Description

[Technical Field]

[0001] This invention relates to the field of fragrances. In particular, this invention relates to a consumer product comprising at least one compound of formula (I) and optionally a personal care active base. Furthermore, this invention relates to a method for imparting a long-lasting odor, particularly a green odor, to a surface such as skin or hair.

[0002] Background of the Invention The fragrance industry is interested in compositions or additives that can extend or enhance the fragrance effect of at least one fragrance component for a certain period of time. There is a particular desire for standard fragrance raw materials that are too volatile, have poor persistence on their own, or adhere only in small amounts to the surface of the end application to achieve long-lasting properties. Furthermore, some fragrance components are unstable and need to be protected from slow degradation before use. Long-lasting fragrances are desired for a variety of applications, such as fine or functional fragrances or cosmetic formulations.

[0003] To improve the long-lasting properties of fragrances, fragrance precursors, also known as pro-fragrances or pro-fragrances, have been extensively developed and used in this industry. The controlled release of at least one fragrance component from these precursors is triggered by covalent bond cleavage under mild environmental conditions. Laundry care applications have particularly desired these types of technologies because many active substances particularly suited to this type of application are known to lack tenacity during washing or do not remain on laundry after rinsing, resulting in their fragrance effect being short-lived and not very strong. Pro-fragrances developed for laundry care allow for the slow release of fragrance components over several days. However, other applications, such as leave-on applications, require the fragrance or fragrance composition to be effective for up to 24 hours. Due to this different time scale between the two types of applications, most fragrance precursors that are particularly effective for laundry care applications have less impact on leave-on applications. Therefore, there is a need to develop more versatile fragrance precursors that perform well in all types of applications.

[0004] Surprisingly, it was found that the compound of formula (I) solved the above problem and could efficiently release (2E,6Z)-nona-2,6-dien-1-ol in all types of applications, especially in leave-on applications. [Brief explanation of the drawing]

[0005] [Figure 1] This figure shows the analysis of the concentrations of 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate and (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate in solution over time. [Figure 2] This figure shows the analysis of the concentration of ethyl hexadecanate released from 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate and (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate in solution over time. [Figure 3] This figure shows the analysis of the concentrations of 3,7-dimethyl-2,6-octadiene-1-ol and (2E,6Z)-nona-2,6-diene-1-ol in the sample headspace after 4 hours on the surface, as a function of their respective ester concentrations: 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate and (2E,6Z)-nona-2,6-diene-1-ol. [Figure 4] This figure shows the analysis of the abundance of (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate, (2E,6Z)-nona-2,6-diene-1-yltetradecanoate, (2E,6Z)-nona-2,6-diene-1-yldodecanoate, and (2E,6Z)-nona-2,6-diene-1-ylbenzoate in the headspace after 4 hours of evaporation on the surface. [Figure 5] This figure shows the analysis of the abundance of (2E,6Z)-non-2,6-dien-1-ol in the personal care base in the headspace after 4 hours of evaporation from the surface (in the presence of hydrolase at a physiologically relevant concentration (0.1 LU / ml)). [Figure 6] This figure shows a panel for measuring the performance of 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate, (Z)-3-hexene-1-ylhexadecanoate, and (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate on a glass slide at 0.1 LU / ml after 4 hours. [Figure 7] This figure shows the forced selection sensory evaluation of 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate, (Z)-3-hexen-1-ylhexadecanoate, and (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate on a glass slide at 0.1 LU / ml after 4 hours.

[0006] Description of the present invention Surprisingly, it was found here that the compound of formula (I) is particularly efficient at releasing (2E,6Z)-nona-2,6-dien-1-ol in a controlled manner and on a timescale particularly suitable for leave-on applications.

[0007] Therefore, the first object of the present invention is, A flavored consumer product, a) Formula (I) in any one form of the stereoisomer, or as a mixture thereof [ka] [In the formula, R is linear or branched saturated or unsaturated C] 7~24 [Represents an alkyl group] A fragrance oil containing at least one compound of, b) Optionally, Personal Care Activation Base and It is a flavored consumer product that includes [the specified ingredient].

