Bis-C16-20 Isoalkoxy Tmhdi/PEG-90 Copolymer
What is Bis-C16-20 Isoalkoxy Tmhdi/PEG-90 Copolymer?
Bis-C16-20 Isoalkoxy Tmhdi/PEG-90 Copolymer is a high molecular weight synthetic polymer created from tetramethylxylene diisocyanate (TMHDI), polyethylene glycol (PEG-90), and C16-20 isoalkoxy alcohols. It belongs to the class of polyurea-PEG copolymers commonly found in hair care formulations, particularly styling sprays and mousses. In cosmetics, it functions by depositing a thin, elastic film on the hair shaft upon drying. This film adheres lightly, offering structure and control to hairstyles without rigidity or flaking. The branched isoalkoxy chains contribute to its flexibility and compatibility with hair, while the PEG component enhances water solubility and even application. It is typically used at low concentrations to achieve hold while maintaining a natural feel.
Benefits
Delivers flexible hold for hairstyles that lasts through daily activities.
