The invention concerns the preparation of a clear and stable microemulsion from liquid lipophile substances of plant origin in particular essential oils using an ecologically optimised solubilising agent consisting of a mixture of an ethoxylated vegetable oil with at least an additional surfactant comprising an anionic surfactant derived form another vegetable oil and/or a non-ionic surfactant. Said microemulsion enables to preserve the original active properties of the essential oils while adding particular specific properties derived from the solubilising agent or the mixture thereof with the vegetable lipophile substances. The invention is useful for all applications of essential oils and those provided by the addition of specific surfactants.
La réalisation d'une microémulsion limpide et stable à partir de matières lipophiles liquides d'origine végétale notamment d'huiles essentielles utilise un agent solubilisant écologiquement optimisé constitué d'un mélange entre une huile végétale éthoxylée et au moins un tensioactif supplémentaire comprenant un tensioactif anionique dérivé d'une autre huile végétale et/ou un co- tensionactif non ionique. Cette microémulsion permet de garder les propriétés actives d'origine des huiles essentielles en ajoutant des propriétés spécifiques propres provenant de l'agent solubilisant ou du mélange de celui- ci avec les matières lipophiles végétales. Applications: toutes les applications des huiles essentielles et celles conférées par l'ajout des tensioactifs spécifiques.
