Fragrance chemicals in shampoos and body wash may disrupt hormones

Fragrance chemicals found in everyday shampoos and body washes can disrupt your hormones, particularly those that control reproduction. Products containing phthalates and synthetic musks expose you to these endocrine-disrupting chemicals during normal use.
The word "fragrance" on a cosmetic label can hide a cocktail of hundreds of undisclosed chemicals. Research has increasingly focused on two classes of compounds commonly found under this label: phthalates and synthetic musks.
- Reduced sperm count and motility in men
- Early puberty onset in girls
- Altered hormone levels in pregnant women
Synthetic musks (such as galaxolide and tonalide) are fat-soluble and accumulate in the body over time. Research has detected them in human breast milk, blood, and umbilical cord blood.
A 2018 study in *Environmental Health Perspectives* tracked urine levels of phthalate metabolites in women who switched to fragrance-free cosmetics for just three days. Levels dropped by an average of 27–45%.
- Shampoos and conditioners
- Body washes and shower gels
- Perfumes and colognes
- Laundry detergents and fabric softeners
- Choose products labeled "fragrance-free" (not "unscented," which may still contain masking fragrances)
- Look for brands that fully disclose their fragrance ingredients
- Use the EWG Skin Deep database to check product safety ratings
What you can doAI-generated
- ✓Switch your shampoo and body wash to products labeled "fragrance-free" instead of "unscented." The study showed phthalate levels dropped 27 to 45 percent in just three days after making this swap.
- ✓Read the ingredient list and avoid anything that says "fragrance" or "parfum" as a catch-all ingredient. Those words hide hundreds of chemicals including phthalates and synthetic musks that mess with your hormones.
- ✓Ask your laundry detergent and fabric softener brands whether they disclose their fragrance ingredients. If they won't, switch to unscented versions since these products add up over time and synthetic musks accumulate in your body.
- ✓Use the EWG Skin Deep database before buying any new cosmetic to check whether it contains phthalates or synthetic musks under its fragrance label.
