Description
PERFUME SYSTEMS
This is a division of co-pending Canadian Patent Application No. 2,799,582 filed on June 22, 2011, which is derived from national phase entry of International Patent Application PCT/US2011/041408, published as WO 2011/163337 on December 29, 2011.
FIELD OF INVENTION
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.
BACKGROUND OF THE INVENTION
Consumer products may comprise one or more perfumes and/or perfume delivery systems that can provide a desired scent to such product and/or a situs that is contacted with such a product and/or mask an undesirable odor. While current perfumes and perfume delivery systems provide desirable odors, consumers continue to seek products that have scents that may be longer lasting and that are tailored to their individual desires (see for example USPA
2007/0275866 Al and US Patent Application Serial No. 2008/0305977) ¨
unfortunately the pool of perfume raw materials and perfume delivery systems that is available is still too limited to completely meet the perfume community's needs. Thus, perfumers need an ever larger pool of perfume raw materials and perfume delivery systems.
Applicants believe that the perfume raw materials and compositions, including the delivery systems, disclosed herein expand the perfume community's options, as such perfume raw materials can provide variations on character and such compositions can provide desired odor profiles. In certain aspects, such perfume raw materials and/or perfume delivery systems comprising such perfume raw materials provide variations on character and/or odor profiles that are better than expected as measured by parameters such as headspace analysis which can be used to determine perfume delivery system perfume leakage and/or perfume delivery efficiency;
ClogP; boiling point and/or odor detection threshold.
la SUMMARY OF THE INVENTION
Certain exemplary embodiments provide a consumer product comprising:
a.) a perfume delivery system comprising based on total composition weight from 0.00001% to 99% of a perfume raw material, said perfume raw material is 3-((1R,5S)-6,6-dimethylbicyclo[3.1.1jhept-2-en-2-y1)-2,2-dirnethylpropanenitrile, said perfume delivery system being a polymer assisted delivery system, a molecule-assisted delivery system, a fiber-assisted delivery system, an amine assisted delivery system, a cyclodextrin delivery system, a starch encapsulated accord, an inorganic carrier delivery system, or a pro-perfume; and b.) an adjunct ingredient.

Perfume Delivery Systems 5 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 Al. Such perfume delivery systems include:
I. Polymer Assisted Delivery (PAD): This perfume delivery technology uses polymeric materials 10 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 15 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 (IU) 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 Al. 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 the following references: US Patent Applications 2004/0110648 Al; 2004/0092414 Al;
2004/0091445 Al and 2004/0087476 Al; and US Patents 6,531,444; 6,024,943;
6,042,792; 6,051,540; 4,540,721 and 4,973,422.
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. Suitable silicones as well as making same may be found in WO
2005/102261; USPA 20050124530A1; USPA 20050143282A1; and WO
2003/015736. Functionalized silicones may also be used as described in USPA
2006/003913 Al. 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).
Other such examples may be found in USP 4,911,852; USPA 2004/0058845 Al;
USPA 2004/0092425 Al and USPA 2005/0003980 Al.
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 emulsifier which can be anionic, non-ionic, cationic or zwitterionic 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. Perfume microcapsules (PMC) may include those described in the following references: US Patent Applications: 2003/0125222 Al; 2003/215417 Al;

2010/084480 A2.
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-coyalently 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 CLogP greater than about 2. Molecule-Assisted Delivery (MAD) may also include those described in USP 7,119,060 and USP
5,506,201.
