CONSTITUTION:A slightly water-soluble cosmetic component (e.g., natural animal or vegetable fats and oils such as olive oil, mink oil, jujube oil, lanolin, hydrocarbon such as liquid paraffin, squalane, etc., wax such as whale wax, bees wax, etc., higher alcohol such as cetanol, etc., higher fatty acid, etc. such as myristic acid, etc., silicone oil, etc.) is blended with a cyclodextrin polymer [having >=20 water-solubility in 100ml water at 25 deg.C; preferably compound shown by the formula (n is 3-4)] in the form of an inclusion compound of it and the cyclodextrin polymer, to give a cosmetic for the skin wherein a large amount of the slightly water-soluble cosmetic component is uniformly blended. The amount of the cosmetic component used is 0.001-0.5pt.wt. based on 1pt.wt. cyclodextrin polymer and the treatment temperature is 10-70 deg.C. |
