Abstract
A synthetic particulate vector comprising a non-liquid hydrophilic nucleus and an outer layer at least partially consisting of amphiphilic compounds, which is combined with the nucleus by hydrophobic interactions and/or ionic bonds. A process for preparing a particulate vector by encapsulating an ionizable active principle, vectors obtained according to such a process, and pharmaceutical, cosmeticological and food compositions comprising such vectors are also disclosed.
