Organoleptic use of cyclohexenyl-alpha-alkyl acrolein derivatives

BACKGROUND OF THE INVENTION
The instant invention provides the cyclohexenyl-alpha-alkyl acrolein derivatives defined according to the generic structure: ##STR3## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or methyl with the proviso that one, two or three of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent methyl; wherein R.sub.5 represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R.sub.5, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond; and uses thereof for their organoleptic properties in consumable materials.
Materials which provide powerful, green, cumin-like, spicy, cinnamon-like, natural orris, floral (violet-like), animalic, musky, floral (lily/lilac), ionone-like, orris-like, burnt orris, pungent fresh green, woody and "tropical rain forest" aromas are highly desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute such desired nuances to perfumery compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.
By the same token, materials which can provide powerful, spicy, cinnamon, cumin-like, green and dandelion leaf-like aroma and taste nuances are highly desirable in the art of flavorings for foodstuffs, toothpastes, chewing gums, chewing tobaccos and medicinal products. Many of the natural materials which provide such flavor notes and contribute such desired nuances to flavoring compositions are high in costs, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.
Hay-clover-like, sweet, rich-tobacco, floral, fruity, green and earthy aroma and taste nuances are highly desirable for many uses in flavoring smoking tobacco compositions and smoking tobacco article components.
Arctander "Perfume and Flavor Chemicals (Aroma Chemicals)", Volume II, at monograph 2896, discloses that tetrahydro cinnamic aldehyde having the structure: ##STR4## has a powerful, sweet-green, leafy, delicately creamy odor. Arctander further discloses:
"The title aldehyde, commonly referred to under the title name, was developed many years ago in continuation of the search for interesting aldehydes from the Claisen reaction, by which Cinnamic aldehyde had been produced. It was also based upon a new method of obtaining Cyclohexene aldehydes and homologues of same.
The subject material has found some application in perfumery, and so has the Cyclohexene carboxaldehyde from which it is made. The parent cyclic aldehyde has a powerful green-leafy odor, and it was interesting to see what type odor could be obtained by the Claisen condensation.
Although rarely offered under its proper chemical name, this material is still used in various perfume specialties and bases for its refreshing, green note, sometimes useful in Citrus compositions, but also used in Chypres, Fougeres, etc. in combination with Oakmoss, Lavender, etc.
It is produced from Acrolein and Butadiene to make Cyclohex-3-enealdehyde. By condensation (Claisen) with Acetaldehyde the title material is obtained."
Arctander, at monograph 2896, refers to French Pat. No. 672025 published on Dec. 21, 1929. In said French Pat. No. 672025, the Diels-Alder reactions of acrolein derivatives with conjugated dienes to produce cyclohexene carboxaldehydes are disclosed. Thus, for example, the reaction: ##STR5## is disclosed to produce a perfumery compound. Furthermore, French Pat. No. 672025 discloses that the resulting carboxaldehydes can be further reacted with ketones to produce irone-type derivatives at page 3, lines 75-82 and at page 4, lines 1-5.
Neither the French Pat. No. 672025 nor the Arctander reference discloses or infers that the compounds defined according to the structure: ##STR6## has desirable organoleptic properties which are unexpected, unobvious and advantageous.
Arctander "Perfume and Flavor Chemicals (Aroma Chemicals)", Volume I, at monograph 761 discloses the use of iso-Cyclocitral which is a mixture of compounds having the structures: ##STR7## for its organoleptic properties thusly: "Powerful, and diffusive, foilage-green, "dark"-weedy and dry odor, sometimes described as "Flower-shop odor". The earthy and wet-green notes are quite natural in high dilution and resemble the odor of stems from plants and flowers fresh from the soil.
Finds use in perfume compositions where it blends excellently with Oakmoss products (compensates for sweetness and lifts the topnote), with Ionones (freshness), Geranium and Galbanum (enhances the green and "vegetable" notes), etc.
On account of its modest cost it also finds its way into masking odors for industrial purposes. Its power compensates for its cost (usually slightly less than Citral) for such purposes.
Produced by a Diels-Alder type condensation of 2-Methyl-2,4-pentadiene and Crotonaldehyde. The reaction product is a mixture of isomers commercially called iso-Cyclocitral (after rectification)".
