Patent Application
20160362631
The present invention concerns substantially non-odorous fragrance fixatives and compositions comprising said substantially non-odorous fragrance fixatives to extend the fragrance profile, preferably the fragrance intensity and/or fragrance character, of the fragrance materials over time.
Fragrances in some products, particularly (but not exclusively) ethanol-based ones, tend to lose their fragrance profile (i.e., character and intensity) rapidly after application. Various materials have been used to make the fragrance profile last longer. These are known as fragrance fixatives. Some substantially non-odorous examples include: (i) capsules or complexes based on dextrines, melamines or obtained by coacervation of anionic and cationic polymers, (ii) film-forming polymers, or (iii) perfume base notes such as musks. The drawbacks of capsules or complexes are that they are difficult to formulate into a fragrance composition and/or the release is little controlled but depends on variable factors like moisture or sebum amount or sweat intensity. The issue with film-forming polymers is that they produce very noticeable and undesirable films (both visual and tactile). The disadvantage of perfume base notes is that they can negatively impact the fragrance character of the compositions to which they are added.
Thus, there is a need for new fragrance fixatives to extend the fragrance profile, preferably the intensity or character, of a fragrance material to maintain its intensity over time and particularly in retaining the initial character and intensity of the characters. It is also desirable that the fragrance fixatives should not adversely affect the aromatic and/or aesthetic character of the products to which they are added.
In one aspect, the present invention provides a substantially non-odorous fragrance fixative comprising at least one material selected from the group consisting of the materials in Table 1, as provided herein below.
In another aspect, the present invention is directed to a composition comprising 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, and at least one substantially non-odorous fragrance fixative, as described herein below, present in an amount of from about 0.1 wt % to about 20 wt %, relative to the total weight of the composition.
In yet another aspect, the present invention is further directed to a method of modifying or enhancing the odour properties of a surface with a composition of the present invention, by contacting or treating the surface with the composition.
In yet another aspect, the present invention is further directed to a composition comprising fragrance materials and a substantially non-odorous fragrance fixative according to Table 1 for extending the fragrance profile of the fragrance materials vs. a control composition absent of the substantially non-odorous fragrance fixative.
These and other features of the present invention will become apparent to one skilled in the art upon review of the following detailed description when taken in conjunction with the appended claims.
While the specification concludes with claims particularly pointing out and distinctly claiming the invention, it is believed that the invention will be better understood from the following description of the accompanying figures wherein:
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 surface, such as for example, body surface like skin or hair, i.e., to impart a pleasant odour thereto, or cover a malodour thereof. They are generally in the form of perfume concentrates, perfumes, parfums, 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, foundation, deodorant, 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 terms “fragrance” and “perfume” are used interchangeably to designate the component in the composition that is formed of fragrance materials, i.e., ingredients capable of imparting or modifying the odour of skin or hair or other substrate.
As used herein, the term “fragrance material” and “fragrance materials” relates to a perfume raw material, or a mixture of perfume raw materials, that are used to impart an overall pleasant odour 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 know 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 speciality 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 volatile fragrance materials and the 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 odour impression or quality of the perfume, i.e., fruity, floral, woody, etc.
As used herein, the terms “fixative” and “fragrance fixative” 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 fixative 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. Suitable examples of the fixative are provided herein below, particularly in Table 1.
As used herein, the term “substantially non-odorous” means an agent that does not impart an odour of its own when added into a composition of the present invention. For example, a “substantially non-odorous fragrance fixative” does not impart a new odour 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 odour of its own when added into a composition of the present invention. However, the odour imparted by the “substantially non-odorous fragrance fixative” 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 odour 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 (e.g., 760 mmHg or 101.325 kPa) 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.
Substantially Non-Odorous Fragrance Fixatives The inventors have discovered new agents that can be used as substantially non-odorous fragrance fixatives, as described herein below, to enhance or improve the fragrance profile, preferably the intensity or character, of the fragrance material. Preferable examples of the substantially non-odorous fragrance fixatives are provided in Table 1 below.
