Is “Non-Toxic” Nail Polish Really Non-Toxic? Maybe Not, Study Shows

Nail polishes have been linked to birth defects, thyroid problems, obesity, cancer, and allergic reactions. That’s why many people specifically shop for polishes labeled “non-toxic.” But as past research shows, even nail polishes marketed as non-toxic may contain chemicals that are harmful to your health. [1]

Study co-author Anna Young, a doctoral student at Harvard University, said: [2]

“It’s sort of like playing a game of chemical Whac-A-Mole, where 1 toxic chemical is removed and you end up chasing down the next potentially harmful chemical substituted in.”

It’s not just the nail polish industry that does this; it’s also commonplace in the pesticide and plastics industry.

Supposedly non-toxic nail polishes appeared on the market in the early 2000’s, when many companies began labeling products “3-free.” The phrase signifies that the product is free of:

  • Dibutyl phthalate, a plasticizer used to enhance a polish’s texture and function. It has been linked to reproductive and developmental problems.
  • Toluene, a known nervous system disruptor.
  • Formaldehyde, a carcinogen.

Some nail polish companies took things several steps further by removing even more chemicals, labeling their products “5-free,” “10-free,” and even “13-free.” This, however, does little to educate buyers about which chemicals have been removed and which chemicals have replaced them. That is what Young and her colleagues set out to find.

40 Nail Polishes Tested

For the study, the team purchased and tested the contents of 40 nail polishes from 12 different brands, labeled 3-free all the way up to 13-free.

The study didn’t name the brands, but 2 of the tested brands made up a combined 15% of the nail polish market.

Young said:

“We found that the meaning of these claims isn’t standardized across brands, and there’s no clear information on whether these nail polishes are actually less toxic. Sometimes, when 1 known harmful chemical was removed, the polish instead contained another similar chemical that may be just as toxic.”

Most of the 5-free polishes lacked the same handful of ingredients; however, Young and her team found far less consistency among polishes labeled 10-free and above. The brands varied in how they adhered to the claims on their labels.

None of the samples were found to contain dibutyl phthalate. But polishes with a range of labels tested positive for at least 1 of 2 other plasticizers linked with health problems. One polish was found to contain one of the chemicals its label claimed to exclude.

Note: The blue color represents the ingredients that are removed from the product line, according to the label. Potential plasticizer ingredients are underlined. Nonplasticizer ingredients are not underlined. No. of nail polish brands refers to the number of brands that had a nail polish product line with that particular product label. *These two ingredients were reported to count as one exclusion. **Fragrances can contain plasticizer chemicals.

Just because a nail polish claims to exclude multiple substances, that doesn’t mean it’s safer than one that makes no such claims.

The findings applied to some of the most popular nail polish brands in the industry. Though the samples weren’t representative of the entire nail polish market, Young said the findings are relevant to anyone who likes to add a colorful hue to their nails.

Amusingly, some of the nail polishes the Harvard researchers analyzed excluded ingredients that pose no health risks at all, such as gluten, wheat, fat, and “animal-derived ingredients.” You only have to worry about those if you plan on drinking your nail polish. [1]

It’s not clear how much exposure it takes to affect a person’s health, but nail salon employees, in particular, should be concerned about the potential health risks of their job. [2]

Young said:

“This is especially important for the over 400,000 nail salon workers in the U.S. who could be exposed on a daily basis, for many years, to chemicals that have been linked to health effects on fertility, the reproductive system, fetal development, thyroid function, and possibly even obesity or cancer.”

Young and her fellow authors said that nail polish makers should focus more on excluding entire classes of ingredients – including phthalates and organophosphates – rather than individual compounds. [1]

They wrote:

“Then, certified labels could be useful tools for educating nail polish users, nail salon owners, and nail salon workers about toxic chemicals and how to make best purchasing decisions.”

The study was published in 2018 in the journal Environmental Science and Technology – so hopefully things have changed since then. Either way, be reminded that product labels and claims aren’t always so truthful or accurate.

Acetaminophen may Increase Stroke Risk in People with Diabetes

Many people reach for a couple of acetaminophen tablets (acetaminophen is the main active ingredient in Tylenol) for a headache and other minor aches and pains. It’s easy to think that you’re safe taking a drug that is so readily available in pharmacies and supermarkets, but for people with diabetes, taking acetaminophen may increase the risk of having a stroke.

According to a recent study, approximately 5% of people who took acetaminophen suffered strokes, compared to 4% who didn’t take acetaminophen but had strokes. However, people in the study who had diabetes suffered even more strokes.

Study author Philippe Gerard, a researcher at Gérontopôle, Centre Hospitalo-Universitaire de Toulouse, said:

“My personal message to the people in my everyday practice is that any drug they take may have some form of harmful side effect unknown to them, even those they can buy over the counter.”

