Description

The object of the invention is odor-binding substance mixtures which, due to their highly prominent ability to remove existing unpleasant odors and/or to prevent such unpleasant odors from occurring, can find application in many

prevails, both in the cosmetic area and otherwise in general for industrial use. In particular embodiments of the invention, the new substance mixture also exhibits a pronounced fungistatic effect, so that the area of application for substance mixtures according to the invention is thereby expanded in a corresponding way.

Due to people's increasing tolerance for odor problems, there have already been numerous proposals for remedies that either prevent unpleasant odors from occurring in advance or also improve or remove existing odors. If bacteria and fungi participate in dissolution processes that lead to unpleasant odors, then bactericidal and fungicidal agents can act as odor inhibitors, as they act as disinfectants to hold back the reproduction of bacteria and fungi, and thus the beginning of dissolution. These include, for example, in the area of cosmetics, hexachlorophene, "raluben"

(antiseptic based on halogenated phenols) and "Bidiphen" (antiseptic containing bis-(2-hydroxy-3,5-dichlorophenyl)-sulphide). Existing odors are not affected by these agents.

To improve existing odors, volatile, almost pleasant-smelling and relatively cheap substances are often used, which even in small quantities cover or improve unpleasant odors from chemicals, technical preparations, etc. Such funds are e.g. used for petroleum products of various kinds, for room care products, lacquers, rubber products, etc.

If you don't just want to cover up or improve an existing smell, but remove it, you can use an agent of the type n-lauroyl methacrylates, which is suggested for room air improvement. In this way, the odorants are bound by complex formation, whereby there should be effective hydrogen bridges, vinyl groups, dipole forces and Van der Waals forces. Such agents are not suitable for use in cosmetic or pharmaceutical preparations.

With regard to cosmetic deodorization, two ways have been used up to now, namely to inhibit the secretion of sweat and to disinfect the skin. The main effect of the antiperspirant substances for this purpose is that they exert a tanning effect on the skin and thus prevent the outbreak of sweat.

Such substances are generally aluminum compounds, both inorganic and organic in nature, possibly combined with sodium. Inorganic compounds of this nature are various strongly basic aluminum chlorides. Pure organic complex compounds of aluminum are mentioned, for example, in U.S. Pat. Patent Document No. 3,030,274. Most common in this context are aluminium, respectively sodium-aluminium salts, of organic acids, which may also be halogenated (German explanatory document no. 1.122.221).

1 Instead of aluminium, zirconium is also proposed

in analogous compound classes, partly also together with alkali. Compounds of this type are discussed in U.S. Pat. patent document no. 2,732,327, while the preparation of antiperspirant preparations from these compounds is disclosed in U.S. Pat. Patent Document No. 2,889,253. As organic acid residues for all these compounds, lactic acid or chlorinated lactic acids as well as stearic acid are mentioned almost exclusively.

Also the use of zinc compounds, respectively zinc salts for this purpose is often discussed, thus e.g. by Schriimpf in his "Lehrbuch der Kosmetik" (W. Mandrich-Verlag, Vienna, 1964). He lists zinc lactate, zinc acetate, zinc phenol sulfonate, zinc salicylate, zinc tannate, as well as zinc dimethyldithiocarbamate as mild astringents for the purpose mentioned. Due to their astringent effect, which, however, acts less strongly as a skin irritant than the corresponding aluminum salts, the undecane zinc, possibly together with the undecane magnesium, was discussed in relation to cosmetics (German patent no. 6:01,474 and German patent no. 633,661).

A proposal from more recent times (Janistyn, Taschenbuch der modernen Parfumerie und Kosmetik, Stuttgart 1966) refers to the already known zinc compounds now only as cosmetic aids, and now lists only zinc-4-phenolsulfonate of zinc compounds under deodorizing substances. The suppression of transpiration by means of skin coloring substances, e.g. aluminum compounds, as is known, have a very unfavorable effect on the general skin functions, and are, if at all, only tolerated for a limited time without irritating.

