What is Polybutene?

Polybutene is a synthetic polymer used as a binder or thickener in various products. It is commonly produced by the polymerization of isobutene, resulting in a clear, sticky fluid.

In cosmetics, polybutene is primarily used for its binding and adhesion properties. It is often found in lip care products to provide gloss and a smooth application. While generally considered safe for topical use, the health evidence is limited due to the lack of ingestion studies.

When you see polybutene on a label, it's usually in small quantities and mainly for its texture-enhancing capabilities in cosmetics.

Commonly found in: Lip balms, Lip glosses, Adhesives
