Description

BACKGROUND OF THE INVENTION

Our invention relates to the novel reaction products which are schiff base reaction products of alkyl anthranilates having the structure: ##STR5## wherein R" represents methyl or ethyl and ketones or aldehydes having the structure: ##STR6## wherein R' is hydrogen or methyl and R is one of the moieties: ##STR7## and the organoleptic uses thereof in augmenting or enhancing the aroma or taste of perfume compositions, colognes, perfumed articles, foodstuffs, chewing gums, toothpastes, medicinal products and chewing tobaccos; and in enhancing or augmenting the effect of deodorancy; as a maskant for malodors emanating from the axilliary regions of mammalian species or as a maskant for malodors in detergent compositions or fabric softeners; and as a maskant for malodors for use in conjunction with other perfumery materials.

Inexpensive chemical compositions of matter which can provide concord grape, floral, orange blossom and neroli aroma and taste nuances for use in grape, neroli, mandarine and tangerine flavored foodstuffs are highly desirable in the food flavoring art as well as in the flavoring art for flavoring toothpastes, medicinal products, chewing gums and chewing tobaccos.

Furthermore, inexpensive chemical compositions of matter which can provide grape, animalic and rose aromas with hay-like, coumarinic, tonka absolute, honey and fatty topnotes and which are highly substantive and long-lasting are highly desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute desired nuances to perfumery compositions as well as perfumed articles including solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions and fabric softener articles are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

Still more desirable are materials which can both provide useful fragrance effects including a high degree of substantivity and a long-lasting fragrance; and also provide a deodorancy effect wherey malodors can be masked by means of the use of the compound in, for example, compositions for application to the axillary regions of mammalian species including human beings.

Reaction products of carbonyl-containing compounds and amine-containing compounds are well known in the art of flavoring and in the art of perfumery. Thus, U.S. Letters Pat. No. 4,618,501 issued on Oct. 21, 1986 discloses the flavoring of foodstuffs with alpha, beta-keto-amines and states that an alpha,beta-keto-amine having a nutty corn, cereal aroma may be used for flavoring compositions for foods having the structure: ##STR8## wherein R.sub.1, R.sub.2 and R.sub.3 are selected from the group consisting of a saturated or unsaturated alkyl straight or branched chain hydrocarbons having from 1-3 carbon atoms.

U.S. Letters Pat. No. 3,625,710 issued on Dec. 7, 1971 discloses the use of aldimines as chocolate-like flavors which aldimines are resulting from the reaction product of amines and aldehydes, for example, N-isobutylidenefurfurylamine, N-isopentylidenefurfurylamine, N-isopentylideneisopentylamine.

Schiff bases are also well known in the art of perfumery. Thus, for example, Chemical Abstracts Volume 103, 1985, No. 123134z (Abstract of Japan Kokai No. 60/78951 discloses the use in perfumery of compounds having the structure: ##STR9##

Arctander "Perfume and Flavor Chemicals (Aroma Chemicals)", Volume II, published by the Author in 1969 discloses the organoleptic properties of the schiff base of methyl anthranilate and vanillin having the structure: ##STR10## thusly:

"3070: VANILLIN-METHYLANTHRANILATE ##STR11## Viscous, dark-yellowish liquid, occasionally with an orange-reddish tint, or an olive-green color.

Insoluble in water, soluble in alcohol and oils.

Intensely sweet, balsamic-floral odor of very good tenacity. The odor varies considerably from one sample (supplier) to another, a fact which is often observed in "Schiff's bases". Generally, a mild surplus of the aldehyde component is preferable, except in cases of very pungent aldehydes such as Cuminaldehyde, Cinnamic aldehyde, Methylcinnamic aldehyde, etc.

The title material has very little use in perfumes, and is simply missing from most perfume laboratories. It may be considered as a curiosity, more than a practical perfume material, but it is briefly mentioned in this work because it may often "occur" in a perfume, since the use of Vannillin and Methylanthranilate in the same composition is not a very rare or unusual case. The addition of Vanillin directly into Methylanthranilate may often cause a strong coloring, brown or orange, of the mixture, and it is recommended not to add these materials in sequence, one next to the other.

