Nabulsi soap

Nabulsi soap (Arabic: صابون نابلسي‎‎, ṣābūn Nābulsi) is a type of castile soap produced only in Nablus in the West Bank, Palestine. Its chief ingredients are virgin olive oil (the main agricultural product of the region), 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. The old Arafat soap factory has been turned into a Cultural Heritage Enrichment Center.

Nabulsi soap was traditionally made by women for household use, even before the appearance of small soap-making factories in the 10th century. Trade with Bedouins was indispensable for soap-making, both in Nablus and Hebron, since they alone could furnish the alkaline soda (qilw) required by the process. By the 14th century a significant soap-making industry had developed in Nablus and the soap, reputedly prized by Queen Elizabeth I of England, was exported throughout the Middle East and to Europe.

The 19th century saw a major expansion of soap manufacturing in Nablus, which became the center of soap production throughout the Fertile Crescent. By 1907, the city's 30 factories were producing nearly 5,000 tons of Nabulsi soap annually, over half of all soap production in Palestine.John Bowring wrote of Nabulsi soap in the 1830s that it is, "highly esteemed in the Levant," and Muhammad Kurd Ali, a Syrian historian, wrote in the 1930s that "Nablus soap is the best and most famous soap today for it has, it seems, a quality not found in others and the secret is that it is unadulterated and well produced."
