Phenethyl Alcohol

INCI: Phenethyl Alcohol

Phenethyl alcohol (2-phenylethanol) is an aromatic alcohol that occurs naturally in essential oils such as rose, neroli, and geranium. In cosmetics it serves a dual role: it masks the unpleasant odour of other ingredients with its pleasant rose-like scent, and it provides antimicrobial activity that boosts the efficacy of traditional preservative systems.

Is Phenethyl Alcohol safe? Key considerations

Can Phenethyl Alcohol cause irritation?

Low Risk

EWG hazard score of 1 (lowest risk). Generally well tolerated at typical cosmetic concentrations (under 1%). At higher concentrations it can cause mild skin and eye irritation. Not restricted under EU CosIng Annex II or III for cosmetic use, though it is regulated as a fragrance allergen component in some jurisdictions.

Does Phenethyl Alcohol increase sun sensitivity?

No Risk

Phenethyl alcohol does not increase photosensitivity. No additional sun protection measures are required when using products containing this ingredient.

Is Phenethyl Alcohol safe during pregnancy?

Caution

MANUAL REVIEW: Limited specific pregnancy safety data available. CIR rated it as B (safe with qualifications). As a fragrance/preservative ingredient used at low concentrations it is generally considered low risk, but no dedicated reproductive toxicity studies specific to cosmetic use were identified across sources. Consult a healthcare provider if concerned.
