There is no substantial scientific evidence to suggest that hand sanitizer directly causes cancer. The primary active ingredients in most hand sanitizers are alcohol-based substances like ethanol and isopropanol, which have been extensively studied for their safety and efficacy. However, concerns have been raised about other ingredients, such as triclosan, which has been linked to various health issues, including potential carcinogenic effects. It is important to note that many hand sanitizers no longer contain triclosan due to these concerns.
