PERFUME SYSTEMS
The present application relates to perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or such perfume delivery systems, as well as processes for making and using such perfume raw materials, perfume delivery systems and consumer products. Such perfume raw materials and compositions, including the delivery systems, disclosed herein expand the perfume communities' options as such perfume raw materials can provide variations on character and such compositions can provide desired odor profiles.
The present application relates to perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or perfume delivery systems, as well as processes for making and using such perfume raw materials, perfume delivery systems and consumer products.
BACKGROUND OF THE INVENTIONConsumer products may comprise one or more perfumes, and/or perfume delivery systems that can mask an undesirable odor and/or provide a desired scent and/or experience to a product and/or a situs that is contacted with such a product. While current perfumes, and perfume delivery systems provide desirable experiences and/or fragrances, consumers continue to seek products that contain sensates, such as cooling or have scents that may be longer lasting and that are tailored to their individual desires (see for example USPA 2007/0275866 A1 and USPA 2008/0305977 A1)—unfortunately the pool of perfume raw materials and perfume delivery systems that is available is still too limited to completely meet the desired needs.
Applicants believe that the perfume raw materials and perfumes, including the delivery systems, disclosed herein expand the options, as such sensates and/or perfume raw materials can provide variations on character and such and/or perfumes can provide desired sensations and/or odor profiles. In certain aspects, such and/or perfume raw materials and/or perfume delivery systems comprising such and/or perfume raw materials may provide variations on character, sensation and/or odor profiles that are better than expected as measured by parameters such as headspace analysis (employed to determine perfume delivery system perfume leakage and/or perfume delivery efficiency), C log P, boiling point and/or odor detection threshold.

Certain perfume delivery systems, methods of making certain perfume delivery systems and the uses of such perfume delivery systems are disclosed in USPA 2007/0275866 A1. Such perfume delivery systems include:
- I. Polymer Assisted Delivery (PAD): This perfume delivery technology uses polymeric materials to deliver perfume materials. Classical coacervation, water soluble or partly soluble to insoluble charged or neutral polymers, liquid crystals, hot melts, hydrogels, perfumed plastics, microcapsules, nano- and micro-latexes, polymeric film formers, and polymeric absorbents, polymeric adsorbents, etc. are some examples. PAD includes but is not limited to:
a.) Matrix Systems: The fragrance is dissolved or dispersed in a polymer matrix or particle. Perfumes, for example, may be 1) dispersed into the polymer prior to formulating into the product or 2) added separately from the polymer during or after formulation of the product. Diffusion of perfume from the polymer is a common trigger that allows or increases the rate of perfume release from a polymeric matrix system that is deposited or applied to the desired surface (situs), although many other triggers are know that may control perfume release. Absorption and/or adsorption into or onto polymeric particles, films, solutions, and the like are aspects of this technology. Nano- or micro-particles composed of organic materials (e.g., latexes) are examples. Suitable particles include a wide range of materials including, but not limited to polyacetal, polyacrylate, polyacrylic, polyacrylonitrile, polyamide, polyaryletherketone, polybutadiene, polybutylene, polybutylene terephthalate, polychloroprene, poly ethylene, polyethylene terephthalate, polycyclohexylene dimethylene terephthalate, polycarbonate, polychloroprene, polyhydroxyalkanoate, polyketone, polyester, polyethylene, polyetherimide, polyethersulfone, polyethylenechlorinates, polyimide, polyisoprene, polylactic acid, polymethylpentene, polyphenylene oxide, polyphenylene sulfide, polyphthalamide, polypropylene, polystyrene, polysulfone, polyvinyl acetate, polyvinyl chloride, as well as polymers or copolymers based on acrylonitrile-butadiene, cellulose acetate, ethylene-vinyl acetate, ethylene vinyl alcohol, styrene-butadiene, vinyl acetate-ethylene, and mixtures thereof.
