Description

  The present invention relates to a hair cosmetic that has excellent conditioning properties and suppresses itching and inflammation of the background.

  In recent years, women's hair has become more susceptible to physical damage due to daily hair washing, styling, hair dryers, and the like, and chemical damage due to hair dyeing, bleaching, perm treatment, and the like, with an increasing awareness of cleanliness and fashion. Problems with damaged hair include a feeling of squeezing when shampooing is rinsed, hair dryness after drying, deterioration of smoothness, deterioration of combing and the like. On the other hand, it is an important function of hair cosmetics to exhibit an excellent conditioning effect, to keep the skin healthy and to prevent itching inflammation.

Conventionally, in order to improve the problem of hair loss and smoothness deterioration, hair cosmetics containing a gallic acid derivative, a cationic surfactant, and a higher alcohol (see Patent Document 1: JP-A-2004-210724), A hair cosmetic containing an α-hydroxy acid and a gallic acid derivative (Patent Document 2: Japanese Patent Application Laid-Open No. 2005-179198) has been proposed. However, in the said hair cosmetics, the effect which does not cause inflammation on the ground and does not cause itching in long-term use was not fully examined.

On the other hand, in order to prevent and reduce scalp dandruff and itching, hydroxypyridone compounds,
It is known that bactericides such as pyrithione compounds, miconazole and salts thereof, and sulfur are blended in hair cosmetics as anti-dandruff / itch prevention agents (Patent Document 3: JP-A-54-98343). Patent Document 4: Japanese Patent Application Laid-Open No. 11-269043). However, these hair cosmetics are not sufficiently effective for conditioning properties, and there is a concern about irritation to the scalp by using a bactericide. Further, since there are people who feel itching due to the use of preservatives such as parabens, a hair cosmetic that reduces the amount of such preservatives and suppresses itching and inflammation of the skin has been desired. In addition, the following is mentioned as a prior art document.
