Description

  The present invention relates to a hair dye, and more particularly to a so-called hair nail polish that dyes hair into a desired color by penetrating and adsorbing the dye into the hair.

  Conventionally, hair dyes that can be easily dyed into the color of your hair (sometimes called hair dyes, hair dyes, coloring agents, hair coloring agents, etc. Many have been developed. Hair dyes and hair manicures are known as common hair dyes.

  A hair dye is one that decomposes the melanin pigment in the hair to lighten the color of the hair, or decolorizes the hair and simultaneously dyes the hair with a dye of the desired color. It is what is done. On the other hand, hair manicure is a method in which a dye is adsorbed on the hair surface without decomposing the melanin pigment, and further, the dye is penetrated into the hair to dye the hair to a desired color.

  In general, hair dyes are characterized by strong dyeing power and good color retention, but have the disadvantage of damaging hair because they contain basic components, oxidizing agents, and the like. On the other hand, many hair manicures do not contain basic components, oxidizing agents, etc., and have the advantage that they do not damage hair compared to hair dies.

  By the way, many hair nail polishes are often made into gels (gels) containing a large amount of anionic or nonionic thickeners, and the above-mentioned increase is applied to the hair after treatment (after applying hair nail polish and washing away). Sticky agent may remain. In other words, as described above, hair nail polish has a drawback that the hair after treatment is firm and firm (it may be expressed that the hair has a so-called coating feeling).

  In addition, as described above, the hair nail polish dyes hair by applying a dye to the hair surface, and has, for example, inferior color persistence (color retention) as compared to a hair dye. In addition, many dyes for general hair manicure use acid dyes, and if the dye is dyed on the scalp during the treatment, it may be difficult to remove the dye from the scalp even if the hair is washed after the treatment. .

  In order to eliminate such drawbacks of hair manicure, for example, there is a hair composition disclosed in Patent Document 1.

Japanese Patent No. 2010-105997

  The hair composition disclosed in Patent Document 1 is a mixture of a dye, an aromatic alcohol, and a nonionic surfactant. As a result, the problem of hair manicure, which is inferior in color persistence (color retention), is solved, and high hair dyeing power (color persistence, color retention) can be maintained.

  In hair manicure, generally, an aromatic alcohol is added together with the dye in order to make the dye adhere to and penetrate into the hair (in order to increase the dyeing power). However, it is known that when an aromatic alcohol is added together with the dye, the dosage form of the hair nail polish is not stable, that is, the storage stability is poor. Therefore, the conventional hair manicure including the above-mentioned Patent Document 1 contains a water-soluble polymer compound (an anionic or nonionic thickener) in addition to a dye and an aromatic alcohol. Many hair-like manicures.

  However, gel-like hair nail polish has a problem in that a thickener remains on the hair after treatment, resulting in a firmness, hardness, and a coating feeling.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to maintain the dyeing power and to provide flexibility and good fingering to the hair even after the treatment (hair slipperiness). ) To provide a hair dye having a treatment effect.

  In order to achieve the above object, the present invention has the following features. That is, the first invention is a hair dye characterized by being an emulsion. The hair dye contains (A) component: basic dye, (B) component: aromatic alcohol, (C) component: cationic surfactant, (D) component: nonionic surfactant, and (E) component: Contains dimethicone or dimethiconol.

  A second invention further comprises (F) component: amino-modified silicone in the first invention.

  The third invention is characterized in that, in the second invention, the weight value of the component (F): amino-modified silicone in the hair dye is lower than the weight value of the component (E): dimethicone or dimethiconol.

  According to a fourth invention, in any one of the first to third inventions, the invention further comprises a polyether-modified silicone having a component (G): HLB (Hydrophile-Lipophile Balance) value of less than 7.

  5th invention WHEREIN: The value of HLB (Hydrophile-Lipophile Balance) of (D) component is 5-15 in any one invention of the said 1st thru | or 4.

  In the sixth aspect, the hair dye according to any one of the first to fifth aspects has a pH of 6 to 8.5.

