Polyethylene Glycol vs. Cetearyl Olivate
The chemical ingredient: Polyethylene glycol
Explanation: "Polyethylene glycol (or PEG) is actually a class of ingredients that can emulsify a formula and enhance the penetration of other ingredients into the skin. They can often be contaminated with impurities like ethylene oxide (used in mustard gas manufacturing) and heavy metals."
The natural option: Cetearyl olivate
Why it works: "Fatty acids from olives give this emulsifier deeply hydrating properties, helping to smooth skin. It also gives the products it's in a silky texture."
