Description

PERFUME SYSTEMS

FIELD OF INVENTION

The present application relates to perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or perfume delivery systems, as well as processes for making and using such perfume raw materials, perfume delivery systems and consumer products.

BACKGROUND OF THE INVENTION

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 to a product and/or a situs that is contacted with such a product. While current perfumes and perfume delivery systems provide desirable fragrances, 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 USPA 2008/0305977 Al) - 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 perfumes, including the delivery systems, disclosed herein expand the perfume community's options, as such perfume raw materials can provide variations on character and such perfumes can provide desired odor profiles in consumer products. In certain aspects, such perfume delivery systems comprising such perfume raw materials may provide variations on character 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), ClogP, boiling point and/or odor detection threshold.

SUMMARY OF THE 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.

II. Molecule- Assisted Delivery (MAD): Non-polymer materials or molecules may also serve to improve the delivery of perfume. Without wishing to be bound by theory, perfume may non- covalently interact with organic materials, resulting in altered deposition and/or release. Non- limiting examples of such organic materials include but are not limited to hydrophobic materials such as organic oils, waxes, mineral oils, petrolatum, fatty acids or esters, sugars, surfactants, liposomes and even other perfume raw material (perfume oils), as well as natural oils, including body and/or other soils.

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 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.

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 the amine prior to addition to the product. In one aspect, amine - containing AAD materials suitable for use herein may be non-aromatic, for example,

poly alky limine, 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. 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.

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.

VI. Starch Encapsulated Accord (SEA): SEA's are starch encapsulated perfume materials. Suitable starches include modified starches such as hydrolyzed starch, acid thinned starch, starch having hydrophobic groups, such as starch esters of long chain hydrocarbons (C5 or greater), starch acetates, starch octenyl succinate and mixtures thereof. In one aspect, starch esters, such as starch octenyl succinates, are employed. Suitable perfumes for encapsulation include the HIA perfumes, including those having a boiling point determined at the normal standard pressure of about 760 mmHg of 275 °C or lower, an octanol/water partition coefficient P of about 2000 or higher and an odor detection threshold of less than or equal 50 parts per billion (ppb). In one aspect, the perfume may have logP of 2 or higher.

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. 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. Non-limiting examples of pro-perfumes include Michael adducts (e.g. , beta-amino ketones), aromatic or non-aromatic imines (Schiffs 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.

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, typically PRMs that contain a ketone moiety and/or an aldehyde moiety, to form the 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. Non-limiting examples of polymeric amines include polymers based on polyalkylimines, such as polyethyleneimine (PEI), or polyvinylamine (PVAm). Non- limiting examples of monomelic (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.

TEST METHODS

It is understood that the test methods that are disclosed in the Test Methods Section of the present application should be used to determine the respective values of the parameters of Applicants' invention as such invention is described and claimed herein. (1) ClogP

The logP values of many perfume ingredients have been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, California, contains many, along with citations to the original literature.

However, the logP values are most conveniently calculated by the "CLOGP" program, also available from Daylight CIS. This program also lists experimental logP values when they are available in the Pomona92 database. The "calculated logP" (ClogP) is determined by the fragment approach of Hansch and Leo ( cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment approach is based on the chemical structure of each perfume ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding. The ClogP values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental logP values in the selection of perfume ingredients which are useful in the present invention.

(2) Boiling Point

Boiling point is measured by ASTM method D2887-04a, "Standard Test Method for Boiling Range Distribution of Petroleum Fractions by Gas Chromatography," ASTM International.

(3) Headspace Ratio

(a) Obtain a fragrance free consumer product formulation.

(b) Obtain fragrance microcapsules whose water content has been adjusted to achieve a

perfume content of 25wt% in the aqueous slurry.

(c) Prepare Sample A by adding 2.0 grams of the fragrance microcapsule aqueous slurry to

95 grams of the fragrance free consumer product formulation. Then add 3.0 grams of deionized water to balance the formulation to 100 grams. Age this formulation for 1 week at 40 degrees Centigrade,

(d) Prepare Sample B by adding 0.50 grams of the neat fragrance to 95 grams of fragrance free consumer product formulation. Then add 4.5 grams of deionized water to balance the formulation to 100 grams. Age this formulation for 1 week at 40 degrees Centigrade.

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 _ A

Sample B, J-f , where Hs_ampie_A is the headspace concentration of a consumer

Sample _ B

product formulation Sample A, and Hs_ampie_B is the headspace concentration of a consumer product formulation Sample B. 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

Sample _ B

concentration of Sample A, J-f , where Hs_ampie_A is the headspace concentration of

Sample _ A

a consumer product formulation Sample A, and Hs_ampie_B is the headspace concentration of a consumer product formulation Sample B.

Solid-Phase Micro-Extraction (SPME)-Gas Chromatography/Mass Spectrometry is used to measure the level of perfume raw materials in the headspace of products. 1.0 grams of the 1 week at 40 degrees Centigrade aged sample are placed into a clean 20 ml headspace vial and allowed to equilibrate for at least 2 hours at room temperature. The samples are then analyzed using the MPS2-SMPE-GC-MS analysis system (GC-

02001-0153, MSD-02001 -0154, MPS2-02001-0155).

Apparatus:

1. 20 ml headspace vial

2. Timer.

3. Gas Chromatograph (GC): Agilent model 6890 with a CIS-4 injector (Gerstel, Mulheim,

Germany) and MPS-2 Autosampler and TDU. For SPME analysis, we used the split/splitless injector (not the CIS-4 injector).

4. GC column: J&W DB-5 MS, 30 M x 0.25 mm ID, 1.0 m 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 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 urn, 24 ga, 1 cm length). Sampling time is 5 minutes.

