Expert Verdict
Highest ethoxylation degree in this series amplifies the need for strict 1,4-dioxane and ethylene oxide residual testing. At 42 EO units, this is the most hydrophilic member of the arachideth family; the long C20 alkyl chain still provides robust anchoring into oil phases despite the very high HLB value
