The TSA announced that up to 12 ounces of hand sanitizer can go through security checkpoints now. The larger bottles will be screened separately so allow extra time through security.
.@TSA now allowing passengers to bring liquid hand sanitizer up to 12 oz in carry-on bags until further notice. Expect these containers larger than the standard of 3.4 oz of liquids will need to be screened separately, which will add some time to checkpoint screening.

The ban on liquids and gels has been in place since 2006 after a potential terrorist plot was uncovered on a flight heading to the United States.
If this isn’t a security threat now, then it likely has never been a security threat.
