                                According to manufacturers like Dairy Queen, specific Misty® Slush flavors do contain propylene glycol as a listed ingredient. This food-grade compound is used to achieve the drink's signature, semi-frozen texture and is distinct from the toxic chemical found in automotive antifreeze.
