Description
Die vorliegende Erfindung betrifft feste, formbeständige Luftverbesserungspräparate mit langdauernd und nahezu konstant verdampfendem Wirkstoff zur fortdauernden Befestigung von unerwünschten Gerüchen in Räumen. Der Gegenstand des Hauptpatents Nr. 582003 ist im Gegenstand der vorliegenden Erfindung nicht inbegriffen.
Feste, formbeständige Luftverbesserungspräparate in Form fester Lösungen von flüchtigen Menthadienen in harten Polymeren, wie Polyäthylen oder Äthylcellulose, sind bereits aus der US-Patentschrift 2 865 806 bekannt. Solche Luftverbesserungspräparate weisen aber keine genügende Festigkeit, keine langdauernde Formstabilität sowie keine zufriedenstellende Wirksamkeit auf. Sie ermöglichen zwar eine Deckung mancher unerwünschten Gerüche, aber keine tatsächliche Vertilgung derselben. Da sie mit wachsender Abgabe des Wirkstoffes zerfallen oder zerbröckeln, bieten sie nach zwei bis vier Wochen einen unansehnlichen Anblick.
Auch sind bisher keine Luftverbesserungspräparate bekannt, welche eine wirkungsvolle Geruchsvertilgung innerhalb höchstens ein bis zehn und vorzugsweise ein bis fünf Minuten bei einer Verdampfung von etwa 30 bis 400 mg täglich aus einer Präparatemenge von 100 g bewerkstelligen, und dies nicht nur während ein bis zwei Wochen, sondern langdauernd, d. h. während 60 bis 90 Tagen oder noch länger.
Es ist ein Hauptzweck dieser Erfindung, Luftverbesserungspräparate mit verdampfendem Wirkstoff zu finden, welche eine solche langdauernde Wirkung besitzen.
Die vorliegende Anmeldung betrifft nun ein festes, formbeständiges Luftverbesserungspräparat mit in einem Trägermaterial verteilter allmählich verdampfender Wirkstoffkomponente, enthaltend: [A] einen Gelbildner, bestehend aus pyrogenem Siliciumdioxid, einer Metallseife, einem organischen hydrophoben Bentonitderivat oder einem Polymerharz, enthaltendes Paraffin als Trägermaterial, und [B] mindestens 5 % eines Geruchsvertilgers, dessen Höchstmenge in dem Gel [A] homogen verteilbar ist und 70% nicht übersteigt, dadurch gekennzeichnet, dass der Anteil an Gelbildner [A] 30 bis 90Gc beträgt und der Geruchsvertilger [B] aus olefinisch ungesättigten Alkoholen, welche bei 25 C einen Dampfdruck im Bereich von 0,001 bis 3,5 Torr aufweisen, ausgewählt ist,
wobei die eingesetzte Menge von [B] im Gel [A] homogen verteilbar ist und alle Prozentangaben auf das Gesamtgewicht [A] + [B] bezogen sind.
Diese Präparate weisen eine gute Festigkeit sowie Formstabilität auf und eignen sich besonders gut zur fortdauernden Beseitigung von unerwünschten Gerüchen in Räumen, insbesondere Wohnräumen.
Weiter betrifft die vorliegende Erfindung ein Luftverbesserungspräparat, das [C] 0,01 bis 65%, bezogen auf das Gesamtgewicht der Bestandteile [A] bis [C], eines Riechstoffes, der nicht der Definition der Geruchsvertilger [B] entspricht, dessen Dampfdruck bei 25" C im Bereich von 0,001 bis 5 Torr liegt und dessen eingesetzte Menge in [A] + [B] homogen verteilbar ist.
Das erfindungsgemässe Präparat kann beliebige Form aufweisen, z. B. die Form einer Platte, einer Stange, eines Prismas, eines Zylinders, insbesondere auch eines Hohlzylinders, oder eines anderen profilierten Körpers. Ebenfalls kann es geformte dekorative Artikel oder Überzüge bilden.
Die Festigkeit des erfindungsgemässen Präparates ermöglicht das Formen, das Schneiden, die Granulierung und andere Verfahren zur Herstellung von Artikeln gewünschter Form.
Die Festigkeit oder Härte eines erfindungsgemässen Präparates, gemessen nach ASTM-D 1321-61T, beläuft sich auf 1,5 bis ca. 15 mm, vorzugsweise 1,5 bis 7,5 mm. Besonders bevorzugt sind diejenigen Präparate, deren Härte zwischen 3,5 und 6 mm liegt.