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 haft 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. Amine Assisted Delivery (AAD): The amine-assisted delivery technology approach utilizes materials that contain an amine group to increase perfume deposition or modify perfume release during product use. There is no requirement in this approach to pre-complex or pre-react the perfume raw material(s) and amine prior to addition to the product. In one aspect, amine-containing AAD materials suitable for use herein may be non-aromatic; for example, polyalkylimine, such as polyethyleneimine (PEI), or polyvinylamine (PVAm), or aromatic, for 5 example, anthranilates. Such materials may also be polymeric or non-polymeric. In one aspect, such materials contain at least one primary amine. This technology will allow increased longevity and controlled release also of low ODT perfume notes (e.g., aldehydes, ketones, enones) via amine functionality, and delivery of other PRMs, without being bound by theory, via polymer-assisted delivery for polymeric amines. Without technology, volatile top notes can be 10 lost too quickly, leaving a higher ratio of middle and base notes to top notes. The use of a polymeric amine allows higher levels of top notes and other PRMS to be used to obtain freshness longevity without causing neat product odor to be more intense than desired, or allows top notes and other PRMs to be used more efficiently. In one aspect, AAD systems are effective at delivering PRMs at pH greater than about neutral. Without wishing to be bound by theory, 15 conditions in which more of the amines of the AAD system are deprotonated may result in an increased affinity of the deprotonated amines for PRMs such as aldehydes and ketones, including unsaturated ketones and enones such as damascone. In another aspect, polymeric amines are effective at delivering PRMs at pH less than about neutral. Without wishing to be bound by theory, conditions in which more of the amines of the AAD system are protonated may result in a 20 decreased affinity of the protonated amines for PRMs such as aldehydes and ketones, and a strong affinity of the polymer framework for a broad range of PRMs. In such an aspect, polymer-assisted delivery may be delivering more of the perfume benefit; such systems are a subspecies of AAD and may be referred to as Amine- Polymer-Assisted Delivery or APAD. In some cases when the APAD is employed in a composition that has a pH of less than seven, such APAD systems may also be considered Polymer-Assisted Delivery (PAD). In yet another aspect, AAD and PAD systems may interact with other materials, such as anionic surfactants or polymers to form coacervate and/or coacervates-like systems. ht another aspect, a material that contains a heteroatom other than nitrogen, for example sulfur, phosphorus or selenium, may be used as an alternative to amine compounds. In yet another aspect, the aforementioned alternative compounds can be used in combination with amine compounds. In yet another aspect, a single molecule may comprise an amine moiety and one or more of the alternative heteroatom moieties, for example, thiols, phosphines and selenols. Suitable AAD systems as well as methods of making same may be found in US Patent Applications 2005/0003980 Al;
2003/0199422 Al;
2003/0036489 Al; 2004/0220074 Al and USP 6,103,678.
V. 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 Al and Al and US Patents 5,552,378; 3,812,011; 4,317,881; 4,418,144 and 4,378,923.
VI. 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 USPA 2005/0003980 Al and USP 6,458,754 BI.
VII. 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 Al and US Patents 5,858,959; 6,245,732 BI; 6,048,830 and 4,539,135.
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 USP 5,651,976.
VIII. Pro-Perfume (PP): This technology refers to perfume technologies that result from the reaction of perfume materials with other substrates or chemicals to form materials that have a covalent bond between one or more PRMs and one or more carriers. The PRM is converted into a new material called a pro-PRM (i.e., pro-perfume), which then may release the original PRM
upon exposure to a trigger such as water or light. Pro-perfumes may provide enhanced perfume delivery properties such as increased perfume deposition, longevity, stability, retention, and the like. Pro-perfumes include those that are monomeric (non-polymeric) or polymeric, and may be pre-formed or may be formed in-situ under equilibrium conditions, such as those that may be present during in-product storage or on the wet or dry situs. Nonlimiting examples of pro-perfumes include Michael adducts (e.g., beta-amino ketones), aromatic or non-aromatic imines (Schiff bases), oxazolidines, beta-keto esters, and orthoesters. Another aspect includes compounds comprising one or more beta-oxy or beta-thio carbonyl moieties capable of releasing a PRM, for example, an alpha, beta-unsaturated ketone, aldehyde or carboxylic ester. The typical trigger for perfume release is exposure to water; although other triggers may include enzymes, heat, light, pH change, autoxidation, a shift of equilibrium, change in concentration or ionic strength and others. For aqueous-based products, light-triggered pro-perfumes are particularly suited. Such photo-pro-perfumes (PPPs) include but are not limited to those that release coumarin derivatives and perfumes and/or pro-perfumes upon being triggered.