Among scores of suggested "Schiff's bases", only very few have become standard perfume items, and the title material is not one of them. But it is classified as "interesting", by some perfumers.

Prod.: by condensation of Vanillin with Methylanthranilate in molecular proportions, preferably in a suitable diluent to prevent violent darkening, and to render the final product more pourable, handy for use.

33-1029; 90-799;". Arctander also discloses the organoleptic properties of Vanillin-ethyl carbonate-phenetidine, thusly:

"3069: VANILLIN-ETHYLCARBONATE-para-PHENETIDINE

Vanillin-para-phenetidine ethylcarboxylate. "Eupyrin". ##STR12## Yellowish needle-like crystals. M.P. 88.degree. C.

Very slightly soluble in water, moderately soluble in alcohol, soluble in hot alcohol and oils.

The title material is briefly mentioned because it behaves in a rather peculiar manner. Although it has an unquestionable odor of Vanillin-type, rather soft, but quite pleasant and not exactly weak, its aqueous solution or the dry material itself has hardly any taste at all.

This peculiarity has not been explained in literature, but it could well be that the material (molecule), part of which is an aromatic aminoether, has mildly anaesthetic effect upon the human mucous membranes. Many members of this chemical series have anaesthetic effect.

The material was developed many decades ago for pharmaceutical purposes, but was also introduced to the perfume and flavor industry at that time. It has no longer importance to perfumes or flavors, but it is still used in pharmacy.

96-137; 100-411;".

The schiff base reaction products of our invention have unexpected, unobvious and advantageous organoleptic properties including deodorancy properties as opposed to the compounds of the prior art.

The book "Flavor & Fragrance Materials-1987" published by Allured Publishing Corporation, P.O. Box 318, Wheaton, Ill. 60189-0318 discloses on page 154 the commercial availability of the following schiff bases:

Methyl anthranilate and amyl cinnamic aldehyde; Methyl anthranilate and hydroxy citronellal; Methyl anthranilate and lilial; Methyl anthranilate and anisic aldehyde; Methyl anthranilate and decanal; Methyl anthranilate and lyral; Methyl anthranilate and iso-nonylaldehyde; Methyl anthranilate and phenylacetaldehyde; Schiff bases are also known to be useful as intermediates in producing other fragrance materials. Thus, U.S. Letters Pat. 3,898,283 issued on Aug. 5, 1975 discloses novel schiff base intermediates used in producing 4 or 5 phenylpentenals having the structure: ##STR13## wherein X is a moiety selected from the group consisting of: ##STR14## and wherein R.sub.a is hydrogen or methyl.

Nothing in the prior art however discloses the novel reaction products or reaction product mixtures of our invention having unobvious, unexpected and advantageous organoleptic properties.

Indeed, nothing in the prior art is indicative of the novel schiff base reaction products of our invention having deodorizing properties that is, having a deodorant value of 0.50 up to 3.5 as measured by the deodorant value test described in U.S. Letters Pat. No. 4,304,679 incorporated by reference herein or having a Lipoxidase-inhibiting capacity of at least 50% and a Malodour reduction value of from 0.25 up to 3 as measured by the Malodour reduction value test disclosed in U.S. Letters Pat. No. 4,663,068 incorporated by reference herein.

C. at 8.degree. C. per minute).

The peaks indicated by reference numerals 301, 302 and 303 are the peaks for the components of the schiff base reaction product including the compound having the structure: ##STR31##

