Description

The present application relates to benefit agent-containing delivery particles comprising a core and a shell enclosing the core, compositions comprising such particles, and processes for making and using such particles and compositions.

Benefit agents such as fragrances, silicones, waxes, flavors, vitamins, and fabric softeners are expensive and/or expensive in consumer products such as personal care, cleaning, and fabric care compositions. When used in concentrations, they are generally less effective. As a result, it is desirable to maximize the efficiency of such benefit agents. One way of achieving such goals is to improve the efficiency of delivery of such beneficial agents. Unfortunately, benefit agents may be compromised due to their physical or chemical properties, or may be incompatible with other compositional components or the site being treated. Increasing delivery efficiency is difficult. In order to improve such delivery efficiency, beneficial agents are encapsulated.

It is desirable for benefit agent-containing delivery particles having shells comprising polyacrylate to provide perfume benefits at all points of consumer contact. For example, it is desirable for such particles to provide a perfume benefit to fabrics treated with such particles when the fabrics are still wet from such treatment and after such fabrics have dried. Unfortunately, such particles leak benefit agent over time, possibly through diffusion. Therefore, fabric odor is reduced. For example, by increasing the shell strength of the particles, wet and/or dry fabric odor can also be reduced when such leakage is minimized. This problem is particularly pronounced in fabric treatment products such as liquid fabric enhancers, liquid laundry detergents, unit dose laundry detergents, and granular/powder laundry detergents containing such particles. What is needed, therefore, are particles that exhibit reduced leakage of benefit agent but provide desired odor profiles, specifically improved pre- and post-rub benefits on wet and dry fabrics. is.

Applicants have now recognized that multi-component issues are the source of the problems that lead to the shell strength versus benefit agent release dilemma in benefit agent delivery systems. Since the colloid and capsule shell polymer both form a unitary delivery system and the polymerization process is influenced by the benefit agent solvent system, this multi-component issue is the type of colloid, the monomer building blocks for the capsule wall, and the benefit agent. The drug-solvent system is the root. The level, type, and molecular weight of the colloid, such as polyvinyl alcohol, used in combination with the capsule shell polymer formed during the particle fabrication process can affect the effectiveness of the delivery system. This is especially true when such delivery agent polymer shells are also partially constructed from monomers with multiple cross-linking sites/moieties such as acrylate moieties. In general, the molecular weight and cross-linking of the non-colloidal portion of the delivery system are difficult to control. Surprisingly, Applicants have recognized that such control can be obtained if not only the shell material, but also the type of colloid and the encapsulated benefit agent solvent system are judiciously selected. The benefit agent solvent system also contributes to the resulting molecular weight and cross-linking in the resulting polymer in the non-colloidal portion of the delivery system. While not wishing to be bound by theory, Applicants therefore believe that the colloid type, level, and molecular weight of the delivery system selected in combination with the resulting shell polymer, and the particle size of the delivery system, will affect the thought to influence the odor profile (intensity or character) that can be

While such judicious selection will provide the desired benefits, benefit agent-containing delivery particles are typically supplied as slurries and the use of polyvinyl alcohol as a colloid reduces the stability of the particle-containing slurry. may cause Applicants have discovered that the cause of this problem is that some of the polyvinyl alcohol used to make the particles is found in the slurry as free polyvinyl alcohol. In essence, this free polyvinyl alcohol is not incorporated into the shell encapsulating the benefit agent. Such free polyvinyl alcohol results in depleted agglomeration of benefit agent-containing delivery particles, which destabilizes the slurry. Such depleted flocculation is exacerbated by the presence of salt. In order to achieve an acceptable level of stability, the level of free polyvinyl alcohol can be reduced by appropriately selecting the level of polyvinyl alcohol used in making the benefit agent-containing delivery particles. can be judiciously selected, a more efficient process of making benefit agent-containing delivery particles can be used, and/or the slurry can be purified to remove free polyvinyl alcohol. Preferably, salt levels are also minimized. As a result, the benefit agent can be dispensed as a slurry and exhibits reduced leakage of the benefit agent, yet provides the desired odor profile, specifically improved pre- and post-rub benefits on wet and dry fabrics. Contained delivery particles can be made and used. Provided herein are processes for making and using such benefit agent-containing delivery particles, as well as compositions comprising the same.

The present application relates to benefit agent-containing delivery particles comprising a core and a shell enclosing the core, compositions comprising such particles, and processes for making and using such particles and compositions.

