Flagged ingredients (15)

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

Severity 6/10
Sensitive skin: High cautionPregnancy: Use with cautionBabies & kids: Use with cautionEczema-prone: Best avoided
  • Cancer concern:Releases small amounts of formaldehyde (IARC Group 1).
  • Allergy risk:Recognized contact allergen, often cross-reacting with other releasers.
EU CosIng Annex V: releases formaldehyde (IARC Group 1) ↗

A widely used formaldehyde-releasing preservative. Releases less formaldehyde than DMDM hydantoin but still triggers allergy in formaldehyde-sensitized people.

Severity 5/10Editorial
Sensitive skin: High cautionDry skin: High cautionEczema-prone: Best avoided
  • Irritation:Comparable irritation profile to SLS in leave-on contact.

A strong anionic cleanser similar to SLS, appropriate only in well-formulated rinse-off products.

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.
EU CLP Skin Sens. 1A ↗EU CLP Skin Corr. 1B ↗EU CLP Eye Dam. 1 ↗EU CLP Aquatic Acute 1/Aquatic Chronic 1 ↗Caredermis curated dermatological review

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.

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.

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.

Triethanolamine

ph adjuster · emulsifier

Severity 3/10Editorial
Sensitive skin: Use with caution
  • Irritation:Irritating at higher concentrations or in leave-on products.
  • Allergy risk:Occasional contact allergen.

A pH adjuster that is safe in itself but should not be combined with formaldehyde releasers or bronopol, which can convert it to nitrosamines.

Paraffinum Liquidum

occlusive · emollient

Severity 2/10Editorial
Oily & acne-prone: Use with caution
  • Pore-clogging:Cosmetic grade is minimally comedogenic despite its reputation.

Highly refined mineral oil is an inert, non-sensitizing emollient. Its bad reputation comes from industrial-grade oils that are never permitted in cosmetics.

Acrylates Copolymer

film former · thickener

Severity 4/10Editorial
  • Environmental impact:Synthetic polymer counted as a microplastic under the EU restriction when in particle form.

A common film-forming polymer scrutinized under the EU's microplastics restriction; skin safety itself is well established.

Disodium EDTA

chelating agent

Severity 3/10Editorial
  • Environmental impact:Poorly biodegradable; can remobilize heavy metals in waterways.

A metal-binding stabilizer that is safe on skin at the tiny amounts used; its criticism is environmental persistence.

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 (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 (13)

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.

  • AMMONIUM SULFATE· viscosity controlling
  • DIMETHICONE PROPYL PG-BETAINE· antistatic, cleansing, hair conditioning…

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.
