Cross-linked plant protein particles, in particular microparticles or nanoparticles, preparation method and cosmetic, pharmaceutical

摘要

The invention concerns particles, characterised in that they comprise at least on their surface, a wall formed by cross-linked plant proteins, in particular resulting from interface cross-linking between plant proteins and an acylating polyfunctional cross-linking agent, comprising at least two acylating groups, producing covalent bonds between the protein functions capable of being acylated and the polyfunctional acylating cross-linking agent acyl radical groups. Said particles are used for making a cosmetic, pharmaceutical, dermatological or food composition.
