- Allergy risk:Named Allergen of the Year 2004; impurities (amidoamine) drive most reactions.

- Allergy risk:Occasional contact allergen (Allergen of the Year 2017 family).
A gentle sugar-based cleanser used in baby and sensitive-skin washes; allergy is uncommon but documented.
- 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.
