Foamed emulsions are mixtures of oil, water and gas. Bubbles are surrounded by a continuous phase made of oil and water. The numerous interfaces can be stabilised using a single surfactant or mixtures of stabilisers. These systems are used to make a multitude of materials, which can be found in many products and processes from oil recovery to whipped creams. In this paper the different types of foamed emulsions encountered and the specific difficulties in their stabilisation are presented. Foamed emulsions with an aqueous continuous phase are the most commonly studied, and a more detailed description of their stability and mechanical properties is given.

混合气泡和液滴以制成泡沫乳液

泡沫乳液是油，水和气体的混合物。气泡被油和水制成的连续相包围。可以使用单一的表面活性剂或稳定剂混合物来稳定众多界面。这些系统用于制造多种材料，从采油到生奶油，可以在许多产品和工艺中找到。在本文中，介绍了遇到的不同类型的泡沫乳液及其稳定的具体困难。具有水连续相的发泡乳液是最常研究的，并给出了其稳定性和机械性能的更详细描述。
