(en)This is a continuation of application for U.S. Letters Patent, Ser. No. 335,564 filed on Dec. 29, 1981, now U.S. Pat. No. 4,386,023 issued on May 31, 1983 which is, in turn, a streamline continuation of application for U.S. Letters Patent, Ser. No. 220,621 filed on Dec. 29, 1980 (now abandoned) which, in turn, is a divisional of Application for U.S. Letters Patent, Ser. No. 144,898 filed on Apr. 29, 1980, now U.S. Pat. No. 4,275,251 issued on June 23, 1981.


BACKGROUND OF THE INVENTION
Materials including mixtures of natural products which can provide patchouli-like, green, floral, musty/camphoraceous, rosey, woody, anisic, ionone-like, fruity (banana-like), spicey (cinnamon-like), bitter sweet, milky, petitgrain-like, lavender, bergamot-like, fatty and minty fragrance notes are known in the art of perfumery. Many of the natural materials which provide such fragrances and contribute 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 in natural products.
There is, accordingly, a continuing effort to find synthetic materials which will replace the essential fragrance notes provided by natural essential oils or compositions thereof. Unfortunately, many of these synthetic materials either have the desired nuances only to a relatively small degree or else contribute undesirable or unwanted odor to the compositions. The search for materials which can provide a more refined patchouli-like fragrance, for example, has been difficult and relatively costly in the areas of both natural products and synthetic products.
Thus, Light, et al. in U.S. Pat. No. 3,989,760 provides processes and compositions for altering the flavor and/or aroma of consumable products, including foods, tobacco and perfumes, particularly, perfumes having a patchouli aroma, utilizing as the essential ingredient the organic tricyclic alcohol having the formula: ##STR3##
Buchi, et al, 83 J.Am.Chem.Soc. 927 (1961), shows the production of a material called "patchoulione" which is stated to be octahydro-1,4,9,9-tetramethyl-3a,7-methanoazulen-5-(4H)-one having the structure: ##STR4##
U.S. Pat. No. 3,748,284 issued on July 24, 1973 discloses perhydro derivatives of methanoazulen as having camphoraceous woody fragrances and having the ability to impart this fragrance to perfumed compositions and perfumed articles. The compounds disclosed are:
a. Octahydro-1,4,9,9-tetramethyl-4,7-methanoazulen-3(2H)-one;
b. Octahydro-1,4,9,9-tetramethyl-4,7-methanoazulen-2(3H)-one; and
c. Octahydro-1,4,9,9-tetramethyl-4,7-methanoazulen-8(7H)-one.
Umarani, et al., September/October 1969, P. & E.O.R., 307 discloses two compounds relevant to the instant case:
"isopatchoulinol" having the structure: ##STR5## and "patchouli alcohol" having the structure: ##STR6##
In addition, artificial flavoring agents for foodstuffs have received increasing attention in recent years. In many years, such food flavoring agents have been preferred over natural flavoring agents at least in part due to their diminished cost and their reproducible flavor qualities. For example, natural food flavoring agents such as extracts, concentrates and the like are often subject to wide variations due to changes in the quality, type and treatment of the raw materials. Such variations can be reflected in the end product and result in unfavorable flavor characteristics in said end product. Additionally, the presence of the natural product in the ultimate food may be undesirable because of increased tendency to spoil. This is particularly troublesome in food and food uses where such products as dips, soups, chips, sausages, gravies and the like are apt to be stored prior to use.
The fundamental problem in creating artificial flavor agents is that the artificial flavor to be achieved be as natural as possible. This generally proves to be a difficult task since the mechanism for flavor development in many foods is not completely known. This is noticeable in products having sweet, cocoa butter-like, herbaceous, green, floral and anise (licorice-like) flavoring and aroma characteristics.
