Soin hydratant — 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:Rising cause of contact and photoallergy, especially in children.
• Environmental impact:Accumulates in aquatic life; degrades into benzophenone over time.

A stabilizing UV filter that can degrade into benzophenone as products age, and an increasingly reported allergen — replace old tubes of octocrylene sunscreens.

• 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:Degradation products can cause photoallergy when unstabilized.

The main UVA filter in US sunscreens. Safe when properly stabilized, but it breaks down in sunlight into potentially sensitizing fragments in poorly formulated products.

• 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.

• Irritation:Above ~10% it becomes keratolytic and can sting on broken skin.

A natural moisturizing factor: hydrating below 10%, callus-softening above. Valuable in eczema care despite stinging on open skin.

• Irritation:Documented occasional contact allergy and eye irritation.

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

• Environmental impact:Poorly biodegradable; can remobilize heavy metals in waterways.

A metal-binding stabilizer that is safe on skin at the tiny amounts used; its criticism is environmental persistence.

• Allergy risk:Rare reports of sensitivity.

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