In a process for the homogeneous polymerization of water insoluble polymers containing greater than 50% by weight of monomers selected from the group consisting of C.sub.1 -C.sub.18 acrylate or methacrylate esters, N-substituted acryl or methacrylamides and mixtures thereof in substantially non-aqueous organic solutions, the improvement which comprises using as the polymerization initiator a water soluble initiator dissolved in sufficient amount of water to dissolve the initiator whereby the res...

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...

A hair treatment composition which can imparts an excellent set-retaining power to the hair while maintaining the natural hair texture. The hair treatment composition contains a polymer capable of forming a polymer film having a water vapor transmission coefficient, which is determined on the basis of a water vapor transmission rate measured in accordance with "Testing Methods for Determination of Water Vapor Transmission Rate of Moisture-proof Packaging Materials" [Japanese Industrial Standard ...

A hair styling composition comprising: (a) from about 0.1% to about 15%, by weight, of an adhesive polymer, said polymer being characterized by an organic polymeric backbone wherein said polymer is substantially free of silicone; (b) from about 0.1% to about 15%, by weight, of a silicone grafted adhesive polymer, said polymer being characterized by an organic polymeric backbone, compatible with said adhesive polymer of (a) wherein said silicone grafted adhesive polymer has silicone macromers gra...

Novel conditioning polymers containing (meth)acrylamidopropyltrimethyl ammonium chloride, meth(acrylic acid) or 2-(meth)acrylamido-2-methylpropane sulfonic acid and, optionally, a C.sub.1 -C.sub.22 alkyl (meth) acrylate and the use thereof in a cosmetically acceptable medium for the treatment of a keratin-containing substrate are disclosed.

The invention relates to a styling composition, packaged in an aerosol device, containing: a liquid phase containing, in a cosmetically acceptable liquid medium, at least one fixing film-forming polymer chosen from branched block copolymers containing, as main monomers, at least one C.sub.1-20 alkyl acrylate and/or at least one N-mono- or N,N-di(C.sub.2-12 alkyl)(meth)acrylamide, and acrylic acid and/or methacrylic acid, and at least one propellant.

Compositions for hair shaping and/or form retention of hair comprising, in a cosmetically acceptable aqueous medium, at least one film-forming acrylic oligomer, which is soluble or dispersible in the aqueous medium, having a molecular weight, measured by steric exclusion chromatography, of less than or equal to 50,000 and with a glass transition temperature Tg ranging from 0 to 45.degree. C. preferably comprising: a) from 20 to 45% by weight of at least one residue of a monomer (A) selected from...

Novel conditioning polymers containing (meth)acrylamidopropyltrimethyl ammonium chloride, meth(acrylic acid) or 2-(meth)acrylamido-2-methylpropane sulfonic acid and, optionally, a C.sub.1 -C.sub.22 alkyl (meth) acrylate and the use thereof in a cosmetically acceptable medium for the treatment of a keratin-containing substrate are disclosed.

In a hair cosmetic containing titanium-dioxide-coated mica, titanium-dioxide-coated mica with particle diameters of 20 .mu.m or larger is used in a proportion not more than 10% by volume in the total volume of the titanium-dioxide-coated mica so that, when applied to hair, it may not impart an unnaturally glittering impression to the hair. To improve re-dispersibility of such a hair cosmetic, a carboxyvinyl polymer and an amphoteric macromolecule may be used in combination.

The present invention relates to water or alcohol soluble or dispersible thermoplastic elastomeric copolymers and to cosmetic and pharmaceutical compositions containing these copolymers. This invention especially relates to copolymers useful for hair styling purposes, and to hair styling compositions containing these copolymers. This invention further relates to copolymers useful for providing cosmetic and pharmaceutical compositions for topical application to the skin. These topical skin care c...
