Déodorant — ingredient safety report

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

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

• Irritation:Irritating to skin and airways; 1,8-cineole content is unsuitable for infants.

A camphoraceous oil that should be kept away from the faces of babies and young children due to respiratory and skin irritation risks.

• Irritation:Phototoxic; increases sunburn risk on exposed skin.
• Allergy risk:High limonene content oxidizes into sensitizers.

A citrus oil that is both phototoxic in sunlight and increasingly allergenic as its limonene oxidizes.

• 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 with well-documented sensitization.

A rose/geranium scent molecule and one of the more frequently positive fragrance allergens in patch testing.

• Allergy risk:Oxidized tea tree oil is a well-documented contact allergen.
• Irritation:Irritating when used undiluted or at high concentrations.

A popular natural antibacterial for blemishes that becomes increasingly allergenic as it ages and oxidizes; never use it undiluted.

• 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 allergen; clove-scented sensitizer.

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

• Allergy risk:EU-declarable fragrance allergen.

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

• Allergy risk:EU-declarable fragrance allergen.

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

• Irritation:Documented occasional contact allergy and eye irritation.

A preservative booster often paired with phenoxyethanol; low-risk overall with rare reports of contact allergy.
