Description

FIELD OF INVENTION

The present application relates to particles and compositions, such as consumer products, comprising such particles as well as processes for making and using such particles and compositions comprising such particles.

BACKGROUND OF THE INVENTION

Benefit agents, such as perfumes, silicones, waxes, flavors, vitamins and fabric softening agents, are expensive and/or generally less effective when employed at high levels in consumer products, for example, personal care compositions, cleaning compositions, and fabric care compositions. As a result, there is a desire to maximize the effectiveness of such benefit agents. One method of achieving such objective is to improve the delivery efficiencies of such benefit agents. Unfortunately, it is difficult to improve the delivery efficiencies of benefit agents as such agents may be lost due to the agents' physical or chemical characteristics, or such agents may be incompatible with other compositional components or the situs that is treated. One method of improving the delivery efficiency of a benefit agent is to encapsulate such benefit agent. While such efforts may improve the delivery efficiency of the benefit agent, further delivery efficiency improvements are desired as encapsulated benefit agents may be lost before or after they are applied to the situs of interest due to factors such as mechanical or chemical interactions, for example the action of wash and or rinse liquors, and/or charge interactions. In certain applications, the deposition of encapsulated benefit agents is improved by coating the encapsulated benefit agent with a deposition aid that is typically a polymer. Unfortunately, the cationic charged species that are employed to increase deposition of such encapsulates onto clothes lead to an increased aggregation level of encapsulates which can lead to visible clumps in a consumer product and/or inhomogeneous deposition of perfume onto treated surfaces. Thus, what is needed is a encapsulate with a high capsule integrity and a minimized tendency to aggregate.
While not being bound by theory, Applicants believe that the aggregation problem is due to uncoated encapsulate attraction due to Van der Waals forces and bridging flocculation when the encapsulates are coated with a deposition aid. Thus, applicants recognized that the primary source of the aggregation problem was in the slurry making process. Once such problem was solved, the remaining aggregation influences could be managed.
In the present application, Applicants disclose encapsulated benefit agents and specific classes of amine containing polymers that, when combined, provide a high and even deposition profile across multiple different surfaces, for example, hair, skin, and multiple fabrics such as cotton, high surface cottons, polycotton and polyester.
WO201120652 relates to fabric conditioner compositions comprising core-shell particles to deliver enhanced perfume intensity to fabric. WO2010079467 and WO2010084480 relate to encapsulated benefit agents. WO2007062833 relates to a method for forming an encapsulate which comprises the step of forming a outer shell on a pre-existing core-shell benefit-agent encapsulate, wherein the outer shell is formed in the presence of a cellulose-substantive polymer. WO2013107586 relates to personal care composition, preferably for use on human skin and/or hair, including a core-shell benefit agent carrier particle. WO2007148274 relates to detergent compositions comprising selected deposition polymers for improved deposition of fabric care benefit agents.

SUMMARY OF THE INVENTION

The present application relates to a process of makingcompositions, such as consumer products, comprising perfume microcapsules.

TEST METHODS

(1) Extraction of benefit agent delivery particles from finished products.

Except where otherwise specified herein, the preferred method to isolate benefit agent delivery particles from finished products is based on the fact that the density of most such particles is different from that of water. The finished product is mixed with water in order to dilute and/or release the particles. The diluted product suspension is centrifuged to speed up the separation of the particles. Such particles 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 particles. The particles are observed using an optical microscope equipped with crossed-polarized filters or differential interference contrast (DIC), at total magnifications of 100 x and 400 x. The microscopic observations provide an initial indication of the presence, size, quality and aggregation of the delivery particles.
For extraction of delivery particles 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 (eg 20 ml fabric enhancer + 20 ml DI water), mix each aliquot well and centrifuge each aliquot for 30 minutes at approximately 10000 x 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 DIwater 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 x 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 x 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 x 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 particles 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 50ml 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 x 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 x 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 particle enriched and isolated top and bottom layers back together.
If the fabric enhancer has a white color or is difficult to distinguish the particle enriched layers add 4 drops of dye (such as Liquitint Blue JH 5% premix from Miliken & Company, Spartanburg, South Carolina, USA) into the centrifuge tube of step 1 and proceed with the isolation as described.
For extraction of delivery particles from solid finished products which disperse readily in water, mix 1L of DI water with 20 g of the finished product (eg., 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 particles 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 particles from the matrix. The use of organic solvents or drying out of the particles should be avoided during the extraction steps as these actions may damage the delivery particles during this phase.
For extraction of delivery particles from liquid finished products which are not fabric softeners or fabric enhancers (eg., 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 (eg., 100-200 g NaCl) can be added to the diluted suspension in order to increase the density of the solution and facilitate the particles floating to the top layer. If the product has a white color which makes it difficult to distinguish the layers of particles 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 x g, for periods of 5 to 30 minutes. At least six rounds of centrifugation are typically needed to extract and clean sufficient particles for testing. For example, the initial round of centrifugation may be conducted in 50ml tubes spun at 10,000 x 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 x g for 5 mins per round.
If delivery particles are observed microscopically in both the top and bottom layers, then the particles from these two layers are recombined after the final centrifugation step, to create a single sample containing all the delivery particles extracted from that product. The extracted particles 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 delivery particles 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 particles' addition to and extraction from finished product.