“Standard” systems refer to those that are “pre-loaded” with the intent of keeping the pre-loaded perfume associated with the polymer until the moment or moments of perfume release. Such polymers may also suppress the neat product odor and provide a bloom and/or longevity benefit depending on the rate of perfume release. One challenge with such systems is to achieve the ideal balance between 1) in-product stability (keeping perfume inside carrier until you need it) and 2) timely release (during use or from dry situs). Achieving such stability is particularly important during in-product storage and product aging. This challenge is particularly apparent for aqueous-based, surfactant-containing products, such as heavy duty liquid laundry detergents. Many “Standard” matrix systems available effectively become “Equilibrium” systems when formulated into aqueous-based products. One may select an “Equilibrium” system or a Reservoir system, which has acceptable in-product diffusion stability and available triggers for release (e.g., friction). “Equilibrium” systems are those in which the perfume and polymer may be added separately to the product, and the equilibrium interaction between perfume and polymer leads to a benefit at one or more consumer touch points (versus a free perfume control that has no polymer-assisted delivery technology). The polymer may also be pre-loaded with perfume; however, part or all of the perfume may diffuse during in-product storage reaching an equilibrium that includes having desired perfume raw materials (PRMs) associated with the polymer. The polymer then carries the perfume to the surface, and release is typically via perfume diffusion. The use of such equilibrium system polymers has the potential to decrease the neat product odor intensity of the neat product (usually more so in the case of pre-loaded standard system). Deposition of such polymers may serve to “flatten” the release profile and provide increased longevity. As indicated above, such longevity would be achieved by suppressing the initial intensity and may enable the formulator to use more high impact or low odor detection threshold (ODT) or low Kovats Index (KI) PRMs to achieve FMOT benefits without initial intensity that is too strong or distorted. It is important that perfume release occurs within the time frame of the application to impact the desired consumer touch point or touch points. Suitable micro-particles and micro-latexes as well as methods of making same may be found in USPA 2005/0003980 A1. Matrix systems also include hot melt adhesives and perfume plastics. In addition, hydrophobically modified polysaccharides may be formulated into the perfumed product to increase perfume deposition and/or modify perfume release. All such matrix systems, including for example polysaccarides and nanolatexes may be combined with other PDTs, including other PAD systems such as PAD reservoir systems in the form of a perfume microcapsule (PMC). Polymer Assisted Delivery (PAD) matrix systems may include those described in US Patent Applications 2004/0110648 A1.
Silicones are also examples of polymers that may be used as PDT, and can provide perfume benefits in a manner similar to the polymer-assisted delivery “matrix system”. Such a PDT is referred to as silicone-assisted delivery (SAD). One may pre-load silicones with perfume, or use them as an equilibrium system as described for PAD. Functionalized silicones may also be used. Examples of silicones include polydimethylsiloxane and polyalkyldimethylsiloxanes. Other examples include those with amine functionality, which may be used to provide benefits associated with amine-assisted delivery (AAD) and/or polymer-assisted delivery (PAD) and/or amine-reaction products (ARP).
-
- b.) Reservoir Systems: Reservoir systems are also known as a core-shell type technology, or one in which the fragrance is surrounded by a perfume release controlling membrane, which may serve as a protective shell. The material inside the microcapsule is referred to as the core, internal phase, or fill, whereas the wall is sometimes called a shell, coating, or membrane. Microparticles or pressure sensitive capsules or microcapsules are examples of this technology. Microcapsules of the current invention are formed by a variety of procedures that include, but are not limited to, coating, extrusion, spray-drying, interfacial, in-situ and matrix polymerization. The possible shell materials vary widely in their stability toward water. Among the most stable are polyoxymethyleneurea (PMU)-based materials, which may hold certain PRMs for even long periods of time in aqueous solution (or product). Such systems include but are not limited to urea-formaldehyde and/or melamine-formaldehyde. Stable shell materials include polyacrylate-based materials obtained as reaction product of an oil soluble or dispersible amine with a multifunctional acrylate or methacrylate monomer or oligomer, an oil soluble acid and an initiator, in presence of an anionic emulsifier comprising a water soluble or water dispersible acrylic acid alkyl acid copolymer, an alkali or alkali salt. Gelatin-based microcapsules may be prepared so that they dissolve quickly or slowly in water, depending for example on the degree of cross-linking. Many other capsule wall materials are available and vary in the degree of perfume diffusion stability observed. Without wishing to be bound by theory, the rate of release of perfume from a capsule, for example, once deposited on a surface is typically in reverse order of in-product perfume diffusion stability. As such, urea-formaldehyde and melamine-formaldehyde microcapsules for example, typically require a release mechanism other than, or in addition to, diffusion for release, such as mechanical force (e.g., friction, pressure, shear stress) that serves to break the capsule and increase the rate of perfume (fragrance) release. Other triggers include melting, dissolution, hydrolysis or other chemical reaction, electromagnetic radiation, and the like. The use of pre-loaded microcapsules requires the proper ratio of in-product stability and in-use and/or on-surface (on-situs) release, as well as proper selection of PRMs. Microcapsules that are based on urea-formaldehyde and/or melamine-formaldehyde are relatively stable, especially in near neutral aqueous-based solutions. These materials may require a friction trigger which may not be applicable to all product applications. Other microcapsule materials (e.g., gelatin) may be unstable in aqueous-based products and may even provide reduced benefit (versus free perfume control) when in-product aged. Scratch and sniff technologies are yet another example of PAD.
