Hidrofugal Classic does not contain alcohol (but aluminum). For me, the Spray was a discovery that I'm going to buy now probably regularly, which is attractive especially in 2 of the main points: a) sweat reduction and b) discreet neutral scent. Neutral triffts, but it is not so that no odor is present; me it slightly reminiscent of lilacs.
Although no better / more practical than a scooter, the spray can be well applied to bare skin (best: as long as no undershirt is slipped over). I use an empty roll on to distribute the spray under the armpits. A few seconds should be maintained until the skin has included the spray and dried. Am satisfied.
