9 Reasons You Want to Avoid Hand Sanitizers

Antibacterial hand wash and sanitizer can be very hazardous to your health.

Antibacterial hand wash and sanitizer can be very hazardous to your health.

     Antibacterial washes and wipes seem to be in every classroom nowadays. Media, public health announcements and teachers are constantly admonishing our kids to wash their hands to prevent the spread of illness, but could this constant use of antibacterial chemicals actually be causing more harm than good? And how does it correlate to autism?
     I am definitely a fan of hand washing, but in my house we use old-fashioned castile or coconut oil soap. In fact, even the FDA back in 2005 concluded that washing your hands properly with regular soap and water is just as effective at ridding your hands of potentially hazardous pathogens as antibacterial soaps. With waterless hand sanitizer, even more of the chemical ingredients are absorbed through the skin. When my kids were young, I sent my own homemade, natural, antibacterial waterless sanitizer to school with them, so that they would not be forced to use the commercial ones provided by the teachers.
     So what is the harm in antibacterial washes?

  1.  Muscle weakness/impaired mitochondrial function. Over 76% of antibacterial washes contain the ingredients triclosan and/or triclocarban. (These toxins can also be found in many toothpastes, deodorants, antiseptic and burn creams, dish soaps, dehumidifiers, floor mops, flooring, food warmers, and mouthwashes as well as plastic kitchen utensils, computer keyboards and mice, shoes and sandals, and toys labeled as “antibacterial” or using the trademark Microban®.) They are rapidly absorbed through the skin and have also been shown to inhibit both skeletal and cardiac muscle function at a cellular level. Mitochondria are the powerhouse or energy production source within our cells. Babies and children who have mitochondrial weakness or vulnerability who use these chemicals can suffer mitochondrial dysfunction or impairment because these chemicals interfere with the fluidity of the inner mitochondrial membrane.
  2. Excitotoxins that cause death of brain cells. Studies of triclosan at U.C. Davis found that it attaches itself to the receptor molecules on the surface of brain cells and causes the calcium levels inside the cell to rise, so that the cells become overexcited, resulting in cellular death. This overexcitation can impact mental development and behavior, particularly among those most vulnerable—children with developmental delays and autism.
  3. Allergies and altered brain function. Studies have shown that memory T-cells, critical to normal immune system function, develop by contact with pathogens. An immune system without proper exposure is at greater risk for allergies. For this reason, the CDC has issued warnings that overuse of antimicrobial washes lead to allergies. Normal immune development is also integrally related to normal neurological development. In fact, germ free mice, born by cesarean section and raised in “clean rooms,” had altered expression of three genes involved in mood, anxiety behavior, learning and memory. Studies have also shown triclosan to depress the central nervous system.
  4. Autism incidence correlation. The impact of these chemicals on the genes whose expression correlates with autism  is why U.C. Davis researcher Dr. Isaac Pessah named triclosan (and related compounds with similar properties) as a prime suspect among environmental factors that might cause autism. Through epigenetics (the study of how toxins in our environment affect gene expression) we know that the genetic expression that correlates with susceptibility to autism can be directly altered by toxic exposures that impact expression of these genes.
  5. Dangerous hormonal changes. Both triclosan and triclocarban have been shown to be endocrine disruptors. Triclosan can bind to receptor sites in the body and block normal thyroid function. Endocrine disruptors have been correlated to childhood obesity, type II diabetes and a host of other chronic health problems. Triclocarban has been found to have a new type of hormone altering action. It reacts with and enhances the effects of testosterone and estrogen already being produced in the body. Even one bath with soaps containing these chemicals provides the same body weight dose of chemicals given to rats in experiments that demonstrated significant hormonal changes. These alterations can lead to reduced fertility in men and woman, early puberty in girls, and increased testosterone that has been associated with heightened aggressive behavior in boys.
  6. Bacterial resistance. Use of antibacterial washes can lead to development of resistant bacteria. They kill off friendly bugs that protect us from infection. The CDC did a study that found triclosan in urine of 75% of Americans aged 6 and older. Those levels undoubtedly have a correlation to the increase in strains of resistant bacteria on and in our bodies and our environment.
  7. Alcohol hazard. In addition to the surge in alcohol poisoning cases among teens abusing hand sanitizers reported by hospitals last spring, small children can also be at risk. While not looking for a “high,” hand sanitizers with “goofy grape” and other tasty sounding flavors have been ingested by children, resulting in acute poisoning. Additionally, since we know that young children are apt to put their hands in their mouth, the high content of alcohol in many antibacterial washes can be dangerous to them. According to toxicology expert Dirk Lackenmeier, even a small amount of ethyl alcohol from hand wash in the mouth can cause disorientation, headache, stomach ache and dizziness in a child, and is also associated with increased risk of oral cancer. In addition, if a child has cuts, the alchohol will be much more readily absorbed directly into the blood stream.
  8. Other additive hazards. Many washes also contain dyes and other ingredients that can be absorbed through the skin and cause allergic reactions and sensitivities that lead to behavioral reactions in children.
  9. Harm to our environment and future generations. Triclosan is now being found in breast milk and in waterways and having an effect on the ability of fish to swim in a normal manner. Americans dump more than 1 million pounds of triclosan and triclocarban into oceans, rivers, lakes and streams every year.

