Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to fabric treatment compositions comprising an aminosilioxane polymer nanoemulsion and methods of making said nanoemulsions and fabric treatment compositions. More specifically, the present invention relates to a process for making aminosiloxane polymer nanoemulsions that may be used to protect surfaces from being soiled or wetted. 
       BACKGROUND OF THE INVENTION 
       [0002]    Numerous attempts have been made to develop a treatment composition that provides protection of surfaces by repelling water and oil based soils from the surface. Fluoropolymers, such as those used in Scotchguard® from 3M, have become well established as soil-repellant molecules. However, fluoropolymers are not preferred due to environmental, health and safety concerns, such as the potential and possibility of persistent bioaccumulation and toxicity. 
         [0003]    Amino-modified silicone microemulsions that contain an amino-modified silicone and a high concentration of both ethylene glycol monoalkyl ether and nonionic surfactant, e.g., polyoxyalkylene branched decyl ether, are known and generally described as transparent in appearance and having a small particle diameter. However, these compositions have the challenge of delivering maximum hydrophobicity to a surface since they incorporate significant amounts of nonionic surfactant to obtain desired stability and particle sizes. 
         [0004]    Unfortunately, to date, the attempts at non-fluorpolymer protection of surfaces continue to demonstrate disadvantages, including low efficiency, difficulty in achieving the desired benefits at affordable cost and in a preferred format, processing and formulation challenges, and product instability. A continued need exists for a non-fluoropolymer technology that delivers depositable benefits to surfaces, such as water and oily soil repellency, in a convenient and stable form and at a high efficiency. 
         [0005]    Even attempts at using non-fluoropolymer technologies have been less than successful due to a general failure to recognize the importance of the order of addition of materials during the making process as well as the processing conditions themselves, in addition to optimization of the solvent system, addition of adjunct ingredients that can enhance performance, and equally the removal of adjuncts that can hinder performance. Applicants have found that by optimizing the order of addition of the raw materials during emulsion making and finished product formulation using said emulsion, the overall stability of the emulsion and finished product can be greatly enhanced. Furthermore, the deposition efficiency and overall soil repellency benefit can be maximized, whilst minimizing the potential for negative results often seen with silicone-containing compositions, such as staining or spotting of fabrics, laundry machine residues, and product discoloration. 
       SUMMARY OF THE INVENTION 
       [0006]    The present invention provides a fabric treatment composition comprising a nanoemulsion made by a process comprising the steps of:
       a) solubilizing a silicone resin in an organic solvent system to yield a silicone resin solution concentration of about 80% or less, wherein the organic solvent system comprises diethyleneglycol monobutyl ether and at least one additional solvent selected from the list consisting of monoalcohols, polyalcohols, ethers of monoalcohols, ethers of polyalcohols, fatty esters, Guerbet alcohols, isoparaffins, naphthols, glycol ethers or mixtures thereof, provided that if the additional solvent is a glycol ether it is not diethyleneglycol monobutyl ether;   b) mixing the silicone resin solution from a) with an aminosiloxane polymer to obtain an aminosiloxane polymer:silicone resin mixture having ratio of about 20:1;   c) allowing the aminosiloxane polymer:silicone resin mixture to age for at least about 6 hours at ambient temperature;   d) adding the aminosiloxane polymer:silicone resin mixture to a vessel;   e) optionally adding with agitation an additional organic solvent to the aminosiloxane polymer:silicone resin mixture;   f) mixing until homogenous;   g) adding a protonating agent;   h) additionally adding an aqueous carrier in an amount to produce the desired concentration of emulsion.       
 
         [0015]    The present invention attempts to solve one more of the needs by providing, in one aspect of the invention, a method of making an aminosiloxane polymer nanoemulsion which can be incorporated into a surface treatment composition, comprising the nanoemulsion. Said nanoemulsion comprising a silicone resin, an aminosiloxane polymer having an amine equivalent of less than about 0.6 meq/g, wherein said polymer has greater than about 5% but less than about 25% of terminal groups comprising hydroxyl functionality; at least one an organic solvent selected from the group consisting of linear alcohols, branched alcohols, Guerbet alcohols, fatty esters, glycol ethers, isoparaffins, naphthols, and mixtures thereof; optionally a second organic solvent; an aqueous carrier; a protonating agent; optionally, a deposition aid polymer selected from cationic and amphoteric polymers, and adjunct ingredients; wherein said nanoemulsion is substantially free of surfactant. 
