AKA: Film Former, Polymer Emollient
Plant-Derived
Not Clean
OriginDerived from hydrogenated dimer dilinoleyl alcohol, a polyol compound synthesized from plant-based linoleic acid sources. Produced through polymerization and hydrogenation of dimer diols with hexamethylene diisocyanate (HDI) to form a crosslinked polymer.
