Making hand sanitizer at home – Quick & Tested Recipes

About hand sanitizer and How to Make Hand Sanitizer at home?

Hand sanitizer (also known as hand antiseptic, hand disinfectant, hand rub, or handrub) is a liquid, gel or foam generally used to kill many viruses/bacteria/microorganisms on the hands. In most settings, hand washing with soap and water is generally preferred. Hand sanitizer is less effective at killing certain kinds of germs, such as norovirus and Clostridium difficile, and unlike hand washing, it cannot physically remove harmful chemicals. People may incorrectly wipe off hand sanitizer before it has dried, and some are less effective because their alcohol concentrations are too low. (How to Make Hand Sanitizer)

Alcohol-based hand sanitizer that is at least 60% (v/v) alcohol in water (specifically, ethanol or isopropyl alcohol/isopropanol (rubbing alcohol)) is recommended by the United States Centers for Disease Control and Prevention (CDC), but only if soap and water are not available. The CDC recommends the following steps when using an alcohol-based hand sanitizer:

1. Apply product to the palm of one hand.
2. Rub hands together.
3. Rub the product over all surfaces of hands and fingers until hands are dry.
4. Do not go near flame or gas burner or any burning object during application of hand sanitizer. (How to Make Hand Sanitizer)

In most healthcare settings, alcohol-based hand sanitizers are preferable to hand washing with soap and water, because it may be better tolerated and is more effective at reducing bacteria. Hand washing with soap and water, however, should be carried out if contamination can be seen, or following the use of the toilet. The general use of non-alcohol-based hand sanitizers is not recommended. (How to Make Hand Sanitizer)

Alcohol-based versions typically contain some combination of isopropyl alcohol, ethanol (ethyl alcohol), or n-propanol, with versions containing 60% to 95% alcohol the most effective. Care should be taken as they are flammable. Alcohol-based hand sanitizer works against a wide variety of microorganisms but not spores. Compounds such as glycerol may be added to prevent drying of the skin. Some versions contain fragrances; however, these are discouraged due to the risk of allergic reactions. Non-alcohol based versions typically contain benzalkonium chloride or triclosan; but are less effective than alcohol-based ones.

General public

Alcohol-based hand sanitizers may not be effective if the hands are greasy or visibly soiled. In hospitals, the hands of healthcare workers are often contaminated with pathogens, but rarely soiled or greasy. In community settings, on the other hand, grease and soiling is common from activities such as handling food, playing sports, gardening, and being active outdoors. Similarly, contaminants like heavy metals and pesticides (generally found outdoors ) cannot be removed by hand sanitizers. Hand sanitizers might also be swallowed by children, especially if brightly colored. (How to Make Hand Sanitizer)

Some commercially available hand sanitizers (and online recipes for homemade rubs) have alcohol concentrations that are too low. This makes them less effective at killing germs. Poorer people in developed countries and people in developing countries may find it harder to get a hand sanitizer with an effective alcohol concentration. Fraudulent labelling of alcohol concentrations has been a problem in Guyana. (How to Make Hand Sanitizer)

Alcohol has been used as an antiseptic at least as early as 1363 with evidence to support its use becoming available in the late 1800s. Alcohol-based hand sanitizer has been commonly used in Europe since at least the 1980s. The alcohol-based version is on the World Health Organization’s List of Essential Medicines, the safest and most effective medicines needed in a health system.

Schools

The current evidence for the effectiveness of school hand hygiene interventions is of poor quality.

In a 2020 Cochrane review comparing rinse-free hand washing to conventional soap and water techniques and the subsequent impact on school absenteeism found a small but beneficial effect on rinse-free hand washing on illness related absenteeism. (How to Make Hand Sanitizer)

Health care

Hand sanitizers were first introduced in 1966 in medical settings such as hospitals and healthcare facilities. The product was popularized in the early 1990s.

Alcohol-based hand sanitizer is more convenient compared to hand washing with soap and water in most situations in the healthcare setting. Among healthcare workers, it is generally more effective for hand antisepsis, and better tolerated than soap and water. Hand washing should still be carried out if contamination can be seen or following the use of the toilet. (How to Make Hand Sanitizer)

Hand sanitizer that contains at least 60% alcohol or contains a “persistent antiseptic” should be used. Alcohol rubs kill many different kinds of bacteria, including antibiotic resistant bacteria and TB bacteria. They also kill many kinds of viruses, including the flu virus, the common cold virus, coronaviruses, and HIV.

90% alcohol rubs are more effective against viruses than most other forms of hand washing. Isopropyl alcohol will kill 99.99% or more of all non-spore forming bacteria in less than 30 seconds, both in the laboratory and on human skin. (How to Make Hand Sanitizer)

In too low quantities (0.3 ml) or concentrations (below 60%), the alcohol in hand sanitizers may not have the 10–15 seconds exposure time required to denature proteins and lyse cells. In environments with high lipids or protein waste (such as food processing), the use of alcohol hand rubs alone may not be sufficient to ensure proper hand hygiene.

