Definitions

  • the present application relates to a method for filling hair color-changing products in packaging, wherein on the already filled preparation, a preparation containing a reducing agent is sprayed, and the use of such reducing agent-containing solutions to prevent changes in hair color-changing agents during storage.
  • Human hair is treated today in many ways with hair cosmetic preparations. These include, for example, the cleansing of hair with shampoos, the care and regeneration with rinses and cures and the bleaching, dyeing and shaping of the hair with dyes, tinting agents, waving agents and styling preparations. In this case, means for changing or nuancing the color of the head hair play a prominent role.
  • dyeing or tinting agents which contain as coloring component so-called substantive dyes. These are dye molecules that attach directly to the hair and do not require an oxidative process to form the paint. These dyes include, for example, the henna already known from antiquity for coloring body and hair. These dyes are usually sensitive to shampooing, so that sometimes an undesirable shift in shade or even a visible “discoloration" occurs.
  • oxidation colorants For permanent, intensive dyeings with corresponding fastness properties, so-called oxidation colorants are used. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components. The developer components form under the influence of oxidizing agents or of atmospheric oxygen with one another or with coupling with one or more coupler components, the actual dyes.
  • the oxidation stains are characterized by excellent, long lasting staining results.
  • a mixture of a larger number of oxidation dye precursors must usually be used; In many cases, direct dyes are still used for shading.
  • dye precursors are respectively applied to the hair, from which the actual dyes develop by oxidation. Since the dye precursors used are therefore highly sensitive to oxidation, there are regularly problems with the filling and storage of these components.

Abstract

La présente demande porte sur un procédé de conditionnement d'agents modifiant la couleur des cheveux dans des emballages, selon lequel dans une première étape, la préparation modifiant la couleur des cheveux est introduite dans l'emballage et dans une deuxième étape, une autre préparation contenant au moins un réducteur est appliquée à la surface de la préparation modifiant la couleur des cheveux, alors que dans une troisième étape, l'emballage est fermé. A l'aide de ce procédé, il est désormais possible de réduire l'altération de la couleur du produit colorant pendant le stockage, ce qui induit parfois à des réclamations, ou de d'éviter entièrement ce phénomène d'altération de la couleur.