Preferably, the substantially non-odorous fragrance fixative is present in an amount of from about 0.1 wt % to about 20 wt %, preferably from about 0.5 wt % to about 18 wt % or more preferably from about 2.5 wt % to about 15 wt % or combinations thereof, relative to the total weight of the composition. Alternatively, the substantially non-odorous fragrance fixative is present in an amount of from about 0.1 wt %, 0.5 wt % or 2.5 wt % to about 15 wt %, 18 wt % or 20 wt %, relative to the total weight of the composition. If there is more than one substantially non-odorous fragrance fixatives, then the ranges provided hereinabove cover the total of all of the substantially non-odorous fragrance fixatives.
The substantially non-odorous fragrance fixatives of the present invention may be a liquid at temperatures lower than 100° C., preferably at ambient temperature. The substantially non-odorous fragrance fixatives 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 as well known to those skilled in the art) can be added to aid in the solubility of the fragrance materials.
Preferably, the composition according to the present invention, wherein the substantially non-odorous fragrance fixatives and fragrance component are present in a weight ratio from about 10:1 to about 1:10, preferably from about 5:1 to about 1:5, or preferably from about 3:1 to about 1:3.
The inventors have discovered that the substantially non-odorous fragrance fixatives can extend the fragrance intensity of the fragrance material over time, preferably over long periods of time 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, i.e., compositions containing no substantially non-odorous fragrance fixatives.
Additionally, the inventors have discovered that the substantially non-odorous fragrance fixatives can extend the fragrance character, preferably the portion of the fragrance profile attributable to the volatile fragrance materials. By “extend” it is meant that the fragrance profile of the composition, preferably the components contributed by the volatile fragrance materials, can be pereceived by the consumer 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, i.e., compositions containing no substantially non-odorous fragrance fixatives.
In one aspect, the present invention provides for a composition comprising a fragrance component present in an amount of from about 0.04 wt % to 30 wt %, preferably 1 wt % to about 30 wt %, more preferably less than about 25 wt %, yet more preferably less than about 20 wt %, yet even more preferably less than about 15 wt %, yet even more preferably less than about 10 wt % or most preferably less than about 8 wt %, relative to the total weight of the composition. Alternatively, the fragrance component is present in an amount of from about 0.04 wt %, 0.3 wt %, 1 wt %, 2 wt %, 5 wt %, 8 wt % or 10 wt %, to about 15 wt %, 20 wt %, 25 wt % or 30 wt %, relative to the total weight of the composition.
Preferably, the compositions of the present invention comprise:

Preferably, the present invention relates to a composition, wherein the composition is in the form of a body splash or a body spray.
Therefore, it goes without saying that the compositions of the present invention encompasses any composition comprising any of the ingredients cited herein, in any embodiment wherein each such ingredient is independently present in any appropriate amount as defined herein. Many such compositions, than what is specifically set out herein, can be encompassed.
In yet another aspect, compositions of the present invention may comprise 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. Preferably, 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 comprise 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.
Suitable entrapment materials for use herein are selected from polymers; capsules, microcapsules and nanocapsules; liposomes, absorbents; cyclic oligosaccharides and mixtures thereof. Preferred are absorbents and cyclic oligosaccharides and mixtures thereof. Highly preferred are cyclic oligosaccharides (see PCT Publication Nos. WO2000/67721 (Procter & Gamble); and WO2000/67720 (Procter & Gamble); and U.S. Pat. No. 6,893,647 (Procter & Gamble)).
