Phenoxyethanol on an ingredient list: what WebMD and Healthline say

Reviewed October 17, 2026

The short answer

Phenoxyethanol is a preservative: it blocks the growth of microbes such as bacteria, yeast and fungi in a product. WebMD says it is widely regarded as safe at low concentrations, while Healthline calls the evidence mixed. Both describe allergic or irritant reactions that Healthline says are rare, and both raise a concern about infants.

What is it?

Both sources describe a greasy, tacky liquid that smells faintly of roses. Healthline classes it as a glycol ether, a kind of solvent. In perfumes and soaps it also acts as a stabilizer.

How it may appear on a label

Healthline lists other names: phenoxyethyl alcohol, rose ether, 2-phenoxyethanol and ethylene glycol monophenyl ether, among others. A product named Euxyl K 400 is a blend that includes it, per Healthline.

What the limit is

Healthline reports that the Cosmetic Ingredient Review panel found it safe for topical use at 1 percent or less, and reconfirmed that in 2007. The European Commission's safety committee and Japan also use a 1 percent ceiling for cosmetics, per Healthline. The same report warns that several products, each with a small amount, could add up to overexposure.

Allergy and irritation

• WebMD: an allergy can show up as hives at the application site, and in severe cases as anaphylaxis.
• Healthline: reactions include irritation, rashes, eczema and hives; anaphylaxis is very rare, and reactions are uncommon compared with how often people use it without problems.
• WebMD: people with eczema should avoid higher concentrations; if you react, stop using the product. Most skin reactions clear within days or weeks afterward.
• WebMD notes studies finding it is neither a major nor an accumulating skin irritant; Healthline notes that some argue the reactions are irritation rather than allergy.

Infants

Both sources mention a 2008 recall of a nipple cream that contained phenoxyethanol. WebMD says nursing babies who swallowed it had vomiting, diarrhea and signs of a depressed nervous system. Healthline says the FDA recalled it over effects on infants' central nervous system, and that it sees no known significant risk for healthy adults without allergies. Treat this as a reason for caution around babies and ask a pediatrician about products used on or near them. Healthline says the FDA recalled it as unsafe for breastfeeding infants over effects on the central nervous system, and advises avoiding it while pregnant or breastfeeding and for children under 3.

How to read it on a label

US cosmetic labels generally list ingredients in descending order of amount, but anything at 1% or less can appear in any order after those above 1%. Its position does not tell you the exact concentration. Judge the whole product, how it feels on your skin, and what changes when you add or drop it.

What not to conclude

This page does not say phenoxyethanol is harmful or harmless for you. The two sources differ in tone, and one says the data conflict. If a product with it irritates your skin, stop using it and ask a dermatologist.
