Definitions

  • the invention is in the field of cosmetics and relates to cosmetic, non-therapeutic compositions containing fatty acid soaps and suitable microemulsions.
  • Cosmetic cleansers usually contain surfactants and / or surfactant combinations which, because of their irritant effect, can exert a negative influence on the skin flora and are therefore not recommended for use on unclean skin and / or acne-infested skin.
  • the alkaline pH can also exert a negative influence on the skin, which can worsen skin texture especially in skin irregularities.
  • alkaline soaps lead to a strong degreasing of the skin.
  • milder compositions are desirable, not only selectively at the site of application (the skin) growth and / or survivability of saprophyte germs of the skin flora over the Promote growth and / or survival of pathogenic bacteria of the skin flora, but in particular to ensure a gentle skin cleansing and excellent care of the skin.
  • the skin adhering additives with moisturizing properties such as fatty acid esters, especially triglycerides or waxes suitable.
  • moisturizing properties such as fatty acid esters, especially triglycerides or waxes suitable.
  • a disadvantage of the use of these nourishing additives is that these substances generally can not be incorporated clearly into transparent soaps.
  • silicones-containing bar soaps often have the disadvantage that, with regular use over a longer period of time, they lead to a sensation of being perceived as unpleasant by the consumer.
  • oils and waxes in bar soaps are not as pronounced as that of silicones.
  • oils and waxes can be stabilized in smaller quantities in bar soaps, which makes it difficult to produce such agents.
  • bar soaps with higher amounts of oils and waxes are difficult to produce as transparent bar soaps.
  • energy-intensive process steps must be carried out, or additional synthetic stabilizers must be incorporated into the bar so that the preparation of the agents is disadvantageous from an economic and ecological point of view.
  • the bar soaps should contain higher amounts of at least one nourishing, moisturizing and conditioning lipid component, without the stabilization of the lipid component in the bar soaps necessitating additional and energetically elaborate steps such as heating, melting or predispersing. Likewise, the incorporation of polymeric or crystalline agents for stabilizing the lipid component should be dispensed with. Finally, the bar soaps should preferably be transparent, wherein high amounts of polyols can be dispensed with.
  • Another object of the present invention was therefore to find substances or substance mixtures which have moisturizing, conditioning and nourishing properties on the skin, show good adhesion to the skin surface and with which transparent soap bars can be produced.
  • surfactant liquid detergents have recently used microemulsions of the lipids as nourishing, replenishing and conditioning lipid components.
  • surfactant cleaners In contrast to bar soaps, liquid, surfactant cleaners have a significantly lower pH range. Such agents usually have a pH of 4 to 6.
  • Another significant difference between bar soaps and surfactant liquid cleaners is the content of the aqueous phase.
  • Liquid surface-active agents here have a content of usually 75 to 95 wt.% Of water.
