Description

"METHOD FOR PREPARING A HIGH-PERFORMANCE FRAGRANCE COMPOSITION, HIGH-PERFORMANCE FRAGRANCE COMPOSITION AND HAIR CONDITIONING PRODUCT" State of the art

[0001] Attempts have been made to create fragrance accords and compositions suitable for specific product applications with superior or enhanced properties, bringing benefits to the consumer. For example, WO 1999 / 065458 defines two categories of fragrance ingredients to be formulated into high-impact accords based on a combination of boiling point, partition coefficient (ClogP), and measured odor detection limits. These accords can optionally be encapsulated in starch to provide a fragrance boost to a powdered detergent when dispersed in water. US Patent 9,222,055 provides a high-intensity fragrance that includes 75% to 100% of at least two key fragrance ingredients with boiling points between 100 °C and 300 °C at a pressure of 760 mmHg, molecular weights in the range of 70 to 175 atomic mass units, and ClogP values ​​between 0 and 4.US patent 2005 / 0003975 also discloses perfume compositions composed of high-impact accord perfume ingredients classified by boiling point, calculated CLogP, and odor detection thresholds. Document EP 196454 describes fragrance compositions for use in consumer products to reduce allergic reactions.

[0002] Despite the many attempts described above, there is still a need to create high-performance, long-lasting fragrances, particularly for dry hair. The present invention meets this need in the art. Brief Description of the Invention

[0003] This invention is a high fragrance composition Petition 870250080574, dated 09 / 08 / 2025, p. 89 / 125 2 / 31 performance composed of at least five fragrance ingredients, each having an analytical deposition value and a retention value, wherein the combined analytical deposition value and retention value of each fragrance fall within a range established by formula (I): 60% < R + 5 D<150% (I), where “R” is the experimentally determined fragrance retention percentage in a dry hair sample after 10 hours and “D” is the experimentally determined fragrance deposition percentage in a wet hair sample, where the at least five fragrances include: (i) at least two fragrance ingredients with an intensity value in the range of 40 to 60, wherein each of the fragrance ingredients is present in a dosage greater than 2% by weight of the high-performance fragrance composition, and (ii) at least three fragrance ingredients with an intensity value greater than 60, wherein each of the fragrance ingredients is present in a dosage greater than 1% by weight of the high-performance fragrance composition, wherein the intensity value of (i) and (ii) is determined on a scale of 0 to 100.

[0004] In one aspect, the high-performance fragrance composition includes at least two to four fragrance ingredients with an intensity value in the range of 40 to 60, wherein each of the fragrance ingredients is present in a dosage greater than 2% by weight of the fragrance composition.

Petition 870250080574, dated 09 / 08 / 2025, p. 91 / 125 4 / 31

[0010] Additionally, the use of “a” or “an” is used to describe elements and components described in this document. This is done merely for convenience and to give a general sense of the scope of the invention. This description should be read to include one or at least one, and the singular also includes the plural, unless the contrary is obvious.

[0011] Unless otherwise defined, all technical and scientific terms used in this document have the same meaning as commonly understood by a person skilled in the art to which this invention pertains. In case of conflict, this descriptive report, including definitions, shall prevail. Although methods and materials similar or equivalent to those described in this document may be used in the practice or testing of embodiments of the present invention, suitable methods and materials are described below. Furthermore, the materials, methods, and examples are for illustrative purposes only and are not intended to be limiting.

[0012] The present disclosure illustratively described in this document may be adequately practiced in the absence of any element or elements, limitation or limitations not specifically disclosed in this document. Although compositions and methods are described in this document in terms of “comprising” various components or steps, the compositions and methods may also “consist essentially of” or “consist” of the various components or steps, unless otherwise stated.

[0013] This invention is a high-performance fragrance composition that exhibits long-lasting performance on dry hair for at least 10 hours. The fragrances were selected based on their deposition and retention on hair samples. A set of fragrances demonstrated adequate deposition and retention on dry hair for at least 10 hours and is defined by the analytical values ​​of deposition and retention using the Petition 870250080574, dated 08 / 09 / 2025, page 92 / 125 5 / 31 formula (I): 60% < R + 5 D < 150% (I) where “R” is the experimentally determined fragrance retention percentage in a dry hair sample after 10 hours and “D” is the experimentally determined fragrance deposition percentage in a wet hair sample. The perceived intensity (scale of 0 to 100) of fragrances within this class (i.e., fragrances defined by formula (I)) was then evaluated in rinse-out conditioner applications, and certain fragrances demonstrated superior fragrance intensity formulations in dry hair. Based on this analysis, a set of key characteristics was developed to produce a high-performance fragrance and a rinse-out conditioner product containing it.