[0008] For clarity, the expression "one of its stereoisomers or a mixture thereof" or similar means in the ordinary sense as understood by those skilled in the art, i.e., the compound of formula (I) may be a pure enantiomer or diastereomer. In other words, the compound of formula (I) may have several stereocenters, in particular R groups, each of which may have two different stereochemistrys (e.g., R or S), or the compound of formula (I) may have one or more double bonds, in particular R groups, each of which may be in the form of its E or Z isomer or a mixture thereof. The compound of formula (I) may be in the form of a pure enantiomer (if chiral), a pure diastereoisomer (if two or more stereocenters or one or more double bonds), or even a mixture of enantiomers or diastereoisomers. The compound of formula (I) may be in racemic or scalemic form. Thus, the compound of formula (I) may be a single stereoisomer, or may contain various stereoisomers, or may be in the form of a composition of these substances.

[0009] According to any embodiment of the present invention, R may be a linear, saturated or unsaturated C 9~21 alkyl group. In particular, R may be a linear saturated C 10~18 alkyl group. In particular, R may be a linear saturated C 11~16 alkyl group. In particular, R may be a linear saturated C 11 alkyl group, a linear saturated C 13 alkyl group or a linear saturated C 15 alkyl group.

[0010] According to any embodiment of the present invention, the compound of formula (I) may be (2E,6Z)-nona-2,6-dien-1-yl hexadecanoate, (2E,6Z)-nona-2,6-dien-1-yl tetradecanoate or (2E,6Z)-nona-2,6-dien-1-yl dodecanoate.

[0011] Here, "perfume oil" means a component or composition that is liquid at about 20 °C. According to any one of the above embodiments, the perfume oil may be only the compound of formula (I), or a mixture of components currently used in perfumes, such as a perfume carrier, a perfume co-component and / or a perfume adjuvant. [[ID=2,3]]

[0012] Here, "perfume carrier" means a material that is substantially neutral from the perspective of perfume, that is, a material that does not significantly change the functional properties of the perfume component. The carrier may be liquid or solid.

[0013] Examples of liquid carriers, though not limited, include emulsions, i.e., solvents and surfactants, or solvents commonly used in fragrances. A detailed description of the properties and types of solvents commonly used in fragrances cannot be exhaustive. However, some of the most commonly used solvents, though not limited, include butylene or propylene glycol, glycerol, dipropylene glycol and its monoethers, 1,2,3-propanetriyltriacetate, dimethyl glutarate, dimethyl adipate, 1,3-diacetyloxypropane-2-yl acetate, diethyl phthalate, isopropyl myristate, benzyl benzoate, benzyl alcohol, 2-(2-ethoxyethoxy)-1-ethanol, triethyl citrate, or mixtures thereof. For compositions containing both a fragrance carrier and a fragrance base, other suitable fragrance carriers other than those previously specified may include ethanol, water / ethanol mixtures, limonene or other terpenes, isoparaffins such as those known as trademark Isopar® (manufactured by Exxon Chemical), glycol ethers and glycol ether esters such as those known as trademark Dowanol® (manufactured by Dow Chemical Company), or hydrogenated castor oil such as those known as trademark Cremophor® RH 40 (manufactured by BASF).

[0014] The term "solid carrier" is intended to refer to a material to which a fragrance composition or several elements of a fragrance composition can be chemically or physically bound. Generally, such solid carriers are used to stabilize a composition or to control the evaporation rate of a composition or several components. Solid carriers are currently used in the art, and those skilled in the art know how to achieve the desired effect. However, non-limiting examples of solid carriers include porous polymers, cyclodextrins, wood-based materials, organic or inorganic gels, clays, gypsum talc, or zeolites, which are absorbent gums or polymers or inorganic materials.

[0015] Other non-limiting examples of solid carriers include encapsulating materials. Examples of such materials include wall-forming and plasticizing materials such as monosaccharides, disaccharides or trisaccharides, natural or modified starches, hydrophilic colloids, cellulose derivatives, polyvinyl acetates, polyvinyl alcohols, proteins or pectin, or materials cited in reference texts such as H. Scherz, Hydrokolloide: Stabilisatoren, Dickungs- und Geliermittel in Lebensmitteln, Band 2 der Schriftenreihe Lebensmittelchemie, Lebensmittelqualitaet, Behr's Verlag GmbH & Co., Hamburg, 1996. Encapsulation is a process well known to those skilled in the art and may be carried out, for example, by using techniques such as spray drying, agglomeration or even extrusion; or it may consist of coating encapsulation including coacervation and composite coacervation techniques.

[0016] Non-limiting examples of solid supports include core-shell capsules made of aminoplasts, polyamides, polyesters, polyureas, or polyurethane-type resins or mixtures thereof (all of which are well known to those skilled in the art), using techniques such as a phase separation process induced by polymerization, interfacial polymerization, coacervation, or all of the above, optionally in the presence of a polymeric stabilizer or cationic copolymer (all of which are described in the prior art).

