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.

Sodium Laureth Sulfate

surfactant · foaming agent

Severity 4/10Editorial
Sensitive skin: High cautionDry skin: Use with cautionBabies & kids: Use with cautionEczema-prone: High caution
  • Irritation:Milder than SLS but still drying for compromised skin.

The gentler cousin of SLS used in most mainstream shampoos and washes. Its manufacturing can leave trace 1,4-dioxane, which reputable makers strip out — an issue of quality control rather than the ingredient itself.

Severity 4/10Editorial
Sensitive skin: Use with cautionBabies & kids: Use with cautionEczema-prone: High caution
  • Irritation:Irritating to skin and airways; 1,8-cineole content is unsuitable for infants.

A camphoraceous oil that should be kept away from the faces of babies and young children due to respiratory and skin irritation risks.

Menthol

cooling agent · fragrance

Severity 4/10Editorial
Sensitive skin: High cautionBabies & kids: Use with cautionEczema-prone: High caution
  • Irritation:Sensory irritant; the cooling feeling signals nerve stimulation, not soothing.

The cooling molecule from mint. Refreshing on healthy skin but a genuine irritant for reactive, broken or infant skin.

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.

Potassium Sorbate

preservative

Severity 2/10
  • Irritation:Occasional transient stinging or redness on sensitive skin.

A mild food-grade preservative usually paired with sodium benzoate; well tolerated by most skin types.

CI 19140

colorant

Severity 3/10Editorial
  • Allergy risk:Rare hypersensitivity reactions, better documented in food than cosmetics.

Tartrazine yellow dye; approved for cosmetics with rare sensitivity reactions reported.

CI 42090

colorant

Severity 2/10Editorial
  • Allergy risk:Rare reports of sensitivity.

A widely approved blue dye with a benign cosmetic safety record.

Pore-clogging potential (2)

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.

  • Magnesium Chloride· viscosity controlling
  • Magnesium Nitrate· hair conditioning

Not enough data (4)

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.

  • C10-30 Alkyl Acrylate Crosspolymer
  • Tea Tree Leaf Oil
  • Spearmint Leaf Oil
  • Camphor Bark Oil

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.