Reproduction of sweet, cocoa-butter-like, herbaceous, green, floral and anise flavor and aroma characteristics has been the subject of long and continuing searches by those engaged in the production of foodstuffs and beverages. The severe shortage of food in many parts of the world has given rise to the development of previously unused sources of protein which are unpalatable. Accordingly, the need has arisen for the use of flavoring materials which will make such sources of protein palatable to human sensory organs.
Even more desirable is a product that can serve to substitute for difficult-to-obtain natural perfumery oils and at the same time substitute for natural flavoring ingredients in both foodstuffs as well as tobacco. Cocoa-like, sweet, floral and green aroma and taste characteristics in smoking tobacco both prior to and on smoking in the main stream and in the side stream and particularly desirable for uses in conjunction with smoking tobacco and smoking tobacco articles, like cigarettes, cigars and the like.
Oxygenated compounds having a bicyclopentadiene nucleus are known in the prior art and uses thereof in perfumery are also known. Thus, for example, Kheisets and Virezub at Chem. Abstracts, 61, 8199c (Abstract of Zh.Obshch. Khim. 34 (6) 2081-4) discloses for use in perfumery compounds having the structure: ##STR7##
The Zeinalov, et al at Chem. Abstracts, 68, 49319d, discloses the compound having the structure: ##STR8## wherein R is methyl, n-propyl or n-butyl.
Opdyke in Chem. Abstracts, 92:11070y (Abstract of Food, Cosmet. Toxicol. 1976, 14, Suppl. 889) discloses the compound having the structure: ##STR9## in fragrance raw materials and its toxicological properties.
For use in perfumery, U.S. Pat. No. 3,593,745 issued on Aug. 10, 1971 discloses the compound having the structure: ##STR10##
The compound having the structure: ##STR11## is disclosed in United Kingdom Pat. No. 815,232 issued on June 24, 1959.
Furthermore, the compound having the structure: ##STR12## has been in use in the perfume industry for the past ten years and is known as "Cyclaprop".
German Offenlengungsschrift No. 2,642,519 published on Mar. 23, 1978 and abstracted in Chem. Abstracts, 91:56477g discloses for use in perfumery the compounds having the structures: ##STR13## and generically the compound having the structure: ##STR14## wherein R 7 is alkyl or alkenyl.
U.S. Pat. No. 4,123,394 issued on Oct. 31, 1978 discloses specifically the compound having the structure: ##STR15## and generically the compound having the structure: ##STR16## wherein R 8 is hydrogen, acyl, alkyl or alkenyl.
Arctander, "Perfume and Flavor Chemicals (Aroma Chemicals)", 1969 at monograph 1582 discloses 3a, 4,5,6,7,7a-hexahydro-4,7-methano-5-indano having the structure: ##STR17## and indicates it to be a semi-solid crystalline mass or a viscous pale straw colored or almost colorless liquid having a peculiar earthy, sweet, musky odor of moderate tenacity. Arctander indicates that "a number of adducts and derivatives have been made and a few have become useful in perfume chemicals" and further that this material has notes in common with sandalwood, oakmoss, cedarwood and galbanum and it could be used in conjunction with certain materials. Arctander further states that this compound is stable in soap and offers a low cost material for soap, detergent and other household product fragrances and its musky character blends well with woody and amber-like notes but leaves a floral picture out of the question. Arctander further states that this material is rarely offered under its chemical name but it may enter various specialities and perfume bases as a minor component and during the 1965-1966 period of scarcity and high prices of patchouli oil, the subject alcohol found some uses in the creaction of patchouli oil substitutes. Reference is made by Arctander to U.S. Pat. No. 3,271,259 issued on Sept. 6, 1966.
U.S. Pat. No. 3,271,259 issued on Sept. 6, 1966 entitled "Synthetic Lavandin Oil" discloses the use in perfumery of the compound having the structure: ##STR18## particularly in producting synthetic lavandin oil.

