FIELD OF INVENTION

This invention relates to a water in oil emulsion containing both natural and synthetic waxes together with a suspension agent(s), surfactant(s), polishing agents, and high purity aluminum oxide particles having a mean particle diameter of less than 300 nanometers and typically of less than 1.0 and preferably less than about 0.25 microns or micrometers which is equivalent to 250 nanometers, providing a composition that cleans and forms a high gloss protective finish on automobile exterior glass, metal, plastic and painted surfaces.

BACKGROUND OF INVENTION Description of the Prior Art

There are numerous wax products available on the market to protect and polish the painted body surfaces of an automobile and also various different ways of applying the same. The most recommended procedure is to wash and dry the painted surface, apply the protective finish to the clean dry surface, and then buff the surface. The applied wax remains as a protective finish throughout several subsequent washes but it is a time consuming labor intensive procedure.

A quick wax job is obtainable in an automatic or semiautomatic car-wash where a detergent is applied to the surface of the vehicle under high water pressure and/or using a water and detergent solution together with strips of absorbent material or sponges to remove the dirt. As part of the car-wash liquid wax may be sprayed onto the vehicle and allowed to drip dry or be dried using an air blower. The wax compositions used by professional car washes that are applied while the automobile painted surface is wet are immediately subjected to a blow dry step and are not buffed. Neither of the latter two wax compositions and procedures of applying the same provide long lasting satisfactory results.

Conventional commercial waxes and polishes typically contain a wax dispersed in water or dissolved in a solvent often together with abrasives for dry application to a painted surface of a automobile. The wax dries and is removed with hand or mechanical buffing machines requiring considerable labor and time.

Polishing compounds, especially those defined as cleaner waxes are generally formulated with abrasive materials such as aluminum oxide of larger than 1.0 micrometer particle size. When polishing a car's painted surface, the cleaner waxes remove contaminants; however, the application and removal of same typically leaves a clean but dull surface. At least a second step of waxing is required with a polishing compound which typically incorporates a high percentage of natural or synthetic waxes and a minimum amount or no abrasive material in order to achieve a coat of wax having a high gloss appearance.

SUMMARY OF THE INVENTION

DESCRIPTION OF THE PREFERRED EMBODIMENT

The instant invention is particularly directed to reducing the effort of providing a glossy finish on the painted exterior surface of a vehicle such as an automobile or the like by combining the step of applying a cleaner wax and a polishing wax in a single application. The exterior surface of the automobile is washed in a conventional manner using appropriate conventional cleaning agents such as detergents in the water and the surface is then rinsed using clean water. The surface is dried after rinsing and before the wax is applied thereto.

One preferred embodiment of the instant invention comprises a wax composition utilizing a selected amount of blended components and solvent for providing a cleaning action to the vehicle surface and leaving a residue of wax which upon buffing yields a high gloss surface.

One preferred wax composition comprises a water in oil emulsion containing a cationic carnauba wax micro emulsion, a silicone oil emulsified, alkyl quaternary ammonium montmorillonite, polyglycerol ester of oleic acid, aliphatic hydrocarbons, synthetic isoparaffinic hydrocarbons, water, anhydrous aluminum silicate, and high purity aluminum oxide preferably having a mean particle size of 25 micrometers or less.

More particularly, a preferred wax composition is composed of a water in oil emulsion having about 10 to 20 percent of soft or demineralized water, a cationic carnauba wax micro emulsion in an amount of about 10 to 40 percent by weight, an emulsified silicone oil comprising a blend of liquid dimethyl polysiloxanes in an amount of from about 8 to 15 percent by weight, an alkyl quaternary ammonium montmorillonite in an amount of from about 1 to 3 percent by weight, an emulsifying agent such as a polyglycerol ester of oleic acid in an amount of from about 1 to 2 percent by weight, an aliphatic hydrocarbon solvent in an amount of about 25 to 40 percent by weight, a synthetic isoparaffinic hydrocarbon solvent such as ISOPAR E, and/or ISOPAR G having a slightly higher evaporation rate as an isoparaf finic solvent in an amount of from about 1 to 5 percent by weight, an anhydrous aluminum silicate in an amount of from about 1 to 5 percent by weight, and a high purity aluminum oxide in an amount of from about 1 to 3 percent by weight having a particle size of about 20 micrometers or less. A corrosion inhibitor is optionally added to inhibit corrosion. One of more fragrances can be optionally added in an amount of from about 0.20 to 0.40 percent by weight. It is recommended as an option to add a biocide such as DANTOGARD or SURCIDE in an amount up to 1 percent by weight of the total composition.

