Representative of such active compounds which can be utilized in the compositions of this invention are set forth in Table I, below:
I. Preparation of Active Compounds
The active compounds having formula (I) can be prepared under atmospheric pressure by dissolving or suspending one of the corresponding acid (Ia) or basic (Ib) reactants in a solvent therefor and then adding progressively the other of said reactants, while stirring. The resulting mixture can be heated to reflux. Thereafter, the reaction mixture is left to stand for several hours at a temperature ranging between about -20.degree. to +5.degree. C. Under these conditions, the desired salt precipitates or crystallizes and can be removed by conventional separation procedures such as by filtration. Generally the basic reactant (Ib), is used in stoichiometric proportions, or slightly in excess of stoichiometry relative to the acid reactant (Ia). The acid and basic reactants can, if desired, be prepared in a manner essentially as outlined in Ser. No. 140,956 filed May 6, 1971, now U.S. Pat. No. 3,821,405.

II. Topically Applied Compositions
In accordance with the present invention, there is provided a variety of compositions which can be topically applied to the scalp or skin to achieve the aforementioned result and these compositions can include dermal preparations which can be in the form, for instance, of a cream, milk, lotion, gel, cake or aerosol. The active ingredient of this invention is present in these topically applied compositions in amounts of about 0.1-5 percent, preferably about 0.75-3 percent, by weight of the total composition. Generally, these compositions have a pH ranging from about 3 to 13 and are solutions of the active ingredient in water, a lower alkanol or aqueous solutions of a lower alkanol wherein the lower alkanol is present in amounts of about 20 to 70 weight percent of said aqueous solutions. The choice of solvent for the active ingredient can depend on a number of easily ascertainable factors such as the particular active ingredient chosen, its solubility characteristics, the ultimate use of the composition and the like. When a lower alkanol, alone or as an aqueous solution thereof, is selected, generally the alkanol is ethanol or isopropanol. In addition to the solvent, the active ingredient-containing composition can also be formulated with conventional adjuvants such as emulsifiers, preservatives, perfumes, dyes, emollients, waxes, pigments, detergents--cationic, anionic, nonionic and amphoteric, thickeners, oils and the like.
When the topically applied compositions of the present invention are employed in aerosol form, generally the active ingredient is present as a solution thereof in a lower alkanol, together with a conventional aerosol propellant such as a fluorinated hydrocarbon such as dichlorodifluoromethane, trichloromonofluoromethane and mixtures thereof. Obviously, other well-known propellants can also be used. Generally, the propellant is present in amounts of about 66 to 75 weight percent of the total aerosol composition, which is, of course, packaged under pressure.
The topically applied compositions also include hair setting lotion and lacquer formulations. Again, the active compound of this invention is present in such formulations in amounts ranging from about 0.1-5 percent by weight of said formulation, and is present as a solution thereof in water, lower alkanol or mixtures thereof as defined above. Additionally such hair setting lotions and lacquers also include, advantageously, a film-forming resin having a molecular weight ranging from about 10,000 to 3,000,000. Typical film forming resins include polyvinyl pyrrolidone having a molecular weight of about 10,000-700,000; copolymers of vinyl pyrrolidone and vinyl acetate wherein the ratio of VP to VA can range between 70:30 to 30:70 and which have a K value (1% ethanol solution) of about 20-50;copolymers of vinyl acetate, crotonic acid and an acrylic or methacrylic ester; copolymers of vinyl acetate and a vinyl alkyl ether; copolymers of vinyl acetate, crotonic acid and a vinyl ester of a long carbon-chain acid or an allyl or methallyl ester of a long carbon-chain acid; copolymers of an ester of an unsaturated alcohol and a short chain carboxylic acid, a short carbon-chain unsaturated acid at at least one ester derived from a short chain saturated alcohol and an unsaturated acid; and copolymers of at least one unsaturated ester and at least one unsaturated acid. A specific vinyl acetate/crotonic acid copolymer usefully employed is that sold under the trade name RESYN 28.1310 having a molecular weight of 20,000. Other resins usefully employed are those sold under the trade name GANTREZ including GANTREZ AN 3953 which is the half butyl ester of GANTREZ AN 119 which is methylvinylether/maleic anhydride copolymer having a specific viscosity of 0.1-0.5 in a 1% solution of the copolymer in methylethyl ketone at 25.degree. C.

