Definitions

  • the present invention relates to cosmetic cleansers in the form of shaped soap products. Such agents are known per se. It is essentially about surface-active substances or mixtures of substances which are available to the consumer in various Preparations are offered.
  • the invention particularly relates to bar soaps with improved Smoothness and increased lime soap dispersibility due to a content of talc and one or more amphoteric surfactants in the simultaneous absence of alkyl (oligo) glycosides.
  • Skin-specific surface-active substances also make skin fats to a certain extent solved and washed out. This requires a subsequent swelling after a subsequent Significant dehydration of the skin, which are reinforced by detergent additives can.
  • Main components are the alkali salts of the fatty acids of natural oils u. Fats, preferably the chain lengths C 12 -C 18 . Since lauric acid soaps foam particularly well, the lauric acid-rich coconut and palm kernel oils are preferred raw materials for the production of fine soap.
  • the sodium salts of the fatty acid mixtures are solid, the potassium salts soft-pasty.
  • saponification the diluted sodium or potassium hydroxide solution is added to the fatty raw materials in a stoichiometric ratio so that an excess of alkali of not more than 0.05% is present in the finished soap. In many cases, the soaps are no longer produced directly from the fats, but from the fatty acids obtained by lipolysis.
  • Surfactants are amphiphilic substances that can dissolve organic, nonpolar substances in water. They provide, due to their specific molecular structure with at least one hydrophilic and a hydrophobic part of the molecule, for a lowering of the surface tension water, wetting the skin, facilitating the removal of dirt and solution, a light rinse and, as desired, foam control.
  • Non-ionic surfactants are polyether chains.
  • Nonionic surfactants form in aqueous medium no ions.
  • the foam also gets a better creaminess and more volume, which also was not expected.
  • Another advantage of this invention is that the compatibility of the washing piece is improved because the total content of surface-active substances is reduced becomes.
  • the molded soap products according to the invention also possess the mechanical properties Deformation a particularly smooth surface. At the application they produce a creamy, stable foam. The lime soap precipitate formed in hard water remains dispersed in the water and does not lead to the gray-greasy deposits on the surface of sanitary objects.
