Description

  The present invention is a hair cosmetic containing a diol derivative, which can impart good slippery immediately after application to the hair, and shows good passage from a wet state to a dry state. It is related with the hair cosmetics which can suppress the stickiness of hair, can give slipperiness and luster, and can protect hair from mechanical irritation.

  In recent years, with the trend of coloring and permanents, hair damage has increased due to chemical treatments such as hair color and permanent wave, and physical treatments such as friction by brushing and drying with a dryer. Problems such as incoherence, loss of gloss, and poor fingering have occurred. Therefore, in both the wet and dry scenes of hair, it is required to impart good slipperiness to the hair and to protect the hair from mechanical friction such as brushing to prevent damage.

  As described above, in order to protect hair from mechanical friction and to give slipperiness after drying, generally, a method of blending various oils into hair cosmetics is used. However, in order to give sufficient smoothness to the hair, it is usually preferable to use a large amount of an oil agent. On the other hand, if the amount of the oil agent is increased, it does not adhere uniformly to the hair, causing stickiness and deterioration of gloss. was there. In particular, hair that has been damaged by coloring or permanent wave treatment contains a mixture of severely damaged hair ends and healthy roots. Tend to be sticky.

  Therefore, hair cosmetics containing specific diol derivatives have been proposed in order to protect hair while suppressing stickiness (see, for example, Patent Document 1 and Patent Document 2). However, in damaged hair, it is easy to feel the squeaky feeling of the hair and the weight of the fingers during the treatment, while eliminating the squeaky feeling of the severely damaged hair tips and the weight of the fingers. It was not sufficient to protect and impart slipperiness.
