24 Mar 2014 --- BASF said it is striving to limit the supply restrictions to the “smallest extent possible”, following its announcement last week that it had been forced to declare Force Majeure on its citral plant in Ludwigshafen, Germany. The company had to make the declaration for citral-based aroma chemicals as well as Vitamin A and Vitamin E products for human and animal nutrition, following a fire which broke out on March 12 this year.
