## Title
Amino silicone nanoemulsion

## Abstract

The present invention relates to amino silicone nanoemulsions. More specifically, the present invention relates to amino silicone nanoemulsions that may be used to protect surfaces from being soiled or wetted.

## Background
FIELD OF THE INVENTION
The present invention relates to amino silicone nanoemulsions. More specifically, the present invention relates to amino silicone nanoemulsions that may be used to protect surfaces from being soiled or wetted.
BACKGROUND OF THE INVENTION
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, and health and safety concerns, such as potential and possibility of persistent bioaccumulation and toxicity.
The combination of polyorganosiloxane fluids and silicone resins in attempts to treat hard or soft surfaces is also known. Silicone resins are highly cross-linked silicone materials that have very high viscosities. These materials are generally difficult to handle in a manufacturing environment and difficult to formulate with, given their high viscosities. And, incorporating compositions containing silicone resins into liquid-based and emulsion-based treatment formulations generally requires high energy processes.
And, an amino-modified silicone microemulsion that contains an amino-modified silicone and a high concentration of both ethylene glycol monoalkyl ether and nonionic surfactant, e.g., polyoxyalkylene branched decyl ether, is known; this amino-modified silicone nanoemulsion is described as transparent in appearance and having a small particle diameter.
Unfortunately, to date, the attempts at non-fluoropolymer 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 form and at a high efficiency.
SUMMARY OF THE INVENTION
The present invention attempts to solve one more of the needs by providing, in one aspect of the invention, an amino silicone nanoemulsion, which comprises a reduced concentration of solvent and surfactant. The amino silicone nanoemulsion comprises one or more amino silicone compounds; from about 0.1% to about 20% of a solvent, by weight of the amino silicone compound; from about 1% to about 40% of a surfactant, by weight of the amino silicone compound; and a protonating agent, where the sum of the solvent and the surfactant is less than about 50% by weight of said amino silicone compound and where the amino silicone nanoemulsion is substantially free of silicone resin.
The invention also relates to methods of making and using these amino silicone nanoemulsions.
Another aspect of the invention includes treatment compositions that comprise amino silicone nanoemulsions, which comprise reduced concentrations of solvent and surfactant, and the use thereof. 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
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.
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.
As used herein, the terms “include,” “includes” and “including” are meant to be non-limiting.
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.
As used herein, the term nanoemulsion refers to thermal dynamically stable oil in water emulsions that have extremely small droplet sizes (below 350 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 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.
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.
In this description, all concentrations and ratios are on a weight basis of the cleaning composition unless otherwise specified.
The present invention encompasses an amino silicone nanoemulsion. The amino silicone nanoemulsion comprises one or more amino silicone compounds; from about 0.1% to about 20%, by weight of the amino silicone compound, of a solvent; from about 1% to about 30% by weight of the amino silicone compound of a surfactant; and a protonating agent, where the sum of the solvent and the surfactant is less than 50% by weight of said amino silicone compound and where the amino silicone nanoemulsion is substantially free of a silicone resin.
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 fabrics, a reduced dry-time on hair and/or an increased contact angle on a hard surface.
In contrast to conventional amino silicone microemulsions, the amino silicone nanoemulsions of the present invention comprise reduced levels of solvent and surfactant and may be obtained without the input of high energy. Yet, the amino silicone nanoemulsions disclosed herein provide a 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, forming a structured film on a surface that provides the repellency benefit.
The average particle sizes of the disclosed nanoemulsions range from about 20 nm to about 350 nm, or about 20 nm to about 250 nm, or about 20 nm to about 200 nm, or about 30 nm to about 140 nm, or about 50 nm to about 100 nm. (as measured by Malvern Zetasizer Nano Series instrument.). The disclosed nanoemulsions are generally transparent or slightly milky in appearance.

Surfaces may include, but are not limited to, celluloses, paper, natural and/or synthetic textiles fibers and fabrics, imitation leather and leather, hair and skin. Selected aspects of the present invention are applied to natural and/or synthetic textile fibers and fabrics.
