Molybdenum

Molybdenum (CAS 7439-98-7, EC 231-107-2, formula Mo) is a refractory transition metal supplied under trade designations including TsM1, MChVL, and catalogue reference MO008710. It carries no assigned E-code. It is classified within the Salts & Minerals category.

In catalysis, molybdenum acts as an active phase component in hydrodesulfurisation and hydroprocessing catalysts, where its d-orbital structure facilitates sulfur bond cleavage in petroleum fractions. In personal care formulations, it functions as an antimicrobial and skin-conditioning agent by interfering with microbial enzyme activity at low concentrations.

Molybdenum is available in wire and powder form, with powder particle size and purity grades selected according to end-use requirements in mining, pharmaceutical, and cosmetic applications. Procurement should confirm REACH registration status and supplier Safety Data Sheet compliance before import into the EU. Standard packaging formats vary by grade and order volume.
