252. COMPOSITIONS,

SOAPS CONTAINING ACTIVE OXYGEN AND PROCESS OF MAKING THEM.
No Drawing.
To all whom it may concern Be it known that I, ERNST Koommoonm FER, a subject of the German Emperor, and resident of Frankfort-on-the-Main, Germany, have invented certain new and useful Improvements in Soaps Containing Active Oxygen and Processes of Making Them, of which the following is a specification.
My invention relates to soaps containing oxygen and its particular object is a process for preparing especially stable soaps of this kind.'
It has been proposed before to prepare soaps containing active oxygen by admixing to an ordinary soap an alkali salt or an ammonium salt of a per-acid of boron or carbon. The soaps however prepared according to this process, contrary to what their inventor had claimed for them, have proved to be unstable, the per-salts contained in the soap being decomposed after a very short time and setting free their oxygen. Although soaps containing oxygen are badly wanted in the industry, it has nevertheless not been possible up till now to make such soaps sufficiently stable.
With the process according to my invention highly stable oxygen-soaps are obtained by mixing dehydrated soa in comminuted state, for instance soap-mgal, with compounds developing active 'oxygen, such as for instance the salts of the er-a c igl s .of boron or carhon and subjecting e mixture to a pressure high enough to generate the heat necessary to cause the particles of soap to melt down into a solid soap body. The ligating of the mass is due to the high comremn-ofine'atrwhichiscontaine(I in the powderedmixturearrd'to fire'fii'eti'qn' ogjtlie fusfig'an'd" Weldingiogether of the soap particles is facilitated by their being pressed into intimate contact with each other.
In the practice of my invention I prefer proceeding as follows: Ordina lsoap is cut or planed with a knife and the chlps of soap thus obtained are then deprived of the water contained therein as completely as possible. The dry chips are preferably reduced to a powder and this powder is then mixed with a suitable quantity of sgiilmlggbggafi which need not be deprived of its water of m'vstallizatinn. The mixture thus obtained Specification of Letters Patent.
Patented Sept. 7, 1915.
of all sorts may be made to the soap or the mixture, care being taken to avoid such substances as might set water free under pressure.
The soaps prepared according to the present invention enjoy an exceedingly great stability. Not only do they not lose their oxygen during storing, but they also keep it during use. Thus it has been ascertained that pieces of such soap contained the original percentage of active oxygen even though one half of them had been consumed by washing. Owing to its antiseptic action the soap according to my invention is suited not only for medical and cosmetic purposes, but it also lends itself with great advantage to technical application such as for instance in the washing of wool, where an antiseptic treatment of the wool was rendered till now extremely difficult on account of the inadmissibility of boiling the wool fiber. It was impossible to foretell these results. On the contrary one had reason to expect that the extremely labile carriers of oxygen would suffer decomposition under the action of high pressure generating friction and heat. The most astonish'lig fact is that the soaps obtained according to my invention give off their active oxygen during the washing process only in the proportion of soap being dissolved, the solid part of the soap retaining its content of oxygen.
In the manufacture of pieces of soap by compressing soap powder the pressure applied was kept only high enough to obtain pieces just sufliciently coherent to be handled, the cost of higher pressure being prohibitive. In the present process, on the contrary, the pressure applied should be high enough to cause the mixture of dehydrated and comminuted soap and compounds setting active oxygen free to melt down to a homogeneous mass, such pressure being far above the ordinary pressure usedfor briqueting purposes. It is further novel in this line to employ soap absolutely free of water.
W7 kzf The soaps commonly designated as being free of water are dehydrated only down to the capacity of being solidified in a press and contain at least 10 to per cent. of water (see Ubbelohdes Handbuch der Oele and Fette, Tome III, 1911, p. 937).
I claim 1. A process for preparing soap containing active oxygen which consists in mixing dehydrated and comminuted soap with compounds adapted to deliver active oxygen and subjecting the mixture to a pressure high enough to cause it to melt down to a homogeneous mass.
2. A process for preparing soap containing active oxygen which consists in mixing dehydrated and comminuted soap with a perborate and subjecting the mixture to a pressure high enough to cause it to melt down to a homogeneous mass.
3. As a new composition of matter a fused and substantially anhydrous mixture of soap and compounds containing active oxygen and characterized by its exceedingly great stability.
4. As a new composition of matter a fused and substantially anhydrous mixture of soap and a perborate, possessing very great stability.
In testimony whereof I have signed my name to this specification in the presence of two subscribin witnesses.
