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., has good elongation and familiarity when applied to hair, The present invention relates to a hair cosmetic that imparts a feeling of unity and smoothness to the hair without feeling stiff.

Hair cosmetics such as rinses, conditioners and treatments are widely used for the purpose of imparting flexibility and wettability to the hair, protecting the hair and improving the touch. Recently, consumers are becoming more aware of damage due to an increase in the population of hair colors and perms, and these rinse treatments not only provide a good finish after drying, but also become more familiar when applied. However, there is a growing demand for a smooth feeling of use with no stickiness or stiffness. 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 above the phase transition temperature of the gel composition (for example, see Patent Document 1), but these methods were used. There is a limit to the rinsing feeling obtained in particular, the elongation at the time of application, the feeling of running-in, and the smoothness after drying, especially for hair damaged by hair color, perm, ultraviolet rays, etc. Was not satisfactory enough.
