Mitsui Chemicals Accelerates Ultradent Acquisition and Shifts Oral Care Hub to U.S.
Mitsui Chemicals said it completed its acquisition of U.S. oral care company Ultradent Products on Aug. 14, 2026, earlier than the expected September timeline, after competition and foreign investment approvals were obtained. It plans to move its oral care global HQ function from Japan to a U.S. holding company and will review the deal’s impact on consolidated financial results.
