Description
United States Patent UNDECYLENIC ACID ALKYLOLAMIDE DERIVA- TIVES FOR CONTROLLING BACTEREA, FUNGI, AND DANDRUFF Hans Bernhard Seebohm, Steinau, Kreis Schluchtern, Germany, assignor to Rewo Chemische Fabrik G.m.b.H., Steinau, Kreis Schluchtern, Germany No Drawing. Filed July 31, 1962, Ser. No. 213,5fi8
8 Claims. (Cl. 16722) It has been previously disclosed that certain alkylol amides derived from undecylenic acid are valuable bactericidal and fungicidal agents. It has now been found that it is possible to prepare derivatives of such alkylolamides which have a greater field of usefulness. Said compounds previously disclosed were generally only soluble in water if prepared by association with free alkylolamine in the form of a complex. Otherwise, they were usually sparingly soluble or insoluble in water.
It has now been found that the compounds according to the present invention are normally appreciably soluble in water without need for the presence of free alkylolamine and, therefore, can be used not only in alkaline solution, but in neutral or even acid solution.
The compounds of this invention show marked bactericidal and/ or fungicidal effect against many, though not all, microorganisms. The preferred examples described hereinafter are particularly efiiective against fungi, such as Trichophyton menzagrophytes, which is believed to cause the condition known as athletes foot. Said preferred examples have also been found valuable in hair preparations for controlling and treating dandruff. It is sometimes assumed that dandruff is caused by a microorganism Pitylrosporum ovale and it may well be that the effectiveness of said preferred compounds is due to their activity against this organism.
It is a further feature of the new compounds and derivatives of this invention that, apart from being water-soluble, they appear to some extent to exhaust from their solution onto the hair or skin. This substantivity may well account in part for the good results obtained by treating dandrulf by shampoos containing the new compounds of the invention. These compounds or derivatives, although they may occasionally be used by themselves, will normally be employed after incorporation in a composition which comprises the active compound of this invention in association with an acceptable vehicle. The term vehicle is used herein to denote the wide variety of carriers, extenders, or diluents, which may find service in compositions containing compounds or derivatives of this invention, and is qualified by the term acceptable only in that it excludes any possibility that the nature of the composition, considered in relation to the route by which it is intended to be administered, or the use to which it is to be put, could be harmful rather than beneficial. The choice of a suitable mode of presentation for any desired administration or application is completely within the competence of persons skilled in the art of preparation of pharmaceutical, toilet, cosmetic, or related or similar compositions.
Where the composition is to be applied to the skin, the carrier may be a solid powder, such as talc; an aqueous solvent base is used Where a lotion is required and a nonaqueous solvent base, where a tincture is required. The compounds of this invention may also be applied to the skin in a composition taking the form of a cream, when the active compound will be in association with materials of the class comprising oils, fats, and waxes and water and generally an emulsifying agent.
The compounds of this invention are especially suitable for use together with soaps and with synthetic detergents, e.g., in the formulation of shampoos and skin-cleaning Patented May 28, 1968 compositions. However, the same compounds can also be employed in washing preparations not necessarily intended to clean the skin but for general cleaning purposes.
The compounds embodying the present invention may also be incorporated in other compositions. Examples of further carriers are: plastically solid bases comprising pessaries, suppositories, lipsticks, and soap tablets and cakes. The compounds may also be used in hair oils, brilliantines, hair creams and hair tonic preparations. If the compositions comprise only oil, fat and wax, the compound must normally first be dissolved in Water or other suitable solvent and this dissolved or emulsified in the main carrier.
The compounds of this invention may also be incorporated in aerosol compositions by normally dissolving them in an organic solvent composition containing a suitable propellant such as a fiuorinated hydrocarbon, or butane.