Die erfindungsgemässen Präparate sind formbeständig.
Das heisst, sie behalten bei Zimmertemperatur (15 bis 35 C) und Atmosphärendruck während ihrer ganzen Wirkungsdauer dieselbe Form. Dies ist vom ästhetischen Standpunkt aus gesehen ein wichtiger Vorteil, denn solche Präparate sind attraktiver für den Benutzer als diejenigen bekannten, welche sich während der Abgabe der Wirkstoffe verformen, in sich zusammenschrumpfen oder zerfallen.
Die Schmelztemperatur der erfindungsgemässen Präparate soll zweckmässig zwischen 54 und 60 C und vorzugsweise zwischen 55 und 570 C liegen.
In der vorliegenden Anmeldung umfasst der Begriff Luftverbesserungspräparat eine Zusammensetzung, welche fähig ist, die in einem Raum befindliche Luft durch Beseitigung unangenehmer Gerüche aufzufrischen.
Das erfindungsgemässe Präparat stellt eine Verdampfervorrichtung dar, welche die flüchtigen Wirkstoffkomponenten [B] und [C] allmählich über eine ziemlich lange Zeitdauer abgibt.
Die erfindungsgemässen Präparate enthalten, wie gesagt, 30 bis 5 % und vorzugsweise 30 bis 65 %, bezogen auf das Gesamtgewicht der obengenannten Bestandteile [A] bis [C] einschliesslich, eines durch pyrogenes Siliciumdioxid, Aluminiumseife, organisches hydrophobes Bentonitderivat oder Polymerharz gelierten, hydrophoben Paraffins als Trägermaterial.
Die verwendbaren Paraffine sind Kohlenwasserstoffe, deren Schmelzpunkt im Bereich von 40 bis 75" C liegt, wie z. B. die Paraffine nach Pharmacopoea Helvetica VI, Seite 1109.
Sie können aus eigentlichem Paraffinwachs, Isoparaffin, Ceresin, Mikrowachs, Tankwachsen und dergleichen oder Mischungen solcher Paraffine bestehen.
Bevorzugt sind die Paraffine, deren Schmelzpunkt bei 55 bis 75" C liegt.
Das Gelieren des Paraffins im flüssigen Zustand durch Verwendung mindestens eines entsprechenden hydrophoben Gelierungsmittels ist ein wichtiges Merkmal der erfindungsgemässen Präparate.
Versuche haben gezeigt, dass Zusammensetzungen, in welchen das Paraffin nicht im flüssigen Zustand geliert worden ist, zwar feste, formbeständige Festkörper ergeben, welche aber keine zufriedenstellenden Verdampfungsraten der Wirkstoffe aufweisen. Solche Präparate zeigen nämlich eine unregelmässige Abgabe der in dem Präparat verteilten flüchtigen Stoffe sowie eine zu kurze Wirkungsdauer.
Wenn das verwendete Gelierungsmittel aus einem pyrogenen Siliciumdioxyd besteht, beträgt die Gesamtmenge an Gelbildner 1 bis 5 %, bezogen auf das Gesamtgewicht der Bestandteile [A] und [C] einschliesslich.
Als pyrogenes Siliziumdioxyd sind für die Gelbildung mit Paraffinwachs koagulierte Siliziumdioxyde mit vorzugsweise kugelförmigen Teilchen, deren mittlerer Durchmesser im Bereich von 5 bis 50, vorzugsweise 5 bis 20 Millimikron liegt, besonders geeignet, z. B. die Produkte, welche unter dem Namen ROSILE durch Degussa sowie unter dem Namen CAB-O-SILs durch die Firma Cabot hergestellt werden.
In den weiter unten gegebenen Beispielen mit pyrogenem Siliziumdioxyd als Gelbildner wurde stets koaguliertes Siliziumdioxyd mit kugelförmigen Teilchen, deren mittlere Grösse ca. 12 Millimikron aufweist, verwendet.
Besteht das verwendete Gelierungsmittel aus einer Aluminiumseife oder aus einer Mischung verschiedener Aluminiumseifen, so soll dessen Gesamtmenge an Gelbildner 2 bis 8 Gc, bezogen auf das Gesamtgewicht der Bestandteile [A] bis [C] einschliesslich, betragen.
