Compositions containing fragrance materials

Abstract

Compositions including fragrance materials with fruity notes, such as consumer products and / or fragrance compositions.

Description

Technical Field

[0001] This disclosure relates to compositions comprising fragrance materials having fruity aroma notes, such as consumer products and / or fragrance compositions. This disclosure also relates to methods for preparing and using such compositions. Background Technology

[0002] Consumer products infused with pleasant fragrances (such as cleaning products, soaps, detergents, fabric fresheners, antiperspirants, air fresheners, and high-quality fragrances) are always in high demand. Consumers generally prefer fragrance materials that are described as "fruity" or have a "fruity scent." Most fruity fragrance materials have ester functional groups. However, a significant drawback of most ester-based fruity fragrance materials is their relatively low vapor pressure. Low vapor pressure fragrance materials resist escaping from liquid consumer product compositions, thus reducing their likelihood of reaching the consumer's nose and providing a pleasant sensation. Therefore, there is a persistent demand for new fragrance materials that possess both a fruity scent and a relatively high vapor pressure.

[0003] Furthermore, in order to overcome the low vapor pressure while still imparting the desired fruity scent to consumer products, manufacturers have traditionally simply added more fruity fragrance materials containing esters to them. New fragrance materials that possess both fruity notes and relatively high vapor pressure would allow for lower dosage levels in consumer products, thus providing more sustainable consumer products that also deliver the desired fruity scent.

[0004] Therefore, there is a continued demand for novel fragrance materials with fruity notes that can be used in consumer products, compositions, and related methods. Summary of the Invention

[0022] Ester-containing fragrance materials with fruity notes :

[0023] Many of the compositions, products, and methods described herein include ester-containing fragrance materials with fruity notes. As described in more detail below, such materials are believed to provide compositions and products with a pleasant aroma, while also possessing certain advantageous properties such as a relatively high vapor pressure that provides a more pronounced aromatic bloom, which helps to save on raw material costs and reduce the carbon footprint.

[0024] As described herein, the ester-containing compounds specifically detailed are referred to as fragrance materials. As further described in the Examples section below, certain ester-containing compounds of interest (such as, but not limited to, 3-methoxybutyl acetate, hexyl methacrylate, diethyl isobutylmalonate, diethyl cyclobutane-1,1-dicarboxylate, and methyl 4-methoxybicyclo[2,2,2]octane-1-carboxylate) are characterized by fruity notes, as well as certain other desirable properties, including relatively high vapor pressures (when compared to other ester-containing fragrance materials with fruity notes), which may make them desirable alternatives to traditional fragrance materials with fruity notes in consumer products. Table 1 below lists four of these fragrance materials of interest that have proven usable in this document.

[0025] Table 1 :

[0026]

[0027] The vapor pressure at 25°C is a theoretical value predicted by a physicochemical property model simulator from ACD / Labs. This vapor pressure model is widely accepted in industry and used by CAS / SciFinder. Calculate Physicochemical Properties | PhysChem Suite | ACD / Labs (acdlabs.com)

[0028] The predicted minimum vapor pressure of the fragrance materials (diethyl isobutylmalonate) listed in Table 1 is higher than 65% of the predicted vapor pressure of all known fruit ester fragrance raw materials. Therefore, all four listed fragrance materials have relatively high vapor pressures when compared to all known fruit ester PRMs. This prediction of relatively high vapor pressure results in a higher likelihood of reaching the consumer's nose and imparting a pleasant sensation, as will be further demonstrated using the topspace data in the Examples section of this document.

[0029] Consumer products

[0030] This disclosure relates to consumer products comprising ester-containing fragrance materials having a fruity aroma. Typically, the consumer product will also contain processing aids. Alternatively or additionally, the consumer product may contain fragrance materials supplied to a substrate.

[0031] Consumer products may take any suitable form. Preferably, consumer products are baby care products, beauty care products, fabric care products, home care products, household care products, feminine care products, health care products, food products, beverage products, high-quality fragrance products, or combinations thereof. The consumer products disclosed herein may be compositions, devices, or combinations thereof applicable to baby care products, beauty care products, fabric care products, home care products, household care products, feminine care products, health care products, food, beverages, and / or high-quality fragrance applications. For consumer health reasons, it may be preferred that the consumer product is not a tobacco-related product, such as cigarettes, electronic cigarettes, or products designed to produce a tobacco-like odor (such as aerosols).

