Using Methanol in Hand Sanitizers: Is It Safe?

Introduction

The recent global pandemic has sparked a renewed interest in the production of hand sanitizers, with many individuals and organizations turning to homemade solutions. However, the use of methanol in such products has been both questioned and warned against. This article delves into the risks associated with methanol in hand sanitizers and provides recommendations for safer alternatives.

Understanding the Risks of Methanol

Methanol, also known as methylated spirit or wood alcohol, is a toxic and poisonous substance that can be easily absorbed through the skin. The Sage article dated June 23 emphasizes the dangers of using methanol for hand sanitizer, highlighting its risks to human health, including damage to the optic nerve, which is critical for vision.

While some may suggest that methanol can be used in certain quantities for hand sanitizers, it is strongly advised against due to the severe health risks involved. Any exposure to methanol, especially in concentrations found in home-made sanitizers, can be deadly.

Alternative Solutions

For those considering making their own hand sanitizer, there are safer alternatives that can be used. The simplest and one of the most effective is soapy water, which, though less potent, can effectively clean hands without causing harm.

Another commonly suggested ingredient is isopropyl alcohol, which, when properly distilled, can be a safe and effective alternative. The alcohol percentage in the final product should be kept above 62% for optimal efficacy. To convert drinking alcohol to 70% isopropyl alcohol, it would need to be at least 140 proof (according to the proof system, where 100 proof equals 50% alcohol by volume).

Proper Mixing and Storage

When creating homemade hand sanitizer, it is crucial to ensure that the final product contains between 60% to 70% alcohol by volume, with a recommendation to start higher than that. For instance, 60% alcohol equates to 120 proof, and 70% alcohol equates to 140 proof. Mixing the correct proportions and ensuring the product is well-ventilated during preparation is essential.

Precautions and Best Practices

Hand sanitizers, while useful, are not a replacement for proper handwashing with soap and water. They are most effective when used on clean, dry hands. Sanitizers should not be used if hands are visibly dirty or greasy, as these contaminants can interfere with the effectiveness of the sanitizer. When using hand sanitizer, ensure that you cover all surfaces of your hands, both the palms and the backs, and allow the solution to dry completely before wiping it off.

Conclusion

The use of methanol in hand sanitizers presents significant health risks and is not recommended. Safer alternatives, such as isopropyl alcohol or soapy water, can be effective and are much safer for public use. Always prioritize safety and follow proper guidelines when creating or using hand sanitizers at home.