         [0016]    Another aspect of the invention includes treatment compositions comprising the amino silicone nanoemulsions as described herein. Other aspects of the invention include methods of making treatment compositions comprising the amino silicone nanoemulsions and methods of treating surfaces with treatment compositions comprising the amino silicone nanoemulsions. 
     
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0017]    Features and benefits of the various embodiments of the present invention will become apparent from the following description, which includes examples of specific embodiments intended to give a broad representation of the invention. Various modifications will be apparent to those skilled in the art from this description and from practice of the invention. The scope is not intended to be limited to the particular forms disclosed and the invention covers all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the claims. 
         [0018]    As used herein, the articles including “the,” “a” and “an” when used in a claim or in the specification, are understood to mean one or more of what is claimed or described. 
         [0019]    As used herein, the terms “include,” “includes” and “including” are meant to be non-limiting. 
         [0020]    As used herein, the terms “substantially free of” or “substantially free from” means that the indicated material is at the very minimum not deliberately added to the composition to form part of it, or, preferably, is not present at analytically detectable levels. It is meant to include compositions whereby the indicated material is present only as an impurity in one of the other materials deliberately included. 
         [0021]    Preferably, substantially free from surfactant means that the emulsion comprises at most 1 percent by weight of surfactant, more preferably at most 0.1 percent by weight of surfactant. 
         [0022]    As used herein, the term nanoemulsion refers to thermodynamically stable oil in water emulsions that have extremely small droplet sizes (below 750 nm, or typically below 250 nm). These materials have special properties, including optical translucency, very large dispersed phase surface-to-volume ratios and long term kinetic stability. Due to similarity in appearance, translucent nanoemulsions are sometimes confused with microemulsions, which belong to another class of stable (thermodynamically) and optically clear colloidal systems. Microemulsions are spontaneously formed by “solubilizing” oil molecules with a mixture of surfactants, co-surfactants and co-solvents. The required surfactant concentration in a microemulsion is typically several times higher than that in a nanoemulsion and significantly exceeds the concentration of the dispersed phase (generally, oil). Because of many undesirable side-effects caused by surfactants, this is disadvantageous or prohibitive for many applications. In addition, the stability of microemulsions is easily compromised by dilution, heating, or changing pH levels. By contrast nanoemulsions in accordance with the present invention are formed by judiciously selecting solvent systems that provide adequate dissolution of the siloxanes and also exhibit some level of miscibility with water, thus a stable aqueous emulsion can be achieved without the use of surfactants. Without wishing to be bound by theory, applicants believe that choosing a solvent or solvent system whereby the solvents exhibit dual polarity, these solvents of choice can behave similarly to surfactants in solution without introducing the wetting effect that surfactants typically bring. Thus, it is possible to deliver an oil-in-water emulsion, without having surfactant present, that is capable of providing maximum hydrophobicity to a target surface. 
         [0023]    All cited patents and other documents are, in relevant part, incorporated by reference as if fully restated herein. The citation of any patent or other document is not an admission that the cited patent or other document is prior art with respect to the present invention. 
         [0024]    In this description, all concentrations and ratios are on a weight basis of the total nanoemulsion composition, all pressures are equal to 0.10 MPa (absolute) and all temperatures are equal to 20° C. unless otherwise specified. 
         [0025]    Known amino silicone microemulsions and methods for preparing amino silicone microemulsions employ high levels of solvent and nonionic surfactant (e.g., 12% ethylene glycol monohexyl ether per 100% of amino silicone and 40% polyoxyalkylene branched decyl ether per 100% of amino silicone), and/or require high energy in the form of heat or high shearing forces in order to obtain the desired nanoparticle size. Without being bound by theory, it is believed that the presence of high levels of solvent and surfactant in the emulsion hinders the deposition of the amino silicone on the surface that is to be treated; amino silicone droplets in high-solvent and high-surfactant emulsions tend to stay in the emulsion, rather than deposit on the surface. This results in a poor delivery of any benefit, such as increased water repellency or oil repellency, to the surface. Such benefits may be measured as an increased time to wick on treated fabrics, a reduced dry-time for treated fabrics and/or an increased contact angle on a hard surface. 
