DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cleaning composition, and more particularly to a hair cleaning composition which prevents flaking during brushing, imparts excellent conditioning properties to hair, and has a good feeling of use. Composition.

[0002]

2. Description of the Related Art In recent years, the performance required for shampoos has been greatly changed with changes in lifestyles or changes in consumer awareness of shampoos. In other words, the shampoo that not only removes dirt on the hair and scalp but also gives the hair after washing and drying a moist and supple feel and gloss, and gives a good finish feeling with good combability. Is desired. Therefore, shampoos such as conditioning shampoos or rinse-in shampoos have been developed, and in order to improve conditioning and finish,
Quaternary nitrogen-containing water-soluble polymeric substances are widely used. Further, a combination of a cationic or amphoteric polymer substance and an anionic surfactant having a branched chain (Japanese Patent Laid-Open No.
No. 36224), and a combination of a cationic polymer substance and a gallic acid derivative (JP-A-4-74112). However, when these polymer substances, especially nitrogen-containing water-soluble polymer substances are added to the shampoo to impart conditioning property to the hair, these conditioning ingredients adhered to the hair are peeled off during brushing after the hair is dried, and flaking is caused. There is a problem of causing a phenomenon.

[0003]

Means for Solving the Problems The present inventors have made intensive studies to solve such problems, and surprisingly found that the compounding of a nitrogen-containing water-soluble polymer substance and a certain diol compound was not possible. It has been found that an excellent conditioning effect is imparted without causing flaking, and that the addition of a specific surfactant further improves this conditioning effect, thereby completing the present invention.
