Alcosperse 4961 is a film former that provides excellent humidity resistance and hold when used in anhydrous or 80% VOC hair sprays. In hair spray systems, it offers improved stiffness, durability, and long-lasting hold compared to Alcosperse polymer. In addition, the AMPHOMER 4961 polymer version provides improved compatibility with thickening agents (e.g. Carbomer) for hard holding styling gels and other styling aids.
