Definitions

  • the present invention relates to a process for the production of soap in the form of fine threads. To obtain products of this kind it is necessary to satisfy two conditions,
  • the process referred to one before the last is im roved on the one hand by using instead 0 soda, other desired salts or salt mixtures, for instance potash, sodium or potassium bicarbonate, potassium or sodium sulphate, potassium or sodium phosphate, potassium or sodium silicate, potassium or sodium borate, potassium or sodium acetate, potassium or sodium nitrate, the potassium or sodium salts of aromatic sulphonic a gids, such as for instance of 56b3,I1a El1 hl, lQl Sl1lph0I1lC' acids or of their homologues and substitution products or the like, which salts are referred to broadly hereinafter b the term electrolyte.
  • other desired salts or salt mixtures for instance potash, sodium or potassium bicarbonate, potassium or sodium sulphate, potassium or sodium phosphate, potassium or sodium silicate, potassium or sodium borate, potassium or sodium acetate, potassium or sodium nitrate, the potassium or sodium salts of aromatic sulphonic a
  • cold solidified soap can also be mixed with electrolytes, and in some circumstances, for instance when using pertxamim salts, is even advantageous.
  • the upper limit for the electrolytes lies approximately between 10% and 30%, the former figure holding for the case of soda and the latter for the case of other electrolytes; it naturally depends upon the fats used for the production of the soap.
  • persalts e. g. sodium perborate
  • the additional advantage is attained that by rapid cooling and pressing of the soap through fine apertures products are obtained in the form of fine threads which will keep for some time without the persalt losing any oxygen.
  • colloidal protectives are added at the same time, which envelop the persalts and thus protect them against decomposition.
  • Such substances for instance water glass are already used at the present time in the soap industry under the name protective colloids, to protect the persalts against premature decomposition.
  • the resulting mixture is converted in a manner known per se into the fine threads or fine filaments. It is more especially advisable to effect this by forcing the cold solid mass through fine mouth-pieces, in which case one can go as far as 4 mm. diameter.
  • the fundamental difierence as compared with the forcing of liquid soap through such fine apertures, referred to previously, consists in this that in this case it is not liquid but solid soap that is forced through. The soap in the present process therefore does not solidify by rapid cooling and drying after it has emerged from the nozzles, but is pressed in a cool and solid state.
  • fine apertures or mouth-pieces in the sense of this invention are only understood as being those having at most 1 mm. diameter; the use of wider apertures for pressing solid soap is not claimed for the mixture which comes into question.
  • the process described above can also be modified if desired so that the primary material used is not liquid soap, but solid soap and the aforementioned electrolyte is then added to the said soap and mixed. This is however not advisable in general, as in such a case one has not the advantage of being able to proceed immediately from soap which is still liquid, but in some circumstances conditions of manufacture may necessitate the soap being first allowed to solidify. The entire process then remains unchanged in other respects.
  • plastic masses are obtained, which solidify rapidly, and are readily pressable; products are obtained in the form of threads which no longer cake together and are immediately ready for packing.
  • the advantage consists of the addition of the above kinds of salts on the one hand in removing the adhesive character from the soaps, especially if resin is used therewith, and on the other hand they make the soaps so stiff that pressing is facilitated.
  • the electrolyte is correctly chosen, it is possible to obtain the valuable advantage that when hard water is used, the soap is protected from reacting with the lime and magnesium salts contained in the water, to form insoluble compounds. By this means considerable saving in washing material is obtained, and no damage occurs by the formation of stains and no yellowing by colloidally dispersed iron.
  • curd soap 500 kgs. 62% curd soap are mixed with a pasty mixture prepared independently and composed of 66 kgs. crystallized sodium perborate 50 kgs. water glass of specific gravity 1.35 to 1.50 and with 1 kgs. 34% soda lye. After five to ten minutes 20 kgs. calcined soda are added, again well mixed and the whole further treated as stated in Example 1 or 2.
  • the mass which is at first liquid becomes solid in the course of 5-10 minutes and can then be further treated according to Example 1 or 2.
  • What I claim is 1.
  • a process for the production of soap in the form of very fine threads, which will be rapidily soluble in cold water consisting 1n adding to soap mass so much of an alkali salt that no softening or salting-out occurs, and then converting the solid mass into threads having a diameter less than 1.5 mm. by extrusion.
  • a process for the roduction of soap in the form of very fine t reads which will be rapidly soluble in cold water, consisting in adding to soap mass in as liquid a state as possible so much of an alkali salt that no softening or salting-out occurs, and then converting the solid mass into threads having a diameter less than 1.5 mm. by extrusion.
  • a process for the production of soap in the form of very fine threads which will be rapidly soluble in cold water, consisting in adding to soap mass so much sodium perborate that no softening or salting-out occurs, and then converting the solid mass into threads having a diameter less than 1.5 mm. by extrusion.

  • a process for the production of soap in the form of very fine threads which will be rapidly soluble in cold water, consisting in adding to soap mass so much sodium perborate that no softening or salting-out occurs, together with waterglass, which prevents the decomposition of the sodium perborate, and then converting the solid mass into threads having a diameter less than 1.5 mm. by extrusion.
  • a process for the production of soap in the form of very fine threads which will be rapidly soluble in cold water, consisting in adding to soap mass so much sodium perborate that no softening or salting-out ocours, and a colloidal substance that will prevent the decomposition of the sodium perborate and then converting the solid mass into threads having a diameter less than 1.5 mm. by extrusion.