- II. Molecule-Assisted Delivery (MAD): Non-polymer materials or molecules may also serve to improve the delivery of perfume. Without wishing to be bound by theory, perfume may non-covalently interact with organic materials, resulting in altered deposition and/or release. Non-limiting examples of such organic materials include but are not limited to hydrophobic materials such as organic oils, waxes, mineral oils, petrolatum, fatty acids or esters, sugars, surfactants, liposomes and even other perfume raw material (perfume oils), as well as natural oils, including body and/or other soils. Perfume fixatives are yet another example. In one aspect, non-polymeric materials or molecules have a C Log P greater than about 2. Molecule-Assisted Delivery (MAD) may also include those described in U.S. Pat. No. 7,119,060.
- III. Fiber-Assisted Delivery (FAD): The choice or use of a situs itself may serve to improve the delivery of perfume. In fact, the situs itself may be a perfume delivery technology. For example, different fabric types such as cotton or polyester will have different properties with respect to ability to attract and/or retain and/or release perfume. The amount of perfume deposited on or in fibers may be altered by the choice of fiber, and also by the history or treatment of the fiber, as well as by any fiber coatings or treatments. Fibers may be woven and non-woven as well as natural or synthetic. Natural fibers include those produced by plants, animals, and geological processes, and include but are not limited to cellulose materials such as cotton, linen, hemp jute, flax, ramie, and sisal, and fibers used to manufacture paper and cloth. Fiber-Assisted Delivery may consist of the use of wood fiber, such as thermomechanical pulp and bleached or unbleached kraft or sulfite pulps. Animal fibers consist largely of particular proteins, such as silk, sinew, catgut and hair (including wool). Polymer fibers based on synthetic chemicals include but are not limited to polyamide nylon, PET or PBT polyester, phenol-formaldehyde (PF), polyvinyl alcohol fiber (PVOH), polyvinyl chloride fiber (PVC), polyolefins (PP and PE), and acrylic polymers. All such fibers may be pre-loaded with a perfume, and then added to a product that may or may not contain free perfume and/or one or more perfume delivery technologies. In one aspect, the fibers may be added to a product prior to being loaded with a perfume, and then loaded with a perfume by adding a perfume that may diffuse into the fiber, to the product. Without wishing to be bound by theory, the perfume may absorb onto or be adsorbed into the fiber, for example, during product storage, and then be released at one or more moments of truth or consumer touch points.
- IV. Cyclodextrin Delivery System (CD): This technology approach uses a cyclic oligosaccharide or cyclodextrin to improve the delivery of perfume. Typically a perfume and cyclodextrin (CD) complex is formed. Such complexes may be preformed, formed in-situ, or formed on or in the situs. Without wishing to be bound by theory, loss of water may serve to shift the equilibrium toward the CD-Perfume complex, especially if other adjunct ingredients (e.g., surfactant) are not present at high concentration to compete with the perfume for the cyclodextrin cavity. A bloom benefit may be achieved if water exposure or an increase in moisture content occurs at a later time point. In addition, cyclodextrin allows the perfume formulator increased flexibility in selection of PRMs. Cyclodextrin may be pre-loaded with perfume or added separately from perfume to obtain the desired perfume stability, deposition or release benefit. Suitable CDs as well as methods of making same may be found in USPA 2005/0003980 A1.
- V. Starch Encapsulated Accord (SEA): The use of a starch encapsulated accord (SEA) technology allows one to modify the properties of the perfume, for example, by converting a liquid perfume into a solid by adding ingredients such as starch. The benefit includes increased perfume retention during product storage, especially under non-aqueous conditions. Upon exposure to moisture, a perfume bloom may be triggered. Benefits at other moments of truth may also be achieved because the starch allows the product formulator to select PRMs or PRM concentrations that normally cannot be used without the presence of SEA. Another technology example includes the use of other organic and inorganic materials, such as silica to convert perfume from liquid to solid. Suitable SEAs as well as methods of making same may be found in U.S. Pat. No. 6,458,754 B1.
