According to the ISO 13485:2016, device that can be considered as medical devices is disinfectant substances. Here is the differentiation between similar products: sanitizers reduce bacteria on a surface by at least 99.9%, disinfectants kill a wider range of microorganisms (than sanitizers), and cleaners simply remove dirt, soils, and impurities from surfaces.
So, if you declare that your hand sanitizer KILLS microorganisms, that it is disinfectant and is defined as a medical device that needs to be manufactured under ISO 13485:2016. If this is not your statement, then it is most probable that your product is a cosmetic product and needs to be produced in compliance with ISO 22716:2007 Cosmetics — Good Manufacturing Practices (GMP) — Guidelines on Good Manufacturing Practices.
