摘要： PURPOSE: To obtain the subject cosmetic excellent in water resistance and presenting no oily feeling. CONSTITUTION: This W/O-type makeup cosmetic is obtained by mixing water with an oily base prepared by forcedly dispersing at least one kind of fine powder having 5-350nm primary particle diameter essentially comprising white powder and colored powder in a solvent containing volatile silicone and/or light liquid paraffin. The amount of the fine powder to be used is pref. 3-60 (esp. 5-40) pts.wt. based on 100 pts.wt. of the oily base, pref. accounting for 15-100 (esp. 50-100)wt.% of the whole powder. It is preferable that the mixing weight ratio of the oily base to water be (20:80) to (90:10) and the mixing means be a wet medium-type mill or a pulverizing apparatus typified by a homogenizer.

摘要： PURPOSE:To provide the subject cosmetic by mixing and dispersing water into water-repellent powder to obtain a structure containing fine water-droplets dispersed in the powder and adding an oil to the dispersion to get excellent applicability and cool and refreshing feeling. CONSTITUTION:A powdery material (e.g. yellow iron oxide and fine powder of titanium oxide) is coated with a water-repellent agent (e.g. methylhydrogen polysiloxane) using an air-flow dryer or spray dryer and the coated powdery material is heat-treated to obtain water-repellent powder. The objective W/O- type make-up cosmetic can be prepared by compounding 93-40wt.% of the water- repellent powder with 5-40wt.% of water and 2-20wt.% of an oil (e.g. oleic acid, liquid paraffin or squalane). The water-repellent powder is preferably coated with an oil containing Si-H group such as silicone oil and methylsilicone oil. The cosmetic has excellent applicability (spreadability, adhesivity, refreshing feeling and durability) and suitable as a foundation for summer season.

摘要： PROBLEM TO BE SOLVED: To provide a method for reinforcing a UV light-protecting ability to suppress the damages to the skin with the UV light, to prepare a cosmetic utilizing the method, and to provide a making-up method characterized by applying the above method to prevent the outbreak of skin inflammation.
SOLUTION: This method for reinforcing the UV light-protecting ability is characterized by coating the skin with a self-tanning agent not containing lawsone and tryptophan to color the skin, before exposing the skin on UV light, thereby reinforcing the resistance of the skin to UV light. A combined cosmetic is characterized by storing the self-tanning agent and a sunscreen agent having a UV light-protecting effect represented by an SPF of ≥10 in a set box. The making-up method is characterized by using the self-tanning agent for one day or more and then using the sunscreen agent having the UV light-protecting effect represented by the SPF of ≥10 before exposing the skin on UV light, thereby reinforcing the resistance of the skin to UV light.
