Expert Verdict

Residual HDI (hexamethylene diisocyanate) monomer must be strictly controlled as it is a sensitizer/irritant; standard PEG contamination concerns apply. Crosslinked structure provides unique rheological and film-forming behavior; creates structured gels in formulations; the dual PEG chains (17 and 11 EO) provide tunable hydrophilicity
