Expert Verdict

Very high EO count (23) makes it highly hydrophilic with low irritation potential; standard ethoxylation-related 1,4-dioxane residual risk; CIR-reviewed as part of the pareth family.. With 23 average moles of ethylene oxide, this is one of the most hydrophilic members of the C12-13 pareth series, yielding very high HLB values. Excellent for solubilizing lipophilic actives and fragrance oils into clear aqueous systems and for stabilizing fine O/W emulsions.
