Historically, several fixatives for light microscopy have been used, and some are favored today because of their ability to preserve certain morphologic features of interest.
Mousse continues to be a viable product category and Kao researchers have, interestingly, described foams comprising any cationic polymer and any aqueous thickening polymer in combination with volatile and non-volatile silicones and fixative polymers give good foam, good cracking sound when the foam collapses and good hold properties on the hair.
Gels formulated with Maltodextrin/VP copolymer feature equivalent fixative polymer performance as compared to gels based on market-leading synthetic polymers, thereby allowing the development of more naturally derived gels and styling products without compromise on performance or product aesthetic properties.
