A surprisingly-nuanced and detailed piece from Gym Climber:

Alcohol percentage isn't the only issue, it appears; unbound water (not absorbed by the chalk) is also needed, and it's less effective if applied to dirty hands.

So: might be helpful, but not to be relied on as equivalent to regular hand sanitizer (which is itself less effective than hand-washing).
