Why it’s a concern
Nitromusks are persistent, bioaccumulative organic pollutants. Musk ketone has been detected in human breast milk, adipose tissue, and fish. The EU restricts its use in leave-on products to 1.4% and has reviewed it as a potential endocrine disruptor. Its degradation products include aromatic amines of toxicological concern.
