Classroom Diffusion – the Concerns, FAQs, and Safe Ways to Use Essential Oils

Classroom diffusion is an increasingly important safety topic to address. While teachers aim to diffuse to reduce the incidence of illness and spread of germs in their classroom, or diffuse “calming” or “focus” blends to mediate classroom teaching, active diffusion during class has myriad safety concerns.

 

Here are the 5 main concerns:

  1. Are the oils used appropriate for age?

According to the latest safety recommendation from Tisserand and Young (2014), certain essential oils known for their high antimicrobial and antiviral activity may increase the risk of adverse reactions. These oils tend to be marketed as germ-fighters. A common list of such oils and their contraindications include:

  • Cinnamon – contains the constituent eugenol, which is hepatotoxic, meaning it may cause damage to the liver. Overdose is possible, particularly around young children with immature livers, causing a wide range of symptoms from blood in the patient’s urine, to convulsions, diarrhoea, nausea, unconsciousness, dizziness, or rapid heartbeat. In general, irritation, over-stimulation and physical discomfort is possible from over-exposure via inhalation.
  • Clove – contains high levels of eugenol, approximately 80-90%. In general, irritation, over-stimulation and physical discomfort is possible from over-exposure via inhalation.
  • Eucalyptus species and 1,8-cineole-rich oils – eucalyptus oils generally contain high levels of 1,8-cineole, a constituent known for triggering respiratory distress especially in those with compromised respiratory systems. Tisserand and Young (2014) recommends to avoid use on or near the faces of children 6 years and under.
  • Peppermint, cornmint, and other menthol-rich essential oil – menthol is known to stimulate cold receptors in the lungs, and this triggers a reflex in young children which slows down breathing significantly, and sometimes dangerously.
  • Rosemary and camphor-rich oils – rosemary also contains 1,8-cineole, as well as camphor. Camphor is known to trigger seizures in those suffering from epilepsy.

 

  1. Has health assessments and contraindications been checked for each student in the class?
    As per above, essential oils do pose safety hazards for those with medical issues. Diffusing without parental informed consent – “informed” meaning parents are fully aware of contraindications of essential oils selected – may cause harm, and is also akin to providing medication without permission from parents and the appropriate health professional. Other health considerations include: asthma, ADD/ADHD/autism, chemical sensitivities, immune-compromised, and medications. Different essential oils are known to trigger different reactions in asthmatics, so caution must be taken for all oil-use. Oils such as lavender and chamomile, while generally calming/sedating, has been documented to have the opposite effect on children and adults with ADD/ADHD/autism. Any fragranced oils including essential oils can be highly-irritating to those with sensory processing difficulties and chemical sensitivities. Certain essential oils have also been documented to interact with medication.

 

  1. Are the oils being diffused constantly?
    According to research, constant diffusion is ineffective at best (habituation effect) and increases risks to sensitisation at worse. Over-exposure to fragrances including essential oils can cause headaches, nausea and light-headedness. Safety recommendations are 30 minutes on and 60 minutes off for best results with minimal risks, with open air-flow, for a water-type or ultrasonic diffuser. For nebulising diffusers that emit pure essential oil into the air, the recommended diffusion time is 10 minutes, 2-3 times a day for adults. For children, reduce the amount of time diffused.
    However, contraindications and at-risk populations must be noted – safe times for diffusing would be before and after school hours when no children are present. For amounts to diffuse, this depends on the type of diffuser used. Follow the instructions included with the diffuser, or the essential oil bottle.

 

  1. Are we causing more long-term harm by mediating developing immune reactions with strong antivirals and antimicrobials?

According to a recent article by Lauren Bridges (2017) published on Tisserand Institute, overuse of strong antimicrobials may inhibit immune system development in young children, as well as risking sensitisation, overexposure to stimulating oils and possibly contributing to bacterial resistance. Other effective aromatic options with better safety profiles, is recommended.

 

  1. Is diffusing in compliance with policies? Are there legal concerns?

Schools generally have policies on the use of fragrance, and this includes essential oils. There may also be legal concerns around causing harm through diffusing essential oils without informed consent from parents or consultations with a child’s medical practitioner.

