Shampooing doux beurre de mangue huile de riz — 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:The reference irritant used in dermatology research; strips barrier lipids.

A powerful foaming cleanser so reliably irritating that dermatology studies use it as the standard positive control for skin irritation. Fine for many in rinse-off use, but a poor match for dry, sensitive or eczema-prone 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 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: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.

• 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.
