What is Polyethylene?

Polyethylene is a synthetic polymer that is commonly used in a wide variety of applications, including packaging, containers, and even in personal care products. It is made through the polymerization of ethylene, a process that creates long chains of carbon and hydrogen atoms.

In personal care products and consumer goods, polyethylene is often used for its film-forming and binding qualities. There is some controversy over its presence in consumer products due to environmental concerns, as polyethylenes are not biodegradable and contribute to microplastic pollution.

When you see polyethylene on a label, it may raise environmental concerns, especially regarding biodegradability and accumulation in the environment rather than immediate personal health risks.

Commonly found in: Deodorant, Lip Care, Diapers & Wipes, Packaging, Containers, Cosmetics
