Definitions

  • the invention relates to a shaped Syndet soap composition with a content of at least 50% by weight of synthetic surfactants and at least 10% by weight of non-surfactant Auxiliary materials.
  • Alkyl (oligo) glycosides are components in bar soaps based on fatty acid soap already described several times, e.g. in DE-A-43 37 031 and in DE-A-43 31 297. Their use in soap compositions based on alkyl sulfates and sulfosuccinate salts is from G. Proserpio and G. Vianello in Rivista Italiana Essenze Profumi ... (1974), No. 10, page 571 has been described.
  • DE-A-4 409 321 relates to detergent mixtures containing 70 to 95% by weight of fatty acid isethionate salts contain and their workability is improved by adding fatty alcohols.
  • Acyl isethionates have long been known skin-friendly surface-active substances which can be obtained by esterifying fatty acids with the sodium salt of 2-hydroxyethanesulfonic acid (isethionic acid), for example by the process described in US Pat. No. 3,320,292. If fatty acids with 12 to 18 carbon atoms, for example lauric, myristic, palmitic or stearic acid or technical fatty acid fractions, for example the C 12 -C 18 fatty acid fraction obtainable from coconut fatty acid, are used for this esterification, the suitable ones according to the invention are obtained C 12 -C 18 acyl isethionates.
  • Alkyl (oligo) glycosides (B) their preparation and use as surfactants for example from US-A-3,839,318, US-A-3,707,535, US-A-3,547,828, DE-A-19 43 689, DE-A-20 36 472, DE-A-30 01 064 and EP-A-77 167 are known.
  • the Degree of oligomerization is a static mean, one for such technical Products based on the usual homolog distribution. (The average degree of oligomerization results from the molar proportions of the individual oligomers by dividing the Sum of the structural units by the sum of the molecules).
  • R is particularly preferably an alkyl group having 8 to 16 carbon atoms, which is derived from a C 8 -C 16 fatty alcohol fraction.
  • the syndet soap composition according to the invention is preferably free of fatty acid soaps, Amounts of less than 10% by weight of fatty acids in the form of soaps can be tolerated become.
  • the content of alkyl sulfates should also be below 10% by weight if possible.
  • Syndet soap compositions according to the invention can also be used in minor amounts in the Syndet soap compositions according to the invention contained, but its proportion should be less than 10 wt .-% of the syndet mass stay.
  • the free, saturated linear are preferably suitable as non-surfactant auxiliaries
  • Fatty acids with 12 - 22 carbon atoms as e.g. in the form of hardened coconut or Palm kernel fatty acid or hardened tallow fatty acid or hardened rapeseed oil fatty acid are present.
  • Such free fatty acids are preferred in the Syndet soap compositions according to the invention in Contain amounts of 10 to 30 wt .-%.
  • the production of the shaped Syndet soap compositions according to the invention can be carried out in the such products are carried out in the usual way, the combination of synthetic surfactants a particularly well formable, plastic in the heat and after hard mass results on cooling.
  • the molded products have a smooth surface that dries again after wetting with water without softening.
  • meltable components for example the fatty acid, the fatty alcohol, the alkyl (oligo) glucoside and, if appropriate, meltable or liquid fillers and auxiliaries are melted and mixed at a temperature in the range from 60 to 90 ° C. in a heatable kneader or mixer .
  • the C 12 -C 18 -acyl isethionate salt, optionally the sulfosuccinate and other components which cannot be melted at 60 - 90 ° C and possibly the water, are added, and the batch is mixed or kneaded at a temperature of approx. 70 ° C.
  • a further homogenization can be achieved in that the mass passes through several times Sieves pressed and finally at a head temperature of 40 to 70 ° C to a strand is pressed, which is cut into uniform pieces.
  • the pieces can be shootable are brought into the final shape in a molding press.
  • extrusion through a perforated plate can also take place noodles or needles are obtained or if the perforated plate is followed by a knife are formed, granules.
  • the Syndet soaps were produced in a heatable kneader.
  • the Components were heated to 90 ° C and mixed intensively.
