What Your Shampoo Bottle Isn’t Telling You

I’m not the most discerning shopper when it comes to buying cosmetics or household products. (Why are parabens bad for you, again?) So if I saw the chemical diethanolamine listed on the back of a shampoo bottle, or decamethylcyclopentasiloxane on a surface cleaner, it probably wouldn’t stop me from buying it. But chances are I’d never see those those names, anyway.

The main reason for this, a new study in yesterday’s Environmental Health Perspectives points out, is that the state of product labeling in the US is pretty poor. How poor? The study’s researchers—who analyzed samples from 213 different consumer products ranging from cat litter to shaving cream, sunscreen, dishwater detergent, mascara, and vinegar—detected some 55 toxic chemicals. Many of these, they report, weren’t listed on the labels of products tested.

“The study shows that we are exposed to a complex mixture of toxic chemicals simply by going through our normal routines,” Andy Igrejas, who heads the group Safer Chemicals, Healthy Families, said in a press release.

Labels are important, the study’s authors write, because they help scientists determine whether (and to what degree) consumer products are responsible for toxic chemicals entering our bodies. We already know about some chemicals detected in the study (which was led by the Silent Spring Institute and partly funded by the Centers for Disease Control and Prevention): Fragrances, BPA, phthalates, among others, are associated with a variety of health risks, most commonly asthma and endocrine disruption.

Improved research, in turn, would help consumers like me a ton. For example: With better labeling and due diligence on my part, I might have known that using a shampoo containing diethanolamine might irritate the nose, throat, and skin. Some animal studies have linked the chemical with increased blood pressure and impaired vision. I might also have known that decamethylcyclopentasiloxane (a.k.a. D5) is a compound widely used in cleaning, personal care, and baby products that’s also pretty toxic; studies have shown D5 to be potentially carcinogenic, and can harm the nervous system, fat tissue, liver, and immune system (PDF)—all things that would sway me to opt for a cleaner free of these chemicals.

But the solution isn’t just about better labeling, Igrejas says. “We need the federal government to sort through the chemicals on the market and ensure they are restricted where necessary.”

Until then, it’ll be up to consumers to decide what products are best avoided. As a start, we’ve already written about what to watch out for in sunscreen and household cleaners, researched the scary world of BPA, and sought the truth behind eco-labels.

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
