Propylparaben is a preservative that is used in some processed foods to extend their shelf life by preventing the growth of mold and bacteria. It is also used in some personal care products and cosmetics. According to the Environmental Working Group (EWG), propylparaben is found in 49 processed foods, including Sara Lee cinnamon rolls, Weight Watchers cakes, and La Banderita Corn Tortillas. Some of the typical food products that contain parabens for preservation include beer, sauces, desserts, soft drinks, jams, pickles, frozen dairy products, processed vegetables, and flavoring syrups. Here is a list of some of the foods that contain propylparaben:

• Amport Foods Chocolate & Nut Trail Mix
• Archer Farms Gourmet Dessert Cookies
• Arizona Snack Company Canyon Runner II Trail
• Arizona Snack Company Sweet Energy Trail
• Cafe Valley Apple Spice Mini Muffins
• Cafe Valley Banana Nut Mini Muffins
• Cafe Valley Blueberry Mini Muffins
• Cafe Valley Cake Pumpkin Cream Cheese
• Cafe Valley Chocolate Chips Mini Muffins
• Cafe Valley Corn Mini Muffins
• Sara Lee cinnamon rolls
• Weight Watchers cakes
• La Banderita Corn Tortillas

It is important to note that while the FDA has classified methyl and propylparaben as "Generally Regarded As Safe" for use in preserving food, there is evidence that propylparaben is an endocrine disruptor and can affect reproductive health.
