A link to a Harvard study in "Genital size on a downward arc as intelligence is more treasured," inspired me to write this post. See: Harvard Gazette: Chemical exposure tied to sperm count I could write an entire thesis on this subject, but to get a gist of it: A major loophole in FDA's federal law lets manufacturers of products like shampoo, lotion, and body wash include nearly any ingredient in their products under the name "fragrance" without actually listing the chemical. Companies that manufacture personal care products are required by law to list the ingredients they use, but fragrances and trade-secret formulas are exempt. An analysis of the chemical contents of products reveals that the innocuous-looking fragrance often contains chemicals linked to negative health effects. Phthalates, used to make fragrances last longer, are associated damage to the male reproductive system, and artificial musks accumulate in our bodies and can be found in breast milk. Some artificial musks are even linked to cancer. And if you've got asthma, watch out-- fragrance formulas are considered to be among the top 5 known allergens, and can trigger asthma attacks. The same kinds of chemicals are often used for fragrances in cleaning products, scented candles, and air fresheners. To avoid those unpleasant side effects, choose fragrance-free products, but beware labels that say "unscented." It may only mean that the manufacturer has added yet another fragrance to mask the original odor. (source: Enviroblog: Ask EWG: What is "fragrance"?) I highlighted the part I thought LPSG would be interested in. If you live in an EU country you've got it a little better with the European Commission, but not by much. So - be careful when you look at the ingredients on certain items, because what you're often not seeing the entire picture.
