Definitions

  • the invention relates to fatty acid-free syndet soaps containing alkyl and / or alkenyloglycosides and starches
  • Stucco soaps play a major role in body cleansing, which are now produced on an industrial scale by continuous saponification of free fatty acids with alkalis, concentration of basic soaps and spray drying.
  • the so-called" syndetbars " have a special status. They are free of fatty acid salts except for impurities and contain only synthetic surfactants
  • alkyl glucosides have become increasingly important as new nonionic surfactants, because they behave like anionic surfactants in many ways, for example in their foaming power, and at the same time have an extraordinarily high ecological and dermatological compatibility. It was therefore obvious to deal with such surfactants also in connection with bar soaps.
  • toilet soaps are known from European Patent EP-B1 0 463 912 (Colgate) which contain 1 to 20% by weight of alkyl polygiucosides and preferably 55 to 66% by weight of soap as a framework substance.
  • the object of the invention was therefore to provide bar soaps that are free from the disadvantages described. It was particularly important to take into account that new bar soap compositions must also be able to be manufactured on an industrial scale, i.e. that the compositions have, for example, sufficient but not too high deformability and do not tend to crack during drying.
  • the invention relates to syndet soaps containing
