20210032561
Inventive subject matter herein relates to the field of perfumery. In particular, it provides compositions comprising fragrance materials in a top-heavy construction and at least one substantially non-odorous fragrance modulator for improving or enhancing the fidelity and/or longevity of the fragrance profile. A top-heavy construction generally refers to fragrances including high volatile fragrance materials, or a combination of high volatile and moderate volatile fragrance materials, accounting for at least 30 wt % of the fragrance. The invention also relates to methods of making and using said compositions.
Fragrances can include fragrance components that can be classified, in part, by their volatility. Accordingly these fragrance components may be referred to as a high-, moderate-, or low-volatility fragrance components. Different fragrances may be dominated by any one or more of these component such that the fragrance may be associated with different perceptions by a user. While some high- or moderate-volatility fragrances may be associated with a favorable perception, the volatility of the fragrance may result in a short timeframe in which the fragrance is perceived by a a panel of experts or professional evaluators or individual experts or professional evaluators or in a rapid loss of the initial character of the fragrance (e.g., citrus, aquatic, aromatic, floral, spicy, fresh, or a combination thereof) and becoming dominated by a heavy fragrance character (e.g., woody or musky).
According to various embodiments, a top-heavy composition includes a fragrance component present in an amount of from about 0.04 wt % to about 30 wt %, relative to the total weight of the composition. The fragrance component includes at least one low volatile fragrance material having a vapor pressure less than 0.001 Torr (0.000133 kPa) at 25° C. present in an amount of from about 1 wt % to about 30 w to, relative to the total weight of the fragrance component. The fragrance component further includes at least one moderate volatile fragrance material having a vapor pressure in the range of 0.1 Torr to 0.001 Torr (0.0133 kPa to 0.000133 kPa) at 25° C. present in an amount of from about 25 wt % to about 65 wt %, relative to the total weight of the fragrance component. The fragrance component further includes at least one high volatile fragrance material having a vapor pressure greater than 0.1 Torr (0.0133 kPa) at 25° C. present in an amount of greater than about 30 wt % relative to the total weight of the fragrance component. The composition further includes at least one substantially non-odorous fragrance modulator present in the amount of from about 0.1 wt % to about 20 wt %, relative to the total weight of the composition.
According to various embodiments a top-heavy composition includes a fragrance component present in an amount of from about 0.04 wt % to about 30 wt %, relative to the total weight of the composition. The fragrance component includes at least one low volatile fragrance material having a vapor pressure less than 0.001 Torr (0.000133 kPa) at 25° C. present in an amount of from about 1 wt % to about 30 wt %, relative to the total weight of the fragrance component. The fragrance component further includes at least one moderate volatile fragrance material having a vapor pressure in the range of 0.1 Torr to 0.001 Torr (0.0133 kPa to 0.000133 kPa) at 25° C. present in an amount of from about 30 wt % to about 70 wt %, relative to the total weight of the fragrance component. The fragrance component further includes at least one high volatile fragrance material having a vapor pressure greater than 0.1 Torr (0.0133 kPa) at 25° C. present in an amount of greater than about 30 wt % relative to the total weight of the fragrance component. The composition further includes at least one substantially non-odorous fragrance modulator is chosen from polypropylene glycol-10 methyl glucose ether, ethoxylated methyl glucose ether, and polypropylene glycol-20 methyl glucose ether, present in the amount of from about 0.1 wt % to about 20 wt %, relative to the total weight of the composition.
According to various further embodiments, a top-heavy composition includes a fragrance component present in an amount of from about 0.04 wt % to about 30 wt %, relative to the total weight of the composition. The fragrance component includes at least one low volatile fragrance material having a vapor pressure less than 0.001 Torr (0.000133 kPa) at 25° C. present in an amount of from about 1 wt % to about 30 wt %, relative to the total weight of the fragrance component. The fragrance component further includes at least one moderate volatile fragrance material having a vapor pressure in the range of 0.1 Torr to 0.001 Tor (0.0133 kPa to 0.000133 kPa) at 25° C. present in an amount of from about 25 wt % to about 65 wt %, relative to the total weight of the fragrance component. The fragrance component further includes at least one high volatile fragrance material having a vapor pressure greater than 0.1 Torr (0.0133 kPa) at 25° C. present in an amount of greater than about 30 wt % relative to the total weight of the fragrance component. The composition further includes at least one substantially non-odorous fragrance modulator present in the amount of from about 0.1 wt % to about 20 wt %, relative to the total weight of the composition. At least one of the moderate volatile fragrance material and the high volatile fragrance material is present in the fragrance component for a period of time that is longer than a corresponding fragrance component that is free of the substantially non-odorous fragrance modulator or the equivalent fragrance that has a traditional fragrance construction (e.g., greater than about 30 wt % low volatile material, greater than about 40 wt % low volatile material, greater than about 50 wt % low volatile material, or greater than about 60 wt % low volatile material) or that the high or moderate volatile fragrance material is at a greater level at a given point in time after product application than the same fragrance that is free of the substantially non-odorous fragrance modulator or the equivalent fragrance that has a traditional fragrance construction (e.g., greater than about 30 wt % low volatile material, greater than about 40 wt % low volatile material, greater than about 50 wt % low volatile material, or greater than about 60 wt % low volatile material). In some examples the high volatile fragrance materials may also be present for an extended period of time.
