Description

  The present invention relates to a hair cosmetic. More specifically, the present invention relates to a hair cosmetic that can impart a continuous natural luster without giving the hair a sticky, squeaky, or firm feeling.

  Since hair is subjected to various external environmental stresses such as cosmetic treatments such as shampoo, perm, hair color, drying with a dryer, etc., or ultraviolet rays, it often loses its original gloss. For this reason, in order to regain the original gloss of hair, there is a strong demand for hair cosmetics that can impart natural gloss to the hair.

  Conventionally, as means for imparting luster to hair, for example, hair cosmetics containing silicones (see, for example, Patent Documents 1 and 2) have been proposed. However, although it is possible to give gloss to the hair by such an attempt, the durability of the gloss is not satisfactory. On the other hand, there is a problem that a sticky feeling, a squeaky feeling, and a sticky feeling are generated when trying to maintain a continuous glossiness due to a high content of silicones. In addition, depending on the dosage form, there is a problem that white turbidity occurs and is not preferable in appearance.

  In addition, hair set polymers are generally blended with hair cosmetics in order to impart hair styling power and hair styling holding power. However, when an effective amount of the hair setting polymer is blended, the hair styling property and the hair styling retention force are excellent, but there is a problem that a sticky feeling, a squeaky feeling, and a feeling of firmness are generated. Furthermore, there is a problem that the formed film gives the hair an unnatural luster.

  As an attempt to impart natural luster to hair in a preparation containing a hair set polymer, for example, a hair cosmetic containing a hair set polymer, a cationic surfactant and silicone oil (see, for example, Patent Document 3) ), Hair cosmetics containing a hair set polymer, silicone oil, and polyhydric alcohol (see, for example, Patent Document 4).

  However, although natural luster can be imparted by such an attempt, the hair feels moist and the hair styling ability and hair styling holding power are reduced, and the durability of the imparted luster is inferior. There's a problem.