[0017] The resin may be produced by polycondensation of amines such as urea, benzoguanamine, glycoluryl, melamine, methylolmelamine, methylated methylolmelamine, guanazole, and the like, and mixtures thereof, with aldehydes (e.g., formaldehyde, 2,2-dimethoxyethanal, glyoxal, glyoxylic acid, or glycolaldehyde, and mixtures thereof). Alternatively, pre-molded resin alkylolated polyamines, such as those commercially available under trademarks Urac® (manufactured by Cytec Technology Corp.), Cymel® (manufactured by Cytec Technology Corp.), Urecoll®, or Luracoll® (manufactured by BASF), can be used.

[0018] Other resins are produced by polycondensation of polyols such as glycerol with polyisocyanates such as a trimer of hexamethylene diisocyanate, a trimer of isophorone diisocyanate or xylylene diisocyanate, or a biuret of hexamethylene diisocyanate or a trimer of xylylene diisocyanate with trimethylolpropane (known by the trade name Takenate®, manufactured by Mitsui Chemicals). Among these, the trimer of xylylene diisocyanate with trimethylolpropane and the biuret of hexamethylene diisocyanate are preferred.

[0019] Some of the most important literature on the encapsulation of fragrances by polycondensation of aldehydes with amino resins, i.e., melamine-based resins, includes papers such as those published by K. Dietrich et al. in Acta Polymerica, 1989, vol. 40, pages 243, 325 and 683, and 1990, vol. 41, page 91. Such papers already describe various parameters that affect the preparation of such core-shell microcapsules following prior art methods, which are also further detailed and illustrated in the patent literature. U.S. Patent No. 4396670 by Wiggins Teape Group Limited is an early example of the latter. Since then, many other authors have enriched the literature in this field, and it would be impossible to cover all published developments here, but a general understanding of encapsulation techniques is very important. More recent relevant publications disclosing suitable uses for such microcapsules are represented, for example, by the article K. Bruyninckx and M. Dusselier, ACS Sustainable Chemistry & Engineering, 2019, vol. 7, pages 8041-8054.

[0020] Here, “fragrance co-component” means a compound used in a fragrance preparation or composition to impart a pleasurable effect. In other words, such co-components considered to be fragrance co-components should be recognized by those skilled in the art not merely as having an odor, but as being capable of positively or pleasantly imparting or modifying the odor of a composition. The fragrance co-component is not of formula (I).

[0021] Herein, the properties and types of fragrance components present in the composition are not guaranteed to be exhaustive (and will not be exhaustive in any case), and those skilled in the art can select them according to their intended use or application and desired sensory effect based on their general knowledge. Generally speaking, these fragrance components belong to various chemical classifications such as alcohols, lactones, aldehydes, ketones, esters, ethers, acetates, nitriles, terpenoids, nitrogen-containing or sulfur-containing heterocyclic compounds and essential oils, and these fragrance components may be of natural or synthetic origin.

[0023] The flavored consumer products of the present invention may further include other flavoring co-components listed in reference texts such as the book *Perfume and Flavor Chemicals*, 1969, Montclair, New Jersey, USA by S. Arctander, or more recent editions thereof, or other works of a similar nature, as well as in the extensive patent literature in the field of fragrances. It is also understood that the co-components may be compounds known to release various types of flavoring compounds, also known as pro-fragrances or pro-scents, under controlled conditions.

[0024] Here, "fragrance adjuvants" refer to ingredients that can impart additional benefits such as color, specific lightfastness, and chemical stability. A detailed description of the properties and types of adjuvants commonly used in fragrance compositions cannot be exhaustive, but it should be noted that such ingredients are well known to those skilled in the art. Specific non-limiting examples include: viscosities (e.g., surfactants, thickeners, gelling and / or rheological modifiers), stabilizers (e.g., preservatives, antioxidants, heat / light and / or buffering or chelating agents, e.g., BHT), colorants (e.g., dyes and / or pigments), preservatives (e.g., antibacterial or antimicrobial or antifungal or anti-irritant agents), abrasives, skin coolants, fixatives, insecticides, ointments, vitamins, and mixtures thereof.

[0025] Those skilled in the art will understand that by mixing the above-mentioned components of the perfume oil, by simply applying standard knowledge in the art, and by trial and error, it is possible to perfectly design a perfume oil formulation that is optimal for the desired effect.

