SUBSTITUTE FOR SOAP FOR WASHING, CLEANING, AND BLEACHING PURPOSES.

No Drawing.

Be it known that I, Pxt'l, lLtLsom-r, a citizen of the United States of America, residing at Frankfort-on-the-liain. Germany, have invented certain new and useful improvements in Substitutes for Soap for Specification of Letters Patent.

Application filed January 18, 1908.

. water, at which time the caustic soda is bound This invention relates to a new and useful 1 ct'miposition of matter adapted tor washing t even then the safe use of sodium peroxtd and cleaning purposes and has as its object a harmless mixture which will give ofl' active oxygen when dissolved in water, while atv the same time it will not. prove harmful to the fiber or color of textiles or other organic substances.

There have been known and recommended for washing purposes substances which give ofi' active oxygen when in use. like sodium peroxid, permanganate of potash or liquid hydrogen peroxid. However, it is a well known fact that liquid hydrogen peroxid requires breakable glass packages and also involves a very high cost of transportation through the large quantity of useless liquid carried along with its oxygen. It is likely to be quickly damaged or altogether spoiled by unfavorable weather and climatic influences, and it ditlicultor altogether impossible to bring it before the consumer economically in the necessary small quantities. The use of hydrogen peroxid for such purposes has, therefore, been insignificant. As another oxidizing substance sodium peroxid has been proposed for this use, but it is nota product that can be safely given into the hands of the general public on account of its liability to inflame organic substances. Furthermore, when dissolved in water it forms caustic soda and makes such a strong alkaline bath, that it is sure to have some serious effect upon the fiber of the material with which it is used or upon the hands of the person using it. Italso has too strong an influence upon the color of textiles, etc., owing to its extreme alkalinity. To overcome these diflicult-ies it has been proposed to use sodium peroxid in direct mixture with cer- 1 tain substances forming a non-objectionable and soluble salt with the oausticsoda which results when sodium peroxid is dissolved in water. This has p'iovifimpracticable because t-he salts mixed with the sodium peroxid with the acid of the salts. But this expedient requires the most careful packing and cannot be guaranteed for the general public.

lernianganatc of potash like sodium peroxid sodium )erborate, ammonium perborate, sodium l)(31'(.tt]:l.)()11ttt, passions percarbonate, sodium-persttlfate, potassium persuli'ate or ainin'dnium persulfate, in combination with othersubstances wh ch do not oppose but assist or supplement the washing and clean ing effect.

It has been attempted to mix a peroxidized compound with soap and it has been asserted that it is necessary to do so, in order to preserve sufiiciently the oxygen until use by incorporatii'ig the peroxidized compound in the soap body. It has, however, been discovered, that this is not necessary and that. these peroxidizcd compounds as hereinhefore described are quite well preserved without the assistance of soap. On the other hand soap, on account of its fatty and adhesive properties, is not so conveniently and easily mixed with peroxidizcd compounds like other substances such as borax, or sal ammoniac or soda, etc, which hit Tc a cleaning-effect of tli'cir own. The peroxidizcd compounds furnish an entire substitute for soap in washing and cleaning, and by adding to them substances like the before named which readily mix with the peroxidize l compounds, the further advantage is obtained,that the admixture of soda. eto..acts on all impurities which can be removed Inechanically, while the oxygen removes those v by the other cleaning substance.

impurities which are not affected or removed The latter 0 may be a much less expensive material than soap and assist in further reducing the cost of the per-oxidized compound to the consumer, while having additional action as before stated.

The peroxidized compounds with the ad mixtures as described will not prove harmful to the fiber or color of the textiles or other organic substances, nor present any danger whatever.

As an example of the practicable use of the invention it has been found satisfactory to combine 80 to 90 parts oilsodium perb'orate with 20 to 10 parts by weight of borax.

this mixture 3 ounces by weight have been found to give satisfaction when used with 3 gallons of water. It is obvious that other proportions can be employed according to special conditions or as to the object to be attained.

The composition of matter as described is dissolved in cold or warm water, or, if the action of the oxygen is desired to be accelerated, the water will be gradually heated to boiling point. In either case a homogeneous solution of the component parts is quickly efi'ected. It is obvious that instead of one substance like soda there can be used 2 or more different powders of like properties as an admixture, for instance 5 to 10% borax and 5 to 10% soda or other proportions as desired. In the same manner several peroxidized compounds, with borax or soda in suitable proportions, can be mixed.

There are other peroxiclized compounds than those herebefore mentioned such as peracid salts of the alkaline earth metals like perborateof magnesium, or peroxids of the alkalme earth metals like calcium )erxid or magnesium peroxid, or'HWfi-li'tdd salt of afi'fif'lfi'tfiifike zinc erborate, etc., which require the addition of an i preferably solid) acid like oxalic, or citric, or an acid salt like bi-sulfate BT'soda, 1n the necessary proportion, to liberate their oxygen more freely in plain water. By the use of the term peroxidized compounds it is not intended to limit the scope of this invention to any particular peroxidized compounds. The term harmless is intended to distinguish those compounds, which will not cause spontaneous combustion with organic matter from those which will cause such.

It is obvious that other elements may be added to the mixture as a filling or to accomplish other results not inconsistent with the use of such mixture Without departing from the spirit of the invention. It is also clear that without departing from the spirit of this invention the composition of matter, instead of in a pomler form, can advantageously be used also in Eoinpre's'sed tablet form, whenever it is desired.

\Vhat is claimed and desired to be secured by Letters Patent is 2-- 1. A substitute for soap for washing, cleaning and bleaching purposes consisting of a mixture of a harmless peroxidized compound and soluble inorganic alkaline material.

2. A substitute for soap for washing, cleaning and bleaching purposes consisting of a. mixture of a harmless peroxidized compound and alkaline material comprising borax.

3. A substitute for soap for washing, cleaning and bleaching purposes consisting of a mixture of a harmless peroxidized compound, soda and borax.

4. A substitute for soap for washing, cleaning and bleaching purposes consisting of a mixture of sodium perborate and alkaline material comprising borax.

5. A substitute for soap for washing, cleaning and bleaching purposes consistin of a mixture of sodium perborate, soda and borax.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
