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.

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.

DMDM Hydantoin

preservative

Severity 7/10
Sensitive skin: High cautionPregnancy: Use with cautionBabies & kids: Best avoidedEczema-prone: Best avoided
  • Cancer concern:Slowly releases formaldehyde, an IARC Group 1 carcinogen.
  • Allergy risk:Frequent cause of preservative contact dermatitis.

A formaldehyde-releasing preservative used in creams, shampoos and wipes. The slow formaldehyde release preserves the product but exposes skin to a known carcinogen and allergen.

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.

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.

Laureth-4

emulsifier

Severity 4/10Editorial
Oily & acne-prone: High caution
  • Pore-clogging:Rates high on comedogenicity scales.

An emulsifier that scores relatively high for pore-clogging potential in classic comedogenicity testing.

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.

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.

Lactic Acid

exfoliant · humectant

Severity 3/10Editorial
Sensitive skin: Use with cautionBabies & kids: Use with cautionEczema-prone: Use with caution
  • Irritation:Milder than glycolic; still increases photosensitivity.

A gentler AHA that exfoliates and hydrates simultaneously; the usual pick for drier or more reactive skin starting acids.

Dimethiconol

emollient

Severity 3/10Editorial
  • Environmental impact:Persistent silicone, like dimethicone.

A silicone gum for silky slip; skin-inert with the family's usual environmental-persistence criticism.

Dimethicone

emollient · occlusive

Severity 3/10Editorial
  • Environmental impact:Not biodegradable; accumulates in the environment via wash-off.

The workhorse silicone — inert and non-sensitizing on skin (even FDA-approved as a skin protectant), with persistence in the environment as its main criticism.

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.

Mica

pigment · pearlescent

Severity 2/10Editorial
  • Environmental impact:Skin-safe; the ingredient's controversy is ethical (mining labor), not toxicological.

The shimmer mineral in highlighters and glowy creams; safe on skin, with sourcing ethics being its real controversy.

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.

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 (4)

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 (14)

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

Recognized ingredients (1)

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.

  • sodium polynaphtalenesulfonate

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.
