Abstract:
ELYSAN W is a water-based polyurethane dispersion (WPUD) used as a film-forming agent in cosmetic applications. This study focuses on optimizing the product using bio-based polyols, aiming to develop a more sustainable alternative to petroleum-derived products. To achieve this, various synthesis parameters were modified—such as chain extender equivalents, polyol combinations, and catalyst usage, among others. Although formulations yielding results very close to those of the reference product were obtained, full optimization was not achieved.