- VI. Inorganic Carrier Delivery System (ZIC): This technology relates to the use of porous zeolites or other inorganic materials to deliver perfumes. Perfume-loaded zeolite may be used with or without adjunct ingredients used for example to coat the perfume-loaded zeolite (PLZ) to change its perfume release properties during product storage or during use or from the dry situs. Suitable zeolite and inorganic carriers as well as methods of making same may be found in USPA 2005/0003980 A1. Silica is another form of ZIC. Another example of a suitable inorganic carrier includes inorganic tubules, where the perfume or other active material is contained within the lumen of the nano- or micro-tubules. In one aspect, the perfume-loaded inorganic tubule (or Perfume-Loaded Tubule or PLT) is a mineral nano- or micro-tubule, such as halloysite or mixtures of halloysite with other inorganic materials, including other clays. The PLT technology may also comprise additional ingredients on the inside and/or outside of the tubule for the purpose of improving in-product diffusion stability, deposition on the desired situs or for controlling the release rate of the loaded perfume. Monomeric and/or polymeric materials, including starch encapsulation, may be used to coat, plug, cap, or otherwise encapsulate the PLT. Suitable PLT systems as well as methods of making same may be found in U.S. Pat. No. 5,651,976.

Test MethodsIt is understood that the test methods that are disclosed in the Test Methods Section of the present application should be used to determine the respective values of the parameters of Applicants' invention as such invention is described and claimed herein.
(1) C log PThe log P values of many perfume ingredients have been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, Calif., contains many, along with citations to the original literature. However, the log P values are most conveniently calculated by the “C LOG P” program, also available from Daylight CIS. This program also lists experimental log P values when they are available in the Pomona92 database. The “calculated log P” (C log P) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment approach is based on the chemical structure of each perfume ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding. The C log P values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental log P values in the selection of perfume ingredients which are useful in the present invention.
(2) Boiling PointBoiling point is measured by ASTM method D2887-04a, “Standard Test Method for Boiling Range Distribution of Petroleum Fractions by Gas Chromatography,” ASTM International.
(3) Headspace Ratio
-
- (a) Obtain a fragrance free consumer product formulation.
- (b) Obtain fragrance microcapsules whose water content has been adjusted to achieve a perfume content of 25 wt % in the aqueous slurry.
- (c) Prepare Sample A by adding 2.0 grams of the fragrance microcapsule aqueous slurry to 95 grams of the fragrance free consumer product formulation. Then add 3.0 grams of deionized water to balance the formulation to 100 grams. Age this formulation for 1 week at 40 degrees Centigrade.
- (d) Prepare Sample B by adding 0.50 grams of the neat fragrance to 95 grams of fragrance free consumer product formulation. Then add 4.5 grams of deionized water to balance the formulation to 100 grams. Age this formulation for 1 week at 40 degrees Centigrade.

Solid-Phase Micro-Extraction (SPME)-Gas Chromatography/Mass Spectrometry is used to measure the level of perfume raw materials in the headspace of products. 1.0 grams of the 1 week at 40 degrees Centigrade aged sample are placed into a clean 20 ml headspace vial and allowed to equilibrate for at least 2 hours at room temperature.
The samples are then analyzed using the MPS2-SMPE-GC-MS analysis system (GC-02001-0153, MSD-02001-0154, MPS2-02001-0155).
Apparatus:
- 1. 20 ml headspace vial
- 2. Timer.
- 3. Gas Chromatograph (GC): Agilent model 6890 with a CIS-4 injector (Gerstel, Mulheim, Germany) and MPS-2 Autosampler and TDU. For SPME analysis, we used the split/splitless injector (not the CIS-4 injector).

-
- 1. Transfer sample to proper sample tray and proceed with SPME-GC-MS analysis.
- 2. Start sequence of sample loading and analysis. In this step, the sample is allowed to equilibrate for at least two hours on the auto sampler tray, then sampled directly from the tray. The SPME fiber assembly is DVB/CAR/PDMS (50/30 um, 24 ga, 1 cm length). Sampling time is 5 minutes.
- 3. Injector temperature is at 260 C.
- 4. Then GC-MS analysis run is started. Desorption time is 5 minutes.
- 5. The following temperature program is used:
- i) an initial temperature of about 50° C. which is held for 3 minutes,
- ii) increase the initial temperature at a rate of about 6° C./min until a temperature of about 250° C. is reached, then 25° C./min to 275° C., hold at about 275° C. for 4.67 minute.
- 6. Perfume compounds are identified using the MS spectral libraries of John Wiley & Sons and the National Institute of Standards and Technology (NIST), purchased and licensed through Hewlett Packard.
- 7. Chromatographic peaks for specific ions are integrated using the Chemstation software obtained from Agilent Technologies, Inc., Wilmington, Del., USA.
- 8. The ratio for each PRM is calculated by dividing the peak area for the perfume raw material in Sample A by the peak area in Sample B.