In yet another aspect, the present invention provides the solution to the problem of extending the longevity of the fragrance profile of compositions, particularly fine fragrance and cosmetic compositions, preferably fine fragrance compositions, which commonly contain high levels of a volatile solvent. Preferably, the composition according to the present invention, further comprising a volatile solvent present in the amount of from about 10 wt %, 20 wt %, 30 wt %, 40 wt % or 50 wt % to about 90 wt %, 80 wt %, 70 wt % or 60 wt %, relative to the total weight of the composition, and wherein the solvent is a branch or unbranched C1 to C10 alkyl, akenyl or alkynyl 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 10 wt % to about 80 wt %, or even from about 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. 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 yet another aspect, water may be present in any of the compositions of the present invention, and more specifically, it shall not exceed about 40 wt %, preferably about 20 wt % or less, or more preferably about 10 wt % or less, relative to the total weight of the composition. Alternatively, water may be present in an amount of from about 10 wt % or about 20 wt % to about 40 wt %, relative to the total weight of the composition. 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 compositions described herein may include a propellant. Some examples of propellants include compressed air, nitrogen, inert gases, carbon dioxide, and mixtures thereof. Propellants may also include gaseous hydrocarbons like propane, n-butane, isobutene, cyclopropane, and mixtures thereof. Halogenated hydrocarbons like 1,1-difluoroethane may also be used as propellants. Some non-limiting examples of propellants include 1,1,1,2,2-pentafluoroethane, 1,1,1,2-tetrafluoroethane, 1,1,1,2,3,3,3-heptafluoropropane, trans-1,3,3,3-tetrafluoroprop-1-ene, dimethyl ether, dichlorodifluoromethane (propellant 12), 1,1-dichloro-1,1,2,2-tetrafluoroethane (propellant 114), 1-chloro-1,1-difluoro-2,2-trifluoroethane (propellant 115), 1-chloro-1,1-difluoroethylene (propellant 142B), 1,1-difluoroethane (propellant 152A), monochlorodifluoromethane, and mixtures thereof.

The propellant may have a concentration from about 15%, 25%, 30%, 32%, 34%, 35%, 36%, 38%, 40%, or 42% to about 70%, 65%, 60%, 54%, 52%, 50%, 48%, 46%, 44%, or 42% by weight of the total fill of materials stored within the container.
The compositions described herein may be free of, substantially free of, or may include an antiperspirant active (i.e., any substance, mixture, or other material having antiperspirant activity). Examples of antiperspirant actives include astringent metallic salts, like the inorganic and organic salts of aluminum, zirconium and zinc, as well as mixtures thereof. Such antiperspirant actives include, for example, the aluminum and zirconium salts, such as aluminum halides, aluminum hydroxyhalides, zirconyl oxyhalides, zirconyl hydroxyhalides, and mixtures thereof.
In yet another aspect, the composition consists essentially of the recited ingredients but may contain small amounts (not more than about 10 wt %, preferably no more than 5 wt %, or preferably no more than 2 wt % thereof, relative to the total weight of the composition) of other ingredients that do not impact on the fragrance profile, particularly the evaporation rate and release of the fragrance materials. For example, a fine fragrance composition may comprise stabilizing or anti-oxidant agents, UV filters or quenchers, or colouring agents, commonly used in perfumery.
In yet another aspect, the composition of the present invention, depending on its intended use, is a mixture of fragrance materials possibly together with other ingredients such as, for example, perfume carriers. By the term “perfume carrier”, it is meant to include materials which are practically neutral from a perfumery point of view, i.e., which does not significantly alter the organoleptic properties of perfuming components. The perfume carrier may be a compatible liquid or solid fillers, diluents, and the like. The term “compatible”, as used herein, means that the components of the compositions of this invention are capable of being combined with the primary actives of the present invention, and with each other, in a manner such that there is no interaction which would substantially reduce the efficacy of the composition under ordinary use situations. The type of carrier utilized in the present invention depends on the type of product desired and may comprise, but are not limited to, solutions, aerosols, emulsions (including oil-in-water or water-in-oil), gels, and liposomes. Preferably, the carrier is a liquid and will be a solvent such as, for example, dipropyleneglycol, diethyl phthalate, isopropyl myristate, benzyl benzoate, 2-(2-ethoxyethoxy)-1-ethanol, or ethyl citrate (triethyl citrate).
In yet another aspect, the compositions for use in the present invention may take any form suitable for use, more preferably for perfumery or cosmetic use. These include, but are not limited to, vapor sprays, aerosols, emulsions, lotions, liquids, creams, gels, sticks, ointments, pastes, mousses, powders, granular products, substrates, cosmetics (e.g., semi-solid or liquid makeup, including foundations) and the like. Preferably the compositions for use in the present invention take the form of a vapor spray. Compositions of the present invention can be further added as an ingredient to other compositions, preferably fine fragrance or cosmetic compositions, in which they are compatible. As such they can be used within solid composition or applied substrates etc.