Referring to FIG. 10, FIG. 10 is a schematic cut-away elevation diagram of the extrusion and pelletizing apparatus useful in carrying out a process for incorporation of one or more of the schiff base reaction products of our invention including compounds included in the generic structure: ##STR32## wherein R' is hydrogen or methyl; R" is methyl or ethyl; and R is one of the moieties: ##STR33## into polymers during the operation of said apparatus. Motor 15 drives the extruder screws located at 23A in barrel 16, the extruder being operated at temperatures in the range of about 150.degree. C. up to about 250.degree. C. At the beginning of the barrel, resin at source 12 together with additives, e.g., opacifiers, processing aids, colors, pearlescent agents and densifiers at location 13 is added via addition funnel 14 into the extruder. Simultaneously (when the operation reaches "steady state"), one or more of the schiff base reaction products of our invention is added to the extruder at one, two or more of barrel segments 3-8 of the extruder (which may be a twin screw or single screw extruder) at locations 18a, 18b, 18c and 18d by means of gear pump 23 from source 17. From source 19 into barrel segments 5-10, the gaseous or liquid blowing agents, e.g., nitrogen, carbon dioxide and the like are added simultaneously with the addition of one or more of the schiff base reaction products of our invention. The feed rate range of the resin is about 80-300 pounds per hour. The feed rate range of one or more of the schiff base reaction products of our invention taken alone or further together with other perfumant(s) is between 1 and 45% of the feed rate range of the resin. The blowing agent rate range is such that the pressure of the gas or the pressure over the liquid being fed into the extruder is between about 50 and 200 psig. If desired, the extruded ribbon or cylinder may be passed through water bath 20 and pelletizer 21 into collection apparatus 21a.

Referring to FIGS. 8 and 9, there is provided a process for forming scented polymer pellets (wherein the polymer may be a thermoplastic polymer such as low density polyethylene or polypropylene or copolymers of ethylene and vinyl 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. 8 and 9, 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 same or polypropylene which comprises a vat or container 212 into which the polymer taken alone or in admixture with other polymers or copolymers and the perfuming substance which is at least one of the schiff base reaction products of our invention including compounds defined according to the generic structure: ##STR34## (wherein R, R' and R" are defined, supra) and, if desired, 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 rheostat 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 at least one of the schiff base reaction products of our invention containing a compound defined according to the generic structure: ##STR35## (wherein R, R' and R" are defined, supra) 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 containing at least one of the schiff base reaction products of our invention is added to the container 212, the mixture is stirred for a few 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 multiplicity 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 at least one of the schiff base reaction products of our invention containing a compound defined according to the generic structure: ##STR36## (wherein R, R' and R" are defined, supra) or mixture of perfume substances and at least one of the schiff base reaction products of our invention 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 of molten polymer intimately admixed with the perfume substance which at least contains at least one of the schiff base reaction products of our invention containing a compound defined generically according to the structure: ##STR37## (wherein R, R' and R" are defined, supra), 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 instantaneously 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

Our invention provides schiff base reaction products of alkyl anthranilates defined according to the structure: ##STR38## (wherein R" represents methyl or ethyl) with a ketone or aldehyde defined according to the structure: ##STR39## wherein R' represents hydrogen or methyl and R is one of the moieties: ##STR40## including compounds defined according to the generic structure: ##STR41## wherein R, R' and R" are defined, supra. These schiff base reaction products are produced according to the generic reaction: ##STR42## but this reaction is not intended to limit our invention to production of compounds having the structure: ##STR43## Thus, compounds other than compounds having the structure: ##STR44## are also formed. Hence, by the term "schiff base reaction product" is intended to mean not only compounds having the structure: ##STR45## but other compounds formed along with these compounds as a result of the reaction of alkyl anthranilates having the structure: ##STR46## with ketones or aldehydes having the structure: ##STR47##

More specifically, the schiff base reaction products of our invention including compounds defined according to the generic structure: ##STR48## wherein R, R' and R" are defined, supra, produced according to the process of our invention are capable of augmenting or enhancing or modifying the aroma and taste characteristics of consumable materials including perfume compositions, colognes, perfumed articles (including soaps, anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, optical brightener compositions and drier-added fabric softener articles) perfumed polymers, foodstuffs, chewing gums, toothpastes, medicinal products and chewing tobaccos by imparting thereto:

(i) in the case of perfume compositions and perfumed articles, grape, animalic and rose aromas with hay-like, coumarinic, tonka-absolute, honey and fatty topnotes; and (ii) in the case of foodstuffs, chewing gums, toothpastes chewing tobaccos and medicinal products, concord grape, floral, orange blossom and neroli aromas and taste nuances at 0.1 ppm.

