Description

The present invention relates to a second agent composition for hair dyeing and bleaching. More specifically, it is a hair dyeing and bleaching second agent composition that is used by mixing with the hair dyeing and bleaching first agent composition at the time of use, and maintains good usability even at a high temperature. The present invention relates to a second agent composition for hair dyeing and bleaching, which has excellent stability over time at high temperatures.

Due to the growing awareness of fashion in recent years, hair coloring agents that can easily change the color of hair have been accepted by many people regardless of gender. There are various types of hair coloring agents such as permanent hair dyes, semi-permanent hair dyes, depigmenting agents and temporary coloring agents, and they are used according to their needs. Among them, permanent hair dyes and bleaching agents are excellent in hair dyeing and bleaching effects, and are hair coloring agents currently used by many people because of their characteristics.

As a permanent hair dye and depigmenting agent, it comprises a first agent composition containing or not containing an oxidation dye and containing an alkaline agent, and a second agent composition containing an oxidizing agent such as hydrogen peroxide. The formulation formula is widely used. Immediately before use, these are mixed on the hair with the first and second composition for hair dyeing and decolorization in advance in a tray or bottle-shaped container, and then applied on the hair or on the hair using a brush or the like. In any of these methods, it is required that the mixture does not drip or scatter during application, and several hair dyeing and decolorizing compositions have been proposed so far. (Patent Documents 1 to 3).

Generally, the dosage forms of the first agent composition and the second agent composition for hair dyeing and decolorization include creamy, milky liquid or gel form, and these are emulsified compositions with a surfactant or a polymer. , Solubilizing compositions and thickening compositions.

Further, the viscosities of the first agent composition and the second agent composition for two-agent hair dyeing and bleaching are appropriately set according to the dosage form, the method of use and the mixing method. Generally, from the viewpoint of mixing, the viscosities of the first agent composition for hair dyeing and bleaching and the second agent composition are often set to be about the same.

By the way, the hair coloring agent is desired to have various color tones depending on the needs of consumers. In the case of a two-agent permanent hair dye, the type and content of the oxidative dye and the alkaline agent in the first agent composition for hair dyeing differ depending on the color tone, and therefore the formulation differs for each color tone. On the other hand, since the second agent composition for hair dyeing uses a common composition regardless of the type of color tone, it is not necessary to prepare many prescriptions.

In addition, the mixing ratio of the first agent composition for hair dyeing and decolorization of the two-agent type and the second agent composition is 1: 1 or 1: 2, and the second agent composition is compared with the first agent composition. Often the same amount or more. Therefore, the viscosity of the mixture tends to depend on the viscosity of the second agent composition.

Therefore, if the second agent composition for hair dyeing and bleaching has good usability, the second agent composition for hair dyeing and bleaching has good usability even when combined with various first agent compositions for hair dyeing and bleaching. And it is easy to obtain a decolorizing composition.

When the hair dyeing and bleaching compositions are emulsified compositions, the higher the temperature of the emulsified composition, the lower the viscosity, which may cause dripping or splattering during use. The general room temperature when the air conditioner is used is around 20 ° C., but the room temperature when the air conditioner is not used in midsummer may reach 40 ° C. (meaning high temperature in the present invention). In addition, when stored in a warehouse or the like, it may be stored for a long time in a high temperature environment in the summer. In a high temperature environment, the emulsified composition promotes coalescence and creaming, and tends to cause separation. In particular, the second agent composition for hair dyeing and bleaching contains hydrogen peroxide and has a low pH, so that the stability over time tends to be lower than that of a general emulsified composition. Therefore, there is a need for a second agent composition for hair dyeing and decolorization that maintains good usability in the temperature range of 20 ° C. to 40 ° C. and has excellent stability over time at high temperatures.

However, in none of the patent documents, usability at high temperature and stability over time at high temperature were not considered.

We have found that the above problems can be solved by setting the viscosity ratio of viscosity: V (40 ° C.): V (40 ° C.) / V (20 ° C.) within a specific range, and have completed the present invention. ..

That is, the present invention is a hair dyeing and bleaching second agent composition used by mixing with the hair dyeing and bleaching first agent composition at the time of use, and has a viscosity at 20 ° C.: V (20 ° C.).
