Our first 40 Years

In 2023 Valsynthese is celebrating the 40th anniversary from its foundation.

40 years ago, the Société Suisse des Explosifs (SSE) founded in Gamsen (Switzerland) its fine chemical unit Valsynthese, a second successful pillar, in addition to the production and sale of civil explosives.


Over the last four decades Valsynthese has evolved into a premium provider of development and production services and now it is a leading specialist in handling hazardous chemical reactions.


In Gamsen, Valsynthese manufactures products used in pharma, agro, animal health, fragrance & flavor and material science industries.

In recent years, technologies, development of internal skills, talents and systems, as well as new production installations allowed Valsynthese  to effectively expand its know-how and consolidate its experience as well as its product portfolio.

Located in the centre of Europe surrounded by fascinating and unspoiled territory, Valsynthese is regarded as one of Europe's highly experienced chemical producers in the field of CDMO.


This first major milestone of 40 years has been reached!

We are ready to face the next 40 years with the same enthusiasm and commitment!

The fine chemicals unit at SSE has undergone a great development in recent years and has impressively confirmed that it is an important pillar in our Group. Today, fine chemicals make a significant contribution to the competitiveness of our Gamsen site. I am delighted to celebrate this important achievement!

Gilles de Preux, CEO SSE Group.

Entrepreneurship, innovation, passion, and teamwork characterize our employees at the Gamsen site. They can be justifiably proud to be part of Valsynthese success story.