There, are many non-limiting reasons for using the compositions of the instant disclosure. For example, according to various embodiments, the characteristics of the composition can provide rules for objectively classifying fragrance materials according to their volatility using their vapor pressures defined at suitable temperature, instead of their characters. The objective rules operate irrespective of perfumers performing the classification. In particular, the rules classify the fragrance materials into low, moderate or high volatile fragrance materials for formulating into fragrance mixtures. Furthermore, according to some embodiments, the compositions can have improved fidelity to the perceived fragrance profile over time. According to some embodiments, pairing the fragrance components with a selective modulator (e.g., PPG-20 Methyl Glucose Ether) can help to ensure that an initial fragrance impression is significantly consistent from its initial impression to the end. For example, an initial impression of the fragrance can maintain its quality, as perceived by a panel of experts or professional evaluators or individual experts or professional evaluators, for a longer period of time relative to a corresponding fragrance that is free of any one of the modulators, or combinations thereof described herein or relative to the equivalent fragrance that has a traditional fragrance construction (e.g., greater than about 30 wt % low volatile material, greater than about 40 wt % low volatile material, greater than about 50 wt % low volatile material, or greater than about 60 wt % low volatile material)
Beyond extending the initial impression of the fragrance, the strength and longevity of the high volatile fragrances can be improved. For example, according to some embodiments, compositions having improved longevity of the perceived fragrance profile can be present for long periods of time (e.g., greater than 30 mins, 1, 2, 4, 6, or even 8 hours). The improved longevity of the high volatile fragrances may result from the modulator slowing the evaporation of the high and moderate volatile fragrances from the composition.
Additionally, according to some embodiments, the perceived harshness of overdosing of the fragrance material is mitigated or absent, as compared to the same perception in a fragrance in the absence of the modulator.
The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
As used herein, articles such as “a” and “an” when used in a claim, are understood to mean one or more of what is claimed or described.
As used herein, the terms “include”, “includes” and “including” are meant to be non-limiting.
As used herein, the term “body splash” means a body care formulation that is applied to the body. Typically, the body splash is applied to the body after bathing and provides a subtle hint of scent to the body. Body splashes are commonly used by consumers who prefer less strong fragrance compositions. A body splash may comprise an ethanol-free composition according to the present invention which comprises from 0.2-8 wt %, relative to the total weight of the composition, of a fragrance component. The body splash may further comprise alkyl polyglucosides as non-ionic surfactants.
As used herein, the term “body spray” means a formulation comprising fragrance materials intended to be applied to the body to prevent or mask body odor caused by the bacterial breakdown of perspiration on the body (e.g., armpits, feet, and other areas of the body). The body spray may also provide a fragrance expression to the a panel of experts or professional evaluators or individual experts or professional evaluators. Typically, body spray compositions are applied as an aerosol spray in an effective amount on the skin of a consumer.
As used herein, the term “composition” includes a fine fragrance composition intended for application to a body surface, such as for example, skin or hair, e.g., to impart a pleasant odor thereto, or cover a malodour thereof. They are generally in the form of perfume concentrates, perfumes, eau de parfums, eau de toilettes, aftershaves, or colognes. The fine fragrance compositions may be an ethanol-based composition. The term “composition” may also include a cosmetic composition, which comprises a fragrance material for the purposes of delivering a pleasant smell to drive consumer acceptance of the cosmetic composition. The term “composition” may also include body splashes or body sprays. The term “composition” may also include cleaning compositions, such as fabric care composition or home care compositions, including air care compositions (e.g., air fresheners), for use on clothing or other substrates such as hard surfaces (e.g., dishes, floors, countertops). Additional non-limiting examples of “composition” may also include facial or body powder, deodorant, foundation, body/facial oil, mousse, creams (e.g., cold creams), waxes, sunscreens and blocks, bath and shower gels, lip balms, self-tanning compositions, masks and patches.
