Abstract: Natural feel polymers exhibit an advantageous blend of flexibility and a strong affinity to natural fibers imparting a natural feel when applied to keratin-based fibers, e.g. hair, skin, or textiles, e.g. cotton, wool, and are water-soluble and water-resistant. The polymers include repeat units of a monomer (e.g. ?-olefin) maleic anhydride alkyl half-ester or full acid, maleamic acid and maleimide, which are derivatized with a polyether amine.

Abstract: Personal care compositions, particularly hair care products, include a polymer mixture made from (A) a derivatized polymer of maleic anhydride having defined repeat units of a monomer (e.g. ?-olefin) maleic anhydride alkyl half-ester or full acid, maleamic acid and maleimide, and (B) a compound or polymer having a carboxylic acid functionality. These compositions exhibit excellent high humidity curl retention properties, as well as an advantageous blend of toughness and cohesiveness, and a strong affinity to natural fibers such as keratin-based fibers, e.g. hair, skin, or textiles, such as cotton or wool; and they are also water-soluble and water-resistant.

Abstract: What is described herein is a tough yet flexible polymer which is polyvinyl alcohol grafted with a water or alcohol soluble monomer. The grafted polymer has strong holding properties and high humidity resistance, which are particularly suitable for use in hair styling and skin care products. The grafted polymer preferably is made in a solvent such as water, alcohol and water-alcohol mixtures, in the presence of an initiator.

Abstract: 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.

Abstract: This invention describes hydroxyamino-derivatized polymers of .alpha.-olefin-maleic anhydride in the form of their maleimide, maleamic acid and .alpha.-olefin-maleic anhydride half-acid/half ester or full acid repeat units process for making same. The polymers are made by reacting an .alpha.-olefin-maleic anhydride, half-acid/half-ester or full acid with a hydroxy containing .alpha.-unsubstituted primary amine in aqueous or aqueous alcoholic solution at a temperature of about 60.degree.-160.degree. C. during a reaction period of about 1-25 hours.

Abstract: A process for making a free-flowing, compressible powder by spraying a selected amount of an aqueous solution of polyvinylpyrrolidone onto a fluid bed containing a predetermined admixture of starch and polyvinylpyrrolidone therein, and drying. An active-containing tablet then is provided by adding an active material, optionally with a lubricant, to such powder, and compressing the admixture into a commercially acceptable tablet.