Als gelierende Metallseifen sind für die Gelbildung mit Paraffinwachs die Aluminiummono-, -di- und -tristearate mit einem Gehalt von 0 bis 25 % an freier Stearinsäure besonders geeignet.
Besonders bevorzugt aber ist ein Aluminiumdistearat mit einem Gehalt von 3 bis 7 % freier Stearinsäure.
In den weiter unten gegebenen Beispielen mit einer Aluminiumseife als Gelbildner wurden stets Aluminiumstearate verwendet.
Als organische Bentonitderivate sind für die Gelbildung mit Paraffinwachs die Produkte geeignet, welche durch Austausch der mineralischen Kationen eines Tons mit organisch substituierten Ammonium-Kationen erhalten worden sind.
Solche sind vor allem mono- bis tetra-alkylierte Ammo niumsalze des Montmorillonits, z. B. das Octadecylammoniumoder das Dimethyloctadecylammoniumsalz.
In den weiter unten gegebenen Beispielen mit einem Bentonitderivat als Gelbildner wurde stets Bentone 38 der National Lead Company verwendet, das aus einem Dimethyldialkylmontmorillonitammoniumsalz, in welchem jeder der beiden Alkylreste durchschnittlich 17 Kohlenstoffatome aufweist, und einem Magnesiummontmorillonit besteht.
Besteht das verwendete Gelierungsmittel aus einem Polymerharz, so soll die Gesamtmenge an Gelbildner 5 bis 20 %, vorzugsweise 12 bis 150/0, bezogen auf das Gesamtgewicht der Bestandteile [A] bis [C] einschliesslich, betragen.
Polymerharze, welche in den erfindungsgemässen Präparaten als Gelierungsmittel verwendet werden können, sind z. B. Polymerisate oder Mischpolymerisate der Vinylverbindungen, wie Acetat, Propionat, Butyrat, Oxyde, Formal, Acetal, Butyral, Chlorid, und/oder der Vinyliden-Verbindungen und/oder der Alkene, wie Äthylen, Propylen, Butylen mit einem Molekulargewicht, das höher als 1000 ist.
In den erfindungsgemässen Präparaten sind die Copolymere aus Essigsäurevinylester und Äthylen mit einem Gehalt von 25 bis 35 Gew. %, vorzugsweise von 27 bis 29 Gew. %, Vinylacetateinheiten sowie Polyäthylene und nachchlorierte Polyvinylchloride mit einem Chlorgehalt von 50 bis 75% besonders geeignet.
In den weiter unten gegebenen Beispielen mit einem Polymerharz als Gelbildner wurden ein Copolymer aus Essigsäurevinylester und Äthylen mit 27 bis 29 Gew. % Vinylacetateinheiten sowie ein Polyäthylen und ein nachchloriertes Polyvinylchlorid verwendet.
In den aus Paraffin und Gelbildner erhaltenen Gelen müssen sowohl der Geruchsvertilger als auch ein gegebenenfalls vorhandener Riechstoff homogen dispergierbar sein.
In bevorzugten erfindungsgemässen Präparaten sind 15 bis 50%, bezogen auf das Gesamtgewicht der obengenannten Bestandteile [A] bis [C] einschliesslich, mindestens eines Geruchsvertilgers enthalten, dessen Dampfdruck bei 25" C im Bereich von 0,03 bis 1 Torr, vorzugsweise bis 0,5 Torr, liegt.
Unter dem Begriff Geruchsvertilger sind Verbindungen zu verstehen, welche als in geringen Konzentrationen in der Luft vorhandener Dampf mit den meisten chemischen Verbindungen, die schlechte Gerüche verursachen, reagieren und diese in neue Verbindungen, welche keinen merklichen Geruch besitzen, umwandeln. Solche Geruchsvertilger reagieren z. B. mit stickstoffhaltigen oder schwefelhaltigen Gruppen in den Molekülen flüchtiger Stoffe, welche in der Luft von Küchen, Badezimmern, Krankenzimmern, mit Rauch gefüllten Wohnzimmern und dergleichen vorhanden sind. Die hierbei auftretenden chemischen Reaktionen müssen irreversibel und möglichst schnell vonstatten gehen, um alle in einem Raum vorhandenen schlechten Gerüche innerhalb von ein bis zehn Minuten zu beseitigen.
