BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition containing a long-chain hydrocarbon group-modified silicone compound, which has an excellent feeling of use and a long-lasting effect.

[0002]

2. Description of the Related Art Generally, cosmetics are mixed with oil for the purpose of preventing the skin from drying and protecting the hair surface. Depending on the nature of the oil, it may be sticky or oily when used. The disadvantage of occurs. In recent years, a refreshing and light feeling of use is preferred, and therefore, dimethyl silicone oil is blended for this reason. However, since dimethyl silico oil has poor compatibility with hydrocarbon oils, it is difficult to mix it with usual cosmetic ingredients, and it is easy to be washed off from the surface of the skin or hair, and the effect is difficult to last. It was

Therefore, a long-chain hydrocarbon group-modified silicone oil obtained by adding an α-olefin having 6 to 20 carbon atoms to polymethyl hydrogen siloxane has been studied (Japanese Patent Laid-Open No. 72095/1986). Same as 60-569

The compatibility was evaluated from the compatibility state of the components at the time of preparing the cosmetic. The number of samples was 10, and the average value was shown.

The stability is as follows:
It was evaluated by the separated state of the components after standing for one day. The number of samples was 10, and the average value was shown.
