Abstract: The treatment of proteinaceous or other substrates to render them more manageable and more stable against chemical treatment involves the use of aqueous compositions containing cationic (meth)acrylic copolymers.

Abstract: A composition for lightening or coloring hair comprising a liquid vehicle, an oxidizing agent and at least one di-long chain aliphatic hydrocarbon quaternary amine compound and a method for lightening or coloring hair using this composition.

Abstract: An autoxidizable hair dye preparation is disclosed capable of coloring or darkening hair when applied thereto and exposed to the atmosphere comprising a mixture of (I) at least one p-phenylene diamine compound, or an acid addition salt thereof, and (II) at least one 1,2,4-benzenetriol compound, each compound optionally containing nuclearly substituted C.sub.1-4 alkyl, alkoxy, hydroxyalkyl or halogen. The preparation is preferably applied and exposed to the atmosphere repeatedly until the desired degree of darkening or color build-up is attained.

Abstract: A hair conditioning composition relatively stable toward repeated shampooings comprising an aqueous acidic composition containing a cationic polymer product, an amphoteric surfactant product and a betaine and a process for treating hair, particularly hair containing an alkaline residue from prior hair treating processes, with the same.

Abstract: An autoxidizable hair preparation capable of coloring hair when applied thereto and exposed to the atmosphere comprising N,N-bis(2-hydroxyethyl)-p-phenylenediamine or an acid addition salt thereof and a triol selected from the group consisting of 1,2,4-benzenetriol and 2,4,5-trihydroxytoluene. The preparation is applied at multiple spaced intervals of time until the desired color build-up is attained. Also prepares the composition by preforming a solution of the triol by storing the corresponding triacetate in acid solution for a period of time then adding the N,N-bis(2-hydroxyethyl)-p-phenylenediamine.

Abstract: An aqueous alkaline hair dye composition containing N.sup.1,N.sup.4,N.sup.4 -tris(2' -hydroxyethyl)-2-nitro-p-phenylenediamine and a particular class of aminohydroxy compounds as alkalizing agent. The aminohydroxy compound is defined as follows: ##EQU1## wherein: A. R.sup.1 and R.sup.2 are hydrogen, hydroxyethyl or hydroxyisopropyl;B. R.sup.3 and R.sup.4 are hydrogen, lower alkyl having 1 to 3 carbons and lower monohydroxyalkyl having 1 to 3 carbons; providing that both R.sup.3 and R.sup.4 are hydrogen only when either R.sup.1 or R.sup.2 is hydroxyethyl or hydroxyisopropyl;C. R.sup.5 is hydrogen or methyl.Examples of suitable aminohydroxy compounds are diethanolamine; triethanolamine; 2-amino-2-methyl-1-propanol; tris(hydroxymethyl)aminomethane; 2-amino-2-methyl-1,3-propanediol; diisopropanolamine; triisopropanolamine.

Abstract: A semi-permanent hair dye composition that simultaneously dyes and conditions hair to make it more manageable including a direct dyeing nitro dye capable of dyeing hair, certain quaternary amine compounds and certain N-oxyalkylated fatty acid amides.
