ℹ️General Overview

For newborns and infants (0-6 months), this ingredient is best avoided. It is a fragrance chemical known to cause skin allergies in some people, and babies’ skin is more likely to react.

✅What to Do

Choose fragrance-free baby products (look for ‘fragrance-free’ or ‘unscented’ on the label). Do not use adult perfumed lotions, colognes, or scented wipes on your baby. If a product with this ingredient was used, gently wash the area with plain water and a mild, fragrance-free cleanser and stop using the product.

⚠️Warnings

Watch for redness, rash, itching, bumps, swelling, or increased crying near where a product was applied — these are signs of an allergic reaction. This ingredient is listed as a known or possible skin allergen by regulators (for example: EU Cosmetics Directive, IFRA and the U.S. EPA), which is why extra caution is recommended for infants.

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.