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.
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 500:1, or from 5:1 to 200:1, or from 10:1 to 80:1.
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.
Such treatment compositions may comprise various other materials, including bleaching agents, bleach activators, detersive surfactants, 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.
Detersive Surfactants—The treatment compositions according to the present disclosure may comprise a detersive surfactant or detersive surfactant system. Suitable detersive surfactants include nonionic surfactant, anionic surfactant, cationic surfactant, ampholytic surfactant, zwitterionic surfactant, semi-polar nonionic surfactant, or a mixture thereof. The detersive surfactant is typically present at a level of from about 0.1%, from about 1%, or even from about 5%, by weight of the treatment composition, to about 99.9%, to about 80%, to about 35%, or even to about 30%, by weight of the treatment composition. The specific surfactants described above, in the context of the nanoemulsion itself, may be included in the treatment compositions as detersive surfactants. When included in the treatment compositions (as opposed to the nanoemulsion itself), these surfactants are generally included at appropriate concentrations such that the surfactants provide a detersive or cleaning benefit.

When present, the compositions will typically comprise at least about 1% builder, or from about 5% or 10% to about 80%, 50%, or even 30% by weight, of said builder. Builders include, but are not limited to, the alkali metal, ammonium and alkanolammonium salts of polyphosphates, alkali metal silicates, alkaline earth and alkali metal carbonates, aluminosilicate builders polycarboxylate compounds, ether hydroxypolycarboxylates, copolymers of maleic anhydride with ethylene or vinyl methyl ether, 1,3,5-trihydroxybenzene-2,4,6-trisulphonic acid, and carboxymethyl-oxysuccinic acid, the various alkali metal, ammonium and substituted ammonium salts of polyacetic acids such as ethylenediamine tetraacetic acid and nitrilotriacetic acid, as well as polycarboxylates such as mellitic acid, succinic acid, oxydisuccinic acid, polymaleic acid, benzene 1,3,5-tricarboxylic acid, carboxymethyloxysuccinic acid, and soluble salts thereof.
Chelating Agents—The treatment compositions may also optionally contain one or more copper, iron and/or manganese chelating agents. If utilized, chelating agents will generally comprise from about 0.1% by weight of the compositions herein to about 15%, or even from about 3.0% to about 15% by weight of the compositions herein.

When present in the compositions herein, the dye transfer inhibiting agents are present at levels from about 0.0001%, from about 0.01%, from about 0.05% by weight of the cleaning compositions to about 10%, about 2%, or even about 1% by weight of the cleaning compositions.
Dispersants—The treatment compositions of the present disclosure may also contain dispersants. Suitable water-soluble organic materials are the homo- or co-polymeric acids or their salts, in which the polycarboxylic acid may comprise at least two carboxyl radicals separated from each other by not more than two carbon atoms.

A typical combination is a cocktail of conventional applicable enzymes like protease, lipase, cutinase and/or cellulase in conjunction with amylase.
Enzyme Stabilizers—Enzymes for use in the treatment compositions, e.g., detergents, may be stabilized by various techniques. The enzymes employed herein can be stabilized by the presence of water-soluble sources of calcium and/or magnesium ions in the finished compositions that provide such ions to the enzymes.
In some aspects, the treatment composition comprises an amino silicone nanoemulsion and a carrier. Typically, the amino silicone nanoemulsion is substantially free of a silicone resin. In some aspects, the treatment composition comprises an amino silicone nanoemulsion, a carrier, and a perfume, a detersive surfactant system, or a cleaning adjunct additive. The detersive surfactant system may comprise one or more surfactants selected from nonionic surfactants, cationic surfactants, anionic surfactants, zwitterionic surfactants, ampholytic surfactants, or amphoteric surfactants. In some aspects, the detersive surfactant system comprises a surfactant selected from C10-C16 alkyl benzene sulfonates, C8-C18 alkyl sulfate, C8-C18 alkyl ethoxylated sulfate, or a mixture thereof.