So if they don’t provide benefit and carry so much potential harm, why use them? I highly recommend you check the labels on any product that is labeled “antimicrobial” or “antibacterial,” and add triclosan and triclocarban to your list of banned items, especially if you are pregnant or planning to become pregnant.
I sent a small travel bottle of castile soap with my children so they wouldn’t have to use the antibacterial soaps at school, but teachers are lining up students and pumping chemical-laden, waterless hand sanitizer onto their hands now. I learned a recipe  for alternative, homemade, waterless hand sanitizer to send to school with my kids from my pediatrician, Dr. Lawrence Rosen. For that recipe, click here. I have sent this homemade hand sanitizer in a small travel bottle to school with a note saying my children were sensitive to the chemicals in commercial sanitizer. To me, the peace of mind was worth any risk involved in being labeled that “nutty health mom.”

  1. Great article! Thank you for the information. Question, do you know if there are there any companies that have a safe option for commercial use (schools, business, etc.)? It is definitely something that I am interested in initiating and I am working with a high school senior as her mentor with this as her senior project. Thanks for you help!

    • What a great idea for a senior project! Commendations to you! I believe there are starting to be a variety of companies producing safe or safer options. In fact, there are two that were mentioned in comments after yours. I’ve always preferred to just make my own because it’s so easy and so much more economical. I have no personal experience or connection with the following product, but the ingredients look safe and they make dispensers for classroom use give discounts to schools, etc., so for your purposes, it may be ideal: see http://www.cleanwelltoday.com/school/
      Best of luck to you and your mentee! I’d be interested to know how it goes.

    • Sorry you feel that way, Lesley. I was not attempting to represent anyone else’s article. Most of these are scientific studies that provide the evidence for the points I chose to make in my post. That is why I listed them as references.

  2. magnificent points altogether, you just received
    a emblem new reader. What might you suggest in regards to your post that
    you simply made some days ago? Any sure?

  3. I just can’t believe that this mis-information gains so much traction?
    It defies logic, especially in an enlightened world – which we all believe we contribute to! Perhaps we’re just not that enlightened?

    This information is full of errors on so many levels!

    Can anyone else see the irony?

  4. I guess every NICU my boys were in where we, nurses and doctors had to use hand sanitizer every time we touched them was wrong? Hmmm.

    • Unfortunately, so many practices that are held up as safe and prudent at one time are found to create problems later–especially when commercial profits are involved. We can all laugh now at the Chesterfield cigarette ads that advertised how more doctors smoke that brand than any other, but there was a time not very long ago when doctors used to promote cigarette smoking as a healthy habit. Even today I see more health care workers smoking outside our local hospital than outside any other building in the area. Hmmmm….

  5. Your conclusions really stretch the data from your citations to the absolute limit of plausibility. This work is suitable for a basic English composition class, but doesn’t qualify as science.

  8. It’s what I’ve said since this hand sanitizer craze has started.. they are not good for your health. You need to build up resistance to bacteria, or they will kill you. This is especially true for children.

  9. very interesting, I never use the bacteria killing stuff, believe that we need to build up resistance naturally

    • I agree in principal, but in practice, you can’t simply develop a resistance to some lethal bacteria. Campylobacter (common but not the most deadly) brought me to within one week of potentially fatal dehydration, I dread to think what would have happened if I’d not been fit and well before contracting it. This is just one example of why we should be using hand sanitizers, even if we were to make the assumption that all the above points are correct.

  10. The title of the article should not be “hand sanitizers” because the article is not about Purell, etc (though it briefly touches ethanol ingestion). It’s about antibiotic-containing soap.

  11. It is my understanding that FDA regulations do not allow the use of triclosan in leave-on products like hand sanitizer, so that seems to knock out most of your arguments. Do you have any studies that support the germ-killing abilities of your homemade version?

    • You should read up on FDA regulations and the dirty deeds that this Federal organization is currently working on to further the profits and agendas of the corporate elite.

      • Irrelevant to the fact that triclosan isn’t allowed to be in hand sanitizers, and that this article is fully based on the idea that hand sanitizer contains triclosan. Still waiting for the author to provide evidence of her homemade version’s germ-killing abilities.

  12. I’m gone to convey my little brother, that he should also pay a visit this web site on regular basis to take updated from most up-to-date information.

  13. All of your references to triclosan are irrelevant, considering it’s also found in many hand soaps.

    The immune system hypothesis is unfounded, with no research supporting it.

    What isn’t correlated with autism these days?

    Bacterial resistance to hand sanitizer is another widespread myth – it is impossible for bacteria to “evolve” against alcohol, given the nature of its destruction of the microbes. This is, however, a great example of scientific illiteracy, and taking what one person says at face value. Absolutely no cases of bacterial resistance have come out of hand sanitizer use, and in fact, alcohol rubs have actually been shown to decrease the prevalence of anti-biotic resistant bacteria such as MRSA.

  16. My moto is if you wouldn’t eat the product don’t put it on your skin!
    The people who think that these products are safe are either working for them or idiots 🙂

  17. We are a gaggle of volunteers and starting a new scheme in our
    community. Your website offered us with useful information to work on. You have done an impressive activity
    and our whole neighborhood shall be thankful to
    you.

  21. Great blog. I have worked in natural foods, holistic living for the past 8 years and I feel the same. I’ve heard about the dangers of these products for a long while. It’s interesting that the people who disagree with you are very quick to anger. People should be capable of representing their position in a clear and civilized manner, especially if it’s something they whole-heartedly believe. If people had more respect for themselves and others, the world would be a lot better off. I’ll be following your article.

  23. This is a WONDERFUL article! Any tips on how to address this issue at a school, with a child who has autism? Just so you know, our school is “green” and has a sustainability mission – this aspect SHOCKS me but I don’t know what to do about it.
