Title: Consumer product compositions with perfume encapsulates

Description:
FIELD OF THE INVENTION 
     The present disclosure relates to consumer product compositions that include perfume encapsulates, where the perfume is characterized by a particular acid value. Related methods of making and using such compositions are also disclosed. 
     BACKGROUND OF THE INVENTION 
     Perfumes are often desirable ingredients to include in consumer products, such as laundry detergent, fabric softeners, and/or hair treatment products, such as shampoo or conditioners. The perfume can provide pleasing aesthetics to the product itself, or to the surface (e.g., a fabric or hair) treated with the product. 
     To improve perfume deposition and/or longevity, a perfume delivery system may be used. Core-shell encapsulation, where the perfume is encapsulated by a polymeric shell, is a technology that is commonly used in consumer products. The shell material may be selected from any number of polymers or mixtures thereof. When the shell is ruptured, the perfume is released. 
     However, the presence of certain perfume compounds in the core of the encapsulate may result in capsule instability. For example, WO2017/148504 discloses that certain perfume compounds, such as those containing aldehyde, acetal, and/or ester functionality, may form carboxylic acids when in the presence of atmospheric oxygen and/or by hydrolysis. It is believed that the resulting acids can impair the quality of the capsule wall and may result in perfume leakage out of the encapsulate. To remedy this problem, WO2017/148504 discloses that the selection of certain scent compositions, specifically those characterized by an acid value of no more than 5 mg KOH/g immediately before encapsulation (preferably determined according to DIN EN ISO 660: 2009-10), can provide improved capsule performance. 
     To obtain scent compositions or perfume mixtures with acid values of no more than 5 mg KOH/g, the formulator may need to limit the amount of certain ingredients, such as those containing aldehydes, acetals, and/or esters. However, these ingredients may be desirable to provide a certain scent experience to the consumer. 
     It would be desirable to provide perfume encapsulates and related consumer products that provide acceptable freshness benefits and/or low encapsulate leakage without unduly limiting the formulator to certain perfume formulations. 
     SUMMARY OF THE INVENTION 
     The present disclosure relates to consumer product compositions that include perfume encapsulates, the perfume being characterized by a particular acid value and the shell of the encapsulate including an acrylate material. 
     For example, the present disclosure relates to a consumer product composition that includes encapsulates, the encapsulates having a core and a shell surrounding the core, the core including a perfume, the perfume being characterized by an acid value of greater than 5.0 mg KOH/g immediately before encapsulation, as determined by the Acid Value Determination method described in the present disclosure, and the shell having a polymeric material, the polymeric material including an acrylate polymer; and a consumer product adjunct. 
     The present disclosure also relates to a method of treating a surface or article with consumer product compositions according to the present disclosure, where the method includes contacting the surface or article with the consumer product composition, optionally in the presence of water.

     DETAILED DESCRIPTION OF THE INVENTION 
     The present disclosure relates to certain core-shell encapsulates that include perfumes having relatively high acid values, as well as compositions and processes that relate to such encapsulates. It has been found that the selection of particular shell materials, specifically acrylate materials, can result in perfume encapsulates that provide surprisingly low leakage, even when containing perfumes characterized by, e.g., an acid value of greater than 5.0 mg KOH/g. It has surprisingly been found that the insufficient surfactant stability of the fragrance capsules is associated with the presence of aldehydic fragrances or fragrances with ester groups. Aldehydes have a tendency to form carboxylic acids in the presence of atmospheric oxygen; esters (and correspondingly also lactones) can saponify and in this way also form carboxyl groups. 
     Without wishing to be bound by theory, it is believed that for a radical-based capsule formation, and especially if part of this radical-based capsule formation is obtained from polymer formation from the oil phase, like for polyacrylate-based capsules, the sensitivity to the perfume materials such as aldehydes and esters, which may be prone to transforming into acids materials that are typically charged, is less compared to capsules formed by other formation mechanisms, such as coacervate formation, condensation reaction mechanism, and/or interfacial polymerization. It is believed that this lower sensitivity stems from the fact that the formed acids can interfere more easily into the other capsule formation mechanism due to their explicit charge as acids, and can therefore interact with the chemical species intended to make the capsule wall. 
