Sigma-Aldrich International Gmbh
Sigma-Aldrich International Gmbh is a Private limited company (Ltd.) registered in Switzerland under CHE105315977, and its current status with Zefix — Swiss Central Business Names Index is active. Its registered address on file is Buchs Sg, Switzerland. 1 shareholder is on record for Sigma-Aldrich International Gmbh, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Zefix — Swiss Central Business Names Index and was last updated on 29 September 2026.

Shareholders of Sigma-Aldrich International Gmbh
One shareholder is currently on record for Sigma-Aldrich International Gmbh, reflecting the Aktienbuch (share register) maintained under Article 686 of the Swiss Code of Obligations rather than a public filing. The largest of these is Sigma-Aldrich Holding Ag, holding 100% — a majority holding. Because the shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Directors and officers of Sigma-Aldrich International Gmbh

Florence Jolidon serves as Geschäftsführerin; Dennis Tschudin serves as Vorsitzender Der Geschäftsführung; Michael Muhlhofer and Petra Dorothea Jordan both serve as Mit Kollektivprokura Zu Zweien. Management authority at Sigma-Aldrich International Gmbh sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control. The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.

Data availability
Those 15 subsidiaries span Switzerland, Singapore, Poland, Hungary, Hong Kong, Luxembourg, and 8 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Nine of the 15 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
