The present invention relates to be use on ethoxylated fatty acid esters as self-emulsifiable compounds particularly useful for the preparation of phytosanitary treatment products or as drugs for veterinary or human use. According to the invention, said fatty acid esters comprises a total number of ethylen oxyde molecules such that the value HLB (hydrophilic-lipophilic balance) of said compounds is comprised between about 4 and about 10, preferably between about 4 and about 9. Said ethoxylated fatty acid esters form in an original way self-emulsifiable components without requireing any other surfactant, and they are biodegradable and capable of dissolving active principles which are little or non water-soluble.
La présente invention a pour objet l'utilisation d'esters d'acides gras éthoxylés comme composants auto-émulsionnables notamment utiles pour la préparation de produits de traitement phytosanitaire ou de médicaments à usage vétérinaire ou humain. Selon l'invention, ces esters d'acides gras comportent un nombre total de molécules d'oxyde d'éthylène tel que la valeur HLB (balance hydrophile-lipophile) desdits composés soient comprises entre environ 4 et environ 10, de préférence entre environ 5 et environ 9. Ces esters d'acides gras éthoxylés constituent de façon originale des composants auto-émulsionnables sans l'aide d'aucun autre agent tensioactif, et sont biodégradables et capables de dissoudre des principes actifs peu ou pas solubles dans l'eau.