The released pro-perfume may release one or more PRMs by means of any of the above mentioned triggers. In one aspect, the photo-pro-perfume releases a nitrogen-based pro-perfume when exposed to a light and/or moisture trigger. In another aspect, the nitrogen-based pro-perfume, released from the photo-pro-perfume, releases one or more PRMs selected, for example, from aldehydes, ketones (including enones) and alcohols. In still another aspect, the PPP releases a dihydroxy coumarin derivative. The light-triggered pro-perfume may also be an ester that releases a coumarin derivative and a perfume alcohol. In one aspect the pro-perfume is a dimethoxybenzoin derivative as described in USPA 2006/0020459 Al. In another aspect the pro-perfume is a 3', 5'-dimethoxybenzoin (DMB) derivative that releases an alcohol upon exposure to electromagnetic radiation. In yet another aspect, the pro-perfume releases one or more low ODT
PRMs, including tertiary alcohols such as linalool, tetrahydrolinalool, or dihydromyrcenol.

a.) Amine Reaction Product (ARP): For purposes of the present application, ARP
is a subclass or species of PP. One may also use "reactive" polymeric amines in which the amine functionality is pre-reacted with one or more PRMs to form an amine reaction product (ARP). Typically the reactive amines are primary and/or secondary amines, and may be part of a polymer or a monomer (non-polymer). Such ARPs may also be mixed with additional PRMs to provide benefits of polymer-assisted delivery and/or amine-assisted delivery. Nonlimiting examples of polymeric amines include polymers based on polyalkylirnines, such as polyethyleneimine (PEI), or polyvinylamine (PVAm). Nonlimiting examples of monomeric (non-polymeric) amines include hydroxyl amines, such as 2-aminoethanol and its alkyl substituted derivatives, and aromatic amines such as anthranilates. The ARPs may be premixed with perfume or added separately in leave-on or rinse-off applications. In another aspect, a material that contains a heteroatom other than nitrogen, for example oxygen, sulfur, phosphorus or selenium, may be used as an alternative to amine compounds.
In yet another aspect, the aforementioned alternative compounds can be used in combination with amine compounds. In yet another aspect, a single molecule may comprise an amine moiety and one or more of the alternative heteroatom moieties, for example, thiols, phosphines and selenols.

6. The injector liner is a special SPME liner (0.75 mm ID) from Supelco.
7. The Detector is a model 5973 Mass Selective Detector obtained from Agilent Technologies, Inc., Wilmington, DE, USA having a source temperature of about 230 C, and a MS Quad temperature of about 150 'C.
Analysis procedure:
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 5 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. Desportion time is 5 minutes.
10 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.
15 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 ChemstationTM software obtained from Agilent Technologies, Inc., Wilmington, DE, USA..
20 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.

Calculation - The perfume leakage from capsules per individual Perfume Raw Material:
% perfume leakage = ((Area Perfume Raw Material caps x Area Internal Standard Solution ref x Weight ref) / (Area Internal Standard Solution caps x Area Perfume Raw Material ref x Weight caps)) x 100 (5) Odor Detection Threshold (OD'1') is 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 determinewhether a material has a threshold below 50 parts per bullion, 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 noticeability. 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 HD detector, 7673 Autosampler Column: J&W Scientific DB-lrm Length: 30 meters, 0.25 millimeter 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 EXAMPLES

In another aspect, highly compacted a detergent that may comprise one or more PRMs selected from Table 1 PRMs 1, 2, 3, 4, 5, 6, 7, 8,9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86 and 87 and stereoisomers of such PRMs is disclosed.
Perfume Delivery Systems 5 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 Al. Such perfume delivery systems include:
I. Polymer Assisted Delivery (PAD): This perfume delivery technology uses polymeric materials 10 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 15 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 (IU) 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 Al. 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 the following references: US Patent Applications 2004/0110648 Al; 2004/0092414 Al;
2004/0091445 Al and 2004/0087476 Al; and US Patents 6,531,444; 6,024,943;
6,042,792; 6,051,540; 4,540,721 and 4,973,422.
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. Suitable silicones as well as making same may be found in WO
2005/102261; USPA 20050124530A1; USPA 20050143282A1; and WO
2003/015736. Functionalized silicones may also be used as described in USPA
2006/003913 Al. 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).
Other such examples may be found in USP 4,911,852; USPA 2004/0058845 Al;
USPA 2004/0092425 Al and USPA 2005/0003980 Al.