Weiter dürfen die verwendeten Geruchsvertilger sowie ihre Reaktionsprodukte nicht toxisch sein und die Augen und Lunge nicht reizen.

Catechol, Pyrogallol, Resorcin, Phloroglucin, Hydrochinon, 3-Phenylisocumaron, Tocopherol, p-Aminophenol, 2,6-ditert.-Butylphenol, Cresole, Butylhydroxyanisole, Gallussäureester, Butylhydroxyltoluole, p-Octylphenol, p-Nonylphenol, p-tert.-Butylphenol, 2,6-ditert.-Amylphenol, 2,4,6 Trimethylphenol, 2,4,6-tritert.-Butylphenol, 2,3,4,5-Tetramethylphenol, Pentamethylohenol und Benzoesäureparahydroxymethylester.
Die erfindungsgemässen Präparate werden vorzugsweise hergestellt, indem man
1. die Gesamtmenge an Geliermittel wie Aluminiumseife und flüssigem Paraffin unter dauerndem Rühren regelmässig erhitzt, bis man eine homogene gelierte Masse erhält, deren Temperatur zwischen 70 und 1500 C liegt;
2. das erhaltene Gel unter fortlaufendem Rühren bis 90" C abkühlt; alsdann
3. die Gesamtmenge an Geruchsvertilger und Riechstoff zugibt und schliesslich
4. das erhaltene flüssige Gel bei ca. 80" C in Formen giesst oder in einem Granulierungsapparat zu Granulat verarbeitet.
Bei Abkühlung der erfindungsgemässen Präparate erhält man ein festes Präparat; dieses Präparat kann leicht aus den Formen entfernt werden und dann in einer für die Geruchsvertilger- und Riechstoffkomponenten undurchlässigen Hülle verpackt werden, welche vor der Inbetriebnahme vom Benutzer entfernt oder geöffnet werden muss.
Die Form kann auch, zusammen mit einem nach dem Giessvorgang angebrachten Deckel, die undurchlässige Hülle bilden.
Sie wird vor der Inbetriebnahme vom Benutzer ganz oder teilweise entfernt, beispielsweise bis auf den erwähnten Deckel, der nun als Unterlage für das Präparat benützt werden kann.
In diesem Fall bildet die das Präparat enthaltende, für den Geruchsvertilger und den Riechstoff undurchlässige Form zusammen mit einem Deckel oder einer hermetisch geschlossenen Schutzfolie das fertige Produkt. Die Schutzhülle kann insbesondere so vorgesehen sein, dass sie auf Wunsch des Benutzers entfernt und dann wieder angebracht werden kann, um die Verdampfung des Wirkstoffs in die Umgebung zunächst zu gestatten und dann wieder zu unterbrechen.
Die erfindungsgemässen Präparate können auch als Granulate verwendet werden. Vorzugsweise beträgt der durchschnittliche Granulatdurchmesser 0,5 bis 3 mm. Die Granulate können in einer für die Geruchs- und Riechstoffkomponenten durchlässigen Hülle verpackt werden und der so erhaltene Beutel alsdann in einer undurchlässigen Hülle untergebracht werden.
Die erfindungsgemässen Präparate stellen für den Benutzer attraktive, formbeständige Luftverbesserungspräparate dar; sie ermöglichen eine langdauernde regelmässige Abgabe des Geruchsvertilgers in genügender Menge und bleiben mindestens zwei bis drei Monate lang wirksam.
Wie in folgenden Vergleichsversuchen und Beispielen gezeigt wird, kann, wenn ein 30 bis 100 g wiegendes erfindungsgemässes Präparat, das in einem Raum von 30 bis 50 m3, in welchem ein unerwünschter Geruch herrscht, aufgestellt wird, eine totale Beseitigung dieses Geruchs innerhalb ein bis zehn Minuten bzw. ein bis fünf Minuten festgestellt werden.
Je 30 bis 100 g der erfindungsgemässen Präparate geben dabei während der ersten Woche eine tägliche durchschnittliche Menge [a] von ca. 50 bis 350 mg, während insgesamt mindestens sieben bis acht Wochen eine tägliche durchschnittliche Menge 8ss] von ca. 20 bis 600 mg und während insgesamt 13 Wochen eine tägliche durchschnittliche Menge [y] von ca. 30 bis 200 mg an flüchtigen Stoffen ab.
