Some fragrance ingredients are not perfuming agents themselves but enhance the performance of perfuming agents. For example, diethyl phthalate (prounced tha-late), or DEP, is widely used in cosmetic fragrances to make the scent linger. Phthalates are choice ingredients in cosmetics because they are cheap and versatile. However, the European Commission on Endocrine Disruption has listed DEP as a Category 1 priority substance, based on evidence that it interferes with hormone function. xi Phthalates have been linked to early puberty in girls, reduced sperm count in men, and reproductive defects in the developing male fetus (when the mother is exposed during pregnancy). xii Phthalate metabolites are also associated with obesity and insulin resistance in men. xiii As well, Health Canada notes evidence suggesting that exposure to phthalates may cause liver and kidney failure in young children when products containing phthalates are sucked or chewed for extended periods. xiv DEP is listed as a Priority and Toxic Pollutant under the U.S. Clean Water Act, based on evidence that it can be toxic to wildlife and the environment. xv

Laboratory analysis of top-selling colognes and perfumes identified an average of 14 chemicals per product not listed on the label, including multiple chemicals that can trigger allergic reactions or interfere with hormone function.