  7th invention is the hair dye which consists of a 1st agent and a 2nd agent. Here, the first agent is a hair dye according to any one of the first, second, and fourth inventions. On the other hand, the second agent is a treatment agent containing (C) component: cationic surfactant, (E) component: dimethicone or dimethiconol, and (F) component: amino-modified silicone. The second agent is applied after the first agent is applied to the hair.

  ADVANTAGE OF THE INVENTION According to this invention, the hair dye which has the treatment effect of giving the softness | flexibility and the goodness | strength of a finger (slipperiness of hair) to hair, even after a treatment, can be provided, maintaining dyeing power. . In addition, when a multi-agent type, for example, a first agent containing mainly a component for dyeing hair, a component that mainly gives a treatment effect, and a second agent that contains a component that gives a treatment effect, After applying one agent to the hair, the treatment effect can be maintained by applying the second agent to the hair.

  The hair dye according to the present invention contains (A) a basic dye, (B) an aromatic alcohol, (C) a cationic surfactant, (D) a nonionic surfactant, (E) dimethicone or dimethiconol as an essential component. . In addition, the hair dye which concerns on this invention is a hair dye of the emulsified state containing each said essential component (for example, a solvent shall be water).

  Moreover, the hair dye which concerns on this invention mix | blends (F) amino modified silicone, (G) polyether modified silicone, and (H) higher alcohol in addition to each essential component of said (A)-(E). Also good. That is, in addition to the essential components (A) to (E), the components (F), (G), and (H) may be used alone or in combination of two or more.

  In general, many gel-like hair preparations are known. Particularly in hair manicure, a thickener is used. There were problems such as hardness and a feeling of coating. Therefore, for example, an emulsified hair dye (hair manicure) having a low viscosity has been desired.

  The main purpose of hair dyes is to dye hair. In order to effectively permeate dyes into hair, generally aromatic alcohols typified by benzyl alcohol are used. It is blended. In addition, although the aromatic alcohol mix | blended with hair dye can permeate | transmit a dye effectively to hair, when it is set as an emulsification type hair dye, it is known that an emulsified state will become unstable. . Therefore, when obtaining an emulsified hair dye, it is preferable not to mix the aromatic alcohol. However, as described above, the aromatic alcohol contributes to the effect of allowing the dye to penetrate into the hair. Therefore, if the aromatic alcohol is not blended in the hair dye, the main purpose of the hair dye may not be achieved. There is.

  As a result of diligent study, the applicant of the present invention maintains the dyeing power by using the above-described components (A) to (E) as essential components and maintains the dyeing power, and makes the dosage form an emulsion. Later, the present inventors have obtained a hair dye having a treatment effect such as imparting flexibility and good fingering (sliding property of hair) to the hair.

(Examples 1 to 4 and Comparative Examples 1 to 4)
According to the composition described in Table 1, hair dyes according to Examples 1 to 4 and Comparative Examples 1 to 4 were adjusted, and each hair dye was evaluated according to Test Examples 1 to 3 described above. Specifically, the hair dyes according to each of Examples 1 to 4 and Comparative Examples 1 to 3 mainly have different pH values for the respective hair dyes.

  As can be seen from Examples 1 to 4 in Table 1, all have good effects on “dyeing power”, “color retention”, “feel (flexibility)”, and “feel (slidability)”. It was. On the other hand, as seen in Comparative Examples 1 to 4 in Table 1, all have good effects on “dyeing power”, “color retention”, “feel (flexibility)”, and “feel (slidability)”. Was not obtained.

  That is, it was found that the pH value of the hair dye is preferably about 6 or more and less than 9, and more preferably near neutrality (pH = 7). In other words, if the pH value of the hair dye exceeds 9 (as it becomes a base), good results cannot be obtained with respect to the treatment effect such as giving the hair flexibility or good fingering (hair slipperiness), It was found that the main purpose (dyeing power, color retention) of the hair dye could not be achieved when the pH value of the hair dye was less than 6.

  In addition, as a result of evaluating the hair dye which concerns on each of Example 1-Example 4 according to the above-mentioned Test Example 4, as for any of Example 1-Example 4, separation is not seen at all about "stability of an emulsification state". Excellent results were obtained.

