How to make an ethanol foam
I’m often asked how to produce a foam with ethanol for a hand sanitiser. I know that these exist and PEG 12 dimethicone has been suggested, but seemed next to useless when I tried it. Any suggestions will be gratefully received.

Could you specify how high the ethanol content should be? do you mean just Ethanol + some Foaming agent ? or water-ethanol + foaming agent?
For pure Ethanol, I would say it is not possible in a good way. the foam will probably always be very bad if even foaming up l means you use ethanol in production to destroy Foam so the properties are rather in opposite directions :).
if you know products like that it would be interesting if you could share the INCI than it would be possible to analyze the different ingredients and see what may work.
For Water Ethanol and a Foaming agent, I would direct you to
20 - max 30 % Ethanol
1-2% PEG-7 Glyceryl Cocoate
5-8 +Cocamidopropyl Betaine
I made a Cleansing foam with similar Specifications and it was ok not great but ok.

Could you give an exact range for the ethanol content? Do you mean just some foaming agent and ethanol? or foaming agent plus ethanol and water? doodle jump

Ethanol is your antiseptic active so 60% or greater. Very Very unlikely you’ll be successful with foaming.