The derivatives of the alkylolamides of undecylenic acid sutiable for use according to this invention correspond to the following general formulae:
In the above formulas R is a radical selected from the group comprising hydrogen, alkyl, hydroxyl-substituted alkyl and polyglycolether, and may contain 1-4 carbon atoms when it is alkyl and hydroxyl-substituted alkyl, but may contain 1-30 carbon atoms when it is polyglycol ether; where y is selected from the group consisting of zero and an integer 1-30; m is an integer of the value 1-4; n is an integer of the value 1-3; where R and R" are selected from the group consisting of hydrogen and the radicals -SO X and O-SO X and X is selected from the group consisting of hydrogen, alkali metal, ammonium, organic amine and substituted organic amine; and where Y is selected from the group consisting of hydrogen, alkali metal, ammonium, organic amine and substituted organic amine. The compound as defined may frequently be made by reacting a suitable alkylolamide with the anhydri-de of a dibasic acid. In cases where the sulphonate is desired, this may be obtained by reacting the derivative from maleic anhydride with a sulphite. It will be appreciated that during manufacture mixtures of isomers and some side reaction products may be obtained, but impure commercial preparations will normally be suitable for the invention. Furthermore, mixtures of compounds which are individually suitable, may be used.
The preferred examples are products obtained by neutralizing with soda or an alkylolamine, the compounds obtained by reacting undecylenic acid monoethanolamide or mono-isopropanolamide, with phthalic, maleic of succinic 'anhydride and the compounds made by reacting these alkylalamides with maleic anhydride, and treating the result with sodium sulfite or bisulfite. Also suitable are the similar products obtained using in place of the stated alkylolamides the products obtained by reacting these with 1-6 molecules of ethylene oxide.
The present invention also relates to a process for inhibiting the growth of and destroying microorganisms and for the relief and treatment of diseases caused by microorganisms by using the compounds of the invention as defined, either by themselves or incorporated in a suitable composition.
The following examples illustrate some specific emsoda .in the presence-of water. A composition is then prepared, comprising 2 parts of tbematerial just described in one hundred parts of a vehicle containing thirty parts of ethyl alcohol, the balance being water.- The resulting composition or tincture can be used as a hair tonic for treating dandruff.
EXAMPLE 2 A product is prepared as in the above Example 1, using maleic anhydride in the place of succinic anhydride. The resulting compound is not neutralized but is reacted in aqueous solution at about 85 C. with sodium sulfite. An equimolecular proportion of sodium sulfite is employed and the amount of water adjusted, so that the resulting solution has a final total solid content of about 33%. The compound thus prepared in aqueous solution is added in the appropriate amount to a solution of triethanolamine lauryl sulfate and lau'ric acid diethanolamide, so that the final composition contains lparts of the lauryl sulfate, 5 parts of the diethanolamide and 2 parts of the undecylenic derivative (on a' 100% basis) just prepared,
The resulting composition can be used as treat dandruff conditions.
EXAMPLE 3 parts of olive oilare mixed at about 70 C. with 10 parts of propylene glycol'monostearate and 5 parts stearic acid, and the whole poured with stirring into a mixture containing 2 parts of triethanolam ine, 5 parts of propylene glycol and 2 parts of the undecylenic acid derivative (on a 100% basis) as prepared in the above Example 2 and 66parts of water. These latter ingredients are all at a temperature of 40 C. Stirring is continued while the whole mix is cooled to 30 C. The resulting cream may be applied to the skin to treat fungicidal conditions.
It will be appreciated from the above that this invention is not limited to the embodiments, conditions, steps, etc. specifically described herein and can be carried out with various modifications within the scope of the invention as defined in the appended claims. Thus, in the compounds of the invention, the symbols R, X, Y, etc., may stand for the various radicals, substituents, groups or reactants, or their mixtures, as described in the application. The various products embodying the invention can be prepared by processes and under conditions which are substantially analogous to those more specifically described in the above Examples 1-3. The solvent used as a carrier may be an aqueous or non-aqueous solvent or a mixture and may contain a synthetic detergent in solution or suspension. The products of the invention may be used in combination with soap and/or'synthetic detergents. They may also be used for sterilization of articles or surfaces or the like, infected by microorganisms.
