- Allergy risk:So allergenic the EU banned it outright in 2021.
The fragrance 'Lyral', banned in the EU since 2021 after becoming one of the most frequent causes of fragrance allergy in Europe.
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.
Babies & kids: Use with caution
- Irritation:Occasional stinging and irritation, mostly around eyes and on damaged skin.
Today's most common preservative, considered safe by the SCCS up to 1%. French authorities advise avoiding it in wipes and diaper-area products for children under 3 as a precaution.
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.
preservative booster · skin conditioning
- Irritation:Documented occasional contact allergy and eye irritation.
A preservative booster often paired with phenoxyethanol; low-risk overall with rare reports of contact allergy.
- 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.
- 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.
