Patent Application
20080305977
The present application relates to perfume systems and consumer products comprising perfumes and/or such perfume systems, as well as processes for making and using such perfume systems and consumer products.
Consumer products may comprise one or more perfumes and/or perfume 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 systems provide desirable odors, consumers continue to seek products that have scents that may be long lasting and that are tailored to their individual desires—unfortunately the pool of perfumes and perfume systems that is available is still too limited to meet such desires. Thus, perfumers need an ever larger pool of perfumes and perfume systems.
Applicants believe that the compositions disclosed herein meet such need as such compositions include perfume reaction products, and perfumed compositions comprising new perfumes and perfume systems including perfume reaction products.
The present application relates to perfume systems and consumer products comprising new perfumes and/or such perfume systems, as well as processes for making and using such perfume 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 intended to be used or consumed in the form in which it is sold, and not intended for subsequent commercial manufacture or modification.

Suitable perfumes include perfumes having of Formulas I through VI below.
wherein
the bond between C-1 and C-2 is a single bond and the dotted line together with the bond between C-2 and C-3 represents a double bond; or
the bond between C-2 and C-3 is a single bond and the dotted line together with the bond between C-1 and C-2 represents a double bond. Such molecule being 1-(2-isobutylcyclohex-1-enyl)but-2-en-1-one and 1-(2-isobutylcyclohex-2-enyl)but-2-en-1-one.
wherein
R1 is hydrogen or methyl;
R2 is C1-C3 alkyl; and
the double bond between C-4′ and C-5′ is either in (E)- or (Z)-configuration.
An example of a molecule having Formula II is (4′Z)-2,2-dimethyl-5-(2′-methyloct-4′-enyl)-2,5-dihydrofuran.
The molecule having Formula III being known as 6-methoxy-1,5,6-trimethyl-5-(3-methylbut-2-enyl)cyclohex-1-ene.
The molecule having Formula IV being known as (E)-3-methyl-5-(2,2,3-trimethylcyclopent-3-enyl)pent-3-en-2-one.
The molecule having Formula V being known as (2E,5E/Z)-5,6,7-trimethylocta-2,5-dien-4-one.
The molecule having Formulae VI being known as (E)-1-(6-ethyl-2-methylcyclohex-3-enyl)but-2-en-1-one.
Molecules having Formulae I may be prepared by acylation of 1-isobutyl-cyclohexene with crotonyl chloride or crotonic anhydride in the presence of a Lewis acid leading to the monoconjugated butanone, i.e. a compound of formula (I) wherein the bond between C-1 and C-2 is a single bond and the dotted line together with the bond between C-2 and C-3 represents a double bond, that could be isomerized to the diconjugated butanone, i.e. a compound of Formula (I) wherein the bond between C-2 and C-3 is a single bond and the dotted line together with the bond between C-1 and C-2 represents a double bond, by heating in toluene in the presence of an acid e.g. PTSA. Examples 1 through 3 of the present application further illustrate such teachings
Molecules having Formula (II) may be prepared by the Wittig reaction of 3-methyl-5-oxopentyl acetate with C3-C5 alkyl triphenylphosphonium halides, and subsequent saponification resulting in 3-methyl substituted alk-5-enals. By reaction of these 3-methylalk-5-enals with Grignard reagents of but-3-yn-2-ol and 2-methylbut-3-yn-2-ol, respectively, double-unsaturated 1,4-diols are accessible, which can be cyclized to 2-methyl-substituted 5-(2′-methylalk-4′-enyl)-2,5-dihydrofurans by means of common dehydration reagents, such as potassium hydrogen sulphate. By modification of the condition of the Wittig reaction, the stereochemistry of the Δ4-double bond in the side chain can also be controlled. This as well as the synthesis or resolution of specific enantiomers or diastereoisomers is general state of the art; the general formula comprises not only all double-bond isomers, but also all possible enantiomeric and diastereomeric compositions. Due to simple cost constraints, the preparation of diastereoisomeric mixtures with cis-configured double bonds is, however, generally advantageous. Example 4 further illustrates such teachings.
Molecules having Formula (VI) can be made by Diels-Alder cycloaddition followed by aldol condensation with acetaldehyde and water elimination under conditions known in the art.
Molecules having Formulae III through V can also be made in accordance with the teachings of U.S. Pat. Nos. 4,052,341; 6,723,313 B2 and 7,078,570 B2.