Thus, needs in the fields of perfumery, detergents and cosmetic manufacture and foodstuff, chewing gum, toothpaste, medicinal product and chewing tobacco manufacture are fulfilled.

The schiff base reaction products of our invention, including compounds defined according to the generic structure: ##STR49## wherein R, R' and R" are defined, supra, are also capable of deodorizing detergent powders suitable for use in the washing of fabrics; as well as detergent powders suitable for use as hand soaps. Such detergent powders include bleaching compositions, for example, bleaching compositions comprising a peroxy bleach compound. The schiff base reaction products of our invention including the compounds having the structure: ##STR50## wherein R, R' and R" are defined, supra have deodorancy values as measured by having a Lipoxidase-inhibiting capacity of at least 50% and a Raoult Variance ratio of at least 1.1 and a malodour reduction value of between about 0.25 up to about 3.0 as measured by the malodour reduction value test disclosed in detail in U.S. Pat. No. 4,663,068 the specification for which is incorporated by reference herein; and in addition, a deodorant value of from 0.50 up to 3.5 as measured by the deodorant value test as disclosed in U.S. Pat. No. 4,304,679 the specification for which is incorporated by reference herein.

The reactions to form the schiff base reaction products of our invention including the compounds having the generic structure: ##STR51## wherein R, R' and R" are defined, supra, between the ketones defined according to the structure: ##STR52## and the alkyl anthranilates having the structure. ##STR53## according to the reaction: ##STR54## have the following parameters: (i) the temperature of the reaction is in the range of from about 90.degree. C. up to about 150.degree. C.;

(ii) the pressure over the reaction mass may vary from about 3 mm/Hg. (vacuum) up to about 1 atmosphere with a preferable pressure of between about 5 and about 100 mm/Hg. pressure; (iii) the time of reaction may vary from about 3 up to about 15 hours with a preferred time of reaction of between about 6 and about 12 hours; (iv) the mole ratio of ketone defined according to the structure: ##STR55## to alkyl anthranilate having the structure: ##STR56## may vary from about 1:1 up to about 1.25:1 of total compound having the structure: ##STR57## alkyl anthranilate having the structure: ##STR58## with a preferred mole ratio of between about 1:1 and about 1.1:1 of compound having the structure: ##STR59## alkyl anthranilate having the structure: ##STR60##

At the end of the reaction, the reaction mass may be separated and the reaction product purified as by fractional distillation of one of the schiff base compounds (for example) defined according to the structure: ##STR61## wherein R, R' and R" are defined, supra.

From a practical standpoint when a reaction mixture is created which gives rise to preferred perfumery properties, subsequent fractional distillation to the point of yielding an odor acceptable product is what is desired.

The schiff base reaction products including compounds defined according to the generic structure: ##STR62## wherein R, R' and R" are defined, supra, prepared in accordance with the process of our invention and one or more auxiliary perfume ingredients including, for example, alcohols, aldehydes, ketones, terpinic hydrocarbons, nitriles, esters other than the 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 the floral and lavender fragrance areas. 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) 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 over-all sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, the schiff base reaction products of our invention containing compounds defined according to the generic structure: ##STR63## wherein R, R' and R" are defined, supra, prepared in accordance with the process of 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 schiff base reaction product containing at least one compound defined according to the structure: ##STR64## wherein R, R' and R" are defined, supra, prepared in accordance with the process of our invention which will be effective in perfume compositions as well as in perfumed articles (e.g., anionic, nonionic, cationic and zwitterionic solid or liquid detergents, soaps, fabric softener compositions, drier-added fabric softener articles, optical brightener compositions, perfumed polymers and textile sizing agents) and colognes 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 0.01% of the schiff base reaction product of our invention containing at least one compound defined according to the structure: ##STR65## wherein R, R' and R" are defined, supra, prepared in accordance with the process of our invention and less than 50% of said schiff base reaction product or even less (e.g., 0.005%) can be used to impart grape, animalic and rose aromas with hay-like, coumarinic, tonka absolute, honey and fatty topnotes to solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, optical brightener compositions, textile sizing compositions, perfumed polymers or other products. The amount employed can range up to 100% 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.

