Shampooing Antipelliculaire - Parfum de Menthe — 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.

• Irritation:Milder than SLS but still drying for compromised skin.

The gentler cousin of SLS used in most mainstream shampoos and washes. Its manufacturing can leave trace 1,4-dioxane, which reputable makers strip out — an issue of quality control rather than the ingredient itself.

• 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:Named Allergen of the Year 2004; impurities (amidoamine) drive most reactions.

A mild coconut-derived surfactant in countless 'gentle' cleansers. Most allergy is caused by manufacturing impurities, so quality varies by brand.

• 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 fixative on the EU allergen list, with early-stage evidence of weak hormonal activity being evaluated by regulators.

• Allergy risk:Rare reports of sensitivity.

A widely approved blue dye with a benign cosmetic safety record.
