the viscosity is kept constant by suppressing the viscosity reduction due to filling and discharging into the aerosol container. When used as a hair or depigmenting agent, a stable hair dyeing / bleaching effect can be obtained.

Example 1 and Comparative Example 1
The 2nd agent composition of the mixing | blending prescription shown in Table 1 was prepared. Next, the second agent composition was filled in the inner bag of the second container of the double aerosol, and nitrogen gas was filled between the inner bag and the second agent container. By the method shown below, the viscosity and volume average diameter of the second agent composition were measured.

(Viscosity measurement method)
The viscosity of the second agent composition was measured at two time points before filling into the container and immediately after discharging from the container one month after filling into the container. Viscosity (25 ° C) is measured using a B-type viscometer with a helical stand (manufactured by Toki Sangyo Co., Ltd., model TVB-10R, T-BAR STAGE TS-10) and rotated at 10 rpm for 1 minute using a TC rotor. It is the value after.

(Method for measuring volume average diameter of emulsified particles)
The volume average particle size of the emulsified particles was DYNAMIC LIGHT SCATTERING PARTICLE SIZE ANALYZER LB-500 manufactured by HORIBA. This is a value obtained by selecting a refractive index: 1.333) and measuring the volume distribution of the average diameter of the emulsified particles.

Examples 2-7, Comparative Examples 2-5
The 2nd agent composition of the mixing | blending prescription shown in Table 2 and Table 3 was prepared. The volume average diameter of the emulsified particles of the second agent composition was measured by the method described above.
