Phenoxyethanol is a synthetic preservative used in cosmetics and personal care products to prevent the growth of bacteria, yeast, and mold, and to stabilize the products. It is an ether alcohol that is naturally found in green tea and chicory, but the version used in cosmetic products is always made in a lab. Phenoxyethanol is considered safe for use in concentrations of 1% or less, according to the Cosmetic Ingredient Review, the Food & Drug Administration, and the European Economic Community. However, it can cause skin, eye, or lung irritation in some people, and it has moderate non-reproductive organ system toxicity and occupational hazards. It is also important to note that phenoxyethanols score is higher if used in products that are inhalable (e.g., sprays, powders) because of respiratory concerns. If you are concerned about phenoxyethanol in your skincare products, you can look for products that do not contain this ingredient or consult with a dermatologist.