Die aus den erfindungsgemässen Präparaten verdampften Gesamtmengen an flüchtigen Stoffen [B] + [C] sowie die Verdampfungsgeschwindigkeit und die Wirkungsdauer sind besonders günstig, wenn die Regelmässigkeitskoeffizienten [a]/lss] und GO]l[yl zwischen 1 und 3, vorzugsweise zwischen 1 und 2, liegen.
Ganz besonders günstig sind die Verdampfungsraten, wenn der Wert des Quotienten [a]/Ess]: Lss]/[y] zwischen 1 und 2,5, vorzugsweise zwischen 1 und 2, liegt. Je näher bei 1 diese verschiedenen Quotienten liegen, desto gleichmässiger verläuft die Verdampfung. Bevorzugt sind diejenigen Präparate, welche mindestens drei Monate lang täglich mindestens 100 mg flüchtiger Stoffe abgeben.
In den nachfolgenden Versuchen und Ausführungsbeispielen bedeuten die Mengenangaben Gewichtsteile.

Dem flüssigen Paraffin wurde bei 95" C das pulverförmige Aluminiumdistearat zugegeben, und diese Mischung wurde dann unter dauerndem Rühren bis auf 115" C erwärmt und während 15 Minuten bei dieser Temperatur geliert.
Das erhaltene Gel wurde dann schnell mit Hilfe eines Wasserbades unter Rühren abgekühlt; sobald das Gel eine Temperatur von 90" C erreicht hatte, wurde der flüssige Fumarsäuredialkylester hinzugegeben. Sobald die Mischung auf 80" C abgekühlt war, wurde sie in zylindrische Formen aus rostfreiem Stahl gegossen.
Sobald die Temperatur der in die Formen gegossenen Massen durch Kontakt mit der Umgebungsluft auf etwa 20 C abgesunken war, wurden die hohlen zylindrischen Blöcke aus den Formen entfernt.

The present invention relates to solid, dimensionally stable air freshening preparations with active ingredient which evaporates for a long time and almost constantly for the permanent fixation of undesirable odors in rooms. The subject matter of the main patent No. 582003 is not included in the subject matter of the present invention.
Solid, dimensionally stable air freshening preparations in the form of solid solutions of volatile menthadienes in hard polymers such as polyethylene or ethyl cellulose are already known from US Pat. No. 2,865,806. However, such air freshening preparations do not have sufficient strength, no long-term dimensional stability and no satisfactory effectiveness. Although they enable some undesirable odors to be covered, they do not actually eradicate them. Since they disintegrate or crumble as the release of the active ingredient increases, they are unsightly to look at after two to four weeks.
Also, no air freshener preparations have been known to date which effectively eliminate odors within a maximum of one to ten and preferably one to five minutes with an evaporation of about 30 to 400 mg daily from a preparation amount of 100 g, and not only for one to two weeks, but long-term, d. H. for 60 to 90 days or even longer.
It is a primary purpose of this invention to find vaporizing air freshener preparations which have such a long-term effect.
The present application relates to a solid, dimensionally stable air freshening preparation with gradually evaporating active ingredient component distributed in a carrier material, containing: [A] a gelling agent consisting of fumed silicon dioxide, a metal soap, an organic hydrophobic bentonite derivative or a polymer resin, containing paraffin as carrier material, and [ B] at least 5% of an odor suppressant, the maximum amount of which can be distributed homogeneously in the gel [A] and does not exceed 70%, characterized in that the proportion of gel former [A] is 30 to 90Gc and the odor suppressant [B] consists of olefinically unsaturated alcohols which have a vapor pressure in the range from 0.001 to 3.5 Torr at 25 C, is selected,
The amount of [B] used in the gel [A] can be distributed homogeneously and all percentages are based on the total weight [A] + [B].
These preparations have good strength and dimensional stability and are particularly suitable for the permanent elimination of undesirable odors in rooms, especially living rooms.
The present invention further relates to an air freshening preparation which [C] 0.01 to 65%, based on the total weight of the components [A] to [C], of a fragrance which does not correspond to the definition of odor-absorbing agents [B], its vapor pressure at 25 "C is in the range from 0.001 to 5 Torr and the amount used can be homogeneously distributed in [A] + [B].
