Flagged ingredients (8)

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

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.

Octocrylene

uv filter

Severity 5/10Editorial
Sensitive skin: Use with cautionBabies & kids: Use with cautionEczema-prone: High caution
  • Allergy risk:Rising cause of contact and photoallergy, especially in children.
  • Environmental impact:Accumulates in aquatic life; degrades into benzophenone over time.

A stabilizing UV filter that can degrade into benzophenone as products age, and an increasingly reported allergen — replace old tubes of octocrylene sunscreens.

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.

Cyclomethicone

emollient · solvent

Severity 6/10Editorial
Pregnancy: Use with caution
  • Environmental impact:CosIng identifies Cyclomethicone with octamethylcyclotetrasiloxane (D4), which is prohibited in EU cosmetics (Annex II) as persistent/bioaccumulative and a suspected reproductive toxicant.
EU CosIng Annex II (prohibited in cosmetics) ↗

A blanket INCI name for cyclic silicone blends. The EU CosIng database maps Cyclomethicone to D4, which is now prohibited in EU cosmetics; modern formulas replace it with D5/D6.

Severity 4/10Editorial
Sensitive skin: Use with caution
  • Allergy risk:Degradation products can cause photoallergy when unstabilized.

The main UVA filter in US sunscreens. Safe when properly stabilized, but it breaks down in sunlight into potentially sensitizing fragments in poorly formulated products.

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.

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.

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.

No concerns found (15)

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.

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.

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.
