Referring to FIGS. 17 and 18 there is provided a process for forming scented polymer elements (wherein the polymer may be a thermoplastic polymer such as low density polyethylene or polypropylene or copolymers of ethylene and vinly acetate or mixtures of polymers and copolymers such as copolymers of ethylene and vinyl acetate and polyethylene) such as pellets useful in the formation of plastic particles useful in fabricating certain articles which may be perfumed. This process comprises heating the polymer or mixture of polymers to the melting point of said polymer or mixture of polymers, e.g., 250.degree. C. in the case of low density polyethylene. The lower most portion of the container is maintained at a slightly lower temperature and the material in the container is taken off at such location for delivery through the conduit. Thus, referring to FIGS. 17 and 18, in particular, the apparatus used in producing such elements comprises a device for forming the polymer containing perfume, e.g., polyethylene or polyethylene-polyvinyl acetate or mixtures of the same of polypropylene, which comprises a vat or container 212 into which the polymer taken alone or in admixture with other copolymers and the perfuming substance which is at least one of the adamantane derivatives of our invention or mixtures of adamantane derivatives and other compatible perfumes is placed. The container is closed by means of an air-tight lid 228 and clamped to the container by bolts 265. A stirrer 273 traverses the lid or cover 228 in an air-tight manner and is rotatable in a suitable manner. A surrounding cylinder 212A having heating coils which are supplied with electric current through cable 214 from a rheostate or control 216 is operated to maintain the temperature inside the container 212 such that the polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ polymers at such a temperature that the viscosity will be in the range of 90-100 sayboldt seconds. The heater 218 is operated to maintain the upper portion of the container 212 within a temperature range of, for example, 220.degree.-270.degree. C. in the case of low density polyethylene. The bottom portion of the container 212 is heated by means of heating coils 212A regulated through the control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container 212 within a temperature range of 220.degree.-270.degree. C.
Thus, the polymer or mixture of polymers added to the container 212 is heated from 10-12 hours, whereafter the perfume composition or perfume material which contains one or more of the adamantane derivatives of our invention is quickly added to the melt. Generally, about 10-45 percent by weight of the resulting mixture of the perfumery substance is added to the polymer.
After the perfume material is added to the container 212, the mixture is stirred for a minutes, for example, 5-15 minutes and maintained within the temperature ranges indicated previously by the heating coil 212A. The controls 216 and 220 are connected through cables 224 and 226 to a suitable supply of electric current for supplying the power for heating purposes.
Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 232 having a multiplicty of orifices 234 adjacent to the lower side thereof. The outer end of the conduit 232 is closed so that the liquid polymer in intimate admixture with one or more of the adamantane derivatives of our invention or mixture of adamantane derivatives and one or more other substances, will continuously drop through the orifices 234 downwardly from the conduit 232. During this time, the temperature of the polymer intimately admixed with the perfumery substance in the container 212 is accurately controlled so that a temperature in the range of from about 240.degree.-250.degree. C., for example, (in the case of low density polyethylene) will exist in the conduit 232. The regulation of the temperature through the controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dripping or dropping of molten polymer intimately admixed with the perfume substance which is all of or which contains one or more of the adamantane derivatives of our invention, through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.
When the droplets 236 fall onto the conveyor 238 they form pellets 244 which harden almost instananeously and fall off the end of the conveyor 238 into a container 250 which is advantageously filled with water or some other suitable cooling liquid to insure the rapid cooling of each of the pellets 244. The pellets 244 are then collected from the container 250 and utilized for the formation of other functional products, e.g., garbage bags and the like.
THE INVENTION
The present invention provides adamantane derivatives defined according to the structure: ##STR45## wherein R.sub.1 is hydrogen or acetyl; R.sub.2 is hydrogen or methyl; and R.sub.3 is hydrogen or methylene; and the dashed line represents a carbon-hydrogen single bond or a carbon-methylene double bond with the provisos that when R.sub.2 is methyl then R.sub.1 and R.sub.3 are both hydrogen; and when R.sub.2 is hydrogen, R.sub.3 is methylene and the dashed line represents a carbon-methylene double bond.
The adamantane derivatives of our invention produced according to prior art processes are known in the prior art per se and have now been found to be capable of augmenting or enhancing woody, earthy, camphoraceous, phenolic, piney, balsamic and patchouli-like aromas with camphoraceous, armoise, animalic, woody and minty topnotes thus fulfilling a need in the field of perfumery.
