Description

  The present invention relates to an oxidative hair dye composition. More specifically, the present invention uses a specific quaternary ammonium salt and a specific fatty acid ester component and / or a specific nonionic surfactant component to mix and use each component of an oxidative hair dye. The present invention relates to an oxidative hair dye composition that suppresses an unpleasant odor during hair treatment and further improves operability during hair dyeing treatment.

For hair dyes such as oxidative hair dyes and acidic hair dyes, uniform dyeing without dyeing unevenness is required. Moreover, in hair dyes using alkaline agents such as oxidative hair dyes, it is strongly required to suppress hair damage.
Japanese Patent Application Laid-Open No. 04-164018 is a publication relating to the application of the present applicant, and discloses a hair dye containing a specific quaternary ammonium salt as defined in claim 1. This hair dye is less likely to cause uneven dyeing even when an unskilled person performs the hair dyeing process, and also when the hair dye is an oxidative hair dye that performs the hair dyeing process in an alkaline state. There is little risk of hair damage due to hair treatment.

  By the way, although the hair dye disclosed in Patent Document 1 is an excellent hair dye that hardly causes uneven dyeing and hair damage, it has been found that the room for further improvement is left by subsequent research. That is, the hair dye disclosed in Patent Document 1 has not been sufficient in the following points (1) and (2).

  (1) Suppression of unpleasant odors when mixing and using each agent such as the first agent and the second agent.

  (2) The operability that it is easy to scoop with a brush at the time of hair dyeing operation and has good elongation when applied to hair.

  Accordingly, the present invention solves the problem of providing an oxidation hair dye in which the above points (1) and (2) are sufficiently improved while maintaining the advantages of the hair dye disclosed in Patent Document 1. Technical issues that should be

(First invention)
The structure of the 1st invention of this application for solving the above-mentioned subject is an oxidative hair dye composition containing the following (A) ingredient and (B) ingredient.

  (A) One or more quaternary ammonium salts represented by the following “formula 3” formula.

( "Formula 3" formula R _1, R ₂ each represents an alkyl group having 1 to 3 carbon atoms in may be R ₁ and R ₂ are mutually the same or different, R ₃ is "Formula 4" formula R ₄ is an alkyl group or alkenyl group having 1 to ₄ carbon atoms, and X ⁻ is an anion selected from a chlorine ion or a bromine ion.

(In the “Chemical Formula 4” formula, R ₅ represents an alkyl group having 1 to 4 carbon atoms, and n is an integer of 3 to 60.)
(B) 1 or more types chosen from the following (B1) component and (B2) component.

  (B1) Fatty acid glyceryl ester.

  (B2) Polyoxyethylene / polyoxypropylene alkyl ether, wherein the alkyl group has 1 to 24 carbon atoms, and the added mole number a of oxypropylene and the added mole number b of oxyethylene are each 1 or more. An integer of 5 ≦ a + b ≦ 100.

It is an oxidative hair dye composition whose ratio (B) / (A) is in the range of 0.1-10.

  Since the oxidative hair dye composition of the present invention contains one or more quaternary ammonium salts represented by the formula (3) as the component (A), the oxidative dyeing hardly causes uneven dyeing and hair damage. Hair treatment can be performed. The reason why such an effect is obtained is that (1) since the quaternary ammonium salt represented by the “chemical formula 3” is a cationic surfactant, its hydrophilic group tends to be negatively charged in water. Adsorbing to the surface and attracting the dye by the oleophilic group of the quaternary ammonium salt, so that the dye can uniformly adhere to the hair surface and reduce dyeing unevenness of the hair dye. It can be pointed out that the quaternary ammonium salt adsorbs on the surface of the hair, thereby reducing the damage caused by the alkaline hair dye on the cuticle on the hair surface.

  Further, as an important effect, the oxidative hair dye composition of the present invention comprises such a component (A), a fatty acid glyceryl ester and / or a specific polyoxyethylene / polyoxypropylene alkyl ether as the component (B). Therefore, the unpleasant odor at the time of mixing and using each agent of the oxidation hair dye is effectively suppressed, and the operability of the oxidation hair dye is excellent.

These effects in the present invention are such that the mass ratio (B) / (A) of the total content of the component (A) and the total content of the component (B) at the time of use of the oxidative hair dye composition is 0.1 to 0.1. Particularly preferably, it is within the range of 10.

However, the cationic surfactant contained in the composition is essentially different from the component (A) of the present invention in that R1 to R4 shown in the general formula are all alkyl groups, etc. The effect of the invention that “glosses” is completely different from that of the present invention. JP 07-118131 A Japanese Patent Laid-Open No. 09-1000022 Japanese Patent Laid-Open No. 2004-099549 Further, the above-mentioned Patent Document 3 states that “a liquid or emulsion preparation containing a highly viscous cream dye-containing composition and an oxidizing agent and polyoxyethylene / polyoxypropylene alkyl ether”. The hair oxidative dyeing agent obtained by mixing with a product "is disclosed, but this hair oxidative dyeing agent does not contain the component (A) of the present invention, and the effect of the invention is" ease of mixing, It only points out "viscosity suitable for application by container".

  Next, the above Patent Document 4 discloses an “emulsion hair dye composition containing polyoxyethylene / polyoxypropylene alkyl ether, higher alcohol, and hair dyeing dye”, and this hair dye composition. However, as the cationic surfactant, the component (A) of the present invention is not disclosed, and as an effect of the invention, “suppression of unpleasant odors during mixing use” is disclosed. , "Operability" is not pointed out.

  Furthermore, the above-mentioned Patent Document 5 also discloses “a transparent liquid oxidative hair dye first agent composition containing polyoxyethylene / polyoxypropylene alkyl ether”, and this composition also contains a cationic surfactant. However, there is no specific disclosure about this cationic surfactant, and the effect of the invention does not point out, for example, “suppression of unpleasant odor at the time of mixed use, operability” and the like.