[0026] A fragrance oil comprising at least one compound of formula (I) and at least one fragrance carrier comprises a fragrance oil containing at least one compound of formula (I) as in a specific embodiment of the present invention, at least one fragrance carrier, at least one fragrance cocomponent, and optionally at least one fragrance adjuvant.

[0027] According to a particular embodiment, the above-described fragrance oil comprises one or more compounds of formula (I), enabling a perfumer to prepare accords or fragrances with the olfactory properties of various compounds of the present invention, and thus to create new components for creative purposes.

[0028] For clarity, it is also understood that any mixture resulting directly from a chemical synthesis in which the compound of formula (I) is involved as a starting, intermediate, or final product, such as an unpurified reaction medium, cannot be considered a fragrance composition according to the present invention unless the mixture provides the compound of formula (I) in a form suitable for fragrance. Therefore, unpurified reaction mixtures are generally excluded from the present invention unless otherwise specified.

[0029] To clarify, “Fragrant consumer products” are intended to refer to consumer products that, among various benefits, are expected to deliver a pleasant fragrance effect to the surface or space to which they are applied (e.g., skin, hair, textiles, paper, or residential surfaces) or into the air (e.g., air fresheners, deodorizers). In other words, a fragrance consumer product according to the present invention is an industrial product comprising a functional formulation, also called a “base,” corresponding to the desired consumer product, which together contains beneficial agents, and at least one compound of formula (I) in an olfactory effective amount. To clarify, said fragrance consumer products are non-edible products.

[0030] Herein, the properties and types of components of the flavored consumer products are not intended to provide a more detailed description (and will not be exhaustive in any case), and those skilled in the art can select them according to the properties of the product and the desired effect based on their general knowledge.

[0031] Suitable fragranced consumer products include, but are not limited to, fragrances such as fine fragrances, splashes or eau de parfums, colognes or shave or aftershave lotions; body care products such as hair care products (e.g., shampoos, coloring formulations or hair sprays, color care products, hair styling products), dental care products, disinfectants, and intimate care products; cosmetic formulations (e.g., skin creams or lotions, vanishing creams or deodorants or antiperspirants (e.g., sprays or roll-ons), depilators, tanning or sun or after-sun products, nail products, skin cleansers, and makeup); or skincare products (e.g., soaps, shower or bath mousses, oils or gels, or hygiene products or foot / hand care products).

[0032] According to certain embodiments, flavored consumer products are leave-on consumer products.

[0033] The term "leave-on consumer product" or similar means that the consumer product is intended to maintain prolonged contact with the skin, hair, or mucous membranes, as opposed to rinse-off consumer products.

[0034] Non-exclusive examples of suitable flavored leave-on consumer products include: -Fragrances such as fine fragrances, splashes, eau de toilette, eau de parfum, cologne, or shave or aftershave lotion; - Hair care products such as hair creams, hair oils, hair styling products (sprays, mousses, or gels, etc.), leave-on hair conditioners, and hair tonics; - Skin care products such as facial creams, facial lotions, shaving products (such as foams, creams, gels or oils), body and / or hand products (such as lotions, creams, gels or oils), skin farming products, depilatory agents, talcum powders, foot care creams or lotions, baby wipes, cleansing wipes, moisturizer wipes, sun protection products (such as sprays, lotions, creams or oils), aftersun lotions, or self-tanning products; - Body deodorant or antiperspirant products such as body deodorant sprays, roll-on deodorants, deodorant sticks, deodorant creams, antiperspirant sprays, antiperspirant sticks, roll-on antiperspirants, antiperspirant sticks, or antiperspirant creams; Here, the personal care active base means a component capable of imparting benefits related to personal consumer products such as texture, moisturizing agents, etc. Personal care active bases capable of incorporating the compounds of formula (I) can be found in the extensive literature on such products. Here, these formulations are not guaranteed to be detailed (nor will they be comprehensive in any case). One skilled in formulating such consumer products can fully select suitable components based on their general knowledge and the available literature.

[0035] According to any embodiment of the present invention, the perfumed consumer product may be in the form of a perfume. In particular, the perfumed consumer product may be in the form of a fine fragrance, splash, eau de toilette, eau de parfum, cologne or shave or aftershave lotion.