(1) Extraction of Benefit Agent-Containing Delivery Particles from the Final Product Unless otherwise indicated herein, the preferred method of isolating benefit agent-containing delivery particles from the final product is that the majority of such particles have a density of Based on the fact that the density of water is different. The final product is mixed with water to dilute and/or release the particles. The diluted product suspension is centrifuged to accelerate particle separation. Such particles tend to float or sink in the dilute solution/dispersion of the final product. Using a pipette or spatula, the top and bottom layers of this suspension are removed and subjected to further rounds of dilution and centrifugation to separate and enrich the particles. Particles are observed using a light microscope equipped with cross-polarized filters or differential interference contrast (DIC) at magnifications ranging from 100× to at least 400×. Microscopic observation provides an early indication of the presence, size, and aggregation of delivery particles.

To extract the delivery particles from the liquid fabric enhancer, the final product undergoes the following procedure:
1. Place three aliquots of approximately 20 mL liquid fabric enhancer separately into three 50 mL centrifuge tubes and dilute each with 1:1 aliquot:deionized water (e.g., 20 mL fabric enhancer + 20 mL deionized water). , mix each aliquot well and centrifuge each aliquot for 30 minutes at approximately 10,000 xg.
2. After step 1 centrifugation, discard the bottom aqueous layer (approximately 10 mL) in each 50 mL centrifuge tube, then add 10 mL of deionized water to each 50 mL centrifuge tube.
3. For each aliquot, the process of centrifugation, removal of the bottom aqueous layer, and subsequent addition of 10 mL of deionized water to each 50 mL centrifuge tube is repeated two more times.
4. Remove the top layer with a spatula or pipette.
5. Transfer this top layer to a 1.8 mL centrifuge tube and centrifuge at approximately 20,000 xg for 5 minutes.
6. Remove the top layer with a spatula, transfer to a new 1.8 mL centrifuge tube, add deionized water until the tube is completely filled, then centrifuge at approximately 20,000 xg for 5 minutes.
7. Remove the bottom layer with a fine pipette, add deionized water until the tube is completely filled, and centrifuge at approximately 20,000 xg for 5 minutes.
8. Repeat step 7 5 more times (6 times total).

If both the top and bottom layers appear to be rich in particles in step 1 above, proceed immediately to step 3 (ie skip step 2) and proceed to steps 4-8. Once those steps are complete, as in step 1, remove the bottom layer from the 50 mL centrifuge tube using a spatula and/or pipette. Transfer the bottom layer to a 1.8 mL centrifuge tube and centrifuge at approximately 20000 xg for 5 minutes. Remove the bottom layer in the new tube, add deionized water until the tube is completely filled, then centrifuge at approximately 20,000 xg for 5 minutes. Remove the top layer (water) and add deionized water again until the tube is full. Repeat this 5 more times (6 total). The particle-rich isolated top and bottom layers are returned and combined together.

If the fabric enhancer is white or the particle-rich layer is difficult to distinguish, add a dye (such as Liquitint Blue JH 5% premix from Milliken & Company, Spartanburg, South Carolina, USA) to the centrifuge tube from step 1. and proceed with isolation as described.

To extract delivery particles from a solid final product that readily disperses in water, 1 L of deionized water was added to 20 g of the final product (e.g., detergent foams, films, gels and granules; or water-soluble polymers; soap flakes and soap bars and other water-soluble matrices such as salts, sugars, clays, and starches). adding a detergent to the product and diluent to release the particles from the matrix when extracting the particles from a final product that does not readily disperse in water such as waxes, dryer sheets, dryer bars, and greasy materials; Stirring and/or gentle heating may be necessary. These manipulations can damage the delivery particles during this step, so the use of organic solvents or drying of the particles must be avoided during the extraction process.

For extraction of delivery particles from liquid end products that are not fabric softeners or fabric enhancers (e.g., liquid laundry detergents, liquid dishwashing detergents, liquid hand soaps, lotions, shampoos, conditioners, and hair dyes), 20 mL Mix the final product with 20 mL of deionized water. Optionally, NaCl (eg, 100-200 g of NaCl) may be added to the diluted suspension to increase the density of the solution and promote floating of the particles to the top layer. If the product has a white color that makes it difficult to distinguish the layers of particles formed during centrifugation, a water-soluble dye may be added to the diluent to provide a visual contrast. The water and product mixture undergoes successive rounds of centrifugation, with removal of the top and bottom layers, resuspension of those layers in fresh diluent, and further centrifugation, isolation, and resuspension. Continue. Each round of centrifugation occurs in 1.5-50 mL tubes using a centrifugal force of up to 20,000×g for 5-30 minutes. At least six rounds of centrifugation are typically required to extract and clean enough particles for testing. For example, a first round of centrifugation may be performed in a 50 mL tube spun at 10,000 xg for 30 minutes, followed by 5 more rounds of centrifugation, wherein material from the top and bottom layers is 1. Resuspend separately in fresh diluent in 8 mL tubes and spin at 20,000 xg for 5 minutes per round.