     As it has been reported that encapsulated perfumes having an acid value above 5.0 mg KOH/g tend to leak and/or provide poor performance in compositions that comprise surfactant (such as hair shampoo, liquid detergent, or a fabric softener), the encapsulates of the present disclosure, which tend to have relatively low leakage rates, may be particularly preferred in compositions that contain surfactant and/or conditioning actives, or when used in applications that comprise such materials in an aqueous environment, such as during washing or other treatment operations, e.g., in a washing machine, shower, or bathtub.

     Consumer Product Composition 
     The present disclosure relates to consumer product compositions. The compositions may comprise encapsulates, as described in more detail below. 
     The composition may be a consumer product. The consumer product may be useful as a baby care, beauty care, fabric &amp; home care, family care, feminine care, or health care product or device. The composition may be a beauty care composition, a fabric care composition, a home care composition, or combinations thereof. 
     The composition may be a beauty care composition, such as a hair treatment product (including shampoo and/or conditioner), a skin care product (including a cream, lotion, or other topically applied product for consumer use), a shave care product (including a shaving lotion, foam, or pre- or post-shave treatment), personal cleansing product (including a liquid body wash, a liquid hand soap, and/or a bar soap), a deodorant and/or antiperspirant, or mixtures thereof. 
     The composition may be a fabric care composition, such as a laundry detergent composition (including a heavy-duty washing detergent), a fabric conditioning composition (including a fabric softening and/or enhancing composition), a laundry additive (e.g., a rinse additive), a fabric pre-treatment composition, a fabric refresher composition, or a mixture thereof. 
     The composition may be a home care composition, such as an air care, car care, dishwashing, hard surface cleaning and/or treatment, and other cleaning for consumer or institutional use. 
     The composition may be in any suitable form. For example, the composition may be in the form of a liquid composition, a granular composition, a single-compartment pouch, a multi-compartment pouch, a dissolvable sheet, a pastille or bead, a fibrous article, a tablet, a bar, a flake, a dryer sheet, or a mixture thereof. The composition can be selected from a liquid, solid, or combination thereof. Preferably, the composition is a liquid. The liquid may be encapsulated by water-soluble film to form a unit dose article, such as a pouch. 
     The composition may be in the form of a liquid. The liquid composition may include from about 30%, or from about 40%, or from about 50%, to about 99%, or to about 95%, or to about 90%, or to about 75%, or to about 70%, or to about 60%, by weight of the composition, of water. The liquid composition may be a liquid laundry detergent, a liquid fabric conditioner, a liquid dish detergent, a hair shampoo, a hair conditioner, or a mixture thereof. Preferably, the liquid composition is selected from a liquid laundry detergent, a liquid fabric enhancer, or combinations thereof. The liquid may be packaged in an aerosol can or other spray bottle. 
     The composition may be in the form of a solid. The solid composition may be a powdered or granular composition. Such compositions may be agglomerated or spray-dried. Such composition may include a plurality of granules or particles, at least some of which include comprise different compositions. The composition may be a powdered or granular cleaning composition, which may include a bleaching agent. The composition may be in the form of a bead or pastille, which may be pastilled from a liquid melt. The composition may be an extruded product. 
     The composition may be in the form of a unitized dose article, such as a tablet, a pouch, a sheet, or a fibrous article. Such pouches typically include a water-soluble film, such as a polyvinyl alcohol water-soluble film, that at least partially encapsulates a composition. Suitable films are available from MonoSol, LLC (Indiana, USA). The composition can be encapsulated in a single or multi-compartment pouch. A multi-compartment pouch may have at least two, at least three, or at least four compartments. A multi-compartmented pouch may include compartments that are side-by-side and/or superposed. The composition contained in the pouch or compartments thereof may be liquid, solid (such as powders), or combinations thereof. Pouched compositions may have relatively low amounts of water, for example less than about 20%, or less than about 15%, or less than about 12%, or less than about 10%, or less than about 8%, by weight of the detergent composition, of water. 
     The composition may have a viscosity of from 1 to 1500 centipoises (1-1500 mPa*s), preferably from 100 to 1000 centipoises (100-1000 mPa*s), or more preferably from 200 to 500 centipoises (200-500 mPa*s) at 20 s −1  and 21° C. Compositions having such viscosities are convenient to use without being too thick or thin. 