The schiff base reaction products of our invention including compounds defined according to the generic structure: ##STR66## wherein R, R' and R" are defined, supra, prepared in accordance with the process of our invention is 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, and perfumed polymers and articles of manufacture produced from said perfumed polymers.

When used as (an) olfactory component(s) as little as 0.2% of the schiff base reaction product of our invention including compounds defined according to the generic structure: ##STR67## prepared in accordance with the process of our invention will suffice to impart an intense and substantive grape, animalic and rose aroma with hay-like, coumarinic, tonka absolute, honey and fatty topnotes to floral, rose and fresh air formulations. Generally, no more than 6% of the schiff base reaction product(s) of our invention including compounds defined according to the structure: ##STR68## based on the ultimate end product is required in the perfumed article composition. Accordingly, the range of schiff base reaction product including compounds defined according to the structure: ##STR69## in the perfumed article is from about 0.2% by weight of the schiff base reaction product up to about 6% by weight of the schiff base base reaction product based on the weight of the perfumed article.

In addition, the perfume composition or fragrance composition of our invention can contain a vehicle or carrier for the schiff base reaction product including compounds defined according to the generic structure: ##STR70## prepared in accordance with the process of our invention. The vehicle can be a liquid, such as a non-toxic alcohol, e.g., ethyl alcohol, a non-toxic glycol, e.g., propylene glycol or the like. The carrier can also be an absorbent solid, such as a gum (e.g., gum arabic, guar gum or xanthan gum) or components for encapsulating the composition (such as gelatin) as by coacervation; or such as urea-formaldehyde polymers forming a capsule shell around a liquid perfume center).

Our invention also relates to the utilization of controlled release technology for the controlled release of perfumes into gaseous environments from polymers such as mixtures of epsilon polycaprolactone polymers and polyethylene which polyepsilon caprolactone polymers are defined according to at least one of the structures: ##STR71## wherein "n" is from about 50 up to about 1,200 with the proviso that the average "n" in the system varies from about 150 up to about 700 according to the mathematical statement:

[700.ltoreq.n.ltoreq.150] with the term "n" being the average number of repeating monomeric units for the epsilon polycaprolactone polymer. The perfumed material's release rate from such polymer mixture is close to "zero order". As a general rule, the release rate in a polymeric matrix is proportional to t.sup.-1/2 until about 60% of the functional fluid is released from the polymeric matrix. The release rate thereafter is related exponentially to time as a general rule according to the equation: ##EQU1## wherein k.sub.1 and k.sub.2 are constants. According to Kydonieus, "Controlled Release Technologies: Methods, Theory, and Applications" (cited, supra, the amount of perfume composition released is proportional to time as long as the concentration of perfume material present, e.g, the schiff base reaction product of our invention including compounds defined according to the generic structure: ##STR72## is higher than the solubility of the agent in the matrix. Thus, such dispersed systems are similar to the dissolved systems except that instead of a decreased release rate after 60% of the perfume material has been emitted, the relationship holds almost over the complete release curve. Kydonieus further states, that if one assumes that the release of functional fluid by diffusion is negligible in monolithic erodible systems, the speed of erosion will control the release rate and release by erosion by a surface-area-dependent phenomenon, the release constant (zero order) as long as the surface area does not change during the erosion period. This is the case with the polymers containing one or more schiff base reaction products of our invention including compounds defined according to the generic structure:

The polyepsilon caprolactone homopolymers which are ultimately taken in admixture with such materials as polyethylene useful in the practice of our invention may also be stabilized using stabilizers as defined in United States Letters Patent No. 4,360,682 issued on Nov. 23, 1982, the specification for which is incorporated herein by reference. The stabilizing materials which stabilize the polyepsilon caprolactone useful in conjunction with our invention against discoloration are dihydroxybenzenes such as hydroquinone or compounds having the formula: ##STR73## in which R.sub.1 is alkyl of from 1 to 8 carbon atoms, and R.sub.2 is hydrogen or alkyl of 1 to 8 carbon atoms. It is preferable to have such stabilizer in the polyepsilon caprolactone homopolymer in an amount of from about 100 to 500 ppm. Such stabilizers do not interfere with the functional fluids dissolved and/or adsorbed into the polymeric matrix.

