摘要

本研究主要利用適量的界面活性劑所形成的乳液與美白成分－左旋維生素C磷酸鈉鹽(Sodium Ascorbyl phosphate, C-50)相互結合，透過改變乳液中的美白劑及抗氧化劑(Red wine polyphenol 1%, OPC Liquid)的比例不同，探討濃度改變對乳液的表面與界面性質的影響。在乳液的製備過程中有幾項因素需要列入考量，包括乳化劑中界面活性劑的比例、油水相的乳化溫度。美白乳液的分子構造以傅立葉轉換紅外光譜分析儀(Fourier Transform Infra Red Spectroscopy, FTIR)分析法確認。乳化液之基本性質測試則以表面張力(surface tension)接觸角(contact angle)及黏度等分析，另以偏光顯微鏡(Optical microscopy)觀察乳液的乳化穩定度。結果顯示只添加OPC 1%比添加OPC 1%與C50在表面張力、接觸角中，前者在稀釋1.0%時具有較良好的界面性質。

並列摘要

This research utilizes right amount active cream formed of pharmaceutical of interface and whitens the composition mainly - Left is it support the family plain C phosphoric acid sodium salt to fasten (Sodium Ascorbyl phosphate, C-50) mutually combine, different through changing the proportion of whitenning the pharmaceutical and antioxidant (Red wine polyphenol 1%, OPC Liquid) in the cream, probe into the thickness and change the impact on surface of the cream and interface nature. Several factors of preparation course of the cream need listing in and considering, including the emulsification temperature of the proportion of the active pharmaceutical of interface, profit looks in the emulsifier.
