Definitions

  • the well-known soap powders comprising compounds containing active oxygen, more particularly containing persalts, are made by mixing dry finely powdered soap and, ersalts in the form of powder with or wit out addition of other dry washing agents in powder form.
  • the size of the granules as well as the specific weight of the constituents are different.
  • the soap in powder-form dissolves quicker than the persalt when they are employed and there is thus the danger that the 5 less soluble persalts of greater specific weight settle upon the articles being washed, and, forming a concentrated solution, cause a strong local action and thus a damage to the materials.
  • soap containing soap is used for the manufacture of soap flakes or soap bands containing persalts.
  • the soap with a relatively low water content, for instance from 8 to 14% water, are exceedingly brittle when used alone. It appeared to us that it would not be possible to form the soap into thin flakes or the like when adding persalts to the soap.
  • the form of thin flakes or the like is of as it ensures a uniform solution of the soap and of the persalts contained therein. In this form it is not possible for perborate granules liberated from the soap envelope to produce a strongly concentrated local bleaching solution which would cause holes to be formed in the articlesbeing washed.
  • soap hav--- ing a small water content say from 8 to 14% water
  • soap hav--- ing a small water content say from 8 to 14% water
  • compounds in powder form, containing active oxygen, particularly persalts the mixture is then rolled out thin in rolling machines and cut up in a cutting machine into small pieces in flake form.
  • the essential feature of the present process consists in mixing soap having a small water content and persalts, and bringing these mixtures into a form which with certainty prevents the constituents becoming dissociated, which would cause damage to the may be made,
  • the soap thus produced is dried, mixed with 20% sodium perborate and rolled in chine. Translucent flakes which are readily soluble, even in cold water.
  • this soap is dried and mixed with 15% sodium perborate. After chine translucent,
  • selection of the acid to be added depends on the kind and quantity of the combined salts containing active oxygen particularly persalts or mixtures of salts containing active oxygen particularly persalts.
  • Another modification in the manufacture of translucent flakes or bands from a mixture of soap having a. small water content and containing salts giving off oxygen consists in adding to the mixture hydrocarbons having the formula C H and C,,H with at least ten carbon atoms or their oxy-compounds, free or in the form of their esters. More strongly unsaturated hydrocarbons, for instance those having the formula C H are not suitable, as they do not obviate the danger of the decomposition of the compounds which give ofl' oxygen. In this case only the acids mentioned above are suitable.
  • EanzmpZe 1 To a mixture of a soap having 84% fatty acid and sodium perborate the cetyl ester of palmitic acid is added, for instance 4%, and after the said ester has been mixed with the mixture of soap and compounds containing oxygen the mixture thus obtained is passed through a rolling machine, the lower roll of which is heated. Bands of good translucence are obtained.
  • Ewample 2 To the mixture of dried soap and oxygen-containing compounds is added for instance 5% of readily oxydized paraflin which by treatment with alkali is freed from the free fatty acid formed, the ingredients are mixed and the entire mixture is passed through the rolling machine. Smooth translucent flakes are obtained after the bands have been suitably divided.
  • the oxydized para-fiin may however be previously added to the water-containing soap. In that case the soa is first dried and worked up to ether wit the oxygen-containing compoun into flakes.
  • a third modification of the manufacture of translucent flakes or bands from soap mixed with salts consists in using for the manufacture of the soaps fatty acids which are partially converted into potassium salts, so that the soap which has a small water content or has been dried there will constitute a mixture of potash and soda soaps. If this mixture consisting of potash-soda soaps be mixed with salts which give oflt' oxygen, translucent and sufliciently elastic products may be made. The following is an example of the manufacture of such a soap:
  • a soap mixture is made containing 17% potash soaps and 83% soda soa s and the mixture is dried. To 80 parts 0 this dried soa mixture for instance 20 parts of sodium .per orate are used and these raw materials are then intimately mixed together. A mixture of potash-soda soaps is thus obtained with the addition of sodium perborate, which is passed through the rolling machine, and leaves it in the form of a smooth, elastic and translucent band, which may readily be cut up into elastic and translucent flakes.
  • This modification is not restricted to the limits of 17 potash soaps and 83% soda soaps given in the above example and also not to the. proportions of the soap mixture with the salts there given.