The resulting composition is a light brown liquid emulsion having solid contents of about 18 to 20 percent by weight. Application to a painted surface or other surface to be treated applied as a liquid or semi-solid paste results in an easy wiping and removal of excess product from the surface resulting in a glossy surface without streaks. A preferred method of application is applying with a sponge onto the dry surface whereby upon drying the surface is then buffed with a cloth, sponge, and/or other absorbent material to dry and simultaneously buff the same. The oil based composition provides a composition capable of cleaning and polishing in a single step.

The water in oil emulsion of the present invention forms at least two phases. The organic phase containing the wax product constitutes from about 80 to about 90% by weight of the total composition and the water phase constitutes the remaining portion of the total composition of about 10% to about 20% by weight. An emulsifier which may also be a surfactant stabilizes the emulsion preventing separation into separate phases. Both the aqueous phase and/or the solvent phase may include thickening agents, emulsifiers, surfactants, suspension agents, colorants, fragrances, and preservatives.

The water in oil emulsion of the present invention contain at least one emulsifier comprising an emulsifying agent of surfactants which is compatible in the predominantly aliphatic hydrocarbon mixture phase. A preferred emulsifier is polyglycerol ester of oleic acid. It is contemplated that other suitable emulsifiers may be selected from the group comprising sorbitan polyoxyethylene, sorbitan sesquioleate, sorbitan trioleate, and polyoxyethylene trioleate. The amount of emulsifier can vary. It is recommended that the least amount of emulsifier be used to provide an effective amount capable of maintaining a stable emulsion.

A long chain fatty alcohol provides a nonionic surfactant which includes cetyl, stearyl alcohol, ethoxylated fatty alcohol, cetyl palmitate, cetyl myristate, polyethylene glycol stearate, glyceryl monostearate, monolactate, monooleates, tallow triglycerides and ethoxylated esters. Polyoxyethylene sorbitan monooleate, alkyl glucosinates, ethoxylated cetyl alcohol, ethoxylated stearyl alcohol, and polyoxyethylene nonylphenol represent suitable ethoxylated esters.

The concentration of the emulsifier is added in an amount of from 0.1 to 2% by weight, more preferably from about 0.5 to 2% by weight, and more preferably in an amount of from about 0.75 to about 1.51 by weight. One preferred embodiment utilizes a concentration of 1.0 percent by weight.

The polish comprises a water in oil emulsion. The minor component being water and the major component is a combination of an aliphatic hydrocarbon solvent and a wax product including additives thereto. The ratio of water to the combination of solvent and wax product is in a ratio of about 1:4 to about a 1:9 whereby the value of 1 represents the water. Typically the water used in the formulation is soft or demineralized water.

Solvents useful in the formulation are predominately aliphatic hydrocarbon solvents and other light distillates. For instance, hydrocarbons containing up to 100 percent aliphatic hydrocarbons are most preferable and hydrocarbons containing less than 1 percent aromatic content are deemed very desirable. Also useful are solvents typically containing from about 10 to 90 percent aliphatic hydrocarbons. Solvents deemed suitable which contain less than 10% aromatic hydrocarbons include odorless mineral spirits, Stoddard solvent, and mixed alkanes that have a flash point of about 40° C. Another useful light distillate is CALUMET 420-460 (LVP-100). The solvent concentration can vary from about 251 to about 45% by weight of the final formulation. As shown in Example 1 the odorless mineral spirits is utilized at about 39.8 percent by weight of the total composition. As shown in Example 2 replaces the odorless mineral spirits with a light distillate sold under the trade name of CALUMET 420-460 (LVP100), which is utilized at about 29.75 percent by weight of the total composition. LPA-170 may also be used instead of CALUMET 420-460 LPA-170 is available from Condea Vista Company. It is a high purity mixture of hydrotreated isoparaffins and naphthenics with very low levels of aromatics. The solvent is clear and contains low levels of normal paraffins resulting in a solvent having a higher solvent strength and lower freeze point than competitive low-aromatic solvents with equivalent boiling ranges. LPA 170 is composed of about 60% paraffinic, 40% naphthenic and only about 0.2% aromatic hydrocarbons and has a boiling point range of 415-450° F.

