Shampooing Stop Pellicules + anti-démangeaisons — ingredient safety report

• Hormone disruption:Classified as toxic to reproduction (CMR 1B); banned in the EU since March 2022.
• Allergy risk:Well-documented fragrance sensitizer.

The lily-of-the-valley scent 'Lilial', banned in EU cosmetics in 2022 after being classified as presumed toxic to human reproduction. Still legal in some other markets — check older or imported products.

• Cancer concern:Slowly releases formaldehyde, an IARC Group 1 carcinogen.
• Allergy risk:Frequent cause of preservative contact dermatitis.

A formaldehyde-releasing preservative used in creams, shampoos and wipes. The slow formaldehyde release preserves the product but exposes skin to a known carcinogen and allergen.

• 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.

• 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.

• 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.

• 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:Occasional irritation/allergy.
• Environmental impact:Highly toxic to aquatic organisms; banned in EU cosmetics since 2022 as a reprotoxic CMR.

The classic dandruff active banned in EU cosmetics in 2022 (reproductive-toxicity classification) but still standard in US shampoos.

• 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 violet-type scent chemical requiring EU allergen declaration.

• Environmental impact:Synthetic polymer counted as a microplastic under the EU restriction when in particle form.

A common film-forming polymer scrutinized under the EU's microplastics restriction; skin safety itself is well established.

• Allergy risk:Rare hypersensitivity reactions, better documented in food than cosmetics.

Tartrazine yellow dye; approved for cosmetics with rare sensitivity reactions reported.