Yet another topically applied composition including the active compounds of the present invention is a formulation for use in effecting a permanent wave or deformation of oily hair.
In one embodiment of the use of such permanent wave formulations, the hair is permanently waved by applying to the hair wound on curlers during the first stage, i.e., during the reducing stage, a cosmetic composition comprising a mixture of a reducing agent and the active compound of this invention as defined above, permitting the composition to remain on the hair for a time sufficient to alter the disulphide bonds of the keratin of the hair, generally about 10 to 40 minutes, thoroughly rinsing the hair to remove residual reducing agent and applying in the second stage, i.e., during the neutralization stage, an oxidizing or neutralizing agent to reform the disulphide bonds of the keratin of the hair.
In another embodiment of using these permanent wave formulations the hair is permanently waved by applying to the hair wound on curlers during the first stage, i.e., during the reducing stage, a reducing agent, permitting the composition to remain on the hair for a time sufficient to alter the disulphide bonds of the keratin of the hair, generally about 10 to 40 minutes, thoroughly rinsing the hair to remove residual reducing agent and applying in the second stage, i.e., during the neutralization stage, a cosmetic composition comprising a mixture of an oxidizing or neutralizing agent and the active compound as defined hereinbefore whereby the disulphide bonds of the keratin of the hair are reformed.
In an alternative procedure the hair is permanently waved by impregnating the hair wound on curlers with a cosmetic composition comprising a mixture of a thiol reducing agent for altering the disulphide bonds of the keratin of the hair, an organic disulphide and the active compound of the present invention, the molar ratio of said organic disulphide to said thiol being greater than 1, and as high as about 20, permitting the composition to remain on the hair for a time sufficient to induce a permanent wave therein, generally about 10 to 40 minutes, and unwinding the hair from the curlers. Conventional separate neutralization operations are not required in the practice of this embodiment of the invention.
The active compound of this invention used in these permanent wave formulations is admixed with a conventional reducing agent and is present in the resulting mixture in amounts between 0.1 to 5% by weight of the total and preferably between 1 and 3 weight percent. The pH of this cosmetic composition is preferably between 3 and 9.5. Conventional reducing agents employed are advantageously those organic thiols which are generally used to perform the first stage of a permanent waving operation. Representative thiols include thioglycolic acid, ammonium thioglycolate, thioglycerol, thiolactic acid, thioglycolic amide or hydrazide or the like.
Conveniently, and also in accordance with the present invention, the reducing composition is a two-package composition, the first package containing a thiol reducing agent as described above and the second package containing the active compound of this invention in amounts such that when the contents of two packages are mixed together, preferably just before initiation of the reducing operation, the resulting reducing composition contains said active compound in amounts of about 0.1-5 weight percent of the total mixture.
Alternatively, the said active compound is admixed with a conventional neutralizing or oxidizing agent and is present in the resulting mixture in amounts between 0.1 to 5 weight percent, and preferably between about 1 and 3 weight percent of the total. Conventional neutralizing agents employed include, for instance, hydrogen peroxide, sodium or potassium bromate, sodium perborate or percarbonate and the like.
Conveniently also, the neutralizing composition is a two-package composition, the first package containing the neutralizing agent as described above and the second package containing said active compound also as defined above in amounts such that when the contents of the two packages are mixed together, preferably just before initiation of the neutralizing operation, the resulting neutralizing composition contains the active compound in amounts of about 0.1-5 weight percent of the total mixture.
As a further alternative, the active compound is admixed with a single stage permanent hair waving agent, and is present in the resulting mixture in amounts between 0.1-5 weight percent, and preferably, between about 1 and 3 weight percent of the total. Conventional single stage permanent hair waving agents can be employed and include a mixture of an organic disulfide and a thiol, the mol ratio of the disulfide to the thiol being greater than 1.