The preparation according to the invention can have any shape, e.g. B. the shape of a plate, a rod, a prism, a cylinder, in particular a hollow cylinder, or another profiled body. It can also form molded decorative articles or coatings.
The strength of the preparation according to the invention enables molding, cutting, granulation and other processes for the production of articles of the desired shape.
The strength or hardness of a preparation according to the invention, measured according to ASTM-D 1321-61T, is 1.5 to about 15 mm, preferably 1.5 to 7.5 mm. Those preparations whose hardness is between 3.5 and 6 mm are particularly preferred.
The preparations according to the invention are dimensionally stable.
This means that they keep the same shape at room temperature (15 to 35 C) and atmospheric pressure throughout their duration of action. This is an important advantage from an aesthetic point of view, because such preparations are more attractive to the user than those known which deform, shrink or disintegrate during the delivery of the active ingredients.
The melting temperature of the preparations according to the invention should expediently be between 54 and 60 C and preferably between 55 and 570 C.
In the present application, the term air freshening preparation includes a composition which is capable of freshening up the air in a room by removing unpleasant odors.
The preparation according to the invention represents a vaporizer device which gradually releases the volatile active ingredient components [B] and [C] over a fairly long period of time.
The preparations according to the invention contain, as said, 30 to 5% and preferably 30 to 65%, based on the total weight of the above-mentioned constituents [A] to [C] including, of a hydrophobic gelled by fumed silicon dioxide, aluminum soap, organic, hydrophobic bentonite derivative or polymer resin Paraffins as a carrier material.
The paraffins that can be used are hydrocarbons whose melting point is in the range from 40 to 75 ° C., such as, for example, the paraffins according to Pharmacopoeia Helvetica VI, page 1109.
They can consist of actual paraffin wax, isoparaffin, ceresin, microwax, tank waxes and the like, or mixtures of such paraffins.
Paraffins with a melting point of 55 to 75 ° C. are preferred.
The gelling of the paraffin in the liquid state by using at least one corresponding hydrophobic gelling agent is an important feature of the preparations according to the invention.
Tests have shown that compositions in which the paraffin has not been gelled in the liquid state produce solid, dimensionally stable solids, but which do not have satisfactory rates of evaporation of the active ingredients. Such preparations namely show an irregular release of the volatile substances distributed in the preparation as well as a too short duration of action.
If the gelling agent used consists of a pyrogenic silicon dioxide, the total amount of gelling agent is 1 to 5%, based on the total weight of the components [A] and [C] inclusive.
As pyrogenic silicon dioxide for gel formation with paraffin wax coagulated silicon dioxides with preferably spherical particles whose mean diameter is in the range of 5 to 50, preferably 5 to 20 millimicrons, are particularly suitable, for. B. the products which are manufactured under the name ROSILE by Degussa and under the name CAB-O-SILs by the Cabot company.
In the examples given below with pyrogenic silicon dioxide as the gel former, coagulated silicon dioxide with spherical particles with an average size of approximately 12 millimicrons was used.
If the gelling agent used consists of an aluminum soap or a mixture of different aluminum soaps, its total amount of gelling agent should be 2 to 8 Gc, based on the total weight of components [A] to [C] inclusive.
Aluminum mono-, di- and tristearates with a content of 0 to 25% of free stearic acid are particularly suitable as gelling metal soaps for gel formation with paraffin wax.
However, an aluminum distearate with a content of 3 to 7% free stearic acid is particularly preferred.
In the examples given below with an aluminum soap as the gel former, aluminum stearates were always used.
Suitable organic bentonite derivatives for gel formation with paraffin wax are those products which have been obtained by exchanging the mineral cations of a clay with organically substituted ammonium cations.
Such are especially mono- to tetra-alkylated Ammo nium salts of montmorillonite, eg. B. the octadecylammonium or the dimethyloctadecylammonium salt.
In the examples given below with a bentonite derivative as gel former, Bentone 38 from the National Lead Company was always used, which consists of a dimethyldialkylmontmorillonite ammonium salt, in which each of the two alkyl radicals has an average of 17 carbon atoms, and a magnesium montmorillonite.
If the gelling agent used consists of a polymer resin, the total amount of gelling agent should be 5 to 20%, preferably 12 to 150/0, based on the total weight of components [A] to [C] inclusive.
