Is Hand Sanitizer Safe?

Hand Sanitizer Everywhere

Hand sanitizer is as ubiquitous as handbags. It's used in schools, at home, and in the workplace. But did you ever stop to think if it's really all that great? Sure, millions use it. It is proven to reduce the amount of bacteria on the hands, but digging a little deeper, there could be some interesting things going on....

High Amount of Alcohol in Hand Sanitizer

In order to be effective, hand sanitizer needs to contain at least 60% alcohol. Hospitals tend to use sanitizers with even stronger concentrations of alcohol. But, to effectively kill most bacteria, some fungi, and some viruses, the level cannot be below 60%.

A typical little bottle of the stuff has the same amount of ethanol as 4 shots of vodka. Plus, they make it smell good.

So what's to keep a small child from ingesting it?

It's happened before. A little girl went to the emergency room really lethargic and barely responsive. Blood tests showed normal blood counts and she otherwise showed no signs of disease.

No one could figure out what was wrong until the girl's teacher called and said that she had used hand sanitizer on her hands. The other kids in her class said that the little girl licked the sanitizer off of them.

Doctors immediately started treating for alcohol poisoning.

Some schools have started banning the substance from the lower grades. Some parents have started to lock up their sanitizer, letting children use it only under supervision.

But, there were still 12,000 cases of people ingesting hand sanitizer in 2006, according to data from the Poison Control Center.

Sanitizer is just alcohol, right? Wrong.

Sanitizers have other chemicals in them, too.

This particular brand of hand sanitizer doesn't list benzalkonium chloride, but there are other ingredients I don't recognize.

Benzalkonium Chloride

You hear lots about limiting processed foods, especially those with chemical names you can't pronounce. The same should go for skin. It's the largest organ: it's porous and it absorbs whatever you put on it.

So, just what is benzalkonium chloride? Well, it's really soluble in ethanol and manufacturers often use it in small amounts in hand sanitizers and other antiseptic solutions.

It causes disruption of those lipid bi-layers in cell membranes. That's how it kills the bacteria. But...enzymes in the human body and most organic cells have lipid bi-layers. They are what control how much water, fat and other materials enter the cells.


Add to that, benzalkonium chloride is toxic to mammals if the concentration is high enough. Lower on the food chain, it's toxic to aquatic wildlife and birds, even in small amounts.

I think about how often I use hand sanitizer. Am I inadvertently helping to toxify my environment?


Hand sanitizers often contain fragrances. But, manufacturers aren't required to list exactly what's in those fragrances.

Therein lies the problem.

Fragrances can contain a whole plethora of chemicals.


These are widely used by industries, with a range of applications. In fragrances, they create that oily feel that helps the scent last longer. Anything with a fragrance - hand sanitizers, lotion, hair spray, hair gel, perfume, shampoo, and conditioner - could be a candidate for containing phthalates.

Though they are typically present in small amounts, I have to wonder about the repeated exposure to phthalates. They can hurt cells in the male reproductive tract. They also can potentially make people experience more allergies with more severe reactions, among other things.

I keep hearing stories that the overall human rate of fertility is decreasing (though you may not think so with 7 billion people on the planet). Hmmm.


Remember high school biology and all those animals preserved in it? The smell of formaldehyde is quite distinctive. Fragrances often contain small amounts of this chemical. It is also known to irritate the respiratory tract and the endocrine system in mammals.


In the last couple of decades, triclosan has found its way into soaps, cleaners, toothpastes, and not surprisingly, hand sanitizer, especially non-alcohol-based types.

There are reports that 75% of the US population excretes triclosan in urine because it is so widespread.

The problem with triclosan is that it's antibacterial. On the surface that seems all right, but if you look deeper, it's becoming more associated with bacterial resistance. Thus, we might inadvertently create super-bugs, resistant to antibiotics. Initially, bacteria succumb to triclosan, but there are always a few that are resistant to its effects. Those bacteria are then able to reproduce, despite the triclosan.

It's also associated with being an endocrine-system disruptor. That means human growth and development could be affected by exposure to this particular chemical.

The Verdict

I use hand sanitizers. I am not against them. I am neither a doctor nor a scientist and I haven't personally conducted my own scientific tests to find out everything about these chemicals.

But, I also like to take responsibility for my own health. It's also important to note - again - that other than alcohol and water these chemicals are present in small amounts in hand sanitizers and they are not in every type of sanitizer.

