Description

[0001]23.42 FRAGRANCE COMPOSITIONS AND METHODS OF DELIVERING THE SAME FIELD The present disclosure relates generally to fragrance compositions and methods of delivering the fragrance compositions. More particularly, the disclosure relates to fragrance compositions comprising at least one gellant, at least one skin feel modifier, and at least one fragrance ingredient, and in the form of transparent or translucent gel. BACKGROUND Perfumes have been used for thousands of years. The industrial production of essential oils and the synthesis of odorous substances have improved the availability and the range of application of perfumes. While the industry’s focus on creating new fragrances and fixing the base note to increase clinging and adhesion of the perfume to the user’s keratin surfaces has never changed, consumers are demanding more composition improvements such as optimizing the delivery method, improving the skin feel that the perfume creates when applied on the skin, and tweaking the transparency index of the fragrance solution. The fragrance composition form of gel has thus attracted much attention due to its unique skin feels and aesthetics. However, fragrance gels have their own technical challenges to meet the consumers’ expectations. For example, consumers desire transparent and translucent fragrance compositions, but it is difficult to make those fragrance gels transparent or translucent because the majority fragrance compositions are hydroalcoholic and have high amount hydrophobic fragrance ingredients. In addition, the fragrance gels have very different scent emission profiles from what other composition forms have, thus further tuning is typically required for fragrance gels to meet consumers’ needs. Disclosed herein are unexpected fragrance compositions that comprise at least one gellant, at least one skin feel modifier, and at least one fragrance ingredient, and are in the form of transparent or translucent gel. DETAILED DESCRIPTION The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. Except in operating and comparative examples, or where otherwise explicitly indicated, all numbers in this description indicating amounts or ratios of material or conditions of reaction, physical properties of materials and / or use are to be understood as modified by the word “about”. All amounts are by weight of the final composition unless otherwise specified. As used herein, the term “perfume oils” refers to substances known to modify the smell of a product or provide a smell to a person, including but not limited to essential oils, synthetic fragrances, or mixtures thereof. As used herein, the term “Log P” value of a compound refers to the logarithm of its partition coefficient (P), and is defined as a particular ratio of the concentrations of a solute between the two solvents (in a bi-phase of liquid phases), for un-ionized solutes, between n- octanol and water (cLog(octanol / water), which is calculated as Log P (Partition Co-efficient) = Log ([organic] / [aqueous]), indicating the concentration of solute in the organic and aqueous partition. cLog P is a calculated Log P value. The higher the cLog P value of a compound is, the more hydrophobic the compound is. In traditional fragrance development, the high amount of water present in the composition may reduce the transparency of the fragrance composition, resulting in a cloudy or milky appearance. It is well understood in the perfume industry that the higher the water amount is, the harder it is to achieve a stable fragrance composition. Advantageously, the fragrance composition is translucent or transparent. The fragrance compositions are stable and storable over a wide range of temperatures and conditions. The fragrance compositions provide full olfactory restitution of fragrance oil connected to long-term olfactory stability. The fragrance compositions may stay stable and clear without any precipitation or cloudiness for at least eight weeks when stored at 40oC.