The method of incorporating the schiff base reaction product(s) of our invention or perfume compositions containing same into the polymers may be according to the technique of United States Letters Patent 3,505,432 issued on Apr. 7, 1970 (the specification for which is incorporated by reference herein) or United States Letters Patent No. 4,247,498 issued on Jan. 27, 1981, the disclosure of which is incorporated by reference herein.

Thus, for example, a first amount of liquid polyethylene-polyepsilon caprolactone polymer mixture (50:50) is mixed with the schiff base reaction product(s) of our invention. Drops are formed from the mixture and the drops are solidified. The solidified drops are then melted, if desired, with a second amount of unscented low density polyethylene, for example, or polypropylene, for example. Usually, but not necessarily, the second amount of polymer is larger than the first amount. The resulting mixture thus obtained is solidified subsequent to or prior to ultimate casting into a utilitarian shape.

Thus, in accordance with one aspect of our invention the imparting of scent is effected in two stages. In a first stage, a 50:50 (weight:weight) polyepsilon caprolactone, e.g., PCL-700: polyethylene in molten form is admixed with a high percentage of one or more of the schiff base reaction products of our invention including compounds defined according to the structure: ##STR74## and the mixture is solidified in the form of pellets or beads. These pellets or beads thus contain a high percentage of schiff base reaction product(s) (e.g., up to 45% by weight of the entire mixture) and may be used as "master pellets" which thereafter, in a second stage, if desired, may be admixed and liquified with additional polymers such as additional polyethylene or mixtures of polyethylene and polyepsilon caprolactone in an unscented state, or unscented polypropylene. In addition, additional polymers or copolymers may be used, for example, copolymers specified and described in United Kingdom Patent Specification No. 1,589,201 published on May 7, 1981, the specification for which is incorporated by reference herein.

In accordance with the present invention one or more of the schiff base reaction products of our invention is added to the polymer in a large closed container or drum which is maintained under controlled temperature conditions while the polymer in a melted condition is mixed with one or more of the schiff base reaction products including compounds defined according to the generic structure: ##STR75## wherein, R, R' and R" are defined, supra, under agitation.

In order that the perfume be added uniformly to the polymer, the temperature of the melt is constantly controlled during the process. The polymer-perfume mixture is then directed through an elongated conduit or pipe element having a plurality of orifices adjacent to the lower most portion thereof. The polymer enriched by one or more of the schiff base reaction products of our invention is permitted to drip through the orifices onto a continuously moving, cooled conveyor upon which the polymer containing one or more of the schiff base reaction products of our invention including compounds defined according to the structure: ##STR76## solidifies into small size pellets with the perfume imprisoned therein. The apparatus useful in conjunction with this process advantageously includes a conveyor of a material which will not adhere to the polymer which contains one or more of the schiff base reaction products of our invention.

In order that the droplets form into uniform pellets or beads, the conveyor is continuously washed with a liquid such as water to maintain the surface relatively cool. The pellets are delivered by the conveyor into a container and packaged for shipment.

In respect to augmenting or enhancing the aroma or taste of foodstuffs, chewing gums, toothpastes, medicinal products and chewing tobaccos, one or more of the schiff base reaction products of our invention including compounds defined according to the generic structure: ##STR77## wherein R, R' and R" are defined, supra, may augment or enhance grape, neroli, mandarine and tangerine flavored foodstuffs as a result of these schiff base reaction products having concord grape, floral, orange blossom and neroli aroma and taste nuances at from about 0.1 ppm up to about 100 ppm.

