Description

  The present invention relates to a hair cosmetic.

  In hair cosmetics, an anionic surfactant permeates moisture into hair and imparts moisture. In addition, the cationic surfactant imparts smoothness and softness to the hair and improves the feeling of touch and combing.

  However, when an anionic surfactant and a cationic surfactant are used together and emulsified, a complex is formed in the composition, resulting in lumps and lumps, which cannot be uniformly emulsified, and the emulsion is stable. There is a problem of inferiority. In addition, since roughness or the like occurs, there is a problem that the feeling of use is inferior. Therefore, it has been very difficult to formulate an emulsion using an anionic surfactant and a cationic surfactant in combination from the viewpoint of emulsion stability and feeling of use.

  Up to now, as an attempt to impart stability of the preparation, a hair cleansing composition containing a specific anionic surfactant, a specific water-soluble polymer, a nonionic surfactant, a silicone compound and a cationic surfactant Product (for example, see Patent Document 1), a specific anionic surfactant, a specific cationic surfactant, a specific alcohol, and a specific copolymer and a hair cleanser composition (for example, see Patent Document 2) ) Etc. have been proposed.

  However, these trials can provide stability to the formulation, but are highly dependent on other components such as specific water-soluble polymers and specific alcohols, resulting in poor use feeling and limited use. There is a problem of being.

  On the other hand, as described above, when an anionic surfactant and a cationic surfactant are used in combination to form a transparent cosmetic, there is a problem that precipitates and lumps are generated and become cloudy and not transparent. is there. Moreover, even if it can be made transparent, it has been difficult to maintain transparency over time.

  Until now, attempts have been made to use an anionic surfactant and a cationic surfactant in combination in transparent cosmetics. For example, a transparent hair rinse composition containing a monoalkyl type quaternary ammonium type cationic surfactant, a carboxylate type anionic surfactant, and specific alcohols (see, for example, Patent Document 3), A transparent hair conditioning composition containing a cationic surfactant and a highly alkoxylated anionic surfactant (see, for example, Patent Document 4) has been proposed.

However, although these attempts can temporarily suppress the formation of complexes in the composition, problems such as precipitates and lumps being formed over time, resulting in poor stability of the preparation, and transparency persistence. There is a problem of being inferior.