At monographs 762 and 763, Arctander describes alpha-Cyclocitrylidene Acetaldehyde and beta-Cyclocitrylidene Acetaldehyde having the structures, respectively: ##STR8## thusly:
762: alpha-Cyclocitrylidene Acetaldehyde
"Mild floral-woody, somewhat oily-herbaceous odor, remotely reminiscent of Rose with similarity to the odor of hydrogenated Ionones.
Suggested for use in perfume compositions. It brings a certain amount of floral lift to Rose compositions, and performs fairly well even in soap. However, the cost of the rarely offered and never readily available lots are rather discouraging to the perfumer, and it is most conceivable that this material can be left out of the perfumer's library without any great loss.
Produced from alpha-Cyclocitral and Acetaldehyde by condensation."
763: beta-Cyclocitrylidene Acetaldehyde
"Sweet-woody, rather heavy odor, resembling that of beta-Ionone. More fruity than really floral, but not as tenacious as the Ionone.
Suggested for use in perfume compositions, but since it does not offer any new or unusual odor characteristics, and it cannot be produced in economical competition to beta-Ionone, there is little or no chance that it will ever become a standard shelf ingredient for the perfumer.
Produced from beta-Cyclocitral and Acetaldehyde by condensation."
U.S. Pat. No. 3,031,507 discloses the use in perfumery of cyclohexylcrotonaldehyde having the structure: ##STR9##
U.S. Pat. No. 3,313,843 discloses the use of cinnamaldehyde derivatives having the structure: ##STR10## wherein R is hydrogen or methyl as intermediates for preparing other compounds.
Nothing in the prior art, above cited, or any other prior art infers or discloses the compounds having the generic structure: ##STR11## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or methyl with the proviso that one, two or three of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent methyl; wherein R.sub.5 represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R.sub.5, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond.
Nothing in the prior art discloses that such compounds having the structure: ##STR12## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or methyl with the proviso that one, two or three of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent methyl; wherein R.sub.5 represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R.sub.5, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond; has such unexpected, unobvious and advantageous organoleptic properties.

Referring to FIGS. 14 and 15, which show the apparatus for preparing scented polymers such as polyethylene, a quantity of thermoplastic polymer having a melting point of 220.degree.-250.degree. F. is placed in a container 512 as illustrated in FIGS. 14 and 15. 25 Pounds of a perfume formulation containing at least one of the cyclohexenyl-alpha-alkyl acrelein derivatives of our invention is then quickly added to the liquified molten polymer in container 512, the lid 528 is put in place and the agitating means 573 are actuated. The temperature is maintained at about 225.degree. F. and the mixing is continued for about 5-15 minutes. The valve "V" is then opened to allow flow of the molten thermoplastic polymer (e.g., polyethylene) enriched with a scent-imparting substance containing at least one of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention, to exit through orifices 534. The liquid falling through orifices 534 solidifies almost instantaneously upon impact of the moving cooled conveyor 538. Thermoplastic polymer (e.g., polyethylene) beads or pellets 544 having a pronounced scent as described in the examples, infra resulting from the composition containing one of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention are thus formed. Analysis demonstrates that the pellets contain about 25% of a scent-imparting material containing one of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention so that almost no lost is in the scenting substance occur. The pellets are used as set forth, infra. The conveyor belt 538 is driven by rollers 540 and 542 with cooling apparatus 550 next to roller 540. The tank 512 is heated with heating elements 512A which are energized using an electric energy source evolved via wires 524/514 and 526/522. The solidified pellets are collected in container 546 for a subsequent utilization as set forth in the examples, infra.

The cyclohexenyl-alpha-alkyl acrolein derivatives of our invention can be prepared according to one of two techniques. The first technique involve first providing a methyl-substituted cyclohexene carboxaldehyde having the structure: ##STR59## for example, by means of:
(a) Diels-Alder reaction of a conjugated diene having the structure: ##STR60## with an acrolein derivative having the structure: ##STR61## according to the reaction: ##STR62## and then reacting the cyclohexene carboxaldehyde having the structure: ##STR63## with propionaldehyde or butyraldehyde defined according to the structure: ##STR64## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or methyl with the proviso that one, two or three of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent methyl; wherein R.sub.5 represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R.sub.5, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond; or
(b) Carrying out a Vilsmeier Formulation according to the procedure taught in Chem. Communications, October 1979, pages 799-801 (article by Dauphin, "Vilsmeier Formulation of Limonene. The new method for synthesis of alpha-Atlantone"), according to the reactions: ##STR65## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or methyl with the proviso that one, two or three of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent methyl; wherein R.sub.5 represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R.sub.5, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond.