THE INVENTION
It has now been determined that certain substituted tricyclodecane derivatives are capable of imparting a variety of flavors and fragrances to various consumable materials. Briefly, our invention contemplates augmenting or enhancing the flavors and/or fragrances of such consumable materials by adding thereto a small but effective amount of at least one such substituted tricyclodecane derivatives defined according to the generic structure: ##STR65## wherein Y is a moiety having a structure selected from the group consisting of: ##STR66## wherein one of the dashed lines represents a carbon-carbon single bond and the other of the dashed lines represents a carbon-carbon double bond; wherein R 1 and R 2 represent hydrogen or methyl with the proviso that one of R 1 and R 2 is hydrogen and the other of R 1 and R 2 is methyl; wherein R 3 is hydrogen, C 1 -C 3 acyl, C 3 or C 4 alkyl or C 3 or C 4 alkenyl; wherein R 4 , R 5 and R 6 represent hydrogen or methyl with the additional proviso that one of R 4 , R 5 and R 6 is methyl and the other two of R 4 , R 5 and R 6 is hydrogen and flavoring (e.g., for foodstuffs, chewing gum, chewing tobaccos, medicinal products and smoking tobacco) and fragrance compositions (e.g., perfume compositions and compositions for augmenting or enhancing the aroma of perfumed articles, such as solid or liquid anionic, cationic, nonionic, zwitterionic detergents or fabric softeners or cosmetic powders) containing such substituted tricyclodecane derivatives. The invention also contemplates novel processes for producing such compounds.
The substituted tricyclodecane derivatives produced according to the processes of our invention which are used in practicing that part of our invention concerning flavoring and fragrance compositions are actually racemic mixtures rather than individual stereoisomers, such as is the case concerning isomers of patchouli alcohol isomers which are obtained from patchouli oil.
The substituted tricyclodecane derivatives of our invention insofar as their fragrance profiles are concerned have green, floral, woody, patchouli-like, musty/camphoraceous, rosey, woody, anisic, ionone-like, fruity (banana), spicey (cinnamic), bitter sweet, milky, petitgrain-like, lavender, bergamot-like, fatty and minty aromas with spicey, green, basil, raspberry-like, sweatey, pith-like, pumpkin-like and creamy undertones and fruity/berry intense aromas on dry out.
Insofar as their flavor uses are concerned, (e.g., foodstuffs, chewing gums, medicinal products and chewing tobaccos), the substituted tricyclodecane derivatives of our invention have sweet, cocoa butter-like, herbaceous, green, floral, and anise aroma profiles and sweet, cocoa butter-like, herbaceous, green, floral and anise flavor profiles.
Insofar as smoking tobacco flavors are concerned, the substituted tricyclodecane derivatives of our invention have cocoa-like, sweet, floral and green aroma profiles prior to smoking and sweet, floral and aromatic aroma and taste nuances on smoking in both the main stream and the side stream.
The following table sets forth the structure and organoleptic property profiles for specific compounds according to the Examples listed herein and located infra:

The substituted tricyclodecane derivatives produced according to the process of our invention which are used in practicing that part of our invention concerning flavor and fragrance compositions may be mixtures of isomers or they may be substantially pure forms of exo or endo isomers or specific stereoisomers such as the case concerning isomers of patchouli alcohol which are obtained from patchouli oil.
The substituted tricyclodecane derivatives prepared according to our invention can be obtained by reacting either mixtures or specific isomers of dimethyl cyclopentadiene and these isomers have the structures: ##STR77##
The compounds having the structures: ##STR78## may be represented in admixture by the structural representation: ##STR79##
These materials may be prepared by dimerizing one or two or a mixture of all three of the methyl cyclopentadiene isomers having the structures: ##STR80## In addition, other isomers of the dimethylcyclopentadiene structure exist.