In certain aspects of the present disclosure, the treatment composition is a fabric care composition. Such a fabric care composition may take the form of detergent composition or a rinse added fabric conditioning compositions. Such compositions may comprise a fabric softening active and a dispersant polymer, to provide a stain repellency benefit to fabrics treated by the composition, typically from about 0.00001 wt. % (0.1 ppm) to about 1 wt. % (10,000 ppm), or even from about 0.0003 wt. % (3 ppm) to about 0.03 wt. % (300 ppm) based on total rinse added fabric conditioning composition weight. In another specific aspect, the compositions are rinse added fabric conditioning compositions. Examples of typical rinse added conditioning composition can be found in U.S. Provisional Patent Application Ser. No. 60/687,582 filed on Oct. 8, 2004.
In some aspects, the treatment composition is encapsulated in a water-soluble or water-dispersible pouch.

Granular treatment compositions may include any number of conventional detergent ingredients, such as the components described above, e.g., surfactants, chelants, enzymes. Granular detergent compositions typically comprise from about 1% to 95% by weight of a surfactant. Granular detergents can be made by a wide variety of processes, non-limiting examples of which include spray drying, agglomeration, fluid bed granulation, marumarisation, extrusion, or a combination thereof. Bulk densities of granular detergents generally range from about 300 g/1-1000 g/l. The average particle size distribution of granular detergents generally ranges from about 250 microns-1400 microns.

Method of Making Treatment Composition Comprising Amino Silicone Nanoemulsion
The treatment compositions disclosed herein may be prepared by combining the components thereof in any convenient order and by mixing, e.g., agitating, the resulting component combination to form a phase stable cleaning composition. In one aspect, a liquid matrix is formed containing at least a major proportion, or even substantially all, of the liquid components, e.g., nonionic surfactant, the non-surface active liquid carriers and other optional liquid components, with the liquid components being thoroughly admixed by imparting shear agitation to this liquid combination. For example, rapid stirring with a mechanical stirrer may usefully be employed. While shear agitation is maintained, substantially all of any anionic surfactant and the solid ingredients can be added. Agitation of the mixture is continued, and if necessary, can be increased at this point to form a solution or a uniform dispersion of insoluble solid phase particulates within the liquid phase. After some or all of the solid-form materials have been added to this agitated mixture, particles of any enzyme material to be included, e.g., enzyme prills are incorporated. As a variation of the composition preparation procedure described above, one or more of the solid components may be added to the agitated mixture as a solution or slurry of particles premixed with a minor portion of one or more of the liquid components. After addition of all of the composition components, agitation of the mixture is continued for a period of time sufficient to form compositions having the requisite viscosity and phase stability characteristics. Frequently this will involve agitation for a period of from about 30 to 60 minutes.
In another aspect of producing liquid cleaning compositions, the amino silicone nanoemulsion may first be combined with one or more liquid components to form an aqueous amino silicone nanoemulsion premix, and this aqueous amino silicone nanoemulsion premix is added to a composition formulation containing a substantial portion, for example more than 50% by weight, more than 70% by weight, or even more than 90% by weight, of the balance of components of the cleaning composition. For example, in the methodology described above, both the aqueous amino silicone nanoemulsion premix and the enzyme component are added at a final stage of component additions. In another aspect, the aqueous amino silicone nanoemulsion is encapsulated prior to addition to the detergent composition, the encapsulated aqueous amino silicone nanoemulsion is suspended in a structured liquid, and the suspension is added to a composition formulation containing a substantial portion of the balance of components of the cleaning composition.
Methods of Using Treatment Compositions
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, skin, hair, or a hard surface.
Fabric Treatment
The treatment compositions disclosed in the present specification may be used to clean or 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.
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. The aqueous washing solution so formed is then contacted, preferably under agitation, with the fabrics to be laundered therewith. An effective amount of the fabric care composition, such as the liquid detergent compositions disclosed in the present specification, may be added to water to form aqueous laundering solutions that may comprise from about 500 to about 7,000 ppm or even from about 1,000 to about 3,000 ppm of fabric care composition.
