  • Patent number: 8158134
    Abstract: The invention relates to compositions in the form of microemulsion preconcentrates that contain (a) a mixture that consists of a medium-chain triglyceride and an omega-9 fatty acid and/or an omega-6 fatty acid; and (b) a surface-active component that contains a polyoxethylene tenside. When contacted with water or with an aqueous medium these microemulsion preconcentrates form microemulsions. The microemulsions of the O/W type have an average particle size below 150 nm, preferably below 100 nm. The inventive microemulsion preconcentrates and microemulsions are suitable for use as vehicles for substances, namely active agents, that are hardly soluble in water, but soluble in components (a) and/or (b). In the aqueous phase, said microemulsions may contain water-soluble substances.

  • Patent number: 7871642
    Abstract: A nanodispersion comprises (a) a membrane-forming molecule, (b) a coemulsifier and (c) a lipophilic component, in pharmaceutical end formulations, the nanodispersion being obtainable by (?) mixing the components (a), (b) and (c) until a homogeneous clear liquid is obtained, and (?) adding the liquid obtained in step (?) to the water phase of the pharmaceutical end formulations, where steps (?) and (?) may be carried out without high energy mixing or homogenization. The nanodispersions prepared according to this invention are suitable as transport vehicles for pharmaceutical active agents.
