ℹ️General Overview

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.

What to Do

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.

⚠️Warnings

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.

Safety Risk Labels

This ingredient has the following documented risks:

Irritant: This chemical is listed as a known human allergen and as causing dermal reactions by multiple regulatory bodies (the EU cosmetics listing and fragrance industry guidance, with strong evidence noted by the U.S. EPA). That means it can cause skin redness, itching, or rash after contact.
Immune system: Several authorities identify this ingredient as an allergen or possible immune-system toxicant (noted by the EU cosmetics rules, the EPA, and related fragrance regulators), so it can trigger immune responses rather than being inert on the skin.
Eczema: Because this ingredient is flagged for causing skin allergy and limited dermal toxicity by agencies such as ECHA and the EU cosmetics framework, it can worsen or trigger eczema and similar skin conditions in sensitive children.
Environmental: An environmental agency has identified this substance as a suspected environmental toxin, meaning it may harm wildlife or the environment if released, so there is some ecological concern with its use.