         [0026]    In contrast to conventional amino silicone microemulsions, the amino silicone nanoemulsions of the present invention comprise reduced levels of solvent and no intentionally added surfactant and may be obtained without the input of high energy to process the emulsion. Yet, the amino silicone nanoemulsions disclosed herein provide highly efficient deposition on a target surface. Benefits derived from this deposition may generally apply in the area of repellency of water and/or water-based compositions and/or oil and/or oil-based compositions, such as water-based stains and oily soils. Without being bound by theory, it is believed that the amino silicone nanoemulsions disclosed herein comprise self-assembled, spherical, positively charged amino silicone nano-particles (which contain reduced levels of solvent and surfactant). These self-assembled, spherical, positively charged nano-particles exhibit efficient deposition and controlled spreading, that is believed to form a structured film on a surface that provides the repellency benefit as determined by the below specified time to wick method. 
         [0027]    The average particle sizes of the disclosed nanoemulsions range from about 20 nm to about 750 nm, or about 20 nm to about 500 nm, or about 50 nm to about 350 nm, or about 80 nm to about 200 nm, or about 90 nm to about 150 nm. (as measured by Malvern Zetasizer Nano Series instrument). The disclosed nanoemulsions are generally transparent or slightly milky in appearance.

In some aspects, the treatment composition comprises from about 0.001% to about 99% by weight of the composition, of the amino silicone nanoemulsion. In certain aspects, the treatment composition comprises from about 0.001% to about 40%, or from about 0.1% to about 35%, or from about 1% to about 30%, or from about 5% to about 25%, or from about 9% to about 22% or from about 13% to about 18% of the amino silicone nanoemulsion, by weight of the composition. 
         [0088]    In one aspect, the fabric treatment composition comprising a nanoemulsion of the present invention may be made according to a process comprising the steps of:
       a) solubilizing a silicone resin in an organic solvent system to yield a silicone resin solution concentration of about 80% or less, wherein the organic solvent system comprises a single solvent selected from the group consisting of monoalcohols, polyalcohols, ethers of monoalcohols, ethers of polyalcohols, fatty esters, Guerbet alcohols, isoparaffins, naphthols, glycol ethers, provided that if the solvent is a glycol ether it is not diethyleneglycol monobutyl ether;   b) mixing the silicone resin solution from a) with an aminosiloxane polymer to obtain an aminosiloxane polymer:silicone resin mixture having ratio of about 20:1;   c) allowing the aminosiloxane polymer:silicone resin mixture to age for at least about 6 hours at ambient temperature;   d) adding the aminosiloxane polymer:silicone resin mixture to a vessel;   e) optionally adding with agitation an additional organic solvent to the aminosiloxane polymer:silicone resin mixture;   f) mixing until homogenous;   g) adding a protonating agent;   h) additionally adding an aqueous carrier in an amount to produce the desired concentration of nanoemulsion   i) adding the nanoemulsion to a vessel;   j) optionally, adding to the vessel containing the aforementioned nanoemulsion a perfume oil;   k) adding an organic solvent;   l) optionally, adding a deposition aid polymer;   m) adding additional water to achieve the desired finished product concentration;   n) optionally, adding a preservative;   o) optionally, adding a dispersant;   p) adding a protonating agent; and   q) optionally, adding a dye.       
 
         [0106]    Examples of treatment compositions include, but are not limited to, laundry spray treatment products, laundry pre-treatment products, fabric enhancer products, hard surface treatment compositions (hard surfaces include exterior surfaces, such as vinyl siding, windows, and decks), carpet treatment compositions, and household treatment compositions. Examples of fabric care compositions suitable for the present disclosure include, but are not limited to, laundry spray treatment products, laundry pre-treatment products, laundry soak products, and rinse additives. Examples of suitable home care compositions include, but are not limited to, rug or carpet treatment compositions, hard surface treatment compositions, floor treatment compositions, and window treatment compositions. 
         [0107]    In some aspects, the treatment composition may be provided in combination with a nonwoven substrate, as a treatment implement. 
         [0108]    In certain aspects, the compositions provide water and/or oil repellency to the treated surfaces, thereby reducing the propensity of the treated surface to become stained by deposited water- or oil-based soils. 
         [0109]    By “surfaces” it is meant any surface. These surfaces may include porous or non-porous, absorptive or non-absorptive substrates. Surfaces may include, but are not limited to, celluloses, paper, natural and/or synthetic textiles fibers and fabrics, imitation leather and leather. Selected aspects of the present invention are applied to natural and/or synthetic textile fibers and fabrics. 
