Description

The present invention relates to a hair dye first agent composition. More specifically, the present invention relates to a first hair dye composition having excellent hair dyeability and excellent in long-term stability over time at high temperatures and stability over time at high temperatures.

With the recent rise in fashion awareness, hair coloring agents that can easily change the color of hair are accepted by many people regardless of gender. There are various types of hair coloring agents, such as permanent hair dyes, semi-permanent hair dyes, decolorizing agents, temporary coloring agents, etc., which are used according to the respective needs. Among them, permanent hair dyes are excellent in the persistence of the hair coloring effect, and are the most popular hair coloring agents currently used by many people because of this property.

As permanent hair dye, a two-component formula consisting of a first agent composition for hair containing an oxidation dye and an alkali agent and a second agent composition for hair containing an oxidant such as hydrogen peroxide is widely used. It's being used. Although the alkaline agent contained in the first agent composition for hair dyeing is an essential component for decolorization and dyeing, it may cause a reduction in feel of the hair such as squeak.

Therefore, oil-based components such as hydrocarbons, higher alcohols and silicone oils are contained in the first agent composition for hair dyeing for the purpose of improving the feel of hair and the like. These oil components are contained in the first agent composition for hair coloring as an emulsion by being contained together with an emulsifier such as a surfactant. However, since the first dye composition for hair dyeing contains an oxidation dye, its temporal stability tends to be lower than ordinary emulsions. In addition, there is a possibility of being put under severe environment during transportation or storage, especially in summer, it may be about 60 ° C in containers used for transportation to overseas due to the influence of air temperature and reflection heat. In such a high temperature environment, coalescence and creaming are promoted and it is easy to cause separation.

Various attempts have been made to solve these problems. For example, Patent Document 1 below contains an anionic surfactant and a polyhydric alcohol for the purpose of improving the stability and feel of the hair dye composition, and substantially comprises a nonionic surfactant and a cationic surfactant. A hair dye composition that does not contain an agent and an amphoteric surfactant is disclosed.

Patent Document 2 below discloses a hair dye composition containing an alkanolamine, a higher alcohol and a quaternary ammonium type cationic surfactant for the purpose of improving the hair dyeability and the feel.

Patent Document 3 below discloses a first composition for hair coloring containing silicone oil, higher alcohol, nonionic surfactant, cationic surfactant, higher fatty acid and water for the purpose of improving high temperature stability and feeling. Is disclosed.

Unexamined-Japanese-Patent No. 2003-171247 JP 2004-189717 A JP, 2016-121104, A

The first agent composition for hair dyeing of Patent Document 1 improves the temporal stability at high temperature by containing an anionic surfactant and a polyhydric alcohol such as glycerin or propylene glycol. However, the penetration of the dye into the hair is inhibited by the polyhydric alcohol, which may reduce the hair dyeing effect.

The first agent composition for hair dyeing of Patent Document 2 described above is good by using an alkanolamine as an alkaline agent and setting the ratio of the higher alcohol to the quaternary ammonium type cationic surfactant within a specific range. Although the hair dyeing effect and the improvement of the feel of the hair were achieved, the stability over time at high temperature by the hair dye containing silicone oil is not disclosed.

The first agent composition for hair dyeing of Patent Document 3 contains silicone oil, a higher alcohol, a nonionic surfactant, a cationic surfactant, a higher fatty acid and water to improve the high-temperature stability over time. And improve the feel of the hair after treatment. However, when the higher fatty acid is contained, the odor derived from the fatty acid is generated with the passage of time, which tends to cause the user to feel an unpleasant odor at the time of use.

Therefore, the present invention is made in view of the above problems, and has a good hair dyeability, a first agent composition for hair dyeing excellent in long-term stability over time at high temperature and stability over time at high temperature Intended to provide.

The present inventors make the first agent composition for hair dyeing contain a higher alcohol, a nonionic surfactant and a cationic surfactant which are solid at 25 ° C., and a higher alcohol which is solid at 25 ° C., a nonionic surfactant It is found that the above problems are solved by adjusting the content ratio of the agent and the cationic surfactant, and the content ratio of the nonionic surfactant and the cationic surfactant to a specific range, and the present invention is completed.
