Definitions

  • the invention relates to agents for whitening or bleaching keratin-containing fibers which contain a special combination of alkalizing agents and are free of ammonia.
  • Keratin fibers mean furs, wool, feathers and in particular human hair.
  • bleaching agents according to the invention are primarily suitable for dyeing keratin fibers, in principle there is nothing to prevent their use in other fields as well.
  • Blondierclar Lightening procedures, the so-called Blondier processor are often used as part of a cosmetic color change of the hair by the consumer.
  • the oxidizing agents contained in the bleaching agents oxidatively act on the natural hair dye melanin and, optionally, on synthetic fibers present in the fiber.
  • the coloring melanin can be almost completely decolorized oxidatively in this way.
  • the basics of the bleaching technique are known to those skilled in the art and described in relevant monographs, e.g. by K. Schrader, Basics and Formulations of Cosmetics, 2nd edition, 1989, Dr. med. Alfred Hüthig Verlag, Heidelberg, or W. Limbach (ed.), Cosmetics, 2nd edition, 1995, Georg Thieme Verlag, Stuttgart, New York, described in summary.
  • the conventional bleach ready for use keratin fibers contain hydrogen peroxide usually peroxodisulfate to increase the Aufhell Anlagen. These bleaches are usually made alkaline to achieve optimum brightening results. Most commercial products therefore have pH values of 9.0 to 11. The lightening power is optimal at this basic pH.
  • ammonia has hitherto usually been used, since ammonia-alkaline bleaching agents have better leaching than other alkaline bleaching agents.
  • the published patent application DE-A1-27 04 905 describes bleaches with ammonia-free alkalizing agent which contain a special guanidine compound to improve the lightening result.
  • the alkalization is carried out with monoethanolamine.

  • Alkaline bleaching agents that are free of ammonia can thus be formulated using short chain alkanolamines, such as monoethanolamine. While this clearly reduces the problem of ammonia odor, these amines still do not appear to be the optimal alkalizing agent.
  • high concentrations of this alkalizing agent are required.
  • higher concentrations of alkanolamines, especially in combination with hydrogen peroxide can cause scalp irritation in very sensitive individuals in some cases.

Abstract

Agents de blanchiment possédant une valeur de pH supérieure à 7, qui contiennent en tant qu'agent d'alcalisation, au lieu de l'ammoniaque, un mélange constitué d'au moins deux constituants A et B, A étant choisi parmi des dérivés spéciaux de l'imidazole et B étant au moins une alcanolamine, en particulier choisie dans le groupe formé par monoéthanolamine, monoisopropanolamine, 2-amino-2-méthyl-propanol, 2-amino-2-méthyl-1,3-propanediol, 2-amino-2-éthyl-1,3-propanediol et 2-amino-2-méthylbutanol. Lesdits agents de blanchiment possèdent un fort pouvoir de blondissement et une grande stabilité. L'utilisation de ces agents permet d'obtenir d'excellents effets éclaircissants et il n'y a pas d'effets incommodants dus à l'odeur de l'ammoniaque lors du processus de décoloration.