In addition to the aliphatic hydrocarbon, an organic solvent is added to the wax composition to aid in cleansing. Organic solvents useful in the present invention include isoparaffins, aliphatic hydrogen solvents, paraffinic solvents, paraffins, synthetic isoparaffinic solvents. One preferred organic solvent is sold under the trade name of ISOPAR E or ISOPAR G which are synthetically produced isoparaffinic solvent sold by ExxonMobil Chemical Company which exhibit a low surface tension and also aid in the spreadability of soluble components. The isoparaffinic solvents are highly aliphatic compounds containing a high percentage of isoparaffins. The organic solvents used in the present invention are typically considered high boiling solvents having a low vapor pressure typically less than 11.0 mm Hg at 20° C. and preferably 0.1 mm Hg or less at 20° C. Furthermore, the most preferred ISOPAR solvents reportedly have a vapor pressure of about 10 mm Hg at 38° C. and more preferably have a vapor pressure of about 4 mm Hg at 38° C. The evaporation rate is an important criteria in selection of the organic solvent. The high boiling solvent is added in an effective amount up to 25 percent by weight, more preferably in a range of from between 0.01 to 15.0 percent by weight, more preferably in a range of from 0.1 to 10.0 percent by weight, more preferably in a range of from between 1.0 to 8.0 percent by weight based on the total weight of the composition. One preferred embodiment described in Example 1 of the present invention includes about 5.0 percent by weight of ISOPAR E based on the total weight of the composition blend. Example 2 utilizes 15 percent by weight of ISOPAR G based on the total weight of the composition in view of the faster rate of evaporation of ISOPAR G. The MSDS sheets for the ISOPAR solvents E and G are hereby incorporated by reference.

The wax product can comprise a synthetic wax instead of, or in addition to, the natural waxes; however, the preferred embodiment utilizes both synthetic and natural waxes and more particularly a wax having a cationic charge whereby the wax provides a surface-active substance in which the active constituent is the positive ion. The combination of the wax or combination of waxes in the final composition comprise up to 40 percent, and more preferably from 0.001 to 30 percent, and more preferably from 1 to 25 percent, and more preferably from 4 to 22 percent of the total composition. As set forth in the examples one preferred embodiment contains about 20 percent by weight of a cationic microemulsion of natural wax (12-15′ solids) and 7 percent by weight synthetic wax based on the total weight of the composition.

Preferably the combination of solvent and wax product comprises at least 47% of the weight of the total composition.

One preferred wax component is a natural wax, more particularly a carnauba wax, specifically a cationic carnauba wax micro emulsion. It is contemplated that alternate plant waxes such as candelilla, orange-peel, montan, and/or japan wax could be utilized in the present invention as alternate wax components, preferably in a cationic micro emulsion.

It is contemplated that synthetic waxes such as polyethylene wax, polypropylene wax, polyamide wax, and combinations thereof can also be utilized in the instant invention.

The instant invention preferably utilizes at least one natural wax such as carnauba wax. The wax is provided as a micro emulsion, typically a cationic emulsion consisting of about 12-15 percent by weight wax. Of course the wax could be obtained dry and dispersed within the blend of components separately from the emulsion providing the same: functional qualities; however, it is more convenient to obtain the wax in the form of an emulsion from commercial vendors. The wax emulsion consisting of about 12-15% wax solids is added to the wax composition blend in an effective amount to form a thin film on a surface upon buffing. The natural wax solids portion of the emulsion is present in an amount ranging from 0.001 to 6.0 percent by weight, and more preferably in a range of from 0.01 to 1.0 percent by weight, and more preferably in a range of from between 0.01 and 0.1 percent by weight based on the total weight of the composition. In the micro emulsion form, the natural wax emulsion is present in an amount of to 50 percent by weight, and more preferably from 0.01 to 40 percent, more preferably from 0.1 to 35 percent by weight, more preferably from 1 to 30 percent, more preferably from 10 to 25 percent by weight based on the total weigh of the composition. One preferred embodiment uses 20 percent by weight of a 15′ carnauba emulsion which results in the composition containing 3% by weight of carnauba solids as the active ingredient.