No. 5,879,584; U.S. Pat. No. 5,691,297; U.S. Pat. No. 5,574,005; U.S. Pat. No. 5,569,645; U.S. Pat. No. 5,565,422; U.S. Pat. No. 5,516,448; U.S. Pat. No. 5,489,392; and U.S. Pat. No. 5,486,303.
Compositions containing the benefit agent delivery particle disclosed herein can be used to clean or treat a situs inter cilia a surface or fabric. Typically at least a portion of the situs is contacted with an embodiment of Applicants' composition, in neat form or diluted in a liquor, for example, a wash liquor and then the situs may be optionally washed and/or rinsed. In one aspect, a situs is optionally washed and/or rinsed, contacted with a particle according to the present invention or composition comprising said particle and then optionally washed and/or rinsed. For purposes of the present invention, washing includes but is not limited to scrubbing, and mechanical agitation. The fabric may comprise most any fabric capable of being laundered or treated in normal consumer use conditions. Liquors that may comprise the disclosed compositions may have a pH of from about 3 to about 11.5. Such compositions are typically employed at concentrations of from about 500 ppm to about 15,000 ppm in solution. When the wash solvent is water, the water temperature typically ranges from about 5° C. to about 90° C. and, when the situs comprises a fabric, the water to fabric ratio is typically from about 1:1 to about 30:1.
By Odor Intensity Index, it meant that the pure chemicals were diluted at 1% in Dipropylene Glycol, odor-free solvent used in perfumery. This percentage is more representative of usage levels. Smelling strips, or so called “blotters”, were dipped and presented to the expert panelist for evaluation. Expert panelists are assessors trained for at least six months in odor grading and whose gradings are checked for accuracy and reproducibility versus a reference on an on-going basis. For each amine compound, the panelist was presented two blotters: one reference (Me Anthranilate, unknown from the panelist) and the sample. The panelist was asked to rank both smelling strips on the 0-5 odor intensity scale, 0 being no odor detected, 5 being very strong odor present.
The following represents the Odor Intensity Index of an amine compound suitable for use in the present invention and according to the above procedure. In each case, numbers are arithmetic averages among 5 expert panelists and the results are statistically significantly different at 95% confidence level:
The amine reaction product is added to the unperfumed product base.
The unperfumed product base, wherein the abbreviations are as defined herein after for the examples, is as follows:
Levels of amine reaction product are selected so as to obtain an odor grade on the dry fabric of at least 20. After careful mixing, by shaking the container in case of a liquid, with a spatula in case of a powder, the product is allowed to sit for 24 hrs.
The resulting product is added into the washing machine in the dosage and in the dispenser appropriate for its category. The quantity corresponds to recommended dosages made for the corresponding market products: typically between 70 and 150 g for a detergent powder or liquid via current dosing device like granulette, or ariellette, and 25 and 40 ml for a liquid fabric softener. The load is composed of four bath towels (170 g) using a Miele W830 washing machine at 40° C. short cycle, water input: 15° Hardness at a temperature of 10-18° C., and full spin of 1200 rpm.
The same process is applied for the corresponding free perfume ingredient in consideration and is used as the reference. Dosages, fabric loads and washing cycles for the reference and the sample are identical.
Within two hours after the end of the washing cycle, the spinned but still wet fabrics are assessed for their odors using the scale mentioned below. Afterwards, half of the fabric pieces are hung on a line for 24 hr drying, away from any possible contaminations. Unless specified, this drying takes place indoor. Ambient conditions are at temperature between 18-25 C and air moisture between 50-80%. The other half is placed in a tumble drier and undergoes a full “very dry” cycle, i.e. in a Miele, Novotronic T430 set on program white-extra dry (full cycle). Tumble dry fabrics are also assessed on the next day. Fabrics are then stored in opened aluminum bags in an odor free room, and assessed again after 7 days.
Odor is assessed by expert panelists smelling carefully the fabrics. A 0-100 scale is used for all fabric odor gradings. The grading scale is as follows:
100=extremely strong perfume odor
75=very strong perfume odor
50=strong odor
40=moderate perfume odor
30=slight perfume odor
20=weak perfume odor
10=very weak perfume odor
0=no odor
A difference of more than 5 grades after 1 day and/or 7 days between the amine reaction product and the perfume raw material is statistically significant. A difference of 10 grades or more after one day and/or 7 days represents a step-change. In other words, when a difference of grade of more than 5, preferably at least 10 is observed between the amine reaction product and the perfume raw material, after either 1 day or 7 day or both 1 day and 7 days, it can be concluded that the amine reaction product is suitable for use in the present invention, provided that the amine compound fulfill the Odor Intensity Index.