For health care settings, like hospitals and clinics, optimum alcohol concentration to kill bacteria is 70% to 95%. Products with alcohol concentrations as low as 40% are available in American stores, according to researchers at East Tennessee State University. (How to Make Hand Sanitizer)

Alcohol rub sanitizers kill most bacteria, and fungi, and stop some viruses. Alcohol rub sanitizers containing at least 70% alcohol (mainly ethyl alcohol) kill 99.9% of the bacteria on hands 30 seconds after application and 99.99% to 99.999% in one minute.

For health care, optimal disinfection requires attention to all exposed surfaces such as around the fingernails, between the fingers, on the back of the thumb, and around the wrist. Hand alcohol should be thoroughly rubbed into the hands and on the lower forearm for a duration of at least 30 seconds and then allowed to air dry. (How to Make Hand Sanitizer)

Use of alcohol-based hand gels dries skin less, leaving more moisture in the epidermis, than hand washing with antiseptic/antimicrobial soap and water. (How to Make Hand Sanitizer)

Hand sanitizers containing a minimum of 60 to 95% alcohol are efficient germ killers. Alcohol rub sanitizers kill bacteria, multi-drug resistant bacteria (MRSA and VRE), tuberculosis, and some viruses (including HIV, herpes, RSV, rhinovirus, vaccinia, influenza, and hepatitis) and fungi. Alcohol rub sanitizers containing 70% alcohol kill 99.97% (3.5 log reduction, similar to 35 decibel reduction) of the bacteria on hands 30 seconds after application and 99.99% to 99.999% (4 to 5 log reduction) of the bacteria on hands 1 minute after application. (How to Make Hand Sanitizer)

Drawbacks

There are certain situations during which hand washing with soap and water are preferred over hand sanitizer, these include: eliminating bacterial spores of Clostridioides difficile, parasites such as Cryptosporidium, and certain viruses like norovirus depending on the concentration of alcohol in the sanitizer (95% alcohol was seen to be most effective in eliminating most viruses). In addition, if hands are contaminated with fluids or other visible contaminates, hand washing is preferred as well as after using the toilet and if discomfort develops from the residue of alcohol sanitizer use. Furthermore, CDC states hand sanitizers are not effective in removing chemicals such as pesticides.

Safety

Fire

Alcohol gel can catch fire, producing a translucent blue flame. This is due to the flammable alcohol in the gel. Some hand sanitizer gels may not produce this effect due to a high concentration of water or moisturizing agents. There have been some rare instances where alcohol has been implicated in starting fires in the operating room, including a case where alcohol used as an antiseptic pooled under the surgical drapes in an operating room and caused a fire when a cautery instrument was used. Alcohol gel was not implicated. (How to Make Hand Sanitizer)

To minimize the risk of fire, alcohol rub users are instructed to rub their hands until dry, which indicates that the flammable alcohol has evaporated. Igniting alcohol hand rub while using it is rare, but the need for this is underlined by one case of a health care worker using hand rub, removing a polyester isolation gown, and then touching a metal door while her hands were still wet; static electricity produced an audible spark and ignited the hand gel. Fire departments suggest refills for the alcohol-based hand sanitizers can be stored with cleaning supplies away from heat sources or open flames.

Skin

Research shows that alcohol hand sanitizers pose any risk by eliminating beneficial microorganisms that are naturally present on the skin. The body quickly replenishes the beneficial microbes on the hands, often moving them in from just up the arms where there are fewer harmful microorganisms.

However, alcohol may strip the skin of the outer layer of oil, which may have negative effects on barrier function of the skin. A study also shows that disinfecting hands with an antimicrobial detergent results in a greater barrier disruption of skin compared to alcohol solutions, suggesting an increased loss of skin lipids. (How to Make Hand Sanitizer)

Frequent use of alcohol-based hand sanitizers can cause dry skin unless emollients and/or skin moisturizers are added to the formula. The drying effect of alcohol can be reduced or eliminated by adding glycerin and/or other emollients to the formula. In clinical trials, alcohol-based hand sanitizers containing emollients caused substantially less skin irritation and dryness than soaps or antimicrobial detergents. Allergic contact dermatitis, contact urticaria syndrome or hypersensitivity to alcohol or additives present in alcohol hand rubs rarely occur. The lower tendency to induce irritant contact dermatitis became an attraction as compared to soap and water hand washing. (How to Make Hand Sanitizer)

Ingestion

In the United States, the U.S. Food and Drug Administration (FDA) controls antimicrobial handsoaps and sanitizers as over-the-counter drugs (OTC) because they are intended for topical anti-microbial use to prevent disease in humans. (How to Make Hand Sanitizer)

The FDA requires strict labeling which informs consumers on proper use of this OTC drug and dangers to avoid, including warning adults not to ingest, not to use in the eyes, to keep out of the reach of children, and to allow use by children only under adult supervision. According to the American Association of Poison Control Centers, there were nearly 12,000 cases of hand sanitizer ingestion in 2006. 

