The present invention relates to the field of perfumery. In particular, the compositions of the present invention have improved or enhanced fidelity and/or longevity of the fragrance profile, which is achieved by adding a specific sucrose based fragrance modulator as defined in the appended claims. Fragrance modulators do already exist, see e.g. [EP 1 186 289 A2](https://patents.google.com/patent/EP1186289A2) (TAKASAGO PERFUMERY CO LTD \[JP\]) 13 March 2002 (2002-03-13).

Previous attempts to overcome these problems have been through the use of various "fixatives" or "modulators" to retard the evaporation of the more volatile fragrance ingredients present in fragrance compositions. For instance, [U.S. Patent No. 4,313,855](https://patents.google.com/patent/US4313855) (Dragoco) describes the use in cosmetic compositions of 1-(2,6,6-trimethylcyclohexyl)-hexane-3-ol as an odourless fixative for increasing the perfume's intensity. [U.S. Patent No. 6,147,049](https://patents.google.com/patent/US6147049) (Givaudan) discloses a perfume fixative derived from tera-hydronaphthalenese for use in a wide range of fragrance compositions. [U.S. Patent No. 6,440,400B1](https://patents.google.com/patent/US6440400) (Takasago Perfumery) describes a composition using trimethylcyclohexane derivatives as perfuming-holding agents and melanin-formation inhibitors. [U.S. Patent No. 6,737,396B2](https://patents.google.com/patent/US6737396) (Firmenich) describes a perfume composition formed by mixing 2-30%, relative to the weight of the composition, of a fixative, (1-ethoxyethoxy)cyclododecane, to fix or exalt the musky or aromatic-type notes. [U.S. Patent No. 7,538,081](https://patents.google.com/patent/US7538081) (Takasago Perfumery) approaches the same problem of fixing a perfume and/or extending the perfume release from a fragrance composition. More particularly, said document describes the use of L-menthoxy ether derivatives as fixatives in fragrance compositions comprising at least one note selected from: floral, citrus, fruity, green, mint, herb and marine. JP Patent No. 61-083114 (Kanebo) describes ether derivatives as aroma-preserving agent for fine perfume composition. JP Patent No. 61-063612 (Kanebo) discloses diethylene glycol ether derivatives as fragrance adjusting agent showing effects as a fixative and a solubilizer. JP Patent No. 62-084010 (Shiseido) describes hydroquinone glycoside as perfume fixatives applicable for all kinds of perfume and blended perfume. On the other hand, PCT Publication No. WO85/04803 (Diagnostica) describes the use of hyaluronic acid/ hyaluronate as fixatives ( _via_ molecular encapsulation) in fragrance products to improve persistence of the fragrance. EP 1 186 289 describes fragrance compositions having excellent diffusivity and a long-lasting effect by incorporating a novel fixative in the composition, wherein the fixative is a 2-(L-menthoxy)alkanol derivative. EP 1 103 250 describes oil-in-polyhydric-alcohol type warming base agents containing a polyhydric alcohol, a sucrose fatty acid ester and an oil, having superior makeup removal effect, safety, stability and warming sensation. [WO 2014/090959](https://patents.google.com/patent/WO2014090959) discloses perfuming compositions that are free of ethanol in the form of transparent, clear microemulsions containing a fragrance, a solvent, non-ionic and ionic surfactants, a cooling hydrotrope and water. [US 2003/228334](https://patents.google.com/patent/US20030228334) relates to oil-in-water emulsions having a mattifying effect on the skin. The emulsions comprise a hydrophilic, non-organically modified magnesium aluminum silicate or a bentonite clay and a polyol in the water phase; and a volatile lipophilic solvent and a high melting point lipophilic plasticizer in the oil phase; and a surfactant system incuding non-toxic metal alkyl sulfates and/or sucrose esters. [DE 197 18 777](https://patents.google.com/patent/DE19718777) discloses the use of one or more di- or oligo-saccharide fatty acid esters as anti-adhesive agents against microorganisms, viruses, parasites and protozoa.