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 emulsifier which can be anionic, non-ionic, cationic or zwitterionic 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. Perfume microcapsules (PMC) may include those described in the following references: US Patent Applications: 2003/0125222 Al; 2003/215417 Al;
2003/216488 Al; 2003/158344 Al; 2003/165692 Al; 2004/071742 Al; 2004/071746 Al; 2004/072719 Al; 2004/072720 Al; 2006/0039934 Al; 2003/203829 Al;
2003/195133 Al; 2004/087477 Al; 2004/0106536 Al; and US Patents 6,645,479 B I;
6,200,949 BI; 4,882,220; 4,917,920; 4,514,461; 6,106,875 and 4,234,627, 3,594,328 and US RE 32713, PCT Patent Application: WO 2009/134234 Al, WO 2006/127454 A2, WO 2010/079466 A2, WO 2010/079467 A2, WO 2010/079468 A2, WO
2010/084480 A2.
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-coyalently 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 CLogP greater than about 2. Molecule-Assisted Delivery (MAD) may also include those described in USP 7,119,060 and USP
5,506,201.
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 haft 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. Amine Assisted Delivery (AAD): The amine-assisted delivery technology approach utilizes materials that contain an amine group to increase perfume deposition or modify perfume release during product use. There is no requirement in this approach to pre-complex or pre-react the perfume raw material(s) and amine prior to addition to the product. In one aspect, amine-containing AAD materials suitable for use herein may be non-aromatic; for example, polyalkylimine, such as polyethyleneimine (PEI), or polyvinylamine (PVAm), or aromatic, for 5 example, anthranilates. Such materials may also be polymeric or non-polymeric. In one aspect, such materials contain at least one primary amine. This technology will allow increased longevity and controlled release also of low ODT perfume notes (e.g., aldehydes, ketones, enones) via amine functionality, and delivery of other PRMs, without being bound by theory, via polymer-assisted delivery for polymeric amines. Without technology, volatile top notes can be 10 lost too quickly, leaving a higher ratio of middle and base notes to top notes. The use of a polymeric amine allows higher levels of top notes and other PRMS to be used to obtain freshness longevity without causing neat product odor to be more intense than desired, or allows top notes and other PRMs to be used more efficiently. In one aspect, AAD systems are effective at delivering PRMs at pH greater than about neutral. Without wishing to be bound by theory, 15 conditions in which more of the amines of the AAD system are deprotonated may result in an increased affinity of the deprotonated amines for PRMs such as aldehydes and ketones, including unsaturated ketones and enones such as damascone. In another aspect, polymeric amines are effective at delivering PRMs at pH less than about neutral. Without wishing to be bound by theory, conditions in which more of the amines of the AAD system are protonated may result in a 20 decreased affinity of the protonated amines for PRMs such as aldehydes and ketones, and a strong affinity of the polymer framework for a broad range of PRMs. In such an aspect, polymer-assisted delivery may be delivering more of the perfume benefit; such systems are a subspecies of AAD and may be referred to as Amine- Polymer-Assisted Delivery or APAD. In some cases when the APAD is employed in a composition that has a pH of less than seven, such APAD systems may also be considered Polymer-Assisted Delivery (PAD). In yet another aspect, AAD and PAD systems may interact with other materials, such as anionic surfactants or polymers to form coacervate and/or coacervates-like systems. ht another aspect, a material that contains a heteroatom other than nitrogen, for example sulfur, phosphorus or selenium, may be used as an alternative to amine compounds. In yet another aspect, the aforementioned alternative compounds can be used in combination with amine compounds. In yet another aspect, a single molecule may comprise an amine moiety and one or more of the alternative heteroatom moieties, for example, thiols, phosphines and selenols. Suitable AAD systems as well as methods of making same may be found in US Patent Applications 2005/0003980 Al;
2003/0199422 Al;
2003/0036489 Al; 2004/0220074 Al and USP 6,103,678.
V. 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 Al and Al and US Patents 5,552,378; 3,812,011; 4,317,881; 4,418,144 and 4,378,923.
VI. 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 USPA 2005/0003980 Al and USP 6,458,754 BI.
VII. 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 Al and US Patents 5,858,959; 6,245,732 BI; 6,048,830 and 4,539,135.
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 USP 5,651,976.
