Abstract

The present invention refers to a carrier system for weakly water soluble substances comprising (i) a lipid compound, (ii) a cosolvent and (iii) water, with said system being a liquid constituted of a lyotropic phase in thermodynamic equilibrium, in the form of phase L3 (sponge phase), obtained from stoichiometrically defined proportions. The invention also contemplates a process for obtaining the said carrier system for weakly water soluble substances, as well as its use as a carrier medium for weakly water soluble substances, such as pharmaceuticals, pesticides, herbicides, proteins, amino-acids, vitamins, antibiotics and similar substances for the preparation of compositions or for the coating of nanoparticles.
