Experts agree that one of the easiest ways to avoid spreading germs is to wash your hands, particularly prior to eating. However, sinks and bathrooms are not always available. This has prompted children’s gyms, party centers, schools, and parents to provide hand sanitizers for children since they are prone to putting their hands in their mouths as well as touching things that, well, they shouldn’t.

Contact with surfaces such as playgrounds, doors, and tables can play a role in catching a cold or the flu, and just cleaning those surfaces is not enough. The next time someone with a cold touches that surface, the germs will once gain be present. The solution is frequent hand-washing or the use of hand disinfectant. In the US alone, hand sanitizer sales have grown from $50 million to $150 million since 2002.1

However, hand sanitizers do have their critics. An associate professor at Purdue University states manufacturer’s claim 99.9 percent of bacteria are killed because the product is tested on inanimate surfaces such as desks—not on human hands.2 Since testing hands would be more difficult, manufacturers use surfaces with controlled variables to obtain consistent results. Even the Centers for Disease Control (CDC) states they were unable to find a product that met their label claims of 99.9 percent.3

Triclosan
In addition to the exposure to alcohol-based hand sanitizers, children also come into contact with antibacterial products made with triclosan. Triclosan is registered with the EPA as a pesticide4 and is used in a wide variety of products, including soap, lotions, laundry detergent, dishwashing liquid, and some toothpastes.5 Triclosan is used to kill bacteria on the skin and other surfaces and sometimes is used to preserve the product against deterioration due to microbes.6 Many scientists now believe that triclosan is not necessary most of the time, and they also believe that it can contribute to the rise of drug-resistant bacteria.7

Acute and chronic effects of triclosan include skin irritation, photoallergic contact dermitis, possible thyroid issues, and allergic reactions. In addition, researchers at Virginia Polytechnic Institute and State University found that under normal household conditions, products containing triclosan react with chlorinated water to produce chloroform, which is a probable carcinogen.8

A Swedish study found high levels of triclosan in 60 percent of breastmilk samples tested.9 Triclosan and other pesticides can also be absorbed through the skin.

Germ-Free Kids
The “hygiene hypothesis” theorizes that there is a link between being too clean and increased allergies and asthma. Studies have found that people raised in more sterile and hygienic environments actually increase their chances of allergies, asthma, and eczema.10

The CDC states that using antibacterial products could alter a person’s microflora and affect the normal development of the T-helper cell response of the immune system. They believe this change leads to greater chance of allergies in children.11 In addition, our immune system gets stronger if it is challenged, and not challenging it enough could lead to more frequent illness.12 The CDC urges us to use these products sparingly and remind us that the original purpose of these products was to protect vulnerable patients.

Essential Oils
Essential oils have been around for centuries and are even referred to in the bible as a way to cleanse and heal. But does this apply to modern times? Published research does seem to support the efficacy of essential oils. In fact, a study published in 2006 examined the effectiveness of 21 essential oils on six bacterial species. Out of 21 essential oils tested, 19 oils showed antibacterial activity against one or more strains. Cinnamon, clove, geranium, lemon, lime, orange, and rosemary oils showed the most promise13 , and are one of the reasons for the growing belief of their effectiveness in protecting the human hand against bacteria. There are several patents for antimicrobial products, in which essential oils are used as the antimicrobial agent.14,15,16

Staph Infections
In a 2004 study, the biology department at the Manchester Metropolitan University researched patchouli, tea tree, geranium, and lavender essential oils as well as Citricidal (grapefruit seed extract). These oils and extracts were used alone and in combination to assess their anti-bacterial activity against three strains of Staphylococcus aureus. A combination of Citricidal and geranium oil showed the greatest anti-bacterial effects against methicillin-resistant Staphylococcus aureus (MRSA), while a combination of geranium and tea tree oil was most active against the methicillin-sensitive S. aureus (Oxford strain). The researchers concluded that the study demonstrated the potential of essential oils and essential oil vapors as antibacterial agents and for use in the treatment of MRSA infection.17

Protection against Food-Borne Pathogens
One study published in the Journal of Applied Microbiology looked at the effectiveness of essential oils against a number of common food-borne pathogens. Results suggest the possibility that citrus essential oils, particularly bergamot, could be used as a way of combating the growth of common causes of food poisoning.18

Head Lice
The Archives of Dermatological Research published a study in 2007 that demonstrated the effectiveness of essential oils on head lice and compared them to commercially available products marketed to treat lice. A lotion combination of lavender, peppermint, and eucalyptus provided the best results and were comparable to the best commercial product available on the market.19

Stress
In a study published in Holistic Nurse Practice in March 2008, nurses working in the intensive care unit perceived lower levels of stress with the use of lavender essential oils.20

Take Action
A visit to your local health food store will provide you with an abundance of ways essential oils are being used today—from shampoos to hand sanitizers. Or if you prefer, look into the straight essential oils. They provide a good alternative to harsher chemicals that are available on the market. If you or your child is sensitive to chemicals, these are definitely worth a try. Therapeutic-grade essential oils can be ingested (in small amounts) and are widely available. Given the research supporting essential oils, the growing trend of essential oil hand sanitizers certainly seems justified. For regular hand-washing, plain old soap and water is recommended.

Resources
The Complete Book of Essential Oils and Aromatherapy: Over 600 Natural, Non-Toxic and Fragrant Recipes to Create Health – Beauty – a Safe Home Environment by Valerie Ann Worwood provides a good overview and solutions for using essential oils at home.

EO and Cleanwell both make essential-oil-based products and are widely available. They can also be purchased in bulk for school settings.
