[0002] SOLID FRAGRANCE COMPOSITION

[0003] Field of the Disclosure

[0004] The present disclosure relates to the field of perfumery. The present disclosure describes solid fragrance compositions useful for various applications in which fragrance delivery is desired, for example in cleaning applications, air freshening applications, and the like. In some aspects, the solid fragrance compositions of the present disclosure are water-soluble and may be solubilized at the point of use.

[0005] Background of the Disclosure

[0006] Fragrances play an important role in the perception of consumer product performance and thus they often determine the consumer's choice for a given product. In some consumer products, such as detergents, hard surface cleaners, air fresheners, and the like, fragrances as free oils are solubilized in liquids, typically in alcohol-based solutions or in water-based solutions with surfactants, in order to deliver a pleasant odor to the surrounding air, to fabrics, or to other various surfaces. In some cases, fragrances may be encapsulated in microcapsules and suspended in liquid solvent. However, the volume of the solvents used is often much larger than the volume of fragrance, leading to increased concerns around sustainability and consumer demand for environmental friendliness.

[0007] Solid fragrance formulations may be used to address the aforementioned concerns. For example, US Patent No. 10,912,853 (Blattner, et al.) describes a solid air freshener comprising a fragrance, surfactant, and a solidifier that can be diluted on site by a user to yield a liquid composition.

[0008] However, solid fragrance formulations are not without their own challenges. A major challenge for solid fragrance formulations, such as powder or tablet products, is the need for complex processing when fragrance oil is used. Applying liquid fragrance oils to a powder or tablet product is generally limited by production capabilities.

[0009] Often, the dose of fragrance oil needs to be below 1% to avoid stickiness or to maintain the ability to press the formulation into tablets. Higher amounts of Firmenich SA

[0010] fragrance oil can lead to leaking of the fragrance oil, incompatibility with tableting, or powder clumping.

[0011] Another challenge is the need for long lastingness and lingering bloom of the fragrance. Often, solid formulations incorporating fragrance oil do not provide adequate performance, i.e. , long lastingness and lingering bloom, that is desirable to the consumer.

[0012] Therefore, there is an ongoing need for solid fragrance compositions that can provide ease of manufacture, ease of use, and increased fragrance performance, such as improved long lastingness and lingering bloom.

[0013] Summary of the Disclosure

[0014] The following aspects of the present disclosure seek to address one or more of the problems described hereinabove.

[0015] In a first aspect, the present disclosure relates to a solid fragrance composition comprising a carrier and at least one perfumery raw material that is present as a solid under ambient conditions.

[0016] In a second aspect, the present disclosure relates to a method for imparting a fragrance to a solid composition that is otherwise fragrance-free, the method comprising adding at least one perfumery raw material that is a solid under ambient conditions.

[0017] In a third aspect, the present disclosure relates to a method for deodorizing and / or freshening a surface or an environment, the method comprising:

[0018] a) dissolving the solid fragrance composition described herein in water to form a liquid composition, typically transparent solution, and

[0020] Detailed Description

[0021] As used herein, the terms “a”, “an”, or “the” means “one or more” or “at least one” unless otherwise stated.

[0022] While compositions and methods are described in terms of “comprising,” “containing,” or “including” various components or steps, the compositions and methods can also “consist essentially of” or “consist of” the various components, substances and steps. As used herein the term “consisting essentially of” shall be construed to mean including the listed components, substances or steps and such additional components, substances or steps which do not materially affect the basic and novel properties of the composition or method. In some embodiments, a composition in accordance with embodiments of the present disclosure that “consists essentially of” the recited components or substances does not include any additional components or substances that alter the basic and novel properties of the composition.

[0023] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which this specification pertains.

[0024] It should be understood that any numerical range recited herein is intended to include all sub-ranges subsumed therein. For example, a range of “1 to 10” is intended to include all sub-ranges between and including the recited minimum value of 1 and the recited maximum value of 10; that is, having a minimum value equal to or greater than 1 and a maximum value of equal to or less than 10. Because the disclosed numerical ranges are continuous, they include every value between the minimum and maximum values. Unless expressly indicated otherwise, the various numerical ranges specified in this application are approximations.

[0025] As used herein, and unless otherwise indicated, the term “about” or “approximately” means an acceptable error for a particular value as determined by one of ordinary skill in the art, which depends in part on how the value is measured or determined. In certain embodiments, the term “about” or “approximately” means within 1, 2, 3, or Firmenich SA

[0027] Throughout the present disclosure, various publications may be incorporated by reference. Should the meaning of any language in such publications incorporated by reference conflict with the meaning of the language of the present disclosure, the meaning of the language of the present disclosure shall take precedence, unless otherwise indicated.

[0028] Throughout the present disclosure, various chemical names and structures may be recited. Unless otherwise stated, any stereoisomers, such as enantiomers, diastereomers, anomers, epimers, and the like; and geometric isomers, such as cis / trans or E / Z isomers, of the recited chemical name or structure are contemplated. As would be understood by those of ordinary skill in the art, stereoisomers may possess one stereocenter, giving rise to enantiomers, or more than one stereocenter, giving rise to diastereomers, each stereocenter having one of two different stereochemistries (i.e. , R or S). Enantiomers may be characterized by their ability to rotate oncoming plane-polarized light to the right, designated as dextrorotatory, “(+)” or “D”, or to the left, designated as levorotatory,

[0029]

[0030] or “L”.

[0031] Enantiomers may exist as racemic mixtures or scalemic mixtures. Geometric isomers refer to isomers in which the spatial relationship of atoms around a double bond are different, typically designated E or Z according to conventional understanding in the chemical art. Geometric isomers may also exist as mixtures of E and Z isomers. All of the aforementioned isomeric variations of the chemical names or structures recited herein are included.