Chlorinated hydrocarbons of various compositions, which nowadays are mainly used in the industry as deodorizing preparations, are, as a result of their effect, practical disinfectants. Their effect is due to the fact that they kill sweat-soluble bacteria. This most used second way to deodorize the disinfection is nevertheless not without its problems. It is even possible, by killing all microorganisms, to bind the biologically conditioned oxidation pattern. The special bacterial flora of the skin can thereby be slightly damaged, or even destroyed, that the skin function suffers during the time such preparations are effective. Thus, for example, the fatty acid fermentation in the skin is stopped as a result of the absence of bacterial flora that has been killed by the disinfectant. Pathological skin reactions can thereby be provoked.

Guided by these considerations, new substances were developed, which not only in the field of cosmetics open a completely new way to the gentle deodorization of transpiring skin areas, but which, due to their long-lasting and strong action on the one hand and their easy availability on the other , can also find application in the most diverse areas of industrial technology. For the cosmetic sector, it is also of particular importance that substances or substance mixtures that fall under the scope of the invention can display a specific fungistatic effect, whereby odor-binding dissolution reactions based on fungi activity can be bound without simultaneously destroying bacterial life patterns. Components with unpleasant odor properties, which are either formed or already present, are taken up with great effect. The new substances or substance mixtures also bind not only strong-smelling organic substances with low molecular weight, such as mercaptans, amines, thioethers, etc., but also odorous substances of more complicated composition. The new agent, which is also distinguished by a particular skin compatibility, is thus suitable both in the area of cosmetic deodorization and for preventing the formation or destroying odors originating from plants or animals, e.g. in barns, processing companies for plant and animal products, for example in the fish processing industry, but also in the household and in the technical industry.

It was surprisingly found that salts, and especially salts which are sparingly soluble or insoluble in water, of higher carboxylic acids which are on the one hand unsaturated and on the other hand substituted with at least one hydroxyl group, are excellent agents for the desired purpose.

The object of the invention is in accordance with this

an agent with an odor-binding and possibly disinfecting effect,

which is characterized by a content of poorly water-soluble or insoluble salts of mono- and/or multi-hydroxylated, olefinically unsaturated carboxylic acids with at least 17 C atoms, and in addition, optionally

a) sparingly soluble or insoluble in water synergistically acting salts and/or esters of multi-hydroxylated saturated carboxylic acids with at least 17 carbon atoms, and/or b) sparingly soluble in water; or insoluble synergistically acting salts of partially hydrogenated phenanthrene derivatives, especially salts of diterpene carboxylic acids, and/or c) a synergistically acting mixture of salts and/or esters of hydroxylated carboxylic acids extracted from tall oil,

and or

d) a reducing agent, e.g. a skin-burning reducing agent of the type ascorbic acid or α-tocopherols and/or theirs

connections. The known carboxylic acids usually form together with polyvalent metal cations, for example divalent or trivalent cations, compounds which are insoluble or barely soluble in water. For the purposes of the invention, such metals are also particularly suitable as cations, which do not develop a catalytic activity in dissolution reactions for higher carboxylic acids, as is known, for example, for metals of the iron, copper or nickel type. Another point of aim for the choice of cations in the substances according to the invention, which as a rule must be observed, is the requirement for physiological harmlessness. In view of these assumptions, the alkaline earth metals and well especially magnesium and to a certain extent

calcium, aluminum and above all also zinc, of particular importance. The zinc salts show a pronounced fungistatic effect and are therefore particularly important in areas of application where there are fungicidal reactions to be broken, for example also in the cosmetics area for humans and animals.

The anions of the salts in the agents according to the invention are derived from higher carboxylic acids, which are at the same time unsaturated, and preferably monovalently or polyvalently olefinically unsaturated and monovalently or polyvalently hydroxylated. However, carboxylic acids which correspond to the range of C-numbers from 17 - 21 are above all suitable, especially C 1? - Cigarettes. The availability of compounds in this group is relatively limited in practice, so that for the purpose of the invention, particular preference is given to such unsaturated and at the same time hydroxylated carboxylic acids with a C number of 17 and above, which are easily available. This primarily concerns higher unsaturated and hydroxylated fats. acids. The most important representative that occurs in nature is ricinoleic acid. But the reaction product obtained by hydroxylation of polyunsaturated fatty acids can also be significant,

for example of the type linoleic acid or linolenic acid. As is known, it is relatively easy to hydroxylate one of the two double bonds in these diolefinically unsaturated carboxylic acids by a mild oxidation treatment, so that dihydroxylated but at the same time still unsaturated carboxylic acids are produced in this way. These and comparable carboxylic acid types are of particular importance within the scope of the invention.