In the first reaction sequence, the Diels-Alder reaction: ##STR66## is carried out in accordance with the procedure of French Pat. No. 672,025 published on Dec. 21, 1929, the disclosure for which is incorporated by reference herein. In addition, the Diels-Alder reaction can be carried out at lower temperatures using Lewis acid catalyst such as stannic chloride, zinc chloride, aluminum diethyl chloride or ethyl aluminum dichloride (e.g., temperatures of 10.degree.-40.degree. C.). The resultant cyclohexene carboxaldehyde defined according to the structure: ##STR67## is then reacted via an aldol condensation reaction with n-propanal or n-butanal having the structure: ##STR68## according to the reaction: ##STR69## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or methyl with the proviso that one, two or three of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent methyl; wherein R.sub.5 represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R.sub.5, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond.
The aldol condensation is carried out at standard aldol condensation reaction conditions using a base such as sodium hydroxide, potassium hydroxide, calcium hydroxide, lithium hydroxide or barium hydroxide (in, for example, a Soxhlet apparatus) at temperatures in the range of from about 10.degree. C. up to about 80.degree. C. in the presence of an inert compatibles such as methyl alcohol or ethyl alcohol. When using a barium hydroxide catalyst, the barium hydroxide is kept in the Soxhlet thimble and the reactants are refluxed at the reflux temperature of the reaction mass. The reaction can be carried out at atmospheric or super atmospheric pressures. At super atmospheric pressures the time for reaction completion is less than the time for reaction completion when carrying out the reaction at atmosphereic pressure in view of the higher temperature of reaction. The mole ratio of aldehyde having the structure: ##STR70## to aldehyde having the structure: ##STR71## is preferably from about 0.5:1 up to about 1:0.5 with a mole ratio of 1:1 being preferred.
At the end of the reaction, the reaction mass is neutralized and the solvent is stripped. The reaction product is then distilled as by fractional distillation in vacuo to yield the desired products defined according to the structure: ##STR72## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or methyl with the proviso that one, two or three of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent methyl; wherein R.sub.5 represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R.sub.5, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond.
The conditions for the Vilsmeier Formulation are the same as those set forth in the Dauphin paper, the disclosure of which is incorporated by reference herein.
The resultant product is a mixture of "cis" and "trans" isomers, to wit: ##STR73## and, in addition, is a mixture of "endo" and "exo" isomers, for example: ##STR74## which represents, respectively, "cis" or "E" exo, exo, exo or endo, endo, endo. The different products can be trapped out using commercial GLC separations, but more practically they can be used in admixture for their collective organoleptic properties as set forth, infra and supra. Both the Vilsmeier Formulation and the foregoing Aldol condensation techniques however, yield products which are primarily "E" isomers, those which are defined according to the structure: ##STR75## in preponderance over the "Z" isomers.
It is noteworthy that the compounds of our invention have several asymmetric carbon atoms which give rise to a vast number of "endo" and "exo" isomers in addition to the "cis" and "trans" isomers. Thusly, the "*" is indicative of the location of the asymmetric carbon atoms in the following structure: ##STR76## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen or methyl with the proviso that one, two or three of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent methyl; wherein R.sub.5 represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R.sub.5, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond.
When the cyclohexnyl-alpha-alkyl acrolein derivatives of our invention are used as food flavor adjuvants, the nature of the co-ingredients included with said cyclohexenyl-alpha-alkyl acrolein derivatives of our invention in formulating the product composition will also serve to alter, modify, augment or enhance the organoleptic characteristics of the ultimate foodstuff treated therewith.
As used herein in regard to flavors, the terms "alter", "modify" and "augment" in their various forms means "supplying or imparting flavor character or note to otherwise bland, relatively tasteless substances or augmenting the existing flavor characteristic where a natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its quality, character or taste".