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.
At −60° C., a solution of 1.7M tert-butyllithium in pentane (1000 ml, 1.7 mol, 2.1 eq.) in diethyl ether (800 ml) was treated dropwise within 1 h with isobutyl iodide (157 g, 0.81 mol, 1.0 eq.).

At the end of the addition, the reaction mixture was allowed to reach room temperature before being poured into ice/H2O) (500 ml) and acidified with concentrated HCl. The water phase was extracted with diethyl ether (300 ml) and the combined organic phases were washed with water (400 ml) and aqueous saturated NaCl solution (500 ml), dried (50 g MgSO4) and the solvent evaporated to give the crude 1-isobutylcyclohexanol (148 g).
In a flask equipped with a Vigreux-distillation apparatus, crude 1-isobutylcyclohexanol (200 g, 1.28 mol) was treated with phosphoric acid (100 g) and heated at 145° C. under vacuum (170 mbar). While 1-isobutylcyclohex-1-ene and water distilled (boiling point 60° C.), a second fraction of 1-isobutylcyclohexanol (492 g, 3.15 mol) was added dropwise in the reaction flask. At the end of the addition the thick reaction mixture was diluted with paraffin oil (100 ml) and additional phosphoric acid (50 g) and heated further (vacuum from 170 to 40 mbar). The distillate was decanted and the water phase extracted with pentane (100 ml). The combined org. phases were dried (MgSO4) and the solvent evaporated to give 1-isobutylcyclohex-1-ene (448 g, 78%).
At −70° C., a solution of tin tetrachloride (533 ml, 4.54 mol, 1.4 eq.) in dichloromethane (2.5 l) was treated with crotonyl chloride (350 ml, 90%, 3.24 mol, 1.0 eq.). The resulting solution was stirred for 30 min. and treated within 1.5 h with a solution of 1-isobutylcyclohex-1-ene (448 g, 3.24 mol) in dichloromethane (400 ml). The resulting mixture was stirred for 1 h at −70° C. and poured into ice/H2O. The org. phase was first washed with concentrated NaOH then with H2O, dried (MgSO4), and the solvent evaporated. Short-path Vigreux-distillation (0.15 mbar, bath temperature: 160° C.) of the crude product (592 g) gave a fraction (495 g, boiling range: 90-130° C.) that was redistilled using again a short-path Vigreux-column (0.11 mbar, bath temperature: 160° C.) to give (E)-1-(2-isobutylcyclohex-2-enyl)but-2-en-1-one (202 g, 30%). Boiling point: 120° C. (0.11 mbar).
A solution of (E)-1-(2-isobutylcyclohex-2-enyl)but-2-en-1-one (202 g, 0.979 mol) in toluene (3 l) was treated with p-toluenesulfonic acid monohydrate (3.7 g, 19.5 mmol), refluxed during 18 h and poured into water. The org. phase was dried (MgSO4) and concentrated. Short-path Vigreux-distillation (0.11 mbar, bath temperature: 140-160° C.) of the crude product (181 g, 68:32 mixture of (E)-1-(2-isobutylcyclohex-1-enyl)but-2-en-1-one/(E)-1-(2-isobutylcyclohex-2-enyl)but-2-en-1-one) gave a mixture of butenones (181 g, 90%, boiling range 90-110° C.) that was redistilled (0.08 mbar, bath temperature: 150° C.) using a Sulzer-column affording a 60:40 mixture of (E)-1-(2-isobutylcyclohex-1-enyl)but-2-en-1-one/(E)-1-(2-isobutylcyclohex-2-enyl)but-2-en-1-one (145.6 g, 72%).
A solution of (E)-1-(2-isobutylcyclohex-2-enyl)but-2-en-1-one (2.7 g, 13.1 mmol) in toluene (28 ml) was treated with p-toluenesulfonic acid monohydrate (70 mg, 0.37 mmol), refluxed during 18 h and poured into water. The water phase was extracted three times with diethyl ether and the combined org. phases were washed with a saturated aqueous solution of sodium bicarbonate, dried (MgSO4) and concentrated. FC (400 g SiO2, hexane/diethylether 90:0.5) of the crude product (3.2 g, 64:36 mixture of (E)-1-(2-isobutylcyclohex-1-enyl)but-2-en-1-one (B)/(E)-1-(2-isobutylcyclohex-2-enyl)but-2-en-1-one (A)) gave a first fraction (0.31 g, 11%, 10:90 B/A), a second fraction (0.52 g, 19%, 71:29 B/A), and a third fraction (0.39 g, 14%, 91:9 B/A).
