Description

  The present invention relates to a hair cosmetic that has good slipperiness and cohesiveness of hair, and has a sharp feeling.

Hair cosmetics are required to have a higher level of slipperiness, moistness and coherence due to increased hair damage due to chemical treatments such as perm, bleach and coloring. In addition, there are many problems caused by the low elasticity of hair, such as no hair, no stiffness, and no volume.
Because of these requirements, quaternary ammonium salts such as stearyltrimethylammonium chloride, behenyltrimethylammonium chloride, and distearyldimethylammonium chloride are used as cationic surfactants. However, hair that always satisfies these requirements is used. Cosmetics are not obtained. In addition to cationic surfactants, combinations with silicones and fats and oils are known as additives. When these additives are used, the stability of the system is affected, so that there is a problem that adjustment of the blending amount is necessary or hair stickiness occurs.

In Patent Documents 1 and 2, a specific ether type quaternary ammonium salt is introduced in order to improve the slipperiness and cohesiveness of the hair, but it cannot satisfy the harshness at the same time.
Patent Document 3 discloses a method using a specific aromatic organic acid in order to improve the moist feeling, but sufficient slipperiness is not obtained, and slipperiness and cohesiveness with respect to hair are not obtained. The moist and firm feeling was not satisfactory at the same time.