3. Injector temperature is at 260C.

4. Then GC-MS analysis run is started. Desorption time is 5 minutes.

5. The following temperature program is used:

i) an initial temperature of about 50 °C which is held for 3 minutes,

ii) increase the initial temperature at a rate of about 6 °C/min until a temperature of about 250 °C is reached, then 25 °C/min to 275 °C, hold at about 275 °C for 4.67 minute.

6. Perfume compounds are identified using the MS spectral libraries of John Wiley & Sons and the National Institute of Standards and Technology (NIST), purchased and licensed through Hewlett Packard.

7. Chromatographic peaks for specific ions are integrated using the Chemstation software obtained from Agilent Technologies, Inc., Wilmington, DE, USA..

8. The ratio for each PRM is calculated by dividing the peak area for the perfume raw

material in Sample A by the peak area in Sample B.

9. Each ratio is then weighted by that perfume raw material's weight composition in the perfume.

10. The Headspace Ratio is calculated as the sum of the individual perfume raw material ratios obtained in step 9. (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, a fresh sample of liquid detergent with equal level of free perfume (without Perfume Microcapsules) must also be analyzed 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 μΐ 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 (1.5μ1) 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

- Add spoon tip of Sodium Sulphate

- Inject splitless (1.5μ1) 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 (OPT)

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, 0.25millmeter 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

A clean, dry 1.5 L three-neck reaction flask fitted with a condenser, mechanical agitator and thermometer was purged with argon. To it were charged dichloromethane (360 mL) and 4- hydroxy-2,5-dimethylfuran-3(2H)-one (2) (60.0 g, 97%, 454 mmol, 1.0 eq). The agitator was turned on, the reaction mixture was blanketed with argon and the flask was cooled to an internal temperature of -17°C (using a mixture of ice and dry-ice). To this clear pale orange solution was added, by means of a syringe, over 10 minutes triethylamine (55.7 g, 99%, 545 mmol, 1.2 eq). The reaction mixture changed to a yellow colour. The internal temperature was reduced to -24°C and to the clear yellow solution was added methyl chloroformate (41.2 g, 99%, 432 mmol, 0.95 eq) over two hours via a syringe using a syringe pump. During the addition the internal temperature rose from -24°C to -17°C. The reaction mixture changed progressively from a clear yellow solution to a cloudy yellow suspension. The reaction mixture was stirred for 2h30 while allowing the internal temperature to rise from -17°C to +7°C. The reaction mixture was diluted with ethyl acetate (1.5 L). The organic phase was then washed with water (7 x 1 L) till a GC analysis of the organic phase indicated the complete absence of 2. The organic phase was concentrated under reduced pressure (45 °C, 100 mbar -> 3 mbar) to obtain the crude 1 as a viscous yellow oil (55.76 g, 98.0% pure by GC). The crude was flash distilled (111-152°C pot, 93-95°C vapour, 0.6 mbar) to obtain 1 as a very pale yellow viscous liquid (55.3 g, 98.5% pure by GC; 63% yield). The semi-pure 1 obtained from several batches run as detailed above was combined (477.7 g) and purified by fractional distillation through a 7 cm packed (glass beads) column (110-121°C pot, 92-95°C vapour, 0.6-0.7 mbar). All fractions were analysed by GC and those that had a purity in excess of 98.5% were combined to obtain the pure 1 as a very pale yellow oil (466.8 g, 98.8% pure). 1H-NMR (400 MHz, CDC1₃ , δ): 1.49 (d, J = 7.2 Hz, 3H), 2.23 (d, J = 0.8 Hz, 3H), 3.89

Example 2: Preformed Amine Reaction Product

The following ingredients are weighted off in a glass vial:

1. 50% of the perfume material comprising one or more Table 1 PRMs

2. 50% of Lupasol WF (CAS# 09002-98-6) from BASF, is put at 60°C in warm water bath for 1 hour before use.

Mixing of the two ingredients is done by using the Ultra- Turrax T25 Basic equipment (from IKA) during 5 minutes. When the mixing is finished the sample is put in a warm water bath at 60°C for + 12 hours. A homogenous, viscous material is obtained.

In the same way as described above different ratios between the components can be used:

Example 3: 84wt% Core / 16wt% Wall Melamine Formaldehyde (MF) Capsule (PAD Reservoir

System

17 grams of butyl acrylate- acrylic acid copolymer emulsifier (Colloid C351, 25% solids, pka 4.5- 4.7, (Kemira Chemicals, Inc. Kennesaw, Ga. U.S.A.) and 17 grams of polyacrylic acid (35% solids, pKa 1.5-2.5, Aldrich) are dissolved and mixed in 200 grams deionized water. The pH of the solution is adjusted to pH of 6.0with sodium hydroxide solution. 7grams of partially methylated methylol melamine resin (Cymel 385, 80% solids, (Cytec Industries West Paterson, N.J., U.S.A.)) is added to the emulsifier solution. 200 grams of perfume oil is added to the previous mixture under mechanical agitation and the temperature is raised to 45° C. After mixing at higher speed until a stable emulsion is obtained, the second solution and 4 grams of sodium sulfate salt are added to the emulsion. This second solution contains 3 grams of polyacrylic acid polymer (Colloid C121, 25% solids (Kemira Chemicals, Inc. Kennesaw, Ga. U.S.A.), 100 grams of distilled water, sodium hydroxide solution to adjust pH to 6.0, 10 grams of partially methylated methyol melamine resin (Cymel 385, 80% Cytec). This mixture is heated till 85C and maintained 8 hours with continuous stirring to complete the encapsulation process. 23 grams of acetoacetamide (Sigma-Aldrich, Saint Louis, Mo. U.S.A.) is added to the suspension. Salts and structuring agents can then still be added to the slurry.
