Polyglyceryl Fatty Acid Esters를 이용한 안정한 W/D 에멀젼 제조
Preparation of Stable W/O Emulsion with Polyglyceryl Fatty Acid Esters
One of the popular formulations is W/O emulsion in cosmetics. W/O emulsions are usually light and silky skin feel water resistant, not sticky and not oily. But it is more difficult to develop stable W/O emulsions as the viscosity of W/O emulsions decreased as time went on. In this paper we tried to make stable W/O emulsions using polyglyceryl fatty acid esters. Polyglyceryl fatty acid Esters are very safe materials. In results, W/O emulsions using 2.0% polyglyceryl fatty acid esters are more stable than emulsions using silicon emulsifier. And in case of using 0.2%
glyceryl behenate/polyglycety1-6 octastearate by gelling agent in oil phase, manufactured more stable W/O emulsions and in case of using 0.05% xanthan gum by gelling agent in water phase, manufactured more stable W/O emulsions.
