With factories in Luchana, Axpe and Mataporquera and a share capital of 898 million pesetas, the presidency was given to Pedro Careaga (president of Banco Vizcaya) and the vice-presidency to Charles Benson Branco (representing the multinational Dow Chemical). In 1963, Dow Unquinesa's profits fell drastically to 1.6 million pesetas. In 1964, Dow Chemical and CEPSA built a petrochemicals plant in Tarragona. Four years later, Dow-Unquinesa was liquidated and taken over by Dow Chemical's Spanish subsidiary, then Dow Chemical Ibérica.
