Does mayonnaise have propylene glycol?

I'm curious, does mayonnaise typically contain propylene glycol as an ingredient? I've heard of it being used in some food products for its preservative properties, but I'm not sure if it's commonly found in mayonnaise. Could you clarify if this ingredient is typically included in mayonnaise or if it's more of a rare occurrence? I'm interested in understanding the makeup of this condiment and the safety of its ingredients.