As used herein, the term “consumer” means both the user of the composition and the observer nearby or around the user.
As used herein, the term “fragrance material” and “fragrance materials” relates to a perfume raw material (“PRM”), or a mixture of perfume raw materials (“PRMs”), that are used to impart an overall pleasant odor or fragrance profile to a composition. “Fragrance materials” can encompass any suitable perfume raw materials for fragrance uses, including materials such as, for example, alcohols, aldehydes, ketones, esters, ethers, acetates, nitriles, terpene hydrocarbons, nitrogenous or sulfurous heterocyclic compounds and essential oils. However, naturally occurring plant and animal oils and exudates comprising complex mixtures of various chemical components are also known for use as “fragrance materials”. The individual perfume raw materials which comprise a known natural oil can be found by reference to Journals commonly used by those skilled in the art such as “Perfume and Flavourist” or “Journal of Essential Oil Research”, or listed in reference texts such as the book by S. Arctander, Perfume and Flavor Chemicals, 1969, Montclair, N.J., USA and more recently re-published by Allured Publishing Corporation Illinois (1994). Additionally, some perfume raw materials are supplied by the fragrance houses (Firmenich, International Flavors & Fragrances, Givaudan, Symrise) as mixtures in the form of proprietary specialty accords. Non-limiting examples of the fragrance materials useful herein include pro-fragrances such as acetal pro-fragrances, ketal pro-fragrances, ester pro-fragrances, hydrolyzable inorganic-organic pro-fragrances, and mixtures thereof. The fragrance materials may be released from the pro-fragrances in a number of ways. For example, the fragrance may be released as a result of simple hydrolysis, or by a shift in an equilibrium reaction, or by a pH-change, or by enzymatic release.
As used herein, the term “fragrance profile” means the description of how the fragrance is perceived by the human nose at any moment in time. The fragrance profile may change over time. It is a result of the combination of the low, moderate and high volatile fragrance materials, if present, of a fragrance. A fragrance profile is composed of 2 characteristics: ‘intensity’ and ‘character’. The ‘intensity’ relates to the perceived strength whilst ‘character’ refers to the odor impression or quality of the perfume, e.g., fruity, floral, woody, etc.
As used herein, the terms “modulator”, and “fragrance modulator” are used interchangeably to designate an agent having the capacity to affect the fragrance profile, such as for example, by impacting the fragrance materials' evaporation rate. The modulator may mediate its effect by lowering the vapor pressure of the fragrance materials and increasing their adherence to the substrate (skin and/or hair) thus ensuring a longer-lasting impression of the fragrance. By incorporating the modulator, it is desired that the fragrance profile, preferably the fragrance components composition attributable to the high and moderate volatile fragrance materials, alone or individually, of the composition can be perceived by a a panel of experts or professional evaluators or individual experts or professional evaluators, over a longer period of time, or the perceived harshness of overdosing of the fragrance material is mitigated or absent, as compared to the same perception in the absence of the modulator. As used herein “overdose” can include overdosing a moderate volatile component or high volatile component in aggregate (e.g., greater than 30 wt % of the fragrance component). The term “overdose” can further include overdosing an individual component of the moderate volatile component or the high volatile component (e.g., if the high volatile component includes three oils at least one of the oils may account for a greater wt % of the high volatile component than would be present in a traditional fragrance or a fragrance that is free of the modulators described herein). Suitable examples of the modulator are provided herein below. However, as discovered by the inventors, simply adding modulators to a traditionally constructed fragrance composition (e.g., classical fragrance pyramid construction) will not ensure an improved or enhanced fidelity and/or longevity of the fragrance profile over time.
As used herein, the term “substantially non-odorous” means an agent that does not impart an odor of its own when added into a composition of the present invention. For example, a “substantially non-odorous fragrance modulator” does not impart a new odor that alters the character of the fragrance profile of the composition to which it is added. The term “substantially non-odorous” also encompasses an agent that may impart a minimal or slight odor of its own when added into a composition of the present invention. However, the odor imparted by the “substantially non-odorous fragrance modulator” is generally undetectable or tends to not substantively alter the character of the fragrance profile of the composition to which it is added initially or preferably over time. Furthermore, the term “substantially non-odorous” also includes materials that are perceivable only by a minority of people or those materials deemed “anosmic” to the majority of people. Furthermore, the term “substantially non-odorous” also includes materials that may, from particular suppliers, contain an odor due to impurities, such as when the materials contain the impurities at not more than about 5 wt %, preferably not more than 1 wt %, often even not more than 1 part per million (ppm). These impurities maybe removed by purification techniques known in the art as required to make them suitable for use in fragrance compositions of the present invention.
