Abstract:
The continuous demand for versatile cosmetic products drives companies to experiment with new formulations. Polyurethanes, known for their diverse range of properties, are commonly utilized as film-formers in hair-care products. This study focuses on the development of an autonomous film-forming polyurethane with exceptional hydrophobicity, aimed at enhancing water-resistance in hair. Multiple prototypes were synthesized, incorporating variations in keratin-reactive groups, polyol composition, and ionomer concentration. The effectiveness of these prototypes was assessed through various characterization techniques, including pH analysis, dynamic light scattering (DLS). Furthermore, synthetic hair samples were subjected to scanning electron microscopy (SEM) to evaluate the performance of the different prototypes
