[0002]

2. Description of the Related Art Hair treatment agents having a so-called rinsing effect of imparting softness and gloss to hair and improving combability are commercially available under the names of hair conditioner, hair treatment, hair rinse and the like.

It is known to incorporate solid oils into these hair treatment agents. In particular, higher alcohol of solid oil content,
It is blended in a large number of rinse-out hair conditioners because it gives a rinsing effect such as a smooth feeling, easily forms a gel with a cationic active agent, and can be blended at low cost.

[0004] In addition to higher alcohols, microcrystalline wax, solid paraffin, carnauba wax, fatty acids and the like have sometimes been blended mainly to give the hair a sense of unity after drying.

With regard to hair treatment agents, general consumers are demanding not only the feeling of rinsing and after drying, but also the viscosity of the liquid when taken out, that is, the rich feeling. Was.

[0006] However, it is very difficult with the conventional technique to satisfy both the feeling after drying and the rich feeling when put on the hand. In particular, if the viscosity of the liquid is increased to give a rich feeling, it has been negative in terms of ease of taking out from the bottle and adaptability during application.

[0007] In order to solve these problems, various solid oils have been studied, but it has been extremely difficult to simultaneously satisfy the smoothness at the time of rinsing.

The present inventors have conducted intensive studies from the above-mentioned viewpoints, and as a result, have found that the above problems can be solved by blending a higher fatty acid having a hydroxyl group in a side chain in a hair treatment agent. In addition, it has been found that when a higher alcohol, an amidoamine derivative and a quaternary ammonium salt are blended, more excellent usability can be imparted.
