Patent Application
20200397685
A fragrance is a mixture of individual components both aromatic and non-aromatic. Each fragrance component interacts both with other components within the mixture, and with the chemical and structural nature of the environment to determine the aesthetic and the physical characters of the final system. The combined talents of the perfumer and the technical staff, working closely together, are needed to create a fragrance mixture that will provide a top note, a middle note and a base note. The top note is characterized by the upfront refreshing quality when the fragrance is applied, while the base note is the scent that continues to linger and stays for a long time with the wearer. The middle note is what bridges both the top note and the base note, providing a pleasant transition from the top note to the base note.
One of the components used in the fragrance mixture is called a fixative and is generally used to prolong the fragrance effect of the fragrance mixture by delaying the evaporation rate of volatile materials in the fragrance mixture. This is achieved through hydrogen bonding of the fixative component with the other components resulting in an overall lower vapor pressure for the fragrance mixture. A good fixative generally will not be odorous by itself, will be miscible in polar and nonpolar solvents, and will have a higher boiling point than the other components in the fragrance mixture. Typical examples of fixatives are floral and botanical absolutes, concretes and oleo resin, animal secretions and extracts, macrocyclic musks, and nitro musks.
It is well known that fragrance fixatives (also referred to as fragrance carriers) are generally synthetically produced chemicals and those that are natural can distort the nature or character of the fragrance being fixed.
Despite advances in fragrance research, there is still a scarcity of compounds that are both potent and efficacious fragrance fixatives without interfering with the intended scent. These needs and other needs are satisfied by the present disclosure.

General Discussion
In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, embodiments of the present disclosure, in some aspects, relate to fragrance compositions and products including fragrance compositions.
In general, embodiments of the present disclosure provide fragrance compositions including at least one fragrance compound as well as a glycoside. According to the disclosed embodiments, the glycoside can comprise one or more steviol-based glycosides including Steviol glycosides, glucosylated Steviol glycosides, derivatives of a Steviol glycoside, derivatives of a glucosylated Steviol glycoside, or combinations thereof.
Advantageously, the addition of a glycoside provides enhanced duration of a fragrance. Steviol-based glycosides have been extensively tested and are known to be safe for humans.
The use of Steviol glycosides, glucosylated steviol glycosides and its derivatives as a fixative in a fragranced products increases the lasting power of the fragrance dramatically. The increase of the lasting power does not distort the character of the fragrance. In other words, the perceived fragrance of a fragrance composition comprising the glycoside is substantially the same as the perceived fragrance of a similar fragrance composition that lacks the glycoside component. These properties are a unique and unexpected character of a steviol-based glycoside.
According to various embodiments of the present disclosure the fragrance composition comprises about 0.001 to about 5 weight %, or about 0.01 to about 3%, or about 0.10 to about 1%, of the glycoside, based on the total weight of the fragrance composition. Advantageously, the inclusion of a steviol-based glycoside in a fragrance composition can prolong the time for which a fragrance is perceivable, from about 8 hours to 48 hours longer than compositions without the steviol-based glycoside. In some embodiments, the fragrance composition including the glycoside can enable a reduction in the amount of fragrance compound (e.g. from about 10% up to 30% less) needed in a composition to provide the same perceived fragrance. Such benefits can reduce the cost of manufacturing products that include fragrance, such as perfumes, cosmetics, and household products. Advantageously, the inclusion of the steviol-based glycoside can simultaneously reduce the amount of fragrance compound needed to detect a fragrance and increase the duration for which the fragrance can be detected.
In various embodiments, the glycoside can include diterpines (e.g. rubusoside, Rebaudioside A, Rebaudioside B, Rebaudioside C, Rebaudioside D, Rebaudioside E, Rebaudioside F, Rebaudioside M, Rebaudioside N, Rebaudioside O, dulcoside A, or enzymatically treated stevia extract). The inclusion of a Steviol-based glycoside does not interfere with the perceived fragrance of a composition. It is envisioned that other natural high-potency sweeteners and/or their derivatives could be used, including but not limited to, triterpines (e.g. monkfruit) and glycyrrhizin (e.g. licorice root extract).
