Nabulsi soap

Nabulsi soap is a type of castile soap produced only in Nablus in the West Bank, Palestine. Its chief ingredients are virgin olive oil, water, and an alkaline sodium compound. The finished product is ivory-colored and has almost no scent. Traditionally made by women for household use, it had become a significant industry for Nablus by the 14th century. In 1907 the city's 30 Nabulsi soap factories were supplying half the soap in Palestine. The industry declined during the mid-20th century following destruction caused by the 1927 Jericho earthquake and later disruption from the Israeli military occupation. As of 2008, only two soap factories survive in Nablus.
