'''European Union merger law:''' is a part of the law of the European Union which regulates whether firms can merge with one another and under what conditions. It is part of competition law and is designed to ensure that firms do not acquire such a degree of market power on the free market so as to harm the interests of consumers, the economy and society as a whole. 
Concentration: Under European Competition law, a concentration exists when a "change of control on a lasting basis results from (a) the merger of two or more previously independent undertakings. (b) The acquisition, direct or indirect control of the whole or parts of one or more other undertakings." Art. 3(1), Regulation 139/2004, the European Community Merger Regulation. This avoids the establishment of market structures which may create or strengthen a dominant position and not need to control directly possible abuses of dominant positions.

'''European Commission on Sanex Uniliver acquisition:''' The proposed acquisition was notified to the Commission on 21 April 2010, on 31 May 2010 the Commission opened and in-depth investigation over fears it would harm consumers by giving the merged too much power in a number of product markets. The European Commission cleared under the European Union Merger Regulation (EMRC) the planned acquisition by Unilever of Sara Lee Corp of the US, subject to conditions. The Commission's in-depth investigation, confirmed competition concerns in a number of deodorants markets. To remedy these concerns, the merging parties offered to divest Sara Lee's Sanex brand and related business in Europe. In light of these commitments, the Commission concluded that the proposed transaction would not significantly impede effective competition in the European Economic Area (EEA) or any substantial part of it. The Commission's decision was conditional upon full compliance with the commitments. The Commission's in-depth investigation has shown that the merger would give Unilever a very strong leadership position in a number of deodorants markets by combining the parties' brands, most notably Sanex with Dove and with Rexona which presently compete against each other. The Commission found that the merger, as initially notified, would raise competition concerns in Belgium, The Netherlands, Denmark, the United Kingdom, Ireland, Spain and Portugal where it would remove an important competitive force and would likely  lead to price increases.