Under an atmosphere of nitrogen, a solution of 46.3 g (413 mmol) of potassium tert-butoxide in 250 mL of dry THF was a added between −15° C. and −10° C. to a stirred mixture of 150 g (376 mmol) butyl triphenylphosphonium bromide in 500 mL of dry THF. After complete addition, stirring was continued at −10° C. for 30 min, prior to the dropwise addition of 65.3 g (413 mmol) of 3-methyl-5-oxopentyl acetate in 250 ml of dry THF within a period of 30 min. Stirring was continued a further 15 min at −10° C., before the cooling bath was removed and the reaction mixture was allowed to warm to room temp. After 3 h of stirring at room temp., the reaction mixture was poured into 1 L of water, the organic layer separated and aqueous one extracted twice with 1 L of ether each. The combined organic extracts were washed with water and brine, dried with sodium sulphate, and concentrated under reduced pressure. The crude material (191 g) was purified by flash chromatography (1.00 kg of silica gel, pentane/ether, 19.1, Rf=0.40) to afford 57.9 g (78%) of (5Z)-3-methylnon-5-enyl acetate as a colourless liquid.
In the next step, 55.0 g (278 mmol) of this (5Z)-3-methylnon-5-enyl acetate was dissolved in 600 ml of a 1:1 mixture of ethanol and water. With vigorous stirring, 55.5 g (1.39 mol) of sodium hydroxide was added, and the reaction mixture was subsequently heated to reflux for 3 h. After the reaction mixture had cooled to room temp., the ethanol was removed in a rotary evaporator under reduced pressure, and the resulting residue diluted with 300 mL of water. The crude product was extracted twice with 500 ml of ether each, and the combined organic extracts were washed twice with 300 ml of brine. After drying with sodium sulphate and removal of the solvent under reduced pressure, the resulting residue (51.2 g) was purified by flash chromatography (1.00 kg of silica gel, pentane/ether, 9:1, Rf=0.11) to provide 39.9 g (92%) of (5Z)-3-methylnon-5-en-1-ol as a colourless liquid.
A solution of 10.4 g (95.6 mmol) of ethyl bromide in 40 mL of dry tetrahydrofuran was added dropwise over a period of 30 min to a vigorously stirred suspension of 2.32 g (95.6 mmol) of magnesium turnings in 15 mL of dry tetrahydrofuran, with the reaction being initiated by occasional heating with a heat gun. After stirring the reaction mixture for 90 min under reflux, it was allowed to cool down to room temp., and a solution of 3.54 g (42.2 mmol) of 2-methylbut-3-yn-2-ol in 40 mL of dry tetrahydrofuran was added dropwise with stirring. The reaction mixture was then again refluxed for 3 h, the heating bath removed and a solution of 6.50 g (42.2 mmol) of (5Z)-3-methylnon-5-en-1-ol in 40 mL of dry tetrahydrofuran added at room temp. with stirring over a period of 30 min. The reaction mixture was refluxed with stirring overnight, allowed to cool to room temp., and quenched by pouring into 100 mL of an aqueous satd. NH4Cl solution. The organic layer was separated, and the aqueous one extracted three times with 500 mL of ether each. The combined organic extracts were dried with sodium sulphate, and concentrated to dryness in a rotary evaporator.

At room temp., 520 mg (0.488 mmol) of 10% palladium on barium sulphate and 190 mg (1.47 mmol) of quinoline were added to a stirred solution of 7.70 g (32.3 mmol) of this (9Z)-2,7-dimethyltridec-9-en-3-yne-2,5-diol in 170 mL of ethanol. The flask was evacuated and flushed with nitrogen three times, and three times evacuated and flushed with hydrogen. The resulting reaction mixture was then stirred for 1.5 h under an atmosphere of hydrogen at ambient pressure and temperature, prior to evacuation and ventilation with nitrogen. The reaction flask was opened to air, and the catalyst filtered off by suction over a pad of Celite. After removal of the solvent in a rotary evaporator under reduced pressure, the resulting crude product (8.07 g) was purified by flash chromatography (100 g of silica gel, pentane/ether, 1:1, 0.28) to afford 4.28 g (55%) of (3Z,9Z)-2,7-dimethyltrideca-3,9-diene-2,5-diol as a colorless oil.
