Description
Summary:碩士 === 國立臺灣科技大學 === 高分子系 === 98 === In this study, natural materials (Angelica, aloe) on the tyrosinase activity inhibition effect and through with a water based polymer (chitosan, polyvinyl alcohol, PVP) characteristics, made with white, moisturizing, mild effect of the mask. Biochemical methods used in experiments in the Mason-Peterson method determination of tyrosinase activity inhibition effect, and the pH meter to test and observe the changes in pH, skin moisture meter measured changes in skin moisture content, drying moisture analyzer determination of drying rate, skin patch test solution for testing anaphylactic mask and explore the different components of the overall effect as a mask. The results showed that use of the natural extract raw materials, the inhibition of tyrosinase inhibition rate of Radix extract / aloe vera extract is better than back to borrowing from the combination / combination of aloe extract, and the water content and allergic skin measured results better. Modulation of the mask with the PVA solution tyrosinase activity inhibition rate determination is better than the solution with the PVP modulation mask. Are two kinds of combinations are allergic to the skin without causing irritation. Skin moisture content, formation time, drying rate, PVA solution portfolio mask than the combination of PVP solution obtained good results.