  • the mixtures of salts may be used in place of the salt and the ercentage of potash soaps may vary accor ing to the kind and quantity of the added salt.
  • the proportions of the soap mixture of potash and soda soaps will be chosen according to the kind and quantity of the added salt or mixtures of salts used.
  • the main idea underlying the present invention consists in this, that for making soaps into a stable mixture with salts giving off oxygen soap having a water content of less than 15% has for the first time been used. Hitherto it has been assumed that the soap should be completely dry, in order to prevent the destruction of the persalts; it had not however been found possible to make bands or flakes from the dry soap combined with the persalts. For the same reason it had been found still more diflicult to make translucent flakes or bands, such as can be made according to the present invention, even with completely dried soap.
  • This cutting device comprises a steel roller a, Fig. 1, which runs on the last roller 1) of the rolling machine, and contains two cutting devices, Figs. 2 and 3, with which the sheet of soap lying on the last roller can be divided both longitudinally of the direction of travel and transversely of the same.
  • the sheet is divided transversely by the cutting roller being provided with spirals 0. These cutting spirals have a greater or smaller distance from one another, according to the dimensions to which the soa flakes are to be cut.
  • the separation of the soap flakes in the longitudinal direction is effected by the cutdivided into a plurality of parts and a thln, round, steel disc d being between each two such parts, which effects the longitudinal cutting.
  • the size of the parts, into which the cutting roller is divided, and the number of steel discs depends on the desired dimensions of the soap flakes. If, for instance, the soap flakes are to be 10 mm. wide, the parts of the roller are also made 10 mm. wide and between each two such parts there is a steel cutting disc.
  • the spirals and the separate steel discs By varying the spirals and the separate steel discs, it becomes possible to make any shape of flake, for instance rectangular, rhomboidal or triangular flakes, by means of a single cutting device.
  • the discs and the spiral roller parts and consequently the shapes to be made can be varied in a very simple manner by making the discs readily removable by the usual means for fixing such parts on an ordinary roller by folds, grooves, an angular shaped core to the roller, and the like.
  • the central feature of the apparatus according to the present invention which is closely associated with the manufacture of the flakes or bands, that is the new process claimed herein, consists in effecting by means of a single cutting device in a single operation a transverse and longitudinal division of the sheet of soap consisting of a mixture of soap and persalts cutting through the said sheet of soap and considerably reducing the time taken by the operation, so as to prevent an unnecessary over-heating of the raw materials and the consequent possibility of the destruction of the admixed persalts.
  • Per carbonates may be used in a way analogous to the described use of perborates.
  • a process for the manufacture of soap ting roller being flakes which comprises forming soap; containing Water but less than 15% thereof, incorporating with said soap a peralkaline salt and forming said mixture into thin flakes.
  • a process for the manufacture of soap flakes which comprises forming a soap containing a moisture content of approximately 8 to 14%, incorporating with said soap a peralkaline salt and forming said mixture into thin flakes.
  • a process for the manufacture of soap flakes which comprises forming soap containing water but less than 15% thereof, incorporating with said soap a per-alkaline salt and a hydrocarbon of the C H type containing more than 9 carbon atoms and forming the soap into flakes.
  • An article of manufacture comprising soap flakes containing water 'but less than 15% thereof and a per-alkaline salt.
  • An article of manufacture comprising soa flakes containing approximately 8 to 14% water and a per-alkaline salt.
  • An article of manufacture comprising soap flakes containing water but less than 15% thereof, a per-alkaline salt and a hydrocarbon of the C H type having more than 9 carbon atoms.
  • a process for the manufacture of soap flakes which comprises forming a soap containing a moisture content of not over 8% incorporating with said soap an alkali metal salt of a peracid having bleaching properties and forming said mixture into thin flakes.
  • An article of manufacture comprising soa-p flakes containing not over 8% Water and an alkaline metal salt of a peracid having bleaching properties.
  • An article of manufacture consisting of soap flakes forming as a whole a loose, noncoherent mass, each flake of which contains water in amount less than 15%, a per-salt of an alkali metal, and a hydrocarbon of the C H type where n has a value greater than 9, all thoroughly and intimately commingled.
