This is one of the longest running chemistry webpages on the internet. Each month since January 1996 a new molecule has been added to the list on this page. The links will take you to a page at one of the Web sites at a University Chemistry Department or commercial site in the UK, the US, or anywhere in the world, where useful (and hopefully entertaining! ), information can be found about a particularly interesting molecule. Each month's new molecule will be announced on Twitter [@Molecule M] and via an RSS newsfeed [ If you wish to contribute a page, just email me the URL and I'll add you to the list at the next opportunity. (There's generally a 2-3 month waiting list, so this gives you plenty of time to write and polish your page). Pronounced THAL-ates, these chemicals, which are linked to endocrine disruption, developmental and reproductive toxicity, and cancer, have been banned from cosmetics in the European Union, but still remain prevalent in U. Phthalates share a similar chemical structure and are widely used in consumer products.2) DEP is widely used in scented products to help the scent linger, although it is rarely found on labels because it is a constituent of the ubiquitous ingredient “fragrance.” A third phthalate, Di-2-ethylhexylphthalate (DEHP) is found in eyelash glue, and is widely used in other consumer products. FOUND IN: Color cosmetics, fragranced lotions, body washes and hair care products, nail polish and treatment WHAT TO LOOK FOR ON THE LABEL: phthalate, DEP, DBP, DEHP and fragrance WHAT ARE PHTHALATES? Not Too Pretty: Phthalates, Beauty Products and the FDA. A significant loophole in federal law allows phthalates (and other chemicals) to be added to fragrances without disclosure to consumers. In field research, the Campaign for Safe Cosmetics only found phthalates listed as an ingredient in nail polish, Phthalates are commonly found in human urine samples. Not Just a Pretty Face: The Ugly Side of the Beauty Industry. An analysis of the 1999-2000 data from the CDC’s National Biomonitoring Program found metabolites of DEP in all 2,540 samples and metabolites of DBP in 99% of samples. The researchers speculate that the high prevalence of DEP is the result of the chemicals’ use in cosmetics and other fragranced products. Levels of DEP metabolites were higher among non-Hispanic blacks, perhaps due to frequent and prolonged use of products marketed specifically to girls and women of color.

Studies on its antibacterial qualities and mechanisms are growing. Research suggests that it is similar in its mechanism to triclosan and is effective in fighting infections by targeting the growth of bacteria such as Staphylococcus aureus. Additional research seeks to understand its potential for causing antibacterial resistance and its effects on organismal and environmental health. In December 2013, the Food and Drug Administration required all companies to prove within the next year, that triclocarban is not harmful to consumers. In recent years, companies like Johnson & Johnson, Procter & Gamble, Colgate-Palmolive, and Avon have begun phasing out chemical use due to health concerns. Triclocarban, 3-(4-chlorophenyl)-1-(3,4-dichlorophenyl)urea, is a white powder that is insoluble in water. While triclocarban has two chlorinated phenyl rings, it is structurally similar to carbanilide compounds often found in pesticides (such as diuron) and some drugs. Once praised for its benefits in preventing breast cancer recurrence, the lucrative pharmaceutical drug tamoxifen is now implicated in causing dangerous side-effects, including other types of cancers. In the early 1970’s, a shameful chapter closed on the widespread use of a known carcinogenic and endocrine-disrupting drug called DES (diethylstilboestrol), the first synthetic, non-steroidal estrogen drug. Against the advice of its creator, Sir Charles Dodd, between four and six million American and European women and 10,000 Australian women innocently used DES for the prevention of miscarriage and pregnancy complications. In addition, DES became a popular though unproven drug for a variety of other conditions. It was used for the suppression of lactation, the treatment of acne, the treatment of certain types of breast and prostatic cancer, and as an inhibitor of growth in young girls, an estrogen replacement in menopause and a “morning after” pill. It would take 30 years to accept what laboratory tests had indicated as early as 1938 — that DES was a highly dangerous and harmful drug. It was reported that, 20 years after taking DES, mothers had a 40 to 50 per cent greater risk of breast cancer than non-exposed mothers.
