PEG 300 is a polyethylene glycol compound used in food and cosmetics and is currently approved by the FDA for use in the United States. PEG 300 is used as a thickener, emulsifier, and stabilizer in foods. It is also approved for use in cosmetics as an emulsifier, lubricant, and moisturizer.

PEG 300 in Food

In addition to thickening, PEG 300 also helps reduce the freezing point of water, which is why it's often used as an ingredient in frozen foods like sorbet and is also found in other non-frozen foods, including:
  • Seasoning Blends
  • Salad Dressings
  • Flavored Teas
  • Food Coloring
  • Cake Frosting
  • Marshmallows
  • Cheese
You can find PEG 300 in many other types of food commonly found in your pantry or grocery store shelf.

PEG in Cosmetics

PEG is used in cosmetics as a solvent, emulsifier, thickener, and humectant. In other words, it helps keep oil and water from separating; and helps hold together everything from creams to toothpaste. Everyday cosmetics where you will find PEG 300 include:
  • Blush
  • Primer
  • Eye Makeup
  • Brow Liner
  • Lip Balm
PEG 300 is used in cosmetics to help protect the skin from environmental damage caused by ultraviolet (UV) rays from the sun. PEG works best at this when combined with other ingredients that reduce inflammation and irritation caused by UV exposure.