As used herein, the term “vapor pressure” means the partial pressure in air at a defined temperature (e.g., 25° C.) and standard atmospheric pressure (760 mmHg) for a given chemical species. It defines a chemical species' desire to be in the gas phase rather than the liquid or solid state. The higher the vapor pressure the greater the proportion of the material that will, at equilibrium, be found in a closed headspace. It is also related to the rate of evaporation of a fragrance material which is defined in an open environment where material is leaving the system. The vapor pressure is determined according to the reference program Advanced Chemistry Development (ACD/Labs) Software Version 14.02, or preferably the latest version update).
It is understood that the test methods that are disclosed in the Test Methods Section of the present application must be used to determine the respective values of the parameters of Applicants' inventions as described and claimed herein.
In all embodiments of the present invention, all percentages are by weight of the total composition, as evident by the context, unless specifically stated otherwise. All ratios are weight ratios, unless specifically stated otherwise, and all measurements are made at 25° C., unless otherwise designated.
The inventive subject matter herein is directed towards top-heavy fragrance compositions or mixtures having improved fragrance profile fidelity and longevity Disclosed fragrance compositions can include at least a fragrance component and modulator. The fragrance component can include a wide variety of fragrance materials. The fragrance materials can be grouped in terms of their volatility. Generally, the materials can be grouped as low volatile fragrance materials, moderate volatile fragrance materials, and high volatile fragrance materials. Each group of materials can be associated with various perceptions by a a panel of experts or professional evaluators or individual experts or professional evaluators. While not so limited, a high volatile fragrance may be associated with a citrus character; a moderate volatile fragrance may be associated with a spicy character; and a low volatile fragrance may be associated with a woody character. Each group of fragrance materials can include synthetic materials or natural materials. The volatility of the fragrance materials can be in reference to an individual fragrance material. Alternatively, in cases where a combination of materials produce a fragrance, for example a natural oil, the volatility may be in reference to that aggregation.
In some examples, this disclosure shows that longer lasting fragrance profiles or at least initial fragrance profiles, may be enhanced through the presence of certain modulators.
With respect to the composition, the fragrance component can be present in an amount of from about 0.04 wt % to 30 wt %, 1 wt % to about 30 wt %, about 5 wt % to about 30 wt %, or less than, equal to, or greater than about 0.04 wt %, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12, 12.5, 13, 13.5, 14, 14.5, 15, 15.5, 16, 16.5, 17, 17.5, 18, 18.5, 19, 19.5, 20, 20.5, 21, 21.5, 22, 22.5, 23, 23.5, 24, 24.5, 25, 25.5, 26, 26.5, 27, 27.5, 28, 28.5, 29, 29.5, or about 30 wt % relative to the composition.
Additionally with respect to the composition, the modulator can be present in an amount of from about 0.1 wt % to about 20 wt %, about 0.5 wt % to about 20 wt %, or less than, equal to, or greater than about 0.1 wt %, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12, 12.5, 13, 13.5, 14, 14.5, 15, 15.5, 16, 16.5, 17, 17.5, 18, 18.5, 19, 19.5, or about 20 wt % relative to the composition.
As described herein, the “fragrance materials” have been classified as low, moderate or high volatile fragrance materials according to their volatility by their vapor pressure. This method of classifying fragrance materials by their vapor pressure avoids the problem of different classifications for the same fragrance material according to the traditional approach that relies on their subjective characteristic character. In the case that the fragrance materials are a natural oil, extract or absolute, which comprises a mixture of several compounds, the vapor pressure of the complete oil should be treated a mixture of the individual perfume raw material components using the reference program cited above. The individual components and their level, in any given natural oil or extract, can be determined by direct injection of the oil into a GC-MS column for analysis as known by one skilled in the art. In the scenario that the fragrance materials are a proprietary specialty accord, so called ‘bases’, the vapor pressure, using the reference program cited above, should preferably be obtained from the supplier. However, it is understood by one skilled in the art that they can physically analyze the composition of a full fragrance oil available commercially to identity the fragrance raw materials and their levels using standard GC-MS techniques. This would be irrespective of whether they had been added to the fragrance oil as individual chemicals, as components of naturals or from proprietary bases. Although proprietary bases and naturals are included in our examples, when analyzing a commercially available fragrance via GC-MS one could simply identify the components of the base or natural oil as part of the overall fragrance mixture and their levels, without being able to identify which proprietary base or natural oil the fragrance had come from.
