Nitromusks known as musk ketone and polycyclic musks along with Galaxolide and Tonalide are most commonly found in many perfumes for women, lotions, colognes and body sprays and fragrance for men. They’re less commonly found in exfoliating products, acne treatments, facial moisturizer and other body care products.
The biggest issue with synthetic musks is the total lack of research surrounding them. Several studies suggest synthetic musks may disrupt hormone systems or trigger skin sensitization when exposed to UV light. Synthetic musks identified in fragrances have been found in the cord blood of newborn babies and in blood, breast milk and body fat. Other possible issues include developmental/reproductive toxicity, persistence and bioaccumulation, irritation (skin, eyes, or lungs) and organ system toxicity.
