Is my vegan icing shelf stable?

Is my vegan icing shelf stable? - View through blurred foliage of fresh ripe oranges and mandarins with other exotic fruits placed in red colander on wooden shelf

I make a vegan buttercream icing with Crisco, powdered sugar, vanilla extract, and soy milk/nut milk/water. If I skip the soy milk/nut milk and use water for the liquid, is the icing totally shelf stable, considering that all of the individual ingredients are shelf stable for months-years?

[EDIT] Ok, it is not shelf stable. How can I find out how long it can be left out at room temperature? I have seen people online saying anywhere from 2 days to 2 weeks.

No, it is not shelf stable, with neither water nor milk.

considering that all of the individual ingredients are shelf stable

Food safety doesn't work that way. It is not each ingredient separately that goes bad, it is the whole product, regradless of what went into it. And the mixture you describe has no good reason to be shelf stable. See also https://cooking.stackexchange.com/tags/food-safety/info.

From a food-safety perspective, you should still refrigerate anything frosted with vegan frosting. What is this? It doesn't have butter, but the dairy free milk and vegan butter should still be refrigerated if you are storing it long-term.

Can vegan buttercream be stored at room temperature?

Storing and FreezingThis will keep at room temperature for around 3 days. It will keep in the fridge for a couple of weeks though. So if you need to make it in advance of a cake, you can do so. It does firm up in the fridge, so if it gets too firm, then bring it back to room temperature on the countertop before using.