The important salts for the purpose of the invention are the zinc, magnesium and/or aluminum salts of ricinoleic acid, ricinelaidic acid, dihydroxyoctadecenoic acid, which can be easily extracted from linoleic acid, as well as the corresponding salts of poly-hydroxylated, mono- or poly-unsaturated carboxylic acids from oxidation of linolenic acid.

As already discussed in detail, the zinc salts are of preferred interest for specific application purposes. Of the compound groups according to the invention, zinc ricinoleate is therefore particularly easily available, and as a result occupies a special position within the scope of the invention. This zinc salt of ricinoleic acid has practically no astringent effect, so that the irritation of the skin is completely absent. The zinc ions exert, especially in interaction with the hydroxyl groups present at the same time, a mild fungistatic effect, so that the formation of biological metabolic products, which partially ferment the dissolution of sweat constituents and cause the formation of substances with an unpleasant smell, is greatly reduced or completely prevented. The presence of the hydroxyl groups, as well as the unsaturated character

of the acid residues, causes a partly adsorbing and partly chemically dominant complex binding of the egg white and fat-degrading ferments, so that a deodorizing effect is achieved which is at the same time extremely good, which sets in quickly and which persists for a long time.

The depot effect for such a deodorizing substance is enhanced by the very good adhesion of these practically water-insoluble salts, whereby the substance can be fixed on the skin for a long time. There is no danger of it being torn off the clothes or washed away by sweat secretion. It is also advantageous with regard to the sustained effect that the compounds mentioned have a very low vapor pressure, so that diffusion away due to body heat is practically excluded.

It was further found that the specific properties of zinc ricinoleate and the compounds used within the scope of the invention can be synergistically enhanced by co-using another group of compounds. These synergistically active compounds refer to compounds which are likewise poorly soluble or insoluble in water, of multi-hydroxylated carboxylic acids with at least 17 C atoms. These multi-hydroxylated carboxylic acids can be of a saturated nature, whereby once again those are preferred which are practically available compounds. Relatively easily accessible are the oxidation products of unsaturated fatty acids of the type oleic acid, ricinoleic acid, linoleic acid and linolenic acid. The oleic acid leads to the mild oxidation to dihydroxystearic acid, the ricinoleic acid to trihydroxystearic acid, and higher unsaturated acids to correspondingly higher hydroxylated products.

In accordance with the invention, these acids are also preferred as salts of the aforementioned type, and here also specifically introduced as esters. The salts of zinc, magnesium, aluminum and/or esters of these polyhydroxylated carboxylic acids are thus of particular importance for the purpose of the invention. Particularly important representatives of the compound group are aleuritic acid (trihydroxypalmitic acid), dihydroxystearic acid (from oleic acid), trihydroxystearic acid (from ricinoleic acid), tetra-hydrostearic acid (from linoleic acid) as well as completely hydroxylated products of higher unsaturated carboxylic acids, for example linolenic acid.

These compounds, and for example trihydroxystearic acid in particular, add a pronounced synergistic effect for odor binding, when they are mixed with compounds from the first-mentioned substance group of unsaturated hydroxylated carboxylic acids. But these synergistic compounds should by no means be of a saturated nature. They can also be unsaturated, and especially rao-o-olefinic unsaturated.

As already said, they are water-insoluble or poorly soluble compounds of the synergistic substances, for example salts of the same type as the salts in the main substance group. The tasks listed there for cations also apply here. Thus, magnesium, calcium and/or aluminum salts are of particular importance, but this also applies here primarily to the zinc salts. The task also applies to the zinc salts of these synergistic compounds that they have excellent compatibility when applied to the human body, so that even severe allergy sufferers can tolerate the mixture without being irritated. The normal fat metabolism in the skin is not damaged in any way, so that for this reason there is no need to fear skin irritation as a result of long-term continuous use.

