MOLYBDENUM CHLORIDE.

Avoid CAS 11119-46-3 / SKIN CONDITIONING

Molybdenum Chloride is an acutely corrosive and toxic inorganic compound. It exhibits extreme reactivity with water and moisture, leading to the rapid formation of highly corrosive hydrochloric acid. This substance is unequivocally unsuitable and unsafe for any application in precision skincare formulations.

Science

Upon dermal contact, Molybdenum Chloride violently reacts with ambient skin moisture to produce potent hydrochloric acid. This chemical transformation directly instigates severe chemical burns, tissue damage, and intense irritation at the epidermal and deeper dermal layers.

Sensitization risk High

Molybdenum(V) chloride (MoCl5) is categorized as a highly corrosive and toxic substance, known to cause severe skin burns and irreparable eye damage. Its pronounced moisture sensitivity results in violent reactions with water, releasing toxic gases and forming hydrochloric acid. The substance is also suspected of causing cancer (H351). Regulatory bodies including CIR, SCCS, and FDA have not conducted safety assessments for its use in cosmetics, definitively indicating it is not considered safe for such applications.