[0014] Thus, this invention provides a high-performance fragrance composition and a rinse-out conditioning product containing the same, wherein the fragrance composition includes at least five fragrance ingredients, each fragrance ingredient having an analytical deposition value and a retention value, wherein the combined analytical deposition value and retention value of each fragrance fall within a range set forth by formula (I): 60% < R + 5 D < 150% (I), where “R” is the experimentally determined fragrance retention percentage in a dry hair sample after 10 hours and “D” is the experimentally determined fragrance deposition percentage in a wet hair sample. In some respects, the high-performance fragrance composition and the rinse-out conditioner product containing it include at least five, at least six, at least seven, at least eight, at least nine, or at least 10 or more Petition 870250080574, dated 08 / 09 / 2025, page 93 / 125 6 / 31 fragrance ingredients having a combined analytical deposition value and retention value that fall within the range established by formula (I).

[0015] In certain respects, the at least five fragrances included in the high-performance fragrance composition are further defined by their intensity values. In particular, the at least five fragrances comprise: (i) at least two fragrance ingredients with an intensity value in the range of 40 to 60, wherein each of these fragrance ingredients is present in a dosage greater than 2% by weight of the high-performance fragrance composition, and (ii) at least three fragrance ingredients with an intensity value greater than 60, wherein each of these fragrance ingredients is present in a dosage greater than 1% by weight of the high-performance fragrance composition.

[0016] As used in this document, the terms “high-performance fragrance composition”, “fragrance composition”, “fragrance formulation”, “perfume composition”, “fragrance accord” or “perfume accord” refer to a composition comprising at least five fragrances, wherein the fragrance composition is intended to be used in a rinse-out conditioner application, i.e., to impart a pleasant odor to the conditioner or to mask an unpleasant odor from the conditioner.

[0017] As used in this document, the terms “perfume”, “fragrance”, “fragrance material” and “fragrance ingredient” are used interchangeably to designate the component in the high-performance fragrance composition that is capable of imparting or modifying the odor of hair or other substrates. A fragrance ingredient may encompass any perfume raw materials suitable for use in fragrances, including materials such as, for example, alcohols, aldehydes, ketones, esters, Petition 870250080574, dated 09 / 08 / 2025, p. 94 / 125 7 / 31 Ethers, acetates, nitriles, terpene hydrocarbons, nitrogenous or sulfurous heterocyclic compounds, and essential oils. Non-limiting examples of fragrance materials may also include pro-fragrances, such as acetal pro-fragrances, ketal pro-fragrances, ester pro-fragrances, hydrolyzable inorganic-organic pro-fragrances, and mixtures thereof. Fragrance materials can be released from pro-fragrances in various ways. For example, fragrance may be released as a result of simple hydrolysis, or by a change in an equilibrium reaction, or by a change in pH, or by enzymatic release. Individual fragrance ingredients are readily available from commercial sources such as International Flavor & Fragrances (New York, NY), Givaudan Fragrances Corp. (East Hanover, NJ), Symrise (Branchburg, NJ), and Firmenich (Princeton, NJ).

[0018] “Pure” or “pure oil” refers to a fragrance composition free from extraneous matter. A pure fragrance composition includes only fragrance ingredients and is not encapsulated and / or bound to other compounds that would cause a delay in the release of the fragrance ingredients.

[0019] As used in this document, a fragrance ingredient selected for use in a high-performance fragrance composition is defined as a fragrance ingredient that exhibits an adequate level of deposition on wet hair and a high level of retention for at least 10 hours on dry hair. In specific aspects, a fragrance ingredient selected for use in a high-performance fragrance composition exhibits at least 1% to 25% deposition on wet hair, for example, at least 1%, 5%, 7%, 10%, 12%, 15%, 17%, 20%, 22% or 25% deposition on wet hair. The level of deposition of a fragrance is determined by uniformly applying a rinse-out conditioning product, including the fragrance ingredient, to a hair sample and measuring it. Petition 870250080574, dated 08 / 09 / 2025, page 95 / 125 8 / 31 of the amount of fragrance deposited on the hair sample after rinsing the hair sample with water to remove residual product. Fragrance measurements are made by extracting the fragrance from the wet hair sample with solvent and comparing the amount of fragrance extracted, for example, determined by gas chromatography, with one or more control samples.