Within the scope of the invention, however, these synergistic components are preferably used as esters of the aforementioned higher carboxylic acids. Especially preferred are the esters of these acids with monohydric alcohols, whereby here lower alcohols with especially 2-6 C atoms are particularly suitable. It is also of particular importance that the synergistic effect increase seems to occur already when limited quantities of the synergistic substance are added to the main substance. Thus, for example, it has been shown that already amounts of from about 0.5 to about 10 weight?fc, of the total weight, of synergistic compounds, lead to a significant increase in the effect of odor destruction. Particularly preferred within the framework of the invention is to use substance mixtures which, in relation to the total weight, contain 1 to 5% by weight of the synergistic substance, next to the main substance. A further synergistic effect increase, which particularly unfolds in combination with the first synergistic substances, is possible by co-using another compound group. Here, there clearly seem to be interactions between the components, which seem to affect both the odor-eliminating effect and a favorable effect on the duration of the effect. Such a mixture of all the components also leads in particular to annihilation of the inherently unpleasant odors of the ricinoleic acid compounds. This refers to salts of partially hydrogenated phenanthrene derivatives, and furthermore especially salts of carboxylic acids of diterpenes. Examples of substance groups that are relatively easily accessible in practice are salts of abietic acid and/or laevopimaric acid. With regard to the definition of the cations, what has previously been stated for the main substance, respectively for the first synergistic substances, also applies to these salts. Here, too, salts of alkaline earth metals, aluminum and especially zinc are given special importance. By co-using these compounds from other synergist classes, not only an increase in effect in the prevention or destruction of odor is achieved, a second strengthening of the adhesion effect can also be achieved. These other synergistic substances can also be added in limited quantities. Mixing ratios of about 1 to 30 parts by weight are suitable, for example, preferably quantities from about 3 to 10 parts by weight, in relation to the overall mixture. In a particularly simple way, in accordance with the invention, a mixture of synergistic substances of the aforementioned first and second groups can be used, which can be obtained by processing tall oil, and preferably purified tall oil. The tall oil contains a mixture of carboxylic acids that fall within the first and second group of synergistic compounds according to the invention. Thus, for example, from tallow oil, after removal of what is insoluble in petroleum ether and the unsaponifiable matter, a mixture can be obtained consisting of 35 to 40 <$ > resin acids, predominantly abietic acid, C2qH^002, and 65 to 60 $ fatty acids, predominantly oleic acid, linoleic acid and linolenic acid. By careful oxidation of the alkali soaps of this mixture with KMnO^ and subsequent esterification of the free • acids, respectively by precipitation of the salts, a mixture of resin acid and oxyfatty acid esters, respectively salts, which contain synergistic compounds from the first and second groups . If one more hydroxylated unsaturated fatty acid compound is added from the main substance group in accordance with the invention, for example a salt of ricinoleic acid, then an effective substance mixture can also be obtained in this simple way. ;An oxidative breakdown of the organic acid residues, ;which by itself can lead to the formation of by-products with an unpleasant smell, can, in accordance with the invention, be easily countered by adding a reducing agent. The choice of available reducing agents is based here on the later purposes of application. While for purely technical applications small amounts of a mild technical reducing agent are co-used, it has been established, especially in the field of cosmetics, the co-use of skin-compatible reducing agents of the ascorbic acid type, especially in the form of its compounds, for example as 6-palmitoyl-ascorbate or as lauroyl ascorbate. An addition of β-tocopherol or combinations derived from it has also been shown to be particularly beneficial. The amount of reducing agent is usually below 1 weight; for example amounts from 0.05 to 0.2 weight