Is touching .5 Molar sodium hydroxide dangerous

It was in chem class for a lab and it was literally only a drop. I put on hand sanitized afterwards and washed my hands.

no, there is no danger.
next time, use water first. then use the hand sanitizer. the hand sanitizer is alcohol. you don't know if the alcohol will react with the particular chemical that spilled on your hand.
0.5M NaOH will feel slimy but that's it. 1M or higher, if left on your skin, will start to tingle and, with higher concentrations, burn.

in laboratory u have the concentration of much lower than expected in real...so it wont harm u...dn worry..but it could be dangerouif the volume is large
