Marseille soap has always been glorified for its many virtues - natural, hypoallergenic, endlessly handy (for body / home) and environmentally friendly.  All La Corvette Marseille soaps are certified ECOCERT GREENLIFE, based on the COSMOS standard, and manufactured according to the charter of the Union of Marseille Soap Professionals.  And, of course, still made in cauldrons supervised by a soap master.