- 9. Each ratio is then weighted by that perfume raw material's weight composition in the perfume.
- 10. The Headspace Ratio is calculated as the sum of the individual perfume raw material ratios obtained in step 9.

-
- The perfume leakage from capsules per individual Perfume Raw Material:
% perfume leakage=((Area Perfume Raw Material caps×Area Internal Standard Solution ref×Weight ref)/(Area Internal Standard Solution caps×Area Perfume Raw Material ref×Weight caps))×100
Determined using a gas chromatograph. The gas chromatograph is calibrated to determine the exact volume of material injected by the syringe, the precise split ratio, and the hydrocarbon response using a hydrocarbon standard of known concentration and chain length distribution. The air flow rate is accurately measured and, assuming the duration of human inhalation to last 12 seconds, the sampled volume is calculated. Since the precise concentration at the detector at any point in time is known, the mass per volume inhaled is known, and hence the concentration of material.
For example, to determine whether a material has a threshold below 50 parts per billion, solutions are delivered to the sniff port at the calculated concentration. A panelist sniffs the GC effluent and identifies the retention time when odor is noticed. The average among 6 panelists determines the threshold of notice ability. The necessary amount of analyte is injected into the column to achieve a 50 parts per billion concentration at the detector. Typical gas chromatograph parameters for determining odor detection thresholds are listed below:
-
- GC: 5890 Series II with FID detector, 7673 Autosampler
- Column: J&W Scientific DB-1
- Length: 30 meters, 0.25 millmeter inside diameter, 1 micrometer film thickness
- Method:
- split injection: 17/1 split ratio
- Autosampler: 1.13 microliters per injection
- Column flow: 1.10 milliLiters per minute
- Air Flow: 345 milliLiters per minute
- Inlet Temperature: 245 degrees Centigrade
- Detector Temperature: 285 degrees Centigrade
- Initial Temperature=50 degrees Centigrade, 5 degrees Centigrade per minute ramp rate, final temperature=280 degrees Centigrade, Final time=6 minutes
- Leading assumptions: 12 seconds per sniff, GC air adds to sample dilution
HEK-23 (human embryonic kidney) cells stably transfected with human TRPM8 were grown in 15 ml growth medium [high glucose DMEM (Dulbecco's Modification of Eagle's Medium) supplemented with 10% FBS (fetal bovine serum), 100 ug/ml Penicillin/streptomycin, 5 μg/ml blasticindin, and 100 μg/ml zeocin) in a 75 CM 2 flask for 3 days at 37° C. in a mammalian cell culture incubator set at 5% CO2. Cells were detached with addition of 2 ml of trypsin-EDTA buffer (GIBCO® 25200, Invitrogen) for about 2-3 min. Trypsin was inactivated by addition of 8 ml growth medium. Cells were transferred to a 50 ml tube and centrifuged at 850 rpm for 3 minutes to remove medium. After centrifugation, a pellet of cells was formed in the bottom of the tube separating them from the supernatant solution. The supernatant was discarded and the cell pellet was suspended in 1 ml of fresh growth medium to which 5 ul (12.5 ug) of Fluo-4 AM (Molecular Probes, Inc.) calcium indicator was added and incubated for 30 min with gentle shaking. (Fluo-4 is a fluorescent dye used for quantifying cellular Ca t concentrations in the 100 nM to 1 microM range.) At the end of 30 minutes, 45 ml of assay buffer [1×HBSS (Hank's Balanced Salt Solution), 20 mM HEPES (4-(2-Hydroxyethyl)-1-piperazineethanesulfonic acid)] was added to wash cells and the resulting mixture was then centrifuged at 850 rpm for 3 minutes to remove excess buffer and Fluo-4 AM calcium indicator. The pellet cells were re-suspended in 10 ml assay buffer and 90 ul aliquots (−50,000 cells) per well delivered to a 96-well assay plate containing 10 ul of test compounds (1 mM in assay buffer, final concentration 100 uM) or buffer control and incubated at room temperature for 30 minutes. After 30 minutes, plate is placed into a fluorometric imaging plate reader (FLIPR 384 from Molecular Devices) and basal fluorescence recorded (excitation wave length 488 nm and emission wave length 510 nm). The FLIPR assay is an accepted method for detecting changes in intracellular calcium concentration. Then 20 ul of 37.5 uM of the compounds of the invention were tested as TRPM8 agonist in the assay buffer (final concentration 6.25 uM) was added and fluorescence recorded. For determining the direct effect of test compounds on TRPM8, fluorescence was measured immediately after addition of each compound.
