- 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:Oxidized tea tree oil is a well-documented contact allergen.
- Irritation:Irritating when used undiluted or at high concentrations.
A popular natural antibacterial for blemishes that becomes increasingly allergenic as it ages and oxidizes; never use it undiluted.
Sensitive skin: Use with cautionEczema-prone: High caution
- 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.

- Irritation:Sensory irritant; the cooling feeling signals nerve stimulation, not soothing.
The cooling molecule from mint. Refreshing on healthy skin but a genuine irritant for reactive, broken or infant skin.
Sensitive skin: Use with cautionEczema-prone: High caution
- 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.

- Irritation:The cooling sensation is mild sensory irritation; can burn on damaged skin.
Provides a fresh tingle that is actually mild irritation; problematic on compromised or young skin.

Rubbing alcohol; used as a solvent in some products and drying to skin in meaningful concentrations.

- 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.

- Allergy risk:EU-declarable fragrance allergen.
A rose-type scent component on the EU's mandatory-declaration allergen list.
- Allergy risk:Rare reports of sensitivity.
A widely approved blue dye with a benign cosmetic safety record.
- 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.
