I am so over this stuff.
When it comes to safety and effectiveness, the main concern with hand sanitizers is triclosan, which is the main antibacterial ingredient in nonalcoholic hand sanitizers.
“There’s no good evidence that triclosan-containing products have a benefit,” says Allison Aiello, associate professor of epidemiology at the University of Michigan. In Europe and the United States, hospitals won’t even use them, she notes; it’s thought that they don’t reduce infections or illness.
Dr. Anna Bowen, a medical epidemiologist at The Centers for Disease Control and Prevention, says, “Triclosan-containing products don’t provide any disease protection beyond what you get from washing with soap and water.”
Research has shown that triclosan can disrupt the endocrine system, amplifying testosterone. In animal studies, it reduced muscle strength. It may also harm the immune system. Whether these findings add up to human toxicity isn’t established yet, but the FDA is currently reviewing the issue.