(Examples 5 to 17 and Comparative Examples 5 to 6)
According to the compositions described in Table 2 and Table 3, hair dyes according to Examples 5 to 17 and Comparative Examples 5 to 6 were prepared, and each hair dye was evaluated according to Test Examples 1 to 4 described above. Specifically, the hair dyes according to Examples 5 to 17 and Comparative Examples 5 to 6, respectively, are mainly contained in the respective hair dyes, dimethicone, dimethiconol (each including a difference in viscosity), Each amino-modified silicone is different.

  As can be seen in Examples 5 to 17 of Table 2 and Table 3, good effects were obtained for both “dyeing power” and “color retention”.

  Moreover, when the hair dye which concerns on each of Example 5-Example 17 of Table 2 and Table 3 and the hair dye which concerns on each of Comparative Examples 5-6 are compared, neither dimethicone nor dimethiconol is mix | blended with the hair dye. In particular, good results could not be obtained especially for “feel (flexibility)” (that is, flexibility of hair).

  As can be seen from Examples 12 to 17 in Table 2 and Table 3, both “feel (flexibility)” and “feel (slidability)” were excellent. That is, it can be seen from this result that amino-modified silicone is preferably blended with the hair dye together with dimethicone and dimethiconol. More specifically, it is preferable that the sum of the weights of dimethicone and dimethiconol in the hair dye (which should contain at least one of dimethicone and dimethiconol) exceeds the weight value of the amino-modified silicone. .

  In addition, as a result of evaluating the hair dye which concerns on each of Example 5-Example 17 according to the above-mentioned Test example 4, as for any of Example 5- Example 17, separation is not seen at all about "stability of an emulsified state". In addition, only a slight separation was observed, and good results were obtained.

  Furthermore, as seen in Examples 15 to 17, when a polyether-modified silicone is blended in the hair dye, and the HLB value of the polyether-modified silicone is less than 7, “emulsification stability” No separation was observed with respect to and excellent results were obtained.

(Examples 18 to 22, Comparative Example 7)
According to the compositions described in Table 4, hair dyes according to Examples 18 to 22 and Comparative Example 7 were prepared, and each hair dye was evaluated according to Test Examples 1 to 4 described above. Specifically, the hair dyes according to Examples 18 to 22 and Comparative Example 7 are nonionic surfactants (including differences in HLB values) mainly contained in the respective hair dyes. Each is different.

  As can be seen from Example 18 to Example 22 in Table 4, good results were obtained for “dyeing power”, “color retention”, “feel (flexibility)”, and “feel (slidability)”. Also, good results were obtained for "stability of emulsified state". On the other hand, with regard to “stability in the emulsified state” of Comparative Example 7 in Table 4, most of the separation was observed, and good results were not obtained.

  For example, when Example 19 was compared with Examples 20 to 22, Example 19 was superior in terms of “stability in the emulsified state”. That is, from the viewpoint of stabilizing the emulsification of the hair dye, it is preferable to use an HLB value of about 5 to 15 for the nonionic surfactant added to the hair dye. Moreover, about Example 18, the excellent result was acquired about "stability of an emulsified state", the nonionic surfactant whose HLB value is about 5-15 is mix | blended, More preferably, the value of HLB is 5-5. It is preferable to blend a nonionic surfactant having a relatively high HLB value (16 or more, about 20) with a nonionic surfactant of about 15.

(Example 23 to Example 24, Comparative Example 8)
According to the composition described in Table 5, hair dyes according to Examples 23 to 24 and Comparative Example 8 were prepared, and each hair dye was evaluated according to Test Examples 1 to 4 described above. Specifically, the hair dyes according to each of Examples 23 to 24 and Comparative Example 8 are different in higher alcohols mainly contained in the respective hair dyes.

  As can be seen from Example 23 to Example 24 in Table 5, good results were obtained for “dyeing power”, “color retention”, “feel (flexibility)”, and “feel (slidability)”. As for “emulsification stability”, excellent results were obtained. On the other hand, with regard to “stability of emulsified state” of Comparative Example 8 in Table 5, most of the separation was observed, and good results were not obtained.

  From this, it was found that the higher alcohol is effective in stabilizing the emulsified state when the hair dye is an emulsion.

