Musk Xylene

Musk 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.

Use of musk xylene has declined sharply since the mid-1980s due to safety and environmental concerns. Its explosive and carcinogenic hazards are recognized to be borderline, and musk xylene is a useful example of the lowest level of such risks which need to be taken into account. However, it is a very persistent and very bioaccumulative polluant in the aquatic environment (vPvB substance), and is the first substance to be proposed as a "substance of very high concern" (SVHC) for these reasons alone under the European Union REACH Regulation.