[0020] In addition to the appropriate level of deposition, a fragrance ingredient selected for use in a high-performance fragrance composition exhibits at least 60% retention in dry hair for at least 10 hours, for example, at least 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% or 100% retention in dry hair for at least 10 hours. The retention level of a fragrance is determined by uniformly applying a rinse-out conditioning product, including the fragrance ingredient, to a hair sample, measuring the amount of fragrance deposited in the hair sample after rinsing the hair sample with water to remove residual product, allowing the hair sample to dry, and after 10 hours, measuring the amount of fragrance retained in the dry hair sample.Fragrance measurements are taken as described above, and fragrance retention is determined in relation to the amount of fragrance deposited; for example, a 5% loss of fragrance after 10 hours indicates that 95% of the deposited fragrance was retained.

[0021] The fragrance ingredients with a combined analytical deposition value and retention value that fall within the range established by formula (I) are presented in Table 1. Notably, the fragrance ingredients listed in Table 1 are not considered base notes that perfumers typically select to provide long-lasting performance on dry hair.

[0022] In addition to meeting the criteria set forth in formula (I), at least two fragrance ingredients of the high-performance fragrance composition have an intensity value in the range of 40 to 60, and at least three fragrance ingredients of the high-performance fragrance composition have an intensity value greater than 60. As used in this document, the terms “fragrance intensity”, “perceived intensity”, “perceived fragrance intensity”, “perceived fragrance performance” or “perceived performance” are used interchangeably to refer to Petition 870250080574, dated 09 / 08 / 2025, p. 97 / 125 10 / 31 intensity of a fragrance as perceived by a consumer. These olfactory characteristics of a fragrance composition are typically evaluated under different conditions by panels of trained experts, capable of unequivocally differentiating the odor of a given fragrance composition in a first condition, for example, during or after dilution of a rinse-out conditioner containing said fragrance composition, or on a substrate wetted with the product, from the odor of the same fragrance product, but in a second condition, for example, after the product has dried on the substrate. Under these conditions, the difference is considered perceptible to the consumer, i.e., most consumers will perceive the change in odor from said first condition to said second condition.

[0023] For the purposes of this invention, fragrance intensity is classified on a scale ranging from 0 to 100, thus providing a fragrance intensity value or score. In specific aspects, fragrance intensity is determined in a dry phase, for example, after applying the fragrance to wet hair and subsequently drying the hair. In other aspects, fragrance intensity is determined 24 hours after drying. In still other aspects, fragrance intensity is determined on a substrate, for example, hair samples, at a dosage of 0.2% by weight in a rinse-out conditioning product. According to this classification, a fragrance intensity value of 4 would indicate that the fragrance on the substrate being evaluated produces a weak intensity, while an intensity value of 70 would indicate that the fragrance on the substrate generates a very strong smell.

[0024] Fragrance intensity indices can also be used to classify the intensity of fragrance in a fragrance composition or in a consumer product containing it (collectively referred to as a “sample”). The fragrance intensity index is the ratio Petition 870250080574, dated 08 / 09 / 2025, page 98 / 125 11 / 31 between (i) the sensory intensity score of a sample and (ii) the sensory intensity score of allyl amyl glycolate (AAG), as a standard. The sensory intensity score of AAG is scaled on a range of 0 to 100, assessed by a sensory panel when AAG is dissolved in an appropriate solvent (e.g., diethyl phthalate). The sample is also assessed by the same panel at the same concentration, preferably under the same conditions and in the same sensory evaluation study conducted on the same day. The fragrance intensity index is then calculated as: sensory intensity score of a sample / sensory intensity score of AAG. See, for example, US 2020 / 0046616 Al and US 9,162,085 B2.

[0025] The fragrance ingredients, standard, accords, fragrance compositions and rinse-out conditioning products described in this document can be evaluated as described above and can also be evaluated following well-known protocols in the art using different scales, which can be normalized to a scale of 0 to 100 to calculate fragrance intensity values.

