Original No. 2,815,344, dated December 3, 1957, Serial No. 509,695, May 19, 1955. Application for reissue June 3, 1959, Serial No. 817,962

9 Claims. (Cl. 260-247.1)

Matter enclosed in heavy brackets 1 appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.

This invention relates to novel polythionates and to their preparation.

This application is a continuation-in-part of my co,- pending application Serial No. 315,827 filed October 20, 1952, and now abandoned.

Inorganic salts of polythionates, including stabilized aqueous solutions thereof, have found application in the cosmetic and other fields as adjuvants for different products, such as hair tonics, etc. Where, however, it is desired to apply such polytln'onates to cosmetics containing alcohol or consisting chiefly of fatty or waxy materials, difiiculties have been encountered because of their poor solubility in such media. Another objection to'alkali metal polythionates heretofore used is that in order to maintain them stabilized it is generally necessary to maintain them at a low pH, e.g., 3 or less. This seriously interferes with their use in many fields in which neutral or slightly acid conditions are desired.

It is among the objects of this invention to provide a stable polythionate composition which is soluble in a1- cohol and remains stable in acid or neutral media.

Another object is to provide a polythionate composition which in addition to the therapeutic properties attributable to the presence of the polythionate radical, has desirable germicidal properties.

Still another object of the invention is to provide a method of producing such polythionate compositions.

Other objects and advantages of this invention will be apparent from the following detailed description thereof.

The novel polythionate compounds are of the general structural formula:

In compound 9 above the alkyl group contains 12 carbon atoms.

The novel crude quaternary ammonium polythionates are wax-like compounds. Upon purification, for example, by filtration with activated carbon and crystallization from solution, they are semi-crystalline or crystalline in character. Compounds of penta, hexa and higher polythionates are substantially insoluble in water provided that the cation (quaternary ammonium base) has a molecular weight of 232 or more. Tetrathionate compounds having a molecular weight below 232 are some what soluble in water. These compounds generally form viscous aqueous solutions.

The substantial insolubility in water of the penta, hexa and higher polythionates is indeed surprising because both the quaternary ammonium base and the polythionates are readily soluble in water, and the polythionic acids are known to be very strong acids, even stronger than sulfuric acid. Unexpectedly, however, I have found that the reaction of a quaternary ammonium base having a molecular weight in excess of 232 and of the type herelnabove set forth, and a penta or higher polythionate results in quaternary ammonium polythionate compounds which are practically insoluble in water. They are stable, i.e. do not readily decompose, and this is the case even when the media in which they are incorporated are neutral or slightly acid.

The stability of the compounds of this invention is also unexpected, because the inorganic polythionates, including the alkali metal salts thereof, are unstable and tend to deposit sulfur in neutral or slightly acid media and at times even in strongly acid media. Thus, aqueous solutions of potassium pentathionate and potassium hexathionate, even in a half normal hydrochloric acid solution, show signs of precipitation of sulfur after a few minutes at temperaturescf 25 C. This precipitation of further the product becomes crystalline.

sulfur takes place simultaneously with the formation of lower polythionic acids. The compounds of this invention, on the other hand, in the absence of water, remain stable indefinitely. An aqueous suspension of the compounds of this invention at a pH of 1 remain stable for long periods of time, and this is particularly true of the quaternary ammonium trithionate, tetrathionate, pentathionate, and hexathionate. Their stability has been found sufiicient, without the addition of any stabilizers, to allow the production of alcoholic solutions or aqueous suspensions for technical, cosmetic and therapeutic uses. Evidently, the quaternary ammonium cation has a stabilizing effect on the polythionate molecule.

The polythionates of this invention are unstable in the presence of alkali. When treated with alkaline solutions they rapidly decompose to form the corresponding thiosulfates.

The polythionates of this invention are soluble in alcohols, e.g., ethyl alcohol, isopropyl alcohol, etc., and in many organic solvents, particularly the chlorinated hydrocarbons, such as dichloroethylene.

The properties of the compounds of this invention vary with the size of the polythionate molecule and with the molecular weight of the cation. Thus, the bis-(dodecyl acetamido dimethyl benzyl) polythionate is soluble in waxes, such as those used for lipstick manufacture, and hence can be efliciently introduced into lipsticks. Most of the quaternary ammonium polythionates, however, are substantially insoluble in hydrocarbons. They have a high phenol co-eflicient, i.e., germicidal eificiency. However, the larger the sulfur containing anion in general, the smaller the phenol co-eflicient.

The compounds of this invention are prepared by reacting an alkali metal polythionate, preferably the potassium polythionate in aqueous solution, with an aqueous solution of the quaternary ammonium base. The reaction readily takes place as long as at least A mol of polythionate is present per mol of quaternary ammonium base, and the medium in which the reaction occurs has a low concentration or contains no chlorine (C1) or sulfate (50,) ions.

