2. Description of the Related Art Conventionally, for the purpose of removing stains on hair, the hair is washed with a shampoo containing an anionic surfactant as a main component. However, washing the hair with a shampoo not only stains the hair, but also protects the hair surface from oil. Are also removed at the same time,
The softness of the hair is lost, the hair becomes dull and dull, and hair damage, split ends, and broken hair are likely to occur. Therefore, for the purpose of imparting a conditioning effect (softness, moisturizing feel, dry feel, and slipperiness) to the hair, it is treated with a composition for hair containing a quaternary ammonium salt which is a cationic surfactant as a main component. When the composition for hair containing a quaternary ammonium salt as a main component is used, although the softness to hair is excellent, it may not be possible to obtain sufficient effects on moisturizing feeling, dry feeling, and slipperiness. Therefore, a composition containing an amide cation compound or the like, which has an excellent conditioning effect and gives a good feel even after drying, has been proposed. (JP-A-4-66520, JP-A-4-66520
-134022, JP-A-11-286415) and the fourth
Secondary ammonium salts can cause problems with irritation to the hair and scalp, and biodegradability.

[0003]

Therefore, the present invention is
Regarding a hair composition, it is an object of the present invention to develop a hair composition which is excellent in hair conditioning effect, is mild, mild to hair and scalp, and has good biodegradability.
