Tetrahedron is a privately held company created in July 2003 by Jean-Claude YADAN, Irene ERDELMEIER and Marc MOUTET.

Mission

The goal of Tetrahedron is to help maintain or restore a healthy life by designing and developing new active ingredients for cosmeceutical, nutritional, biomedical and therapeutical applications.

These ingredients may be:

• Natural compounds, such as L-ergothioneine, for which Tetrahedron develops new and sustainable synthesis processes allowing an industrial production of these compounds. In this regard, Tetrahedron proposes L-ergothioneine in bulk quantities, as ERGONEINE® for Nutrition and as BIONEINE® for Cosmetics.
• Or original molecules derived from natural compounds, such as NutraSelen®, a precursor of L-selenomethionine, therefore providing proprietary compounds.

Expertise

The Management Team has a shared experience of over 20 years in designing and managing R&D projects in Cosmetics, Diagnostics, Nutrition and Therapeutics, including in particular the Research and Development of new active compounds and the patent filing.

Its expertise lies at the Chemistry-Biology interface, in Free Radical Biology, Enzymology, Sulphur and Selenium Chemistry, as well as in process development in the context of sustainable chemistry.
