Can I use 90 alcohol as hand sanitizer? This is a question that many people have been asking in recent years, especially with the increased awareness of hand hygiene and the need for effective sanitizers during the COVID-19 pandemic. While 90% alcohol may seem like a powerful solution, it’s important to understand the potential risks and benefits before using it as a hand sanitizer.
Hand sanitizers are designed to kill germs on the hands, and the most effective ones contain at least 60% alcohol. The alcohol in hand sanitizers works by denaturing proteins in the cell membranes of bacteria and viruses, causing them to lose their structure and function. However, the concentration of alcohol plays a crucial role in its effectiveness and safety.
Using 90% alcohol as hand sanitizer can be effective in killing germs, but it also comes with some drawbacks. The high concentration of alcohol can be harsh on the skin, causing dryness, irritation, and even cracking. This can lead to an increased risk of infection, as the damaged skin may be more susceptible to pathogens. Additionally, the strong odor of 90% alcohol can be unpleasant and may deter some people from using it regularly.
On the other hand, using a lower concentration of alcohol, such as 70% or 75%, can still be effective in killing germs while being gentler on the skin. These concentrations are often recommended by health authorities and are widely available in commercial hand sanitizers. They provide a balance between effectiveness and skin tolerance, making them a safer and more practical choice for everyday use.
When considering whether to use 90% alcohol as hand sanitizer, it’s important to weigh the potential benefits against the risks. While it may be more potent, the harsh effects on the skin and the strong odor may make it less suitable for regular use. Instead, opting for a hand sanitizer with a lower concentration of alcohol can still provide effective protection against germs while being more gentle on the skin.
In conclusion, while it is possible to use 90% alcohol as hand sanitizer, it is not the most recommended option. A hand sanitizer with a lower concentration of alcohol, such as 70% or 75%, can still be effective in killing germs while being safer and more comfortable to use. Always prioritize skin tolerance and safety when choosing a hand sanitizer to ensure effective protection against germs.