With the prevalence of so many industrial chemicals in water, shampoo, cleaners, and personal hygiene products, I aim to limit my use of hand sanitizers, however. I am not sure how many repeated exposures to these small amounts of chemicals will tip the biological clock to create irregularities in my cellular DNA, but I don't really want to find out.

Do you Regularly Use Hand Sanitizer?

Alternatives to Hand Sanitizers

  • Regular soap and water. Generations of people have used regular soap and water to clean their hands and have done just fine with it.
  • Use natural products whenever you can.
  • Make your own on-the-go hand sanitizer. Get a little bit of dish soap (preferably fragrance and triclosan-free), add water, shake and you have your cleaner. Bring along some napkins and paper towels and you can clean your hands and other objects like toys, car steering-wheels, and anything else you might need to clean on the go.
  • Use a hand-sanitizer with completely readable ingredients. That is, ingredients that you can readily identify without being a chemistry major. You'll be doing yourself a favor. Use the Skin Deep Database, and find ingredients that rank as close to "0" as possible (the lower the better).

      I use hand sanitizer a lot because I'm a teacher and the kids and I are touching the same things. Thanks to your hub, I need to stop and rethink using it so much. I think I'm going to try your homemade sanitizer recipe and keep that on my desk at school - it sounds a lot safer. Thanks for a very helpful hub.

      Hand sanitizes are very bad for daily use, and will retard your immune system.

      In fact according Choice Magazine (a highly respected magazine in Australia similar to USA's Consumer Review) they are so bad that any household using antiseptic hand washes need to do a rethink and stop listening to the latest TV commercials.

      Choice Magazine stated that day to day germs around the home are required to build a good immune system. Without the little bugs in our homes people loose there immunities and this is difficult to reverse.

      Choice went as far as to insinuate that users are fools and now would be a good time to regulate the manufacturers' claims.

      I used it when travelling in Egypt. I figured it was safer than the water. And at most of the public toilets (which in most places were just holes in the ground) there was no water anyway. I was grateful for it there.

      I didn't know this but I do remember hearing how people ingested sanitizer and it pretty much ate their insides. It's one thing to use them when you're not by a sink but I do like the feeling of soap and water. It's just that now everyone's so germaphobic about touching something right after they wash their hands, it seems like people sanitize after washing. I think you're right- you should use them but also use good judgment. Thanks for this valuable information!

      It's funny but just plain old soap and water works better than hand sanitizer! As you point out, an old fashioned hand washing has worked for a very long time. I've also read hand sanitizes aren't as effective as people claim. I generally just don't use them, myself, but one of my coworkers is a hand sanitizer fiend.

      Well, the Verdict summarises the article well. "I don't know anything certain, but I chose to abstain from X"

      You say dish soap solution is better, but it triclosan you warn against is an active ingredient in dish soap. It also contains SD Alcohol 3A and sodium xylenol sulfonate, both suspected to be carcinogenic.

      "...especially those with chemical names you can't pronounce." Thanks for a great advice. You should make sure your cells do not contains the deoxyribonucleic acid.

      MT - I admit I've used hand sanitizer for years, but sparingly. I've always been a little leery, too. Then, when I finally took a hard look at the chemicals it has, I now make my own on-the-go stuff. I know there's not very much really bad chemicals, but I worry about the long-term exposure to it. Great comments and insights. :)

      I never really trusted hand sanitizers - I didn't think they would really work, or they would have to contain strong chemicals to work, and I didn't leave them on my skin. Plus when a new product comes on the market, I like to wait and see its long term reactions before jumping on board, especially when it is a chemical. I'll stick with soap and water.

      ytsenoh - as soon as I researched for this hub, I virtually stopped. I have switched to soap and water. The only time I ever use it anymore is if I can't find anything else and need clean hands: like when I've been to the gas station and then going on a picnic or something like that. But, I'm trying to use a spray bottle with a little bit of dish soap for such occasions. :) Thanks for stopping by!

      I use hand sanitizer as well. I usually only use it when dining out.

However, I have no problem using sanitizer sparingly. Very informative hub and voted up and useful.

      Great article and good information! I have worked in healthcare for over twenty years and sanitizers are great, where it is needed, in hospitals and such! In a normal life there simply is no need for us to use it. I don't use sanitizers at all in my normal life, water and soap is sufficient. We need bacteria on our hands and this phobia for bacteria has gone too far. Wonderful hub, voted up, useful and shared!