[0123] Palmitoyl chloride (20 g, 72.7 mmol) dissolved in 50 ml of CH2Cl2 was added dropwise over 1 hour to a cold (ice bath) CH2Cl2 (150 ml) solution of triethylamine (8.1 g, 80 mmol), 4-dimethylaminopyridine (1.8 g, 14.7 mmol), and (2E,6Z)-nona-2,6-dien-1-ol (12.3 g, 87.4 mmol). The reaction mixture was removed from the cold bath and stirred at room temperature for 20 hours. The mixture was carefully poured into 1 M HCl (300 ml) and then extracted with diethyl ether (2 × 300 ml). The combined organic phases were washed with water, saturated Na2CO3, and water. The combined organic phases were dried over Na2SO4, filtered, and concentrated. The resulting material was subjected to flash chromatography (silica gel, hexane / siRNA, 100:0~98:2) to obtain 20.2 g (53.3 mmol, 73% yield) of (2E,6Z)-nona-2,6-dien-1-ylhexadecanoate as a pale yellow oil.

[0124] [ka]

[0125] Methyl palmitate, (2E,6Z)-nona-2,6-dien-1-ol, and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) were added to a 100 ml flask equipped with a distillation head. The mixture was heated in an oil bath at 150°C for 4 hours while distilling MeOH from the flask. Excess pelargodienol was removed from the reaction mixture by vacuum distillation (vapor temperature 50-55°C, 20 mTorr). The remaining residue was diluted with ethyl acetate and washed with water (3×). The organic phase was dried over Na₂SO₄, filtered, and concentrated. The residue was further concentrated by heating under vacuum (200°C, 20 mTorr) to remove residual methyl palmitate. The material was then dissolved in diethyl ether and filtered through a silica gel bed. The solution was concentrated under vacuum to obtain 9.51 g (52% yield) of (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate as a pale amber oil.

[0132] Example 2 Reaction rate measurement (in solution) of the compound of the present invention and comparative compounds. The release kinetics of 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate (comparative compound) and (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate (compound of the present invention) in the presence of hydrolase were compared.

[0133] To compare the reaction rates of the esters, the amounts of 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate and (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate, as well as the amount of ethyl hexadecanoate, were measured over time by GC / MS. Ethyl hexadecanoate was produced by the reaction between the released hexadecanoic acid and ethanol.

[0134] Enzyme solution preparation: The lipase enzyme source used was Enzyme Innovation Addclean LP L with an activity of 20,000 lipase units / g. A 100 LU / ml stock solution was prepared and diluted to working concentrations by serial dilutions as follows: [Table 1]

[0135] A solution containing 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate or (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate (also called palmitate solution) was prepared by dissolving it in ethanol to 5% by weight. Subsequently, these solutions were diluted to the experimental working conditions.

[0136] 50 µl of 100 LU / ml solution was added to a 2 ml Agilent GC vial (Agilent 5183-2068) using a micropipette. 100 µl of deionized water was added to continue the hydrolysis. Samples were prepared for each time condition, repeat, and for the palmitate ester solution of interest, because the reaction stopped at 0, 0.5, and 1 hour and was measured only once. Two additional samples were prepared as negative controls using only 150 µl of deionized water.

[0137] Palmitic acid ester was prepared by dissolving it in ethanol to 5% by weight (stock). The palmitic acid ester solution was further diluted to 0.2%, and 50 μl was added to all of the above sample vials, with time recorded as zero. The sample vials were left open to the atmosphere on a high-precision hot plate preheated to 32°C. At 0 hours, 0.5 hours, and 1 hour, 800 μl of ethanol was added to each of the vials to stop the reaction. The vials were closed and mixed by shaking. The samples were analyzed by GC / MS direct injection as follows.

[0138] GC-MS analysis was performed using an Agilent Gas Chromatograph system 7890B coupled to an Agilent Mass Selective Detector 5977B and equipped with a Gerstel MPS autosampler or equivalent. Chromatographic separation was achieved using an Agilent J&W DB-1ms Ultra Inert Capillary GC Column [part number 121-0122UI] with a length of 20 m, an inner diameter of 0.18 mm, and a film thickness of 0.18 μm. Volatile material was eluted at a constant flow rate of 1.2 mL / min using helium, with a temperature gradient increasing at a rate of 15 °C / min from 50 °C (held for 2 minutes) to 300 °C and a final holding time of 2 minutes (giving a total test time of 20.667 minutes). The solution preparation was injected by injecting 1 μL into the Agilent inlet (inlet 1) using a 10 μL syringe. An Agilent 5190-2293 inlet liner was inserted into inlet 1, and splitless mode was used with an injector set to 250°C. The mass spectrometer was operated in scan mode for masses from 48 to 350. External calibration curves for (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate and 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate were prepared at 10 to 500 ppm, and the sample signals were quantified in ppm. The analysis yielded results as shown in Figures 1 and 2.

