This soap, made with a base of black olive oil soap, for which Marius Fabre is a specialist manufacturer, is an innovative product because it is composed entirely of plant-based ingredients. This sets it apart from all so-called "mechanical" soaps, which are always based on petroleum-derived surfactants and solvents. This soap, to which crushed olive pits have been added, does not damage the hands but cleanses them thoroughly. As an added bonus, it will leave your hands feeling incredibly soft. Biodegradable, it also helps to protect our environment.