Suitable thiols include thioglycolic acid, glycol thioglycolate, glycerol thioglycolate, .beta.-mercaptoethanol, N-carboxymethyl-mercaptoacetamide, glycol thiolactate and the like.
As the organic disulphides there can be used the disulphides of the thiols set forth in the preceding paragraph. For instance, glycol dithiodiglycolate, glycerol dithioglycolate, glycol dithiodilactate, dithiodiethanol and N-carboxymethyldithioacetamide can be employed. Additional ingredients can include ammonia, water, urea and lower alkanols in conventionally employed amounts and the pH of the single stage permanent hair waving agent ranges between about 8-10, preferably about 8.5-9.5. Typical formulations of such single stage permanent hair waving agents are disclosed in French Pat. Nos. 1,443,888 and 1,455,788.
Again, conveniently, the single stage permanent hair waving composition is a two-package composition, the first package containing the single stage permanent hair waving agent and the second package containing the active compound, as defined above, in amounts such that when the contents of the two packages are mixed together, preferably just before use, the resulting permanent hair waving composition contains the active compounds in amounts of about 0.1-5 weight percent of the total mixture.
As will be recognized, these permanent wave formulations can also include other additives conventionally employed such as penetrating agents, surfactants, dyes or perfumes and can be admixed with conventional vehicles such as water, lower alkanols and their mixtures as defined above. Further, they can also be provided in the form of a solution, a foam, a cream or gel or can be provided in the form of a sprayable aerosol especially when the cosmetic vehicle is water, lower alkanol or their mixtures. The sprayable aerosol can include an amount of a liquefied gas under pressure, such as a fluorochlorinated hydrocarbon, also as defined hereinbefore.
In yet another embodiment of the present invention, a dermal lotion composition can be prepared which contains as the active ingredient the compound defined above present in amounts of about 0.1-3 percent by weight of said composition. Additionally, where the active compound comprises a free carboxylic acid group, this can take the form of a complex with a cationic quaternary ammonium bactericide, such as (diisobutylphenoxyethoxyethyl dimethyl benzyl) ammonium chloride monohydrate or (diisobutyl cresoxyethoxyethyl dimethyl benzyl) ammonium chloride monohydrate.
III. Orally Administered Compositions
In accordance with another embodiment of the present invention, there is provided a composition and method for treating a scalp characterized by an excessive secretion of sebum, to improve the condition thereof by reducing said excessive secretion which comprises orally administering to a human being having a scalp so characterized a therapeutic composition comprising an ingestible carrier admixed with, as a non-toxic active ingredient, an active compound as defined hereinabove.
These novel compositions can be in liquid or solid form and when the liquid form is desired, the active compound can be dissolved in an alimentary liquid, such as water or an aqueous solution of a non-toxic lower alcohol, such as ethanol. These liquid orally administered compositions generally contain about 1-1.5 percent by weight of the active compound, the remainder being essentially the ingestible carrier.
The orally administered compositions can also be provided as a solid, in the form of granules, pills, tablets and the like, and in this form the active compound is generally present in amounts of about 0.75-20 weight percent of the composition. Examples of suitable excipient or carrier formulations can be found in U.S. Pat. No. 2,888,380.
These compositions, whether in liquid or solid form, can be orally administered at a rate of about 1-5 mg/kg/day based on the weight of the human being, and they are generally administered during a period of about 15 days. After 15 days, the treatment may be stopped and then resumed 15 days later.

Immediately prior to initiating the second stage of the permanent waving operation, i.e., the neutralizing stage, the powdered 5-amino 3-thia hexanedioate of 3-benzylthio-propylammonium is dissolved in the hydrogen peroxide solution and the hair previously treated with the above reducing agent, being soft and pliable and still wound on curlers, is treated with the resulting neutralizing solution for a time sufficient to reform the disulphide bonds in the keratin of the hair.
After the hair has been rinsed, unwound from the curlers, and dried, a permanent wave is obtained which exhibits good holding characteristics. Equally important, however, is that the hair remained non-oily in appearance for a significantly longer time than did the hair when permanently waved using essentially the same neutralizing composition but without compound of the invention.
