Isoeugenol is a fragrance chemical that can cause skin allergies. For toddlers (1–2 years), it poses a moderate risk because their skin is still sensitive and they can develop rashes or allergic reactions.
Avoid putting products with isoeugenol on a toddler’s skin whenever possible. Choose fragrance-free baby products. If a product lists isoeugenol by name or lists “fragrance” without details, don’t use it on children under 2. If you must try a product, test a very small area on the child’s arm and wait 24–48 hours for any reaction, but the safest choice is to avoid it entirely for toddlers.
Do not use products containing isoeugenol on broken or irritated skin. Stop use immediately and contact your child’s doctor if you see redness, swelling, hives, itching, or a spreading rash after use. Regulatory sources (EU Cosmetics Directive and fragrance industry guidance) list isoeugenol as an allergen and restrict or limit its use in cosmetics and require labeling — that is the reason to avoid it for young children. Other assessments note low concern for cancer or developmental harm, but those are not the main issue here.
