Phenoxyethanol

Q: Can Phenoxyethanol cause skin irritation?

Phenoxyethanol has a low irritation risk. Generally well tolerated at cosmetic concentrations of up to 1%. Rare cases of allergic contact dermatitis and, in isolated cases, anaphylaxis have been reported. At 2%, it was a mild irritant in animal studies but not a sensitiser. Listed under EU CosIng Annex V/29 as an approved preservative with a maximum concentration of 1% in all cosmetic products. Not restricted under Annex II (banned) or Annex III (restricted actives).

Q: Is Phenoxyethanol safe to use during pregnancy?

Phenoxyethanol is rated "caution" for pregnancy use. Dermal animal studies found no teratogenicity, embryotoxicity, or fetotoxicity at maternally-tolerated doses (Cosmetic Ingredient Review). However, high-dose dietary studies in mice showed dose-dependent effects on offspring at elevated concentrations. Most experts recommend avoiding products containing phenoxyethanol on large body surface areas during pregnancy as a precaution, and avoiding use in the nappy/diaper area for children under 3 years old (French ANSM guidance, 2019). Topical use in normal cosmetic concentrations is generally considered low risk. Consult a healthcare provider if in doubt.

Q: Does Phenoxyethanol increase sun sensitivity?

Phenoxyethanol has a no sun sensitivity risk. Phenoxyethanol does not increase photosensitivity. No sun protection precautions are required based on its presence in a formulation.

Q: What skin types is Phenoxyethanol suitable for?

Phenoxyethanol is suitable for all skin types, oily, dry, combination, sensitive (with patch test recommended for allergy-prone individuals).

INCI: Phenoxyethanol

Phenoxyethanol is a widely-used synthetic preservative and solvent that protects cosmetic formulations from microbial contamination by bacteria, yeast, and mould. It is an aromatic ether that occurs naturally in small amounts in green tea, though cosmetic-grade phenoxyethanol is synthetically produced. It is thermally stable up to 85°C and effective across a broad pH range of 3–10, making it compatible with most formulation types.