     Encapsulates 
     The present disclosure relates to encapsulates. The consumer product compositions of the present disclosure comprise encapsulates. As more than one encapsulate is typically present, the compositions may be described as comprising a plurality or population of encapsulates. 
     The composition may comprise from about 0.05% to about 20%, or from about 0.05% to about 10%, or from about 0.1% to about 5%, or from about 0.2% to about 2%, by weight of the composition, of encapsulates. The composition may comprise a sufficient amount of encapsulates to provide from about 0.05% to about 10%, or from about 0.1% to about 5%, or from about 0.1% to about 2%, by weight of the composition, of perfume to the composition. When discussing herein the amount or weight percentage of the encapsulates, it is meant the sum of the shell material and the core material. 
     The encapsulates may have a volume weighted median encapsulate size from about 0.5 microns to about 100 microns, or even 10 to 100 microns, preferably from about 1 micron to about 60 microns, or even 10 microns to 50 microns, or even 20 microns to 45 microns, or alternatively 20 microns to 60 microns. 
     Core 
     The encapsulates of the present disclosure may comprise a core. The core may be surrounded by a shell. The core may comprise a perfume. The perfume may comprise a single perfume raw material or a mixture of perfume raw materials. 
     The term “perfume raw material” (or “PRM”) as used herein refers to compounds having a molecular weight of at least about 100 g/mol and which are useful in imparting an odor, fragrance, essence, or scent, either alone or with other perfume raw materials. Typical PRMs comprise inter alia alcohols, ketones, aldehydes, esters, ethers, nitrites and alkenes, such as terpene. A listing of common PRMs can be found in various reference sources, for example, “Perfume and Flavor Chemicals”, Vols. I and II; Steffen Arctander Allured Pub. Co. (1994) and “Perfumes: Art, Science and Technology”, Miller, P. M. and Lamparsky, D., Blackie Academic and Professional (1994). 
     The PRMs may be characterized by their boiling points (B.P.) measured at the normal pressure (760 mm Hg), and their octanol/water partitioning coefficient (P), which may be described in terms of logP, determined according to the test method below. Based on these characteristics, the PRMs may be categorized as Quadrant I, Quadrant II, Quadrant III, or Quadrant IV perfumes, as described in more detail below. A perfume having a variety of PRMs from different quadrants may be desirable, for example, to provide fragrance benefits at different touchpoints during normal usage. 
     The perfume raw materials may comprise a perfume raw material selected from the group consisting of perfume raw materials having a boiling point (B.P.) lower than about 250° C. and a ClogP lower than about 3, perfume raw materials having a B.P. of greater than about 250° C. and a ClogP of greater than about 3, perfume raw materials having a B.P. of greater than about 250° C. and a ClogP lower than about 3, perfume raw materials having a B.P. lower than about 250° C. and a ClogP greater than about 3 and mixtures thereof. Perfume raw materials having a boiling point B.P. lower than about 250° C. and a ClogP lower than about 3 are known as Quadrant I perfume raw materials. Quadrant I perfume raw materials are preferably limited to less than 30% of the perfume composition. Perfume raw materials having a B.P. of greater than about 250° C. and a ClogP of greater than about 3 are known as Quadrant IV perfume raw materials, perfume raw materials having a B.P. of greater than about 250° C. and a ClogP lower than about 3 are known as Quadrant II perfume raw materials, perfume raw materials having a B.P. lower than about 250° C. and a ClogP greater than about 3 are known as a Quadrant III perfume raw materials. Suitable Quadrant I, II, III and IV perfume raw materials are disclosed in U.S. Pat. No. 6,869,923 B1. 
     The perfume in the core of the encapsulates may comprise perfume raw materials capable of forming an acid. For example, aldehydes (and correspondingly, also acetals) have a tendency to form carboxylic acids in the presence of atmospheric oxygen; esters (and correspondingly, also lactones) can saponify, thereby forming carboxyl groups. Despite the formulation challenges associated with these acid-forming materials, they remain desirable to formulate into product due to the pleasing aesthetics that they may provide. 
