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.
Claims19
A hair fixative composition comprising, from about 0.5 to about 15 weight percent of a polymer prepared from N-vinyl formamide, wherein the polymer is selected from the group consisting of a homopolymer of N-vinyl formamide and an interpolymer of N-vinyl formamide and at least one vinyl monomer(s), a gelling agent in an amount effective to form a hair fixative gel;
- and a solvent selected from the group consisting of water, organic solvents, or mixtures thereof, wherein the hair fixative composition exhibits high humidity curl retention.
A method of fixing hair, comprising applying to the hair a hair fixative composition comprising from about 0.5 to about 15 weight percent of a polymer prepared from N-vinyl formamide, wherein the polymer is selected from the group consisting of a homopolymer of N-vinyl formamide and an interpolymer of N-vinyl formamide and at least one vinyl monomer(s), a gelling agent in an amount effective to form a hair fixative gel;
- and a solvent selected from the group consisting of water, organic solvents, or mixtures thereof, wherein the hair fixative gel exhibits high humidity curl retention.
