Thanks BB!

Oil based.
It's called "food safe" to the extent that other finishes like poly are called food safe after they are dried.
I looked into it a bit and now it is just labeled "wood bowl finish"

From the Mfg:
General Finishes Wood Bowl Finish (formerly Salad Bowl Finish) is an oil-and-urethane topcoat designed to safely coat decorative wooden bowls, cups, and spoons. It builds a durable, amber-toned, gloss film that is food-safe and non-toxic once fully cured

I like how they added "decorative"
