PROCESS OI MAKING OXYGEN-CONTAINING SOAP POWDERS.

No Drawing.

To all whom it may concern:

Be it known that I, REINHOLD Konsnm, citizen of the German Republic, residing at Zittau, Saxony, Germany, have invented certain new and useful Improvements in Processes of Making Oxygen-Containing Soap Powders, of which the following is a specification.

This invention relates to a novel process of making oxygemcontaining soap-powders and similar admixtures for washing and! bathing waters and consists essentially therein that by the admixture of a catalyzer into paste-like or liquid soap an air-dry catalyzer mixture is produced which is mixed with the carrier of the oxygen, where by said catalyzer may furthermore be finely pulverized and calcined carbonate of soda be added until a dry powder is obtained, and a proper granulation produced for mixing the same with the carrier of the oxygen.

It is known to use oxygen for washing and bathing waters, whereby a carrier of oxygen and a catalyzer is employed. This invention has for its object to distribute the discharging of the oxygen uniformly over a period of time, which ma be predetermined. In the known mixtures t e constituents will separate after being introduced into water; by this they will at once be caused to dissolve thus being exposed to a mutual action upon each other. The discharging of the catalyzer, however, will only take place in accordance with the slow solubility of soapparticles, so that an exhaustive discharge of the oxygen for washing water may take place, for instance, during ten and for bathing waters during thirty minutes. An im portant feature of this invention consists therein, that the catalyzer is embedded in a paste of soap. The discharging of the oxygen or the action of the catalyzer upon the oxygen will take place regarding quantity and time of discharge in accordance with the process of the dissolution of the soap globules. The latter may be sifted during the process of the mixture in greater or smaller sizes. According to this the duration of the dissolution of the several globules of soap and catalyzer mixture and therewith the respective duration of the action or distribution of the generation of oxygen Will be determined. With the resent process also the stability of the pro uct during storage will be completely attained, because the Application filed April 9, 1924. Serial No. 705,394.

product consists of a dry mixture and the catalyzer is embedded.

As an example of the manufacture of soap powders according to this invention the following may serve. 1.5 gr. of permanganate of potassium are finely ground into pulverized form in a grinding bowl and 5 gr. neutral soap, which in the meanwhile has been brought to paste-consistency by heating the same with some water in well mixed with the same after coolin off.

In order to secure a quick drying, when this is desired such a quantity of calcined carbonate of soda is gradually added into the ground matter, that a gray dry powder is obtained. Thereupon the catalyzer, mixture is mixed-not by grinding but pref erably by the aid of a mixing machinewith such a quantity of calcined carbonate of soda, that in the whole 773.5 gr. will come to application.

After. proper granulation, on the next day the perborate is added by intimate mixing and the packing is done at once.

This composition would correspond to a skin-washing lotion for daily use or for medical purposes or for a cold rub-down, whereby the oxygen will discharge in a time which is-proper for these purposes, that is in about 5 to 8 minutes. The use of warm water will correspondingly abbreviate the time of the discharge of the oxygen.

If the soap according to this invention shall be applied for the purpose of baths, whereby in most cases warm water is applied, about one third of the above-mentioned quantity of permanganate of potassium would appear suflicient. For baths of a duration of 15 to 20 minutes the dose for skin-washing purposes would also sufiice, if the bathing person will add the intended quiisntity during bathing in certain interva Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States:

1. The process of making oxygen-containing soap powders and similar admixtures for washing and bathing waters, which consists in mixing we: with paste-like soap, and mixing the same with an oxidizing agent.

2. Process of making oxygen-containing soap powders and similar admixtures for washing and bathing waters, which confor washing and bathing, which consists in well mixing finely pulverized otassium ermanganate with paste-like ngujraLsnap, adding calcined sodium carbonate to the mixture until a dry powder and a proper granulation results, and mixing said powder with a perborate.
