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

Severity 8/10Editorial
Sensitive skin: Best avoidedPregnancy: Use with cautionBabies & kids: Best avoidedEczema-prone: Best avoided
  • Allergy risk:Potent sensitizer, typically blended with MIT (Kathon CG).
  • Irritation:Corrosive in concentrate; irritating at use levels.
Caredermis curated dermatological review

The chlorinated partner of MIT, restricted in the EU to rinse-off products only. A leading cause of preservative contact dermatitis worldwide.

Severity 8/10
Sensitive skin: Best avoidedPregnancy: Use with cautionBabies & kids: Best avoidedEczema-prone: Best avoided
  • Allergy risk:Caused an epidemic of contact allergy; banned in EU leave-on products.
  • Irritation:Irritating even in people without allergy.

A preservative behind one of the largest contact-allergy epidemics in cosmetic history. The EU banned it from leave-on products and restricts it in rinse-off products to 15 ppm.

Parfum

fragrance

Severity 7/10Editorial
Sensitive skin: Best avoidedPregnancy: Use with cautionBabies & kids: Best avoidedEczema-prone: Best avoided
  • Allergy risk:Fragrance is the single most common cause of cosmetic contact allergy.
  • Irritation:Frequent trigger of stinging and redness on reactive skin.
Caredermis curated dermatological review

An umbrella term that can hide dozens of undisclosed scent chemicals. Fragrance is the leading cause of allergic contact dermatitis from cosmetics, and dermatologists routinely advise fragrance-free products for eczema, babies and sensitive skin.

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.

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.

Propylene Glycol

humectant · solvent

Severity 3/10Editorial
Sensitive skin: Use with cautionEczema-prone: High caution
  • Allergy risk:American Contact Dermatitis Society Allergen of the Year 2018.
  • Irritation:Can irritate compromised skin at higher concentrations.

A workhorse humectant and penetration enhancer that is fine for most, but a recurring culprit in eczema patients' patch tests.

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.

Decyl Glucoside

surfactant

Severity 2/10Editorial
  • Allergy risk:Occasional contact allergen (Allergen of the Year 2017 family).

A gentle sugar-based cleanser used in baby and sensitive-skin washes; allergy is uncommon but documented.

Sodium Benzoate

preservative

Severity 2/10Editorial
  • Irritation:Can cause transient, non-allergic flushing/stinging on reactive skin.

A food-grade preservative generally regarded as one of the gentler options; occasional non-immune stinging is its main drawback.

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 (17)

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

Recognized ingredients (4)

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.

Not enough data (1)

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.

  • HELIANTHUS ANNUUS SEED EXTRACT / SUNFLOWER SEED EXTRACT

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.