If ingested, alcohol-based hand sanitizers can cause alcohol poisoning in small children. However, the U.S. Centers for Disease Control recommends using hand sanitizer with children to promote good hygiene, under supervision, and furthermore recommends parents pack hand sanitizer for their children when traveling, to avoid their contracting disease from dirty hands. (How to Make Hand Sanitizer)

People suffering from alcoholism may attempt to consume hand sanitizer in desperation when traditional alcoholic beverages are unavailable, or personal access to them is restricted by force or law. There have been reported incidents of people drinking the gel in prisons and hospitals to become intoxicated. As a result, access to sanitizing liquids and gels is controlled and restricted in some facilities. 

For example, over a period of several weeks during the COVID-19 pandemic in New Mexico, seven people in that U.S. state who were alcoholic were severely injured by drinking sanitizer: three died, three were in critical condition, and one was left permanently blind. (How to Make Hand Sanitizer)

In 2021, a dozen children were hospitalized in the state of Maharashtra, India, after they were mistakenly orally administered hand sanitizer instead of a polio vaccine. (How to Make Hand Sanitizer)

• What if you can always stay germ-free and virus-free?
• You can’t wash your hands everywhere, such as when traveling or serving in an isolated worksite, so what can you do to stay germ-free?
• Yes, you turn towards hand sanitizers because they get the job done anywhere. But what if they run short in case of a pandemic eruption?
• You do it yourself at home!
• This blog will tell you how. He will explain everything about homemade hand sanitizer, backed by scientific evidence, from recipes for homemade hand sanitizer to proportions and care instructions for different amounts.

How do hand sanitizers work?

According to Insider, hand sanitizer must contain at least 60% alcohol to be effective at killing germs and viruses. But normally hand sanitizers use 90-99% alcohol. Alcohol works by destroying the cell walls of microbes, breaking them down and destabilizing their metabolism. (How to Make Hand Sanitizer)

Hand sanitizer ingredients:

The main ingredient is alcohol, although some use propanol and isopropanol. Other components include:

• Aloe vera or glycerol: for moisturizing properties
• Essential oils such as tea tree oil or lavender oil: to give the liquid a pleasant scent
• Color pigments: for color
• Hydrogen peroxide: used to kill contaminating bacteria that may enter the liquid during preparation

Does hand sanitizer work for viruses?

• Yes it is. There are many studies confirming the effectiveness of hand sanitizers in reducing bacteria such as MRSA, E.coli and salmonella.
• You’d see many bottles of hand sanitizer labeled “Kill 99% germs.” While true for most pathogens, it may not be entirely true for some microbes such as Norovirus and Cryptosporidium. Both of these parasites can cause diarrhea.

How to make homemade hand sanitizer?

You should always use commercial hand sanitizers; But in emergencies, home preparation becomes inevitable when you suddenly run out of market or are not allowed to leave your home.

It can be made in smaller and larger quantities. We will share each recipe with you.

Hand sanitizer recipe (small volume)

There is a simple ratio to keep in mind as you prepare.

Use 3 parts alcohol (90-99%) and 1 part aloe vera.

Gel type:

1. Measure out ¾ glass of alcohol and transfer it to a bowl.
2. Measure out ¼ cup of aloe vera gel from the plant and pour it into the bowl.
3. Add 5-10 drops of essential oil you have with you.
4. Mix all the ingredients with the help of a spoon and leave the mixture for 20-30 minutes.
5. Transfer the prepared hand sanitizer to a soap bottle with a funnel. (How to Make Hand Sanitizer)

Spray type:

Aloe vera can make your hands sticky, so if you want to make a spray-type version of hand sanitizer, here’s the recipe.

1. Mix three parts alcohol with 1 part witch hazel.
2. Pour the desired drop of essential oil and colored pigment.
3. Mix all the ingredients together and let it sit for a while before transferring it to a spray bottle. (How to Make Hand Sanitizer)

Hand sanitizer recipe (large volume)

Check the WHO approved recipe for making larger volumes of hand sanitizer. For this you need the following components:

• Hydrogen peroxide (3%)
• Glycerol
• Alcohol
• Boiled (then cooled) water (How to Make Hand Sanitizer)

Care instructions while making hand sanitizer at home

You are definitely making a disinfectant, but it can become contaminated if not prepared carefully.

1. Use the sterilized apparatus (mixer, bowl, etc.).
2. WHO recommends that the solution be left for 72 hours before use when preparing large quantities.
3. Do not sneeze or cough in the solution; otherwise all disinfectant will be contaminated. Use gloves and a mask during preparation, especially when preparing large quantities.
4. Use only recommended rates. (How to Make Hand Sanitizer)

Homemade hand sanitizer vs. Handwashing

Clear as glass: Hand washing is a better way to avoid viruses and germs. Homemade hand sanitizer should only be used if soap and water are not available.

However, it is a sure means of protection against diseases as well as boosting your immune system.

You should use hand sanitizer immediately if:

1. After leaving the washroom
2. After getting off public transport (you may have grabbed the seat and poles of the bus/train)
3. After sneezing and blowing your nose
4. After playing at home or on the ground

Conclusion

Using hand sanitizer can protect you from harmful viruses and bacteria, but you can only make them at home if they are extinct on the market and you don’t have access to regular hand washing. We hope you never encounter such situations. (How to Make Hand Sanitizer)
