Abstract
The lipopeptides according to the invention are amphiphatic and consist of a hydrophobic chain containing from about 8 to 24 carbon atoms and of a peptide chain which is hydrophilic or has been rendered hydrophilic. They are applied, in particular, to emulsions of immiscible media and to the preparation of lyotropic liquid crystals.