Various methods of treatment, application, regulation, or improvement may utilize the aforementioned fragrance compositions. Application of the present fragrance compositions can occur on any keratin surface. keratin surfaces of the most concern tend to be facial skin surfaces, hand and arm skin surfaces, foot and leg skin surfaces, and neck and chest skin surfaces (e.g., décolletage). Preferred keratin surfaces are hand and arm skin surfaces. The fragrance composition may be applied along with other products or formulations. The form of the composition or the acceptable carrier should be selected to facilitate localized application. While certain embodiments of the present invention contemplate applying locally, it will be appreciated that compositions of the present invention can be applied more generally or broadly to one or more skin surfaces. Likewise, the compositions can be applied as a continuous spray, lotion, or a spray. The formulation may be paired with multiple fragrance notes and may also be personalized and / or layered benefitting individual customer needs. Such 23.42 pairing may be achieved by adding additional fragrance notes or fragrance accords to satisfy the individual’s needs, resulting in a personalized fragrance composition that is unique to the consumer. When the fragrance composition is a fragrance gel, the delivery form of the fragrance composition may have critical impacts on the sensory skin feels and how the fragrance ingredients are released. For each delivery form, the dosage amount may also have significant impacts on the same end results desired by the consumers. Because the optimized delivery form and dosage amount of a fragrance composition is dependent on the specific physical and chemical properties of the fragrance composition, formulating a method of delivering the fragrance composition is scientifically challenging. Preferably, the fragrance composition may have a viscosity ranging from about 500 cP to 4500 cP, preferably from about 1000 cP to 4000 cP, more preferably greater than 1200 cP and less than 3600 cP, most preferably from about 2000 cP to about 3500 cP, particularly preferably from about 2500 cP to about 3200 cP, most particularly preferably from about 2800 cP to about 3000 cP; wherein the viscosity is measured at room temperature at 30 RPM. The fragrance composition may be applied at least once a day, twice a day, or on a more frequent daily basis, during a treatment period. The fragrance composition may be applied onto keratin surfaces by using patches, droplet dispensing devices (nonlimiting examples are dropper bottles and pipette droppers), spray devices, diffusing devices, or other delivery devices. Droplet dispensing devices are preferred. When being applied onto keratin surfaces by using droplet dispensing devices, each application of the fragrance composition may comprise the step of dispensing a single droplet onto a single location of the keratin surface, dispensing multiple droplets onto a single location 23.42 of the keratin surface, dispensing multiple droplets onto multiple locations of the keratin surfaces, or combinations thereof. In some embodiments, the fragrance composition described herein is in the form of a skin lotion, clear lotion, milky lotion, cream, gel, foam, ointment, paste, emulsion, spray, conditioner, tonic, cosmetic, lipstick, foundation, nail polish, after-shave, or the like, which is intended to be left on the skin or other keratinous tissue for some aesthetic, prophylactic, therapeutic or other benefits (i.e., a “leave-on” composition or skincare composition). After applying the composition to the keratinous tissue (e.g., skin), it is preferably left on for a period of at least about 2 minutes, 5 minutes, 15 minutes, more preferably at least about 30 minutes, even more preferably at least about 1 hour, even more preferably for at least several hours, e.g., up to about 12 hours. Any part of the external portion of the human body, that is not sensitive may be applied with the fragrance compositions. Preferably, the fragrance gel may be applied onto the keratin surfaces in the form of droplet. Each droplet of the fragrance gel for such application may be at a dosage amount of greater than 0.01 gram and less than 0.48 gram, preferably at a dosage amount ranging from about 0.05 gram to about 0.4 gram, more preferably at a dosage amount ranging from about 0.1 gram to about 0.3 gram. Each application of the fragrance gel in the form of droplet onto keratin surfaces may comprise the step of administrating a single droplet onto a single location of the keratin surface, administrating multiple droplets onto a single location of the keratin surface, administrating multiple droplets onto multiple locations of the keratin surfaces, or combinations thereof. When being applied onto desired keratin surfaces in the form of droplet, the fragrance gel may be 1) directly administrated onto the desired keratin surface, 2) first applied to a finger, a palm, or an item with an application surface, then rubbed onto the desired keratin surface, 3) first directly administrated onto the desired keratin surface, then being spread by a finger, a 23.42 palm, or an application device, or 4) combinations thereof. Preferably, the fragrance gel is directly administrated onto the desired keratin surface. More preferably, the method of delivering the fragrance gel further comprises a step of spreading the fragrance gel by rubbing the administrated fragrance gel on the desired keratin surface. EXAMPLES Example 1: Fragrance Compositions The example compositions (Samples 1-15 in Tables 1-3, all ingredients amount were shown in their weight percentages relative to the total weight of the fragrance composition) were prepared as described below: Step 1: except for the gellant, all ingredients including the aqueous medium, alcohol, skin feel modifier, fragrance oil, and so on, were added one by one at room temperature and stirred at 2000 rpm under overhead propeller till a clear homogenous mixture was obtained. Step 2: the gellant powder was sprinkled into the resulting mixture of Step 1 while the speed was maintained at 2000 rpm. Step 3: the resulting mixture of Step 2 was then stirred at the reduced speed of 800 rpm till a gel was formed. The process described herein may be modified to adjust the mixing speed. The prepared sample gels were filled into a transparent container and stored for one week. An experienced evaluator then visually evaluated the samples under natural lighting and gave each sample a transparency score based on each sample’s profile. The formula viscosity was measured by Brookfield Viscometer (Spindle LV 4) at room temperature at 30 RPM. 23.42 The Fragrance Oils were measured to have a cLog P value of 4.2 for Fragrance Oil 1, 3.6 for Fragrance Oil 3, and 2.98 for Fragrance Oil 4. According to the obtained transparency scores, Samples 1, 9, 10, 11, 14, and 15 all showed crystal-clear gels; Samples 4, 5, and 6 showed clear gels but were less clear than Samples 1, 9, 10, 11, 14, and 15. Samples 2 and 13 were clear but they were regular hydroalcoholic solutions, not gels. Above gel visual properties showed Polyacrylate Crosspolymer-6’s superiority (Samples 1 and 6) over other gellants such as Hydroxypropylcellulose (Sample 3), Carbomer (Samples 7 and 8), and Sodium Hyaluronate (Sample 12). The comparison of Samples 1 and 6 showed that when everything else was the same, the amount of the fragrance oil had impacts on the gel’s overall visual properties (Sample 1 was clearer than Sample 6). The crystal-clear gels (Samples 1, 9, 10, 11, 14, and 15) were tested for viscosity (as shown in Tables 1, 2, and 3, respectively).

The panel of fragrance evaluators evaluated and graded the fragrance intensity (score from 0 to 5, with 0 meaning minimum odor intensity and 5 meaning strongest odor intensity), at time of 0 hour and after 6 hours air-dry at the bench table with minimum air flow at room temperature. For skin feel evaluations, a single-use test of each of samples 1, 14, and 15 was done on the panelist’s skin for overall liking (scored from 0-5 with 0 dislike at all, 5 as the like the best among these samples), right after the droplet was dosed on the skin and after the sample was dried down at room temperature. For all evaluations, the dosage amount was measured and recorded. All results were recorded in Table 4. 23.42 Table 3: Fragrance Compositions Samples CTFA name 1 14 15Gellant Polyacrylate Crosspolymer-6 1 0.5 1.2 5 3 5 5 5 .5 s 00 r, or at 1200 cP (Sample 14) or lower, the fragrance intensity and skin feel suffered inferior results; and when the formula viscosity was in appropriate range (Sample 1, at 2900 cP), the formula showed the fragrance intensity and skin feel. Also, for the same formula (Sample 1), the dosage amount also affected the end results: high dosage amount (0.48 gram per droplet) gave a better initial fragrance intensity score, but suffered inferior skill feel; low dosage amount (0.05 gram per droplet) showed better skin feel but the fragrance intensity, especially the longer term (t=6 hours) fragrance intensity, suffered; the appropriate dosage amount of 0.10 gram per droplet showed the best overall results of fragrance intensity and skin feel.