     The perfume of the core may be characterized by an acid value. The acid value is effectively a measurement of the amount of free carboxylic acids present in the perfume prior to encapsulation. The perfume may be characterized by an acid value of greater than 5.0 mg/KOH immediately before encapsulation, as determined by the Acid Value Determination method provided in the test methods section below. The perfume may be characterized by an acid value of greater than 5.25, or greater than 5.50, or greater than 5.75, or greater than 6.0 mg/KOH immediately before encapsulation. The perfume may be characterized by an acid value of from about 5.0 to about 25, or from about 5.0 to about 20, or from about 5.5 to about 20, or from about 6 to about 20, or from about 8 to about 20, or from about 10 to about 20, or from about 12 to about 20, or from about 15 to about 20 mg/KOH immediately before encapsulation. 
     Perfume raw materials capable of forming an acid may include materials that include aldehyde, acetal, ester, and/or lactone moieties. The perfume of the present disclosure may comprise from about 30% to about 75%, or from about 35% to about 70%, or from about 40 to about 60%, by weight of the total perfume in the core immediately after encapsulate formation, of perfume raw materials that comprise aldehyde moieties, acetal moieties, ester moieties, lactone moieties, or mixtures thereof. 
     The encapsulated perfume of the present disclosure may comprise aldehyde compounds, ester compounds, or mixtures thereof. The perfume of the present disclosure may comprise from about 30% to about 75%, or from about 35% to about 70%, or from about 40 to about 60%, by weight of the total perfume in the core immediately after encapsulate formation, of aldehyde compounds, ester compounds, or mixtures thereof. The perfume of the present disclosure may comprise from about 2% to about 30%, or from about 3% to about 25%, or from about 4% to about 20%, or from about 4% to about 15%, by weight of the total perfume in the core immediately after encapsulate formation, of aldehyde compounds. The perfume of the present disclosure may comprise from about 10% to about 60%, or from about 20% to about 50%, or from about 30% to about 50%, by weight of the total perfume in the core immediately after encapsulate formation, of ester compounds.

     It is known that not all aldehydes are prone to oxidation into acids in the same manner, just as it is known that not all esters are equally likely to transform into acids. Thus, perfume mixtures that may facially have similar amounts of aldehydes and/or esters may be characterized by different acid values, depending on the particular aldehydes and/or esters present in each perfume mixture. 
     For example, a compound&#39;s likelihood of oxidation may relate to the compound&#39;s ionization potential. Without wishing to be bound by theory, it is believed that the lower a compound&#39;s ionization potential, the more likely it is that oxidation will occur. The perfume of the core may include perfume raw materials that are characterized by relatively low ionization potentials, for example equal to or less than about 8.5, or equal to or less than about 8.0, or equal to or less than about 7.5. The perfume of the core may include a certain minimum of such perfume raw materials, such as at least about 10%, or at least about 20%, or at least about 30%, or at least about 40%, or at least about 50%, by weight of the perfume of the core. Higher amounts of such materials may provide higher acid values for the perfume, and the encapsulates of the present disclosure are believed to be particularly well-suited for encapsulating such perfumes. 
     Certain esters may also be more likely to hydrolyze under certain conditions than others. Those esters that are more likely to undergo acidic hydrolysis may lead to more carboxylic acid formation and therefore greater acid values. Furthermore, without wishing to be bound by theory, it is believed that esters that are more likely to undergo basic hydrolysis may contribute to encapsulate leakage, as the salts formed upon hydrolysis may enter an aqueous phase and be more likely to leave the core of an encapsulate. 
     Differences in ionization potentials and/or hydrolysis rates may be affected by a perfume raw material&#39;s structure. For example, steric hindrance near an ester moiety may result in lower-than-expected hydrolysis rates.

     TEST METHODS 
     Extraction of encapsulates from finished products 
     Except where otherwise specified herein, the preferred method to isolate encapsulates from finished products is based on the fact that the density of most such encapsulates is different from that of water. The finished product is mixed with water in order to dilute and/or release the encapsulates. The diluted product suspension is centrifuged to speed up the separation of the encapsulates. Such encapsulates tend to float or sink in the diluted solution/dispersion of the finished product. Using a pipette or spatula, the top and bottom layers of this suspension are removed and undergo further rounds of dilution and centrifugation to separate and enrich the encapsulates. The encapsulates are observed using an optical microscope equipped with crossed-polarized filters or differential interference contrast (DIC), at total magnifications of 100× and 400×. The microscopic observations provide an initial indication of the presence, size, quality and aggregation of the encapsulates. 