The inventors have surprisingly discovered a revolutionary new way of objectively classifying fragrance materials and then formulating those fragrance materials into complex fragrance mixtures having improved fragrance profile fidelity and longevity. Essentially, the solution is to formulate the fragrance materials having low levels (10 to 30 wt% relative to the total weight of the fragrance materials) of the low volatile fragrance materials in the presence of a substantially non-odorous fragrance modulator to provide for improved or enhanced longevity and/or fidelity of the fragrance profile, particularly amongst characters attributable to volatile fragrance materials. In fact, the inventors have discovered that in the complete absence of the low volatile fragrance materials or at very low levels of the low volatile fragrance materials (less than 10 wt% relative to the total weight of the fragrance materials), there is insufficient character complexity and roundness of the fragrance profile for consumer acceptance of the composition. Therefore the level of low volatile fragrance materials needs to be carefully chosen between 10 and 30 wt% to balance consumer acceptance and the desired improved or enhanced longevity and/or fidelity of the fragrance profile, particularly amongst characters attributable to volatile fragrance materials.


At the testing facility, 50 µL samples of the compositions and the controls are applied to glass slides and placed on a hot plate at 32 °C to represent skin temperature for varying durations. It is important that glass slides of samples that are to be later compared are prepared at the same time. The panelists are asked to evaluate the perceived fragrance profile (intensity and/or character) of each glass slide sample at a given time point. Slides are presented coded so that their identity is not known by the panelists. Within a given time point panelists evaluate the slides in a random order and are able to revisit their assessment as they work through the slides at that time point. Their assessments are recorded. In the subsequent analysis, the data for strength and character comparisons are drawn from the independent assessments carried out at a given time point. Only when using the character difference scale below are any 2 products physically directly compared to each other. Panelists are selected from individuals who are either trained to evaluate fragrances according to the scales below or who have experience with fragrance evaluation in the industry. Typically, around 6 to 10 panellists are used to evaluate a given product and its control.


The panelists are asked to give a score on a scale of 0 to 5 for perceived fragrance intensity according to the odour intensity scale set out in Table 4 herein below. Table 4 - Odour Intensity Scale


5\. Multiple glass capillaries are prepared in the same way and left to evaporate at ambient temperature for pre-determined periods of time, such as for example 10, 15, 30 mins, 1 hr, 2 hrs, 3 hrs, 4 hrs, 5 hrs, and up to 6 hrs, before being introduced to the headspace vial and sealed.


Compositions disclosed in Tables 18(a) and 19(a)-19(b) are applied to glass slides in accordance with the protocol described in the Method Section and a panel of around 6-10 experienced panelists evaluate the perceived fragrance profile at initial time 0, then at various time points, typically 1 hour, 2 hours, 3 hours, 4 hours and 6 hours post application. Panelists are asked to score the compositions for the longevity of the fragrance profile on a scale of 0 to 5, wherein 0 represents a no fragrance is detected and 5 represents a very strong fragrance intensity is detected; and for fragrance profile fidelity on a scale of 0 to 3 wherein 0 represents not detectable and 3 represents it being the dominant character. The results of the panelists are then averaged and discussed below.

Figure 1 shows the fragrance intensity profile of Composition R as evaluated by 10 panelists, which comprises the substantially non-odorous fragrance modulator sucrose myristate and the single fragrance material, ethyl safranate. Addition of the substantially non-odorous fragrance modulator maintains the intensity of the fragrance material for up to 6 hours whilst the control, Composition S, in the absence of the substantially non-odorous fragrance modulator, drops in fragrance intensity profile over the 6 hours. The substantially non-odorous fragrance modulator acts to maintain the continued evaporation over time of the fragrance material. Statistical analysis using the Tukey correction for multiple comparisons confirms the statistically significant difference at 0 hours (p = 0.0015), 1hour (p = 0.0033), 3hours (p = 0.0015) and 6 hours ((p = 0.0152) all at 95% significance level ( _i.e.,_ p < 0.05).

