Endocrine disruptors and asthma-associated chemicals in consumer products

Look down a shopping aisle and you will find that labels on household and personal care products list a litany of chemical ingredients. Consumers who prefer less industrial alternatives can choose “green” or “natural” products that claim to be chemical free, but what actually goes into them is often unclear.
A 2012 study published in Environmental Health Perspectives, “Endocrine Disruptors and Asthma-Associated Chemicals in Consumer Products,” analyzed the composition of 42 household cleaning and personal care products and 43 “chemical free” products.
Results of the study include:
- The products analyzed contained 55 different chemical compounds: 50 were found in the 42 conventional samples representing 170 product types, while 41 were detected in 43 “chemical free” samples representing 39 product types.
- Eleven chemical compounds were detected at concentrations greater than 1%, and 26 were detected at concentrations above 0.1%.
- Parabens, a class of chemicals that has been associated with reproductive-tract issues, were detected in seven of the “chemical free” products, including three sunscreens that did not list parabens on the label.
- Vinyl products such as shower curtains were found to contain more than 10% by weight of the compound DEHP, which when present in dust has been associated with asthma and wheezing in children.
- The risk of exposure to chemical compounds increases as products, both conventional and “chemical free,” are used in combination. “If a consumer used the alternative surface cleaner, tub and tile cleaner, laundry detergent, bar soap, shampoo and conditioner, facial cleanser and lotion, and toothpaste [he or she] would potentially be exposed to at least 19 compounds: 2 parabens, 3 phthalates, MEA, DEA, 5 alkylphenols, and 7 fragrances.”
The authors of the study found that “multiple chemicals of concern [exist] in composites of high market-share products,” and they call for “disclosure of product ingredients [that] would enable researchers to identify exposures for study and risk evaluation and allow consumers to make decisions consistent with their personal values.”