     For extraction of encapsulates from a liquid fabric enhancer finished product conduct the following procedure:
         1. Place three aliquots of approximately 20 ml of liquid fabric enhancer into three separate 50 ml centrifuge tubes and dilute each aliquot 1:1 with DI water (e.g. 20 ml fabric enhancer +20 ml DI water), mix each aliquot well and centrifuge each aliquot for 30 minutes at approximately 10000×g.   2. After centrifuging per Step 1, discard the bottom water layer (around 10 ml) in each 50 ml centrifuge tube then add 10 ml of DI water to each 50 ml centrifuge tube.   3. For each aliquot, repeat the process of centrifuging, removing the bottom water layer and then adding 10 ml of DI water to each 50 ml centrifuge tube two additional times.   4. Remove the top layer with a spatula or a pipette, and   5. Transfer this top layer into a 1.8 ml centrifuge tube and centrifuge for 5 minutes at approximately 20000×g.   6. Remove the top layer with a spatula and transfer into a new 1.8 ml centrifuge tube and add DI water until the tube is completely filled, then centrifuge for 5 minutes at approximately 20000×g.   7. Remove the bottom layer with a fine pipette and add DI water until tube is completely filled and centrifuge for 5 minutes at approximately 20000×g.   8. Repeat step 7 for an additional 5 times (6 times in total).       

     If both a top layer and a bottom layer of enriched encapsulates appear in the above described step 1, then, immediately move to step 3 (i.e., omit step 2) and proceed steps with steps 4 through 8. Once those steps have been completed, also remove the bottom layer from the 50 ml centrifuge tube from step 1, using a spatula or/and a pipette. Transfer the bottom layer into a 1.8 ml centrifuge tube and centrifuge 5 min at approximately 20000×g. Remove the bottom layer in a new tube and add DI water until the tube is completely filled then centrifuge for 5 minutes approximately 20000×g. Remove the top layer (water) and add DI water again until the tube is full. Repeat this another 5 times (6 times in total). Recombine the encapsulate enriched and isolated top and bottom layers back together. 
     If the fabric enhancer has a white color or is difficult to distinguish the encapsulate enriched layers add 4 drops of dye (such as Liquitint Blue JH 5% premix from Milliken &amp; Company, Spartanburg, S.C., USA) into the centrifuge tube of step 1 and proceed with the isolation as described. 
     For extraction of encapsulates from solid finished products that disperse readily in water, mix 1 L of DI water with 20 g of the finished product (e.g. detergent foams, films, gels and granules; or water-soluble polymers; soap flakes and soap bars; and other readily water-soluble matrices such as salts, sugars, clays, and starches). When extracting encapsulates from finished products which do not disperse readily in water, such as waxes, dryer sheets, dryer bars, and greasy materials, it may be necessary to add detergents, agitation, and/or gently heat the product and diluent in order to release the encapsulates from the matrix. The use of organic solvents or drying out of the encapsulates should be avoided during the extraction steps as these actions may damage the encapsulates during this phase. 
     For extraction of encapsulates from liquid finished products which are not fabric softeners or fabric enhancers (e.g., liquid laundry detergents, liquid dish washing detergents, liquid hand soaps, lotions, shampoos, conditioners, and hair dyes), mix 20 ml of finished product with 20 ml of DI water. If necessary, NaCl (e.g., 100-200 g NaCl) can be added to the diluted suspension in order to increase the density of the solution and facilitate the encapsulates floating to the top layer. If the product has a white color which makes it difficult to distinguish the layers of encapsulates formed during centrifugation, a water-soluble dye can be added to the diluent to provide visual contrast. 
