Essence Ultîme Citrus Oil Luminous Blond Shampooing illuminant — 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; 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.

• Allergy risk:American Contact Dermatitis Society Allergen of the Year 2018.
• Irritation:Can irritate compromised skin at higher concentrations.

A workhorse humectant and penetration enhancer that is fine for most, but a recurring culprit in eczema patients' patch tests.

• 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 fragrance allergen.

A common jasmine-scented ingredient in fine fragrance and skincare, declared as an allergen on EU labels.

• 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:Occasional stinging and irritation, mostly around eyes and on damaged skin.

Today's most common preservative, considered safe by the SCCS up to 1%. French authorities advise avoiding it in wipes and diaper-area products for children under 3 as a precaution.

• Cancer concern:IARC 2B by inhalation only — relevant to loose powders and sprays, not creams.

A mineral UV filter and pigment that is one of the safest sunscreen choices in cream form; the inhalation-based cancer classification only matters for powder and spray formats.

• Allergy risk:Rare Asteraceae cross-reactions in ragweed-allergic individuals.

A gentle calming botanical; the rare reactions occur mostly in people allergic to ragweed-family plants.

• Irritation:Can cause transient, non-allergic flushing/stinging on reactive skin.

A food-grade preservative generally regarded as one of the gentler options; occasional non-immune stinging is its main drawback.

• Environmental impact:Skin-safe; the ingredient's controversy is ethical (mining labor), not toxicological.

The shimmer mineral in highlighters and glowy creams; safe on skin, with sourcing ethics being its real controversy.