Addition of the substantially non-odorous fragrance modulator maintains the intensity of the fragrance material for up to 6 hours whilst the control, Composition Q, in the absence of the substantially non-odorous fragrance modulator, drops in fragrance intensity profile over the 6 hours. The substantially non-odorous fragrance modulator acts to maintain the continued evaporation over time of the fragrance material. Statistical analysis using the Tukey correction for multiple comparisons confirms the statistically significant difference at 1hour (p = 0.0581) at 90% significance level ( _i.e.,_ p < 0.1), 3hours (p = 0.0311) at 95% significance level ( _i.e.,_ p < 0.05).


Figure 3 shows the fragrance intensity profile of Composition T as evaluated by 10 panelists, which comprises the substantially non-odorous fragrance modulator sucrose myristate and the single fragrance material phenethyl alcohol (PEA). Addition of the substantially non-odorous fragrance modulator maintains the intensity of the fragrance material for up to 6 hours whilst the control, Composition U, in the absence of the substantially non-odorous fragrance modulator, drops in fragrance intensity profile over the 6 hours. The substantially non-odorous fragrance modulator acts to maintain the continued evaporation over time of the fragrance material. Statistical analysis using the Tukey correction for multiple comparisons confirms the statistically significant difference at 1 hour (p < 0.0001), 3 hours (p = 0.0016) and 6 hours (p= 0.0003) all at 95% significance level ( _i.e.,_ p < 0.05).


Figure 4 shows the fragrance intensity profile of Composition ZZ as evaluated by 11 panelists, which comprises the substantially non-odorous fragrance modulator hydroquinone beta-D-glycoside and the single fragrance material, eugenol. Addition of the substantially non-odorous modulator maintains the intensity of the fragrance material for up to 6 hours whilst the control, Composition ZZZ, in the absence of the substantially non-odorous fragrance modulator, drops in fragrance intensity profile over the 6 hours. The substantially non-odorous fragrance modulator acts to maintain the continued evaporation over time of the fragrance material. Statistical analysis using the Tukey correction for multiple comparisons confirms the statistically significant difference at 1 hour (p = 0.0008) and 3 hours (p = 0.0123) all at 95% significance level ( _i.e.,_ p < 0.05).


(b) Effects of the Substantially Non-Odorous Fragrance Modulators on the Fragrance Profile Longevity of Compositions having Reduced Levels of Low Volatile Fragrance Materials (between 10 to 30 wt% relative to the total weight of the Fragrance Materials) vs. Compositions having Traditional Levels of Low Volatile Fragrance Materials (Greater than 30 wt% relative to the total weight of the Fragrance Materials) and No Substantially Non-Odorous Fragrance Modulator- \[0119\]


Panelists are asked to score the compositions for the intensity of the fragrance on a scale of 0 to 5, wherein 0 represents no fragrance intensity is detected and 5 represents a very strong fragrance intensity is detected. The results of the panel test are then averaged. The results show the effect of the substantially non-odorous fragrance modulator and reduced levels of low volatile fragrance materials for any one of the inventive Compositions A, D, G, J and M on fragrance profile longevity versus control Compositions C, F, I, L and O in the absence of a substantially non-odorous modulator. Alternatively, the results show the effect of the substantially non-odorous fragrance modulator and reduced levels of low volatile fragrance materials for any one of the inventive Compositions A, D, G, J and M on fragrance profile longevity versus traditional Compositions B, E, H, K and N in the presence of the substantially non-odorous fragrance modulator.


Fragrance profile longevity, is maintained for up to at least 6 hours in the presence of the substantially non-odorous fragrance modulator whilst it drops in the absence of the substantially non-odorous fragrance modulator (data not shown). Without wishing to be bound by theory, it is believed that the substantially non-odorous fragrance modulator acts to maintain the continued evaporation over time of the fragrance materials, particular the volatile fragrance materials. The effect of the improved fragrance profile longevity of the present invention are noticeable at 1, 3 and 6 hours.