VIII. Pro-Perfume (PP): This technology refers to perfume technologies that result from the reaction of perfume materials with other substrates or chemicals to form materials that have a covalent bond between one or more PRMs and one or more carriers. The PRM is converted into a new material called a pro-PRM (i.e., pro-perfume), which then may release the original PRM
upon exposure to a trigger such as water or light. Pro-perfumes may provide enhanced perfume delivery properties such as increased perfume deposition, longevity, stability, retention, and the like. Pro-perfumes include those that are monomeric (non-polymeric) or polymeric, and may be pre-formed or may be formed in-situ under equilibrium conditions, such as those that may be present during in-product storage or on the wet or dry situs. Nonlimiting examples of pro-perfumes include Michael adducts (e.g., beta-amino ketones), aromatic or non-aromatic imines (Schiff bases), oxazolidines, beta-keto esters, and orthoesters. Another aspect includes compounds comprising one or more beta-oxy or beta-thio carbonyl moieties capable of releasing a PRM, for example, an alpha, beta-unsaturated ketone, aldehyde or carboxylic ester. The typical trigger for perfume release is exposure to water; although other triggers may include enzymes, heat, light, pH change, autoxidation, a shift of equilibrium, change in concentration or ionic strength and others. For aqueous-based products, light-triggered pro-perfumes are particularly suited. Such photo-pro-perfumes (PPPs) include but are not limited to those that release coumarin derivatives and perfumes and/or pro-perfumes upon being triggered.
The released pro-perfume may release one or more PRMs by means of any of the above mentioned triggers. In one aspect, the photo-pro-perfume releases a nitrogen-based pro-perfume when exposed to a light and/or moisture trigger. In another aspect, the nitrogen-based pro-perfume, released from the photo-pro-perfume, releases one or more PRMs selected, for example, from aldehydes, ketones (including enones) and alcohols. In still another aspect, the PPP releases a dihydroxy coumarin derivative. The light-triggered pro-perfume may also be an ester that releases a coumarin derivative and a perfume alcohol. In one aspect the pro-perfume is a dimethoxybenzoin derivative as described in USPA 2006/0020459 Al. In another aspect the pro-perfume is a 3', 5'-dimethoxybenzoin (DMB) derivative that releases an alcohol upon exposure to electromagnetic radiation. In yet another aspect, the pro-perfume releases one or more low ODT
PRMs, including tertiary alcohols such as linalool, tetrahydrolinalool, or dihydromyrcenol.
Suitable pro-perfumes and methods of making same can be found in US Patents 7,018,978 B2;
6,987,084 B2; 6,956,013 B2; 6,861,402 Bl; 6,544,945 Bl; 6,093,691; 6,277,796 BI; 6,165,953;

a.) Amine Reaction Product (ARP): For purposes of the present application, ARP
is a subclass or species of PP. One may also use "reactive" polymeric amines in which the amine functionality is pre-reacted with one or more PRMs to form an amine reaction product (ARP). Typically the reactive amines are primary and/or secondary amines, and may be part of a polymer or a monomer (non-polymer). Such ARPs may also be mixed with additional PRMs to provide benefits of polymer-assisted delivery and/or amine-assisted delivery. Nonlimiting examples of polymeric amines include polymers based on polyalkylirnines, such as polyethyleneimine (PEI), or polyvinylamine (PVAm). Nonlimiting examples of monomeric (non-polymeric) amines include hydroxyl amines, such as 2-aminoethanol and its alkyl substituted derivatives, and aromatic amines such as anthranilates. The ARPs may be premixed with perfume or added separately in leave-on or rinse-off applications. In another aspect, a material that contains a heteroatom other than nitrogen, for example oxygen, sulfur, phosphorus or selenium, may be used as an alternative to amine compounds.
In yet another aspect, the aforementioned alternative compounds can be used in combination with amine compounds. In yet another aspect, a single molecule may comprise an amine moiety and one or more of the alternative heteroatom moieties, for example, thiols, phosphines and selenols. The benefit may include improved delivery of perfume as well as controlled perfume release. Suitable ARPs as well as methods of making same can be found in USPA 2005/0003980 Al and USP 6,413,920 Bl.

stereoisomers of Table 1 PRMs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39,40, 41,42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86 and 87; and mixtures thereof. PRMs 1, 2, 5, 6, 8, 16, 20, 21, 24, 27, 28, 32, 33, 36, 40, 41, 52, 56, 58, 62, 82, 83, 86 are ketones. PRMs 9, 10, 18, 44, 45, 47, 53, 54, 59, 64, 78, 85 are aldehydes.