(i) Low Volatile Fragrance Materials
The fragrance component comprises at least one low volatile fragrance material. Individual low volatile fragrance materials or aggregate low volatile fragrance materials are those having a vapor pressure less than 0.001 Torr (0.000133 kPa) at 25° C. According to some examples, the composition can include at least 3 low volatile fragrance materials, or at least 4 low volatile fragrance materials, or at least 5 low volatile fragrance materials, or at least 7 low volatile fragrance materials. The amount of the low fragrance material present in the fragrance component can vary depending on the specific application. For example, the low volatile fragrance material can be present in an amount ranging from about 0.1 wt % to about 30 wt % of the fragrance component, about 1 wt % to about 30 wt %, about 5 wt % to about 30 wt, or less than, equal to, or greater than about 0.1 wt, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12, 12.5, 13, 13.5, 14, 14.5, 15, 15.5, 16, 16.5, 17, 17.5, 18, 18.5, 19, 19.5, 20, 20.5, 21, 21.5, 22, 22.5, 23, 23.5, 24, 24.5, 25, 25.5, 26, 26.25, 27, 27.5, 28, 28.5, 29, 29.5, or about 30 wt %.

Exemplary high volatile fragrance materials selected from the group of Tables 3A or 3B are preferred. However, it is understood by one skilled in the art that other high volatile fragrance materials, not recited in Tables 3A or 3B, would also fall within the scope of the present invention, so long as they have a vapor pressure of greater than 0.1 Torr (0.0133 kPa) at 25° C.
(iv) Fragrance Modulators
The composition further comprises at least one substantially non-odorous fragrance modulator as described herein below. Suitable examples of the substantially non-odorous fragrance modulators are provided in Table 4 below.
The substantially non-odorous fragrance modulator can be present in an amount of from about 0.1 wt % to about 20 wt % relative to the total weight of the composition of the composition, about 0.5 wt % to about 18 wt %, about 2.5 wt % to about 15 wt %, or less than, equal to, or greater than about 0.1 wt %, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12, 12.5, 13, 13.5, 14, 14.5, 15, 15.5, 16, 16.5, 17, 17.5, 18, 18.5, 19, 19.5, 20 wt %. If there are more than one substantially non-odorous fragrance modulators, then the ranges provided hereinabove cover the total of all of the substantially non-odorous fragrance modulators.
The substantially non-odorous fragrance modulator can be a liquid at temperatures lower than 100° C., such as at ambient temperature. The substantially non-odorous fragrance modulators may be fully miscible with the fragrance materials to form a single phase liquid. However, if the fragrance materials are not entirely miscible, or are immiscible, then co-solvents (e.g., dipropylene glycol (DPG), triethyl citrate, or others well known to those skilled in the art) can be added to aid in the solubility of the fragrance materials.
According to various examples, the effect of the substantially non-odorous fragrance modulator on the fragrance profile, particularly the characters of the fragrance profile which is attributable to the high and moderate volatile fragrance materials, can be improved. By “improved” it is meant that the fragrance profile of the composition, particular the components contributed by at least one of the high and moderate volatile fragrance materials, can be perceived by the a panel of experts or professional evaluators or individual experts or professional evaluators at later time points such as, for example, 15 mins, 30 mins, 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 10 hours, and possibly all the way up to 24 hrs after application as compared to controls, e.g., lacking any of the disclosed non-odorous fragrance modulators such as PPG-20 Methyl Glucose Etheror an equivalent traditional fragrance construction.
Alternatively, by “improved” it can mean that the perception, by the a panel of experts or professional evaluators or individual experts or professional evaluators, of the fidelity of the fragrance profile contributed by the high and moderate volatile fragrance materials is markedly increased or enhanced as compared to the controls. “Increased” or “enhanced” means that the a panel of experts or professional evaluators or individual experts or professional evaluators perceives the fragrance profile, preferably the characters attributable to the high and/or moderate volatile fragrance materials, of a composition as not changing from its initial impression or the changes are minimal from when the composition was first applied to when it dissipates. In other words, the fidelity of the perceived fragrance profile of the composition is maintained over time. In contrast the composition lacking any of the disclosed nom-odorous fragrance modulators or an equivalent traditional fragrance construction will undergo a rapid loss of the characters attributable to the high and/or moderate volatile fragrance materials.
Such a solution as presented herein provides enhanced or improved fidelity and/or longevity of the fragrance profile, particularly amongst those composition formulated from volatile fragrance materials having moderate to high vapor pressure ranges (greater than or equal to 0.001 Torr (0.000133 kPa) at 25° C.), without having to rely on the presence or significant amounts of the low volatile fragrance materials, which has a tendency to overpower and alter the overall fragrance profile, particularly over time. As a result, the present disclosure provides the perfumer options to formulate compositions having new fragrance profiles not possible before.
