The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
Reference will now be made in detail to certain embodiments of the disclosed subject matter. While the disclosed subject matter will be described in conjunction with the enumerated claims, it will be understood that the exemplified subject matter is not intended to limit the claims to the disclosed subject matter.
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 consumers. 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 less harsh impression of the overdosed fragrance.
By incorporating the modulator, it is desired that the fragrance profile, preferably the fragrance components composition attributable to the moderate and low volatile fragrance materials, alone or individually, of the composition can be perceived by a panel of experts or professional evaluators or individual experts or professional evaluators, without the perceived harshness of overdosing (e.g., greater than about 30 wt % of the composition) of the low and moderate fragrance materials is mitigated or absent, as compared to the same perception in the absence of the modulator. Suitable examples of the modulator are provided herein below. However, as discovered by the inventors, simply adding a primer containing modulators to a traditionally constructed fragrance composition (e.g., classical fragrance pyramid construction without overdose) that is commercially available in the market will enhance the perception of medium and high volatile materials and preserve them over time. It is necessary that fragrance construction has a predominantly green, fruity, floral and citrus character to achieve best results. Nonetheless desired character change is achieved with any commercial fragrance as described by experts or professional evaluators or individual experts or professional evaluators experience.
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.
Throughout this document, values expressed in a range format should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. For example, a range of “about 0.1% to about 5%” or “about 0.1% to 5%” should be interpreted to include not just about 0.1% to about 5%, but also the individual values (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%) within the indicated range. The statement “about X to Y” has the same meaning as “about X to about Y,” unless indicated otherwise. Likewise, the statement “about X, Y, or about Z” has the same meaning as “about X, about Y, or about Z,” unless indicated otherwise.
In this document, the terms “a,” “an,” or “the” are used to include one or more than one unless the context clearly dictates otherwise. The term “or” is used to refer to a nonexclusive “or” unless otherwise indicated. The statement “at least one of A and B” has the same meaning as “A, B, or A and B.” In addition, it is to be understood that the phraseology or terminology employed herein, and not otherwise defined, is for the purpose of description only and not of limitation. Any use of section headings is intended to aid reading of the document and is not to be interpreted as limiting; information that is relevant to a section heading may occur within or outside of that particular section.
In the methods described herein, the acts can be carried out in any order without departing from the principles of the disclosure, except when a temporal or operational sequence is explicitly recited. Furthermore, specified acts can be carried out concurrently unless explicit claim language recites that they be carried out separately. For example, a claimed act of doing X and a claimed act of doing Y can be conducted simultaneously within a single operation, and the resulting process will fall within the literal scope of the claimed process.
The term “about” as used herein can allow for a degree of variability in a value or range, for example, within 10%, within 5%, or within 1% of a stated value or of a stated limit of a range, and includes the exact stated value or range.
The term “substantially” as used herein refers to a majority of, or mostly, as in at least about 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, 99.99%, or at least about 99.999% or more, or 100%.

The composition can then be added to an existing fragrance composition.
Fragrance Modulators
The coating composition 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 1 below.
The substantially non-odorous fragrance modulator can be present in an amount of from about 0.1 wt % to about 50 wt % relative to the total weight of the coating composition or the composition, about 0.5 wt % to about 40 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, 20.5, 21, 21.5, 22, 22.5, 23, 23.5, 24, 24.5, 25, 25.5, 26, 26.5, 27.5, 28, 28.5, 29, 29.5, 30, 30.5, 31, 31.5, 32, 32.5, 33, 33.5, 34, 34.5, 35, 35.5, 36, 36.5, 37, 37.5, 38, 38.5, 39, 39.5, 40, 40.5, 41, 41.5, 42, 42.5, 43, 43.5, 44, 44.5, 45, 45.5, 46, 46.5, 47, 47.5, 48, 48.5, 49, 49.5, 50 wt %. If there are more than one substantially non-odorous fragrance modulators, then the ranges provided herein above cover the total of all of the substantially non-odorous fragrance modulators in the composition. According to various embodiments, the modulator can be present exclusively in a primer as opposed to being in a fragrance composition.
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 a fragrance material(s) 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.
