Research published in the American Chemical Society's Applied Polymer Materials describes a technique to assess the tack properties hair styling polymers.
Scientists from Technische Universität München devised the approach utilizing nylon fiber assemblies coated with pressure-sensitive adhesives; e.g., polymer blends. Cylindrical stamps are then contacted with the fibers to measure tackiness. For additional details, see the complete article.
Styling products with a natural feel are generally preferred by today's consumers. As such, measuring their tack property during development could support the formulator's efforts toward creating soft, natural feeling hair styling agents.