In one aspect, the fabric care compositions may be employed as a laundry additive, a pre-treatment composition and/or a post-treatment composition.
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 1 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.
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 fabric and where the water repellency relative to the untreated fabric is increased, as measured by an increase in Time to Wick. In certain aspects, the increase in Time to Wick is greater than about 100 seconds, or greater than about 500 seconds, or greater than about 1200 seconds. In some aspects, the oil repellency relative to the untreated fabric is increased, as measured by an increase in Time to Wick. In some aspects, the oil repellency relative to the untreated fabric is increased, as measured by an increase in Time to Wick greater than about 10 seconds.
Hair Treatment
The treatment compositions disclosed in the present specification may be used to clean or treat hair. Typically at least a portion of the hair is contacted with an embodiment of the aforementioned hair care compositions, in neat form or diluted in a liquor, for example, a wash liquor, and then the hair may be optionally washed and/or rinsed and/or dried without further treatment. In one aspect, hair is optionally washed and/or rinsed, contacted with an embodiment of the aforementioned hair care compositions and then optionally washed and/or rinsed and/or dried without further treatment. For purposes of the present disclosure, washing includes but is not limited to, scrubbing, and mechanical agitation.
The hair care compositions disclosed in the present specification can be used to form aqueous washing or treatment solutions for use in the washing and/or treatment of hair. Generally, an effective amount of such compositions is added to water to form such aqueous washing and/or treatment solutions. The aqueous washing and/or treatment solution so formed is then contacted with the hair to be washed or treated therewith.
Without being bound by theory, it is believed the treatment of the hair with compositions disclosed in the present specification may decrease the dry-time of the hair after treatment. For example if the treatment were a hair-conditioning treatment applied in the shower, the time required for the hair to dry after such treatment would be reduced by virtue of the treatment, relative to the time required for the hair to dry if there had been no such treatment. Table 2 shows a decrease in the dry-time of hair as a result of treatment with examples of compositions disclosed in the present specification.
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 hair or skin and where the dry time relative to the untreated hair or skin is decreased, as measured by an decrease in Technical Dry Time. In some aspects, the Technical Dry Time is less than about 3 seconds.
Hard Surfaces
The treatment compositions disclosed in the present specification may be used to clean or treat hard surfaces, such as those described herein. Typically at least a portion of the hard surface is contacted with an embodiment of the aforementioned hard surface care compositions, in neat form or diluted in a liquor, for example, a wash liquor and then the hard surface may be optionally washed and/or rinsed and/or dried without further treatment. In one aspect, a hard surface is optionally washed and/or rinsed, contacted with an embodiment of the aforementioned hard surface care compositions and then optionally washed and/or rinsed and/or dried without further treatment. For purposes of the present disclosure, washing includes but is not limited to, scrubbing, and mechanical agitation.
The hard surface care compositions disclosed in the present specification can be used to form aqueous washing or treatment solutions for use in the washing and/or treatment of hard surfaces. Generally, an effective amount of such compositions is added to water to form such aqueous washing and/or treatment solutions. The aqueous washing and/or treatment solution so formed is then contacted with the hard surface to be washed or treated therewith.
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. Table 3 shows an increase in the contact angle of a silica wafer as a result of treatment with examples of compositions disclosed in the present specification.
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. In some aspects, the contact angle is greater than about 36 degrees.
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
Time to Wick (T2W) Measurement Method
The fabric Time to Wick property is a measure of the water repellency or oil repellency of a fabric, where longer times indicate greater repellency. Water repellency is measured when a drop of water is applied to the fabric, whereas oil repellency is measured when a drop of oil is applied to the fabric. The Time to Wick value is measured as follows: The tests are conducted in a well-ventilated lab whose humidity is between 40 to 60% RH. and temperature is between 20 to 25° C. All samples are preconditioned for at least 24 hours in that lab prior to testing. Untreated control white cotton fabric is prepared from new, 100% cotton, woven, white bed sheets, which are de-sized by 3 rounds of laundering 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), then cut to yield fabric pieces approximately 10 cm×10 cm in size. Treated test fabric is the same as the untreated control fabric plus the addition of the treatment being tested, which is applied to the fabric in accordance with the manufacturer's instructions, after the de-sizing steps.
