Perfume or cologne can be an important part of your morning regimen, especially in the summer, but some popular products contain several questionable chemicals, according to a new study.

Recent lab tests found 37 chemicals in a variety of popular fragrances that weren’t disclosed, according to a report from the Campaign for Safe Cosmetics and the Environmental Working Group.

The groups commissioned tests on perfumes and colognes including Chanel Coco, Victoria's Secret (Stock Quote: LTD) Dream Angels Wish, Abercrombie & Fitch (Stock Quote: ANF) Fierce, Shock AXE Body Spray (Stock Quote: UN) and Old Spice (Stock Quote: PG) After Hours Body Spray and found 14 chemicals on average that didn’t appear on product labels. The chemicals are often simply listed as “fragrance” on labels, according to the Campaign for Safe Cosmetics.

Some of these chemicals are known hormone disruptors and allergens, may be linked to lowered sperm count and many are derivatives of crude oil, according to the report. Still more have not been tested for safety at all.

The hormone disrupting elements in perfumes have been linked to breast and prostate cancer, infertility, problems with the development of a fetus, thyroid problems and obesity, according to the report.

Perfumes containing musk ketone were found to accumulate in fatty tissues and breast milk. And fragrances aren’t just absorbed through the skin. When sprayed onto the body, they are often inhaled as well.

The California Air Resources Board has gone as far as issuing Unilever a $1.3 million fine because each shot of its Axe Body Spray for Men releases contaminants into the air, the report said.
