  • Patent number: 4297098
    Abstract: Living human hair is progressively colored to the desired light brown shade by repeated applications of a preparation containing a low concentration of a mixture of oxidative dye components, namely, 2 to 3 components selected from p-phenylenediamine (or p-toluenediamine), pyrogallol, and m-aminophenol. To obtain a gradual, true color development, it is important to employ the dye components in certain relative proportions. In the use of the preparation, no oxidizing agent is added, and the color development reaction is obtained by contact of the dye mixture with atmospheric oxygen. The preparation is preferably in the form of an aqueous gel also containing hair grooming or conditioning agents.

  • Patent number: 4121904
    Abstract: Depilatory compositions for removing hair from live human skin on the human body, said compositions containing, as essential ingredients, water; sodium thioglycolate and calcium thioglycolate, said thioglycolates representing the sole or essentially the sole depilating agents; a water-soluble soap, particularly sodium stearate, which is advantageously formed in situ by reaction of sodium hydroxide and a soap-forming aliphatic monocarboxylic acid, and ingredients which comprise a vehicle in the form of a cream or paste.

  • Patent number: 4061150
    Abstract: This invention is concerned with the pretreatment of hair on the human head, preceding shampooing the hair with anionic type hair shampoos, and with compositions for effecting such pretreatment, to obtain highly improved manageability of the hair after shampooing and with improved fullness, compability and other desired properties of the hair. The pretreatment compositions utilize readily water-soluble quaternary ammonium compounds, particularly in combination with certain agents, notably polyethylenimines and N-ethanolacetamide, and desirably together with various supplemental ingredients.