The glucosylated Steviol glycoside can have a low degree of glycosylation, where number of glucose molecules attached to the steviol glycosides is from one to five. Alternatively, the glucosylated Steviol glycoside can have a high degree of glycosylation, where number of glucose molecules attached to the steviol glycosides is from six to twenty.
The Steviol glycosides, glucosylated steviol glycosides and their derivatives of the present disclosure can be extracted from the plant Stevia rebaudiana bertoni. The process of extraction is well established. According to one process, the leaves of the plant are soaked in water for a number of hours, resulting in an aqueous solution that is rich in glycosides. Next, the aqueous solution can be processed in a series of steps of filtration to remove unwanted components. Finally, the aqueous solution is spray dried, resulting in a white-yellowish powder. For glucosylated steviol glycosides, this white-yellowish powder is further dissolved in water and processed with enzymes after adjusting the pH and temperature together with a carbohydrate source (e.g. starch or dextrins). The derivatives are generally produced by reacting chemicals with Stevia extract. There are no known examples of using Steviol glycosides, glucosylated steviol glycosides, or their derivatives as a fixative in fragranced product.
The addition of an effective amount of steviol-based glycosides to fragrance mixtures resulted in fragrance fixing, without detectably altering the fragrance of the mixtures. Neither Steviol glycosides, glucosylated steviol glycosides, nor their derivatives have a detectable fragrance, so their use as fragrance-enhancing or fragrance fixing components in topical or non-food applications has not heretofore been appreciated.
Although not intending to be bound by theory, it is hypothesized that the steviol-based glycosides are nanoencapsulating the less-soluble fragrance compounds in the mixture, allowing them to more slowly evaporate, thereby elongating the fragrance availability.
Interesting effects of steviol glycosides have been shown in other fields such as pharmaceuticals, including increasing absorption of insoluble or poorly soluble bioactive materials. Low water solubility of bioactive compounds, resulting in their use at very high concentrations to deliver a desired pharmacological effect, is problematic and results in negative side effects of the medicines among subjects. Surfactants can be used, in part, to increase solubility/bioavailability of bioactive compounds to the target cells and reduce the over stimulation of non-target cells incidentally exposed during a medical treatment. Sonication at high temperature and homogenization at high temperature and pressure of aqueous solutions of steviol glycoside “surfactant” and bioactive compounds are two techniques shown to further stabilize the systems to the extent that they are resistant to changes in pH, temperature and remain intact after drying and reconstitution.
In accordance with various embodiments of the present disclosure, fragrance compounds can be any ingredient or combination of ingredients providing an odor to the fragrance composition or to an object or product to which it is provided. The fragrance compounds can be natural, synthetic, or a combination thereof. Fragrance compounds can include ethereal oils and extracts (e.g. castoreum, costus root oil, oak moss absolute, geranium oil, jasmine absolute, patchouli oil, rose oil, sandalwood oil, ylang-ylang oil), alcohols (e.g. citronellol, Ebanol™, eugenol, geraniol, Super Muguet™, linalool, phenylethyl alcohol, Sandalore™, terpineol or Timberol™), aldehydes and ketones (e.g. Azurone™, α-amylcinnamaldehyde, Georgywood™, hydroxycitronellal, Iso E Super™, Isoraldeine™, Hedione™, maltol, methyl cedryl ketone, methyl ionone or vanillin), ether and acetals (e.g. Ambrox™, geranyl methyl ether, rose oxide or Spirambrene™), esters and lactones (e.g. benzyl acetate, cedryl acetate, γ-decalactone, Helvetolide™, Serenolide™, γ-undecalactone or vetivenyl acetate), macrocycles (e.g. ambrettolide, ethylene brassylate or Exaltolide™), and heterocycles (e.g. isobutylchinoline).

