Abstract
The invention relates to a lipid particle forming matrix, characterized by, that from a defined system of at least two lipid components chosen from classes of different polarity, in which at least one of the lipid components is bilayer forming, discrete lipid particles are formed spontaneously when interacting with aqueous systems. Preferably at least one of the lipid components is amphiphatic and polar and one is nonpolar. These discrete particles are formed spontaneously from the matrix without any chemical or physical treatment or initiation. The invention also relates to a process for producing the matrix and use thereof.