[0032] Consumer products may preferably be fabric care products and / or home care products, wherein home care products are selected from the group consisting of hard surface cleaners, dish care products, air care products, or combinations thereof. Consumer products may be cleaning and / or treatment products.

[0033] Consumer products may take any suitable form or combination of forms. For example, consumer products may include forms selected from: liquid compositions, granular compositions, aqueous colloids, single-compartment pouches, multi-compartment pouches, soluble sheets, lozenges or beads, fibrous articles, tablets, rods, strips, sheets, sprays, foams / mousse, nonwoven sheets, dispensing devices, creams, absorbent articles, pastes, adhesives, adhesive patches, or mixtures thereof. Consumer products may be compositions, such as liquid compositions, contained in containers, dispensing devices, or other suitable articles of manufacture.

[0034] The consumer product may contain a first fragrance material, wherein the fragrance material is present in an amount of at least 0.0003% by weight of the consumer product; and a processing aid.

[0035] Consumer products may contain at least 0.0003%, or at least 0.0005%, or at least 0.001%, or at least 0.01%, or at least 0.05%, or at least 0.5%, or at least 0.8%, or at least 1.0%, or at least 2.0%, or at least 5.0%, or at least 10.0% of a first fragrance material (e.g., an ester-containing fragrance material with a fruity scent) by weight of the consumer product. Consumer products containing first fragrance materials in this range are typically laundry products, detergents, and other cleaning products containing surfactants. For consumer products containing a large amount of fragrance (such as high-quality fragrance products, fragrance enhancers, activated air fresheners, and volatile composition dispensers (activated or unactivated)), such consumer products may preferably contain a first fragrance material (e.g., an ester-containing fragrance material with a fruity scent) in an amount between about 0.0003% and about 20.0% by weight of the consumer product. Preferably, a minimum amount of fragrance material is used to deliver the desired olfactory performance.

[0036] In some embodiments, the consumer product may contain a first fragrance material (e.g., an ester-containing fragrance material with a fruity aroma) in an amount of up to about 99%, or up to about 50%, or up to about 25%, or up to about 10%, or up to about 5%, or up to about 1% by weight of the consumer product. Preferably, a maximum or limited amount of the first fragrance material is present to include other auxiliaries or fragrance materials.

[0037] Consumer products may contain a first fragrance material (e.g., an ester-containing fragrance material with a fruity aroma) in an amount of about 0.01% to about 99%, or about 0.1% to about 50%, or about 0.5% to about 10%, or about 1% to about 5% by weight of the consumer product.

[0038] Consumer products may contain a first fragrance material (e.g., an esterified fragrance material with a fruity aroma) and a second fragrance material selected from the group consisting of any fragrance material suitable for the intended product or end use, wherein the total fragrance material consists of at least 10%, or at least 20%, or at least 30%, or at least 40%, or at least 50%, or at least 60%, or at least 70%, or at least 80%, or at least 90%, or at least 95% biodegradable material. The term "biodegradable" is defined herein as the chemical dissolution, disintegration, or digestion of a biodegradable fragrance by bacteria or other biological means at a rate greater than 50%, according to the OECD 301 C test method, which defines the biodegradability of the material. In this test, the biodegradable fragrance is suspended in a phosphate buffer containing activated sludge inoculum, and oxygen consumption and / or carbon dioxide formation are measured by an electrolytic respiration meter. The test material is the sole carbon and energy source, and under aerobic conditions, microorganisms metabolize organic matter, producing CO2 as the final product.

[0039] For example, a consumer product may include: a first fragrance material, which is an ester-containing fragrance material having a fruity aroma; an optional second fragrance material selected from the group detailed in Table 2 herein, and mixtures thereof; and a processing aid; wherein, if present, the weight ratio of the first fragrance material to the second fragrance material is from 100:0 to 1:99.