The processes for producing the adamantane derivatives of our invention are also known in the prior art and involve the following reactions which are also exemplified in Examples I-VI, infra: ##STR46##
The following table represents the compounds the perfumery uses of which are the subject of our invention and their respective organoleptic properties:
TABLE I______________________________________Structure of Compound Perfumery Properties______________________________________The compound having An earthy, camphoraceous andthe structure: phenolic aroma. ##STR47##produced according toExample III. ##STR48## A piney, camphoraceous, balsamic and woody aroma with camphoraceous armoise and animalic topnotes.produced according toExample V. ##STR49## A camphoraceous, woody, patchouli aroma with camphoraceous, woody, minty and animalic topnotes.produced according toExample VI.______________________________________
One of the adamantane derivatives prepared in accordance with the processes of the prior art and one or more auxilliary perfume ingredients including, for example, alcohols other than the hydroxy adamantane derivatives or our invention, aldehydes, ketones, terpenic hydrocarbons, nitriles, esters, other than the adamantane esters of our invention, lactones, natural essential oils and synthetic essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly, and preferably, in piney fragrances and patchouli fragrances. Such perfume compositions usually contain (a) the main note or the "bouquet" or foundation stone of the composition; (b) modifiers which round out an accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all states of evaporation and substances which retard evaporation; and (d) topnotes which are usually low-boiling fresh-smelling materials.
In perfume compositions, it is the individual components which contribute to their particular olfactory characteristics, however, the overall sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, one of the adamantane derivatives prepared in accordance with the processes or our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of one of the adamantane derivatives prepared in accordance with the processes of our invention which will be effective in perfume compositions as well as in perfumed articles (e.g., anionic, nonionic, cationic, or zwitterionic detergents, soaps and fabric softener compositions and articles) and colognes depends upon 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 0.01% of one of the adamantane derivatives prepared in accordance with the processes of our invention and less 50% of one of the adamantane derivatives prepared in accordance with the processes of our invention or even less (e.g., 0.005%) can be used to impart a woody, earthy, camphoraceous, phenolic, piney, balmsamic and patchouli aroma with camphoraceous, armoise, animalic, woody and minty topnotes to soaps, cosmetics, anionic, cationic, nonionic, or zwitterionic detergents, fabric softener compositions, fabric softener articles, perfumed polymers or other articles. The amount employed can range up to 70% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.
One or more of the adamantane derivatives prepared in accordance with the prior art are useful (taken alone or together with other ingredients in perfume compositions) as (an) olfactory component(s) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations, such as creams, deodorants, hand lotions and sun screens; powders, such as talcs, dusting powders, face powders, perfumed polymers and the like. When used as (an) olfactory component(s) as little as 0.2% of one or both of the adamantane derivatives of our invention, prepared in accordance with the prior art of our invention, will suffice to impart an intense and substantive woody, earthy, camphoraceous, phenolic, piney, balsamic and patchouli aroma with camphoraceous, armoise, animalic, woody and minty topnotes to patchouli formulations and to vetiver formulations and to pine formulations. Generally, no more than 6% of one or both of the adamantane derivatives of our invention produced in accordance with the processes of our invention based on the ultimate end product are required in the perfumed article composition. Accordingly, the range of one or more of the adamantane derivatives of our invention in a perfumed article may vary from one 0.2% up to about 6% by weight of the ultimate perfumed article.
In addition, the perfumed compositions or fragrance compositions of our invention can contain a vehicle or carrier for one or both of the adamantane derivatives prepared in accordance with the processes of our invention. The vehicle can be a liquid, such as a non-toxic alcohol, e.g., ethyl alcohol, a glycol, e.g., propylene glycol or the like. The carrier can also be an absorbent solid, such as a gum (i.g., gum arabic, xanthan or guar gum) or components for encapsulating the composition (such as gelatin as by coacervation or such as a urea-formaldehyde pre-polymer when forming a urea-formaldehyde polymer wall around a liquid perfume center.
It will thus be apparent that one of the adamantane derivatives of our invention can be utilized either to alter, modify or enhance sensory properties, particularly organoleptic properties such as fragrances of a wide variety of consumable materials.
The following examples illustrate methods (primarily disclosed in the prior art) used to manufacture the adamantane derivatives useful in our invention.
Examples following Example VI (Example VII et seq) illustrate the organoleptic utilities of the adamantane derivatives of our invention.
