乳液劑型牽涉到油水比例和使用的乳化劑是一個很複雜的物理化學過程，粒徑及粒徑分佈的不同將直接影響乳液産品的性能，所以探討不同的攪拌形式及強度對粒子大小影響是一個很重要課題。本研究利用蜂蠟作為分散相，去離子水為連續相，添加GMS及Arlacel 165乳化劑作用下，分別研究不同攪拌形式（手工機器）、攪拌設備（高力攪拌機或約質乳化機）及攪拌強度（2000rpm/min與8000rpm/min）對乳液粒徑大小之分佈影響。利用兩種在化粧品上最常用的粒徑量測方法：光繞射法及顯微鏡量測法。研究結果發現，利用手工攪拌之乳液平約粒程大小為54.57μm，高力攪拌機之平均粒程大小為7.87μm，約質乳化機之平均粒極為5.69μm；另外在均質乳化機攪拌條件下以較高轉速(8000rpm/min)可以得到較小粒徑。

Influences of the amount of stirring condition on the particle size were studied under the conditions of beeswax as dispersed phase, deionized water as continuous phase, and GMS with Arlacel 165 as emulsifier. In the above emulsion unit with two common methods of measuring the diameter of emulsion-particles: X-ray diffraction and microscope. The results showed that the best stirring effect was obtained with machinery equipment type agitator at same emulsion formula, and that the average particle size obtained at manual, stirring machine (rotating rate as 2000 rpm/min) and homogenizer (rotating rate as 8000 rpm/mm) at 54.57 μm, 7.87μm and 5.69 μm, respectively.
