The present invention involves using mechanized strategies to fabricate test samples as well as strategies for selecting sample substrates. These strategies significantly reduce the effort and the variabilities associated with making test samples and testing hair fixative compositions. The technology allows simple, rapid, inexpensive evaluation of hair fixative compositions in a way that generates consistent, reliable data. The quality of the data is high enough to facilitate easier qualitative and quantitative comparisons among compositions under investigation. In preferred modes of practice, the present invention provides a simple way to screen new polymer systems and other developmental products. Additionally, this invention can be used to generate more meaningful comparative data for customer and personal care industry presentations.

This invention relates to vinyl ether-based coatings for which properties such as color stability, thermal stability, mechanical stability, hydrolytic stability, and resistance to embrittlement may be maintained and properties hydrogen generation and blocking are minimized. The coatings comprise a vinyl ether-containing composition polymerizable by actinic, gamma ray, or electron beam radiation comprising: (a) an oligomer or a mixture of oligomers which are monofunctional, multifunctional, or a mixture of both monofunctional and multifunctional and which have a reactive functionality chosen from the group consisting of epoxy, acrylate, vinyl ether, maleate, or mixtures thereof; (b) monomers which are monofunctional, multifunctional, or a mixture of both monofunctional and multifunctional monomers and which have a reactive functionality chosen from the group consisting of epoxy, acrylate, vinyl ether, maleate, or mixtures thereof, wherein at least one of (a) or (b) must contain a vinyl ether functionality; (c) a photoinitiator, optionally including a sensitizer, chosen from the group consisting of a cationic photoinitiator and a radical photoinitiator; and (d) a thermal oxidation stabilizer. Adhesion to a substrate, particularly glass, is achieved by coupling agents including vinyl ether urethane siloxane compounds.