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 (shampoo or conditioner) 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-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).
4. GC column: J&W DB5TM MS, 30 M x 0.25 min ID, 1.0 Am film thickness obtained from J&W Scientific of Folsom, California, USA.
5. Carrier gas, helium, 1.5 ml/min. flow rate. =
6. The injector liner is a special SPME liner (0.75 mm ID) from Supelco.
7. The Detector is a model 5973 Mass Selective Detector obtained from Agilent Technologies, Inc., Wilmington, DE, USA having a source temperature of about 230 C, and a MS Quad temperature of about 150 'C.
Analysis procedure:
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 5 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. Desportion time is 5 minutes.
10 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.
15 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 ChemstationTM software obtained from Agilent Technologies, Inc., Wilmington, DE, USA..
20 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 25 ratios obtained in step 9.
(4) Perfume leakage can also be evaluated via% liquid-liquid extraction and gas chromatographic-mass spectrometric analysis When determining the % perfume leakage from Perfume Microcapsules in liquid detergent, 30 a fresh sample of liquid detergent with equal level of free perfume (without Perfume Microcapsules) must also be analysed in parallel for reference.
1.Preparation of an internal standard solution - Stock solution of tonalid : Weigh 70 mg tonalid and add 20 ml hexane p.a.
- Internal Standard Solution solution: Dilute 200 ml of stock solution in 20 ml hexane p.a.
- Mix to homogenize 2.Perfume extraction from liquid detergent without perfume microcapsules (reference) - Weigh 2 g of liquid detergent product into an extraction vessel - Add 2 ml of Internal Standard Solution and close vessel - Extract perfume by gently turning the extraction vessel upside-down for 20 times (manually) - Add spoon tip of Sodium Sulphate - After separation of layers, immediately transfer hexane-layer into Gas Chromatograph auto sampler-vial and cap vial - Inject splitless (1.5 1) into Gas Chromatograph injection-port - Run Gas Chromatographic-Mass Spectrometric analysis 3.Perfume extraction from liquid detergent with perfume microcapsules - Weigh 2 g of liquid detergent product into an extraction vessel - Add 2 ml of Internal Standard Solution and close vessel - Extract perfume by gently turning the extraction vessel upside-down for 20 times (manually) - Add spoon tip of Sodium Sulphate - After separation of layers, immediately transfer hexane-layer into Gas Chromatograph auto sampler-vial and cap vial - Inject splitless (1.5111) into Gas Chromatograph injection-port - Run Gas Chromatographic-Mass Spectrometric analysis 4. Calculation - The perfume leakage from capsules per individual Perfume Raw Material:
% perfume leakage = ((Area Perfume Raw Material caps x Area Internal Standard Solution ref x Weight ref) / (Area Internal Standard Solution caps x Area Perfume Raw Material ref x Weight caps)) x 100 (5) Odor Detection Threshold (OD'1') is 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 determinewhether a material has a threshold below 50 parts per bullion, 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 noticeability. 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 HD detector, 7673 Autosampler Column: J&W Scientific DB-lrm Length: 30 meters, 0.25 millimeter 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 EXAMPLES

A solution of n-butyllithium (2.2M in cyclohexane ¨ 1 eq.) is added drop wise to an ice cold solution of diisopropylamine (1 eq.) in dry THF (0.5 M). After stirring for 10 minutes at this temperature, i-butyronitrile (1 eq.) is added to the mixture. (1R,5S)-2-(chloromethyl)-6,6-dimethylbicyclo[3.1.1]hept-2-ene (1 eq.) is added after another mixing of 10 minutes at 0 C.
Reaction conversion is followed by GC-MS and seen as complete after 30 minutes stirring at 0 'C. The reaction is quenched by addition of a saturated NH4C1 aqueous solution and extracted with Et20. The combined organic layers are dried over MgSO4 and concentrated under reduced pressure. The resulting oil is purified using a quick filtration over silica by elution with a petroleum ether- Et70 mixture (9-1). Concentration of the eluent under reduced pressure resulted in the compound as a colorless oil (84% yield).
