The skin and hair treatment composition includes 0.5 to 2 percent by weight apple wax, 0.1 to 30 percent by weight of at least one anionic, cationic, amphoteric and/or nonionic surfactant, a solvent consisting of water, ethanol, propanol, isopropanol, glycols or mixtures thereof and one or more cosmetic additives selected from the group consisting of perfume oils; opacifiers; pearlescing agents; bacterial and fungicidal ingredients; coconut fatty acid diethanolamide; buffer substances; coloring materials; solubilizers; light stabilizers; antioxidants; complexing agents and antidandruff active ingredients. Methods for obtaining the apple wax used in these compositions include extraction of depectinized apple pomace with a variety of solvents and purification and evaporation of the extract to obtain an apple wax product.

A composition for dyeing hair containing 2,5-diamino-6-nitropyridine, a solvent which is preferably water, a surfactant and at least one cosmetic additive selected from the group consisting of thickeners; care agents; perfume oils; complexing agents; oxidation hair dyes; and direct hair dyes; preservatives; a pH-adjusting member selected from the group consisting of ammonia, monoethanol amine and triethanol amine; and a polymer selected from the group consisting of chitosan derivatives, polyvinyl alcohol, polyacrylic acid, polymethacrylic acid, polyacrylonitrile, polyvinyl lactam and copolymers thereof.

Hair dye compositions based on 2,5-diamino-6-nitropyridine derivatives

The composition for dyeing hair yellow contains 2-nitroaniline derivatives of the general formula I: ##STR1## in which, R.sup.1 and R.sup.2 represent, independent of one another, hydrogen an alkyl of 1 to 4 carbon atoms, a monohydroxyallkyl of 2 to 4 carbon atoms or a dihydroxyalkyl of 3 or 4 carbon atoms, provided that R.sup.1 and R.sup.2 do not simultaneously represent alkyl groups of 1 to 4 carbon atoms, and X denotes an alkyl, monohydroxyalkyl, perfluoroalkyl or halogen. Also disclosed are new 2-nitroanitrile derivatives of the general formula II: ##STR2## in which R.sup.a and R.sup.b denote, independent of one another, ethyl, a monohydroxylalkyl of 2 to 4 carbon atoms or a dihydroxyalkyl of 3 or 4 carbon atoms, when Z is methyl, Cl or Br; or when Z is CH.sub.2 OH or a perfluoroalkyl, R.sup.a denotes hydrogen, a monohydroxyalkyl of 2 to 4 carbon atoms or a dihydroxyalkyl of 3 or 4 carbon atoms, and R.sup.b represents 2-hydroxyethyl or 2,3-dihydroxypropyl.

The quaternary chitosan derivatives useful in cosmetic compositions are made by a process comprising reacting a chitosan consisting of 50 to 100% deacetylized chitin or a structurally modified chitosan made by reprecipitating and deep freezing, with glycidyl trialkyl ammonium halogenide, particularly glycidyl trimethyl ammonium chloride, and, if necessary, with glycidol. The reaction mixture is advantageously stirred for several hours at 10.degree. to 100.degree. C. The reaction may be performed in the presence of an organic or inorganic acid or base in water.

Tetrafluoroethoxybenzenes, and their acid addition salts, of the general formula: ##STR1## in which R.sup.1 may represent hydrogen or an alkyl having from 1 to 4 carbon atoms and R.sup.2, R.sup.3 and R.sup.4 represent one or more of the same or different substituents selected from hydrogen, an alkyl having 1 to 4 carbon atoms or mono- or dihydroxyalkyls having 1 to 4 carbon atoms, provided that the amino groups are situated relative to one another in an ortho- or meta- position and R.sup.1, R.sup.2, R.sup.3 and R.sup.4 do not simultaneously represent hydrogen when the amino groups are arranged in a 2,4-position. The compounds of the invention, along with 2,4-diaminotetrafluoroethoxybenzene, are useful as coupler components in oxidative hair coloring agents. A process for making the compounds, as well as a separate process for making the mono-N-.beta.-hydroxyethyl compounds, is provided.
