System for measuring the water resistance SPF of sunscreen agent by in vitro and the method for measuring the in vitro water resistance SPF of sunscreen agent by using the same

摘要

The present invention is in of sunscreen vitro water resistance (water resistance) SPF SPF relates to the measurement method using the measurement system and this. More specifically, according to the present invention in vitro water resistance SPF measurement system is attached to the substrate (substrate) coated with a sunscreen on the rotary blades in the rotary blade substrate in the bath itself rotates a system that is rotated sunscreen so I washed in water , which is in vivo , so the water resistance SPF measure accurately reproduce the actual clinical trials testing the water resistance without sunscreen in vitro is to be measured on .
