ℹ️General Overview

For toddlers and preschoolers (ages 2–5), this ingredient is usually low risk overall but is a known fragrance allergen. That means some children can get a rash or irritation from products that smell of it.

✅What to Do

Prefer fragrance-free products for young children. If you must use a scented product, choose one made for kids, use a small amount on a small area first (patch test) and wait 24–48 hours to watch for redness, itching, or bumps. Keep it away from the face and broken skin. If your child has a history of sensitive skin or eczema, avoid this ingredient entirely.

⚠️Warnings

Watch for signs of contact allergy: redness, itching, swelling, bumps, or blisters where the product was applied. Regulatory guidance and fragrance industry standards (for example: the EU Cosmetics Directive and IFRA) list this as an allergen or restrict its use — that is why it can cause reactions. Stop use and see a doctor if a strong reaction occurs.

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.
