Phenoxyethanol

Phenoxyethanol is a glycol ether preservative that has become one of the most widely used alternatives to parabens in cosmetic formulations. It provides broad-spectrum antimicrobial protection against bacteria, yeast, and mold at typical use levels of 0.5-1.0%, while remaining stable across a wide pH range and compatible with most cosmetic ingredients. Formulators favor it for its efficacy, lack of formaldehyde release, and relatively mild sensory profile, though it must be combined with other preservatives for optimal gram-negative bacterial control.