[0026] According to the present invention, the fragrance composition includes at least two fragrance ingredients having, on a scale of 0 to 100, an intensity value in the range of 40 to 60. In certain aspects, the fragrance composition includes, more preferably, at least two, preferably three, or most preferably four fragrance ingredients with an intensity value in the range of 40 to 60. In other aspects, the fragrance composition includes at least two fragrance ingredients with an intensity value in the range of 40 to 60, wherein each of said fragrance ingredients is present in a dosage greater than 2% by weight of the fragrance composition. In certain aspects, the fragrance composition includes at least two fragrance ingredients with an intensity value in the range of 40 to 60, wherein each of the fragrance ingredients Petition 870250080574, dated 08 / 09 / 2025, page 99 / 125 12 / 31 is present in a dosage greater than 2% by weight, preferably 3% by weight, more preferably 4% by weight, or most preferably 5% by weight of the fragrance composition. In some aspects, the fragrance composition includes at least two, three, or four fragrance ingredients with an intensity value in the range of 40 to 60, wherein each of said fragrance ingredients is present in a dosage greater than 2% by weight, 3% by weight, 4% by weight, or 5% by weight of the fragrance composition. In other aspects, the fragrance composition includes at least two, three, or four fragrance ingredients with an intensity value in the range of 40 to 60, wherein each of said fragrance ingredients is present in a dosage not greater than 10% by weight, 9% by weight, 8% by weight, 7% by weight, 6% by weight, or 5% by weight of the fragrance composition.

[0027] The present invention further provides that the fragrance composition includes at least three fragrance ingredients with an intensity value greater than 60 on a scale of 0 to 100. In certain aspects, the fragrance composition includes, more preferably, at least three, preferably four, or most preferably five fragrance ingredients with an intensity value greater than 60. In other aspects, the fragrance composition includes at least three fragrance ingredients with an intensity value greater than 60, wherein each of the fragrance ingredients is present in a dosage greater than 1% by weight of the fragrance composition.In certain aspects, the fragrance composition includes at least three fragrance ingredients with an intensity value greater than 60, wherein each of the fragrance ingredients is present in a dosage greater than 1% by weight, preferably 2% by weight, more preferably 3% by weight or, even more preferably, 4% by weight of the fragrance composition. In specific aspects, the fragrance composition includes at least three, four or five fragrance ingredients with a value of... Petition 870250080574, dated 08 / 09 / 2025, pages 100 / 125 13 / 31 intensity greater than 60, wherein each of the fragrance ingredients is present in a dosage greater than 1% by weight, 2% by weight, 3% by weight or 4% by weight of the fragrance composition. In other respects, the fragrance composition includes at least three, four or five fragrance ingredients with an intensity value greater than 60, wherein each of said fragrance ingredients is present in a dosage not greater than 10% by weight, 9% by weight, 8% by weight, 7% by weight, 6% by weight or 5% by weight of the fragrance composition.

[0033] The fragrance composition of this invention can be used as a pure fragrance and / or encapsulated in a delivery system. There is a wide variety of encapsulation materials that allow the delivery of fragrances at various points in the cleaning or conditioning process. Suitable encapsulation materials include starches, oligosaccharides, cyclodextrins, polyethylenes, polyamides, polystyrenes, polyisoprenes, polycarbonates, polyesters, polyacrylates, vinyl polymers, polyurethanes, amorphous silica, precipitated silica, fumed silica, aluminosilicates such as zeolites and alumina, and mixtures thereof.

[0034] The fragrance composition of the present invention finds particular use in a rinse-out hair conditioner. Rinse-out hair conditioning products, including the high-performance fragrance composition of the invention, will also include a product base, which performs one or more specific actions, such as cleansing, softening and conditioning or the like. The components of the hair product base may include any suitable additive that produces the intended effect under the intended conditions of use of the hair care product. For example, the ingredients of the hair product base may be selected from agents Petition 870250080574, dated 08 / 09 / 2025, pages 111 / 125 24 / 31 hair conditioners, skin care agents, sun protection agents, and skin conditioning agents. A person skilled in the art will understand that the base ingredients of the hair product will be selected based on the intended use of the hair product. For example, a hair conditioning product may include one or more surfactants, silicones, chelating agents, colorants, pigments, or formaldehyde scavengers suitable for providing the desired benefit to the consumer.

[0035] The surfactants used may be of the anionic, non-ionic, zwitterionic, amphoteric or cationic type, or may comprise compatible mixtures of these types. The product may contain up to 0.01% to about 30%, alternatively from about 0.01% to about 20%, more alternatively from about 0.1% to about 10%, by weight of the product, of a surfactant.

[0036] Suitable silicones include Si-O moieties and may be selected from (a) non-functionalized siloxane polymers, (b) functionalized siloxane polymers and combinations thereof. The molecular weight of the organosilicone is normally indicated by reference to the viscosity of the material. In one aspect, organosilicones may have a viscosity of about 10 to about 2,000,000 centistokes at 25 °C. In another aspect, suitable organosilicones may have a viscosity of about 10 to about 800,000 centistokes at 25 °C.