The ester derivatives, e.g., the formate, acetate and propionate derivatives of dimethylcyclopentadiene of our invention having the structures: ##STR81## may be prepared by reacting one or more of the isomers of dimethylcyclopentadiene as set forth above with an appropriate alkanoic acid or mixture of alkanoic acids in the presence of a protonic acid or a Lewis acid. Examples of protonic acids useful in this reaction are sulfuric acid, phosphoric acid, para toluene sulfonic acid, methane sulfonic acid and acid clays, and acid ion exchange resins.
Examples of Lewis acids which may be used are borontrifluoride, borontrifluoride etherate, zinc chloride and stannic chloride.
The reaction temperature may vary from about 0° C. up to about 50° C. with a reaction temperature of approximately 10° C. being preferred and the resulting yield is from 25 up to 50% by weight of the theoretical yield based on the amount of methyl cyclopentadiene dimer reactant present.
The concentration of acid, whether it be Lewis acid or protonic acid catalyst in the reaction mass, may vary from 0.01% up to 1 mole percent based on the weight of the reaction mass. The mole ratio of methyl cyclopentadiene dimer:carboxylic acid may vary from about 1:1 up to about 1:3 moles methyl cyclopentadiene dimer:carboxylic acid.
The resulting esters may also be prepared using esterification reagents other than alkyl carboxylic acids, for example, alkanoic acid anhydrides and mixed alkanoic acid anhydrides, such as, acetic anhydride, propionic anhydride and mixed acetic-propionic anhydride. In the alternative, other estification reagents may be used, such as acyl halides, for example, acetyl chloride, acetyl bromide, propionyl chloride and propionyl bromide. When acylating agents, such as alkanoic acid anhydrides and acyl halides are used, the mole ratio of dimethyl bicyclopentadiene dimer:esterifying reagent preferably is about 1:1.
The alcohol derivatives of the substituted tricyclodecane derivatives of our invention having the structures: ##STR82## are prepared by hydrolyzing the esters prepared as indicated above. The hydrolysis takes place in the presence of a strong alkali metal hydroxide, such as 10 up to 50% by weight sodium hydroxide. It is preferred that from 1 up to 2 moles of sodium hydroxide be used per mole of ester derivative. The hydrolysis preferably also takes place from about 40° C. up to reflux, usually about 100°-120° C. as a maximum.
Instead of carrying out the reaction in two steps; first forming the ester and then hydrolyzing the ester to form the alcohol using the dimethyl bicyclopentadiene derivative as a starting reactant, the entire reaction can be done using one reactor without isolation of the ester; and this one reactor reaction preferably is carried out using the formate ester as an intermediate. In summary, the reaction sequence is illustrated by the following two reactions: ##STR83## wherein one of R 1 or R 2 is methyl and the other of R 1 or R 2 is hydrogen and wherein one of R 4 , R 5 and R 6 is methyl and the other two of R 4 , R 5 and R 6 is hydrogen; wherein R 3 ' is C 1 -C 3 acyl and wherein M represents alkali metal, such as sodium, potassium and lithium, wherein one of the dashed lines represents a carbon-carbon single bond and the other of the dashed lines represents a carbon-carbon double bond.
The reaction to form the ether derivative of the methyl cyclopentadiene of our invention according to the reaction: ##STR84## wherein R 3 ' represents C 2 -C 4 alkyl or C 3 -C 4 alkenyl is carried out under conditions similar to those for preparation of the ester with the exception that, in general, the temperature of reaction is somewhat higher. The reaction is carried out between a C 2 -C 4 alkanol or a C 3 or C 4 alkenol and one or more of the dimethyl bicyclopentadiene derivatives as enumerated above. It is preferred to use from about 1 up to 3 moles of alkanol or alkenol per mole of dimethyl dicyclopentadiene dimer. It is preferred that the catalyst be either a Lewis acid, such as boron trifluoride, boron trifluoride etherate, zinc chloride or stannic chloride or a protonic acid, such as sulfuric acid, para toluene sulfonic acid or phosphoric acid. It is further preferred that the reaction temperature be from about 25° C. up to reflux temperature, with reflux temperature being between about 100° and 125° C.
