Environmentalists call these 12 chemicals the Dirty Dozen. Here's why.

Warning: Abbreviations ahead!

True
Seventh Generation

You may have heard of the Dirty Dozen — 12 chemicals that activists have identified as potentially harmful that we regularly come in contact with in our home, health, and beauty products.

Over the past decade, a lot of science and research has gone into figuring out the long- and short-term health effects of products we use in our homes and on our bodies. The jury is still out on most of them, but some of the findings are worth a closer look.

In 2010, Canada's David Suzuki Foundation did a study on the 12 chemicals and compounds they felt consumers should try to avoid. Since the study was published, some governments have banned some of the chemicals and some companies are reformulating their products so they don't contain them.


Are the Dirty Dozen hanging out in your home somewhere? Here's why these ingredients are on the list:

1. BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene)

These two preservatives can be found in moisturizers and cream makeups. Image via iStock.

These two synthetic antioxidants are often used as preservatives in cosmetics (mostly lipsticks and moisturizers) and as food preservatives. They're also potentially allergenic, particularly on the skin.

The International Agency for Research on Cancer classifies BHA and BHT as possible human carcinogens, and the European Commission on Endocrine Disruptors lists BHA as a Category 1 priority substance, citing evidence that it interferes with hormone function in mice and rats.

Neither BHA nor BHT are restricted in the United States. California includes BHA on its list of chemicals that must be listed on product ingredient labels as potentially cancer-causing.

2. Coal tar dyes: p-phenylenediamine and colors listed as "CI" followed by a five-digit number

Coal tar dyes (chemical name p-phenylenediamine) are very popular in the cosmetic industry — particularly in hair dye — because they provide rich, long-lasting color. But, like a lot of petroleum-based products, some researchers and activists fear there may be health risks from exposure to them.

Research has linked coal tar dyes to tumors in laboratory mice, and other researchers may have found a connection between long-term use of hair dyes and non-Hodgkin lymphoma. The U.S. Food and Drug Administration (FDA) is unconvinced; it's waiting to see more research before making a firm decision on how to classify coal tar dyes.

The European Union (EU), by comparison, has taken a precautionary approach and classifies coal tar dyes as moderately toxic to humans.

Helpful hint: If you're looking at labels, you can tell if a coal tar dye is used in a product by looking for the the name p-phenylenediamine or the abbreviations FD&C or D&C followed by a five-digit color index number.

3. Diethanolamine (DEA), cocamide DEA, and lauramide DEA


Some shampoos get an extra kick from DEA. Image via iStock.

Consumers love creamy or sudsy personal care products. DEA helps with that. For personal care products, it's most common in moisturizers, sunscreens, and shampoos. As a cleaning product additive, it can be found in soaps and cleansers looking for an added bubbly kick.

Activists became concerned about DEA after some research found that DEA can cause skin and eye irritation, and some high doses have caused liver cancers in to laboratory animals. There are no restrictions on the use of DEA in the United States, but the EU does not allow its use in cosmetics, citing the risk of long-term exposure.

4. Dibutyl phthalate (DBP)

Some "no-chip" nail polishes may get their staying power from DBP. Image via iStock.

Dibutyl phthalate has lots of uses. It can keep nail polishes from chipping, help keep PVC flexible, and be a solvent for dyes or fragrances. The reason activists put it on the list of ingredients to keep an eye on is because in a laboratory study, researchers found it absorbs through the skin and can "enhance the capacity of other chemicals to cause mutations." Other research found it interfered with hormone function, maybe even for pregnant women. There's still a lot of research to be done, so the U.S. hasn't put any restrictions on DBP; the EU, though, does not allow it in cosmetic products.

5. Formaldehyde-releasing preservatives

These are medical sutures stored in formaldehyde, but lots of beauty and personal care products use chemicals that may release formaldehyde over time. Image via iStock.

Formaldehyde has a lot of uses in personal care, cleaning products, and industrial construction. It is found as a preservative in cosmetics and an active ingredient in some toilet bowl cleaners. It can also be released from a wide range of industrial products including some permanent-press fabrics and vinyl and wood-laminate flooring.

The U.S. Environmental Protection Agency (EPA) limits the amount of formaldehyde in some construction materials because on its own, formaldehyde is a carcinogen and is toxic to humans if ingested.

When personal care products or cosmetics are said to contain formaldehyde, what they usually contain are actually formaldehyde-releasers. It's unclear whether they are harmful; the FDA doesn't restrict the use of them in cosmetics or personal care products, preferring to require disclosure on ingredient labels instead. The EU has strongly restricted the use of formaldehyde in industrial and consumer products since 2014, citing its carcinogenic risk.

6. Parabens

Parabens help some cosmetics stay pretty longer. They may also be dangerous. Image via iStock.

If you drink fruit juices or use cosmetics or fragrance products, you likely have encountered parabens, an extremely popular preservative.