[0139] As shown in Figure 1, the concentration of (2E,6Z)-nona-2,6-dien-1-ylhexadecanoate in solution decreased more rapidly than the concentration of 3,7-dimethyl-2,6-octadien-1-ylhexadecanoate. As the released hexadecanoic acid reacted with ethanol present in the solution, the increase in ethyl hexadecanoate resulted in the faster release of (2E,6Z)-nona-2,6-dien-1-ol compared to 3,7-dimethyl-2,6-octadien-1-ol, as shown in Figure 2.

[0140] The combination of a faster depletion of the reactants and a faster accumulation of ethyl hexadecanate results in a higher total lipase catalytic reaction rate for (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate than for 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate.

[0141] Example 3 Fragrance generation in Tzero Lids (Dynamic Headspace) using the compounds of the present invention and comparative compounds. To further investigate the release kinetics of palmitate esters in the presence of hydrolase, we devised an in-vitro assay to measure functional fragrance components in the gas phase.

[0142] Three palmitic acid esters releasing (2E,6Z)-nona-2,6-dien-1-ol (corresponding to the compound of the present invention) and 3,7-dimethyl-2,6-octadien-1-ol (corresponding to the comparative compound), respectively, were tested in the presence of hydrolase (0.1 LU / ml) at physiologically relevant concentrations as follows: 2.5 ul of lipase solution (0.100 LU / ml) was added to a Tzero Lids TA [part number 901671.901] crucible. 2.5 ul of 0%, 0.5%, 0.1%, 0.5%, and 1% solutions of palmitic acid esters in ethanol were added to the same crucible and placed on a high-precision hot plate preheated to 32°C. Additional aliquots of 2.5 ul of water were added to the crucible at 1 hour and 4 hours to simulate moisture on skin and facilitate hydrolysis. After X hours at 32C, the crucible was transferred to a 20 ml headspace vial.

[0143] The analysis performed using Dynamic Headspace with a Tenax TA trap was summarized as follows: GC-MS-DHS analysis was performed on an Agilent Gas Chromatograph system 7890B coupled to an Agilent Mass Selective Detector 5977B and equipped with a Gerstel MPS autosampler. In addition, an automated Gerstel Dynamic Headspace System setup was used, including an ATEX air sampling tube gripper for a 20 mL headspace vial with a metal screw cap (assembled with a 1.3 mm PTFE septum), and a Gerstel CIS 4C cryogenic cooler CCD2 (Inlet 2) fitted with a Gerstel TDU2 thermal desorption unit. The purge and trap dynamic headspace technique was used to perform GC headspace analysis with a purge volume of 20 mL at a rate of 100 mL / min at 32°C and a trap volume of 30 mL at a rate of 5 mL / min at 32°C. The TDU desorption mode was set to splitless to desorb a TDU tube Tenax TA Gerstel 020810-005-00 or Supelco 6484U air sampling trap in TDU2, using a temperature gradient rising from 25°C (held for 0.3 minutes) to 270°C at a rate of 240°C / min and a final holding time of 5 minutes. A CIS 4C Gerstel Tenax TA 013247-005-00 or Supelco 6823-U liner was used with a temperature gradient rising from -10°C (held for 0.5 minutes) to 300°C at a rate of 12°C / min and a final holding time of 10 minutes. The solvent vent mode was used with a purge flow rate of 50 mL / min at 7 minutes and a vent flow rate of 50 mL / min until 0 minutes. Chromatographic separation was achieved using an Agilent J&W DB-1ms Ultra Inert Capillary GC Column [part number 121-0122UI] with a length of 20 m, an inner diameter of 0.18 mm, and a film thickness of 0.18 μm. Volatile material was eluted at a constant flow rate of 1.2 mL / min using helium with the following oven temperature program: 50°C (held for 2 minutes) was increased to 300°C at a rate of 10°C / min and a final holding time of 3 minutes.The mass spectrometer was operated in scan mode for masses between 48 and 350.

[0144] The controls are (2E,6Z)-nona-2,6-dien-1-ol (corresponding to the compound released from the compound of the present invention) and 3,7-dimethyl-2,6-octadien-1-ol (corresponding to the compound released from the comparative compound) by weight equivalent.