The coating can be used in conjunction with a fragrance composition. For example, the fragrance composition can be applied to the coating and the substantially non-odorous fragrance modulator can permeate to the fragrance component. The coating can be left to dry or be a liquid when a fragrance component is brought into contact with the coating. 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 medium and high volatile fragrance materials, can be improved. By “improved” it is meant that the fragrance profile of the composition, particularly the components contributed by at least one of the medium and high volatile fragrance materials, can be perceived by the panel of experts or professional evaluators or individual experts or professional evaluators at later time points such as, for example, 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 Glucam.
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 1(b).
As described further herein. The compounds, as described above in Tables 1(a) and 1(b), act as a substantially non-odorous fragrance modulator of fragrance materials of the present invention. Without wishing to be bound by theory, it is believed that the substantially non-odorous fragrance modulators associate to fragrance materials to allow for high or overdosed wt % values of the fragrance materials (e.g., greater than 30 wt %) in a composition to which the coating contacts will allow the overdosed fragrance materials to drive the perceived character of the fragrance, while mitigating or eliminating a perceived harshness of the composition by the user. The non-odorous fragrance modulators can also be used in materials that do not include overdosed fragrance materials.
The composition including the substantially non-odorous fragrance modulator according to the present invention, can include a volatile solvent, a non-volatile solvent, or a mixture thereof. The solvent can be organic or aqueous. Where present, the volatile solvent can be present in the amount of from about 20 wt % to about 99 wt % relative to the total weight of the composition, about 30 wt % 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, akenyl 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.
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. 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 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. In some examples, the coating composition contains only substantially non-odorous components.
The coating compositions described herein can be used in conjunction with a fragrance composition. The fragrance composition can include one or more fragrance components that can be characterized by their respective volatilities. For example, fragrance components can be low volatility, moderate volatility, or high volatility fragrance components. According to various embodiments, a fragrance composition can be overdosed with one or more of the fragrance components such that fragrance composition can be considered to be a bottom-heavy fragrance, a middle-heavy fragrance, a top-heavy fragrance composition, or a composition where fragrance components are evenly distributed.
Each group of materials can be associated with various perceptions by 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 the volatility may be in reference to that aggregation.
With respect to a fragrance 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. Additional components in the fragrance composition can include a carrier such as the organic, inorganic, or aqueous carriers described herein with respect to the coating composition.
Additionally, according to various embodiments, it is possible for the fragrance composition to include any one or more of the modulators described herein with respect to the coating composition. Where present in the coating 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 coating 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.
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 volatile fragrance material present in the fragrance component can vary depending on the specific application. In some embodiments, the low volatile fragrance component can be in a range of from about 0 wt % to about 100 wt % of the fragrance component, about 10 wt % to about 90 wt %, about 20 wt % to about 80 wt %, about 30 wt % to about 70 wt %, or about 40 wt % to about 60 wt %.

Fragrance ingredient was weighed, and added progressively to 5 gr of target solution. At each step, 0.050 gr of fragrance raw material was added, and shaken vigorously during 2 minutes to form a clear aqueous solution at room temperature. When insoluble, the mixture was allowed to sit for 8 hours to solubilize. The mixture was considered soluble when not appearing cloudy and no suspended oil or particles were visible after 8 hours.
Table 5 shows the effect of coating composition applied as a primer on two commercial products with a unique fragrance composition. These fragrances were constructed with a similar content of high- and low-volatility fragrance ingredients, and a lower content of mid-volatility fragrance ingredients as per the definitions in this patent. As it can be seen from the results, over time the difference in fragrance character becomes more evident. Surprisingly, the use of the primer composition enhances aromatic, citrus and woody notes, but reduced green notes in contrast to what is observed for other constructions.
Classical perfume contain a high % of ethanol to solubilize perfume raw materials. Surprisingly, by the addition of a high amount of glucam, compensated by a removal of water, some raw materials like Ambroxan and Cedrol Crystals can be further solubilized as shown in Table 6. In the first case, solubility increased 6.49% whereas in the second one a 57.8%. Furthermore, natural raw materials like Coffee Santos SFE could be solubilized into glucam-containing composition. This gives the opportunity to create new olfactive spaces otherwise impossible.
