Dissolvant sans acétone — ingredient safety report

• Irritation:Drying and barrier-disrupting in high-alcohol formulas with regular use.

Denatured ethanol gives products a fast-drying, weightless feel, but as a leading ingredient it degrades the skin barrier with repeated use — a poor match for dry, sensitive or eczema-prone skin.

• 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.
