Shine Define — 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:So allergenic the EU banned it outright in 2021.

The fragrance 'Lyral', banned in the EU since 2021 after becoming one of the most frequent causes of fragrance allergy in Europe.

• Allergy risk:EU-declarable allergen; use concentrations limited by industry standards.

A synthetic lily-of-the-valley scent and well-documented contact allergen.

• 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 with well-documented sensitization.

A rose/geranium scent molecule and one of the more frequently positive fragrance allergens in patch testing.

• 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.

• Environmental impact:Toxic to coral; banned in Hawaii alongside oxybenzone.

A UVB filter under regulatory re-review for hormonal effects and banned in some reef regions; steadily being replaced by newer filters in modern sunscreens.

• Allergy risk:EU-declarable fragrance allergen.

A jasmine-type scent chemical on the EU mandatory declaration list.

• 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 transient stinging or redness on sensitive skin.

A mild food-grade preservative usually paired with sodium benzoate; well tolerated by most skin types.

• Environmental impact:Classified vPvB (very persistent, very bioaccumulative); EU restricts it in cosmetics from 2027.

A volatile silicone giving that silky slip, now being phased down in the EU because it persists and accumulates in aquatic ecosystems.

• Environmental impact:Not biodegradable; accumulates in the environment via wash-off.

The workhorse silicone — inert and non-sensitizing on skin (even FDA-approved as a skin protectant), with persistence in the environment as its main criticism.
