Abstract
The present invention relates to hair care compositions which contain a polymer which is prepared from N-vinyl formamide (NVF) monomer and the use of those hair care compositions to treat hair. The polymer may be a homopolymer of NVF or an interpolymer of NVF 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.
Claims22
A hair care composition, comprising:
- from about 0.1 to about 15 weight percent of a polymer which is prepared via free-radical initiated polymerization, wherein the polymer is selected from the group consisting of a homopolymer prepared from N-vinyl formamide monomer and an interpolymer prepared from at least 10 weight percent N-vinyl formamide monomer, and a vinyl monomer;
- and
- an ingredient selected from the group consisting of a conditioning agent, an emulsifier, a surfactant, a viscosity modifier, a gelling agent, an opacifier, a stabilizer, a preservative, a sequestering agent, a chelating agent, a pearling agent, a clarifying agent, a fragrance, a colorant, a propellant, an organic solvent and water.
