The best antimicrobial efficacy can be achieved with ethanol (60 to 85%), isopropanol (60 to 80%), and n-propanol (60 to 80%). The activity is broad and immediate. Ethanol at high concentrations (e.g., 95%) is the most effective treatment against naked viruses, whereas n-propanol seems to be more effective against the resident bacterial flora. The combination of alcohols may have a synergistic effect. The antimicrobial efficacy of chlorhexidine (2 to 4%) and triclosan (1 to 2%) is both lower and slower.<\/p>Kampf G, Kramer A. Epidemiologic background of hand hygiene and evaluation of the most important agents for scrubs and rubs. Clin Microbiol Rev. 2004 Oct;17(4):863-93, doi<\/a><\/cite><\/blockquote>\n\n\n\n WARNING: Never bring alcohol with such high alcohol content into a house with an alcoholic. Drinking such concentrations can be deadly, since humans can’t process such concentrations. <\/p>\n\n\n\n Vodkas and other spirits contain ethanol but is too small concentrations to kill all bacteria and viruses. Vodkas start with a minimum of 37%, most being 40-45% ethanol, which is not enough. The percentage will say on the front or the back of the bottle. In a lot of countries, drinks with such alcohol percentages are illegal<\/p>\n\n\n\n This type is a mix of ethanol and processed methanol, which is toxic. <\/p>\n\n\n\n Though there are a couple of essential oils that have been proven to be anti-bacterial, but they are not a good UNIVERSAL kill all ingredient. Let’s see why.<\/p>\n\n\n\n ANTI-BACTERIAL: it kills bacteria like E-coli, food poisoning, wound infections… In “folks medicine” these terms are often used as synonyms – but they are not. <\/strong>Most studies look at bacteria and essential oils, and there needs to be more research. <\/p>\n\n\n\n What is ANTI-MICROBIAL then? Microbe nowadays gets to be used as a general term for anything yucky that might make us sick. However not all microbes are bad, as not all bacteria is bad. Microbes are bacteria, fungi and other, plus maybe viruses, depending who you ask. So if you are looking at a study claiming an ingredient is anti-microbial, check their definitions and exclusions. <\/p>\n\n\n\n Soap kills stuff very well. It’s crazy to believe something as simple and basic as soap can be that effective. But we are making a homemade hand sanitizer with essential oils now, so let me stay focused. <\/p>\n\n\n\n Excellent article here<\/a> and a shorted condensed 4 point version below. <\/p>\n\n\n\n ANTI-VIRAL is not equal to VIRUCIDAL. Anti-viral means the virus just stops reproducing and virucidal means sth. kills the virus. When we are making a hand-sanitizer at home, or buying it in the pharmacies (when available), we are looking to make it virucidal.<\/strong><\/p>\n\n\n\n We actually know very little about essential oils and viruses. Most research with EO has been on skin conditions caused by viruses. <\/strong><\/p>\n\n\n\n Another problem: all viruses are different and respond differently <\/strong>to different environments and ingredients. <\/p>\n\n\n\n In vitro research (in a test tube) doesn’t represent real life.<\/strong> More tests are needed.<\/p>\n\n\n\n In addition, essential oils can be very irritating for some people (immediately or with prolonged use), so be mindful. in case of irritation, stop using the hand gel and\/or decrease the quantity.<\/p>\n\n\n\n Plant medicine is a very potent, however, the potency and efficacy of an individual plant varies based on mode of extraction, meaning drinking tea, essential oils, distillation, maceration… all produce a different result. The region or growth, quality and preservation all effect the final result.<\/p>\n\n\n\n This doesn’t means essential oils have no place disinfecting formulas. Especially in homemade formulas, they round up the formula making it more effective (especially if you are making the concentration of alcohol closer to 60%), have beneficial aromatherapy benefits and act as a preservative, though the alcohol should be concentrated enough to prevent spoilage. <\/p>\n\n\n\n For a general diy hand sanitizer formulating based on essential oils could be enough, but isn’t DEFINITELY NOT ENOUGH when dealing with viruses. <\/p>\n\n\n\n TEA TREE: Tea tree is one of the more studied essential oils and has been proven<\/a> to be anti-fungal, anti-bacterial and anti-viral for some viruses.<\/p>\n\n\n\n OREGANO source<\/a><\/p>\n\n\n\n CLOVE source<\/a><\/p>\n\n\n\n Potentially also lavender, basil, clary sage, and arborvitae. <\/p>\n\n\n\n for 100 ml (3.4 oz)<\/p>\n\n\n\n Shake vigorously and put in a spray bottle. This formulation would last a long time – alcohol kills.<\/p>\n\n\n\n My hands are currently not dry with this formula (I will update in the winter). I use this sanitizer every time I go out, but I do not use it constantly like nurses or shopkeepers would). <\/p>\n\n\n\n I like to use a spray, I find it easier and it leaves no gluey residue on my hands. I can then also just spray down a table, door handle or spoon at a cafe for example. I make a fresh refill every time I need it, possibly at a 2 week mark, depending on what I’m doing.<\/p>\n\n\n\n I use a thin glass bottle, repurposed from my old deodorant which fits into my purse or basket well.<\/p>\n\n\n\n I love working with xanthan, it’s a very funky fun ingredient, but it might cause you some trouble if you aren’t used to it. <\/p>\n\n\n\n Mix alcohol and aloe (or water). Sprinkle xantham gum in the water (or aloe) and gently dap it around to moisten it evenly. Wait for about 5 min for xanthan to re-hydrate. If you mix too fast, you will get a lumpier gel. You will see xanthan expand and then you whisk or mix vigorously (if you do not have a small whisk). Wait a couple more minutes and whisk some more. <\/p>\n\n\n\n Note that aloe vera is there for moisturizing effect, not thickening. It might make your hands a bit sticky, depending on which brands you use. I have tried fresh and bottled aloe vera gel and didn’t find it as moisturizing to be worth the stickiness and higher price. <\/p>\n\n\n\n Small quantities of These are all moisturizing and not water soluble, so they would only work in small quantities<\/strong> in the gel formula, since xanthan gum emulsifies\/stabilizes a bit. You cannot add oils without adding additional emulsifiers which then changes the formula and ads to the price and hassle.<\/p>\n\n\n\n You might also like: my DIY deodorant without baking soda recipe<\/a><\/p>\n\n\n\nWhat not to use in a homemade hand sanitizer with essential oils<\/h2>\n\n\n\n
