Definitions

  • the present invention relates to cosmetic compositions for the treatment of keratin fibers and to methods and uses thereof.
  • the present invention relates to cosmetic compositions for the cleaning, conditioning, temporary or permanent shaping, fixing or coloring of keratin fibers, in particular human hair, comprising a highly branched cyclic dextrin as an anti-malodor agent, and to methods and uses thereof.
  • Keratin fibers which in the sense of the present invention are understood to mean human skin and hair, animal skin, fur, pelts, wool and/or feathers, can be tainted with bad odors, which are caused, for example, by sweat, sebum and/or fat deposits, environmental odors, diseases or cosmetic treatments.
  • the chemical components of bad odours on keratin fibres caused by sweat, sebum and/or fat deposits are predominantly short-chain fatty acids and mercaptans, which are sometimes persistent and can still be noticeable even after the application of conventional cosmetic products.
  • Bad odours on keratin fibres caused by cosmetic treatments can occur, for example, when hair is coloured or when hair is permanently shaped or fixed with products containing ammonia or thioglycolate salts.
  • perfumes or perfume compositions or deodorants are used in cosmetic products to mask or reduce bad odors on keratin fibers.
  • fragrances or fragrance molecules are subject to legal restrictions with regard to their use in cosmetic compositions.
  • a further disadvantage is that the incorporation of fragrance compositions into a cosmetic formulation matrix can cause problems, for example due to undesirable interactions with other required ingredients or due to high use amounts of additional ingredients.
  • At least one refers to one or more, i.e. 1, 2, 3, 4, 5, 6, 7, 8, 9 or more of the species mentioned. In the context of a specific species, the term does not refer to the total amount of molecules, but to the type of compound.
  • ‘at least one highly branched cyclic dextrin’ means that only one type of highly branched cyclic dextrin or several different types can be present, without specifying the amount of each individual compound.
  • Numerical ranges specified in the format "from x to y" include the specified x and y values. If multiple preferred numeric ranges are specified in this format, it is understood that any ranges created by combining the different endpoints are also included.
  • the number-average molar mass can be determined, for example, by gel permeation chromatography (GPC) according to DIN 55672:2007-08 using THF as the mobile phase.
  • the weight average molecular weight Mw can also be determined by GPC as described for Mn.
  • a cosmetic carrier is understood to be a liquid or solid carrier, depending on the form of the cosmetic product.
  • Fig. 1 is a schematic representation of a process for producing highly branched cyclic dextrin from amylose.

Abstract

La présente invention concerne des agents cosmétiques pour le traitement de fibres de kératine, qui comprennent, dans un support cosmétique, au moins une dextrine cyclique hautement ramifiée dans une proportion en poids d'au moins 0,01 % en poids par rapport au poids total de l'agent cosmétique. La présente invention concerne également un procédé de réduction ou d'élimination d'odeurs désagréables sur les fibres de kératine et l'utilisation de la dextrine cyclique hautement ramifiée dans des agents cosmétiques pour réduire ou éliminer les odeurs désagréables sur les fibres de kératine.
