Japanese Patent Application Laid-Open No. 2011-51889 Japanese Unexamined Patent Publication No. 2001-064135

For example, a persulfate as described in Patent Document 1 is known as a component having high decolorization performance, but there is a risk of causing a rash or the like depending on the user.

In the case of a two-agent hair dye or hair bleaching agent as described in Patent Document 2, the first agent typically contains an alkaline component such as ammonia, and the second agent contains hydrogen peroxide. Etc. contains an oxidizing agent. When the first agent and the second agent are applied to the hair, the hydrogen peroxide that has permeated into the hair is decomposed by the alkaline component that has permeated at the same time to generate oxygen, which decomposes the melanin pigment in the hair. Hair can be bleached. However, alkaline components such as ammonia may cause an unfavorable odor.

For this reason, it has been desired to develop a new agent exhibiting a hair bleaching mechanism different from the conventional one so that variations related to bleaching can be increased and the hair can be suitably used for various users.

Hereinafter, embodiments of the present disclosure will be described in detail. The present disclosure is not limited to the following embodiments, and can be variously modified and implemented within the scope of the gist of the invention.

The hair bleaching or dyeing composition of the present disclosure (sometimes referred to simply as a "composition") contains a hydrocarbon having 8 to 16 carbon atoms as a hair bleaching accelerator.

Although not limited by the principle, it is considered that the principle of action that such a composition can exhibit a novel hair bleaching mechanism that has never existed is as follows.

For example, as a typical hair bleaching agent or hair dye, a first agent containing an alkaline agent and a second agent containing an oxidizing agent are used. The alkaline agent contained in the first agent has a function of swelling the hair, whereby the alkaline agent of the first agent and the oxidizing agent of the second agent can permeate into the hair. It is known that the alkaline agent that has penetrated into the hair decomposes the oxidizing agent in the hair to generate oxygen, whereby the melanin pigment in the hair is decomposed and the hair can be decolorized.

The present inventor further improves the decolorization property of hair when a specific hydrocarbon, that is, a hydrocarbon having 8 to 16 carbon atoms is blended with, for example, the above-mentioned first agent or second agent. I found that. Surprisingly, the present inventor has also found that this effect cannot be achieved with hydrocarbons having 7 or less carbon atoms and 17 or more carbon atoms.

Although the principle of action of the hair bleaching promoting performance by a specific hydrocarbon is not clear, the present inventor expands the invasion route of various components on the hair surface formed by the hair swelling action of the alkaline agent. However, it is believed that the penetration of alkaline agents and oxidizing agents that contribute to decolorization into the hair is further improved. Specifically, when the first agent and the second agent having a conventional composition that do not contain a specific hydrocarbon are used, the alkaline agent and the oxidizing agent contained therein are relatively small in the hair. Only the remaining part was present outside the hair in a state where it could not contribute to decolorization, but when the first agent containing a specific hydrocarbon was used, the amount of alkaline agent and oxidizing agent was relatively large. Since it has become possible to penetrate into the hair at a rate, it is considered that the bleaching performance of the hair can be further improved as compared with the conventional one.

As described above, since a specific hydrocarbon can exhibit a novel hair bleaching mechanism that has never existed before, for example, even if the amount of an alkaline agent or the like used so far is reduced, the same bleaching performance is obtained. Can be demonstrated. That is, it is considered that the use of a specific hydrocarbon as a hair bleaching accelerator can contribute to the reduction of the amount of the bleaching contributing component such as an alkaline agent.

<< Composition for hair bleaching or hair dyeing >>
The hair bleaching or dyeing composition of the present disclosure has the ability to promote hair bleaching. Such hair bleaching promoting performance can be evaluated by, for example, the L value representing the brightness in the color difference formula of the hunter. When the L value is close to 0, black is intended, and when it is close to 100, white is intended. Therefore, it can be said that the larger the L value, the better the decolorization promoting performance. The L value of the hair to which the hair bleaching or dyeing composition of the present disclosure is applied is 18.5 or more, 19.0 or more, 19.5 or more, 20.0 or more, 20.5 or more, 21.0 or more. 2, 21.5 or more, or 22.0 or more can be achieved. The upper limit of the L value is not particularly limited, but may be, for example, 30.0 or less, 28.0 or less, or 25.0 or less.

