Synopsis The purpose of this work was to compare the evolution of three multiple emulsions (ME) by different controls. The series of water-in-oil-in-water (W/O/W) multiple emulsions were elaborated and controlled by both the usual analyses which permitted the classification of the multiple emulsions with respect to their thermal stability, and the rheological oscillatory and flow analyses which are polyvalent methods. Further, these allow the 'identity card' of the multiple emulsion to be drawn, its evolution to be followed, and moreover, its behaviour being foreseen by simulating ageing by shear. Three different behaviours are observed; a destructuration, a phase inversion and stability. Résumé L'objectif de ce travail est de comparer, à l'aide de différentes analyses, l'evolution de trois émulsions multiples H/L/H. Ces émulsions sont contrôlées par des analyses classiques qui permettent de classer les émulsions en fonction de leur stabilité thermique, et des analyses rhéologiques en dynamique et en écoulement qui permettent de dresser la 'carte d'identité' de l'émulsion multiple, de suivre son évolution et enfin de prévoir son comportement après simulation du vieillissement par le cisaillement. Trois comportements sont observés; une destructuration, une inversion de phase et une stabilité.
