Pedro's has two soybean-oil based lubes, Go! which is lighter, for dry applications, and Chainj for wet use.

I know the amount of toxics involved in bici chain lube pale in comparison to moto chains. Still, the less of that stuff I can breathe, get on my skin (yeah I wear nitrile gloves to clean and lube, but you know there's no not getting chain lube on yourself ) or leave on the road, the better. Never mind the toxic aspects of manufacturing.
