Expert Verdict
Critical: Low-EO alkyl PEG ethers are significantly more irritating and more readily absorbed. Laureth-4 dermal LD₅₀ in rabbits was only 0.93–1.78 mL/kg. Higher penetration enhancement potential. Residual ethylene oxide/1,4-dioxane still applies. Must be formulated to be nonirritating — this is harder to achieve with low-EO ethoxylates
