While there are many more chemicals we could discuss, the last one on our list today is polyethylene and PEGs. Polyethylene can be found in a myriad of products, including scrubs, body wash, makeup, and toothpaste. Do you know those small beads found in some of the best facial scrubs on the market? They contain polyethylene! These beads can be found in face scrubs, lip scrubs, and exfoliating washes. Why are they used if they are known to be harmful? They are gentler on the skin when compared to other natural exfoliators such as walnut shells.
What makes polyethylene so dangerous is the chemical called 1,4-dioxane, which has been classified in the United States as a human carcinogen. While it may not seem like much of a risk (we come into contact with carcinogens every day), the problem with 1,4-dioxane is that it is absorbed readily by the skin.
Another scary thing about this chemical is that it is often not listed on cosmetic labels! This notion is because the compound is produced after other agents have mixed within a particular cosmetic product. Switching back to polyethylene: this chemical is known as a skin irritant and is never recommended to be used on broken skin.