The reaction may be carried out at any temperature below the decomposition temperature of the reactants or of the reaction product. It proceeds readily at room temperatures (2025 C.), and, hence, it is preferable to operate at room temperatures. Desirably, the reaction is carried out in the presence of a solvent for the quaternary alkyl ammonium polythionate product. A preferred solvent is dichloroethylene.

The following examples are given for purposes of illustrating the invention. It will be understood that the invention is not limited to these examples.

GROUP I-EXAMPLES IN WHICH R AND R OF THE FORMULA 1 ABOVE ARE A HY DROCAR- BON AND AN ALKYL GROUP, RESPECTIVELY Example 1 A solution of 50 grams of potassium tetrathionate in 1,000 cc. of water is acidified to a pH of 1 with hydrochloric acid. To this solution is added 100 cc. of a 50% solution of lauryl trimethyl ammonium chloride in isopropyl alcohol and 100 cc. of dichloroethylene while stirring. When the reaction is complete, e.g., after about 10 minutes, the dichloroethylene layer is separated from the aqueous phase and Washed with water. There after, the dichloroethylene solvent is evaporated by blow ing air over the surface of the solution. The residual waxy solid is dried by exposure to the atmosphere at room temperature.

Upon analysis of this waxy solid by titration (after decomposition with potassium cyanide and sulfite) it shows a content of bis-(lauryl trimethyl ammonium) tetrathionate; the remaining 10% is water. If dried out By the substitution of potassium pentathionate and hexathionate, respectively, for the potassium tetrathionate of this example bis-(lauryl trimethyl ammonium) pentathionate and hexathionate result.

Example 2 This example difiers from Example 1 in the substitution of potassium trithionate and octadecyl trimethyl ammonium chloride for the potassium tetrathionate and lauryl trimethyl ammonium chloride, respectively, of Example 1. Bis-(octadecyl trimethyl ammonium) trithionate results. This product is a semi-crystalline solid.

Example 3 In this example, octadecyl trimethyl ammonium chloride is substituted for the lauryl trimethyl ammonium chloride of Example 1. Otherwise, the procedure is the same. Bis-(octadecyl trimethyl-ammonium) tetrathionate results. This compound is a semi-crystalline solid.

Example 4 This example differs from Example 1 in the substitution for the potassium tetrathionate of a solution containing a mixture of equal parts of pentaand hexathionate. A substantially pure bis-(lauryl trimethyl ammonia) hexathionate is first obtained as a precipitate. After most of the hexathionate has been precipitated from the solution, a precipitate of the bis-(lauryl trimethyl ammonium) penathionate is obtained. In this manner fractionation of the mixture of hexa and pentathionates may be effected.

Example 5 1,000 grams of crystalline sodium thiosulfate are dissolved in 10,000 cc. of water, the resultant solution filtered and 4 kg. of crushed ice are added. 200 cc. of S C], are dissolved in 400 cc. of ethyl ether. This solution along with 250 cc. of concentrated sulfuric acid are poured into the thiosulfate solution while stirring vigorously. The solution is then agitated by blowing air therethrough for 3 days. The sedimented sulfur is filtered off. Blowing of air through the solution is continued for 14 days, and then 20 cc. of a saturated solution of cupric acetate are added. The resultant solution is concentrated by evaporation at temperatures not over 30 C. to form a viscous solution, and the precipitated sodium sulfate is removed from this solution. The solution 'is then diluted with water to a volume of 1,000 cc., and cc. of 50% lauryl trimethyl ammonium chloride are then added together with 25 cc. of dichloroethylene. The dichloroethylene solution is then separated from the aqueous phase, and the solvent removed by evaporation.

A somewhat oily and sticky product results; this product is bis-(lauryl trimethyl ammonium) polythionate containing an average of from 8 to 10 sulfur atoms per molecule of compound. This compound is soluble in alcohol and chlorinated solvents. It is readily decomposed by alkali.

By the addition of another 10 cc. of 50% lauryl trimethyl ammonium chloride and 25 cc. of dichloroethylene to the reaction product, a new compound may be obtained having a lower average sulfur content, but containing more than 6 sulfur atoms per molecule. The new product contains about 7 to 8 sulfur atoms per molecule.

i The new compounds of this invention possess the therapeutic properties of the polythionates and the germicidal, bactericidal and tungicidal properties of the quaternary ammonium compounds forming the cation of the compound. Hence, they can be used in the manufacture of cosmetics, such as hair tonics, lipsticks, face creams, etc., and also for medicinal uses, as an adjuvant in preparations for the treatment of skin infections, e.g., dermatological preparations.

A hair tonic embodying this invention may be made by incorporating in a preparation consisting of 70% ethyl alcohol, 4% castor oil and 26% water, 3% by weight of bis-(lauryl trimethyl ammonium) hexathionate. This compound dissolved readily producing a clear stable solution which is unusually eflicacious in preventing diseases of the scalp and maintaining the latter in a healthy condition.

As many changes can be made in the above compositions and many apparently widely different embodiments of this invention can be made without departing from the scope of the claims, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.
