Dunkin Donuts frozen coffee

Would a frozen coffee from a non-certified Dunkin Donuts store be acceptable for year-round when traveling?
For example, with a butter pecan swirl:

Water; Light Cream: Milk, Cream, Disodium Phosphate (Stabilizer), Sodium Citrate (Stabilizer); Liquid Cane Sugar: Pure Cane Sugar, Water, Potassium Sorbate (Preservative); Coffee Swirl Syrup: Water, Sugar, Coffee, Phosphoric Acid, Natural Flavor, Dipotassium Phosphate, Salt, Sodium Benzoate and Potassium Sorbate (Preservatives), Xanthan Gum; Butter Pecan Flavored Swirl Syrup: Skim Milk, Sugar, High Fructose Corn Syrup, Water, Brown Sugar (Sugar, Molasses), Natural and Artificial Flavors, Caramel Color, Salt, Disodium Phosphate, Potassium Sorbate (Preservative); Whipped Light Cream: Cream, Skim Milk, Corn Syrup, High Fructose Corn Syrup, Mono and Diglycerides, Carrageenan, Dextrose, Natural and Artificial Flavor; Caramel Flavored Swirl Syrup: Sweetened Condensed Nonfat Milk, High Fructose Corn Syrup, Sugar, Water, Brown Sugar, Caramel Color, Potassium Sorbate (Preservative), Natural Flavor, Salt.

Thank you very much for your help.