 

FAQs:

  1. Aren’t essential oils natural and better than fragrance plug-ins or chemical sprays?

Although essential oils are derived from plants an are thus considered natural, versus synthetic fragrances, side effects such as nausea, light-headedness and headaches have been documented with overexposure. Contraindications with medical conditions and medications have also been documented. Essential oils have the potential to both help and harm, so risks and cautions must always be considered when using essential oils.

 

  1. What if I source essential oils from a trusted company?

While purity of essential oils is important, pure essential oils, regardless of company or marketing spiel, pose risks and adverse reactions, based on their chemical constituents. Cautions, contraindications and safe use must be considered for all essential oils.

 

  1. My child’s classroom is diffusing essential oils and I am concerned about reactions. What do I do?

Refer to your school’s policies on fragrances and medications – most schools prohibit the use of fragrances due to chemical sensitivities, and medications require prescriptions from medical practitioners. Refer to the school’s Complaints Policy as well for procedures to guide you in raising your concerns. Consult your medical practitioner if you have concerns about your child reacting to essential oil diffusion. Print off this information sheet to include in your case.

 

 

Recommendations:

  1. Personal inhalers – individual personal inhalers for teachers is a safer option if they wish to support their immune system.
  2. Diffuse before and after school hours, when children are not present. Follow dosage amounts on essential oil bottle and instructions for diffuser equipment.
  3. Reminders for Hygiene practices – handwashing, cough etiquette, wiping surfaces, enforce quarantine periods
  4. Consult a clinical aromatherapist or IAAMA (Australia’s International Aromatherapy and Aromatic Medicine Association) if you as a parent or a school has further concerns.

Making Aromatherapy Sprays

 

Aromatherapy Sprays are a simple and effective way to use essential oils to cool you down and help refresh yourself physically and energetically. You can also use them to freshen the air in a room, or from an energetic perspective,

clear any lingering negativity.

Here is how you can make Aromatherapy Sprays at home.You will need:

  1. A spray bottle with a spray nozzle. You can purchase these easily online nowadays – some recommended companies in Australia are here and here. I like them because of the affordable pricing and also no minimum order. You can also purchase small spray bottles from most supermarkets too – these are usually aluminum bottles with a trigger spray, about AUD$2.50.
  2. Essential oil(s). You can use a single oil, or a blend of several essential oils. If you are a newbie, start with a single oil, or a blend of 2-3 oils. Make sure you  have no sensitivities to your selected oils. If you are using around babies and children, make sure you are using kid-safe oils. You can find information on this here.
  3. Cooled boiled water or distilled water
  4. A dispersant: oil and water do not mix, so to make sure your mix does not leave you with undispersed droplets of essential oils on sensitive skin, a dispersant is preferable. You can use a “solubaliser” (this is available from the companies I linked in number 1, or some health stores that also sell essential oils), or ethanol/high-proof vodka. For the occasional home user, you can use plain castille soap.
  5. A preservative: this is highly recommended, because water is a great medium for growing nasties like bacteria, mold and fungi. Even distilled water from a brand new bottle, can grow those nasties if left long enough. You can purchase a preservative from one of the companies I linked in number 1. Ethanol/high-proof vodka is also a preservative at 40% of your final product. You can opt not to use a preservative, but be mindful to use your spray within one week, or store in the refridgerator and use within 2-3 weeks. This is where I recommend using a smaller spray bottle, something that is about 50ml, so you don’t end up throwing product away.

Okay, let’s get started!

For a 50ml bottle:

Step 1: Add 20 drops in total of essential oil(s) into the bottle.I have provided some formulas for essential oil blends below.

Step 2: Depending on your choice of Dispersant, add 10-20 drops of solubaliser, OR 2-3 drops of castille soap. If you are using ethanol or high-proof vodka, add 20ml.

Step 3: If you are using a Preservative, follow the instructions for use. Most effective preservatives on the market require 0.5-2% of the total volume, so essentially you would be looking at 5-40 DROPS of preservative in your 50ml bottle. You can find effective preserving systems that are considered natural in the cosmetics industry, so not all preservatives (chemicals) are bad for you! However, cosmetic products that do not have effective preservative systems CAN harbour dangerous bacteria, mold or fungi, and I can tell you antibiotics to treat THOSE are worse than preservatives. If you are using ethanol or high-proof vodka as your solubaliser, it will do the job of preserving your spray, although I would still put a short shelf-life on it.

Step 4: Swirl, then top up with cooled boiled water or distilled water. Put the spray nozzle on, shake well, and spray about you or around your space.