         [0110]    By “treating a surface” it is meant the application of the composition onto the surface. The application may be performed directly, such as spraying or wiping the composition onto a hard surface. The composition may or may not be rinsed off, depending on the desired benefit. 
         [0111]    The present invention also encompasses the treatment of a fabric as the surface. This can be done either in a “pretreatment mode”, where the composition is applied neat onto the fabric before the fabrics are washed or rinsed, or a “post-treatment mode”, where the composition is applied neat onto the fabric after the fabric is washed or rinsed. The treatment may be performed in a “soaking mode”, where the fabric is immersed and soaked in a bath of neat or diluted composition. The treatment may also be performed in a “through the wash” or “through the rinse” mode where the treatment composition, as defined herein, is added to the wash cycle or the rinse cycle of a typical laundry wash machine cycle. When used in the wash or rinse cycle, the compositions are typically used in a diluted form. By “diluted form” it is meant that the compositions may be diluted in the use, preferably with water at a ratio of water to composition up to 2000:1, or from 1:1 to about 1000:1, or from 3:1 to about 500:1, or from 5:1 to 200:1, or from 10:1 to 80:1. 
         [0112]    Such treatment compositions may comprise carriers, which may be any known material that is useful in delivering the treatment compositions to the surface to be treated. The carrier may be as simple as a single component delivery vehicle, such as water or alcohol, which would allow the nanoemulsion to be sprayed onto a surface. Alternatively, the carrier may be complex, such as a cleaning composition, e.g., a laundry detergent where the nanoemulsion would be applied in conjunction with the other beneficial uses of the complex carrier. 
         [0113]    Such treatment compositions may comprise various other materials, including bleaching agents, bleach activators, builders, chelating agents, smectite clays, dye transfer inhibiting agents, dispersants, enzymes, and enzyme stabilizers, catalytic metal complexes, polymeric dispersing agents, clay and soil removal/anti-redeposition agents, brighteners, suds suppressors, suds boosters, dyes, additional perfumes and perfume delivery systems, structure elasticizing agents, fabric softeners, carriers, hydrotropes, processing aids and/or pigments.

When anionic monomeric units are present in the polymer, it is understood that the polymer is net cationic i.e., the number of cationic monomeric units are more than the number of anionic monomeric units in the polymer chain. Specifically, the cationic polymers are compatible with detersive enzymes in the detergent composition and are capable of assisting and/or enhancing the deposition of benefit agents onto fabrics during laundering.

         [0117]    The polymer may optionally comprises anionic monomers, such as acrylic acid, methacrylic acid, maleic acid, vinyl sulfonic acid, styrene sulfonic acid, acrylamidopropylmethane sulfonic acid (AMPS) and their salts. 
         [0118]    The polymer may optionally be cross-linked. Crosslinking monomers include, but are not limited to, ethylene glycoldiacrylatate, divinylbenzene, butadiene. 
         [0119]    The most preferred polymers are poly(acrylamide-co-diallyldimethylammonium chloride), poly(acrylamide-methacrylamidopropyltrimethyl ammonium chloride), poly(acrylamide-co-N,N-dimethyl aminoethyl methacrylate), poly(acrylamide-co-N,N-dimethyl aminoethyl methacrylate), poly(hydroxyethylacrylate-co-dimethyl aminoethyl methacrylate), poly(hydroxpropylacrylate-co-dimethyl aminoethyl methacrylate), poly(hydroxpropylacrylate-co-methacrylamidopropyltrimethylammonium chloride). 
         [0120]    In order for the deposition polymers to be formulable and stable in the composition, it is important that the monomers are incorporated in the polymer to form a copolymer, especially true when monomers have widely different reactivity ratios are used. In contrast to the commercial copolymers, the deposition polymers herein have a free monomer content less than 10%, preferably less than 5%, by weight of the monomers. Preferred synthesis conditions to produce reaction products containing the deposition polymers and low free monomer content are described below. 
         [0121]    The deposition assisting polymers can be random, block or grafted. They can be linear or branched. The deposition assisting polymers comprises from about 1 to about 60 mol percent, preferably from about 1 to about 40 mol percent, of the cationic monomer repeat units and from about 98 to about 40 mol percent, from about 60 to about 95 mol percent, of the nonionic (i.e., “neutral”) monomer repeat units. 