The composition may be included in an article of manufacture comprising a spray dispenser. The spray dispenser may comprise a vessel for containing the composition to be dispensed. The spray dispenser may comprise an aerosolized composition (i.e. a composition comprising a propellant) within the vessel as well. Other non-limiting examples of spray dispensers include non-aerosol dispensers (e.g. vapor sprays), manually activated dispensers, pump-spray dispensers, or any other suitable spray dispenser available in the art.
The composition of the present invention according to any embodiments described herein is a useful perfuming composition, which can be advantageously used as consumer products intended to perfume any suitable substrate or surface. As used herein, the term “substrate” means any surface to which the composition of the present invention may be applied to without causing any undue adverse effect. For example, this can include a wide range of surfaces including human or animal skin or hair, paper (fragranced paper), air in a room (air freshener or aromatherapy composition), fabric, furnishings, dishes, hard surfaces and related materials. Preferred substrates include body surfaces such as, for example, hair and skin, most preferably skin.
The composition of the present invention may be used in a conventional manner for fragrancing a substrate. An effective amount of the composition, typically from about 1 μL to about 10,000 μL, preferably from about 10 μL to about 1,000 μL, more preferably from about 25 μL to about 500 μL, or most preferably from about 50 μL to about 100 μL, or combinations thereof, is applied to the suitable substrate. Alternatively, an effective amount of the composition of the present invention is from about 1 μL, 10 μL, 25 μL or 50 μL to about 100 μL, 500 μL, 1,000 μL or 10,000 μL. The composition may be applied by hand or applied utilizing a delivery apparatus such as, for example, vaporizer or atomizer. Preferably, the composition is allowed to dry after its application to the substrate. The scope of the present invention should be considered to cover one or more distinct applications of the composition or the continuous release of a composition via a vaporizer or other type of atomizer.
The present invention provides a method of modifying or enhancing the odour properties of a body surface, preferably hair or skin, comprising contacting or treating the body surface with a composition of the present invention.
The present invention also relates to compositions of the present invention that may be used as consumer products or articles selected from the group consisting of a fabric care product, an air care product, or a home care product. Therefore, according to this embodiment, the present invention provides a method of modifying or enhancing the odour properties of a substrate, preferably fabric, furnishings, dishes, hard surfaces and related materials, comprising contacting or treating the substrate with a composition of the present invention.
In another aspect, the present invention is directed to a method of enhancing the fragrance profile of a composition, preferably by improving the longevity of a character of the composition. The method comprises bringing into contact or mixing at least one substantially non-odorous fragrance fixative with the fragrance material according to the composition of the present invention. Preferably, the character is derived from the volatile fragrance materials in the composition and is characterized by a floral character or aromatic/spicy character. Non-limiting examples of floral character include: lavender-type note, a rose-type note, a lily of the valley-type note, a muguet-type note, a jasmine-type note, a magnolia-type note, a cyclamen-type note, a hyacinth-type note, a lilac-type note, an orange blossom-type note, a cherry blossom-type note, a peony-type note, a lotus-type note, a linden blossom-type note, an osmanthus-type note, a heliotrope-type note, a violet-type note, an orris-type note, a tiare-type, a patchouli-type note and the like.
Non-limiting examples of aromatic (or haerbaceous) and spicy character include: cinnamon, cloves, coriander, ginger, saffron, peppers of various kinds (e.g.: black pepper, pink pepper), caraway, cardamom, anise, tea, coffee, cumin, nutmeg, coumarin, basil, rosemary, thyme, mint, tarragon, marjoram, fennel, sage, and juniper.
Preferably, the fragrance profile or character of the composition of the present invention is detectable by a consumer 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 hours after application of the composition to a substrate as compared to controls.
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. Preferably, the present invention is also directed to a perfuming consumer product or article comprising a composition according to the present invention, wherein the perfuming consumer product is selected from the group consisting of a fabric care product, an air care product or a home care product.
In one aspect, compositions of the present invention comprise at least one substantially non-odorous fixative selected from the group consisting of the materials disclosed in Table 1.