Thus, for example, one or more of the schiff base reaction products of our invention may be added in an amount of between about 0.1 ppm up to about 100 ppm of beverage, e.g., synthetic grape flavored beverage (e.g., KOOL-AID.RTM.) and the resulting product has an intense and substantive natural-like grape aroma and taste; much more natural than the original grape flavored KOOL-AID.RTM. product. TANG.RTM., orange-flavored beverage may have its orange-flavor augmented or enhanced by adding at a rate of from about 0.1 ppm up to about 100 ppm of one or more of the schiff base reaction products of our invention to the TANG.RTM. beverage thereby imparting a natural manderine and tangerine aroma and taste nuance to the otherwise plain-orange flavored beverage.

The following table indicates the nature of the schiff base reaction product and the organoleptic properties of the schiff base reaction products included in our invention:

CONDITIONING SHAMPOOS

Monamid CMA (prepared by the Mona Industries Company) (3.0 weight percent) is melted with 2.0 weight percent coconut fatty acid (prepared by Procter & Gamble Company of Cincinnati, Ohio); 1.0 weight percent ethylene glycol distearate (prepared by the Armak Corporation) and triethanolamine (a product of Union Carbide Corporation) (1.4 weight percent). The resulting melt is admixed with Stepanol WAT produced by the Stepan Chemical Company (35.0 weight percent). The resulting mixture is heated to 60.degree. C. and mixed until a clear solution is obtained (at 60.degree. C.). This material is "COMPOSITION A".

GAFQUAT.RTM.755N polymer (manufactured by GAF Corporation of 140 West 51st Street, New York, N.Y.) (5.0 weight percent) is admixed with 0.1 weight percent sodium sulfite and 1.4 weight percent polyethylene glycol 6000 distearate produced by Armak Corporation. This material is "COMPOSITION B".

The resulting "COMPOSITION A" & "COMPOSITION B" are then mixed in a 50:50 weight ratio of A:B and cooled to 45.degree. C. and 0.3 weight percent of perfuming substance as set forth in Table III of Example V is added to the mixture. The resulting mixture is cooled to 40.degree. C. and blending is carried out for an additional one hour in each case. At the end of the blending period, the resulting material has a pleasant fragrance as indicated in Table III of Example V.

EXAMPLE XIII

Each of the fragrance materials of Table III of Example V, supra, are added to a 50:50 weight:weight mixture of low density polyethylene:polyepsilon caprolactone PCL-700 forming pellets with scents as set forth in Table III of Example V, supra.

75 Pounds of a 50:50 mixture of PCL-700 polyepsilon caprolactone (manufactured by the Union Carbide Corporation of New York, N.Y. having a melting point of about 180.degree.-190.degree. F.): Low density polyethylene, are heated to about 250.degree. F. in a container of the kind illustrated in FIGS. 20 and 21. 25 Pounds of each of the fragrance materials as set forth in Table III of Example V, is then quickly added to the liquified polymer mixture, the lid 228 is put in place and the agitating means 273 are actuated. The temperature is then raised to about 260.degree. F. and the mixing is continued for 5-15 minutes. The valve "V" is then opened to allow flow of the molten polymer enriched with perfume ingredient to exit through the orifices 234. The liquid falling through the orifices 234 solidifies almost instantaneously upon impact with the moving cooled conveyor 238. Polymer beads or pellets 244 having pronounced scents as described in Table III of Example V, supra, are thus formed. Analysis demonstrates that the pellets contain about 25% of the perfume material so that almost no losses in the scenting substance did occur. These pellets may be called "master pellets".

50 Pounds of each batch of the scent containing "master pellets" are then added to one thousand pounds of unscented polypropylene 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 III of Example V, supra. The sheets of films are cut into strips of 0.25" in width.times.3" in length and placed into room air fresheners.

On operation of the room air freshener, after four minutes, the room in each case has an aesthetically pleasing aroma with no foul odor being present, the aroma being described in Table III of Example V, supra.