         [0122]    The deposition assisting polymer has a charge density of about 0.1 to about 5.0 milliequivalents/g (meq/g) of dry polymer, preferably about 0.2 to about 3 meq/g. This refers to the charge density of the polymer itself and is often different from the monomer feedstock. For example, for the copolymer of acrylamide and diallyldimethylammonium chloride with a monomer feed ratio of 70:30, the charge density of the feed monomers is about 3.05 meq/g. However, if only 50% of diallyldimethylammonium is polymerized, the polymer charge density is only about 1.6 meq/g. The polymer charge density is measured by dialyzing the polymer with a dialysisis membrane or by NMR. For polymers with amine monomers, the charge density depends on the pH of the carrier. For these polymers, charge density is measured at a pH of 7. The weight-average molecular weight of the polymer will generally be between 10,000 and 5,000,000, preferably from 100,000 to 2,00,000 and even more preferably from 200,000 and 1,500,000, as determined by size exclusion chromatography relative to polyethyleneoxide standards with RI detection. The mobile phase used is a solution of 20% methanol in 0.4M MEA, 0.1 M NaNO 3 , 3% acetic acid on a Waters Linear Ultrandyrogel column, 2 in series. Columns and detectors are kept at 40° C. Flow is set to 0.5 mL/min.

       Methods of Using Treatment Compositions 
       [0141]    The treatment compositions of the present disclosure may be used in a method of treating a surface. The method of treating a surface comprises the step of applying the amino silicone nanoemulsion treatment composition of the present disclosure to a surface, where the surface is selected from fabric or a hard surface. 
       Fabric Treatment 
       [0142]    The treatment compositions disclosed in the present specification may be used to treat a fabric, such as those described herein. Typically at least a portion of the fabric is contacted with an embodiment of the aforementioned fabric care compositions, in neat form or diluted in a liquor, for example, a wash liquor and then the fabric may be optionally washed and/or rinsed and/or dried without further treatment. In one aspect, a fabric is optionally washed and/or rinsed, contacted with an embodiment of the aforementioned fabric care compositions and then optionally washed and/or rinsed. For purposes of the present disclosure, washing includes but is not limited to, scrubbing, and mechanical agitation. The fabric may comprise most any fabric capable of being laundered or treated. 
         [0143]    The fabric care compositions disclosed in the present specification can be used to form aqueous washing or treatment solutions for use in the laundering and/or treatment of fabrics. Generally, an effective amount of such compositions is added to water, preferably in a conventional fabric laundering automatic washing machine, to form such aqueous laundering solutions.

         [0145]    Without being bound by theory it is believed the treatment of a fabric with compositions disclosed in the present specification may increase the time-to-wick of the fabric. Table VII shows an increase in the time-to-wick of cotton fabric as a result of treatment with examples of compositions disclosed in the present specification.

The aqueous washing and/or treatment solution so formed is then contacted with the hard surface to be washed or treated therewith. 
         [0149]    Without being bound by theory, it is believed the treatment of the hard surface with compositions disclosed in the present specification may increase the contact angle of water or water-based composition and/or oily substances on the hard surface. Without being bound by theory it is believed that increasing the contact angle of substances on a hard surface increases the ease of removing said substances from the surface 
         [0150]    In some aspects, there is provided a method of treating a surface comprising the step of applying the amino silicone nanoemulsion treatment composition of the present disclosure to a surface, where the surface is a hard surface and where the contact angle relative to the untreated hard surface is increased. 
         [0151]    While various specific embodiments have been described in detail herein, the present disclosure is intended to cover various different combinations of the disclosed embodiments and is not limited to those specific embodiments described herein. The various embodiments of the present disclosure may be better understood, when read in conjunction with the following representative examples. The following representative examples are included for purposes of illustration and not limitation. 
