Description

  The present invention relates to a hair cosmetic, and more particularly, not only healthy hair but also hair damaged by hair color, perm, ultraviolet rays, etc., is excellent in spreadability when applied to hair, and at the time of rinsing The present invention relates to a hair cosmetic composition that has a smooth and profound feeling of use without tangling or squeezing hair, and having an excellent finished feeling after drying.

  For the purpose of imparting flexibility and wettability to the hair, protecting the hair and improving the touch, hair cosmetics of the type used by washing away such as rinses, conditioners and treatments are widely used. In recent years, consumers have become more aware of damage due to an increase in the hair color and perm population, and these rinse treatments not only provide a good finish after drying, but also entangle the hair during use. There is a growing demand for a smooth and profound feeling of use without being cramped. Rinse treatments often form a gel-like structure with a cationic surfactant, a higher alcohol, and water, thereby imparting a smoothness between application and rinsing, that is, a so-called rinse feeling. Conventionally, in producing these rinse treatments, it has been common to emulsify at a temperature higher than the melting point of the cationic surfactant or higher alcohol (for example, see Patent Documents 1 and 2). There is a limit to the rinsing feeling that can be obtained using this method, especially the smoothness and profound feeling during rinsing, and is particularly satisfactory for hair damaged by hair color, perm, ultraviolet rays, etc. It was not a thing.