[0037] Suitable organosilicones may be linear, branched, or cross-linked. In some examples, the organosilicone may be a cyclic silicone. The cyclic silicone may be a cyclomethicone of the formula [(CH3)2SiO]n, where n is an integer that may range from about 3 to about 7, or from about 5 to about 6.

[0038] In some examples, the organosilicone may include a functionalized siloxane polymer. Functionalized siloxane polymers may include one or more functional moieties selected from the amino group, Petition 870250080574, dated 08 / 09 / 2025, pages 112 / 125 25 / 31 starch, alkoxy, hydroxy, polyether, carboxy, hydride, mercapto, sulfate phosphate and / or quaternary ammonium moieties. These moieties may be directly attached to the siloxane structure via a divalent (i.e., “pendant”) alkylene radical or may form part of the structure. Suitable functionalized siloxane polymers include materials selected from the group consisting of aminosilicones, amidosilicones, silicone polyethers, silicone-urethane polymers, quaternary ABn silicones, amino ABn silicones and combinations thereof.

[0039] In some examples, the functionalized siloxane polymer may include a silicone polyether, also referred to as a “dimethicone copolyol”. In general, silicone polyethers include a polydimethylsiloxane structure with one or more polyoxyalkylene chains. The polyoxyalkylene moieties may be incorporated into the polymer as pendant chains or as end blocks. In some examples, the functionalized siloxane polymer may include an aminosilicone.

[0040] The product may contain less than about 5%, or from about 0.01% to about 3%, by weight of the product, of a chelating agent, such as citrates; nitrogen-containing aminocarboxylates without P, ​​such as EDDS, EDTA and DTPA; aminophosphonates, such as diethylenetriaminepentamethylenephosphonic acid and ethylenediaminetetramethylenephosphonic acid; nitrogen-free phosphonates, for example, HEDP; and nitrogen- or oxygen-containing chelating agents without P and without carboxylates.

[0041] The hair product may contain any fragrance composition described herein at a level of 0.01% to 20% by weight (for example, 0.02% to 10% by weight, 0.05% to 5% by weight, 0.05% to 2% by weight, 0.1% to 0.5% by weight), wherein the lower limit may be 0.01% by weight, 0.02% by weight, 0.05% by weight, 0.1% by weight, 0.2% by weight or 0.5% by weight, and the upper limit may be 20% by weight, 15% by weight Petition 870250080574, dated 08 / 09 / 2025, pages 113 / 125 26 / 31 by weight, 10% by weight, 8% by weight, 6% by weight, 5% by weight, 3% by weight, 2% by weight, 1% by weight, 0.8% by weight or 0.5% by weight. In certain aspects, the rinse-out hair conditioner includes between 0.5% by weight and 1.2% by weight of the high-performance fragrance composition.

[0042] As will be understood by a person skilled in the art, the fragrance ingredients that meet the criteria of formula (I) and the intensity values ​​set forth herein may vary depending on the product and / or the components of the product base in which the fragrance ingredients will be included.

[0043] All parts, percentages and proportions referred to in this document and in the claims are by weight, unless otherwise indicated.

[0044] The values ​​and dimensions disclosed in this document should not be understood as being strictly limited to the exact numerical values ​​mentioned. Instead, unless otherwise indicated, each of these values ​​is intended to mean both the stated value and a functionally equivalent range around that value. For example, a value disclosed as “50%” is intended to mean “approximately 50%” and includes, for example, 50±5%.

[0045] When a quantity, concentration, or other value or parameter is given as a range, preferred range, or a list of upper preferred values ​​and / or lower preferred values, this shall be understood as specifically revealing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether the ranges are separately revealed.

All publications cited in this document are incorporated by reference in their entirety. Example 1: Analytical measurement of fragrance recovery

[0048] Preparation of the internal standard solution. Ethyl tetradecanoate (0.1 g) was placed in a 100 mL flask and ethanol was added to prepare the ethyl tetradecanoate standard.

[0049] Preparation of standard solutions. A stock solution was prepared by weighing 10*m of pure perfume in a 100 mL bottle (“m” is the theoretical weight of the perfume deposited) and adding qs with ethanol. “m” was equal to the weight of the product applied to the hair (mg) x dosage of the fragrance in the product (%).

[0050] In addition, three standard solutions representing 10%, 5% and 2% recovery were prepared by adding, respectively, 1000 pL, 500 pL and 200 pL of the stock solution in 20 mL bottles, adding 200 pL of the internal standard and qs with ethanol.