     The water and product mixture is subjected to sequential rounds of centrifugation, involving removal of the top and bottom layers, re-suspension of those layers in new diluent, followed by further centrifugation, isolation and re-suspension. Each round of centrifugation occurs in tubes of 1.5 to 50 ml in volume, using centrifugal forces of up to 20,000×g, for periods of 5 to 30 minutes. At least six rounds of centrifugation are typically needed to extract and clean sufficient encapsulates for testing. For example, the initial round of centrifugation may be conducted in 50 ml tubes spun at 10,000×g for 30 mins, followed by five more rounds of centrifugation where the material from the top and bottom layers is resuspended separately in fresh diluent in 1.8 ml tubes and spun at 20,000×g for 5 mins per round. 
     If encapsulates are observed microscopically in both the top and bottom layers, then the encapsulates from these two layers are recombined after the final centrifugation step, to create a single sample containing all the delivery encapsulates extracted from that product. The extracted encapsulates should be analyzed as soon as possible but may be stored as a suspension in DI water for up to 14 days before they are analyzed. 
     One skilled in the art will recognize that various other protocols may be constructed for the extraction and isolation of encapsulates from finished products and will recognize that such methods require validation via a comparison of the resulting measured values, as measured before and after the encapsulates&#39; addition to and extraction from finished product. 
     Viscosity 
     Viscosity of liquid finished product is measured using an AR 550 rheometer/viscometer from TA instruments (New Castle, Del., USA), using parallel steel plates of 40 mm diameter and a gap size of 500 μm. The high shear viscosity at 20 s −1  and low shear viscosity at 0.05 s −1  is obtained from a logarithmic shear rate sweep from 0.1 s −1  to 25 s −1  in 3 minutes time at 21° C.

     The encapsulate shell thickness is measured in nanometers on 50 encapsulates using freeze-fracture cryo-scanning electron microscopy (FF cryoSEM), at magnifications of between 50,000× and 150,000×. Samples are prepared by flash freezing small volumes of a suspension of encapsulates or finished product. Flash freezing can be achieved by plunging into liquid ethane, or through the use of a device such as a High Pressure Freezer Model 706802 EM Pact, (Leica Microsystems, Wetzlar, Germany). Frozen samples are fractured while at −120 ° C., then cooled to below −160° C. and lightly sputter-coated with gold/palladium. These steps can be achieved using cryo preparation devices such as those from Gatan Inc., (Pleasanton, Calif., USA). The frozen, fractured and coated sample is then transferred at −170° C. or lower, to a suitable cryoSEM microscope, such as the Hitachi S-5200 SEM/STEM (Hitachi High Technologies, Tokyo, Japan). In the Hitachi S-5200, imaging is performed with 3.0 KV accelerating voltage and 5 μA-20 μA tip emission current. 
     Images are acquired of the fractured shell in cross-sectional view from 50 benefit delivery encapsulates selected in a random manner which is unbiased by their size, so as to create a representative sample of the distribution of encapsulate sizes present. The shell thickness of each of the 50 encapsulates is measured using the calibrated microscope software, by drawing a measurement line perpendicular to the outer surface of the encapsulate shell. The 50 independent shell thickness measurements are recorded and used to calculate the mean thickness, and the percentage of the encapsulates having a shell thickness within the claimed range. 
     Perfume and Perfume Raw Materials (PRMs) 
     To determine the identity and to quantify the weight of perfume, perfume ingredients, or Perfume Raw Materials (PRMs), encapsulated within the delivery agent encapsulates, Gas Chromatography with Mass Spectroscopy/Flame Ionization Detector (GC-MS/FID) is employed. Suitable equipment includes: Agilent Technologies G1530A GC/FID; Hewlett Packer Mass Selective Device 5973; and 5%-Phenyl-methylpolysiloxane Column J&amp;W DB-5 (30 m length×0.25 mm internal diameter×0.25 μm film thickness). Approximately 3 g of the finished product or suspension of delivery encapsulates, is weighed and the weight recorded, then the sample is diluted with 30 mL of DI water and filtered through a 5.0 μm pore size nitrocellulose filter membrane. Material captured on the filter is solubilized in 5 mL of ISTD solution (25.0 mg/L tetradecane in anhydrous alcohol) and heated at 60° C. for 30 minutes. The cooled solution is filtered through 0.45 μm pore size PTFE syringe filter and analyzed via GC-MS/FID. Three known perfume oils are used as comparison reference standards. Data Analysis involves summing the total area counts minus the ISTD area counts and calculating an average Response Factor (RF) for the 3 standard perfumes. Then the Response Factor and total area counts for the product encapsulated perfumes are used along with the weight of the sample, to determine the total weight percent for each PRM in the encapsulated perfume. PRMs are identified from the mass spectrometry peaks. 
