Jeremiah's publishes no ingredient statements, but its own footnotes say the soy mark covers unrefined soybean oil, that all flavors contain a form of corn syrup, and that only four ices are dye free - which implies dye in the rest. Fifteen fruit ices carry no allergen marks at all.
Jeremiah's does not publish ingredient statements - the nutrition PDF is numbers and the allergen sheets are X grids. But their footnotes say more than most. The soy column is footnoted "includes Soy Lecithin and Unrefined Soybean Oil", and 46 of 102 items carry that mark, so soybean oil is in the range somewhere but the column mixes it with lecithin and you cannot tell per item which one you are getting. On additives the telling line is "Lemon, P-Nutty, Coconut, and Pina Colada Ices are Dye Free" - naming four dye-free flavors implies dye in the rest of them. They also state "All flavors contain a form of corn syrup", sulfites show up in 12 items, and the sugar-free line runs on sorbitol, sucralose and acesulfame K. If you want to order around it, 15 of the fruit ices carry no allergen marks at all, and the rule is cup not cone, no sprinkles.
