Description

  The present invention relates to a multi-component hair treatment agent comprising at least two agents of a first agent and a second agent that are sequentially applied to hair, and a hair treatment method using the treatment agent. The multi-component hair treatment agent of the present invention can be used as a hair rinse agent, a hair treatment agent or a hair conditioning agent.

  Daily shampoo treatment causes the oil necessary for the hair to be washed away more than necessary together with the dirt on the hair, or the hair is damaged by drying of the dryer, and the hair continues to be damaged every day. In addition, with recent spread of decolorization treatment, hair dyeing treatment, perm treatment, etc., hair damage is becoming more prominent. For example, due to a loss of smooth texture and an increase in patter, not only the flexibility and fingering of the hair deteriorate, but also it becomes easier to spread, and split ends and split hairs are more likely to be generated.

  In order to eliminate such hair damage, components such as cationic surfactants, cationic polymers, and silicone oils are usually added to hair treatment agents such as hair rinses, hair treatment agents, and hair conditioning agents. (For example, see Patent Documents 1 to 4).

  However, since many hair rinse agents, hair treatment agents, and hair conditioning agents are oil-in-water emulsions, oily components such as treatment components are in a state of being taken into water. Therefore, such a hair treatment agent has a problem that the oily component does not adhere sufficiently due to the difference in the surface state of the hair, and the effect of improving the flexibility, fingering, and feeling of touch of the hair cannot be sufficiently obtained. There is. In order to further enhance the effectiveness, it is possible to add an excessive amount of oily component, but by adsorbing the excessive oily component, it accumulates in the hair by continuing to use, excessive stickiness and hair itself There is also a problem that it leads to deterioration of the texture such as becoming hard.

  Therefore, as one of the attempts to improve the texture, a multi-drug hair treatment agent mainly composed of silicone oil and a multi-drug type that forms an anion / cation complex on the hair using the ionicity of the compounding ingredients. Hair treatment agents have been proposed.

  Specifically, a two-component hair treatment composition comprising a first agent containing a reducing substance and a cationic polymer and a second agent containing an anionic surfactant or amphoteric surfactant and an oil agent. (For example, see Patent Document 5), a first agent containing a quaternary ammonium salt type cationic surfactant, an amino-modified silicone, a dialkyl ether, and water, an acid, a polyhydric alcohol, and water. A multi-drug formula comprising a hair cosmetic comprising two agents (see, for example, Patent Document 6), a first agent containing amino-modified silicone, and a second agent containing an anionic surfactant and a cationic polymer. Hair treatment agents (see, for example, Patent Document 7) have been proposed.

  However, although these attempts can improve the adsorption to the hair and improve the texture, the excessive adsorption to the hair causes a sticky feeling, unnatural finish and inferior texture, washing off from the hair There is a problem that the feeling of inferior stickiness remains. In addition, the conventional attempts exhibit an excellent effect on the flexibility of the hair, but there is also a drawback that the hair is deprived and the entire hair is reduced in volume.

It turns out that it is excellent in the softness | flexibility of a hair immediately after, fingering property, and a touch feeling. In addition, when the first agent and the second agent are sequentially applied (Examples 1 to 10), when the application order of the first agent and the second agent is changed (Comparative Example 4), the first agent and the second agent Even when compared with the case of using a mixed solution of two agents (Comparative Examples 5 and 6), it can be seen that the above-described effects of the present invention are sufficiently exhibited.

  Surprisingly, Examples 1 to 10 give the hair a firmness and exhibit the effect of increasing the volume of the hair, whereas Comparative Examples 1 to 6 demonstrate the specific effects of the present invention. It can also be seen that it is not possible or has not been fully demonstrated.