[0051] Extraction of perfume from hair. A hair sample was placed in a 30 mL container. Ethanol (20 mL) and 200 µL of the internal standard (ethyl tetradecanoate) were added to the hair sample. Each Petition 870250080574, dated 08 / 09 / 2025, pages 115 / 125 The 28 / 31 container was sealed and placed in an ultrasonic bath for 30 minutes and subsequently transferred to a shaker plate for 30 minutes. After shaking, a 2 mL gas chromatography tube was filled with the extract. Standard solutions, along with three individual samples for each hair sample, were analyzed for fragrance deposition by injecting the sample into a GC-MS using a SIM acquisition method. Standard solutions were injected into the GC-MS using the same acquisition method.

[0052] Quantification. Fragrance recovery was determined by quantifying all perfumery ingredients using a calibration curve obtained from standard solutions. Example 2: Determining fragrance intensity

[0053] The ingredients were dosed at 0.2% in the shampoo and 0.2% in the conditioner. For this analysis, samples of synthetic hair were used.

[0054] Application protocol for hair samples. Hair samples were immersed in cold water for 2 minutes. Shampoo (2 g) was applied to the sample and the hair was rotated 10 times in a circular motion in one direction and then 10 times in the other direction. The hair sample was smoothed 5 times from top to bottom and then left to rest for 5 minutes. The sample was rinsed horizontally for 30 seconds and then 2 g of conditioner was applied. Once again, the sample was rotated 10 times in a circular motion in one direction and then 10 times in the other direction, smoothed 5 times from top to bottom, left to rest for 5 minutes and rinsed horizontally for 30 seconds. The hair sample was wrung out to remove excess water and hung to dry overnight.

[0055] Evaluation of hair samples. After drying for 24 hours, a trained panel of at least 15 people evaluated the intensity of the fragrance. Petition 870250080574, dated 08 / 09 / 2025, pages 116 / 125 29 / 31 in dry hair samples compared to Allyl Amyl Glycolate (AAG) as a reference, which was equal to 50 on the intensity scale of 0 to 100. Example 3: Protocol for evaluating fragrance performance

[0056] Application protocol for hair samples. A hair conditioner base was dosed with between 0.4% by weight and 1.4% by weight of a fragrance composition of the invention. A sample of natural hair (8 g) was wetted under a stream of water (25 °C, flow rate 2 L / min) for 1 minute. The hair sample was gently squeezed with two fingers to remove excess water. The hair sample was placed in a Petri dish on a scale and 2 g of conditioner were applied to the hair sample. The hair was lathered between the palms of the hands in a clockwise direction for 10 turns, followed by 10 counter-clockwise circular movements. The sample hair was detangled and placed in a Petri dish for 15 seconds to allow the fragrance in the conditioner to be absorbed by the hair.Holding the sample horizontally with both hands, it was rinsed under a stream of water (25 °C, flow rate 2 L / min) while slowly moving from side to side for 20 seconds. Using two fingers, the hair sample was gently squeezed to remove excess water.

[0057] Evaluation of hair samples. After drying for 24 hours, a panel of 15 untrained people evaluated the fragrance intensity in the dried hair samples. Example 4: Performance of a fragrance formulation including high-performance fragrance ingredients

[0058] To demonstrate the effect of the fragrance composition of the invention on improving performance in dry hair, several different fragrance compositions and comparative compositions were prepared (Table 3). Accord AA (a reference accord) contained two ingredients with an intensity >60 at a dosage >1% (i.e., CYCLAPROP and GAMMA). Petition 870250080574, dated 09 / 08 / 2025, pp. 117 / 125 30 / 31 DECALACTONE) and an ingredient with an intensity >40 at a dosage of 2% (i.e., CYCLAMAL), with additional basic ingredients that were maintained at a constant quantity in all accords (i.e., HEXENOL CIS-3, VERDOX, PHENOXYETHYL ISOBUTYRATE, ALLYL CYCLOHEXYL PROP, IONONE BETA EXTRA, HELIONAL, DAMASCENONE, KHARISMAL). Accords AC and AC' contained three or four ingredients with an intensity >60 at a dosage >1% (i.e., CYCLAPROP, GAMMA DECALACTONE, DAMASCENONE DELTA, AMYL CINN ALD COEUR) and two or three ingredients with an intensity >40 at a dosage >2% (i.e., CYCLAMAL, OXYPHENYLON, and LILIAL). Accords AE and AD did not meet the requirements regarding the number and / or dosage of fragrance ingredients required by the method of this invention.
