BIOSTYLE® XH polymer is a naturally-derived film-forming polymer designed for use in clear, stiffer holding hair gels, mousses, and other working styling aids where volumizing properties are desired. BIOSTYLE XH polymer provides the on-hair performance, exceptional clarity, and consumer preferred rheology that are typically associated with synthetic fixative polymers, yet BIOSTYLE XH polymer is partially derived from renewable resources. This high molecular weight, proprietary hybrid polymer represents a new way for formulators to create more sustainable, harder holding styling products while maintaining cost-in-use targets without any sacrifice of performance properties.
