Are DIY Hand Sanitizers Effective Against Coronavirus?

During the ongoing pandemic, the use of hand sanitizers has become a household necessity. However, the question of using homemade hand sanitizers as an alternative to store-bought options has raised concerns. This article delves into the effectiveness of homemade hand sanitizers against the Coronavirus (COVID-19), based on guidance from the Food and Drug Administration (FDA) and expert recommendations.

The FDA Stance on Homemade Hand Sanitizers

The FDA strongly advises against the preparation of homemade hand sanitizers, citing potential risks. Incorrect formulations can render the product ineffective, posing a threat to public health. Furthermore, there have been reports of skin burns due to improperly prepared homemade hand sanitizers. The FDA emphasizes a lack of verified safety and efficacy data for home-made products.

Ingredients and Efficacy

To understand the effectiveness of a homemade hand sanitizer, it is crucial to consider the key ingredients and concentrations. Many household items can serve as effective disinfectants, but not all are suitable for creating a product that can combat viruses like the Coronavirus.

Effective Ingredients:

Alcohol (Isopropyl alcohol): At a concentration of at least 60%, alcohol-based hand sanitizers are highly effective at reducing the number of pathogens on the skin. This aligns with the recommendations from the Centers for Disease Control and Prevention (CDC). Bleach: Sodium hypochlorite, found in household bleach, can be effective, but it must be diluted to a concentration of between 0.1% and 0.5%%. It is important to use this method after washing with soap and rinsing thoroughly to avoid skin irritation. Soap: Plain soap can be effective, especially when used correctly. The CDC and other health organizations recommend washing hands for at least 20 seconds. Chloroxylenol: Commonly found in brands like Dettol, chloroxylenol at a concentration of 4% or more is another effective ingredient. These products can be purchased online from retailers like Amazon.

Ineffective Ingredients:

Vinegar: While traditionally used for household cleaning, vinegar is not an effective antiviral agent. Baking Soda or Borax: These are not recommended for DIY hand sanitizers due to their lack of antiviral properties. Hydrogen Peroxide: At concentrations typical for DIY applications, hydrogen peroxide is not effective. Higher concentrations can be painful for the user. Pine, lemon, or orange oils: While beta-pinene and limonene found in these oils have shown potential antiviral activity in laboratory settings, their efficacy in DIY formulations is uncertain.

Expert Recommendations

It is important to follow established guidelines for hand sanitizers. The CDC, Environmental Protection Agency (EPA), and consumer reports provide comprehensive lists of effective ingredients. Additionally, reputable websites contain detailed information on creating and using hand sanitizers. A simple internet search can provide valid information and guidance.

Conclusion

The effectiveness of DIY hand sanitizers against the Coronavirus depends largely on the ingredients and concentrations used. While some ingredients can be effective, the risks associated with improper preparation and usage should not be overlooked. The FDA's guidance highlights the importance of using products that have been rigorously tested and certified. Simple soap and water, soap alone, or commercially available sanitizers are still recommended as the best methods to protect against the virus.