[0040] The weight ratio of the first fragrance material (e.g., an ester-containing fragrance material with a fruity aroma) to the second fragrance material selected from the groups detailed in Table 2 herein and mixtures thereof may be 100:0 to 1:99, or 100:0 to 25:75, or 100:0 to 50:50, or 100:0 to 51:49, or 100:0 to 75:25, or 100:0 to 90:10, or 100:0 to 95:5, or 100:0 to 99:1.

[0041] It is preferable to formulate only one or more of the materials disclosed in this invention as listed in Table 1, and to omit other fragrance materials (e.g., the fragrance materials listed in Table 2). For example, consumer products may be substantially free of a second fragrance material, such as the fragrance materials listed in Table 2. Specifically, consumer products may contain ester-containing fragrance materials with fruity notes as detailed in Table 1, and substantially free of fragrance materials as detailed in Table 2.

[0042] The first fragrance material may be present in the consumer product as a free oil, or it may be part of a fragrance delivery system. For example, a fruity fragrance material detailed herein may be encapsulated in or otherwise associated with delivery particles (e.g., embedded within delivery particles). For example, a fruity fragrance material may be in the core of a core-shell delivery particle. The fruity fragrance material may be covalently or ionicly bonded, preferably covalently bonded to a carrier material, thereby forming a pre-fragrance material that releases the fragrance material when the bond breaks, such as by exposure to water or light. Thus, the fragrance material (e.g., the fragrance materials in Table 1) may be part of a fragrance delivery system, wherein the fragrance delivery system is a delivery particle, a pre-fragrance material, or a combination thereof.

[0043] As described above, consumer products contain processing aids. Processing aid materials may provide beneficial effects in the intended end use of the composition, or they may be processing aids and / or stabilizing agents. The exact nature of the processing aid and its incorporation level will depend on the physical form of the composition and the nature of the operation in which it is used. Those skilled in the art will be able to select the appropriate materials and levels for a given product or application.

[0044] Suitable processing aids may include antioxidants, surfactants, conditioning agents, deposition aids, rheology modifiers or structural agents, bleaching systems, stabilizers, detergent builders, chelating agents, dye transfer inhibitors, dispersants, enzymes, enzyme stabilizers, catalytic metal complexes, polymer dispersants, clay and dirt removers / anti-redeposition agents, brighteners, defoamers, siloxanes, toners, cosmetic dyes, fragrance additives, fragrance delivery systems, structural elasticizers, carriers, water-soluble growth promoters, processing aids, anti-agglomeration agents, coatings, formaldehyde removers, pigments, and mixtures thereof.

[0045] Processing aids may include a carrier. Such carriers can be hydrophilic (e.g., water) or hydrophobic (e.g., oil). The fruit-scented fragrance materials described in this invention are relatively hydrophobic and can be readily coupled to a hydrophobic carrier. Carriers particularly useful in consumer products include, but are not limited to, isopropyl myristate (IPM) and Neobee... ® Caprylic / capric triglyceride, dipropylene glycol, propylene glycol monomethyl ether (DPM), tripropylene glycol monomethyl ester (TPM), triethyl citrate (TEC), or mixtures thereof. Therefore, the consumer product may contain a carrier, wherein the carrier is preferably IPM, DPM, or mixtures thereof. Preferably, the carrier comprises isopropyl myristate.

[0046] Isopropyl myristate and other hydrophobic carriers can be particularly useful when fruity fragrance materials are encapsulated in certain core-shell delivery particles (such as those with acrylate or chitosan shells). The core of the delivery particle may contain isopropyl myristate and the fruity fragrance material.

[0047] Fragrance composition

[0048] This disclosure also relates to fragrance compositions. Such compositions typically comprise a mixture of fragrance ingredients. The fragrance compositions of this disclosure may be in the form of premixes or intermediate compositions that are combined with other materials to prepare a final product, such as a consumer product.

[0049] For example, the fragrance composition may take the form of a fragrance composition that is a mixture of fragrance materials, such as a fragrance blend that can be formulated into a consumer product.

[0050] The fragrance composition may comprise a first fragrance material and a second fragrance material different from the first fragrance material, wherein the first fragrance material is the fragrance material detailed in Table 1, and wherein the first fragrance material is present in an amount of at least 1% by weight of the fragrance composition.