Unless otherwise specified all percentages noted in the examples are weight/weight. In the examples provided below, panel studies were conducted to evaluate the efficacy of steviol glycosides as a fragrance fixative, and to determine whether the addition of the glycosides negatively affected participants' preferences for fragrances. Fragrance strength and duration is not easily measured quantitatively, so rather can be characterized based on human evaluations. To qualitatively evaluate fragrance, panel studies were conducted as follows. In each of the panels, there were ten participants. For non-skin applications, a blotting paper (perfume test strip, or Mouillette) was dipped one third of its length into the fragrance composition and left in the open air. Panel participants were asked to evaluate the fragrance over a 48-hour period, with observations recorded at 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, and 48 hours. For skin applications, a single spray was applied from a distance of 6 inches to the participant's wrist and allowed to dry for 20 seconds. The panel participants were asked to evaluate the fragrance, with observations recorded every 2 hours for 8 hours. Participants indicated preference by indicating a preference for one scent over the other and ranked the strength of the scents by stronger, equal, or weaker.
In this example, an exemplary fragrance composition comprising a fragrance compound and a steviol-based glycoside was prepared and compared to a control composition comprising the same fragrance compound, but no glycoside. The recipes for comparative composition 1-A and exemplary fragrance composition 1-B are provided in Table 1.
In panel studies, in periods ranging from one to 48 hours, 90% of the panelists observed longer lasting properties (e.g. about 36 hours) on skin in the exemplary formulation with 0.5% Rebaudioside A 80% (1-B) compared to the formulation without steviol glycosides (1-A). On tests on perfume blotters that lasted 48 hours, 90% of the panelists made the same observation.
In this example, an after-bath splash product was prepared having an exemplary fragrance composition comprising a fragrance compound and a steviol-based glycoside and compared to an after-bath splash product having a control composition comprising the same fragrance compound, but no glycoside. The recipes for comparative bath-splash composition 2-A and exemplary bath-splash composition 2-B are provided in Table 2.

In panel studies, 90% of the panelists observed longer lasting properties on skin in the exemplary formulation with 0.1% Rebaudioside A 97% (2-B) compared to the comparative formulation without the steviol glycosides (2-A). The panelists observed that in the exemplary formulation (2-B), the fragrances lasted 48 hours longer. On tests on perfume blotters, 100% of the panelists made the same observation.
In this example, an exemplary fragrance composition comprising a fragrance compound and a steviol-based glycoside was prepared and compared to a control composition comprising the same fragrance compound, but no glycoside. The recipes for comparative composition 3-A and exemplary fragrance composition 3-B are provided in Table 3.
In panel studies, 90% of the panelists preferred the fragrance of the exemplary formulation with Rebaudioside A 50% (3-B) on skin to that of the comparative composition 3-A. On perfume blotters, 100% of the panelists preferred the fragrance of the exemplary formulation 3-B.
In this example, an exemplary fragrance composition comprising a fragrance compound and a steviol-based glycoside was prepared and compared to a control composition comprising the same fragrance compound, but no glycoside. The recipes for comparative composition 4-A and exemplary fragrance composition 4-B are provided in Table 4.
In panel studies, 90% of the panelists preferred the fragrance of the cologne including the Steviol Glycosides (GSG 80%) (4-B) on skin as compared to the comparative cologne that excluded the glycoside. On perfume blotters, 90% of the panelists preferred the fragrance of the exemplary cologne product 4-B.
In this example, a shave lotion was prepared having an exemplary fragrance composition comprising a fragrance compound and a steviol-based glycoside and compared to a shave lotion having a control composition comprising the same fragrance compound, but no glycoside. The recipes for comparative shave lotion composition 5-A and exemplary shave lotion fragrance composition 5-B are provided in Table 5.
In panel studies over periods ranging from one to twenty-four hours, 90% of the panelists determined longer lasting properties on skin for the product with Steviol Glycosides (GSG 90%) (5-B) compared to the product without this steviol glycosides (5-A). On perfume blotters, 80% of the panelists preferred the lasting quality of the (5-B) product.