The test demonstrates the character retention over time of a fragrance composition. The results show the effect of the substantially non-odorous fragrance modulator and reduced levels of low volatile fragrance materials for any one of the inventive Compositions A, D, G, J, and M on fragrance profile longevity versus control Compositions C, F, I, L, and O, in the absence of the substantially non-odorous modulator. Alternatively, results show the effect of the substantially non-odorous fragrance modulator and reduced levels of low volatile fragrance materials for any one of the inventive Compositions A, D, G, J, and M on fragrance profile longevity versus traditional Compositions B, E, H, K, and N, in the presence of the substantially non-odorous fragrance modulator. Fragrance profile fidelity, particularly characters attributable to the volatile fragrance materials are maintained for up to at least 1 hour in the presence of the substantially non-odorous fragrance modulator whilst they drop in the absence of the substantially non-odorous fragrance modulator.


17. A method to enhance the fragrance profile of a composition, preferably improve the longevity of a character, preferably a floral character, of a composition, comprising bringing into contact or mixing at least one substantially non-odorous fragrance modulator with at least one low volatile fragrance material according to a composition as defined according to any one of claims 1-16.


According to an aspect of some embodiments of the present invention there is provided a scenting concentrate comprising: cis-3-hexenol at a concentration of at least 5 weight percents of the total weight of the concentrate; an ester of cis-3-hexenol having an evaporation number higher than 50 (a "heavy" ester, as described herein), at a concentration of at least 5 weight percents of the total weight of the concentrate; Galbanum resinoid at a concentration of at least 3 weight percent of the total weight of the concentrate; and an alcoholic carrier comprising at least one alcohol characterized by one or more of: a boiling temperature higher than 300 °C; substantivity of at least 300 hours; and evaporation number higher than 50, relative to diethyl ether.


According to some of any of the embodiments of the present invention, the odoriferous material imparts a base note of the ligneous hay odor (substantivity higher than 100 hours, or 200 hours and/or evaporation number higher than 50).


According to some of any of the embodiments of the present invention, the concentrate further comprises an odoriferous material that imparts a green or floral base note (e.g., characterized by substantivity higher than 200 hours and/or evaporation number higher than 50).


The formulation disclosed herein meets a long felt need in the field of artificial grasses and grass-related artificial products, as it imparts a long-lasting grass scent to the artificial grass or product. More specifically, the formulation disclosed herein imparts a grass scent that remains for at least 2 days, preferably for at least 3 days, at least 4 days, and even for at least 5 days or more. The formulation provided herein is


The scenting concentrate in the formulation provided herein comprises cis-3- hexenol (also known as cis-3-hexen-l-ol, and mainly as "leaf alcohol") as the main scenting ingredient that imparts a fresh grass scent. However, as cis-3-hexenol is a volatile compound, and features relatively low evaporation number and substantivity, the present inventors have devised and successfully prepared and practiced a concentrate and a formulation containing same, which comprise additional components that contribute to maintaining the fresh grass scent for a period of at least 48 hours.


By "long-lasting scenting effect" it is meant imparting a scent for a period longer than a few hours, namely, longer than 24 hours, 37 hours, 48 hours, 60 hours, 72 hours, 84 hours, 96 hours, and even longer than 100 hours.

The term "substantivity" is used herein and in the art of fragrances and perfumes to describe the persistence of a fragrant on the substrate to which it is applied. This term is typically reflected by the time period from application of a substance to a substrate during which the scent imparted by the substance persists, while considering conditions such as removal of the vehicle, contact with water, friction and the like. Values of substantivity provided in the art usually refer to a skin substrate, and consider also conditions to which the skin substrate is subjected to, such as sweating, swimming, bathing and the like. Substantivity of ingredients in a scenting formulation can be calculated according to methods known in the art and/or which can be found in public databases. Reference is made, for example, to www(dot)thegoodscentscompany(dot)com/data; Manuel Zarzo, Sensors, 2013, 13(l):463-483; and "Flavor, Fragrance and Odor analysis", Ed. Ray Marsilli, CRC Press, 29 Nov. 2001". Base notes typically have substantivity higher than 100 hours. Middle notes typically have substantivity of 10-100. Top notes typically have substantivity lower than 10.