Researchers conducted the study to explore the link between acetaminophen and cardiac events in older people living in nursing homes in France. In the end, no connection was uncovered.

Overall, the researchers found that acetaminophen is a safe pain reliever for older adults, but people with diabetes should be more wary of taking the medicines containing the drug.

The study concluded with:

“Despite old age, polypharmacy, and polymorbidity, acetaminophen was found safe for most, but not all, of our NH study population. Pain management in NHs is a health priority, and acetaminophen remains a good therapeutic choice as a first?line analgesic. More studies are needed on older diabetic patients.”

It should also be noted that it is remarkably easy to overdose on acetaminophen, and the drug is associated with kidney damage and acute liver failure.

Gerard said:

“It is always best to check with your healthcare provider before you take any new medication, and make sure you’re taking the dose that’s right for you.”

The study was published March 26 in the online version of the Journal of the American Geriatrics Society.

Fat-Shaming Doesn’t Work and Can Increase Health Risks

If you think harping on someone about their weight will convince them to drop some pounds, you couldn’t be more wrong. Not only does it not work, but it may also raise their risk for heart disease and other health problems.

As someone who has battled the bulge, it seems ridiculous to me that anyone would even think that shaming an obese person would have any positive effect. And as someone who has counseled people in 12-step recovery, I can tell you that pressuring someone or making fun of someone with a weight problem – which is often a sign of an eating problem – only makes things worse.

If someone is burying their problems in food, harping on it only makes them withdraw even more into food.

To me, it’s obvious. But plenty of people – too many people – think fat-shaming is effective.

Researchers at the University of Pennsylvania’s Perelman School of Medicine in Philadelphia found that overweight women who believe negative messages about their bodies – called “weight-bias internalization” – had higher rates of metabolic syndrome, a combination of health problems that increase the risk for heart disease and diabetes.

Dr. Rebecca Puhl, deputy director for the Rudd Center for Food Policy & Obesity said that the increased risk shows that weight stigma and fat-shaming “go much deeper than the inappropriate remarks or hurt feelings.” [1]

Overweight and obese people are often viewed as lazy, unattractive, incompetent, and lacking willpower. That doesn’t give heavy people a sense of motivation and confidence; it leaves them feeling hopeless and stigmatized. Depressed, really. And we know that depression can make you physically sick.

Published in the journal Obesity, the study suggests that it’s not just the stigmatizing, but also the level of a person’s reaction to fat-shaming, that can cause health woes.

The Research

Researchers asked 159 adults how much they devalued and blamed themselves when they were stigmatized for their weight. The team also looked at how often metabolic syndrome was diagnosed among the participants.

In all, 51 of the participants met the criteria for metabolic syndrome. Those who felt the most devalued and had the highest levels of self-blame were approximately 46% more likely to have metabolic syndrome. Those participants were also found to be 6 times as likely to have high triglycerides. [1], [2]

People with the highest levels of internalizing devaluation and self-blame – in other words, they really took those nasty words and stereotypes to heart – had 3 times the risk of metabolic syndrome, compared with the lowest-level group.

The study lends support to earlier research, said Dr. Scott Kahan, director of the National Center for Weight and Wellness in Washington, D.C. He said:

“Numerous studies have shown that experiencing weight stigma increases stress hormones, blood pressure, inflammation and ultimately increases the risk of several diseases, including diabetes and heart disease.” [1]

For example, studies have shown that being fat-shamed can cause increased inflammation and stress-hormone levels in the body. People who dislike themselves also have a harder time exercising and eating healthy. [2]

All of that “poking fun” at obese people has also been linked to binge eating, as I mentioned, and premature death.

Rebecca L. Pearl, PhD, said:

“There is a misconception that sometimes a little bit of stigma is necessary to motivate people to lose weight. But time and time again, research shows that this is just not the case.” [2]

So, what does all of this mean? Firstly, that you have to love yourself before you can make positive changes for your health. And secondly, it’s not OK to shame overweight people. And if you’re one of the people being stigmatized for your weight, the problem lies with the person stigmatizing you not you!

Pearl added:

“People with obesity are portrayed in negative ways in the media; there’s bullying at school and on social networks; people even feel judged by family members or in health-care settings.

Rather than blaming and shaming people and being dismissive of their struggle, we need to work collaboratively to set goals to improve health behaviors.” [2]

You Should Still Try to Make Improvements for Your Health

Now, none of this is to say that if you’re overweight or obese, you should stay that way just because you have a positive self-image. Excess weight isn’t healthy. Even if you don’t have health problems now, chances are if you don’t lose weight, you’ll develop them in the future.

If you struggle with your weight and struggle with how you feel about yourself, set small, attainable goals to help you shed the pounds. Give yourself reasons to pat yourself on the back and tangible successes to encourage you along the way.
