Mrs Darlox and I have donated many unused, unexpired amenity kits in the past. Typically local churches or homeless shelters will always take them because that kind of personal hygiene stuff, not to mention the kit itself, can be useful.
No idea if any of them have ended up being sent to disaster zones... I just figure there are a bunch of homeless people in CLE who can brush their teeth and enjoy Cowshed lip balm...
We also used to give them to friends and family who were flying long-haul coach for vacation or business, and they were well appreciated there too.