The term "enhance" is used herein to mean the intensification of a flavor or aroma characteristic or note without the modification of the quality thereof. Thus, "enhancement" of a flavor or aroma means that the enhancement agent does not add any additional flavor note.
As used herein, the term "foodstuff" includes both solid and liquid ingestible material which usually do, but need not, have nutritional value. Thus, foodstuffs include soups, convenience foods, beverages, dairy products, candies, vegetables, cereals, soft drinks, snacks, and the like.
As used herein, the term "medicinal product" includes both solids and liquids which are ingestible, non-toxic materials which have medicinal value such as cough syrups, cough drops, aspirin and chewable medicinal tablets.
The term "chewing gum" is intended to mean a composition which comprises a substantially water insoluble, chewable plastic gum base such as chicle, or substitutes therefor, including jelutong, guttakay, rubber or certain comestible natural or synthetic resins or waxes. Incorporated with the gum base in admixture therwith may be plasticizers or softening agents, e.g., glycerine, and a flavoring composition which incorporates one or more of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention, sweetening agents which may be sugars, including sucrose or dextrose and/or artificial sweeteners such as cyclamates or saccharin. Other optional ingredients may also be present.
Substances suitable for use herein as co-ingredients or flavoring adjuvants are well known in the art for such use, being extensively described in the relevant literature. It is a requirement that any such material be "ingestibly" acceptable and thus non-toxic and otherwise non-deleterious particularly from an organoleptic standpoint whereby the ultimate flavor and/or aroma of the consumable material used is not caused to have unacceptable aroma and taste nuances. Such materials may in general be characterised as flavoring adjuvants or vehicles comprising, broadly, stabilizers, thickeners, surface active agents, conditioners, other flavorants and flavor intensifiers.

The specific flavoring adjuvant selected for use may be either solid or liquid depending upon the desired physical form of the ultimate product, i.e., foodstuff, whether simulated or natural, and should, in any event, (i) be organoleptically compatable with the oxabicyclooctane derivatives and the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention by not covering or spoiling the organoleptic properties (aroma and/or taste) thereof; (ii) be non-reactive with the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention; and (iii) be capable of providing an environment in which the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention can be dispersed or admixed to provide a homogeneous medium. In addition, selection of one or more flavoring adjuvants, as well as the quantities thereof will depend upon the precise organoleptic character desired in the finished product. Thus, in the case of flavoring compositions, ingredient selection will vary in accordance with the foodstuff, chewing gum, medicinal product to toothpaste to which the flavor and/or aroma are to be imparted, modified, altered or enhanced. In contradistinction, in the preparation of solid products, e.g., simulated foodstuffs, ingredients capable of providing normally solid compositions should be selected wuch as various cellulose derivatives.
As will be appreciated by those skilled in the art, the amount of cyclohexenyl-alpha-alkyl acrolein derivatives of our invention employed in a particular instance can vary over a relatively wide range, depending upon the desired organoleptic effects to be achieved. Thus, correspondingly, greater amounts would be necessary in those instances wherein the ultimate food composition to be flavored (e.g., with a spice flavor or a specific black pepper-like-flavor) is relatively bland to the taste whereas relatively minor quantities may suffice for purposes of enhancing the composition merely deficient in natural flavor or aroma.
The primary requirement is that the amount selected be effective, i.e., sufficient to alter, modify or enhance the organoleptic characteristics of the parent composition, whether foodstuff per se, chewing gum per se, medicinal product per se, toothpaste per se, or flavoring composition.
The use of insufficient quantities of cyclohexenyl-alpha-alkyl acrolein derivatives of our invention will, of course, substantially vitiate any possibility of obtaining the desired results while excess quantities prove needlessly costly and in extreme cases may disrupt the flavor-aroma balance, thus proving self-defeating. Accordingly, the terminology "effective amount" and "sufficient amount" is to be accorded a significance in the context of the present invention consistent with the obtention of desired flavoring effects.
