Coumarin is a fragrance ingredient that is known to cause allergic reactions in people and may make skin absorb things more easily. For newborns and babies (0–6 months) it is safer to avoid products that contain it.
Choose fragrance-free baby products for newborns and infants. Do not apply products that list 'coumarin' or simply 'fragrance' (which can include coumarin) to a baby’s skin. If a product containing coumarin was applied, wash the skin with plain water and mild soap, and watch the area for redness, rash or swelling. If you see any worrying signs, contact your pediatrician.
Regulatory sources note a high allergy and immune-system concern (EU Cosmetics Directive; International Fragrance Association; European Chemicals Agency). It is also restricted in some verified cosmetic programs and can act as a skin penetration enhancer (EU Cosmetics Directive), increasing absorption on thin infant skin. The FDA has historically restricted its use in food. Watch for rash, redness, hives, swelling, or breathing difficulty after skin contact — these are signs to get medical help right away. Cancer and reproductive concerns are generally listed as low by some agencies (IARC; Environment Canada), so the main concern for babies is allergic reactions and increased skin absorption.