If delivery particles were observed microscopically in both the top and bottom layers, the particles from these two layers were recombined after the final centrifugation step to yield a single sample containing all of the delivery particles extracted from the product. produce. Extracted particles should be analyzed as soon as possible, but may be stored as deionized water suspensions for up to 14 days prior to analysis.

Those skilled in the art will recognize that various other protocols can be constructed for extracting and isolating the delivery particles from the final product, and such methods may include measurements before and after addition and extraction of the particles to the final product. You will recognize the need for validation through comparison of measurements obtained by

(2) Particle size (diameter)
A drop of the particle suspension or final product is placed on a glass microscope slide and allowed to dry under ambient conditions for several minutes to remove water, resulting in a single layer of low density isolated particles on the dry slide. Adjust the concentration of particles in the suspension to obtain a suitable particle density on the slide as needed. Slides are placed on the specimen stage of an equipped light microscope and examined at 100x or 400x overall magnification. Images are acquired and calibrated to accurately measure particle diameter. Three replicate slides are prepared and analyzed.

For particle size measurements, at least 50 benefit agent delivery particles on each slide are selected for measurement so as to create a representative sample of the distribution of particle sizes present, without prejudice due to their size. This can be accomplished by examining fields selected randomly or according to a predefined grid pattern and measuring the diameter of all delivery particles present in each field examined. Delivery particles that are clearly not spherical, deflated, leaky or appear damaged are not suitable for measurement and are excluded from the selection process and their diameters are not recorded. The diameter of each delivery particle suitable for inspection is measured using a microscope and the value recorded. The recorded particle diameter measurements are used to calculate the percentage of particles having a size within the claimed size range(s), as well as their average size.

(3) Particle Shell Thickness Shell thickness of 50 benefit agent-containing delivery particles using freeze-fracture cryo-scanning electron microscopy (FF cryoSEM) at 50,000X to 150,000X magnification. is measured in nanometers. Samples are prepared by flash freezing a small suspension of particles or the final product. Quick freezing can be achieved by immersion in liquid ethane or by use of a device such as the High Pressure Freezer Model 706802 EM Pact (Leica Microsystems, Wetzlar, Germany). Frozen samples are fractured at -120°C, then cooled to below -160°C and lightly sputter coated with gold/palladium. These processes are manufactured by Gatan Inc. (Pleasanton, Calif., USA). The frozen, cleaved and coated sample is then transferred to a suitable cryoSEM microscope such as a Hitachi S-5200 SEM/STEM (Hitachi High Technologies, Tokyo, Japan) at -170°C or below. On the Hitachi S-5200, imaging is performed at an acceleration voltage of 3.0 KV and a tip emission current of 5-20 μA.

Cross-sections from 50 benefit agent-containing delivery particles selected in a random fashion without prejudice due to their size to create a representative sample of the existing particle size distribution were sectioned. Get an image of the shell. The shell thickness of each of the 50 particles is measured using calibrated microscope software by drawing a measurement line perpendicular to the outer surface of the particle shell. Fifty individual shell thickness measurements are recorded and used to calculate the average thickness and the percentage of particles having a shell thickness within the claimed range.

(4) Beneficial Agent Leakage Rate The amount of benefit agent leakage from the benefit agent containing delivery particles is determined according to the following method:
a. ) Obtain two 1 g samples of the raw material slurry of benefit agent-containing delivery particles.
b. ) Add 1 g of the raw material slurry of benefit agent-containing delivery particles to 99 g of the product matrix with the particles therein and label the mixture as Sample 1; A second 1 g sample of the raw material particle slurry is immediately used in its undiluted form without contacting the product matrix in step d below and is labeled Sample 2.
c. ) Age the particle-containing product matrix (Sample 1) at 35° C. for 2 weeks in a sealed glass bottle.
d. ) Filtration is used to recover the particles from both samples. After the aging process, the particles in Sample 1 (in the product matrix) are collected. The particles in Sample 2 (the undiluted raw material slurry) are collected at the same time that the aging process is started on Sample 1 .
e. ) Treating the recovered particles with a solvent to extract the benefit agent material from the particles.
f. ) Solvent containing benefit agent extracted from each sample is analyzed via chromatography. The resulting areas of the benefit agent peak under the curve are integrated and these areas are summed to determine the total amount of benefit agent extracted from each sample.
g. ) Determine the percentage of benefit agent leakage by calculating the difference between the value obtained for the total amount of benefit agent extracted from sample 2 minus the value from sample 1, and the benefit agent extracted from sample 2 is expressed as a percentage of the total amount of and represented by the following equation:

