For hundreds of years Nablus has been famous for it's high quality olive oil soaps, made from locally produced virgin olive oil. The Nabulsi family has been involved in soap making for over 200 years, and established the Majed al Nabulsi Company in 1920. and liquid soaps since 2005. 

Traditionally made by women for household use, soap-making had become a significant industry for Nablus by the 14th century. In 1907 the city's 30 soap factories were supplying half the soap in Palestine. The industry declined during the 20th century following destruction caused by the 1927 earthquake, competition by modern soaps and later disruption from the Israeli military occupation.