[0051] The first fragrance material may be present in an amount of at least 0.005%, or at least 0.05%, or even 0.1% by weight of the fragrance composition. The first fragrance material may be present in an amount of about 0.005% to about 20%, or about 0.05% to about 10%, or about 0.005% to about 3%, or about 0.1% to about 1.5% by weight of the fragrance composition. The first fragrance material may be present in an amount of at least 1%, or at least 2%, or at least 5%, or even at least 10%, or even at least 20% by weight of the fragrance composition. The first fragrance material may be present in an amount of 1% to about 99%, or 1% to about 50%, or about 1% to about 25%, or about 1% to about 10%, or about 1% to about 5% by weight of the fragrance composition.

[0052] The second fragrance material can be freely selected from any group of fragrance materials suitable for the intended product or end use (e.g., one or more fragrance materials detailed in Table 2). As used herein, the term "fragrance ingredient" (or "PRM") refers to a compound having a molecular weight of at least about 100 g / mol and which can be used alone or together with other fragrance ingredients to impart odor, aroma, flavor, or fragrance. Typical PRMs particularly include aromatic and / or aliphatic alcohols, ketones, aldehydes, esters, ethers, carboxylic acids, nitriles, nitrites, and alkenes, such as terpenes and alkynes. A list of common PRMs can be found in various references, such as "Perfume and Flavor Chemicals," Volumes I and II; Steffen Arctander Allured Pub. Co. (1994) and "Perfumes: Art, Science and Technology," Miller, PM and Lamparsky, D., Blackie Academic and Professional (1994).

[0053] As a non-limiting illustrative example, suitable second fragrance materials are provided in Table 2 below. The second fragrance materials may be selected from the groups or combinations thereof provided in Table 2.

[0060] The weight ratio of the fragrance material in Table 1 to its counterpart (e.g., the fragrance materials listed in Table 2) can be particularly preferred. For example, the weight ratio of the fragrance material in Table 1 with a fruity aroma to the second fragrance material can be 100:0 to 1:99, or 100:0 to 25:75, or 100:0 to 50:50, or 100:0 to 51:49, or 100:0 to 75:25, or 100:0 to 90:10, or 100:0 to 95:5, or 100:0 to 99:1.

[0061] To provide a complete and desired olfactory experience, the fragrance composition may contain three or more fragrance materials. The fragrance composition may also contain a third fragrance material. The fragrance composition may contain two to fifty fragrance materials, or two to thirty fragrance materials. For simplicity and ease of manufacture, it may be desirable to limit the number of components in the fragrance composition. For example, the fragrance composition may contain two to twenty, or to fifteen, or to ten fragrance materials.

[0062] The fragrance composition may also include a carrier, preferably isopropyl myristate (IPM) or Neobee. ® The carriers of caprylic / capric triglycerides, dipropylene glycol, propylene glycol monomethyl ether (DPM), tripropylene glycol monomethyl ester (TPM), triethyl citrate (TEC), or mixtures thereof, more preferably the carriers comprising isopropyl myristate.

[0063] Other useful carriers can be solvents or emulsifiers, such as nonionic surfactants, which can help incorporate the fragrance composition into the final product form. The fragrance composition can be in the form of an emulsion, preferably an oil-in-water emulsion.

[0064] The fragrance compositions disclosed herein can be incorporated into consumer products, as described in more detail above.

[0109] Test methods

[0110] It should be understood that the test methods disclosed in the Test Methods section of this application should be used to determine the corresponding parameter values ​​of the subject matter claimed by the applicant as claimed and described herein.

[0111] Spice headspace method

[0112] Spice topspace data for various materials were collected using the methods described below.

[0113] The partition coefficient was calculated by determining the amount of PRM in the headspace above a solution of known concentration using GC / FID-MS (Agilent 7890 and 5977A MSD) equipped with a thermal desorption unit (Gerstel MPS2) and a dynamic headspace sampler (Gerstel DHS). This technique allows for automated headspace collection using a MultiPurpose Sampler (MPS). The PRM of interest was prepared at a known concentration in isopropyl myristate (IPM) or propylene glycol monomethyl ether (DPM), and 1 mL was pipetted into a 20 mL headspace vial.