(5) Viscosity Using an AR550 rheometer/viscometer from TA instruments (New Castle, DE, USA), using parallel steel plates with a gap size of 40 mm in diameter and 500 μm, the viscosity of the liquid final product to measure. High shear viscosity at 20 s ^-1 and low shear viscosity at 0.05 s ^-1 are obtained from logarithmic shear rate sweeps from 0.1 s ^-1 to 25 s ^-1 for 3 minutes at 21°C.

(6) Perfume and Perfume Raw Material (PRM)
Gas Chromatography with Mass Spectroscopy/Flame Ionization Detector (Gas Chromatography with Mass Spectroscopy/ Gas chromatography with Flame Ionization Detector, GC-MS/FID) is used. Suitable equipment includes an Agilent Technologies G1530A GC/FID; Hewlett Packard Mass Selective Device 5973, and a 5%-phenyl-methylpolysiloxane column J&W DB-5 (30 m long x 0.25 mm internal diameter x 0.25 µm film thickness). is mentioned. Weigh approximately 3 g of the final product or delivery particle suspension, record the weight, then dilute the sample with 30 mL of deionized water and filter through a 5.0 μm pore size nitrocellulose filter membrane. The material trapped on the filter is solubilized with 5 mL of ISTD solution (25.0 mg/L tetradecane in absolute alcohol) and heated at 60° C. for 30 minutes. The cooled solution is filtered through a 0.45 μm pore size PTFE syringe filter and analyzed via GC-MS/FID. Three known perfume oils are used as comparative reference standards. Data analysis included summing the total area counts subtracted from the ISTD area counts and calculating the mean Response Factor (RF) of the three standard perfumes. The response factor and total area count of the perfume-encapsulated product are then used along with the weight of the sample to determine the total weight percent for each PRM in the encapsulated perfume. Identify the PRM from the mass spec peak.

(7) Volume Weighted Average Particle Size Particle size is measured using a static light scattering device such as the Accusizer 780A from Particle Sizing Systems (Santa Barbara Calif.). The instrument is calibrated from 0-300μ using Duke particle size standards. Samples for particle size evaluation were approximately 1 g of emulsion (for determining the volume weighted average particle size of the emulsion), or 1 g of the benefit agent-containing delivery particle slurry (for determining the volume weighted average particle size of the final particles). Prepared by diluting in 5 g of deionized water and further diluting about 1 g of this solution in about 25 g of water.

Using the autodilution function, approximately 1 g of the most diluted sample is added to the Accusizer and the test is started. The Accusizer should read over 9200 counts/sec. If the count is less than 9200, additional sample should be added. The Accusizer dilutes the test sample to 9200 counts/sec and begins the evaluation. Two minutes after testing, the Accusizer displays results including the volume-weighted median diameter.

The particle size exceeded by 95% of the accumulated particle volume (95% diameter), the particle size exceeded by 5% of the accumulated particle volume (5% diameter), and the volume-weighted median particle size (50% diameter - particles above this diameter By determining both the volume and the particle volume below this diameter (50% of the particle volume), the width index can be calculated. Width index (5)=((95% diameter)-(5% diameter)/50% diameter).

(8) Polyvinyl alcohol in the continuous phase based on the total weight of water in the continuous phase and polyvinyl alcohol in the benefit agent containing delivery particles based on the core weight of the benefit agent containing delivery particles Capillary gel permeation chromatography - quadrupole flight Free polyvinyl alcohol levels are measured using time-mass spectrometry.

This method is based on measuring the ion intensity of specific fragment ions produced in an electrospray quadrupole time-of-flight mass spectrometer operated at high collision energy (CE). Specifically, a polyvinyl alcohol polymer molecule can be fragmented at CE 70V to generate a unique marker ion (eg, m/z 131). The ionic strength correlates with the polyvinyl alcohol concentration in the PMC slurry sample solution.

Experimental conditions:
Calibration solution preparation A 5% polyvinyl alcohol stock solution was first diluted with deionized water (Millipore) to give a 0.05% solution, then further two-fold serial dilutions were made to give a concentration range of 0.00078% to 0.05%. get

Sample Solution Preparation Each benefit agent-containing delivery particle slurry solution is first diluted 5-fold or 10-fold with water and then filtered by passing through a 0.45um PVDF membrane filter (PALL Gelman Lab).

