Benzyl Alcohol

Benzyl Alcohol

Doubles as a scent and a preservative. It’s on the EU’s list of fragrance allergens, so fragrance-sensitive skin can react to it.

What it does

Benzyl alcohol works both as a fragrance chemical and as a preservative in cosmetics; EU rules allow up to 1% as a preservative. It is on the EU's fragrance-allergen list and an established contact allergen. Because it can be there as a preservative, it can turn up in products labeled fragrance-free.

The EU’s ingredient database lists it as a preservative (holds back germs in the product), a fragrance (adds scent) and a solvent (dissolves other ingredients).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗

The evidence, graded

moderateFragrance, essential oils, denatured alcohol and certain preservatives (methylisothiazolinone, the formaldehyde-releasers) are the usual suspects on sensitive skin. In the patch-test data read here — patients whose dermatitis was linked to a cleanser — the preservative quaternium-15 topped the list at 11.2% and fragrance mix I came fifth at 7.7%. Test a new product on a small patch of skin before you use it on your face.Warshaw 2018 · Dermatitis ↗
expert consensusBenzyl alcohol and benzyl salicylate are on the EU’s 26-name fragrance label list, and both are known skin allergens. Benzyl alcohol is often in a formula as a preservative rather than for scent, so seeing it does not by itself mean a product is fragranced. It can still reach someone allergic to it in a product labeled fragrance-free. Benzyl salicylate is on the list as a fragrance chemical.SCCS 2012 · European Commission SCCS ↗
