Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not explicitly assessed this specific polymer, classifying its data as 'insufficient.' However, the panel reviewed related hexamethylene diisocyanate (HDI) polymers, concluding 17 were safe for cosmetic use provided residual isocyanate monomers were negligible. While SkinSAFE deems it 'Teen SAFE' and 'Irritant Free,' implying a favorable consumer safety profile, one independent source categorizes it as 'Muy Dudoso' (Very Doubtful) with an unspecified restriction, presenting a conflicting safety perspective.

Verdict
Despite its film-forming properties and apparent low irritancy from some sources, the ingredient's 'insufficient data' status from CIR, primary use in nail products, and conflicting safety assessments warrant caution for its application in precision skincare formulations.