Capillary Gel Permeation Chromatography-Mass Spectrometry (“GPC”) Four consecutive 1 mm×150 mm ID TSKGel G5000 or G6000 columns (Tosoh Bioscience, Japan) were run by injecting 5 ul of both calibration standard and sample solutions. GPC system attached to an electrospray quadrupole time-of-flight mass spectrometer (QTOF, Waters (Beverly, Mass.)) with 25 ul/min isocratic flow and 30 min run. Analyze in time. The GPC buffer used is 5 mM ammonium acetate containing 10% acetonitrile. For mass analysis, the first quadrupole was operated in broadband RF-only mode, allowing all ions to pass through the quadrupole, fragmented with the CE70V of the second quadrupole, and transferred to the TOF mass spectrometer. analyzed by The scanned mass range is 50-3000 Da.

Data Acquisition, Processing, and Analysis The QTOF mass spectrometer uses MassLynx (Waters) for data acquisition and data processing. The peak intensity of the major polyvinyl alcohol fragment ion m/z 131 is measured and averaged from two replicate CapGPC-QTOF experiments. The polyvinyl alcohol percent concentration in each sample is calculated against a polyvinyl alcohol standard calibration curve. A good linear range is obtained under the current measurement conditions.

The bound polyvinyl alcohol level is calculated using the following equation.
% bound polyvinyl alcohol = total % polyvinyl alcohol added to slurry - % free polyvinyl alcohol

(9) Determination of Degree of Hydrolysis of Polyvinyl Alcohol Degree of hydrolysis, defined as percent hydrolysis, means mol % hydrolysis of polyvinyl alcohol determined as follows. This measurement measures the number of acetate groups substituted for hydroxyl groups during alcoholysis.

The degree of hydrolysis of polyvinyl alcohol is determined by refluxing in a strong base to hydrolyze the remaining acetate groups, followed by established methods such as USP research papers on polyvinyl alcohol (USP39-NF34, pages 5448-5449). It is determined using the method of back titration with hydrochloric acid according to the general principle that has been described. A person skilled in the art knows to select the appropriate sample size, container volume, and reagent volume and concentration for the range of degrees of hydrolysis to be measured.

(10) Measurement of Polyvinyl Alcohol Viscosity Viscosity is measured using a Brookfield LV series viscometer or equivalent measured at 4.00% +/- 0.05% solids.

a. A 4.00% +/- 0.05% solids solution of polyvinyl alcohol is prepared.
Weigh a 500 mL beaker and stirrer. Record the weight. Add 16.00+/-0.01 grams of polyvinyl alcohol sample to the beaker. Add approximately 350-375 mL of deionized water to the beaker and stir the solution. Place the beaker in a warm water bath with a cover plate. Stir at medium speed for 45 minutes to 1 hour or until polyvinyl alcohol is completely dissolved. Turn off the stirrer. Cool the beaker to about 20°C.

Calculate the final weight of the beaker as follows.
Final weight = (weight of empty beaker and stirrer) + (% solids as decimal point x 400)
Example: Empty beaker and stirrer weight = 125.0 grams Polyvinyl alcohol % solids (of the sample) = 97.50% or 0.9750 to the decimal point
Final weight = 125.0 + (0.9750 x 400) = 515.0 grams

A top-mounted balance is zeroed and a beaker with a propeller of polyvinyl alcohol solution is placed on the balance. Add deionized water to bring the weight to a calculated final weight of 515.0 grams.

The solids content of the sample should be 4.00+0.05% to measure the viscosity.

b. Viscosity Measurement A sample of 4% polyvinyl alcohol solution is dispensed into the chamber of the viscometer and attached to the viscometer by inserting a spindle. Sample adapter (SSA) with chamber SC4-13RPY, Ultralow adapter. Spindles are SC4-18 and 00. Equilibration of the sample is achieved at a temperature of 20°C. Start the viscometer and record the steady state viscosity value.

Viscosities <13 cP are reported in 0.01 cP increments, 13-100 cP are reported in 0.1 cP increments, and viscosities greater than 100 cP are reported in 1 cP increments.

If the calculated solution solids content is 4.00±0.05%, no correction to the measured viscosity is required. Otherwise, correct the measured viscosity for the deviation of the solution solids using the following equation.

補正粘度＝２．７１８２８２（Ｌｏｇ補正粘度）

Corrected viscosity = 2.718282 (Log corrected viscosity)