of the overall mixture are suitable. In the cosmetic area, the new substance mixtures can be used not only in the traditional deodorizing preparations, such as powders, sticks and sprays including agents for intimate care, but the new substances can also be successfully introduced in skin care products such as soaps, creams and skin milks, in foot care products and in hair care products. Especially in the area of hair cosmetics, it is beneficial that, on the one hand, the nocardia is not attacked, and on the other hand, that the sulfhydryl reaction of cystine synthesis and thereby keratinization, is not damaged by the zinc content, but is even obviously promoted. The fungistatic effect of the new substance mixtures, which is especially present when zinc is present as a cation in at least one of the substance components, can be utilized in a variety of ways. If the cosmetic preparation contains only a limited amount of the substance mixtures, for example amounts from 0.5 to 20% by weight, then the deodorizing character dominates in the composition. The appearance of new unpleasant odors is partly prevented, and partly newly appearing unpleasant odors are bound as soon as they occur. A further area of application is for deodorizing impregnation of textiles, such as clothes and laundry, and of cellulose articles, for example rags and products for women's menstrual hygiene. Also in all these cases, the high adhesiveness of the substances according to the invention is of particular importance for their industrial utilization. Especially also the adhesion ability on fibers of natural and synthetic origin. The substance mixtures according to the invention can also be added as deodorizing detergent components which are drawn onto the fibers during washing. Further areas of application are, for example, room care agents, such as bone mass, polish and ironing agent. It is also possible to use it in air conditioners, for example room sprays, as well as for deodorizing large rooms, e.g. in stables, in processing companies for plant and animal products, such as fish processing companies, etc. The strong odor-binding properties also appear interesting when binding odors in waste materials. In the following, some examples of the production of substance components for use in the agents, and some substance mixtures as well as final agents using the substance mixtures, are primarily discussed. ;1. Preparation of zinc ricinoleate. 25 1 commercially pure castor oil is saponified in a known manner by the portionwise addition of 7.8 1 38% caustic soda and 40 1 water. To the clear sodium ricinoleate solution, at approximately 80°C, 12.5 kg of zinc sulphate heptahydrate DABg which is dissolved in water to a volume of 25 1 is added, stirred thoroughly and then allowed to settle. The zinc soap is then separated from the mother liquor and, while still hot, poured into moulds, where it solidified. ;2. Preparation of trihydroxystearic acid. ;The solution of sodium ricinoleate obtained after 1.) was acidified with sulfuric acid to pH 2, whereby the fatty acids of the castor oils are separated. 3.0 kg of these acids are saponified with 3.45 1 potassium hydroxide at 20° 1.2 7 « 28.29% by weight and 100 1 ; water. To the cold clear potash soap solution, 3 kg of KMn04 in 200 1 of water are added while cooling. The potassium soap solution of trihydroxystearic acid is then filtered from the manganese oxide hydrate. From the clear solution, the zinc salt can be precipitated as under 1.), for which 1.45 kg of ZnSO^ is required. 7HJ3 ;DAB6, in 10 1 water. The alkaline earth salts can be precipitated in the same way. The free acid is separated by acidification to pH 2. 3. Production of trihydroxystearic acid ethyl ester. 3 kg of trihydroxystearic acid is suspended in 10 1 abs. ethanol. While stirring at room temperature, chlorine hydrogen gas is slowly introduced until the acid has dissolved so that there is almost no residue left. The alcoholic ester solution is filtered from a negligible residue, and then the ester is precipitated by emptying the alcoholic solution into a tenfold volume of warm. It is separated by filtration and dried. From the filtrate, the excess ethanol is recovered by distillation. ; 4. Production of ricin-elaidic acid. ;The castor oil acids obtained after 1) and 2) from 50 kg of castor oil are heated raw with 20 1 (50 - 60°). With good stirring, a solution of 1.2 kg of sodium nitrite in 15 1 of water is allowed to flow in, maintained for another 10 minutes at 50 - 60°C and then cooled quickly, e.g. by adding ice. The reaction product separated from the aqueous phase can be further processed crudely as ricinoleic acid. The pure ricin-elaidic acid is recovered by extracting the reaction product with boiling ligroin and crystallising out on cooling; ;5. Production of dihydroxy-octadecenoic acid. 2.8 kg of linoleic acid is saponified as described under 2) with 3.45 1 potassium hydroxide at 1.27 and 100 1 water, and then oxidized with 3 kg KMhO^ in 200 1 water under good cooling, and then further processed as previously described. 