[0114] DHS conditions: The sample was tempered in the unit at 30°C. A 10 mL / min helium flow purges the 20 mL headspace containing the analyte above the sample onto an adsorbent tube (TDU) containing 25 mg TenaxTA 35 / 60 (Restek catalog number 25701).

[0115] TDU conditions: The adsorbent tube was desorbed using a programmed procedure, starting with solvent discharge at 30°C for 2 minutes, then ramping up to 270°C at 720°C / min and holding for 8 minutes. The analyte was refocused onto the glass bead liner at -60°C and then desorbed to 270°C at a rate of 12°C / s onto the GC column.

[0116] GC / MS conditions: A 30m × 250μm × 0.25μm Agilent 122-5532UI column was used at a flow rate of 1.5 mL / min. A temperature program from 50°C to 280°C, holding for 2 minutes, and a ramp rate of 12°C / min were suitable. Scan parameters with solvent delay at DPM or SIM mode MSD parameters were applied to achieve appropriate detection.

[0117] Analytical standards were available from AK Scientific, Inc., Union City, CA 94587, USA. Stock solutions were prepared at approximately 0.5 g / L. The stock solutions were then diluted to 4 to 5 concentrations in the range of approximately 0.05 g / L to 0.00005 g / L. These standard solutions were then analyzed by GC / MS. This analysis was performed using the same TDU desorption and GC / MS conditions described above, where 1 μL of liquid was injected onto the TDU tube instead of being collected by DHS. The injection volume on the column and the area response of the target m / z were used to create a calibration curve with a linear fit.

[0118] The quantification of the headspace was performed using the PRM target m / z area response of the flavor components and the linear equation of the calibration curve.

[0119] Example

[0120] The embodiments provided below are intended to be illustrative in nature and are not intended to be limiting.

[0121] Example 1. Top Space Data

[0122] Headspace data for the flavors of 3-methoxybutyl acetate, hexyl methacrylate, diethyl isobutylmalonate, and methyl 4-methoxybicyclo[2,2,2]octane-1-carboxylate in isopropyl myristate (IPM) were collected using the headspace method described in the Testing Methods section above. Headspace data for the flavors of ethyl berry ester (diethyl 1,4-cyclohexanedicarboxylate, CAS No. 72903-27-6) and neopentyl ester (propionic acid, 3a,4,5,6,7,7aa-hexahydro-4,7-methylene-1H-inden-6-yl-2,2-dimethyl ester; CAS No. 68039-44-1) in isopropyl myristate (IPM) were also collected using the headspace method described in the Testing Methods section above. For all flavor headspace data, the average value was recorded after three replicate runs.

[0123] The flavor head space data for 3-methoxybutyl acetate, hexyl methacrylate, diethyl isobutylmalonate, and methyl 4-methoxybicyclo[2,2,2]octyl-1-carboxylate in isopropyl myristate (IPM) were compared with those for ethyl berry acetate and neopentyl ester in isopropyl myristate (IPM). The flavor head space ratios are shown in Table 4 below. As an example, the ratio of 3-methoxybutyl acetate to ethyl berry acetate was compared as follows:

[0124] HSR=HS 目标 / HS 参考 = 126.4

[0125] Where HSR is the headspace ratio, HS 目标 It is the top space of 3-methoxybutyl acetate, and HS 参考 It is the top space of berry ethyl ester.

[0126] Table 4 :

[0127]

[0128] Berry ethyl acetate and neopentyl acetate were chosen for comparison because they are popular fruity esters and were predicted to have lower vapor pressures than our PRM. Therefore, actual test data confirmed what the model data predicted: 3-methoxybutyl acetate, hexyl methacrylate, diethyl isobutylmalonate, diethyl cyclobutane-1,1-dicarboxylate, and methyl 4-methoxybicyclo[2,2,2]octane-1-carboxylate are more likely to be perceived at lower levels in consumer products, or at the same level but with greater intensity, compared to most other flavoring materials with fruity notes.
