Expert Verdict

The sodium analogue carries GHS warnings for skin irritation (H315), serious eye irritation (H319), and respiratory irritation (H335); the magnesium salt is expected to behave similarly at concentrated forms. Sulfonate-based chemistry (not a sulfate), which generally confers better mildness; lauryl (C12) chain with hydroxypropyl linkage; synthetic/plant origin