6. Production of tetrahydroxystearic acid. ;Manufacturing takes place as under 5), but only 6 kg of KMnO^ in 200 1 of water is used for the oxidation of potash soap from 2.8 kg of linoleic acid. 7. Processing of tall oil raffinates, The tall oil raffinate, which has been freed from the insoluble in petroleum ether and the unsaponifiable matter, is saponified after 2) with aqueous potash to a clear potash soap solution, and is oxidized with a thin KMnO^ solution. From the clearly filtered soap solution, either after 1) the corresponding Zn, Al or alkaline earth salts separately, or after mixing the soap solution with the alkali ricinol-eat solution, substance mixtures of a similar composition can be precipitated. After acidifying the potassium soap solution with sulfuric acid to pH 2, the free acids can also be recovered, and after the purification according to 3) be esterified. The amount of potassium hydroxide for neutralization, as well as of KMnO^ for oxidation, depends on the composition of the tall oil raffinates as well as on the desired degree of oxidation of the unsaturated fatty acids. ;Substance mixture A; ; 95 parts zinc ricinoleate ; 3 " zinc cabietate ; 2 parts zinc hydroxystearate and ; 0.05 " 6-palmitoyl ascorbate, ; produced by joint saponification of castor oil and rosin-balsam resin WW, addition of potassium trihydroxystearate and joint precipitation of the zinc salts with zinc sulfate heptahydrate DAB, and addition of the antioxidant to the liquid organic phase. ;Substance mixture B ;95 parts zinc ricinoleate, ;3 "zincabietate, ;2 "trihydroxystearic acid ethyl ester and ;Q.05 "jC-tocopherol, ;produced by joint saponification of castor oil and balsam resin WW and addition of the trihydroxystearic acid ethyl ester as well as the antioxidant to the liquid organic phase. ;Substance mixture C ;50 parts zinc ricinoleate, ;45 " zinc ricine laidinate, ;3 "zincabietate, ;0.1 " lauroyl ascorbate and ;2 "tetrahydroxystearic acid ethyl ether, ;produced by joint saponification of castor oil and balsam resin WW, addition of sodium ricin elaidinate, co-precipitation of the zinc salts, and addition of tetrahydroxystearic acid ethyl ether and lauroyl ascorbate to the liquid organic phase" ; Substance mixture D ; 92.9 parts zinc ricin elaidinate, ; 5 " zinc abietate, ; 2 " tetrahydroxystearic acid ethyl ester and ; 0 ,1 sk-tocopherol, produced by co-precipitation of the zinc salts from the alkali salt solution, and addition of tetrahydroxystearic acid ethyl ether as well as the antioxidant. ;Substance mixture E ;9 2.9 parts syncricine laidinate, ;3.5 " magnesium abietate, ;3.5 " magnesium leuritinate and ;0.1 " 6-palmitoyl ascorbate, ;produced by co-precipitation of the magnesium salts, and addition of these as well as the antioxidant to syncricine laidinate. ;Substance mixture F ;50 parts zinc ricinoleate, ;40 H zinc ricine laidinate, ;2 "zincabietate, ;5 aleuritic acid ethyl ester, ;3 trioxystearic acid ethyl ester and ;0.05 "<e(-tocopherol, ;produced by joint saponification of castor oil and balsam resin WW, addition of sodium rieinelaidinate, co-precipitation of the zinc salts and addition of the ester as well as the antioxidant. ;Substance mixture ;50 parts zinc ricinoleate, ;45 " zinc dihydroxyoctadecenate, ;3 " zinc abietate, ;2 " tetrahydroxystearic acid ethyl ester and ;0, 1 "o^-tocopherol, ;produced by joint saponification of castor oil and balsam resin WW, addition of potassium dihydroxyoctadecenate, joint precipitation ;of the zinc salts and addition of tetrahydroxystearic acid ethyl ester and antioxidant. ;Substance mixture H ;50 parts zinc ricinoleate, ;45 "magnesium ricinoleate , ;5 " ethyl ester of the synergistically acting mixture ~ r -, '■ ^ \ i -u j. extracted from tall oil and 0.05 " 6-palautoyl ascorbate, J * prepared by precipitation of sodium ricinoleate with a solution of zinc and magnesium sulfate as well as the addition of the hydroxylated tall oil ester and the antioxidant.
