Vitamin B6 is also known as the "" anti dermatitis vitamin "". One of the B vitamins. Genus pyridoxine derivatives, including pyridoxine, pyridoxal, pyridoxamine, and three compounds, which exist in food in a form that can interconvert. But vitamin B6 in plants is mostly pyridoxine, while it is mostly pyridoxal and pyridoxamine in humans and animals. Human intestinal bacteria can also synthesize pyridoxine, in humans pyridoxine can be converted into pyridoxal and pyridoxamine, while the latter two cannot be converted into pyridoxine. All three have the same physiological activity. Vitamin B6 is rapidly converted to pyridoxal phosphate in humans, and this compound plays an important role in amino acid metabolism as a coenzyme for decarboxylase, transaminase, kynureninase, deaminase, and desulfhydrase. It is also an essential coenzyme for carbohydrate and fat metabolism, activity of the central nervous system, and haemoglobin production.

Musk xylene is a synthetic musk fragrance which mimics 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 once the most widely used of the "nitro-musks", but its use 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 pollutant 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. Since no company has applied for authorisation, therefore it is banned in the EU.
