Hidden Chemicals in Hannah Montana, Britney Spears, J.Lo Scents Could Be Hazardous to Your Health

Britney Spears Curious

Forget secondhand smoke—the Environmental Working Group thinks we should be worried about "secondhand scents" from perfumes containing hidden chemicals. A report from the EWG claims that best-selling fragrances like Chanel Coco, Britney Spears Curious, and Old Spice After Hours Body Spray contain a number of unlisted chemicals, many of which are associated with hormone disruption and allergic reactions.

The EWG's analysis came up with the following results:

Fourteen secret chemicals not listed on labels due to a loophole in federal law that allows companies to claim fragrances as trade secrets. American Eagle Seventy Seven contained 24 hidden chemicals, the highest number of any product in the study.
Ten sensitizing chemicals associated with allergic reactions such as asthma, wheezing, headaches, and contact dermatitis. Giorgio Armani Acqua Di Gio contained 19 different sensitizing chemicals, more than any other product in the study.
Four hormone-disrupting chemicals linked to a range of health effects including sperm damage, thyroid disruption, and cancer. Halle by Halle Berry, Quicksilver and Jennifer Lopez J. Lo Glow each contained seven different chemicals with the potential to disrupt the hormone system.
A recent EWG study found synthetic musk chemicals Galaxolide and Tonalide in the umbilical cord blood of newborn infants. The musk chemicals were found in nearly every fragrance analyzed for this study. Twelve of the 17 products also contained diethyl phthalate (DEP), a chemical linked to sperm damage and behavioral problems that has been found in the bodies of nearly all Americans tested.

The idea that fragrances can cause allergic reactions is nothing new, but the prospect of dealing with problems like sperm damage and cancer may put off any potential Old Spice Body Spray fans. Not all fragrances are created equal, of course. Dolce & Gabbana Light Blue contains only 7 hidden chemicals, making it practically innocuous compared to American Eagle 77, which contains a whopping 24 hidden chemicals.

A recent report from the President's Cancer Panel shows that it's virtually impossible to avoid exposure to cancer-causing chemicals in our daily lives. But come on—we can all do without smelling like J. Lo.

UPDATE: The Personal Care Products Council (the largest trade association representing the cosmetics and personal care industries) responds in a statement:

"The assertions in the report that some fragrance ingredients could be hormone disruptors are based on incomplete assessments of available scientific data about potential hormone affects and do not take into account actual exposure in cosmetic products.  The studies relied upon in the allegations are not directly relevant to human exposure, and many of the laboratory tests that have been done were completed under conditions that are not directly applicable to the use of these ingredients in cosmetic products. In some substances the hormone effects measured are tens of thousands of times less than what would be expected to cause effects in humans.  The weight of evidence in hormone disruption science today does not support the conclusions presented in this report."