Some activists are concerned by parabens, citing research that it potentially has adverse health risks when it's absorbed through the skin. Some studies have shown that parabens can mimic the effects of estrogen, the female sex hormone which could lead to a possible increase to breast cancer risk or potentially interfere with male reproductive function. Despite activists' concerns, more definitive research is needed.

7. Parfum (aka fragrance)

Lots of products use the catch-all terms parfum and fragrance for the proprietary mix of chemicals that make up their signature scents. Image via iStock.

Since there are no regulations requiring companies to disclose the ingredient lists of their signature scents, many of them simply say parfum or fragrance on the label. This can be misleading because the smells that make up a fragrance can come from any number of essential oils or chemical compounds.

For people with chemical sensitivities, these unlisted ingredients can trigger allergic reactions, migraines, or cause asthma. Environment Canada has also found that some synthetic musks used in fragrances can build up in the fatty tissue of fish and other water-bound organisms. Other fragrance additives, like DEP (see #4 above) help scents stay in the air longer, but have been shown in laboratory environments to potentially interrupt hormone functions.

Unfortunately, it is hard to know whether a specific fragrance or parfum contains potentially unsafe ingredients. If companies say their product fragrance is a trade secret, they aren't required to list what's in it on the ingredient label.

8. Polyethylene glycol (PEG)

PEG compounds can be found in some cosmetic cream bases — and laxatives. Image via iStock.

Polyethylene glycols are petroleum compounds most often found helping makeup and face creams deliver moisture. If perfectly pure, they are considered generally safe, though they're not recommended for use on broken skin. In rare cases, polyethylene glycol compounds can become contaminated with ethylene oxide, and that's when activists get concerned. Ethylene oxide is a known carcinogen that has also been shown in some research environments to cause developmental problems. All of this considered, the Environmental Working Group rates the overall hazard of using polyethylene glycols as "low."

9. Petrolatum (aka petroleum jelly or Vaseline)

Some glossy lipsticks get their shine from petrolatum. Image via iStock.

Tyra Banks swears by mineral oil jelly as her holy grail makeup product. It's an excellent moisture barrier to keep skin hydrated and is often added to skin care and hair care products.

But, because it is petroleum-based, there's a risk it could be contaminated with polycyclic aromatic hydrocarbons. Research has shown a link between long-term exposure to these petroleum byproducts and cancer. Based on that evidence, the EU classifies petrolatum as a carcinogen and only allows its use "if the full refining history is known and it can be shown that the substance from which it is produced is not a carcinogen." There are no such restrictions in the United States at the moment.

10. Siloxanes

Siloxanes are a group of chemical compounds based on silicone, a popular additive in many cosmetics and personal care products. Image via iStock.

If you like a clean windshield, dry underarms, or a smooth makeup base, you've probably used products containing siloxane. Two siloxanes in particular, cyclotetrasiloxane (D4) and cylcopentasiloxane (D5), have been studied by researchers in Canada and the EU extensively.

Environment Canada concluded that both D4 and D5 may build up in fish or other aquatic organisms but did not pose a threat to human health. The European study reached a similar conclusion, rating the chemicals as "high concern" but of no risk to human health.

11. Sodium laureth sulfate

Sodium laureth sulfate helps some shampoos stay foamier for longer. Image via iStock.

If you like lots of bubbles when you wash dishes or use shampoo, you may have sodium laureth sulfate to thank. It's a common foaming agent used in dish soaps, cleansers, and foamy beauty products. But, like polyethylene glycol (#8 on this list), sodium laureth sulfate can — on rare occasions — become contaminated with the known carcinogen ethylene oxide. Fortunately that's very unlikely to happen, so the Environmental Working Group rates the overall hazard of sodium laureth sulfate as "low."

12. Triclosan

Triclosan is an antibacterial chemical sometimes found in alcohol-based hand sanitizers. Image via iStock.

Triclosan is a very effective anti-bacterial chemical found in lots of common consumer products, including toothpaste, hand sanitizers, laundry detergent, and facial tissues, among others.

As we've written before, research has shown that triclosan sticks around in the environment long after we've finished using it, killing helpful algaes and even accumulating in the bodies of other organisms.

Triclosan was banned in personal care products ibanned in personal care products in the EU earlier this year. The EPA currently has it under review, and the FDA is reserving judgment until further research is done.

For a lot of these products, the research into their possible health impacts is still very new. Much is still to be done, and the definitive answers for what's safe and what's not may not be known for years — maybe even decades.

Until there is a scientific consensus, the smartest thing you can do for your health is what you're probably already doing: reading product labels, following warnings, and learning what companies are required to say (and sometimes don't say).

Making new friends as an adult is challenging. While people crave meaningful IRL connections, it can be hard to know where to find them. But thanks to one Facebook Group, meeting your new best friends is easier than ever.

Founded in 2018, NYC Brunch Squad brings together hundreds of people who come as strangers and leave as friends through its in-person events.

