Hair care compositions with diquaternary silicone polymers

The oxidation hair dye composition is made by mixing a viscous creamy hair dye-containing carrier and a fluid preparation in a weight ratio of dye-containing carrier to fluid preparation of 2:1 to 1:3. The viscous creamy hair dye-containing carrier has a viscosity of at least 10,000 mPa.s and contains 0.01 to 12 percent by weight of a combination of developer substance and coupler substance and 15 to 60 percent by weight of a thickener mixture containing fatty alcohols having from 10 to 24 carbon atoms, fatty acid esters, petrolatum, thickened polyacrylic acid derivatives, nonylphenol ethoxylated with 2 to 8 moles of ethylene oxide, fatty acids, starch and/or spermaceti. The fluid preparation contains 0.1 to 20 percent by weight of an oxidizing agent and 0.01 to 6 percent by weight of a nonionic polymer of formula (I),

Oxidative hair dyeing preparation having a content of a 1-hydroxyalkyl-2,5-diaminobenzene having the formula ##STR1## as developing substance, wherein R denotes hydroxyalkyl having 1 to 4 carbon atoms, or their salts with inorganic or organic acids. Preferably, these hair dyeing preparations will contain 1-hydroxymethyl-2,5-diaminobenzene in a concentration of approximately 0.1 to 3.0 percent by weight, this either alone as a developing substance, or in combination with the conventional coupling substances.

Agent for dyeing hair

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 monohydroxyalkyl 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, for use as an agent in a hair dyeing composition. Also disclosed are new 2-nitroaniline 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.

2-nitroaniline derivatives

A composition and process are disclosed for oxidative coloring of hair on the basis of at least one substituted phenol of the general formula ##STR1## whereby R.sub.1 represents a hydroxy alkyl group with 1 to 4 carbon atoms and R.sub.2 a hydrogen atom or alkyl group with 1 to 4 carbon atoms, or the phenolate thereof, as a coupler substance. The inventive coupler substance, of which 2-hydroxy-methyl-5-methyl-phenol and 3-(.beta.-hydroxy ethyl)-6-methyl-phenol are preferred, should be present in a concentration of about 0.01 to 3.0% by weight, in particular 0.1 to 2.0% by weight. The described coupler substances are active as blue couplers. The obtained color shades are stable, resistant to wear and very well reproducible. They have very favorable characteristics with respect to toxicology and dermatology and do not give the colored hair an unpleasant, penetrating cresolic aroma. The process involves forming an oxidizable developer-coupler combination of a developer substance with the substituted phenol as coupler substance, and an oxidation agent, applying a coloring-effective amount of the combination onto human hair, rinsing the hair after about 10-45 minutes at a temperature between 15.degree. and 50.degree. C., and drying the hair.

1,3-diamino-4-(2',2',2'-trifluoroethoxy)-benzene, as well as its acid addition salts, are used as new compounds to serve as coupler substance in hair dyeing compositions and yields with known developer substances 1,4-diaminobenzene and 2,5-diaminobenzylalcohol to stable blue tones without any red fraction. Moreover, the new compounds lead to exceptional black tones and ash tones.
