Abstract

A little emulsion: the WOW factor Small water droplets within larger oil droplets that are themselves distributed in an aqueous phase are a type of double emulsion. Though they offer certain advantages over water-in-oil emulsions, water-in-oil-in-water (WOW) emulsions are difficult to prepare and tend to be unstable, requiring complex techniques or surfactant mixtures. A multi-department team from the University of California, Los Angeles, has now developed a method of preparing double emulsions that are stable for months using amphiphilic diblock copolypeptides in which the control of H-bond presentation in polypeptide segments acts as a stabilizing factor. The method can even generate robust double nanoemulsions — not possible with established methodologies — that could be useful in cosmetics, food and drug delivery.
