A hair cosmetic composition having an excellent hair setting property, and which imparts to hair good flexibility and a good finish feeling. The hair cosmetic composition comprises (a) a water-soluble amine-oxide-containing polymer having a weight-average molecular weight of 10,000 to 500,000 and (b) a water-soluble polymer selected from the group consisting of nonionic, cationic, anionic and amphoteric polymers. The weight ratio of component (a) to component (b) falls within a range of from 1:10 to 10:1. Components (a) and (b) are incorporated in a total amount of from 0.1 to 10 wt. % based on the hair cosmetic composition.

Hair cosmetic composition containing amine-oxide polymer

A polymer suitable for use in hair care products comprising a copolymer comprising

Hair-care products containing copolymers formed from unsaturated

A hair cosmetic composition containing a graft copolymer or an alternating block copolymer, each of which comprises a first unit containing a polysiloxane group and a second unit containing a polymer of unsaturated monomers is provided. The first and second units are linked by sulfide linkage. The hair cosmetic composition provides hair with softness, luster, combing smoothness, styling ease, enhanced volume, and has good hairstyle retainability and damage-restoring characteristics.

Hair cosmetic compositions comprising sulfide linked polysiloxanes

A polymer suitable for use in hair care products comprising a copolymer comprising (a) a unit of a hydrophilic ethylenically unsaturated monomer such as dimethylaminoethyl methacrylate in a quantity of 15 to 99.9% by weight; (b) a unit of an ethylenically unsaturated monomer having a polysiloxane group such as: ##STR1## in a quantity of 0.1 to 85% by weight; and (c) a unit of an optional hydrophobic unsaturated monomer such as lauryl methacrylate in a quantity of 0 to 84.9% by weight.

Polymer for hair-care products

A hair setting gel composition comprising (A) from 0.2 to 5% by weight of a partially of completely neutralized salt of a crosslinked carboxyvinyl polymer, (B) from 0.5 to 10% by weight of an amphoteric resin, and (C) from 85 to 99.5% by weight of a solvent mainly comprising water and/or a lower alcohol, with the total of the components (A), (B) and (C) being 100% by weight. The gel composition is excellent in transparency and hair setting performance.

Hair setting gel composition

A thermoplastic resin film having improved printability is described, which is formed by coating a polyolefin film with an aqueous solution containing a modified polyethylene-imine represented by the following general formula: ##STR1## where A is ##STR2## or a polyamine-polyamide residue; R.sub.1 -R.sup.4 are each independently H, an alkyl or alkenyl group having 1-24 carbon atoms, an alicyclic hydrocarbon group or a benzyl group, provided that at least one of R.sup.1 -R.sup.4 is a group other than H; m is 0-300; and n, p and q are each a number of 1-300, and drying the coated solution to form a surface coating.

Thermoplastic resin film having improved printability

A hair-conditioning resin composition prepared by modifying a copolymer resin with a zwitterionizing agent is described, said copolymer resin being prepared by copolymerizing in a hydrophilic solvent a polymerizable mixture containing

Resin compositions having hair-conditioning property

A resin for hairdressing is obtained by: copolymerizing in a hydrophilic solvent a monomer (1), which is specific derivative of acrylic or methacrylic acid, and a monomer (3), which is a specific (meth)acrylic acid ester, and, optionally in addition, any of a monomer (2), which is another specific (meth)acrylic acid ester, and monomer (4), which is a hydrophilic ethylenically unsaturated monomer, and a monomer (5), which is an ethylenically unsaturated monomer other than the monomers (1) through (4); causing the copolymer thus formed to react in the state of a solution in a hydrophilic solvent with sodium or potassium haloacetate; removing any precipitate formed as by-product; and, if necessary, subjecting the copolymer solution thus obtained to an ion-exchange resin treatment thereby to remove ionic impurities.