A preferred embodiment of the present invention also utilizes a synthetic wax in an amount of from between 0.001 to 30 percent by weight, more preferably in an amount of from 10 between 0.01 to 25.0 percent by weight, more preferably in an amount of from between 0.1 to 20.0 percent, and more preferably in an amount of from between 5 to 15 percent based on the total weight of the composition. One preferred example utilizes 10 percent by weight of the synthetic wax (dimethyl polysiloxanes).

Preferably, a synthetic wax comprising a silicone oil or one or more of liquid dimethyl polysiloxanes is used in the present invention to aid in spreading and enhance the gloss of the product upon application. The dimethyl polysiloxanes is typically obtained commercially as a silicone oil which is added to the blend of other constituents and mixed together to form the final wax composition. Dimethyl polysiloxanes from Dow Corning sold under the trademark 200 FLUID or from General Electric sold under the trademark SF96 polydimethylsiloxane fluid.

Moreover, polishes use fluids from 50 to 60,000 centistokes viscosity. Lower viscosity fluids provide better leveling and adequate gloss; however, higher viscosity fluids are better for higher gloss and depth of color. High viscosity systems are better lubricants for high wax systems. However, lower viscosity fluids may exhibit poor rub out and leveling properties, or even bronzing. The high and low viscosity fluids can be blended to optimize the desired characteristics.

An effective amount of the dimethyl polysiloxanes or blend thereof comprising an effective amount of from 5% to 20% by weight can be used in the present invention and more particularly in a range of from 8.0 to about 15.0% by weight of the total composition. One preferred embodiment uses an effective amount of dimethyl polysiloxanes in an amount of about 13.5 percent by weight of the total composition.

Embodiments characterized by Examples 1-3 of the present invention utilize a blend containing 4.2 percent by weight of the total composition of silicone fluid having a 350 cst and 2 percent by weight of the total weight of the wax composition of fluid having a 100 cst in order to impart the desired leveling characteristics for the wax composition. About 0.8 percent by weight of the total composition is comprised of a silicone fluid having a 100,000 cst value to impart the desired gloss characteristics. The MSDS sheets of GE Silicone Fluids 350 cst, 100 cst and 100,000 cst are hereby incorporated by reference herein.

As set forth in Examples 1-3, General Electric silicone fluid sold under the brand name of SF1706 (aminosiloxane or aminofunctional polysiloxanes) is used in an amount of 1 percent by weight of the total weight of the wax composition. The reactive aminosiloxane fluids and/or resins extend the durability of the wax and act as a protectant. The MSDS sheets of GE Silicone Fluids SF 1706 is hereby incorporated by reference herein.

The aminosiloxane or aminofunctional SF1706, SF1550 and other such fluids are often characterized as amine functional fluids, however, they are actually curable polymers containing reactive alkoxy groups which upon hydrolyzation convert to silanol (OH) units. The silanol further react to form a cross-linked siloxane linkage (Si—O—Si) on the polish surface. These amine groups increase the bonding properties to the polish surface either through ionic attraction or chemical reaction. The ionic and/or chemical bond insures resistance to detergent wash-off or micro abrasion during use of the polished surface.

As set forth in Examples 1-3, General Electric silicone fluid sold under the brand name of SF1550 (MethylPhenyl Siloxane Fluid) is used in an amount of 1 percent by weight of the total weight of the wax composition to extend the durability of the wax and act as a protectant, as well as enhance the gloss and shine. The MSDS sheets of GE Silicone Fluids SF 1550 is hereby incorporated by reference herein.

