According to a new study conducted by Environmental Defence along with Campaign for Safe Cosmetics, all the big perfume brands contain loads of chemicals that can trigger allergic reactions or disrupt hormones.

The group alleges the perfume brands of containing unlisted secret chemicals.

Some of the major brands pointed out by the study are Giorgio Armani Acqua Di Gio, Jennifer Lopez J. Lo Glow, Calvin Klein Eternity (for women), Britney Spears Curious, and Dolce & Gabbana Light Blue.

According to the study, the above top end perfume brands contained 14 chemicals some of which have been linked to estrogen disruption, sperm production disruption and even cancer.

The study also found out that the perfumes further contained an average of 10 "sensitizing" chemicals that can trigger allergic reactions, such as nausea, headaches, wheezing, and vomiting.

Two synthetic musks linked to toxicity to the endocrine system, galaxolide and tonalide were found in 16 perfumes. Further from a total of 17 perfumes tested 12 contained DEP. The dreary chemical is found in 97% of the Americans and is linked to abnormal development of reproductive organs in baby boys and sperm damage in adult men.

Environmental Defence's Rick Smith blames the regulatory loopholes for the sorry state. He says that, “All you have to do is put the word ‘fragrance' on your ingredient list and you can shovel dozens of chemicals into that one word".

In response to the allegations Darren Praznik, of the Canadian Cosmetic, Toiletry and Fragrance Association said the no ingredients in the perfumes are secret and insisted that the report was flawed.