[0145] A standard curve is created by diluting and spiking the control using a blank Tenax trap.

[0146] Figure 3 shows the results for alcohol released in headspace over 4 hours.

[0147] It was observed that (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate releases fragrance material to it at a higher rate than 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate.

[0148] Example 4 Fragrance generation in Tzero Lids (Dynamic Headspace) using the compounds of the present invention and comparative compounds. To further investigate the effect of the "R" group on the release kinetics of esters in the presence of hydrolase, we devised an in-vitro assay to measure functional fragrance components in the gas phase.

[0149] Four esters releasing (2E,6Z)-nona-2,6-dien-1-ol (corresponding to the compound of the present invention) were tested: (2E,6Z)-nona-2,6-dien-1-ylhexadecanoate, (2E,6Z)-nona-2,6-dien-1-yltetradecanoate, (2E,6Z)-nona-2,6-dien-1-yldodecanoate, and (2E,6Z)-nona-2,6-dien-1-ylbenzoate (comparative compound). The tests were performed in the presence of hydrolase at physiologically relevant concentrations (0.1 LU / ml) as follows: 2.5 ul lipase solution (0.100 LU / ml) was added to a Tzero Lids TA [part number 901671.901] crucible. A 2.5 µl 1% solution of palmitate ester in ethanol was added to the same crucible and placed on a high-precision hot plate preheated to 32°C. Additional aliquots of 2.5 µl of water were added to the crucible at 1 hour and 4 hours to simulate moisture on skin and facilitate hydrolysis. After 4 hours at 32°C, the crucible was transferred to a 20 ml headspace vial.

[0151] The control is (2E,6Z)-nona-2,6-dien-1-ol by weight equivalent (corresponding to the compound released from the compound of the present invention). A standard curve is created by diluting and spiking the control in a blank Tenax trap.

[0152] Figure 4 shows the results of (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate, (2E,6Z)-nona-2,6-diene-1-yltetradecanoate, (2E,6Z)-nona-2,6-diene-1-yldodecanoate, and (2E,6Z)-nona-2,6-diene-1-ylbenzoate releases of (2E,6Z)-nona-2,6-diene-1-ol in headspace over 4 hours.

[0153] C 11 Linear alkyl chain, C 13 It was observed that compounds having an R group that is a linear alkyl chain or a C15 linear alkyl chain release (2E,6Z)-nona-2,6-dien-1-ol, while compounds having an R group that is a benzoate do not release it.

[0154] Example 5 Fragrance generation of the compound of the present invention in Tzero Lids (Dynamic Headspace) within a personal care base.

[0155] To confirm fragrance release in the presence of the personal care base, the personal care base was combined with the compound of the present invention and analyzed by an in-vitro assay measuring the functional fragrance components in the gas phase.

[0156] [Table 2]

[0157] The experiment was conducted in the presence of hydrolase at a physiologically relevant concentration (0.1 LU / ml) as follows: 2.5 UL of lipase solution (0.100 LU / ml) was added to a Tzero Lids TA [part number 901671.901] crucible. 2.5 UL of personal care base containing (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate was added to the same crucible and placed on a high-precision hot plate preheated to 32°C. Additional aliquots of 2.5 UL of water were added to the crucible at 1 hour and 4 hours to simulate moisture on the skin and facilitate hydrolysis. After 4 hours at 32°C, the crucible was transferred to a 20 ml headspace vial.

[0158] The analysis performed using Dynamic Headspace with a Tenax TA trap was summarized as follows: GC-MS-DHS analysis was performed on an Agilent Gas Chromatograph system 7890B coupled to an Agilent Mass Selective Detector 5977B and equipped with a Gerstel MPS autosampler.

The purge and trap dynamic headspace technique was used to perform GC headspace analysis with a purge volume of 20 mL at a rate of 100 mL / min at 32°C and a trap volume of 30 mL at a rate of 5 mL / min at 32°C. The TDU desorption mode was set to splitless to desorb a TDU tube Tenax TA Gerstel 020810-005-00 or Supelco 6484U air sampling trap in TDU2, using a temperature gradient rising from 25°C (held for 0.3 minutes) to 270°C at a rate of 240°C / min and a final holding time of 5 minutes. A CIS 4C Gerstel Tenax TA 013247-005-00 or Supelco 6823-U liner was used with a temperature gradient rising from -10°C (held for 0.5 minutes) to 300°C at a rate of 12°C / min and a final holding time of 10 minutes. The solvent vent mode was used with a purge flow rate of 50 mL / min at 7 minutes and a vent flow rate of 50 mL / min until 0 minutes. Chromatographic separation was achieved using an Agilent J&W DB-1ms Ultra Inert Capillary GC Column [part number 121-0122UI] with a length of 20 m, an inner diameter of 0.18 mm, and a film thickness of 0.18 μm. Volatile material was eluted at a constant flow rate of 1.2 mL / min using helium with the following oven temperature program: 50°C (held for 2 minutes) was increased to 300°C at a rate of 10°C / min and a final holding time of 3 minutes.The mass spectrometer was operated in scan mode for masses between 48 and 350.

