I applied hand sanitizer.was not dry n accidentally my 2 yr olds lip corner touched on it n he licked it.is it dangerous(alcohol denat)?very small amt

Varies with amount: The material I use in the office is 65% ethyl alcohol combined with a number of agents that are toxic to germs and act as stabilizers for the product. Tiny amounts as you describe would not be enough to cause a problem if it is this type of sanitizer.The most toxic products out there involve methyl alcohol and those are rarely found in such commercial products..
