If one takes the time to search on Health Canada website, they state that washing hands with soap and water for at least 20 seconds is still the most effective way to limit the spread of COVID-19. But if that method is unavailable, the use of hand sanitizers is recommended.
I suspect the public is unaware that prior to the pandemic, hand sanitizers contained food-grade ethanol. Since then, the federal government has allowed manufacturers to incorporate technical grade 70 per cent ethanol, which is intended to be used as a surface disinfectant (not for hands).
The difference is that technical grade 70 per cent ethanol contains impurities, one of which is acetaldehyde. It’s toxic and poses a health risk to humans which if the liver doesn’t break down and dispose of it. The developing fetus and infant’s liver lack the enzyme that breaks down acetaldehyde. It’s uncertain when the infant produces this enzyme. That’s why all baby products are required to be alcohol-free.
