| 摘 要： | 目的：研制防晒霜乳膏，观察该乳膏对紫外线的防护效果。方法：以UV－B，UV－A为防晒剂，制备防晒霜乳膏；以透气胶带为角质层，紫外分光光度计为光源，测定防晒效果。结果：UV－B防晒剂对280，290，300，310，320nm5个波长的吸光度分别为A280＝1．9，A290＝2．3，A300＝2．7，A310＝3．7，A320＝2．9。吸光度A值随波长的改变而改变。结论：防晒霜具有完全防护紫外线效果。

| Abstract: | Objective: To prepare and observe sunscreen effect against ultraviolet ray of the Sunscreen Cream. Methods: Prepare Sunscreen Cream by sunscreen agent, determine sunscreen effect by diathermanous tape and spectrophotometry meter. Results: Five wave length absorption coefficieat were A 280 =1.9, A 290 =2.3, A 300 =2.7, A 310 =3.7, A 320 =2.9 of UV B sunscreen agent, absorption coefficient changed with wave length. Conclusion: The Sunscreen Cream has completely defense effect to ultraviolet ray. |
