- 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.

- 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.

- 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.
Sensitive skin: High cautionEczema-prone: Best avoided
- Allergy risk:Potent EU-declarable allergen; the cinnamon scent molecule.
- Irritation:Can cause immediate stinging and flushing.
The cinnamon scent molecule, a strong sensitizer and irritant that appears in fragrance blends and lip products.
Oily & acne-prone: High caution
- Pore-clogging:High comedogenicity rating in classic testing.
A close relative of isopropyl myristate with a similar pore-clogging reputation for acne-prone skin.
Sensitive skin: Use with cautionEczema-prone: High caution
- Allergy risk:EU-declarable allergen; clove-scented sensitizer.
The clove scent molecule, a long-established contact allergen on the EU declaration list.
Sensitive skin: Use with cautionEczema-prone: High caution
- Allergy risk:EU-declarable allergen with well-documented sensitization.
A rose/geranium scent molecule and one of the more frequently positive fragrance allergens in patch testing.
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.
Sensitive skin: Use with caution
- Allergy risk:EU-declarable fragrance allergen.
A jasmine-type scent chemical on the EU mandatory declaration list.
Sensitive skin: Use with caution
- Allergy risk:EU-declarable fragrance allergen.
A floral fixative on the EU allergen list, with early-stage evidence of weak hormonal activity being evaluated by regulators.

- Allergy risk:EU-declarable fragrance allergen.
A rose-type scent component on the EU's mandatory-declaration allergen list.
Sensitive skin: Use with caution
- Allergy risk:EU-declarable fragrance allergen.
A common jasmine-scented ingredient in fine fragrance and skincare, declared as an allergen on EU labels.
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.
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.
- 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.
occlusive · skin protectant
Severity 2/10Editorial- Cancer concern:Concern applies only to unrefined grades containing PAHs; cosmetic grade is highly refined (EU-mandated).
The most effective occlusive known and a staple of eczema care. The cancer concern belongs to unrefined industrial grades — pharmaceutical-grade petrolatum in cosmetics is rigorously purified.