       Test Methods 
       [0152]    Time to Wick (T2W) Measurement Method 
         [0153]    The fabric Time to Wick property is a measure of the water repellency of a fabric, where longer times indicate greater repellency. Water repellency is measured when a drop of water is applied to the fabric, such as white 6.1 oz (165-200 gsm) Gildan Ultra 100% Cotton t-shirts (size large, item number 2000, Gildan USA, Charleston, S.C.). The Gildan t-shirts are prepared by de-sizing for 2 cycles of laundering with clean rinses using the AATCC 2003 standard reference liquid detergent without optical brighteners (AATCC—American Association of Textile Chemists and Colorists, Research Triangle Park, N.C., USA) in a standard top-loader, North American style washing machine, such as a Kenmore 600 Model 110.28622701. For treatment, 12 t-shirts are added to the drum of a standard washing machine, set on Heavy Duty wash cycle, water level equal to 17 gallons (Super load size), warm water, selected with single rinse option. Water is regulated to standardize the wash temperature to 90° F., Rinse to 60° F., and water hardness to 6 grain per gallon. Detergent is added to the wash water, such as Tide liquid Detergent (50.0 g dose), Clean Breeze scent. With the fabrics in the washer, the rinse water is allowed to fill the tub. Prior to agitation, the fabric treatment composition of the present invention (40 grams) is equally dispersed and added to the rinse water, followed by completion of the rinse cycle. The garments are then placed in a standard dryer, such as a Kenmore standard 80 series, cotton cycle (high heat), for 30 minutes or until dry. The fabrics are then removed from the dryer and placed in a cool, well ventilated room with controlled humidity set at 50% RH, and temperature regulated to 70° F., for a period of 24-48 hours. The section of the fabric that will be measured for Time to Wick is subjected to UV light, such as standard overhead lab lighting, for 24-48 hours prior to measurement. Treated test fabric is compared for Time to Wick value versus an untreated control fabric that has been prepared in a similar manner as the test fabric without the addition of the fabric treatment composition. 
         [0154]    The Time to Wick value is measured as follows: On a flat, level hard surface (e.g. benchtop) a fresh square of a paper towel at least 10 cm×10 cm in size, is placed inside the prepared t-shirt so that 1 layer of fabric is being measured. A 300 μL drop of DI water is then dispensed onto the fabric surface from a calibrated pipette. The process of absorption of the liquid drop is visually monitored and recorded counting the time elapsed in seconds. Eight drops are administered per t-shirt, with each drop placed at a different location separate from all adjacent drops. 
         [0155]    For each drop, the time differential between when the drop is applied and when absorbed is calculated and recorded in seconds. The time at drop absorption is defined as being the earliest time point at which no portion of the drop is observed remaining above the surface of the fabric. If the drop remains after 10 minutes, observation is discontinued. Such drops are recorded as having a time differential of 600 seconds. The Time to Wick value for a given liquid on fabric is the average of the time differentials recorded for 8 drops of that liquid. In order to determine the effect of a treatment, comparisons are made between the average Time to Wick value obtained from the treated fabric, versus the average obtained from its untreated control fabric using the same liquid, where longer times indicate greater repellency. 
       Particle Size Measurement Test Method by Using Malvern Zetasizer Nano ZS 
       [0156]    The organosilicone nanoemulsions finished product containing the nanoemulsions are measured either neat or diluted with DI water to a specific concentration (1:10, 1:500 or 1:1000) with filtered DI water (using Gelman acrodisc LC PVDF 0.45 μm) prior to making particle size measurements. The particle size measurement is performed immediately after the sample completely disperses in water. The data is reported as the average of 3 readings. 
       Sample Preparation: 
       [0157]    The dilution used will be dependent upon the type of sample: silicone emulsions are diluted at a concentration of 1:500 and 1:1000 and finish products are measured as neat and diluted to a concentration of 1:10 in DI water.
       Before diluting the sample, gently invert it several times to mix it well.   Rinse the 10 ml vial with filtered DI water to remove any dust then pipette a specific amount of filtered DI water and sample to the vial to make up the correct concentration (1:10, 1:500 or 1:1000). Invert the vial several times to make sure the sample completely disperses in water.   Add 1 ml of diluted sample or neat sample to a clean cuvette ensuring that there are no air bubbles present in the sample.       
 
       Instrument Set up Conditions: 
       [0161]    The particle size measurements are made via Malvern Zetasizer Nano Series ZS, with model #ZEN3600 with the fixed parameter settings for both Silicone emulsion and finish product:

       Test Method for Determining the Range of Nanoparticle Typical Diameters and the Presence/Absence of Nanoparticle Aggregates, Using a Cryo-Transmission Electron Microscope (Cryo-TEM). 