This decolorization promotion performance can also be evaluated by the ΔL value. For example, the L value (reference value) of hair bleached using a two-agent hair bleaching agent containing a first agent containing an alkaline agent and a second agent containing an oxidizing agent, and carbon as a hair bleaching accelerator. The L value (evaluation value) of hair bleached using a first agent containing a hydrocarbon having 8 to 16 atoms and an alkaline agent and a two-agent hair bleaching agent comprising the above second agent is as follows. It can be calculated by introducing it into Equation 1:
ΔL value = L value (evaluation value) -L value (reference value) ... Equation 1

The ΔL value of the hair to which the hair bleaching or dyeing composition of the present disclosure is applied is 0.3 or more, 0.5 or more, 0.7 or more, 1.0 or more, 1.5 or more, 2.0 or more. , Or 2.5 or more can be achieved. The upper limit of the ΔL value is not particularly limited, but may be, for example, 5.0 or less, 4.5 or less, or 4.0 or less.

<Hair bleaching accelerator: hydrocarbon with 8 to 16 carbon atoms>
The hair bleaching or dyeing composition of the present disclosure contains a hydrocarbon having 8 to 16 carbon atoms as a hair bleaching accelerator. Such hydrocarbons are typically liquid at room temperature, for example, in an atmosphere of 15 ° C. to 35 ° C., and have the ability to easily volatilize. Therefore, in the present disclosure, such hydrocarbons may be referred to as "volatile hydrocarbons". Further, in the present disclosure, the "hair bleaching accelerator" refers to an agent capable of improving the bleaching property of hair when such an agent is blended, that is, an agent capable of brightening the lightness of hair as compared with the case where such agent is not blended. Intended. Specifically, an agent capable of achieving the above-mentioned L value or ΔL value can be intended.

The volatile hydrocarbon may be used alone as a hair bleaching accelerator, or, for example, the first agent used in a two- or three-agent hair bleaching or hair dyeing kit. It may be used as at least one component of up to the third agent. Although the principle is not clear, if a volatile hydrocarbon is added to the first agent and / or the third agent among the first to third agents, the hair bleaching performance can be further improved.

When the volatile hydrocarbon is used in the form of a composition, the blending amount thereof is not particularly limited, and can be appropriately blended according to the form of use, the decolorization promoting performance, and the like. The blending amount of the volatile hydrocarbon may be 0.1% by mass or more, 0.5% by mass or more, 1.0% by mass or more, or 1.5% by mass or more with respect to the total amount of the composition. .. The upper limit of the blending amount of the volatile hydrocarbon is not particularly limited, but such a composition can be used as a first agent or a first agent used in, for example, a two-agent or three-agent hair bleaching or hair dyeing kit. When used as a second agent, it can be 20% by mass or less, 15% by mass or less, or 10% by mass or less with respect to the total amount of the composition, and 7% by mass from the viewpoint of promoting hair bleaching. The following is preferable, and 5% by mass or less is more preferable.

The third agent used in the three-agent hair bleaching or hair dyeing kit is an agent for imparting additional performance, and is typically appropriately mixed with the first agent and / or the second agent. Used together. Therefore, the blending amount of the volatile hydrocarbon with respect to such a third agent is not particularly limited because it can vary depending on the purpose of use of the third agent and the like. For example, the third agent may be composed of only volatile hydrocarbons, or may be composed of a composition in which volatile hydrocarbons are used in combination with an oil component that moisturizes the hair. In the case of the composition, the blending amount of the volatile hydrocarbon is 0.1% by mass or more, 0.5% by mass or more, 1.0% by mass or more, or 1.5% by mass or more with respect to the total amount of the composition. 90% by mass or less, 80% by mass or less, 70% by mass or less, 60% by mass or less, 50% by mass or less, 40% by mass or less, 30% by mass or less, 20% by mass or less, 15% by mass or less, Alternatively, it can be 10% by mass or less.

In the case of the three-agent type, for example, the first agent to the third agent can be mixed and carried out in the same manner.

Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto. Hereinafter, unless otherwise specified, the blending amount is shown in% by mass.

<< Examples 1 to 6 and Comparative Examples 1 to 17 >>
The first agent (composition containing an alkaline agent) of the two-agent decolorizing agent of each formulation shown in Tables 2 to 6 was prepared by a conventional method. In addition, a second agent (composition containing an oxidizing agent) of the two-agent decolorizing agent of the formulation shown in the formulation example of Table 1 below was prepared by a conventional method. The following evaluations were made using these first and second agents, and the results are shown in Tables 2 to 6 and FIGS. 1 to 3.

