Patent Application
20200131450
The present application relates to consumer products and perfume delivery systems using organoleptic compounds, as well as processes for making and using such consumer products and perfume delivery systems.
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 or an area 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 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 perfume community's needs. Thus, perfumers need an ever-larger pool of perfume raw materials and perfume delivery systems.

The mixture of Structures 9 and 10 was described as having green, floral and woody notes.
In comparison of the two mixtures obtained from EXAMPLE I and EXAMPLE II, respectively, the mixture of Structures 1-4 exhibited significantly stronger, longer lasting and more complex notes. In contrast, the mixture of Structures 9 and 10 appeared weak, thin, less natural and harsh. The resinous and coniferous notes that were present in the Structures 1-4 mixture were also missing in the Structures 9 and 10 mixture.
The mixture of (E)-1-((1R,6R)-4,6-dimethylcyclohex-3-en-1-yl)-2-methylpent-1-en-3-one, (E)-1-((1S,6S)-3,6-dimethylcyclohex-3-en-1-yl)-2-methylpent-1-en-3-one, (E)-1-((1R,6S)-4,6-dimethylcyclohex-3-en-1-yl)-2-methylpent-1-en-3-one and (E)-1-((1S,6R)-3,6-dimethylcyclohex-3-en-1-yl)-2-methylpent-1-en-3-one (25.0 g, 121 mmol) is dissolved in tetrahydrofuran (250 ml, 0.5M). The mixture is cooled to 0° C. and lithium aluminum hydride (2.3 g, 60.5 mmol) is added in small portions. The mixture is then allowed to warm up to room temperature. Stirring was continued for 50 minutes at this temperature to reach full conversion of the starting material.
The mixture is cooled to 0° C. Water (2.3 ml), aqueous sodium hydroxide (15%)(2.3 ml) and water (4.6 ml) are added to the mixture consecutively and the mixture is stirred at room temperature overnight. The mixture is filtered over a layer of celite, the filter cake is washed with tetrahydrofuran (50 ml). The filtrate is evaporated under reduced pressure and dried under high vacuum to yield 20 g of product. (79% yield)
The following ingredients are weighted off in a glass vial:
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:
25 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.) is dissolved and mixed in 200 grams deionized water. The pH of the solution is adjusted to pH of 4.0 with sodium hydroxide solution. 8 grams 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 comprising Structures 1, 2, 3, 4, or isomers thereof of Formula I is added to the previous mixture under mechanical agitation and the temperature is raised to 50° 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 10 grams of butyl acrylate-acrylic acid copolymer emulsifier (Colloid C351, 25% solids, pka 4.5-4.7, Kemira), 120 grams of distilled water, sodium hydroxide solution to adjust pH to 4.8, 25 grams of partially methylated methylol melamine resin (Cymel 385, 80% solids, Cytec). This mixture is heated to 70° C. and maintained overnight 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. An average capsule size of 30 um is obtained as analyzed by a Model 780 Accusizer.
Suitable perfume capsules can be purchased from Encapsys, (825 East Wisconsin Ave, Appleton, Wis. 54911), and are made as follows: a first oil phase, consisting of 37.5 g perfume, 0.2 g tert-butylamino ethyl methoacrylate, and 0.2 g beta hydroxyethyl acrylate is mixed for about 1 hour before the addition of 18 g CN975 (Sartomer, Exter, Pa.). The solution is allowed to mix until needed later in the process.
A second oil phase consisting of 65 g of the organoleptic compound of Formula I and stereoisomers thereof, 84 g isopropyl myristate, 1 g 2,2′-azobis(2-methylbutyronitrile), and 0.8 g 4,4′-azobis[4-cyanovaleric acid] is added to a jacketed steel reactor. The reactor is held at 35° C. and the oil solution in mixed at 500 rpm's with a 2″ flat blade mixer. A nitrogen blanket is applied to the reactor at a rate of 300 cc/min. The solution is heated to 70° C. in 45 minutes and held at 70° C. for 45 minutes, before cooling to 50° C. in 75 minutes. At 50° C., the first oil phase is added and the combined oils are mixed for another 10 minutes at 50° C.
A water phase, containing 85 g Celvol 540 PVA (Sekisui Specialty Chemicals, Dallas, Tex.) at 5% solids, 268 g water, 1.2 g 4,4′-azobis[4-cyanovaleric acid], and 1.1 g 21.5% NaOH, is prepared and mixed until the 4,4′-AZOBIS[4-CYANOVALERIC ACID] dissolves. The water phase pH for this batch was 4.90.
Once the oil phase temperature has decreased to 50° C., mixing is stopped and the water phase is added to the mixed oils. High shear agitation is applied to produce an emulsion with the desired size characteristics (1900 rpm's for 60 minutes.)
The temperature was increased to 75° C. in 30 minutes, held at 75° C. for 4 hours, increased to 95° C. in 30 minutes, and held at 95° C. for 6 hours. The batch was allowed to cool to room temperature.

To form a silicone-based pro-perfume, 50.0 g of an aminosilicone (KF-8003 silicone, available from Shin-Etsu Silicones; 0.0264 mol) and 5.45 g of an organoleptic compound according to the present disclosure (0.0264 mol) are weighed into a 250 mL three-neck flask containing a magnetic stir bar. The reaction mixture is stirred for 24 h at 80° C. under nitrogen sweep (to remove water). Formation of imine bond is analyzed using 13C-NMR.
The general reaction is represented according to the equation below, where R—NH2 represents the starting aminosilicone. It is understood that the starting aminosilicone includes a plurality of —NH2 moieties, and that the reaction provided below may occur at more than one —NH2 moiety on the aminosilicone. This advantageously results in a plurality of organoleptic compounds being loaded onto the aminosilicone.
The pro-perfume reaction product may be suitable for formulating into a consumer product, such as a fabric care product (e.g., a liquid fabric enhancer).
It is further understood that different aminosilicones may be substituted for the exemplified KF-8003 aminosilicone, but that the reaction shown above may remain substantially the same.