       [0162]    Samples of the liquid composition to be tested are prepared for microscopic analysis in order to observe nanoparticles that may be suspended in the composition. Sample preparation involves pipetting approximately 5 μl of the liquid composition onto a holey carbon grid (such as Lacey Formvar Carbon on 300 mesh copper grid, P/N 01883-F, available from Ted Pella Inc., Redding, Calif., U.S.A., or similar). The excess liquid is blotted away from the edge of the grid with a filter paper (such as Whatman brand #4, 70 mm diameter, manufactured by GE Healthcare/General Electric Company, Fairfield, Conn., U.S.A., or similar). The grid-mounted sample is plunged rapidly into liquid ethane using a freezing apparatus capable of producing a flash-frozen vitreous thin film of sample lacking crystalline ice (such as a Controlled Environment Vitrification System (CEVS device), or similar apparatus). The apparatus configuration and use of a CEVS device is described in the Journal of Electron Microscopy Technique volume 10 (1988) pages 87-111. Liquid ethane may be prepared by filling an insulated container with liquid nitrogen and placing a second smaller vessel into the liquid nitrogen. Gaseous ethane blown through a syringe needle into the second vessel will condense into liquid ethane. Tweezers pre-cooled in liquid nitrogen are used to rapidly handle the frozen grids while taking great care to maintain the vitreous non-crystalline state of the sample and minimize the formation of frost on the sample. After being flash frozen the grid-mounted samples are stored under liquid nitrogen until being loaded into the cryo-TEM via a cryo transfer holder (such as Gatan model 626 Cryo-Holder available from Gatan Inc., Warrendale, Pa., U.S.A., attached to a TEM instrument such as the model Tecnai G 2  20 available from FEI Company, Hillsboro, Oreg., U.S.A., or similar). The cryo-TEM is equipped with a camera such as the Gatan Model 994 UltraScan 1000XP (available from Gatan Inc., Warrendale, Pa., U.S.A.). The grid-mounted frozen samples are imaged in the cryo-TEM using low beam dosages (such as 200 KV in Low Dose Mode) in order to minimize sample damage. Suitable magnifications are selected in order to observe the size of nanoparticles which may be present. This may include magnifications in the range of 5,000x-25,000x. During imaging the sample is kept as cold as possible, typically at or near the temperature of liquid nitrogen (approximately minus 175° C.). Images of the samples are carefully examined to detect the presence of artifacts. A grid-mounted sample is discarded if any crystalline ice. Images are inspected for beam damage artifacts and are rejected if damage is observed. For each grid-mounted sample, representative images are captured of approximately 40 fields of view which are representative of the sample. These images are used to determine the range of nanoparticle typical diameters, and to determine the presence or absence of nanoparticle aggregates. In each image, the diameters are measured from nanoparticles which are typical of that image. The range of typical diameter values reported for the composition is the range of the diameters measured across all images captured from that composition. In each image, the spacing between nanoparticles is observed. A nanoparticle aggregate is defined as a cluster which contains at least 10 nanoparticles clumped together, rather than being individually dispersed. Nanoparticle aggregates are reported as present if at least one nanoparticle aggregate is observed in at least one image captured from that composition.

       The amine oil U has a viscosity about 1000 mm 2 /s at 25° C. [corresponds to units of formulas 7+8+9+10=230], functional radicals —(CH 2 ) 3 NH(CH 2 )NH 2  [corresponds to R 2 ], amine number of 0.5 mmol/g, 92% SiMe 3  end groups, and 8% SiMe 2 OH end groups [corresponds to units of formulas 9/10=11.5].   The amine oil V has a viscosity about 1000 mm 2 /s at 25° C. [corresponds to units of formulas 7+8+9+10=230], functional radicals —(CH 2 ) 3 NH(CH 2 )NH 2  [corresponds to R 2 ], amine number of 0.5 mmol/g, 85% SiMe 3  end groups, and 15% SiMe 2 OH end groups [corresponds to units of formulas 9/10=5.7].   The amine oil W has a viscosity about 1000 mm 2 /s at 25° C. [corresponds to units of formulas 7+8+9+10=230], functional radicals —(CH 2 ) 3 NH(CH 2 )NH 2  [corresponds to R 2 ], amine number of 0.5 mmol/g, 80% SiMe 3  end groups, and 20% SiMe 2 OH end groups [corresponds to units of formulas 9/10=4.0].   Mix fluids until completely homogenous using an Ika® RWA-20 mixer with a 4-blade agitator having 45° pitch on each blade using appropriate level of agitation. Place lid on container and allow oil mixture to age at room temperature for at least 72 hours.
