Description

  The present invention relates to an oxidative hair dye using uricase. More specifically, the present invention relates to a non-aerosol foam hair dye composition using uricase, and a non-aerosol foam hair dye comprising the composition and a non-aerosol foam discharge container.

  Since the hair dye has a continuous dyeing effect, it is a two-component oxidative hair dye that mixes a first agent containing an alkaline agent and an oxidation dye and a second agent containing hydrogen peroxide at the time of use. Agents are mainstream.

  However, since a large amount of hydrogen peroxide is blended due to the oxidative polymerization of the oxidative dye, there is a problem that hair is damaged or skin irritation occurs on the scalp. Therefore, attempts have been made to oxidatively polymerize oxidative dyes using various enzymes such as uricase and laccase without using hydrogen peroxide (see, for example, Patent Documents 1 to 6).

  Among these enzymes used for oxidative polymerization, uricase is known to be suitable as a hair dye using an enzyme because it has a peak pH of around 9 and does not exhibit dehydrogenase activity (non-patented). Reference 1). However, when uricase is selected as the enzyme, uric acid, which is the substrate, is poorly water-soluble, which causes a problem in storage stability that it precipitates during storage of the preparation.

  On the other hand, oxidative hair dyes using enzymes are not superior in hair dyeing power than two-part oxidative hair dyes using hydrogen peroxide, and therefore, attempts have been made to use various dosage forms (for example, , See Patent Documents 3 to 6). For example, Patent Document 3 reports an oxidative hair dye having a cream or gel form using larcase. Patent Document 4 reports an aerosol-type foam oxidation hair dye using an oxidase. Patent Document 5 reports a post-foaming oxidative hair dye using uricase. And in patent document 6, the foam oxidation hair dye using laccase is reported.

  Here, when making an oxidative hair dye using uricase, there exists a problem that it is inferior to a hair dyeing power if it makes a cream or a gel form. In addition, when an aerosol-type foam or a post-foamed form is used, since the foam is bulky, the absolute amount (bath ratio) of the drug applied to the hair is smaller than that of the cream or jul form. There is a problem that it is inferior. Furthermore, as in Patent Document 5, if the foam is formed with an anionic foaming agent, there is a problem that the activity of uricase is reduced and the hair dyeing power is reduced.

  Therefore, as a result of intensive studies by the present inventors, a nonionic foaming agent and a thickening polymer were blended in an oxidative hair dye using an enzyme consisting of uric acid, uricase, alkaline agent, oxidative dye and water. It has been found that precipitation of uric acid can be effectively prevented with a hair dye composition.

  Furthermore, when the above hair dye composition is made into a foamy hair dye by a non-aerosol type foam discharge container, it has a good foam and is uniform with no dyeing spots. The present inventors have found that the hair coloring ability equivalent to that of a hair agent can be exhibited, and have completed the present invention.

The present invention
[1] A composition for non-aerosol foam hair dye, comprising uric acid, uricase, nonionic foaming agent, thickening polymer, alkali agent, oxidation dye and water,
[2] The nonionic foaming agent is at least one selected from the group consisting of alkyl glucosides, polyglycerin fatty acid esters, polyglycerin alkyl ethers, and sucrose fatty acid esters. Non-aerosol type foam hair dye composition,
[3] The non-aerosol foam hair dye composition according to claim 1 or 2, wherein the thickening polymer is a starch derivative and / or an alkali-soluble thickening polymer,
[4] The non-aerosol foam hair dye composition according to any one of [1] to [3], wherein the alkali agent is an organic alkali agent;
[5] The composition for a non-aerosol foam hair dye according to any one of [1] to [4], wherein the viscosity at 25 ° C. is 1,000 mPa · s to 8,000 mPa · s. object,
[6] The composition for non-aerosol foam hair dyes according to any one of the above [1] to [5], which further contains a higher alcohol, and [7] the above [1] to [1] 6] A non-aerosol foam hair dye comprising the non-aerosol foam hair dye composition according to any one of [6] and a non-aerosol foam foam container.

