Abstract: Ethanol soluble or dispersible polyetheramide polymers that have a percent elongation to break of less than 100%. The polymers are formed from a reaction mixture comprising at least one or more poly(alkyleneoxy)diamines and one or more diacids. The reaction mixture can optionally include one or more aliphatic diamines in addition to the one or more poly(alkyleneoxy)diamines. The polyetheramide polymers have application in personal care compositions such as hair fixative compositions, for example, hair spray formulations.

Abstract: A skin care formulation includes a dispersion or emulsion including at least one particle-polymer hybrid and a cosmetically acceptable additive. The polymer-particle hybrid includes at least one particle grafted with at least one polymer. The skin care formulation provides improved water-resistance with limited impact on the sensory feel of the formulation (such as tackiness).

Abstract: The present invention relates to hair care compositions which contain a polymer which is prepared from N-vinyl acetamide (NVAM) monomer and the use of those hair care compositions to treat hair. The polymer may be a homopolymer of NVAM or an interpolymer of NVAM and at least one vinyl monomer. The polymer is present in amounts effective to provide the hair care compositions with hair fixative properties and/or hair conditioning properties.

Abstract: The present invention is directed to precipitation polymerization processes for the manufacture of essentially non-crosslinked polymers prepared from N-vinyl acetamide monomer which exhibit reduced levels of residual non-polymerizable contaminants, particularly residual acetamide, the processes including the steps of contacting the N-vinyl acetamide monomer with a polymerization medium containing a diluent selected from ethyl acetate and acetone and a free-radical initiator, under conditions effective to polymerize the N-vinyl acetamide monomer, thereby forming a precipitate of the polymer in the polymerization medium; and isolating the precipitated polymer from the polymerization medium.

Abstract: The present invention is directed to precipitation polymerization processes for the manufacture of polymers prepared from N-vinyl formamide monomer, the processes including the steps of contacting the N-vinyl formamide monomer with a polymerization medium containing t-butanol as diluent and a free-radical initiator, under conditions effective to polymerize the N-vinyl formamide monomer, thereby forming a precipitate of the polymer in the polymerization medium, substantially isolating the precipitated polymer from the polymerization medium, contacting the substantially isolated polymer with a wash containing a different diluent than the t-butanol used in the polymerization and isolating the washed polymer from the wash.

Abstract: The present invention relates to hair conditioning compositions which utilize as a hair conditioning additive a water-soluble polymer in amounts effective to impart hair conditioning properties to the hair conditioning composition, wherein the polymer contains the residue of N-vinyl formamide and the residue of at least one vinyl polymerizable moiety which contains an amine selected from the group consisting of secondary, tertiary and quaternary amines. The conditioning composition also includes one or more ingredients such as conditioning agents, emulsifiers, viscosity modifiers, gelling agents, opacifiers, stabilizers, preservatives, sequestering agents, chellating agents, pearling agents, clarifying agents, fragrances, colorants, and propellants; and water. The invention also relates to methods of conditioning hair.

Abstract: The present invention relates to hair fixative compositions which utilize as the hair fixative resin a polymer which is prepared from N-vinyl formamide (NVF). The polymer may be a homopolymer of NVF or an interpolymer of NVF and at least one vinyl monomer(s). The polymer is present in amounts effective to provide the inventive hair fixative compositions with hair fixative properties. In preferred embodiments, the hair fixative composition is a stable, aqueous gel which forms a clear, non-tacky film upon drying. In certain embodiments, the gel has a rheology effective to allow the gel to be applied to the hair via a spray pump.
