Abstract
The invention relates to particles. These particles comprise, at least on the surface, a wall formed of plant proteins crosslinked particularly by means of interfacial crosslinking between the plant proteins and an acylating polyfunctional crosslinking agent comprising at least two acylating groups, covalent bonds being formed between the acylatable groups of the proteins and the acyl groups of the acylating polyfunctional crosslinking agent. These particles are used for the manufacture of a cosmetic, pharmaceutical, dermatological or food composition.