The wax composition of the present invention utilizes a thickening agent which may also aid in the suspension of particles in the emulsion. A preferred thickening agent is alkyl quaternary ammonium montmorillonite, a type of clay, in an amount of from 0.1 to 4 percent by weight and more preferably from about 1 to about 3 percent by weight of the total composition. The alkyl quaternary ammonium montmorillonite functions as a dispersant or thixotrope commercially available as CLAYTONE AF thixotrope from E.C.C. America, Inc. and works particularly well with the cationic carnauba wax micro emulsion. One preferred embodiment utilizes about 2.2 percent by weight fo the total composition of alkyl quaternary ammonium montmorillonite.

Clay polishing agents useful in the invention include kaolin, surface treated kaolin, calcined kaolin, aluminum silicates and surface treated anhydrous aluminum silicates. The silicone fluids with anhydrous aluminum silicates. The nanoparticles of silicon, clay or alumina are used in the finish penetrate into cracks and pores in the substrate surface. The penetration reinforces the surface of the paint by sealing it against penetration by oxidizing elements and reduces its tendency to scratch. The silicate aids in providing impact resistance. Kaopolite treated anhydrous aluminum silicate is a polishing agent used in the instant composition. It is typically a clay which contains varying proportions of Al2O2 and SiO2 which may contain crystals or whiskers up to 1 centimeter long. A preferred embodiment contains from 0.01 to 20 percent by weight, more preferably from 0.1 to 15 percent by weight, more preferably from 0.5 to 10 percent by weight and most preferably from 1.0 to 5.0 percent by weight based on the total weight of the composition. A preferred embodiment as set forth in the examples contains 1.5 percent by weight of kaopolite treated anhydrous aluminum silicate based on the total weight of the composition.

A particularly important constituent is the use of nano particles of high purity aluminum oxide preferably having an average particle diameter of less than 300 nanometers and typically about 0.25 microns or micrometers to 250 nanometers or less that as measured using a Sedigraph 5100-MPD(D50) Sedigraph 5100 obtained from Micromeritics Instrument Corporation. The median particle diameter of the powder is 0.25 microns or 250 nanometers. The particle-size distribution, based on equivalent spherical diameter in microns, is such that about 80 percent of the powder is less than about 0.4 microns and about 20 percent of the powder is less than about 0.2 microns. The distribution can vary but it is preferred that all of the powder be less than 1.0 microns in size, and at least a majority of the powder be no greater than 25 microns in size. More particularly, a preferred embodiment of the present invention utilizes an aluminum oxide preferably having a mean particle size of less than 1.2 microns or 1,200 nanometers. More preferably, aluminum oxide particles in the nanometer range are desired such as those having a mean particle size of less than 1.0 micron, more preferably having a mean particle size of less than 0.8 microns, more preferably having a mean particle size of less than 0.6 microns, more preferably having a mean particle size of less than 0.4 microns, more preferably having a mean particle size of about 0.25 microns, and more preferably having a mean particle size of about 0.20 microns. In one preferred embodiment the particles range in mean particle size from about 0.20 to 0.25 micrometers or microns. The particles are defined as a high purity alumina grade RC-UFX MAR (no Magnesium oxide), and agglomerate free which was available from Reynolds Metals Company and later sold to Baikowski. Because most polishing compounds are generally formulated with aluminum oxide have particles sizes greater than 0.25 micrometers, polishing of a painted surface with same usually leaves a clean but dull surface requiring waxing with a high gloss wax to obtain a glossy surface. Because the instant invention utilizes aluminum oxide having nano particles, another abrasion is provided to clean the painted surface, yet the nanoparticles do not interfere with the waxes thereby leaving a high gloss wax surface produced in a one step by applying the wax and removing same by buffing.

Preferred embodiments contain aluminum oxide having a mean particle size of 300 nm or less is present in an amount of up to 10 percent by weight, more preferably from 0.001 to 8 percent by weight, from 0.01 to 6.0 percent by weight, more preferably from 0.1 to 5.0 percent by weight, and most preferably from 1 to 4 percent by weight based on the total weight of the composition. A preferred embodiment as set forth in example 1 contains 2.5 percent by weight of aluminum oxide having a mean particles size of 200 to 250 nanometers based on the total weight of the composition.

