A cosmetic composition for the first stage of an operation for the permanent reshaping of keratinous material, in particular the hair, which consists in reducing the disulphide bonds of keratin, characterized in that it comprises at least one active agent suitable for the reduction of the disulphide bonds of keratin, at least one basifying agent chosen from ornithine, a salt of ornithine, lysine, a salt of lysine, arginine, and a salt of arginine, and at least one cationic polymer containing primary, secondary or tertiary amine groups or quaternary ammonium groups in the main chain. A process for the treatment of keratinous material, in particular the hair, for the purpose of obtaining a permanent reshaping of the latter, in particular in the form of permanent-waved hair, the said process being characterized in that it includes the following steps: (i) a composition as defined above is applied to the keratinous material to be treated, the means (rollers) necessary for placing the keratinous material under mechanical tension being implemented before, during or after the said application, (ii) the keratinous material thus treated is then rinsed, (iii) an oxidizing composition is applied to the keratinous material thus rinsed, the treated keratinous material being separated from the means for placing under tension used in step (i) before or after the said application of the oxidizing composition, (iv) and, lastly, the keratinous material is rinsed again.
Novel branched or crosslinked polymers containing (meth)acrylamidopropyltrimethyl ammonium halide; (meth)acrylic acid or 2-(meth)acrylamido-2-methylpropane sulfonic acid; methylene bis-acryamide and the like; and a C.sub.4 -C.sub.22 alkyl (meth) acrylate and the use thereof in papermaking, subterranean well drilling and well cementing operations is disclosed.
Terpolymers with more than one constituent cationic monomer, further copolymerized with acrylamide, are conditioning additives for hair, skin and nail care products which, with regard to hair, improve wet and dry hair combability, especially detangling and reduced static flyaway, sheen, and fixative properties, especially curl retention, and with regard to skin and nails, improve softening or lubricating (lubricity), moisture retention and attraction (moisturizing), feel, and reduction of irritation. The dual cationic polymers may have a weight average molecular weight of from about 10 thousand to 10 million, and comprise (a) from at least 30 to as much as 75 weight percent of acrylamide (AM), (b) from at least 25 to as much as 80 weight percent of the cationic monomer dimethyldiallylammonium chloride (DMDAAC), and (c) from at least 5 to as much as 35 weight percent of a second cationic monomer of the formula: ##STR1## where Y is --O--A-- or --NH--A--, where A is ethyl or propyl; R.sup.1 is H or CH.sub.3 ; R.sup.2, R.sup.3 and R.sup.4 are independently selected from H and C.sub.1-12 alkyl; and X.sup.- is a suitable anion, especially .sup.- Cl and .sup.-OSO.sub.3 CH.sub.3.
A method of strengthening hair in need of strengthening includes the steps of applying a hair swelling component to the hair and applying a cationic polymer that is the reaction product of a lower dialkylamine (C.sub.1 -C.sub.3), a difunctional epoxy-type reactant and a third reactant selected from the group consisting of ammonia, primary amines, alkylene diamines having two to six carbon atoms and polyamines to the hair.
A hair strengthening relaxing composition comprising a cationic polyquaternary polymer that is the product of a condensation reaction of a lower dialkylamine (C.sub.1 -C.sub.3), a difunctional epoxy compound and a third reactant selected from the group consisting of ammonia, primary amines, alkylene diamines having two to six carbon atoms, and polyamines; and a high-alkalinity hair relaxing agent.