Some Formulas for Essential Oil Blends:

Sleepy night:

10 drops lavender

5 drops bergamot

5 drops geranium

Monster repellent:

5 drops petitgrain

5 drops cedarwood

5 drops lavender

5 drops geranium

Clearing Negativity:

5 drops juniperberry

5 drops peppermint

5 drops lemon

5 drops black pepper

To fill a 100ml bottle, double the recipe above.

*Be aware that some people may be sensitive to alcohol on the skin, so watch out for sensitivities. If you are using alcohol, not spraying directly on sensitive facial skin is a good idea.

SOME FREQUENTLY ASKED QUESTIONS:
1. Aren’t essential oils antiviral and antibacterial? Won’t they preserve the product?
No, because although their antiviral and antibacterial properties are effective against infections on the skin and in growth mediums, they do not extend to preserving a whole product. Add to the fact that oils and water do not mix, essential oils’ antiviral and antibacterial properties do not extend to the water phase. Using higher concentrations of essential oils, say 20-25% may act to preserve the product, we are then looking at possible skin sensitisation at those levels, as well as the economics and sustainability of it (25% of 50ml is 12.5ml of essential oils!)

2. My oil company says our oils are so pure that they dissolve in water
Pure or not, essential oils are volatile organic compounds made up of mainly hydrogen and carbon atoms. Most of these molecules are hydrophobic – meaning they do not mix with water. SOME parts of the molecules may dissolve in water, but the majority will not. It is why when you leave your oil and water mix for a while, the oil settles at the top of the water. Shaking the crap out of it will help mix it up, but not fully. The oil and water will eventually separate. Shaking it before use each time can minimise skin sensitisation, but if we are using essential oils that are phototoxic, or contain skin-sensitising molecules, we may still get droplets of essential oils on our skin, which may harm us. For example, we use lemon essential oil or limonene compounds in spray products to degrease surfaces. If they are effective enough to degrease surfaces, they are effective enough to affect our skin, which is made up of lipids (fats).

3. My oils are so pure, they cannot cause sensitisation. Some detoxing may occur, but it is not sensitisation.
Skin sensitisation is very real – it can also happen with essential oils that are generally known as safe, like lavender or chamomile. Skin sensitisation can occur in your first use, or it can occur after prolonged and repeated use, safely diluted or not. While purity is important, and skin sensitisation is more likely to occur with adulterated oils or oils that have been poorly stored leading to oxidisation, people have reported sensitisation to pure essential oils. Once sensitisation occurs, it is likely you may not be able to continue using that oil, and in serious cases, it can extend to other essential oils that contain similar chemical constituents as the one you are sensitised to. So my perspective is, keep to safe dilutions, regardless of purity, so you can continue to use those essential oils. You can read more about sensitisation here, here, and here.

4. Can I use honey as a dispersant and preservative?
No. Although honey is antibacterial, its properties do not extend to preserving a product, especially one that contains water. When honey is added to water, it is actually a sugary environment perfect for bacterial growth. While it CAN help disperse essential oils, you will still need a really good preservative. Read this blog as it explains it so much better than I (the bloggist is a cosmetic formulator highly regarded in cosmetic formulation circles).

5. Can I use Epsom salts, glycerine or bicarb soda as a dispersant?
Some older aromatherapy texts do suggest Epsom salts, glycerine or bicarb soda as a dispersant. While these changes the “wetness” of water, meaning they weaken the water bonds so they may “blend” better with essential oils, they are still not effective dispersants. Personally, for home use to make aromatherapy sprays, they may be adequate substitutes, because you are not using high amounts of essential oils and you are not spraying profusely. Just avoid spraying on sensitive facial skin or on children and babies. If you wish to read more about dispersants, this is a good article written in by the Tisserand Institute in partnership with Deborah Kallevig, a cosmetic formulator. The article is specifically about dispersing essential oils in bath water, but it explains beautifully how to effectively (and not) disperse oils in water.

I hope I have not scared you off making aromatherapy sprays, after all of those cautions! It seriously is a simple process, granted more simple than the safety considerations, but I truly wish to leave you with the idea that essential oils are wonderful and therapeutic CHEMICALS that can heal AND harm. Simply be aware of risks, and aim to use essential oils safely, and you are good to go! If you have any questions, feel free to ask/comment, I will do my best to answer.