Polymer resins which can be used as gelling agents in the preparations according to the invention are, for. B. polymers or copolymers of vinyl compounds such as acetate, propionate, butyrate, oxides, formal, acetal, butyral, chloride, and / or vinylidene compounds and / or alkenes such as ethylene, propylene, butylene with a molecular weight that is higher than 1000.
In the preparations according to the invention, the copolymers of vinyl acetate and ethylene with a content of 25 to 35% by weight, preferably 27 to 29% by weight, vinyl acetate units and also polyethylene and post-chlorinated polyvinyl chlorides with a chlorine content of 50 to 75% are particularly suitable.
In the examples given below with a polymer resin as the gel former, a copolymer of vinyl acetate and ethylene with 27 to 29% by weight of vinyl acetate units and a polyethylene and a post-chlorinated polyvinyl chloride were used.
In the gels obtained from paraffin and gel former, both the odor suppressant and any odoriferous substance that may be present must be homogeneously dispersible.
Preferred preparations according to the invention contain 15 to 50%, based on the total weight of the above-mentioned constituents [A] to [C] including, at least one odor suppressant whose vapor pressure at 25 "C is in the range from 0.03 to 1 Torr, preferably up to 0 , 5 Torr.
The term odor-absorbing compounds is to be understood as meaning compounds which, as vapor present in low concentrations in the air, react with most chemical compounds that cause bad odors and convert them into new compounds that have no noticeable odor. Such odor-absorbing agents react z. B. with nitrogen-containing or sulfur-containing groups in the molecules of volatile substances which are present in the air of kitchens, bathrooms, sickrooms, smoke-filled living rooms and the like. The chemical reactions that occur here must be irreversible and take place as quickly as possible in order to eliminate all bad odors in a room within one to ten minutes.
Furthermore, the odor destroyers used and their reaction products must not be toxic and not irritate the eyes or lungs.

2. The gel obtained cools down to 90 "C with continuous stirring; then
3. Adds the total amount of odor-eliminating agent and odoriferous substance and finally
4. Pour the resulting liquid gel into molds at approx. 80 "C or process it into granules in a granulating device.
When the preparations according to the invention cool down, a solid preparation is obtained; this preparation can easily be removed from the molds and then packaged in an envelope which is impermeable to the odor-absorbing and odorant components and which must be removed or opened by the user prior to use.
The mold, together with a cover attached after the casting process, can also form the impermeable shell.
It is completely or partially removed by the user prior to commissioning, for example except for the cover mentioned, which can now be used as a base for the preparation.
In this case, the form containing the preparation and impermeable to the odor suppressant and the odorous substance, together with a cover or a hermetically sealed protective film, forms the finished product. The protective cover can in particular be provided in such a way that it can be removed and then reattached at the request of the user in order to first allow the evaporation of the active substance into the environment and then to interrupt it again.
The preparations according to the invention can also be used as granules. The average granulate diameter is preferably 0.5 to 3 mm. The granules can be packaged in an envelope that is permeable to the odor and fragrance components and the pouch obtained in this way can then be accommodated in an impermeable envelope.
The preparations according to the invention represent air freshening preparations which are attractive to the user and retain their shape; they enable a long-term, regular release of the odor eliminator in sufficient quantities and remain effective for at least two to three months.
As will be shown in the following comparative experiments and examples, if a 30 to 100 g preparation according to the invention is placed in a room of 30 to 50 m3 in which there is an undesirable odor, a total elimination of this odor within one to ten Minutes or one to five minutes.
Each 30 to 100 g of the preparations according to the invention give a daily average amount [a] of approx. 50 to 350 mg during the first week, and a daily average amount of approx. 20 to 600 mg for a total of at least seven to eight weeks a daily average amount [y] of approx. 30 to 200 mg of volatile substances for a total of 13 weeks.
The total amounts of volatile substances [B] + [C] evaporated from the preparations according to the invention as well as the evaporation rate and the duration of action are particularly favorable if the regularity coefficients [a] / lss] and GO] l [yl between 1 and 3, preferably between 1 and 2, lie.
The evaporation rates are particularly favorable when the value of the quotient [a] / Ess]: Lss] / [y] is between 1 and 2.5, preferably between 1 and 2. The closer these different quotients are to 1, the more evenly the evaporation proceeds. Those preparations which release at least 100 mg of volatile substances daily for at least three months are preferred.
In the experiments and working examples below, the quantitative data are parts by weight.