     Test Method for Determining logP 
     The value of the log of the Octanol/Water Partition Coefficient (logP) is computed for each PRM in the perfume mixture being tested. The logP of an individual PRM is calculated using the Consensus logP Computational Model, version 14.02 (Linux) available from Advanced Chemistry Development Inc. (ACD/Labs) (Toronto, Canada) to provide the unitless logP value. The ACD/Labs&#39; Consensus logP Computational Model is part of the ACD/Labs model suite. 
     Volume Weighted Median Encapsulate Size 
     Encapsulate size is measured using an Accusizer 780A, made by Encapsulate Sizing Systems, Santa Barbara, Calif. The instrument is calibrated from 0 to 300 μ using Duke encapsulate size standards. Samples for encapsulate size evaluation are prepared by diluting about 1 g emulsion, if the volume weighted median encapsulate size of the emulsion is to be determined, or 1 g of capsule slurry, if the finished capsule volume weighted median encapsulate size is to be determined, in about 5 g of de-ionized water and further diluting about 1 g of this solution in about 25 g of water. 
     About 1 g of the most dilute sample is added to the Accusizer and the testing initiated, using the autodilution feature. The Accusizer should be reading in excess of 9200 counts/second. If the counts are less than 9200 additional sample should be added. The Accusizer will dilute the test sample until 9200 counts/second and initiate the evaluation. After 2 minutes of testing the Accusizer will display the results, including volume-weighted median size. 
     The broadness index can be calculated by determining the encapsulate size at which 95% of the cumulative encapsulate volume is exceeded (95% size), the encapsulate size at which 5% of the cumulative encapsulate volume is exceeded (5% size), and the median volume-weighted encapsulate size (50% size-50% of the encapsulate volume both above and below this size). Broadness Index (5) =((95% size)−(5% size))/50% size). 
     Acid Value Determination 
     To determine acid value of a perfume material, the following method is followed, which is based on DIN EN ISO 660: 2009-10. 
     In a 200-mL tri-pour cup, provide approximately 5 g of perfume to be tested; record the exact weight of perfume. To the perfume sample, add 100 mL of a solvent mixture formed from equal volumes of ethanol and ethyl ether (e.g., prepare a 1 L mixture made from 500 mL of each). Add 0.3 mL of phenolphthalein solution (formed from 1.0 g of phenolphthalein in 100 mL of ethanol). Add a stir bar, place on stir plate, and begin stirring the sample. 
     Add a pH probe to the sample and wait until the pH stabilizes. Neutralize the sample solution by slowly adding potassium hydroxide (0.1M KOH) via titration until the sample reaches a pH of 7. 
     At this point, record the initial volume of potassium hydroxide as the initial volume. Add 0.1M potassium hydroxide until a single drop produces a pink color change that persists for at least 15 seconds. Record the volume of potassium hydroxide as the final volume. Determine the total volume of potassium hydroxide added by determining the difference between the initial volume and the final volume (e.g., the volume of KOH solution added from when pH=7 to when the sample turns a persistent pink). 
     Determine the acid value (reported as mg of KOH/g of perfume) with the following equation:

     To note, 5 g sample of perfume is just a guide; it may be useful to use greater volumes for perfumes that have relatively low acid values, and lesser volumes for perfumes that have relatively high acid values. Depending on the outcome of the initial titration, the sample weight may be increased or decreased for a repeat of the test. Additionally, although the present procedure uses 0.1M KOH, greater molarities may be useful for perfumes that have relatively high acid values. The following table may be used as a rough guide.

     Determining Perfume Leakage 
     To determine perfume leakage, a liquid detergent with perfume encapsulates is prepared and stored (e.g., one week at 35° C.), and then compared to a reference sample of liquid detergent having an equal level of total perfume (e.g., 1 wt %), though unencapsulated. 