According to some of any of the embodiments of the present invention, the ester of cis-3-hexenol is a "heavy" ester of cis-3-hexenol, characterized by high substantivity and/or high evaporation number. In some embodiments, the ester of cis-3-hexenol is characterized by substantivity higher than 100 hours, 150 hours or 200 hours. Due to its high substantivity, such a "heavy" ester imparts a base note of the formulation, for example, a green, floral or grass scent base note.


According to some of any of the embodiments of the present invention, additional "heavy" substances are included in the base formulation, for imparting a long-lasting scenting effect. These substances are characterized by substantivity higher than 100 hours, or higher than 200 hours, and even higher than 300 hours, and/or by evaporation number that is higher than 50, higher than 60 or higher than 70 (or from 35 to 100 or from 50 to 100). In some embodiments, such ingredients are present in the base formulation at a concentration ranging from 1 to 10 weight percents in total, or 3 to 7 weight percents in total.


In some embodiments the alcoholic base comprises one or more "heavy alcohols" characterized by substantivity higher than 100 hours, or higher than 200 hours or preferably higher than 300 hours, and/or by evaporation number higher than 60, higher than 70 or higher (or of from 50 to 100). Alternatively or additionally, the one or more "heavy alcohol" is characterized by a boiling temperature higher than 300 °C.

100 hours; 200 hours; 300 hours; 50 to 100


In some embodiments, such an odoriferous material is characterized by moderate to low substantivity (e.g., lower than 100 hours, or lower than 24 hours or lower than 10 hours), and/or moderate to low evaporation number (e.g., lower than 35,


Exemplary such odoriferous materials are aldehydes and alcohols of moderate to low substantivity (e.g., lower than 100 hours, or lower than 24 hours, or lower than 10 hours) and/or moderate to low evaporation number (e.g., lower than 35, or lower than 15, or lower than 10), such as, but not limited to, Dihydromyrcenol, Linalyle Acetate, and Styrallyl Acetate. In some embodiments, the formulation comprises one or more, or all of such odoriferous materials.


As discussed hereinabove, due to the long-lasting scenting effect provided by the formulations described herein, applying the formulation to a substrate can be effected by periodic intervals of 3 days or more. Any of the methods, systems and devices described herein can therefore be employed in accordance with these time intervals. Thus, for example, a controller in an exemplary system as described herein can operate the distribution system at periodic intervals of 3 days or more. The system also comprises a data processor which can be configured to vary the time intervals employed by the controller based on a predetermined criterion or set of criteria.


substantivity of at least 300 hours; and/or


substantivity higher than 100 hours; and/or


substantivity higher than 200 hours; and/or


There are at least one of several drawbacks to the above described classical formulation approach. Firstly, classification of fragrance materials by their characters is subjective and therefore results in inconsistency in the fragrance profile under classical fragrance pyramid construction rules. Secondly, the perceived intensity of the fragrance profile of the conventional perfume compositions, particularly those characters attributable to the more volatile fragrance materials, decreases rapidly over time due to their quick evaporation. Accordingly, conventional perfume compositions will typically change their overall fragrance profile over time. This is a problem because it is desirable to maintain "fragrance profile fidelity" over time. In other words, it is desirable to maintain the same or substantively similar fragrance profile for a commercial fragrance over time, particularly over long periods of time (at least 4 hrs, 6 hrs, or even 8 hours after application). Thirdly, with the classical fragrance pyramid construction, the possible types of fragrance profiles have been somewhat limited. The consequence of using base notes at high levels is that many fragrance dry-downs appear repetitive, boring, non-memorable and uninteresting to consumers. However, if base notes are reduced or excluded then the fragrance intensity weakens over time and does not last for a sufficient duration. Lastly, it is generally accepted that some consumers desire prolonged intensity of select characters, particularly the floral, spicy or aromatic characters derived from the heart notes. Unfortunately, the consequence of using high levels of base notes is that they may impart particularly undesirable characters, such as for example, musky, woody, ambery, warm and sweet, which overpower and dominate the more desirable fragrance characters over time, particular over long periods of time. Thus, the unique challenge remains of selectively extending the more desirable characters attributable from the heart and/or top notes, particularly the heart notes, and even more particularly extending these desirable characters over long periods of time.


