The Swedish National Food Administration in Uppsala and the Karolinska Institute in Stockholm have been looking at the potential toxicity of musks following their discovery in human milk, when mothers are breastfeeding.1

Scientists set out to correlate the use of perfumed products during pregnancy monitoring the amount of seven synthetic musks in the breast milk of Swedish women. The milk samples underwent liquid–liquid extraction and the lipids were removed by gel permeation chromatography. Final extractions were analysed by GC–MS with electron ionization employing two deuterium-labelled synthetic musks as internal standards.

There was a positive correlation between the levels of the polycyclic musks, galaxolide and tonalide but none between the latter two and the nitro musk xylene.
