A series of experiments were conducted across a transitional phase inversion path, which often leads to formation of nanoemulsions, with the speed of incorporation of the second phase (water) into the first phase (oil) being altered. The optimum condition could only be achieved if the optimum composition was maintained for a critical time. A slow addition (addition time > 60 s) of water to the oil allows the transitional phase inversion to become operative, leading to formation of sub-micrometer droplets. A very fast addition of the water phase ( Note de contenu : Transitional Phase ISSN : 0888-5885 En ligne : http://pubs.acs.org/doi/abs/10.1021/ie901577f [article] Dynamics of transitional phase inversion emulsification : effect of addition time on the type of inversion and drop size [texte imprimé] / Fatemeh Jahanzad, Auteur ; Dimitris Josephides, Auteur ; Ali Mansourian, Auteur . - 2010 . - pp.7631–7637.
