For 1–2 year old toddlers: this scent ingredient can cause skin allergies. It isn’t linked to cancer or developmental harm in the available data, but it often causes redness, itching, or rashes in sensitive children.
Prefer fragrance-free products for toddlers. If you must use a product that may contain fragrances, do a small patch test on a clean area (inner forearm or thigh) and wait 24–48 hours for any reaction before regular use. Avoid putting fragranced products on the face, around the mouth or on broken or inflamed skin. Read labels for the name “alpha‑isomethyl ionone” or generic “fragrance” and choose products that list individual allergens when possible. If your child has eczema, sensitive skin, or a history of allergies, skip fragranced products altogether and talk with your pediatrician.
Watch for any redness, swelling, itching, blistering or rash after use and stop the product right away. This ingredient is listed as a known or possible allergen by regulatory and industry sources (for example, the EU Cosmetics Directive and the fragrance industry group IFRA), and some agencies (EPA, ECHA) report evidence of skin sensitization. Because of these reports and labeling rules, avoid routine use on toddler skin and be extra cautious if your child already has sensitive skin or eczema.
