each formulated product was applied to the skin separately and after waiting to dry completely, each item was scored by an evaluation panel consisting of trained cosmetic technicians, with a minimum score of 1 being the worst and a maximum score of 5 being the best. Since the scores are relative, there is no comparability between the scores of the respective groups.
For the "leave-on" experiment, the skin was subjected to a standardized washing procedure. The skin softened in water for 15 minutes was rinsed for 2 minutes by washing the skin with a 12 wt% sodium lauryl sulfate solution, rinsed thoroughly with warm water, and blown dry on a cold air screen.
A sample of foundation was applied in the area of 2X2cm, and the "foundation evaluation" experiment was performed in a special climate laboratory with a relative humidity of > 60%. The temperature of the chamber was 25 ℃. Testing conditions, smearing feeling, smearing 2min after smearing, and feeling evaluation 10min after smearing.
