Sanitizer

Updated February 21, 2022

When considering agents that kill bugs like the coronavirus, the usual factors are the concentration of the agent (how strong), and how long the “contact time” is needed to kill (“virucidal”) the bug. In general, the stronger the concentration, the less the contact time needed. Usually. the stronger the concentration, the more aggressive the product is on the skin or tissues.

Alcohol (isopropyl or ethyl ) can kill the coronavirus in approximately 1-2 minutes at 60-70% strength. It kills faster at higher strengths but this is more difficult for the skin. Once evaporated, it has no residual effect. Re-innoculation can occur seconds after.

By damaging the skin while killing the virus, other problems can arise, such as rashes, cracking, and wounds.

The ideal sanitizer should have at least 4 characteristics:

  1. It should kill any existing bugs as efficiently as possible;
  2. It should not damage the underlying tissues or surfaces;
  3. It should provide continued protection for a period of time after application;
  4. Be usable not just for hands but also nostrils.

Unfortunately the commercial sanitizers only meet the first criteria. The gelling and coloring agents and fragrances do not really add much benefit, and can have some negative chemical effects.

The proposed sanitizer ingredients listed below can to enhance the function of what is being sold. Iodine is effective against past coronaviruses (SARS and MERS), and can be superior to hand washing even in dirty conditions (see Coronavirus Research above). In addition, several essential oils, including cinnamon, eucalyptus, oregano, peppermint, rosemary and tea tree have proven effects at relatively low concentration and contact time.  The carrier oils, olive and sesame, have some antiseptic effects and are better/safer for the skin rather than the gels. Finally, by lingering on the tissues, they can provide extended protection.

After spraying the hands, a tissue can be used to wipe the entrance to the nostrils, both to kill and to protect.


Sanitizer ingredients (organic if/when feasible):

> 63% ethyl alcohol (higher levels are harder on the skin and do not provide much more protection; the below ingredients are intended to augment the effect of the alcohol

> 200 ppm Iodine

> 1.00% maximum blend of oils of cinnamon, clove,  eucalyptus, peppermint, rosemary, tea tree and thyme

olive oil

sesame oil.


Sanitizer Instructions

  1. Separation means less chemicals! Shake well before use.
  2. Real essential oils may affect skin, plastics, eyeglasses and other surfaces — test on small area before using.
  3. Spray and rub hands.
  4. Spray a tissue and wipe entrance to nostrils.
  5. You can also lightly spray the inside of your mask.
  6. Best to use within 60 days of manufacture.
  7. Can be further enhanced under practitioner supervision with other agents.