The compounds selected from the group consisting of Table 1 substantially non-odorous fragrance fixatives 1-190, 191, and mixtures thereof, act as a substantially non-odorous fragrance fixative of the present invention. For example, the substantially non-odorous fragrance fixatives, with a fragrance component act to prolong the duration during which the fragrance profile, preferably the characters attributable from the volatile fragrance materials, can be perceived as compared to a control composition in the absence of the fixatives. As another example, the substantially non-odorous fragrance fixatives with a fragrance component, can improve the fidelity of the fragrance profile, preferably the fragrance component derived from the 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 substantially non-odorous fragrance fixatives. While not wishing to be bound by theory, it is believed that the substantially non-odorous fragrance fixatives associate to the fragrance materials and retard evaporation. This may be due to a combination of both the functionality and the structure of the substantially non-odorous fragrance fixatives and the fragrance materials.
Preferably, the “fragrance materials” have been classified as low volatile fragrance materials or volatile fragrance materials by their vapor pressure. For the purpose of clarity, when the fragrance materials refer to a single individual compound, its vapor pressure should be determined according to the reference program cited above. 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.
The nature and type of fragrance materials in the compositions according to the present invention can be selected by the skilled person, on the basis of its general knowledge together with the teachings contained herein, with reference to the intended use or application of the composition and the desired fragrance profile effect. Examples of suitable fragrance materials are disclosed in U.S. Pat. No. 4,145,184, U.S. Pat. No. 4,209,417, U.S. Pat. No. 4,515,705, and U.S. Pat. No. 4,152,272.
(i) Low Volatile Fragrance Materials
Fragrance materials classified as “low volatile fragrance materials” are ones having a vapor pressure less than 0.001 Torr (0.000133 kPa) at 25° C. Preferably, the low volatile fragrance materials form the at most about 30 wt %, wherein the wt % is relative to the total weight of the fragrance component. Preferably, the low volatile fragrance material is selected from at least 1 material, or at least 2 materials, or at least 3 materials, or at least 5 materials, or at least 7 materials as disclosed in Table 2.

(ii) Volatile Fragrance Materials
Fragrance materials classified as “volatile fragrance materials” are ones having a vapor pressure greater than or equal to 0.001 Torr (0.000133 kPa) at 25° C. Preferably, the volatile fragrance materials is present in an amount of from about 70 wt % to about 99.9 wt %, preferably greater than about 80 wt %, or more preferably greater than about 88 wt %, relative to the total weight of the fragrance component. Preferably, the volatile fragrance material is selected from at least 1 material, or at least 2 materials, or at least 3 materials, or at least 5 materials, or at least 7 materials as disclosed in Table 3.
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://scifinder.cas.org/scifinder/view/scifinder/scifinderExplore.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 14.02). 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 fixatives 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.
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 difference scale below are any two 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 panelists are used to evaluate a given product and its control.
(a) Fragrance Intensity:
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.
(b) Fragrance Character:
The panelists are asked to assess the fragrance character in one of 2 ways:
The results of the panelists are averaged and then analysed 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 Tukey correction for multiple comparisons. The p-values for the product differences were obtained, with p-values<0.05 indicating a statistical difference between the two products at 5% significance (or 95% confidence).
The following test is carried out to demonstrate the improved or enhanced longevity of a fragrance profile of a composition of the present invention vs. a control. In particular, the test measures the effect of a substantially non-odorous fragrance fixative on the evaporation rate of one or more fragrance materials (e.g., 10 PRMs) formulated in a composition. The evaporation response of the fragrance materials to the fixative, as a function of time, is measured through the use of gas chromatography (“GC”).
The following test is carried out to demonstrate the character retention over time of a fragrance composition of the present invention vs. a control. It is necessary for the test and control samples to be run at approximately the same time to ensure that ambient conditions are the same. The test measures the presence of one or more fragrance materials in the headspace formed in a sealed vial by the test composition, after set evaporation times. The fragrance profile in the headspace is measured at specific time points through the use of headspace (“HS”) gas chromatography (“GC”).

Compositions disclosed in Tables 18(a)-18(c), and 19(a) are applied to glass slides in accordance with the protocol described in the Method Section and a panel of 6-11 experienced panelists evaluated 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 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.