Thus, it is an advantage of the present invention to provide new rules for objectively classifying fragrance materials according to their volatility using their their vapor pressures defined at suitable temperature, instead of their characters. The new rules operate irrespective of perfumers performing the classification. In particular, the new rules classify the fragrance materials into low, moderate or high volatile fragrance materials for formulating into fragrance mixtures, particularly ones having a diamond construction. It is a further advantage of the present invention to provide compositions having improved fidelity to the perceived fragrance profile over time. It is yet a further advantage to provide a composition, wherein the character attributable to moderate and high volatile fragrance materials, particularly the moderate volatile fragrance materials, remains significantly consistent from its initial impression to the end. It is yet a further advantage to provide compositions having improved longevity of the perceived fragrance profile, preferably the characters attributable from the moderate or high volatile fragrance materials, particularly the moderate volatile fragrance material. It is yet a further advantage to provide compositions having stable quality of end product ( _e.g.,_ fragrance profile, visual appearance) substantially comparable to the classical fragrance pyramid three-tiered structure, preferably even after three months storage at 40 °C. It is yet a further advantage to be able to create new to the world fragrance profiles wherein one, or several, well-recognized moderate volatile fragrance material characters, are maintained over time, preferably for long periods of time ( _e.g.,_ greater than 4, 6, or even 8 hours).


The present invention provides a method for imparting, intensifying, or modifying an odour on human skin or human hair, comprising applying to human skin and/or human hair the composition of the present invention. It is preferred that the method is for imparting, intensifying or modifying the longevity of a floral character or aromatic/spicy character on human skin or human hair, wherein the perceived intensity of the floral character or aromatic/spicy character at 1 hr, 2 hrs, 3 hrs or 6 hrs after application is greater than a control composition that does not include the substantially non-odorous fragrance modulator as determined by the panel method as disclosed herein.

Surprisingly, it was found that in particular the compounds of formula (I), and in particular compounds 1 to 8, are suitable as sandalwood-like fragrances. These compounds show additionally superior secondary properties, such as an elevated tenacity, a low odor threshold value, elevated impact (odor intensity), as well as an elevated substantivity.


- | TABLE 3 | | --- | | | | Comparison of the tenacity of compounds | | 1 to 3 according to formula (I). |


Therefore, among the above novel compounds specified in Table 1, compounds 1 to 4 are preferred due to their property to exhibit the most natural, the strongest and the most persistent sandalwood odor based on their high threshold intensity and superior tenacity, being superior to any existing synthetic, commercially available materials exhibiting a sandalwood odor, such as Brahmanol® (Symrise AG). However, compound 3 (2-ethyl-4-\[3-(methoxymethyl)-2,2-dimethyl-cyclopent-3-en-1-yl\]but-2-en-1-ol) is particularly preferred, showing the best olfactoric properties of the above indicated compounds as demonstrated in Tables 2 and 3.


In particular, it was found, that the compounds of formula (I) in general and in particular, compounds 1 to 4 are particularly excellent for imparting, modifying and/or enhancing a woody sandalwood-like fragrance being confusingly similar to the odor profile of natural sandalwood essential oil. The fact that the compounds have such an expressive scent and long tenacity is surprising. Furthermore, the combination of high intensity and tenacity allows for the use of said compounds and composition to achieve a pleasant odor in conjunction with an improved fixation of a fragrance compound resulting in an harmonic and long-lasting overall odor impression with the reminiscence of natural sandalwood, applicable for various perfumed products and for the production thereof.
