Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pearly luster composition which has an excellent feeling of use and conditioning effect on hair and the like, an excellent pearl luster, and an excellent dispersion stability. is there.

[0002]

2. Description of the Related Art With the recent increase in consumers' awareness of hair care, the demand for hair care products has been diversified.
In such products, not only the cleansing and foaming properties of shampoo and the finished feeling of rinse treatment,
It is required to have good spreadability to hair during application, easy adaptability to the hair, good finger passage, and good usability such that the hair does not come off during rinsing. In addition, not only usability but also many voices demanding beauty in appearance and high quality, it has been attempted to give a beautiful pearl luster to such a request.

Conventionally, high molecular weight dimethylpolysiloxane and the like have been widely used as conditioning agents in shampoos and rinses in order to obtain an excellent feeling of finish. However, when the high-molecular-weight dimethylpolysiloxane was added to a system using water as a dispersion medium, there was a problem in the dispersion stability. As measures against this, a method using xanthan gum (JP-A-61-210022), a method using a long-chain acyl derivative or the like (JP-A-1-13013), and a method using a fatty acid alkanolamide (JP-A-3-213) No. 135909) has been proposed. However, in the method using xanthan gum, the spreadability at the time of application and the finger passage at the time of use are not sufficient, and in the method using the fatty acid alkanolamide, the fatty acid alkanolamide is blended in an amount of 5 to 80% by weight (hereinafter, simply abbreviated as%). It was necessary and had a drawback that it had a peculiar squeaky feeling at the time of rinsing. According to this method, when the amount of the fatty acid alkanolamide was less than 5%, the squeaky feeling was eliminated, but the high molecular weight dimethylpolysiloxane could not be stably dispersed, and the desired effect could not be obtained. In addition, the compositions obtained by these methods became cloudy and were inferior in appearance. Addition of a pearly brightener to them satisfies the appearance aesthetics but cannot solve the drawbacks in use. On the other hand, although a pearly luster can be obtained by the method using the above long-chain acyl derivative or the like, it is not preferable in terms of spreadability at the time of application and ease of fitting to hair. Thus, a pearly luster composition having an excellent feeling of use and conditioning effect on hair and the like, an excellent dispersion stability and an excellent pearly luster has not yet been developed.

[0004]