Thus, and with respect to ultimate food compositions, chewing gum compositions, medicinal product compositions and toothpaste compositions, it is found that quantities of cyclohexenyl-alpha-alkyl acrolein derivatives of our invention ranging from a small but effective amount, e.g., 0.02 parts per million up to about 500 parts per million based on total composition, are suitable. Concentrations in excess of the maximum quantity stated are not normally recommended since they fail to provide commensurate enhancement of organoleptic properties. In those instances wherein the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention are added to the foodstuff as an integral component of a flavoring composition, it is, of course, essential that the total quantity of flavoring composition employed be sufficient to yield an effective cyclohexenyl-alpha-alkyl acrolein derivatives of our invention concentration in the foodstuff product.
Food flavoring compositions prepared in accordance with the present invention preferably contain the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention in concentrations ranging from about 0.0025% up to about 15% by weight based on the total weight of the said flavoring composition.
The composition described herein can be prepared according to conventional techniques well known as typified by cake batters and fruit drinks and can be formulated by merely admixing the involved ingredients within the proportions stated in a suitable blender to obtain the desired consistency, homogeneity of dispersion, etc. Alternatively, flavoring compositions in the form of particulate solids can be conveniently prepared by mixing the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention with, for example, gum arabic, gum tragacanth, carrageenan and the like, and thereafter spray-drying the resultant mixture whereby to obtain the particular solid product. Pre-prepared flavor mixes in powder form, e.g., a fruit-flavored powder mix, are obtained by mixing the dried solid components, e.g., starch, sugar and the like, and the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention in a dry blender until the requisite degree of uniformity is achieved.
It is presently preferred to combine with the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention, the following adjuvants: Oil of Cubeb; Phellandrene; .beta.-Phellandrene; Oil of Coriander; Oil of Pimento Leaf, Oil of Patchouli; Natural Lemon Oil; Acetaldehyde; .alpha.-Terpineol; Citral; Carvone; Terpinolene; .alpha.-Terpinene; Diphenyl; .alpha.-Fenchyl Alcohol; Cineole; Limonene; Lindalool; Geranyl Acetate; Nootkatone; Neryl Acetate; Heliotropin; Maltol, Vanillin; Ethyl Maltol; Ethyl Vanillin; Anisaldehyde; Alpha Pinene; Beta-Pinene; Beta-Caryophyllene; Dihydrocarveol; Piperonal; Piperine; Chavicine; Piperidine; Oil of Black Pepper; Black Pepper Oleorsin; Capsicum; Oil of Nutmeg; Cardamon Oil; Clove Oil; Separmint Oil; Oil of Peppermint; and C.sub.10 -Terpinyl Ethers as described in application for U.S. patent, Ser. No. 872,937 filed on Jan. 27, 1978, now U.S. Pat. No. 4,131,687 issued on Dec. 26, 1978 (such as fenchyl ethyl ethers), 3-phenyl-3-pentenal dimethyl acetal, cinnamaldehyde, nutmeg oil, dibenzyl ether, eugenol, ethyl vanillin, oil of bitter almond, oil of cinnamon bark, oil of cloves, oil of cardamon, oil of nutmeg, oil of lemon, 2-phenyl-4-pentenal dimethyl acetal, 2-(2'-n-butyl)-4,5-dimethyl thiazoline.
The cyclohexenyl-alpha-alkyl acrolein derivatives of our invention can be used to contribute green, cumin-like, spicy, cinnamon, orris, floral, animalic, musky, lily, lilac, ionone-like, burnt orris, bungent, fresh, green, woody, "tropical rain forest" aroma nuances to perfumes, perfumed articles and colognes. As olfactory agents, the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention can be formulated into or used as components of a "perfume composition" or can be used as components of a "perfumed article" or the perfume composition may be added to perfumed articles.
The term "perfume composition" is used herein to mean a mixture of organic compounds including, for example, alcohols, aldehydes, other than the aldehydes of the instant invention, ketones, nitriles, ethers, lactones, natural essential oils, synthetic essential oils and frequently hydrocarbons which are admixed so that the combined odors of the individual components produce a pleasant or desired fragrance. Such perfume compositions usually contain; (a) the main note or the "bouquet" or foundation-stone of the composition; (b) modifiers which round-off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation, and substances which retard evaporation; and (d) top-notes which are usually low-boiling, fresh-smelling materials.