Additionally, according to some embodiments, the perceived harshness of overdosing of the fragrance material is mitigated or absent, as compared to the same perception in a fragrance in the absence of the modulator.
Suitable examples of non-odorous modulators can include methyl glucoside polyol, ethyl glucoside polyol, propyl glucoside polyol, or mixtures thereof. Further examples can include from polypropylene glycol-10 methyl glucose ether, ethoxylated methyl glucose ether, polypropylene glycol-20 methyl glucose ether, caprylyl/capryl glucoside, undecyl glucoside, and mixtures thereof. In some examples, the composition can be substantially free of isocetyl alcohol, diisobutyl adipate, diisoamyl adipate, polypropylene glycol-3 myristyl ether, and neopentyl glycol diethyl hexanoate, neopentyl glycol diisononanoate, cetearyl ethyl hexanoate, and their mixtures, or a mixture thereof, although the composition can optionally include these.

Further examples of non-odorous fragrance modulator is selected from the group of materials disclosed in Table 4(b).
The compounds, as described above in Tables 4(a) and 4(b), act as a substantially non-odorous fragrance modulator of the perceived fidelity and/or longevity of the fragrance profile of the composition of the present invention. For example, the substantially non-odorous fragrance modulators, with a fragrance component having a top-heavy fragrance construction, act to prolong the duration during which the fragrance profile, preferably the characters attributable from the high and moderate volatile fragrance materials, can be perceived as compared to a control composition in the absence of the modulators or having the traditional fragrance pyramid three-tiered structure. As another example, the substantially non-odorous fragrance modulators, with a fragrance component having a top-heavy fragrance construction, can improve the fidelity of the fragrance profile, preferably the characters attributable from the high volatile fragrance materials, such that it remains significantly the same from initial impression to the end as compared to a control composition in the absence of the modulators or having the traditional fragrance pyramid three-tiered structure. While not wishing to be bound by theory, it is believed that the substantially non-odorous fragrance modulators associate to the fragrance materials and retard evaporation. Additionally, without wishing to be bound by theory, it is believed that the substantially non-odorous fragrance modulators associate to the high and moderate-volatility fragrance materials to allow for high wt % while mitigating or eliminating a perceived harshness of the composition by the user.
The composition according to the present invention, can include a volatile solvent present in the amount of from about 20 wt % to about 99 wt % relative to the total weight of the composition, about 30 wt/o to about 80 wt %, about 55 wt % to about 75 wt %, or less than, equal to, or greater than about 20 wt %, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, or about 99 wt %, and wherein the solvent is a branch or unbranched C1 to C10 alkyl, alkenyl or alkynyl group having at least one alcohol moiety, preferably ethanol, or isopropanol, or other alcohols (e.g., methanol, propanol, isopropanol, butanol, and mixtures thereof) commonly found in commercial fine fragrance products.
Accordingly, ethanol may be present in any of the compositions of the present invention, and more specifically, it will form from about 5 wt % to about 95 wt %, or even from about 10 wt % to about 80 wt %, 25 wt to about 75 wt % of the composition, or combinations thereof, relative to the total weight of the composition. Alternatively, ethanol may be present in an amount of from about 10 wt or 25 wt % to about 75 wt % or 80 wt %, relative to the total weight of the composition. The ethanol useful in the present invention may be any acceptable quality of ethanol, compatible and safe for the specific intended use of the composition such as, for example, topical applications of fine fragrance or cosmetic compositions.
In some examples (e.g., those including a volatile solvent), water may be present in any of the compositions of the present invention, and more specifically, it may not exceed about 95 wt % relative to the total weight of the composition, about 90 wt % or less, about 85 wt % or less, about 80 wt % or less, about 75 wt % or less, about 70 wt % or less, about 65 wt % or less, about 60 wt % or less, about 55 wt % or less, about 50 wt % or less, about 45 wt % or less, about 40 wt % or less, about 35 wt % or less, about 30 wt % or less, about 20 wt % or less, about 10 wt %, or less than, equal to, or greater than about 95 wt %, 90, 85, 80, 75, 70, 65, 60, 55, 50, 45, 40, 30, 35, 30, 25, 20, 15, 10, or 5 wt %. Alternatively, water may be present in an amount of from about 5 wt % or about 95 wt % When the composition is a cosmetic composition the level of water should not be so high that the product becomes cloudy thus negatively impacting the product aesthetics. It is understood that the amount of water present in the composition may be from the water present in the volatile solvent (e.g., ethanol) used in the composition, as the case may be.