<Evaluation method 1>
(Decolorization promotion evaluation 1: L value)
A mixture prepared by uniformly mixing 1.5 g of the first agent and 1.5 g of the second agent was applied to 1 g of black hair strands with a brush, left in an incubator at 31 ° C. for 30 minutes, and then. Thoroughly washed with water and dried with a dryer to prepare an evaluation sample. The L value of the prepared evaluation sample was evaluated using a color difference meter (CM-3600d, manufactured by Konica Minolta Co., Ltd.).

<Prescription of the second agent of the two-agent depigmenting agent>

<Prescription and evaluation results of the first agent of the two-agent depigmenting agent>
The formulation of Example 1 in Table 2 is the same as the formulation of Comparative Example 1 except that a volatile hydrocarbon was added. Further, the formulations of Examples 2 to 6 in Table 3 are the same as the formulations of Comparative Example 2 except that volatile hydrocarbons are added, and the formulations of Comparative Examples 3 to 7 in Table 4 are further added with liquid paraffin. The formulations of Comparative Examples 8 to 12 in Table 5 are the same as the formulations of Comparative Example 2 except that the cyclic silicone was added, and the formulations of Comparative Examples 8 to 12 in Table 5 are the same as those of Comparative Example 2 except that they were added. The formulations of 13 to 17 are the same as the formulations of Comparative Example 2 except that the linear silicone was added.

<result>
As is clear from Tables 2 to 3 and FIGS. 1 to 2, volatile hydrocarbons having 12 carbon atoms as compared with the L values of Comparative Examples 1 and 2 having a configuration not containing volatile hydrocarbons. Since the L value of Examples 1 to 6 of the configuration containing isododecane, which is hydrogen, is clearly higher, the use of a specific hydrocarbon has the ability to promote hair bleaching. I was able to confirm that.

The L value of Example 1 was 19.6, which was less than 20.0, while the L value of Examples 2 to 6 was more than 22.0. The cause of this is considered to be the morphology of the composition. That is, the creamy compositions of Examples 2 to 6 are more likely to be retained by the hair than the liquid composition of Example 1, and the alkaline agent and the oxidizing agent are deeper inside the hair than usual. It is considered that the cause is that it penetrated and decomposed melanin.

Further, as is clear from the results of Tables 4 to 6 and FIGS. 3 (a) to 3 (c), liquid paraffin, volatile cyclic silicone, and volatile direct, which are different from volatile hydrocarbons. It was found that chain silicone and the like could not exhibit the ability to promote hair bleaching. On the contrary, since the L value of Comparative Example 3 to Comparative Example 17 having a configuration containing these components is lower than the L value of Comparative Example 2 having a configuration not containing these components, liquid paraffin and volatility It can be said that the use of volatile cyclic silicone and volatile linear silicone has the ability to reduce the bleaching of hair.

<< Examples 7 to 15 and Comparative Examples 18 to 26 >>
The first agent (composition containing an alkaline agent) of the two-agent decolorizing agent of each formulation shown in Tables 7 to 8 was prepared by a conventional method. In addition, a second agent (composition containing an oxidizing agent) of the two-agent decolorizing agent of the formulation shown in the formulation example of Table 1 above was prepared by a conventional method. The following evaluations were made using these first and second agents, and the results are shown in Tables 7 to 8.

<Evaluation method 2>
(Decolorization promotion evaluation 2: visual observation)
A mixture prepared by uniformly mixing 1.5 g of the first agent and 1.5 g of the second agent was applied to 1 g of black hair strands with a brush, left in an incubator at 31 ° C. for 30 minutes, and then. The reference sample and the evaluation sample were prepared by washing thoroughly with water and drying with a dryer. Here, the "reference sample" is intended as a sample prepared by using the composition of Comparative Example 2 described above containing no volatile hydrocarbon as the first agent, and the "evaluation sample" is referred to as Table 7 and Samples prepared using the compositions of Comparative Examples 18-26 and Examples 7-15 in Table 8 as the first agent are intended.

The prepared reference sample and evaluation sample were visually observed, and the decolorization promoting property was evaluated according to the following criteria. Here, the A and B evaluations can be regarded as passing, and the C evaluation can be regarded as failing:
A: The evaluation sample was much brighter than the reference sample.
B: The evaluation sample was brighter than the reference sample.
C: There was no difference in brightness between the reference sample and the evaluation sample.
