Patent Application
20150275132
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.
Consumer 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), Clog P, boiling point and/or odor detection threshold.
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.
As used herein “consumer product” means baby care, beauty care, fabric & home care, family care, feminine care, health care, snack and/or beverage products or devices generally intended to be used or consumed in the form in which it is sold.

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:
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 polysaccharides 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.
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 CLogP greater than about 2. Molecule-Assisted Delivery (MAD) may also include those described in U.S. Pat. No. 7,119,060.
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.
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 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 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, 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 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. In 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 A1.
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.
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.
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.
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 A1. 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.

(1) Clog P
(2) Boiling Point
(3) Headspace Ratio
The Headspace Ratio for determining perfume leakage from a perfume delivery system is defined as the headspace concentration of Sample A divided by the headspace concentration of Sample B,
where HSample
The Headspace Ratio for determining perfume delivery efficiency from a perfume delivery system is defined as the headspace concentration of Sample B divided by the headspace concentration of Sample A,
where HSample
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).
(4) Perfume Leakage can Also be Evaluated Via % Liquid-Liquid Extraction and Gas Chromatographic-Mass Spectrometric Analysis

2. Perfume Extraction from Liquid Detergent without Perfume Microcapsules (Reference)
3. Perfume Extraction from Liquid Detergent with Perfume Microcapsules
4. Calculation
% 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
(5) Odor Detection Threshold (ODT)
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 millimeter inside diameter, 1 micrometer film thickness
Method:
(6) Coolant Screening on the TRPM8 Receptor
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.
A. The assessors must be able to differentiate the sweat odour from an odourless solvent (dipropylene glycol=DPG).
To do this, several cardboard smelling strips are immersed in a highly dilute solution (0.1% in DPG) of the 3-mercapto-3-methyl-hexan-1-ol. In addition, several smelling strips are immersed in DPG. Only those assessors who can perfectly differentiate the smelling strips in a test with 3-mercapto-3-methyl-hexan-1-ol—3-mercapto-3-methyl-hexan-1-ol—DPG and DPG—DPG—3-mercapto-3-methyl-hexan-1-ol take part in further tests.
B. Several concentrations of 3-mercapto-3-methyl-hexan-1-ol are then placed in a container with a volume of 7 l filled with air. The samples are sorted by the assessors according to intensity, i.e. odour strength. The series of concentrations must be correctly recognised and evaluated by the assessors. Assessors who have passed both tests can take part in the raw material test described in the following.
The test materials examined are either individual perfume raw materials (PRMs) or perfume oils. The test materials are evaluated by the selected assessors in a predefined gaseous sample with regard to intensity and residual odour strength of the 3-mercapto-3-methyl-hexan-1-ol, a target malodor compound. 1 mu/l of the test material and 5 mull of the dilute 3-mercapto-3-methyl-hexan-1-ol (0.1% in DPG) respectively are placed in a container with a volume of 7 l filled with air. The samples are kept at room temperature (20 deg. C.) for 15 h before evaluation. The individual samples are each evaluated by at least 8 assessors by smelling in comparison with a sample just with 3-mercapto-3-methyl-hexan-1-ol-solution. The mean value is then formed from the at least 8 values obtained for the respective raw material. The intensity of a test material describes the intensity of the test material perceived by odour by trained assessors, irrespective of the quality of the odour as a bad odour or pleasant odour. The stronger a test material smells the higher is the level of the intensity. The intensity is evaluated on a scale of 1 to 9. Level 1 means odourless, 9 means very strong odour detected. The term malodour reduction value describes in the present case the difference in intensity, i.e. the difference between the bad odour (malodour) of the malodour standard mixture and the test mixture.
The malodour standard mixture without test material, i.e., 3-mercapto-3-methyl-hexan-1-ol, receives intensity 6. The assessors are selected on the basis of their ability to reproducibly evaluate the strengths of odours. The assessors are trained before the series of tests to recognise the odour of 3-mercapto-3-methyl-hexan-1-ol.
While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
