DescriptionMusk xylene, or 5-tert-butyl-2,4,6-trinitro-m-xylene, was the most widely used of the 'nitro-musks', a type of synthetic musk fragrance, which mimic natural musk. It has been used as a perfume fixative in a wide variety of consumer products, and is still used in some cosmetics and fragrances. Musk xylene was included in 2008 in the European Chemicals Agency (ECHA) list of Substances of Very High Concern (SVHC) due to its being a vPvB substance (very persistent and very bioaccumulative). Substances in the list of SVHCs are those for which ECHA is considering imposing a requirement for authorization for some or all uses.
