Ingredients with a documented concern, from official datasets and our reviewed database.

Severity 7/10
Sensitive skin: High cautionPregnancy: Best avoidedBabies & kids: Best avoidedEczema-prone: High caution
  • Hormone disruption:Classified as toxic to reproduction (CMR 1B); banned in the EU since March 2022.
  • Allergy risk:Well-documented fragrance sensitizer.
EU CLP Repr. 1B ↗EU CosIng Annex II (prohibited in cosmetics) ↗

The lily-of-the-valley scent 'Lilial', banned in EU cosmetics in 2022 after being classified as presumed toxic to human reproduction. Still legal in some other markets — check older or imported products.

Linalool

fragrance

Severity 5/10
Sensitive skin: Use with cautionEczema-prone: High caution
  • Allergy risk:EU-declarable allergen; oxidized linalool is a common patch-test positive.
EU CLP Skin Sens. 1B ↗EU CosIng Annex III (declarable / restricted) ↗

A floral scent molecule found in lavender and many essential oils. It oxidizes on air exposure into strongly sensitizing compounds, which is why it must be declared on EU labels.

Severity 4/10Editorial
Sensitive skin: Use with cautionEczema-prone: Use with caution
  • Allergy risk:Named Allergen of the Year 2004; impurities (amidoamine) drive most reactions.

A mild coconut-derived surfactant in countless 'gentle' cleansers. Most allergy is caused by manufacturing impurities, so quality varies by brand.

Coumarin

fragrance

Severity 5/10
Sensitive skin: Use with cautionEczema-prone: Use with caution
  • Allergy risk:EU-declarable allergen found in tonka bean and many perfumes.
EU CosIng Annex III (declarable / restricted) ↗

A sweet hay-scented molecule requiring EU allergen declaration; a regular positive in fragrance patch-test series.

Pore-clogging potential (1)

Ingredients rated likely to clog pores — relevant if your skin is acne-prone. This is a separate indicator and is not part of the safety score.

Indicative Fulton-scale ratings from published dermatology references — not a regulator classification; individual reactions vary.

No concerns found (8)

Ingredients that are unflagged in our reviewed database, reviewed safe by the CIR panel, or on an EU permitted list.

Recognized ingredients (2)

Catalogued in official cosmetic-ingredient inventories (EU CosIng and others) with no safety flag on record. Being recognized isn't a safety guarantee — it means the ingredient is on record but no authority has published a concern.

  • BUTYLOCTANOL· humectant, solvent
  • LAURYL METHYL GLUCETH-10 HYDROXYPROPYLDIMONIUM CHLORIDE· antistatic, hair conditioning

Not enough data (2)

Not found in any dataset we hold (often trade-name blends or very niche ingredients), so we can't assess them — this is not a safety judgment either way.

  • FRAGRANCE (PARFUM) SODIUM BENZOATE
  • DILINOLEC ACID

This report is informational, not medical advice. Assessments summarize published findings (EU CosIng, IARC, ECHA, CIR, SCCS and others) about ingredients — not clinical testing of this specific product. Exposure, concentration and individual sensitivity all matter. Consult a dermatologist for medical concerns.