“Witnessing the transformative impact our community has on the lives of our members is truly remarkable. We provide the essential support and connections needed to thrive amid the city's chaos,” shares Liza Rubin, the group’s founder.

Despite its name, the group doesn’t just do brunch. They also have book clubs, seasonal parties, and picnics, among other activities.

NYC Brunch Squad curates up to 10 monthly events tailored to the specific interests of its members. Liza handles all the details, taking into account different budgets and event sizes – all people have to do is show up.

“We have members who met at our events and became friends and went on to embark on international journeys to celebrate birthdays together. We have had members get married with bridesmaids by their sides who were women they first connected with at our events. We’ve had members decide to live together and become roommates,” Liza says.

Members also bond over their passion for giving back to their community. The group has hosted many impact-driven events, including a “Picnic with Purpose” to create self-care packages for homeless shelters and recently participated in the #SquadSpreadsJoy challenge. Each day, the 100 members participating receive random acts of kindness to complete. They can also share their stories on the group page to earn extra points. The member with the most points at the end wins a free seat at the group's Friendsgiving event.

Terrified, emaciated dog comes to life as volunteer sits with him for human connection

He tries making himself so small in the kennel until he realizes he's safe.

Terrified dog transforms after human sits with him.

There's something about dogs that makes people just want to cuddle them. They have some of the sweetest faces with big curious eyes that make them almost look cartoonish at times. But not all dogs get humans that want to snuggle up with them on cold nights; some dogs are neglected or abandoned. That's where animal shelters come in, and they work diligently to take care of any medical needs and find these animals loving homes.

Volunteers are essential to animal shelters running effectively to fill in the gaps employees may not have time for. Rocky Kanaka has been volunteering to sit with dogs to provide comfort. Recently he uploaded a video of an extremely emaciated Vizsla mix that was doing his best to make himself as small as possible in the corner of the kennel.

Kanaka immediately wanted to help him adjust so he would feel comfortable enough to eat and eventually get adopted. The dog appeared scared of his new location and had actually rubbed his nose raw from anxiety, but everything changed when Kanaka came along.

Woman's felony charge for 'abuse of a corpse' sheds light on the realities of miscarriage

Let's start with the unspoken and uncomfortable fact that miscarriages at home usually happen in a toilet.

Woman's felony charge after miscarriage highlights need for education.

Content Warning: This story discusses pregnancy loss details that may be uncomfortable for some readers.

Losing a pregnancy is not something anyone can prepare for. There's no course you can take to tell you what to expect, how you'll feel or what to do after the miscarriage occurs. It's not something that's widely talked about, even in conversations about miscarriage.

About 1 in 4 pregnancies end in miscarriage in the first trimester and 1 in 5 in the second, according to the March of Dimes. Many women who reveal they've lost a pregnancy talk about how difficult it was emotionally, but they rarely talk about the lack of information from medical professionals or the details of the process of miscarrying. It makes sense because it's hard enough to discuss pregnancy loss, and to go into detail may be much worse on their mental health.

There also may be a level of shame attached to the process, partly because the topic of miscarriage is still taboo but also because many at-home miscarriages happen in the toilet. It's an uncomfortable truth that haunts people who have experienced the process. But the truth of the matter is, hospitals don't usually admit you for a miscarriage; they send you home with little to no instructions on what to do after it happens. So to people who have experienced the pain of a miscarriage at home, it makes sense that a woman in Ohio, currently on trial for "abuse of a corpse" would have no idea what to do after miscarrying.

Woman's wild story of surviving 14,500 ft skydive fall because of fire ants is a must read

It's usually a bad thing to land in a mound of fire ants at 80 mph. But not if you're Joan Murray.

Picture of a fire ant. Eek.

You have a 50% chance of surviving a fall of 48 feet, roughly equaling a 4-story building. The mortality rate rushes all the way up to 90% when you fall 84 feet, the distance of a 7-story building.

So if you’re falling from a whopping 14,500 feet, just over two-and-a-half miles, you can safely bet that you’re most definitely not getting out alive.

But one woman did. And that’s not even the wildest part of her story.

People kept telling me to watch 'Bluey.' I still was not prepared.

Some adults say it's healing their inner child, but there's something in the popular Australian kids' show for everyone.

"Bluey" is popular with all ages, despite being aimed at kids.

I have a confession to make. I'm 48 years old, my youngest child is in high school and I can't stop watching "Bluey."

For the uninitiated, "Bluey" is a kids' cartoon from Australia aimed at 5 to 7-year-olds. It's been nearly a decade since my household has seen that demographic, so when people kept telling me I should watch "Bluey," my reaction was basically, "Yeah, I've already done my kiddie show time, thankyouverymuch."

Then my almost-15-year-old started watching it just to see what the fuss was about. And as I started tuning in, I saw why people love it so much. I figured it was going to be a wholesome show with some good lessons for kids, and it is.

But it's also laugh-out-loud hilarious.
