Definitions

  • the invention relates to new bar soaps which contain selected sugar surfactants, partial glycerides and fatty acid salts as essential components.
  • Modern bar soaps especially toilet or fine soaps, are usually based on mixtures of beef tallow and coconut oil in a ratio of about 9: 1.
  • This fat deposit is hydrolyzed by adding sodium hydroxide solution to the basic soap, which contains other additives such as. B. humectants, fillers and binders, superfatting agents, dyes and perfumes etc. are added.
  • Usual fine soaps contain about 80% fatty acid salts, 10% water and ad 100% auxiliaries and additives.
  • the large number of products offered to consumers document the lively market interest and nevertheless make it clear that consumers have a constant need for further improved products, which, in particular due to improved stabilities, also have good dermatological compatibility, greater foaming power and higher creaminess , Rinse and skin feel. Soap manufacturers, on the other hand, are looking for soap formulations that, for example, lead to pieces with higher breaking strength or allow the easy incorporation of certain surfactants.
  • bar soaps are desired that have a higher stability compared to the prior art and allow the incorporation of new oil bodies. Furthermore, these soaps are also said to produce a comparatively productive and creamy foam, convey a good feeling on the skin and have a lower tendency to swamp and cracking.
  • the object of the present invention was therefore to provide bar soaps of the complex requirement profile described.
  • the invention relates to bar soaps containing
  • sugar surfactants selected from the group formed by (a1) alkyl and / or alkenyl oligoglycosides and / or (a2) fatty acid N-alkylpolyhydroxyalkylamides,
  • bar soaps can be produced from selected sugar surfactants in combination with partial glycerides which are stable over a longer period of time. It is particularly surprising that there is no hydrolysis of the partial glyceride, for example glycerol monooleate, at an alkaline pH or that the hydrolysis has no influence on the stability of the bar soap. Another advantage is the stable and creamy foam, an increased water retention capacity on the skin (skin moisture) and a further reduced tendency to swamp. The consistency of these formulations corresponds to recipes customary on the market.
