Anti-transpirant Extra Dry — 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; 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; oxidation products are potent sensitizers.

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

• 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; lemon-scented sensitizer.

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

• Irritation:Sensory irritant; the cooling feeling signals nerve stimulation, not soothing.

The cooling molecule from mint. Refreshing on healthy skin but a genuine irritant for reactive, broken or infant skin.

• Allergy risk:One of the 26 EU-declarable fragrance allergens.
• Irritation:Mild irritation possible at higher concentrations.

A preservative and fragrance component that must be declared on EU labels because it can trigger contact allergy in a small share of users.

• 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.

• Irritation:Can irritate freshly shaved underarm skin.

The standard antiperspirant active. Large reviews and the EU's scientific committee found no supported link to breast cancer or Alzheimer's at cosmetic exposure levels.
