Abstract (en)
[origin: WO9967216A1] What is described herein are derivatized polymers of alpha -olefin-maleic anhydride alkyl half-ester or full acid, preferably the isobutylene compound, optionally with repeat units of maleamic acid and/or its corresponding maleimide therein. These polymers are useful as fixatives in personal care products, such as hair spray compositions, particularly as one-phase, low VOC formulations in pump and aerosol systems, and in anhydrous, alcoholic, aqueous-alcoholic and in high hydrocarbon tolerant solvent formulations. In use, these hair spray compositions dry down to form clear, continuous and defectless films.