On a flat, level hard surface (e.g. benchtop) is placed a fresh square of a paper towel at least 10 cm×10 cm in size, and on top of that is placed a square of the prepared fabric. A 300 μL drop of liquid is then dispensed onto the fabric surface from a calibrated pipettor. The drop is DI water when measuring water repellency or it is Canola Oil when measuring oil repellency—. The process of absorption of the liquid drop is visually monitored using a video camera such as a—Webcam Pro 9000 (Logitech, Silicon Valley, Calif., USA), integrated with a laptop computer, and displaying either an electronic timestamp or a stopwatch timer within the field of view, which counts the time elapsed in seconds. The imaging conditions are set up such that the margins of the drop and the fabric surface are both clearly visible and simultaneously in focus, with the viewing angle being from directly above. Nine drops are administered per fabric square, with each drop placed at a different location separate from all adjacent drops.
The recorded video is used to determine the time—at drop addition and the time—at drop absorption. For each drop, the time differential between those two time points is calculated and recorded. The time at drop addition is defined as being the earliest time point at which a portion of the drop is observed making contact with the surface of the fabric. The time at drop absorption is defined as being the earliest time point at which no portion of the drop is observed rising above the surface of the fabric. After 60 minutes, the video capture is terminated regardless of any remaining drops left unabsorbed. Such drops are recorded as having a time differential of 60 mins. The Time to Wick value for a given liquid on fabric is the average of the time differentials recorded for 9 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
Nanoemulsions were diluted with DI water to a concentration of 1% prior to making particle size measurements. The particle size measurements are made via dynamic light scattering on a model 3D-DLS spectrometer instrument (LS Instruments, Switzerland). The software accompanying the instrument (version 6.3, LS Instruments, Switzerland) is used to control the spectrometer to acquire data and conduct particle size analysis in dynamic light scattering mode. The instrument is set with the following conditions: Wavelength=632 nm (HeNe laser), scattering angle=90°, Temperature=297 Kelvin (measured by the instrument with sample placed in water bath and equilibrated for 10 minutes), Integration Time Tint=2 min, Count rate set between 100-250 kcps (attenuating the laser power), Lag time set between 0.7 microseconds to 50 seconds. All measurements were taken in autocorrelation mode. All data are reported as the second-order Cumulant fit to the autocorrelation function. The nanoemulsion's particle size is reported as the average diameter value measured, when calculated on a volume-weighted basis. A nanoemulsion whose particle size is less than 200 nm is defined as being a nanoemulsion.
Technical Drying Time Test Method
Switches of human hair, which are of straight low-lift medium brown Caucasian hair, approximately 20 cm long and having approximately 4 g of hair per switch, are obtained from International Hair Importers & Products (IHIP) (White Plains, N.Y., USA) for use in the Hair Drying Time Test. Use three switches of hair per treatment and per control. To prepare the hair, measure and record the initial dry weight of each hair switch, then wash each switch using the following shampoo and instructions. Hang the switches on a rod above a sink, and wet the hair with 38° C. DI water until saturated. Squeeze out excess water and apply the specified shampoo, at a dosage of 0.1 g shampoo per 1 g hair (dry wt). Apply half the total amount of shampoo on one side of the switch and rest on the other side. Massage the hair switches by hand for 60 seconds to create lather throughout the switch. Rinse thoroughly with 38° C. DI water running at 4 to 6 L/min for at least 2 minutes (1 min per side). Use hand manipulation to squeeze out the excess water. Up to 35 g of hair can be shampooed simultaneously. Each ingredient in the shampoo is listed below at its final concentration in percent by weight:

The remaining steps in the hair dying time test method are conducted in an air conditioned room having a temperature of 20 to 25° C., and a relative humidity of 40 to 60% RH, and are conducted in immediate succession without any delays or pauses between steps. Apply the treatment product being tested onto just one hair switch at a time, using switches prepared and shampooed as specified above. Prior to applying the treatment, ensure that the hair switch is thoroughly saturated with 38° C. DI water but is not dripping. Place the switch in a plastic weighing-boat dish approximately 13 cm×13 cm, and dose the wet hair with 1 g of the treatment solution being tested per 4 g of hair dry weight. Apply the treatment solution homogenously along the length of the hair. Massage the treatment solution into the hair switch in the dish for 3 minutes with hand manipulation, ensuring that all the hair fibers are exposed to the solution. The switch is then subjected to multiple cycles of blow drying and weighing, where the duration of blow drying and the subsequent switch weight are recorded for each cycle, and are compared to the switch's initial dry weight. Hang the hair switch vertically and commence blow drying while the hair is still thoroughly saturated with water and treatment solution. Blow dry the hair switch using a Sunbeam 1600 Watt hand-held electric hair dryer with diffuser nozzle adapter, with the heat level selection set on High, (Sunbeam Corporation Limited, Botany, Australia), and positioned 7 cm away from the hair. After 3 minutes of blow drying (1.5 mins per side), weigh the hair switch and record the weight. Press the hair switch gently between two kitchen paper towels for 2 seconds and reweigh. Repeatedly blow dry and reweigh the hair again using drying time increments of 30 seconds for each cycle. When the switch weight approaches its initial dry weight, reduce the drying time increments to 20 seconds for each subsequent cycle, and continue the drying and weighing cycles until the hair switch returns to its initial dry weight. The switch's total hair drying time is determined by summing all of the drying times that were required to return the hair to its initial dry weight. This cumulative value is the switch's Hair Drying Time. The hair drying times obtained from the three replicate switches in each treatment are averaged to determine the mean hair drying time for the treatment. To determine the effect of the treatment on hair drying time, the mean hair drying time for the treatment is compared to the mean hair drying time obtained from 3 control switches, which were each dosed with 1 g of DI water instead of 1 g of treatment solution.
The above Technical Dry Time Test Method is also relevant to skin.
Contact Angle Test Method
The static contact angle of a nanoemulsion is determined by measuring a sessile droplet of water placed on a nanoemulsion-coated surface, as measured via an optical profile image of the droplet. The surface is prepared using 2.5 cm×2.5 cm sized silica wafers (J#19777), as available from Silicon Valley Microelectronics Inc. (SVM), (Santa Clara, Calif., USA). Clean the wafers by rinsing with DI water followed by further rinses with ethanol and then with acetone, ensuring that both the organic solvents are of a high purity grade such as that suitable for use in LC-MS analyses. Expose the wafers to ozone for 15 minutes, by placing a cleaned wafer into a specimen chamber attached to an ozone generator such as the UV/Ozone Pro CleanerTM (manufactured by Bioforce Nanoscience, Ames, Iowa, USA). The nanoemulsion to be tested is then spin-coated onto the cleaned and ozonated wafers. To achieve this coating, prepare the emulsion to be tested at a concentration of 500 ppm in DI water. Dispense 1600 μL of the nanoemulsion onto a silica wafer, wait 1 min then spin the wafer at 2000 rpm for 30 seconds in a spin coater instrument, such as the WS-400B-6NPP/Lite/AS2 (manufactured by Laurell Technology Corporation, North Wales, Pa., USA). The spin-coated wafer is the then allowed to cure for 24 hours at room temp or in an 80° C. oven for 1 hour. With the wafer at room temperature, use a contact angle goniometer such as the FTA 200 manufactured by First Ten Angstroms, Inc, Portsmouth, Va., USA), to measure the static contact angle of a sessile 10 μL drop of DI water placed onto the coated surface of the silica wafer. Prepare and measure 3 replicate spin-coated wafers for each nanoemulsion to be tested, and average the replicate contact angle results to obtain the contact angle for that nanoemulsion. The contact angle of the cleaned but uncoated silica wafer is 36°.