     To prepare the Internal Standard Solution, weigh 70 mg of tonalid, add 20 mL hexane p.a., and mix. Add 200 μL of this mixture to 20 mL hexane p.a. and mix to homogenize, forming the Internal Standard Solution. 
     To extract the perfume from liquid phase of the test sample or the reference sample, 2 grams of the detergent sample and 2 mL of the Internal Standard Solution are placed into an extraction vessel. Free perfume is extracted from the detergent sample by gently inverting the extraction vessel manually twenty times. A spoon tip of sodium sulphate is added to the extraction vessel. A separation of layers should occur. 
     To collect Gas Chromatograph data, after the separation into layers, immediately transfer the hexane layer into a Gas Chromatograph auto sampler vial and cap the vial. Inject 1.5 μL splitless into the Gas Chromatograph injection port. Run Gas Chromatographic Mass Spectrometric analysis (Gas Chromatographic separation on Durawax-4 [60 m, 0.32 mm ID, 0.25 μm Film] 40° C./4° C./min/230° C./20′). 
     The perfume leakage from the encapsulates is calculated per Perfume Raw Material according to the following calculation:

     Total leakage of a perfume is the sum of the perfume leakage from capsules per individual PRM. 
     To determine perfume retention (e.g., percentage of perfume that remains in the encapsulate), the “% perfume leakage” is subtracted from 100.

     Example 2 
     Process of Making Encapsulates 
     Polyacrylate perfume capsules are made as follows: a first oil phase, consisting of 37.5 g perfume, 0.2 g tert-butylamino ethyl methacrylate, 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 perfume oil, 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 is mixed at 500 rpm 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 is 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 Selvol 540 polyvinylalcohol (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, was prepared and mixed until the 4,4′-azobix[5-cyanovaleric acid] dissolves. 
     Once the oil phase temperature decreases 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 for 60 minutes). 
     The temperature is increased to 75° C. in 30 minutes, is held at 75° C. for 4 hours, is increased to 95° C. in 30 minutes, and is held at 95° C. for 6 hours. 
     Example 3 
     Encapsulate Leakage 
     To test for leakage, various perfumes are encapsulated in shells that include polyacrylate materials (including CN975 from Sartomer, Inc.) generally according to the encapsulation process described in Example 2. In addition to the perfumes provided below, the cores of the encapsulates comprise from about 30% to about 45% of a partitioning modifier (i.e., isopropyl myristate). 
     The encapsulates are added to a liquid detergent composition that is otherwise free of perfume. The encapsulates are added at a level to provide a total of 1% perfume, by weight of the detergent composition. The formulation of the liquid detergent is provided below in Table 2.

     The liquid detergent samples are aged for one week at 35° C. After storage, the samples are analyzed for perfume leakage via hexane extraction as detailed in the test method section above. Leakage is measured versus a reference sample containing 1%, by weight of the reference sample, of unencapsulated perfume of the same identity. 
     The perfumes tested are some of those provided in Example 1, Table 1 above. Trials 1-5 show encapsulates comprising comparative perfumes, which are characterized by acid values less than 5.0 mg KOH/g. Trials 6-9 show encapsulates comprising perfumes according to the present disclosure, which are characterized by acid values of greater than 5.0 mg KOH/g. 
     Perfume leakage results are shown in Table 3.  FIG. 1  shows a graph of acid values versus perfume retention, measured as the percentage of perfume remaining in the encapsulates.

     According to the results in Table 3 and  FIG. 1 , perfumes encapsulates that include polyacrylate materials in the encapsulate shell show relatively little leakage upon storage in a detergent product, even when the perfume is characterized by an acid value of greater than 5.0 mg KOH/g. 
     Although tested under different temperature and timings, this trend stands in stark contrast from the trend disclosed in WO2017/148504, which indicates that very little perfume is retained in a capsule when the perfume is characterized by an acid value of greater than 5 mg KOH/g of perfume. Without wishing to be bound by theory, it is believed that selection of the encapsulate wall material (here, a polyacrylate material) contributes to the relative stability of the encapsulates of the present disclosure. 
     The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as “40 mm” is intended to mean “about 40 mm.”