In perfume compositions, the individual component will contribute its particular olfactory characteristics, but the overall effect of the perfume composition will be the sum of the effects of each of the ingredients. Thus, the individual compounds of our invention, or mixtures thereof, can be used to alter the aroma characteristics of a perfume composition, for example, by highlighting or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention which will be effective in perfume compositions depends on many factors, including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.05% of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention, or even less, can be used to impart an interesting green, cumin-like, spicy, cinnamon, orris, violet-flower-like, animalic, musky, lily, lilac, ionone-like, burnt orris, pungent, fresh, green, woody and "tropical rain forest" aromas to soaps, liquid and solid cationic, anionic, nonionic or zwitterionic detergents, cosmetics, powders, liquid and solid fabric softeners, perfumed polymers per se such as polyethylene and polypropylene, optical brightener compositions and other products. The amount employed can range up to 50% or higher and will depend on considerations of cost, nature of the end product, and the effect desired on the finished product and particular fragrance sought.
The cyclohexenyl-alpha-alkyl acrolein derivatives of our invention can be used alone or in a perfume composition as an olfactory component in detergents and soaps, space odorants and deodorants; perfumes; colognes, toilet waters; bath salts; hair preparations such as lacquers, brilliantines, pomades, and shampoos; cosmetic preparations such as creams, deodorants, hand lotions, and sun screens; powders such as talcs, dusting powders, face powder, and the like. When used as an olfactory component of a perfumed article, as little as 0.01% of one or more of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention will suffice to impart an interesting green, cumin-like, spicy, cinnamon, orris, violet flower, animalic, musky, lily, lilac, ionone-like, burnt orris, bungent, fresh, green, woody, and/or "tropical rain forest" aromas. Generally, no more than 0.5% is required in the perfumed article. Accordingly, the perfumed articles of our invention can contain from about 0.01% up to about 0.5% by weight of the perfumed article of the cyclohexenyl-alpha-alkyl acrolein derivatives of one or more of our invention.
In addition, the perfume composition of our invention can contain a vehicle or carrier for the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention alone or with other ingredients. The vehicle can be a liquid such as an alcohol such as ethanol, a glycol such as propylene glycol, or the like. The carrier can be an absorbent solid such as a gum (e.g., guar gum or xanthan gum or gum arabic) or components for encapsulating the composition such as gelatin (as by coacervation) or a urea formaldehyde prepolymer (to form a urea formaldehyde polymer wall around the liquid perfume center) which can be used to form a capsule wall surrounding the perfume oil.
An additional aspect of our invention provides an organoleptically improved smoking tobacco product and additives therefor including methods of making the same which overcome problems heretofore encountered in the creation or enhancement of specific desired natural tobacco-like notes, particularly hay-clover-like, sweet, rich tobacco, floral, fruity, green, and earthy notes. Such notes, both prior to and on smoking, in both the main stream and the side stream, may now be readily be controlled and maintained at the desired uniform level regardless of variations in the tobacco components of the blend; or the nature of the filter used in conjunction with the smoking tobacco article.
This invention further provides improved tobacco additives and additives for materials used in the fabrication of tobacco articles (particularly smoking tobacco articles) and methods whereby desirable hay-clover-like, sweet, rich tobacco, floral, fruity, green and earthy notes may be imparted to smoking tobacco products and may be readily varied and controlled to produce the desired uniform flavoring characteristics.
In carrying out this aspect of our invention, we add to smoking tobacco materials or a suitable substitute therefor (e.g., dried lettuce leaves) an aroma and flavor additive containing as an active ingredient, one or more of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention.
In addition to the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention, other flavoring and aroma additives may be added to the smoking tobacco material or substituted therefor either separately or in admixture with one or more of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention:

An aroma and flavoring concentrate containing one or more of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention and, if desired, one or more of the above-indicated additional flavoring additives may be added to the smoking tobacco material, to the filter or to the leaf or paper wrapper or to a filter which is part of the smoking article. The smoking tobacco material may be shredded, cured, cased and blended tobacco material or reconstituted tobacco material or tobacco substitutes (e.g., lettuce leaves) or mixtures thereof. The proportions of flavoring additives may be varied in accordance with taste, but insofar as enhancement or the imparting of hay-clover, sweet, rich tobacco, floral, fruity, green and/or earthy notes prior to and on smoking in both the main stream and the side stream, we have found that satisfactory results are obtained if the proportion by weight of the sum total of cyclohexenyl-alpha-alkyl acrolein derivatives of our invention to smoking tobacco material is between 50 ppm and 1500 ppm (0.005%-0.15%) of the active ingredients to the smoking tobacco material. We have further found that satisfactory results are obtained if the proportions by weight of the sum total of cyclohexenyl-alpha-alkyl acrolein derivatives of our invention used to flavoring materials is between 0.05:1 and 0.50:1.
