Jan 05, 2021 Conclusion. Here we showed for the first time that the stability of W/W emulsions can be quantitatively characterized using analytical centrifugation. Three phenomena can be distinguished: coalescence of dispersed droplets, sedimentation (or creaming) of dispersed droplets and coalescence of sedimented (creamed) droplets into a continuous phase.
