Arom — ingredient safety report

• Allergy risk:Among the most potent of the EU-declarable fragrance allergens.

A carnation-type scent chemical and one of the strongest sensitizers among declared fragrance allergens; industry limits its use concentration.

• Irritation:Drying and barrier-disrupting in high-alcohol formulas with regular use.

Denatured ethanol gives products a fast-drying, weightless feel, but as a leading ingredient it degrades the skin barrier with repeated use — a poor match for dry, sensitive or eczema-prone skin.

• Allergy risk:Fragrance is the single most common cause of cosmetic contact allergy.
• Irritation:Frequent trigger of stinging and redness on reactive skin.

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.

• Allergy risk:One of the strongest natural fragrance allergens; strictly limited in the EU.

A classic perfume base note and one of the most potent natural sensitizers, with strict EU limits on its allergenic constituents.

• Allergy risk:EU-declarable allergen; oxidation products are potent sensitizers.

The citrus-peel scent molecule. Like linalool, it becomes allergenic mainly after oxidizing in opened products.

• 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.

• Allergy risk:EU-declarable allergen; clove-scented sensitizer.

The clove scent molecule, a long-established contact allergen on the EU declaration list.

• 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.

• Allergy risk:EU-declarable allergen; use concentrations limited by industry standards.

A synthetic lily-of-the-valley scent and well-documented contact allergen.

• Allergy risk:EU-declarable allergen; lemon-scented sensitizer.

The lemon-scent molecule in lemongrass and citrus oils, a recognized contact allergen requiring EU label declaration.

• Allergy risk:EU-declarable fragrance allergen.

A rose-type scent component on the EU's mandatory-declaration allergen list.

• Allergy risk:EU-declarable allergen found in tonka bean and many perfumes.

A sweet hay-scented molecule requiring EU allergen declaration; a regular positive in fragrance patch-test series.

• Allergy risk:EU-declarable fragrance allergen.

A floral scent molecule with deodorizing properties, on the EU's mandatory allergen declaration list.
