The invention relates to novel materials based on biodegradable homopolyamino acids and which can be used for the vectorization of (an) active ingredient(s) (AI). The invention also relates to novel pharmaceutical, cosmetic, dietetic or phytosanitary compositions based on said homopolyamino acids. The aim of the invention is to produce a novel polymer raw material which can be used for the vectorization of AI and which meets all specifications in an optimum manner: biocompatibility, biodegradability, the ability to become easily associated with a large number of active ingredients or to solubilize them and to release said ingredients in vivo. According to the present invention, which primarily relates to linear homopolyamino acids having aspartic or glutamic units and whose extremities include hydrophobic groups having 8-30 carbon atoms. Said homopolymers are amphiphilic and anionic and can easily be transformed at low cost into particles for the vectorization of active ingredients. Said particles can form stable aqueous colloidal suspensions.
