Phenoxyethanol

Low ConcernpreservativeEWG: 4

The most widely used synthetic preservative in modern cosmetics — a paraben replacement.

How it works

Phenoxyethanol is an aromatic ether alcohol that disrupts bacterial cell membranes and inhibits fungal growth. It replaced parabens in many formulations in the 2000s after paraben concern grew. It is effective across a broad pH range and is stable, but concerns have emerged about its safety in products used around the mouth or applied to broken skin.