The composition may comprise a non-volatile solvent or a mixture of non-volatile solvents. Non-limiting examples of non-volatile solvents include benzyl benzoate, diethyl phthalate, isopropyl myristate, propylene glycol, dipropylene glycol, triethyl citrate, and mixtures thereof. These solvents often are introduced to the product via the perfume oil as many perfume raw materials may be purchased as a dilution in one of these solvents. Where non-volatile solvents are present, introduced either with the perfume materials or separately, then for the purposes of calculating the proportion of fragrance component having a vapor pressure of less than 0.001 Torr (0.000133 kPa) at 25° C. the total fragrance components does not include non-volatile solvents. Where non-volatile solvents are present, introduced either with the perfume materials or separately, then for the purposes of calculating the total level of fragrance component this does not include non-volatile solvents. In addition, if present with cyclic oligosacchrides, the non-volatile solvent may be included at a weight ratio of the non-volatile solvent to the cyclic oligosaccharide of less than 1:1, less than 1:2, less than 1:10, or less than 1:100.
In other examples, compositions of the present invention can include an entrapment material at a level such that the weight ratio of the entrapment material to the fragrance materials is in the range of from about 1:20 to about 20:1. in some examples, the composition may comprise an entrapment material present in the amount of from about 0.001 wt % to about 40 wt %, from about 0.1 wt % to about 25 wt %, from about 0.3 wt % to about 20 wt %, from about 0.5 wt % to about 10 wt %, or from about 0.75 wt % to about 5 wt %, relative to the total weight of the composition. The compositions disclosed herein may include from 0.001 wt % to 40%, from 0.1 wt % to 25 wt %, from 0.3 wt % to 20 wt %, from 0.5 wt % to 10 wt % or from 0.75 wt % to 5 wt %, relative to the total weight of the composition, of a cyclic oligosaccharide.

The cyclic oligosaccharides of the compositions used for the present invention can be soluble in water, ethanol, or both water and ethanol. As used herein “soluble” means at least about 0.1 g of solute dissolves in 100 mL of solvent, at 25° C. and 1 standard atmospheric pressure (760 mmHg). The cyclic oligosaccharides for use herein have a solubility of at least about 1 g/100 mL, at 25° C. and 1 atm of pressure. In some examples, cyclic oligosaccharides are only present at levels up to their solubility limits in a given composition at room temperature. A person skilled in the art will recognize that the levels of cyclic oligosaccharides used in the present invention will also be dependent on the components of the composition and their levels, for example the solvents used or the exact fragrance oils, or combination of fragrance oils, present in the composition. Therefore, although the limits stated for the entrapment material are preferred, they are not exhaustive.

In another aspect, the present invention is also directed to a method of producing a consumer product comprising bringing into contact or mixing into the product an organoleptically active quantity of a composition of the present invention.
The following assays set forth must be used in order that the invention described and claimed herein may be more fully understood.
In order to determine the vapor pressure for the fragrance materials, go to the website https://sc finder.cas.org/scifinder/view/scifinder/scifinder/Explore.jsf and follow these steps to acquire the vapor pressure.
1. Input the CAS registry number for the particular fragrance material.
2. Select the vapor pressure from the search results.
3. Record the vapor pressure (given in Torr at 25° C.).
SciFinder uses Advanced Chemistry Development (ACD/Labs) Software Version 11.02. (© 1994-2018). If the CAS number for the particular fragrance material is unknown or does not exist, you can utilize the ACD/Labs reference program to directly determine the vapor pressure. Vapor Pressure is expressed in 1 Torr, which is equal to 0.133 kilopascal (kPa).
In order to show the effect of the substantially non-odorous fragrance modulators and fragrance component of the present invention on the perception of fragrance profile in a composition of the present invention, test compositions are made, as described in the Example section, and given to expert panelists to evaluate.
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 of fragrance evaluation in the industry. Typically, around 4-6 expert panelists 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 5 herein below.
The panelists are asked to assess the fragrance character in one of 2 ways: i) 10 (i) a score on a scale of 0 to 3 for the dominance of particular characters that are relevant to that particular fragrance, e.g.: harsh, green, watery, floral, rose, muguet, fruity, apple, berry, citrus, creamy, woody, balsamic, amber, musk just to name a few, according to the odour grading scale set out in Table 6(i) herein below;
ii) (ii) a score on a scale of 1 to 5 for changes in the perceived fragrance profile change for the test compositions versus the controls according to the odour grading scale set out in Table 6(ii) herein below.
