Abstract
The creation of a limpid, stable micro-emulsion from liquid lipophilic materials of vegetable origin, specifically, essential oils, using an ecologically optimized solubilizing agent consisting of a mixture of one ethoxylated vegetable oil and at least one supplemental surfactant comprising an anionic surfactant derived from another vegetable oil and/or a non-ionic co-surfactant. The micro-emulsion retains the original active properties of the essential oils in addition to the specific individual properties of the solubilizing agent or the mixture thereof with the lipophilic vegetable materials. Applications: all the applications of essential oils and those conferred by the addition of the specific surfactants.
