Aqueous ionic solution containing seawater and at least one compound that is originally immiscible with sea water

Aqueous ionic solution, in particular intended for nasal use, comprising at least:

• a solution based on seawater having an osmolarity lying, for an isotonic solution, between 250 mOsm/kg and 350 mOsm/kg or, for a hypertonic solution, an osmolarity above 350 mOsm/kg, in a proportion by mass lying between approximately 25% and 98% with respect to the total mass of said aqueous ionic solution,
• at least one cationic phospholipid of natural origin in a proportion by mass lying between approximately 0.01% and 5% with respect to the total mass of said aqueous ionic solution,
• at least one compound originally immiscible with said solution based on seawater in a proportion by mass lying between approximately 0.01% and 10% with respect to the total mass of said aqueous ionic solution.