[0032] In the first aspect, the present disclosure relates to a solid fragrance composition comprising a carrier and at least one perfumery raw material that is present as a solid under ambient conditions.

[0033] As used herein, the term “perfumery raw material” refers to a compound or mixture of perfuming ingredients used in perfuming formulations or compositions to impart a hedonic effect. In other words, to be considered as a perfuming ingredient, such a Firmenich SA

[0034] perfuming ingredient must be recognized by a person skilled in the art as being capable of imparting or modifying in an active or pleasant way the odor of a composition, and not just as having an odor.

[0035] As used herein, the term “perfuming ingredient” refers to a compound, the main purpose of which is to impart or modulate odor. In other words, to be considered as a perfuming ingredient, such ingredient must be recognized by a person skilled in the art as being capable of imparting or modifying in at least an active or pleasant way the odor of a composition, and not just as having an odor. For the purposes of this disclosure, perfume accords also include combinations of perfuming ingredients with substances that collectively improve, enhance or modify the delivery of the perfuming ingredients, such as pro-perfumes, emulsions or dispersions, as well as combinations that confer benefits other than modifying or conferring odor, such as longevity, eruption, malodor counteraction, antimicrobial effect, microbial stability, insect control.

[0036] The nature and type of perfuming ingredients do not warrant a more detailed description here, which in any case would not be exhaustive, as a person of ordinary skill in the art would be able to select them based on general knowledge and according to the intended use or application and the desired organoleptic effect. In general, these perfuming ingredients belong to chemical classes as varied as alcohols, aldehydes, ketones, esters, ethers, acetates, nitriles, terpenoids, nitrogenous or sulphurous heterocyclic compounds and essential oils, and can be of natural or synthetic origin. In any event, many of these ingredients are listed in references such as the works Perfume and Flavor Chemicals, 1969, Montclair, New Jersey, USA, or other works of a newer version or similar nature, by S. Arctander, and in patent literature abundant in the field of perfumery. It should also be understood that said ingredients can also be compounds known to release in a controlled manner various types of perfuming compounds.

[0037] As used herein, the phrase “solid under ambient conditions” means that the at least one perfumery raw material is in a solid or crystalline state at a temperature of from 15 °C to 30 °C at atmospheric pressure. Firmenich SA

[0038] The number of perfumery raw materials used in the composition of the present disclosure is not particularly limited. However, in an embodiment, the composition comprises at least 2, typically at least 3, more typically at least 4 perfumery raw materials that are present as solids under ambient conditions. In another embodiment, all perfumery raw materials are present as solids under ambient conditions.

[0039] An advantage of the solid fragrance composition of the present disclosure that results from the use of perfumery raw materials that are in the solid state under ambient conditions is ease of processing. The use of perfumery raw materials that are in the solid state under ambient conditions allows for fragrancing of solid formulations without the need for complex processes needed to combine liquid fragrance oil with solid materials, such as the need to encapsulate the fragrance oil in microcapsules or matrix materials. Therefore, in some embodiments, the at least one perfumery raw material is not encapsulated. In some embodiments, the at least one perfumery raw material is not absorbed or captured in a matrix material. In some embodiments, the composition is free of any perfumery raw material that is a liquid under ambient conditions.

[0040] The use of perfumery raw materials that are in the solid state under ambient conditions allows for fragrancing of solid formulations without the need for solidifying aids or extraneous ingredients to reduce clumping, such as starch, anti-caking agent, dessicant, urea, binding agent, porous particles, and the like. Thus, in some embodiments, the composition is free of starch, anti-caking agent, dessicant, urea, binding agent, or porous particles.

[0041] The phrase “free of” means that there is no external addition of the material modified by the phrase and that there is no detectable amount of the material that may be observed by analytical techniques known to those having ordinary skill in the art, such as, for example, gas or liquid chromatography, spectrophotometry, optical microscopy, and the like.

[0042] The at least one perfumery raw material that is present as a solid under ambient conditions is not particularly limited as long as it is solid or crystalline under ambient Firmenich SA

[0118] Table 1.

[0119]

[0120] Table 2.

[0121]

[0122] Example 2.

[0123] The effervescent tablets made according to Example 1 were each dissolved in 500 mL of water to simulate an all-purpose cleaner. The resulting solutions were tested in toilet booths equipped with sinks. The resulting solutions were each sprayed on the sink and then wiped off. A group of trained panelists were asked to rate the Firmenich SA

[0124] intensity of the fragrance on a scale of 0 to 10 right after spraying on the sink and 1 hour after the liquid was wiped off. All-purpose cleaner made from dissolving tablets according to Example 1 are designated (APC 1 , APC 2, and APC 3, in which APC 1 contained solid fragrance 1 , APC 2 contained solid fragrance 2, and APC 3 contained APC 3 contained solid fragrance 3. As reference, two commercial allpurpose cleaners (an all-purpose cleaner from Method Products Ltd. and a Sainsbury brand all-purpose cleaner) were used. Table 3 below summarizes the results of this test.

[0125] Table 3.

[0126]

[0127] Right after spraying in the sink, panelists reported that APC 1 remained strong and diffusive, with much higher intensity than Method or Sainsbury benchmarks.

[0128] One hour after wiping, panelists indicated that APC 3 provided the strongest intensity with gourmand vanilla notes, while APC 2 provided less intense, but perceivable fragrance having more of gourmand dry downs notes and less fruity ones. APC 1 was less perceivable, but a bit of orange blossom and mossy note was noticeable. The benchmarks (Method and Sainsbury) were gone and did not provide any noticeable odor.

[0129] As shown in the results of Table 3, the solid fragrance compositions according to some aspects of the present disclosure provided long-lasting performance compared to commercial benchmarks. Firmenich SA