[0159] The control is (2E,6Z)-nona-2,6-dien-1-ol by weight equivalent (corresponding to the compound released from the compound of the present invention). A standard curve is created by diluting and spiking the control in a blank Tenax trap.

[0160] Figure 5 shows the results of (2E,6Z)-nona-2,6-dien-1-ol release from (2E,6Z)-nona-2,6-dien-1-ylhexadecanoate in a personal care base containing a physiologically relevant concentration of hydrolase (0.1 LU / ml). No release was observed in the absence of hydrolase (water control).

[0161] Example 6: Panel of released fragrance alcohol on a glass slide Evaporation kinetics were performed using 76 mm × 51 mm glass slides. A Prazitherm high-precision hot plate was preheated to 32 degrees Celsius for 30 minutes. Three glass slides were placed on the high-precision hot plate. Each glass slide was labeled with a unique code to prevent its identity from being known to the panelists. Using a Gilson Microman M25 volumetric pipette, 20 μl of 0.1 LU lipase solution was directly delivered to the center of one of the glass slides. Then, 20 μl of 1% (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate was very slowly delivered onto the lipase droplet. After all sample solutions had been applied to the glass slides, the applied glass slides were evaporated on the high-precision hot plate at 32 degrees Celsius for 4 hours. Sample preparations for 1% (Z)-3-hexen-1-ylhexadecanoate solution and 1% 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate solution were carried out in the same manner. Sample preparations for all three solutions were repeated for pairs, and each glass slide was changed twice during the sensory evaluation panel period—the limit of the glass slide sample set (for three different glass slide samples) was 10 evaluations. At 4-hour time intervals, spray bottles filled with deionized water were primed, and then water was sprayed directly onto each glass slide once. One spray was sufficient to cover the glass slide. All glass slides were left to stand for 10 minutes before the sensory evaluation panel, so that the water could be absorbed by the evaporated mixture, replacing the moisture on the surface. For evaluation, panelists picked up the treated glass slides, smelled the center, and rated the intensity of each slide on an evaluation sheet.

[0162] In a single test, panelists rated the odor intensity of each glass slide, evaluated under hydrolase release for 4 hours, on a scale of 1 to 7. The results are shown in Figure 6.

[0163] The second approach was a so-called forced selection, in which panelists were compelled to select the strongest of three hexanoic acid esters after release by hydrolase at 0.1 LU / ml for 4 hours. The results are shown in Figure 7.

[0164] (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate was observed to be significantly stronger than 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate or (Z)-3-hexene-1-ylhexadecanoate.

[0165] When forced to choose, 20 out of 21 panelists selected (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate as the strongest sample. (Z)-3-hexene-1-ylhexadecanoate was also observed to release faster than 3,7-dimethyl-2,6-octadiene-1-ylhexadecanoate, but this was not well perceived by the panelists. (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate was the compound that made the strongest impression.

[0166] Example 7 Performance of fine fragrances applied to the skin, containing compounds of formula (I) [Table 3-1] [Table 3-2]

[0167] To this fine fragrance formulation corresponding to fragrance A, 0.7 parts of (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate corresponding to fragrance B or 2 parts of (2E,6Z)-nona-2,6-diene-1-ylhexadecanoate corresponding to fragrance C were added.

[0168] Fragrances A-C were supplied at 18% by weight in ethanol / water (95:5). The fragrance solution was applied to the forearms of two subjects with three pump sprays (approximately 240 ul). The fragrances were left on for 6 hours, avoiding contact with clothing. After 6 hours of dry-down, evaluations were conducted by three trained evaluators and three professional (perfumer) evaluators, assessing the intensity and freshness of the fragrances.

[0169] All panelists found fragrance C to be the strongest and freshest, while fragrance A was the weakest in terms of both strength and freshness.
