Description

The present invention relates to a first agent composition for hair dyeing or bleaching. More specifically, it is a first part composition for hair dyeing or bleaching that is used by mixing with a second part composition for hair dyeing or bleaching before use, which shows little change in viscosity even when stored at low temperatures, and can be easily removed from a container. The present invention relates to a first agent composition for hair dyeing or bleaching that does not affect the discharge properties of hair.

With the rise in fashion consciousness in recent years, hair coloring agents that allow you to easily change your hair color have become popular among both men and women. There are various types of hair coloring agents, such as permanent hair dyes, semi-permanent hair dyes, bleaching agents, and temporary coloring agents, which are used depending on each need. Among them, permanent hair dyes and bleaching agents have excellent hair dyeing and bleaching effects, and are hair coloring agents that are currently used by many people due to this property.

Permanent hair dyes and bleaching agents include a first part composition containing an alkaline agent and a second part composition containing an oxidizing agent such as hydrogen peroxide, which may or may not contain an oxidizing dye. Formulas are widely used. These can be applied by mixing the first part composition and second part composition for hair dyeing or bleaching in a tray or bottle-shaped container immediately before use, and then applying the mixture onto the hair, or by using a brush, etc. There are methods such as mixing on the hair.

The first and second agent compositions for hair dyeing or bleaching should be kept in various containers (polymer containers, aluminum tube containers, polytube containers) until they are used, as the alkali agent and oxidizing agent cause an oxidation-reduction reaction when mixed. containers, aerosol containers, pouch containers, etc.). Therefore, the viscosity of the first part composition and the second part composition for hair dyeing or bleaching is appropriately set in consideration of dischargeability from the container. In the case of emulsion compositions, higher alcohols having 12 to 24 carbon atoms are often used to adjust the viscosity, and higher alcohols also have the effect of increasing emulsion stability. Several first agent compositions for hair dyeing or bleaching have been disclosed so far (Patent Document 1 and Patent Document 2).

By the way, the general room temperature when using air conditioning equipment is around 20°C, but in the middle of winter when heating equipment is not used, the room temperature can drop to 5°C (meaning low temperature in the present invention). Therefore, the first agent composition for hair dyeing or bleaching may be stored for a long period of time under such an environment.

As described above, the first part composition for hair dyeing or bleaching contains a higher alcohol having 12 to 24 carbon atoms from the viewpoint of viscosity adjustment and emulsion stability. However, the crystallization of higher alcohols having 12 to 24 carbon atoms is promoted in low-temperature environments, and the viscosity of the emulsified composition increases over time. (including co-discharging properties with the second decolorizing agent composition). Therefore, there is a need for a first part composition for hair dyeing or bleaching that has little change in viscosity even when stored at low temperatures and does not affect dischargeability from a container.

However, none of the patent documents considers the dischargeability from the container during low-temperature storage.

The present invention has been made in view of the above problems, and is a first part composition for hair dyeing or bleaching, which is used by mixing with a second part composition for hair dyeing or bleaching, at the time of use.

EXAMPLES Hereinafter, the present invention will be explained in more detail with reference to Examples, but the present invention is not limited only to these Examples.

The evaluation test shown in this specification was conducted while changing the components and contents contained in the first agent composition for hair dyeing or bleaching. All units indicating the content of each component are mass %, and were prepared by a conventional method.

<Change in dischargeability from container during low temperature storage>
In the evaluation test related to "change in ejectability from a container during low-temperature storage" shown in this specification, the first agent composition for hair dyeing or bleaching, prepared by a conventional method, was placed in an aluminum tube ( Manufactured by Takeuchi Press Kogyo Co., Ltd., outer diameter: 25.2 mm, inner diameter: 24.5 mm, under-shoulder dimension: 130 mm, diameter: 6.7 mm both length and width, inner surface coat: TPL-418, lining agent: 40 g filled in Hi-Lap K). After that, the first part composition for hair dyeing or bleaching stored at 5°C for 30 days and the first part composition for hair dyeing or bleaching stored for 30 days at 20°C were placed in aluminum tubes. The difference in ejectability of the first agent composition for hair dyeing or bleaching at storage temperatures of 5°C and 20°C was determined by 10 panelists as follows: The evaluation criteria were as follows, and the total score was used as the evaluation result.

<Evaluation criteria for changes in dischargeability from containers during low-temperature storage>
No difference in discharge performance between 5°C and 20°C: 3 points Slight difference in discharge performance between 5°C and 20°C: 2 points No difference in discharge performance between 5°C and 20°C: 1 point

<Evaluation results of changes in dischargeability from containers during low-temperature storage>
◎: 25 points to 30 points 〇: 21 points to 25 points △: 16 points to 20 points ×: 10 points to 15 points

In Examples 1 to 12 in Table 1, even if the type and content of the component (A) and the component (B) were changed, compared to Comparative Examples 1 to 3, the results showed that the results showed that the results were not as high when stored at low temperatures as compared to Comparative Examples 1 to 3. Also, results were obtained in which there was little change in viscosity and there was no effect on discharge performance from the container.

In Examples 13 to 20 in Table 2, even if the type and content of the component (C) were changed, compared to Comparative Example 4, there was less change in viscosity even during low-temperature storage, and the dischargeability from the container was lower. The results showed that there was no effect on

The present invention is a first part composition for hair dyeing or bleaching that is used by mixing with a second part composition for hair dyeing or bleaching before use, which shows little change in viscosity even when stored at low temperatures, and can be easily removed from a container. It is possible to provide a first agent composition for hair dyeing or bleaching that does not affect the discharge properties of hair.