The ketone derivative of the dimethyl dicyclopentadiene dimer of our invention having the structures: ##STR85## are prepared by oxidation of the corresponding alcohols using oxidizing agents, such as copper chromite or Jones reagents. The reaction sequence is illustrated thusly: ##STR86## Also useful is sodium dichromate, Jones reagent or C r O 3 the like. The reaction that takes place is a chemical oxidation wherein equivalent quanitites of oxidizing agent, e.g., sodium dichromate and alcohol are utilized. When copper chromite is used, the reaction is in the nature of a catalytic dehydrogenation. Thus, a catalytic quantity of copper chromite is all that is necessary. The reaction when carried out using catalytic dehydrogenation is preferably carried out at temperature of between 180° and 220° C. at atmospheric pressure. When using the oxidizing reaction and using such oxidizing reagents as sodium dichromate or chromate trioxide, the reaction temperature is preferably in the range of from about 20° C. up to about 80° C. with the use of a solvent being preferred, e.g., toluene or methylene dichloride. Pyrididiumchlorochromate may also be used as an oxidizing agent with the temperature of reaction being in the range of between about 25° C. and about 100° C.
In summary, the reaction of the hydroxy derivative of the dimethyl bicyclopentadiene to the keto derivative of the dimethyl bicyclopentadiene derivative of our invention is illustrated according to the reaction: ##STR87## wherein one of R 1 or R 2 is methyl and the other of R 1 or R 2 is hydrogen; and wherein one of R 4 , R 5 and R 6 is methyl and the other two of R 4 , R 5 and R 6 are hydrogen, wherein one of the dashed lines represents a carbon-carbon single bond and the other of the dashed lines represents a carbon-carbon double bond.
In producing the compounds having the structures: ##STR88## compounds having the structures: ##STR89## or mixtures thereof are preferably reduced using a reducing agent, such as hydrogen under pressure in the presence of a hydrogenation catalyst, such as Raney nickel, and supported palladium or platinum on carbon or calcium carbonate (e.g., a "Lindlar" catalyst of 5% palladium on calcium carbonate). By the same token, ethers and esters may also be hydrogenated whereby the double bond on the dimethyl bicyclopentadiene derivative is reduced to a carbon-carbon single bond according to the reaction: ##STR90## wherein R 3 represents hydrogen, C 3 or C 4 alkenol or C 2 -C 4 alkyl or C 1 -C 3 acyl; one of R 1 or R 2 is methyl and the other of R 1 or R 2 is hydrogen; and one of R 4 , R 5 and R 6 is methyl and the other two of R 4 , R 5 and R 6 represents hydrogen; wherein one of the dashed lines represents a carbon-carbon single bond and the other of the dashed lines represents a carbon-carbon double bond. When R 3 is alkenyl, the hydrogenation reaction will produce a mixture of alkyl and alkenyl ethers, the proportion of alkyl ether in the mixture being a function of the extent (time, pressure and temperature) of hydrogenation carried out. A long period of time of hydrogenation coupled with high pressure and high temperature will yield total elimination of the carbon-carbon double bonds in the molecule thereby yielding alkyl ethers of dimethyl bicyclopentane derivatives, either in pure form or in admixture themselves depending upon the nature of the dimethyl bicyclopentadiene starting reactant used. The range of reaction temperature may vary from about 10° C. up to about 50° C. with a preferred reaction pressure of from about 25 psig up to 300 psig. It is preferred that the hydrogenation reaction be carried out in the presence of an inert solvent, such as isopropyl alcohol, ethyl alcohol, methyl alcohol or n-butanol. When such a solvent is used, it is preferred that the ratio of the dimethyl bicyclopentadiene derivative:solvent (weight:weight) be between about 1:1 and 3:1 with a preferred ratio being 2.5:1.