(a) Effects of the Substantially Non-Odorous Fragrance Fixatives on Single Fragrance Material Compositions
(b) Effects of Substantially Non-Odorous Fragrance Fixatives 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 Component) Vs. Compositions Having Traditional Levels of Low Volatile Fragrance Materials (Greater than 30 wt % Relative to the Total Weight of the Fragrance Component) and No Substantially Non-Odorous Fragrance Fixative
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 fixative and reduced levels of low volatile fragrance materials for any one of the inventive Compositions A1 on fragrance profile longevity versus control Compositions C1 in the absence of the substantially non-odorous fragrance fixatives. Alternatively, the results show the effect of the substantially non-odorous fragrance fixative and reduced levels of low volatile fragrance materials for any one of the inventive Compositions A1 on fragrance profile longevity versus traditional Compositions B1 in the presence of the substantially non-odorous fragrance fixative.
Fragrance profile longevity, particularly intensity of the characters attributable to the volatile fragrance materials, are maintained for up to at least 6 hours in the presence of the substantially non-odorous fragrance fixative whilst it drops in the absence of the substantially non-odorous fragrance fixative.
(c) Effects of the Substantially Non-Odorous Fragrance Fixatives on the Fragrance Profile Fidelity of Compositions Having Reduced Levels of Low Volatile Fragrance Materials (Between 10 to 30 wt % Relative to the Total Weight of the Fragrance Component) Vs. Compositions Having Traditional Levels of Low Volatile Fragrance Materials (Greater than 30 wt % Relative to the Total Weight of the Fragrance Component) and No Substantially Non-Odorous Fragrance Fixative
Panelists are also asked to score the composition for the fragrance profile fidelity. In particular, the panelists are asked to score the dominance of the floral character attributable to the volatile fragrance materials on a scale of 0 to 3 wherein 0 represents not detectable and 3 represents it being the dominant character. The results of the panel test are then averaged. The results show the effect of the substantially non-odorous fragrance fixative for the inventive Compositions A1 on fragrance profile fidelity versus control Compositions C1 in the absence of the substantially non-odorous fragrance fixative.
Fragrance profile fidelity are maintained by the substantially non-odorous fragrance fixative over time for up to 6 hours in the presence of the substantially non-odorous fragrance fixative whilst it drops in the absence of the substantially non-odorous fragrance fixative (data not shown).
Using the analytical evaporation Test Method 3, it is possible to measure the amount of a volatile fragrance material or each component of a perfume mixture that remains as the fragrance mixture evaporates. Test compositions may comprise any one of the volatile fragrance material as disclosed in Table 3 and a substantially non-odorous fragrance fixative, as disclosed in Table 1. Alternatively, test compositions may comprise a mixture of 10 volatile perfume materials, as disclosed in Table 11 (Fragrance Example 6), and a substantially non-odorous fragrance fixative, as disclosed in Table 1. Examples of suitable test compositions include the compositions disclosed in Table 18(d), and Compositions MOD1 to MOD43 in Table 19(b) and Compositions in Table 19(c). The test compositions are introduced in the aluminum containers at the set temperature for pre-determined periods of time in accordance with the protocol described in Test Method 3.
For Compositions MOD1 to MOD43, indole is one of the components of the 10 PRMs mixture of Table 11. Control compositions containing the full 10 PRMs, or one component (e.g., indole), without the substantially non-odorous fragrance fixative are run alongside the test compositions. The average profile for the control composition is plotted against the individual profile for the indole component from the test composition containing the 10 PRMs mixture of Table 11 with the substantially non-odorous fragrance fixatives. The error associated with the method is determined by running replicate evaporation experiments on the control composition. An average evaporation profile of the control composition as well as the 95% confidence interval at each time point are calculated from the replicates.
It is useful to consider the difference (Δ) in the % of remaining fragrance material between each of the test composition (MOD) and their respective control composition (REF) at each experimental time points (e.g., 30 mins, 60 mins and 180 mins) to determine the effect of the substantially non-odorous fragrance fixative on the volatile PRMs in a mixture. The difference (Δ) in the % of remaining of a given fragrance material is calculated as follows:
Δ=% remaining of given fragrance material in test composition (MOD)−% remaining of same fragrance material in control composition (REF)
The difference (Δ) can then be plotted (data not shown) for each of the perfume materials in the mixture at each of the time points. For ease of reference, the applicant has summarize the effect of the substantially non-odorous fragrance fixative on only one volatile fragrance component (e.g., indole) of the mixture, to serve as a representative of all of the volatile fragrance materials.
