Abstract

The present invention provides a method for the production of amphiphile particles having incorporated therein at least one active agent. The method comprises forming a dispersion of particles comprising at least one amphiphilic structuring agent in a solution of at least one active agent, heating said dispersion to an elevated temperature, followed by cooling to around ambient temperature. The loading provided thereby is typically at least 130% of the loading provided by equilibration of the particles in a solution of active agent. The invention also provides corresponding amphiphile particles.