In producing carboalkoxy esters (e.g., "carbonates" of the dimethyl bicyclopentadiene derivatives of our invention having the structures: ##STR91## the starting materials are the hydroxyl derivatives of the dimethyl bicyclopentadiene derivatives of our invention having the structures: ##STR92## These compounds may either first be reacted with such materials as methyl chloroformate to form the methyl carbonate derivatives having the structures: ##STR93## in a 1:1 mole ratio of reactants using ambient temperature and pressure or the reaction (in order to effect a higher yield . . . quantitative yields) may be carried out by first reacting the hydroxyl derivatives of the dimethyl bicyclopentadiene derivatives of our invention having the structures: ##STR94## with an alkali metal hydride, such as lithium hydride thereby forming the alkali metal salts of the dimethyl bicyclopentadiene derivatives of our invention having the structures: ##STR95## wherein M is sodium, potassium or lithium. These organometallic derivatives may in admixture or individually be reacted with dialkyl carbonate such as dimethyl carbonate thereby producing the desired carbonate derivatives of the dimethyl bicyclopentadienes of our invention according to the reaction: ##STR96##
The temperature range most preferred for the foregoing reaction when reacting the alkali metal hydride with the alcohol derivative of the dimethyl bicyclopentadiene is from about 40° C. up to about 70° C. and it is most preferred to carry out the reaction in an inert cosolvent, such as toluene or xylene. After the reaction is completed, the second reaction with the dialkyl carbonate and the organometallic derivative should take place at reflux temperature in the same cosolvent as used in the first reaction with the alkali metal hydride. Thus, for example, if the cosolvent is toluene, the reaction should take place at about reflux or between the temperatures of about 90° C. and about 115° C. The period of time necessary for the reaction to go to completion is between about 2 and about 5 hours. The reaction pressure is preferably atmospheric but super atmospheric pressures may be utilized without any resultant decrease in the yield of desired reaction product.
At the end of each of the foregoing reactions, the reaction product may, if desired, be separated from the resultant reaction mass as by fractional distillation or preparative GLC (vapor phase chromatography). However, if the desired reaction product as above is to be utilized as a reaction intermediate, the necessity of careful rectification of the reaction product in order to achieve odor acceptable substances or flavor acceptable substances is not necessary since the resultant reaction product will be further reacted.
It will be appreciated from the present disclosure that the substituted tricyclodecane derivative according to the present invention can be used to alter, vary, fortify, modify, enhance or otherwise improve the flavor of a wide variety of materials which are ingested, consumed or otherwise organoleptically sensed.
The terms "alter" and "modify" in their various forms will be understood herein to mean the supplying or imparting of a flavor character or note to an otherwise bland, relatively tasteless substance, or augmenting an existing flavor characteristic where the natural flavor is deficient in some regard or supplementing the existing flavor impression to modify the organoleptic character.
The term "enhance" is intended herein to mean the intensification (by use of the substituted tricyclodecane derivative of our invention) of a flavor or aroma note or nuance in a tobacco flavor or foodstuff or perfume composition or a perfumed article without changing the quality of said note or nuance.
A "flavoring composition" is taken to mean one which contributes a part of the overall flavor impression by supplementing or fortifying a natural or artificial flavor in a material or one which supplies substantially all the flavor and/or aroma character to a consumable article.
The term "foodstuff" as used herein includes both solid and liquid ingestible materials for man or animals, which materials usually do, but need not, have nutritional value. Thus, foodstuffs includes meats, gravies, soups, convenience foods, malt, alcoholic, and other beverages, milk and dairy products, seafoods including fish, crustaceans, mollusks, and the like, candies, vegetables, cereals, soft drinks, snacks, dog and cat food, other veterinary products, and the like.
The substituted tricyclodecane derivatives of our invention are also a useful tobacco flavorant and flavor enhancer.