Any convenient method for incorporating the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention may be employed. Thus, the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention, taken alone or along with other flavoring additives may be dissolved in a suitable solvent such as foodgrade ethanol, pentane, diethyl ether and/or other volatile organic solvents, and the resulting solution may either be sprayed on the cured, cased and blended tobacco material; or the tobacco material or filter may be dipped into such solution. Under certain circumstances, a solution of one or more of the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention taken alone or taken further together with other flavoring additives as set forth above, may be applied by means of a suitable applicator such as a brush or roller on the paper or leaf wrapper for the smoking tobacco product, or it may be applied to the filter by either spraying or dipping or coating.
Furthermore, it will be apparent that only a portion of the tobacco or substitute therefor need be treaded, and the thus-treated tobacco may be blended with other tobaccos before the ultimate tobacco product is formed. In such cases, the tobacco treated may have one or more of the cyclohexenyl-alpha-alkyl acrolein derivative of our invention in excess of the amounts or concentrations above indicated so that when blended with other tobaccos, the final product will have the percentage within the indicated range.
While our invention is particularly useful in the manufacture of smoking tobacco such as cigarette tobacco, cigar tobacco and pipe tobacco, other tobacco products formed from sheeted tobacco dust or fines may also be used. As stated, supra, the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention can be incorporated with materials such as filter tip materials, seam paste, packaging materials and the like which are used along with the tobacco to form a product adapted for smoking. Furthermore, the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention can be added to certain tobacco substitutes of natural or synthetic origin (e.g., dried lettuce leaves) and, accordingly, by the term "tobacco" as used throughout this specification is meant any composition intended for human consumption, by smoking or otherwise, whether composed of tobacco plant parts or substitute materials or both.
It will thus be apparent that the cyclohexenyl-alpha-alkyl acrolein derivatives of our invention can be utilized to alter, modify, augment or enhance sensory properties, particularly organoleptic properties, such as flavor(s) and/or fragrance(s) of a wide variety of consumable materials.
The following examples serve to illustrate our invention, and this invention is to be considered restricted thereto only as indicated in the appended claims.
All parts and percentages given herein are by weight unless otherwise specified.

Scented polyethylene pellets having a pronounced aroma as set forth in Table II of Example VII, supra are prepared as follows:
Seventy-five pounds of polyethylene having a melting point of about 220.degree. F. is heated to about 230.degree. F. in a container of the kind illustrated in FIGS. 14 and 15. Twenty-five pounds of one of the perfume compositions of Table II of Example VII is then quickly added to the liquified polyethylene, the lid 528 is put in place and the agitating means 573 are actuated. The temperature is maintained at about 225.degree. F. and the mixing is continued for about 5-15 minutes. The valve "V" is then opened to allow flow of the molten polyethylene enriched with the perfume substance (one of the materials of Table II of Example VII) to exit through the orifices 534. The liquid falling through the orifices 534 solidifies almost instantaneously upon impact with the moving cooled conveyor 538. Polyethylene beads or pellets 544 having pronounced aromas as set forth in Table II of Example VII are thus formed. Analysis demonstrates that the pellets contain about 25% of the perfume substance of Table II of Example VII so that almost no losses in the scenting substance did occur. These pellets may be called "master pellets".
Fifty pounds of the scent containing "master pellets" are then added to one thousand pounds of unscented polyethylene powder and the mass is heated to the liquid state. The liquid is molded into thin sheets of films. The thin sheets of films have pronounced aromas as set forth in Table II of Example VII. The sheets of films are cut into strips 1/4" in width.times.3" in length and placed into apparatus used for air fresheners. On operation of said apparatus as a room air freshener, after 4 minutes, the room has an aesthetically pleasing aroma as set forth in Table II of Example VII.
