Couldn't find any Dow 111 OR any lithium grease :-)),
but what I did find is called
"Sanitary PETROL-GEL Lubricant".
"Technical White Grease....valves - pistons -o-rings"
"NSF"
"packaged by McGlaughlin Oil Co."
Sound okay? It was in the drawer of espresso machine "lubes and sealants", so I'm guessing this is what I got it for however many years ago I got it...