The term "tobacco" will be understood herein to mean natural products such as, for example, burley, Turkish tobacco, Maryland tobacco, flue-cured tobacco and the like including tobacco-like or tobacco-based products such as reconstituted or homogenized leaf and the like, as well as tobacco substitutes intended to replace natural tobacco, such as lettuce and cabbage leaves and the like. The tobaccos and tobacco products in which the substituted tricyclodecane derivatives of our invention are useful include those designed or used for smoking such as in cigarette, cigar and pipe tobacco, as well as products such as snuff, chewing tobacco, and the like.
When the substituted tricyclodecane derivatives of this invention are used in a flavoring composition, they can be combined with conventional flavoring materials or adjuvants. Such co-ingredients or flavoring adjuvants are well known in the art for such use and have been extensively described in the literature. Requirements of such adjuvant materials are: (1) that they be non-reactive with the substituted tricyclodecane derivatives of our invention; (2) that they be organoleptically compatible with the substituted tricyclodecane derivatives of our invention whereby the flavor of the ultimate consumable material to which the substituted tricyclodecane derivatives are added is not detrimentally affected by the use of the adjuvant and (3) that they be ingestibly acceptable, and thus non-toxic or not otherwise non-deleterious. Apart from these requirements, conventional materials can be used and broadly include other flavor materials, vehicles, stabilizers, thickeners, surface active agents, conditioners, and flavor intensifiers.
Such conventional flavoring materials include saturated fatty acids, unsaturated fatty acids and amino acids; alcohols, including primary and secondary alcohols, esters; carbonyl compounds including ketones and aldehydes; lactones; other cyclic organic materials including benzene derivatives, alicyclic compounds, heterocyclics such as furans, pyridines, pyrazines and the like; sulfur-containing materials including thiols, sulfides, disulfides and the like; proteins; lipids, carbohydrates; so-called flavor potentiators such as monosodium glutamate, guanylates, and inosinates; natural flavoring materials such as cocoa, vanilla and caramel; essential oils and extracts such as anise oil; clove oil; and the like; and artificial flavoring materials such as vanillin; and the like.
Specific preferred flavor adjuvants are as follows:
Ethyl-2-methyl butyrate;
Vanillin;
Butyl valerate;
2,3-Diethyl pyrazine;
Methyl cyclopentenolone;
Benzaldehyde;
Valerian Oil Indian; and
Propylene glycol
When used in perfumery, in order to alter, modify or enhance the aroma of perfume compositions, or perfumed articles the substituted tricyclodecane derivatives of our invention can be used to contribute patchouli-like, peppery, woody, fruity and camphoraceous aromas. As an olfactory agent, the substituted tricyclodecane derivatives of this invention can be formulated into or used as a component of a "perfume composition".
The term perfume composition is used herein to mean a mixture of organic compounds, including, for example, alcohols, aldehydes, ketones, nitriles, esters, 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 of 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) topnotes 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 effect of each ingredient. Thus, the substituted tricyclodecane derivatives of this invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by high-lighting or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of the substituted tricyclodecane derivatives of this 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 1 percent of the substituted tricyclodecane derivatives of this invention, or even less, can be used to impart a patchouli scent with peppery, woody, fruity and camphoraceous notes to soaps, cosmetics, 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, the effect desired on the finished product and particular fragrance sought.
The substituted tricyclodecane derivatives of this 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 percent of one or more of the substituted tricyclodecane derivatives will suffice to impart a patchouli aroma with peppery, woody, fruity and camphoraceous notes. Generally, no more than 0.5 percent is required.
In addition, the perfume composition can contain a vehicle or carrier for the substituted tricyclodecane derivatives 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 or components for encapsulating the composition.
The following examples are given to illustrate embodiments of the invention as it is presently preferred to practice it. It will be understood that these examples are illustrative, and the invention is not to be considered as restricted thereto except as indicated in the appended claims.
