Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined this ingredient, as part of the broader Hexamethylene Diisocyanate (HDI) Polymer group, to be safe for cosmetic use under current practices, concluding that there are no significant residual isocyanate monomers. However, a notable concern arises from its ethoxylated nature; ethylene oxide, a known carcinogen, is employed in the ethoxylation process, leading one authority to label it 'Very Doubtful' ('Muy Dudoso') due to this manufacturing aspect and the prevalence of ethoxylated compounds in cosmetics.
