Expert Verdict

Ethoxylated surfactant with 1,4-dioxane contamination risk. Must test residual 1,4-dioxane per NY DEC limits (โ‰ค2 ppm from 12/31/2023, โ‰ค1 ppm from 12/31/2025) and ensure vacuum stripping or equivalent purification. Ethylene oxide residues should also be verified. Limited CIR/SCCS data; safety inferred from broader alkyl PEG ether class.