In this example, a hand cream was prepared having an exemplary fragrance composition comprising a fragrance compound and a steviol-based glycoside and compared to a hand cream having a control composition comprising the same fragrance compound, but no glycoside. The recipes for comparative hand cream composition 6-A and exemplary hand cream composition 6-B are provided in Table 6.

Over a period of one to four hours, the hand cream with Steviol Glycosides (GSG 90%)(6-B) was judged by 80% of the panelists to exhibit a fragrance having greater intensity and longer lasting power than the fragrance of the comparative hand cream without the steviol glycoside (6-A).
In this example, a soap bar was prepared having an exemplary fragrance composition comprising a fragrance compound and a steviol-based glycoside and compared to a soap bar having a control composition comprising the same fragrance compound, but no glycoside. The recipes for control soap bar composition 7-A and exemplary soap bar composition 7-B are provided in Table 7.
In wash use tests, 90% of the panelists judged the intensity of fragrance in soap bars containing Steviol Glycosides (GSG 90%) (7-B) to be greater than that in bars without the Steviol Glycosides (GSG 90%). In the wash use test, half of the panelists were instructed to wash their hands using their normal handwashing procedure with soap bars containing steviol glycosides while the other half of the panelists used the soap bars without the steviol glycosides.
In this example, an exemplary fragrance composition comprising a fragrance compound and a steviol-based glycoside was prepared and compared to a control composition comprising the same fragrance compound, but no glycoside. The recipes for comparative composition 8-A and exemplary fragrance composition 8-B are provided in Table 8.
In panel tests on skin and perfume blotters, 40% of the panelists judged exemplary Formula 8-B to have a stronger fragrance than comparative Formula 8-A. The remaining 60% judged 8-A and 8-B to have equivalent fragrance. This indicates that by using the glycoside in the fragrance composition, it may be possible to reduce the amount of fragrance compound without diminishing the perceived fragrance of the fragrance composition. Use of such reduced concentration of perfume oils without adverse effect on perception of odor will provide significant savings in material costs.
In this example, an exemplary fragrance composition comprising a fragrance compound and a steviol-based glycoside was prepared and compared to a control composition comprising the same fragrance compound, but no glycoside. The recipes for comparative composition 9-A and exemplary fragrance composition 9-B are provided in Table 9.
In panel tests, 40% of the panelists judged Formula 9-B with Steviol Glycosides (Reb A 80%) to have a stronger fragrance than Formula 9-A without the Steviol Glycosides (Reb A 80%); 30% found no difference between the two fragrances; and 30% judged 9-A to have a stronger fragrance. Thus 70% of the panelists accepted the exemplary fragrance composition having reduced perfume oil concentration as equal to or better than the comparative composition. This indicates that by using the glycoside, it may be possible to reduce the amount of fragrance compound without diminishing the perceived fragrance, but with possible attendant major cost savings. Tests were run on skin and blotters.
It should be noted that ratios, concentrations, amounts, and other numerical data may be expressed herein in a range format. It is to be understood that such a range format is used for convenience and brevity, and thus, 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. To illustrate, a concentration range of “about 0.1% to about 5%” should be interpreted to include not only the explicitly recited concentration of about 0.1 wt % to about 5 wt %, but also include individual concentrations (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.5%, 1.1%, 2.2%, 3.3%, and 4.4%) within the indicated range. In an embodiment, “about 0” can refer to 0, 0.001, 0.01, or 0.1. In an embodiment, the term “about” can include traditional rounding according to significant figures of the numerical value. In addition, the phrase “about ‘x’ to ‘y’” includes “about ‘x’ to about ‘y’”.
It should be emphasized that the above-described embodiments of the present disclosure are merely possible examples of implementations, and are set forth only for a clear understanding of the principles of the disclosure. Many variations and modifications may be made to the above-described embodiments of the disclosure without departing substantially from the spirit and principles of the disclosure.
