  • Cosmetic cleaners such as hair shampoos, shower baths or bath preparations, are based on conventional anionic, amphoteric, zwitterionic, nonionic and / or cationic surfactants.
  • anionic surfactants if appropriate in the mixture with small amounts of co-surfactants, are used in conventional cleaning agents.
  • Surfactants soften the skin during the cleaning process and remove lipids from the outer skin layers. As a result, the skin - especially in the case of very frequent cleaning with commercially available cleaning agents - dry, brittle and sometimes cracked, unless it is fed back after or during cleaning lipids in the form of creams and / or lotions.
  • rinse-off body lotions often make it difficult to rinse off the skin and require a high water consumption.
  • rinse-off shower creams do not always have satisfactory care properties and rinse-off shower oils are rejected by many consumers because of their low foaming power.