(Example 25 to Example 29, Comparative Example 9)
According to the composition described in Table 6, hair dyes according to each of Examples 25 to 29 and Comparative Example 9 were prepared, and each hair dye was evaluated according to Test Examples 1 to 4 described above. Specifically, the hair dyes according to Example 25 to Example 29 and Comparative Example 9 are different from each other in the cationic surfactant contained mainly in each hair dye.

  As seen in Examples 25 to 29 in Table 6, “dyeing power”, “color retention”, “feel (flexibility)”, “feel (slidability)”, and “stability in emulsified state” Good effects were obtained in each case. On the other hand, as seen in Comparative Example 9 in Table 6, both “feel (flexibility)” and “feel (slidability)” were inferior, and in particular, “feel (flexibility)” was inferior.

  As a result, it is found that the cationic surfactant has an effect of eliminating stiffness and itchiness on the hair after the treatment (after applying the hair dye and washing away), in other words, an effect of particularly imparting flexibility to the hair. It was.

(Example 30 to Example 34, Comparative Example 10)
According to the composition described in Table 7, hair dyes according to each of Examples 30 to 34 and Comparative Example 10 were prepared, and each hair dye was evaluated according to Test Examples 1 to 4 described above. Specifically, the hair dyes according to each of Examples 30 to 34 and Comparative Example 10 are different from each other in aromatic alcohol (including a difference in concentration) contained in each hair dye.

  As seen in Example 30 to Example 34 of Table 7, “dyeing power”, “color retention”, “feel (flexibility)”, “feel (slidability)”, and “stability in emulsified state” Good results were obtained for each. On the other hand, as seen in Comparative Example 10, both “dyeing power” and “color retention” were inferior.

  In addition, as seen in Example 30 to Example 34, the concentration of the aromatic alcohol blended in the hair dye is 0.1% by weight or more, preferably 0.5% by weight to 6% by weight, more preferably When the content was 2% by weight to 5% by weight, excellent results were obtained with respect to the effect of promoting dye penetration and enhancing dyeability. In addition, as the concentration of the aromatic alcohol blended in the hair dye increases, the penetration of the dye can be promoted and the dyeability can be increased. However, “feel (flexibility)”, “feel (slipperiness)”, “ Good results cannot be obtained for the stability of the emulsified state.

(Example 35-Example 36, Comparative Examples 11-12)
First, according to the composition shown in Table 8 as the second agent, the second agent of the hair dye according to each of Examples 35 to 36 and Comparative Example 11 was prepared. And the hair dye of Example 1 mentioned above was made into the 1st agent, and after applying the 1st agent to hair, plain rinse was carried out after shampooing and the 2nd agent shown in Table 8 was applied to hair. In Comparative Example 12, the second agent was not used, that is, the hair dye of Example 1 described above was used as the first agent, and after applying the first agent to the hair, plain rinse after shampooing was performed. Only.

  As evaluation items, in addition to Test Examples 1 to 4 described above, Test Example 5 was performed for evaluation.

  As seen in Examples 35 to 36 of Table 8, “dyeing power”, “color retention”, “feel (flexibility)”, “feel (slidability)”, and “stability of emulsified state” Good results were obtained for each. In addition, by applying the first agent to the hair and then applying the second agent to the hair, an excellent result of “feel (sustainability)” is obtained, and the feel (flexibility, slipperiness) immediately after the treatment is obtained. I found it to last.

  On the other hand, as seen in Comparative Example 11 in Table 8, after the first agent was applied to the hair, the second agent was applied to the hair, but a good effect on “feel (sustainability)” was not obtained, It was found that the feeling immediately after the treatment was not so long. From this, it was found that it is particularly preferable that the second agent contains amino-modified silicone.

  Furthermore, as seen in Comparative Example 12 in Table 7, when the second agent was not applied, it was found that a good effect on “feel (sustainability)” was not obtained and the feel immediately after the treatment was not sustained. It was.

  The hair dye according to the present invention has so-called hair manicure or the like that has a treatment effect such as imparting flexibility and good fingering (sliding property of hair) to the hair even after the treatment while maintaining the hair coloring power. In particular, it is useful as a hair manicure for business use used in a hair salon or the like.