  The composition for non-aerosol type foam hair dye of the present invention has an effect of excellent storage stability of uric acid. In addition, the foam-like hair dye discharged from the composition of the present invention with a non-aerosol-type foam discharge container has good foaminess, and the hair that has been dyed is uniformly dyed without staining spots. It exhibits the same hair dyeing power as a two-component oxidation hair dye that uses hydrogen oxide.

  The composition for non-aerosol foam hair dye of the present invention contains uric acid, uricase, nonionic foaming agent, thickening polymer, alkaline agent, oxidation dye and water. A foam-like hair dye discharged from such a composition with a non-aerosol-type foam discharge container exhibits the same hair dyeing power as a two-part oxidative hair dye using hydrogen peroxide.

  When the hair dye is made into a foam, the ratio of the bath to the hair is significantly smaller than that of a cream or gel, and therefore the foam hair dye is usually a cream or gel. It is inferior in hair dyeing power than hair dye. However, although the reason why the foamy hair dye discharged by the non-aerosol type discharge container exhibits excellent hair coloring power is not certain, a large amount of air (oxygen) is contained in the discharged foam. Because of its presence, uric acid is effectively decomposed by uricase, and the carbon dioxide produced improves foaming and further improves the contact ability between the air and the enzyme / substrate. This is presumed to efficiently oxidatively polymerize the agent.

  Each hair dye composition of Examples 1 to 8 and Comparative Examples 1 to 8 was filled in a pump type foam discharge container in the same manner as in Test Example 3, and foam was discharged. After 3 g of the resulting foam was uniformly applied to a white human hair bundle having a weight of 3 g and a length of 10 cm, it was allowed to stand in an atmosphere at 30 ° C. for 20 minutes. The drug was washed with water using a shampoo and then dried with a dryer.

  After 6 g of the hair dye of Comparative Examples 9 to 10 was uniformly applied to a white human hair bundle having a weight of 3 g and a length of 10 cm, the hair dye was left in an atmosphere at 30 ° C. for 20 minutes. The drug was washed with water using a shampoo and then dried with a dryer.

  After 6 g of the hair dye after mixing of Comparative Control A was uniformly applied to a white human hair bundle having a weight of 3 g and a length of 10 cm, it was allowed to stand in an atmosphere at 30 ° C. for 20 minutes. The drug was washed with water using a shampoo and then dried with a dryer.

  Each item of dyeability and hair dyeing power was evaluated according to the following evaluation criteria by 20 expert panelists. The results are shown in Tables 6-7.

<Evaluation criteria for dyeability>
◎: Reply that 16 or more out of 20 people are uniformly dyed and gray hair is not noticeable ○: Reply that 11 to 15 out of 20 people are uniformly dyed and white hair is not noticeable Δ: 6 to 10 out of 20 people Answer that hair is uniformly dyed and gray hair is inconspicuous ×: 5 or less of 20 people are uniformly hair dyed and white hair is inconspicuous

<Evaluation criteria for hair dyeing power>
◎: Reply if 16 or more out of 20 hairs were equal to Comparative A A ○: Reply that 11 to 15 or more out of 20 hairs were comparable to Comparative A A: 20 Reply that 6-10 or more of them are hair dyed equivalently to Control A x: Reply that 5 or less of 20 people are dyed hair equivalent to Control A

  From the results of Tables 3 to 4, it can be seen that the non-aerosol foam hair dye composition of the present invention is excellent in storage stability of uric acid. Moreover, when the composition of this invention is discharged with a non-aerosol type foam discharge container, it turns out that it is excellent in foaming property, and the discharged foam is excellent also in foam quality.

  And from the result of Tables 6-7, the composition for non-aerosol type foam hair dye of this invention is made into 1 agent type gel-like hair dye (Comparative Example 9) or 1 agent type cream-like hair dye without making it a foam. It can be seen that when the hair is treated in the form of the agent (Comparative Example 10), it is inferior in dyeability and hair dyeing power. On the other hand, the non-aerosol foam hair dye of the present invention in the form of foam has the same dyeing ability and hair dyeing power as a normal two-component oxidative hair dye using hydrogen peroxide (Comparative Control A). It can be seen that