The results of the panelists are averaged and if sufficient panelists are available, typically around 10, then the data can be analyzed using Analysis of Variance methods. The model treats the subject as a random effect and looks at the impact of product, time and the interaction between product and time. From the analysis, the least square means for the product and time interaction are obtained. These means (as well as their confidence intervals) are then plotted to enable comparisons between products at each time point. It should be noted that the confidence levels plotted are intended as a guide, and not as a statistical comparison, as they do not take into account that multiple testing has been performed. As well as a graphical assessment, statistical comparisons between the two products at each of the time points are performed with a Sidak correction for multiple comparisons. The p-values for the product differences are obtained, with p-values <0.05 indicating a statistical difference between the two products at 5% significance (or 95% confidence). Typically for assessments by expert panelists of evaluators and perfumers there are 4-6 participants. In these cases a full statistical analysis is not possible and typically we observe that an difference in means of 0.75 on the scales used is considered to be meaningful, i.e.: 3 out of 4 experts gave the products grades with a difference of 1.
In order to show the effect of the substantially non-odorous fragrance modulators and fragrance component on the perception of fragrance profile in a composition of the present invention, test compositions are made, as described in the Example section, and given to panelists to evaluate and describe.
At the testing facility, 20 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. 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. The experiments are run in duplicate on 2 different days and the data combined. In the subsequent analysis, the data for strength and character comparisons are drawn from the independent assessments carried out at a given time point.
Panelists are individuals who are specifically trained to evaluate fragrances according to the scale below using odour standards for calibration. Calibration standards are selected from perfume materials that represent specific families, for example, without being exhaustive, for the woody family panelists are calibrated with cedarwood, vetivert oil, patchouli oil, iso-E super, Norlimbanol and sandalwood or for harshness, for example, without being exhaustive, panelists are calibrated with pyrazines, Vertocitral, Aldehyde phenylacetic, Cedar Atlas and Cuminic aldehyde. Around 10-15 panelists are used to evaluate a given product and its control. Panelists assess the samples according to 2 scales:
(a) Fragrance Intensity:
The panelists give a score on a unlabeled continuous scale where 0 is no perceptible odour and 10 is very strong odour.
(b) Fragrance Character:
The panelists assess the fragrance character according to a number of pre-defined attributes e.g.: citrus, green, aromatic, floral, fruity, spicy, musk, woody, fresh, harsh just to name a few, scoring each one on unlabeled continuous scale where 0 is no perceptible odor and 10 is very strong odor.
The results of the panelists are analyzed using three-way analysis of variance (replicate/sample/panellist) with interaction followed by Duncan post-hoc multiple comparison test. The p-values for the product differences are obtained, with p-values <0.05 indicating a statistical difference between products at 5% significance (or 95% confidence) and with p-values <0.10 indicating a statistical difference between products at 10% significance (or 90% confidence). The data is represented graphically in bar or line charts showing the average for each attribute at a given time point with 95% confidence intervals as error bars.

Using the analytical evaporation Test Method 3, it is possible to measure the amount of each component of a perfume mixture that remains as the fragrance mixture evaporates. Test compositions in Tables 13, 14, 15 &15 (a) are introduced in the aluminum pan at the set temperature for pre-determined periods of time in accordance with the protocol described in Test Method 3. The amount of each individual high volatility fragrance materials remaining is aggregated and the total high volatility fragrance materials remaining is plotted over time.
The percentage of high volatility fragrance materials remaining in a traditionally constructed fragrance oil example 3A in the absence of a modulator decreases very quickly to 21% of starting level in 30 mins, 7% in 60 mins and close to zero in 120 mins. For a fragrance constructed with the high level of high volatility materials in example 3 in combination with one of the modulators, the reduction is much slower demonstrating the delayed evaporation of the high volatility perfume materials. For example for GLUCAM™ P-20 it is 40% and for Ceraphyl® A 69% after 30 mins and 24% and 39% respectively after 60 mins. The reduction in evaporation is achieved with a variety of modulators.
The percentage of high volatility fragrance materials remaining in the traditionally constructed fragrance oil example 2A in the absence of a modulator decreases very quickly to 16% of the starting level in 60 mins and close to zero in 120 mins. For the fragrance constructed with a high level of high volatility materials oil example 2 in combination with one of the modulators, the reduction is much slower demonstrating the delayed evaporation of the high volatility perfume materials. For example, for Ceraphyl® ICA 53% after 60 mins and 37% after 120 mins whilst for Schercemol™ NGDO it is 47% after 60 mins and 27% 5 after 120 mins. The reduction in evaporation is achieved with a variety of modulators.
