We report the formulation of a concentrated double oil-in-water-in-oil (O/W/O) emulsion for fragrance encapsulation.As their water-in-oil-in-water homologous, these O/W/O emulsions, seldom described in literature, also require the use of two antagonist surfactants: a hydrophilic one (HS) to stabilize the fragrance-inwater droplets and a lipophilic one (LS) to stabilize the aqueous globules dispersed in oil, containing themselves the direct emulsion. An important issue in cosmetics is the necessity to adapt the formulation to each fragrance, so that a major progress would be the successful elaboration of an O/W/O emulsion insensitive to fragrance changes. In order to approach such a composition, two model fragrances composed of 10 and 13 molecules representative of the most used molecules in this domain were specially assembled for the study. The aim was to identify possible hydrophilic and lipophilic stabilizers leading to a double O/W/O emulsionsand determine compositions able to encapsulate both fragrances. The double emulsion was prepared by a twostepprocess, allowing varying the double emulsion composition i.e the amount of both surfactants as well asthe quantity of droplets inside the globules. By plotting “feasibility diagrams” we can propose a best compositionshared by the two fragrances. Such a double emulsion is composed of 20 wt% of fragrance dropletswith respect to the globule volume, 75 wt% of globules with respect to the total emulsion, 7.5 wt% of HS withrespect to the intermediate aqueous phase and 10 wt% of LS with respect to external oil phase. The robustnessof this optimized composition against molecule changes was tested using a third fragrance. Then the encapsulatedefficiency was measured showing the high encapsulation rate (close to 99 %) of the selected system.< Réduire