(2) Particle Size (Diameter):

A drop of the particle suspension or finished product is placed onto a glass microscope slide and dried under ambient conditions for several minutes to remove the water and achieve a sparse, single layer of solitary particles on the dry slide. Adjust the concentration of particles in the suspension as needed to achieve a suitable particle density on the slide. The slide is placed on a sample stage of an optical microscope equipped and examined at a total magnification of 100 x or 400 x. Images are captured and calibrated for the accurate measurement of particle diameters. Three replicate slides are prepared and analyzed.
For particle size measurement, at least 50 benefit agent delivery particles on each slide are selected for measurement, in a manner which is unbiased by their size and so creates a representative sample of the distribution of particle sizes present. This may be achieved by examining fields-of-view which are selected at random or according to a pre-defined grid pattern, and by measuring the diameter of all the delivery particles present in each field-of-view examined. Delivery particles which appear obviously non-spherical, deflated, leaking, or damaged are unsuitable for measurement, are excluded from the selection process and their diameters are not recorded. The diameter of each suitable delivery particle examined is measured using the microscope and the value is recorded. The recorded particle diameter measurements are used to calculate the percentage of the particles having a particle size within the claimed size range(s), and also to calculate the mean particle size.

(3) Benefit Agent Leakage

The amount of benefit agent leakage from the delivery particles is determined according to the following method:

a.) Obtain two 1 g samples of the raw material slurry of benefit delivery particles.
b.) Add 1 g of the raw material slurry of benefit delivery particles to 99 g of the product matrix in which the particles will be employed, and label the mixture as Sample 1. Immediately use the second 1 g sample of raw material particle slurry in Step d below, in its neat form without contacting product matrix, and label it as Sample 2.
c.) Age the particle-containing product matrix (Sample 1) for 2 weeks at 35°C in a sealed, glass jar.
d.) Using filtration, recover the particles from both samples. The particles in Sample 1 (in product matrix) are recovered after the aging step. The particles in Sample 2 (neat raw material slurry) are recovered at the same time that the aging step began for sample 1.
e.) Treat the recovered particles with a solvent to extract the benefit agent materials from the particles.
f.) Analyze the solvent containing the extracted benefit agent from each sample, via chromatography. Integrate the resultant benefit agent peak areas under the curve, and sum these areas to determine the total quantity of benefit agent extracted from each sample.
g.) Determine the percentage of benefit agent leakage by calculating the difference in the values obtained for the total quantity of benefit agent extracted from Sample 2 minus Sample 1, expressed as a percentage of the total quantity of benefit agent extracted from Sample 2, as represented in the equation below:

(4) Viscosity

Viscosity of liquid finished product is measured using an AR 550 rheometer / viscometer from TA instruments (New Castle, DE, 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.

(5) Aggregation Index

The aggregation index in finished product is determined using the following method:

a. Clean a 212 micron standard laboratory sieve (W.S. Tyler Company, Mentor, Ohio, USA 44060) with water to remove any residues & dry manually &/or allow to air dry.
b. Place ∼20g of product via syringe on the sieve, spread in line over the sieve. Record weight in grams.
c. Tap sieve lightly to allow product to flow through sieve. Light air or nitrogen may be blown over sample to help alleviate air bubbles trapped on the sieve.
d. Count the number of particles remaining on sieve after finished product has passed through the sieve. Record the number of particles. Repeat counting 3 times. Take care to ensure that aggregates are counted and distinguished from air bubbles. Additional air/nitrogen can be used if needed.
e. Repeat steps 1 - 4 up to 4 more times but no less than 3 times.
f. Divide average number of counts by weight used to get aggregation index per gram of sample.
g. Average the three readings of aggregation index per gram of sample for an overall determination.

For the examples above, in a suitable container, combine the ingredients of Phase A. In a separate suitable container, combine the ingredients of Phase B. Heat each phase to 73°C-78°C while mixing each phase using a suitable mixer (e.g., Anchor blade, propeller blade, or IKA T25) until each reaches a substantially constant desired temperature and is homogenous. Slowly add Phase B to Phase A while continuing to mix Phase A. Continue mixing until batch is uniform. Pour product into suitable containers at 73-78°C and store at room temperature. Alternatively, continuing to stir the mixture as temperature decreases results in lower observed hardness values at 21 and 33 °C.