A hydrocarbon based corrosion inhibitor such as LUBEROS RP-3118 from Lube Ros, a division of Burlington Chemical in Burlington, N.C., comprises an oil soluble formulated blend for use in formulating oil and/or solvent based rust preventives forms a protective non-staining coating for short term use. The corrosion inhibitor also imparts rust preventive properties to formulations, and in low viscosity oil/solvent acts as a base with water insoluble lubricant additives such as esters or oleates. It also polishes, forms a protective non-staining coating for short term use. It comprises 10-20% nap oil (100-200) sus, 5-10% water insoluble additives and the balance mineral spirits.

It is anticipated that LUBEROS RP-3115 and 8555 are corrosion inhibitors comprising oil soluble blends which could be utilized as substitutes for the LUBEROS 3118 in the present invention.

Preferred embodiments contain a corrosion inhibitor in an amount of up to 10 percent by weight, more preferably from 0.001 to 8 percent by weight, from 0.01 to 6.0 percent by weight, more preferably from 0.1 to 5.0 percent by weight, and most preferably from 1 to 4 percent by weight based on the total weight of the composition. Preferred embodiment as set forth in examples 4 and 5 contains 1 percent by weight of the corrosion inhibitor LUBEROS RP 3118 based on the total weight of the composition.

A biocide, such as DANTOGARD (DMDM Hydantoin) or TROYSAN 395 is optionally used as a preservative in the product. The biocide is not a necessary component to provide a functional wax composition for use on wetted surfaces; however, the preservative provides a useful shelf life to the product. The biocide preservative is added in an effective amount to preserve the wax composition product and ranges from 0.01 to 2.0 percent by weight, and more preferably in a range of from 0.05 to 1.0 percent by weight, and more preferably in a range of from between 0.1 and 0.5 percent by weight based on the total weight of the composition.

Other preservatives such as polymethoxybicyclic oxazolidine may also be useful in the present invention. Another biocide which can be added as an option is SURCIDE P in an amount up to 1 percent or more preferably in an amount of about 0.4 percent by weight of the total composition.

Although not required, an effective amount of one or more fragrances, such as vanilla, bubble gum, orange, fruity bouquet and the like may be added to the instant invention to impart a desirable scent to the product. Preferably the fragrance is present in an amount of up to 2 percent by weight, and more preferably of from between 0.001 to 1.0 percent by weight, and more preferably of from between 0.01 to 0.5 percent by weight. One preferred embodiment contains about 0.4 percent by weight of fruity bouquet based on the total weight percent of the composition.

Dyes, fungicides, and/or colorants may also be added to the wax composition in an effective amounts of less than 1 percent by weight based on the total weight of the composition.

FIG. 3 shows a comparison of steel plates subjected to the same selected humidity for 140 hours with 3(a) showing a clean, bare steel panel no wax control, 3(b) showing a clean, bare steel including application of wax according to the composition of Example 3 with no corrosion inhibitor, and 3® showing a clean, bare steel plate including application of wax including a corrosion inhibitor according to the formula set forth in Examples 4 and 5 using high purity aluminum oxide having a mean particle size of less than 300 nanometers and preferably 200 to 250 nanometers or less.

It is contemplated that an ionic carnauba micro emulsion would also work in the formulations set forth in Examples 1-5 with the other ingredients remaining approximately the same.

The following formulations set forth in Table I utilize polishing alumina having an mean particles size ranging from 0.15 to 0.4 microns (150-400 nanometers).

The experimental results set forth in Table I, reveals that the cationic emulsifier and its positive charge is attracted to the negatively charged car surface which becomes slightly hydrophobic attracting the waxes and oils to the surface resulting in a sheeting action due to the quaternary cationic surfactant. The resulting wax formulation formulated with a cationic micro emulsion results in a higher buffing resistance and higher durability. The data set forth for formulations A-D in Table I show that when a cationic carnauba micro emulsion is replaced with an ionic carnauba micro emulsion less buffing resistance is observed. In addition, a more stable formulation was observed using the ionic micro emulsion.

The cleaning and polishing wax composition of the present invention imparts a good degree of hydrophobicity to the waxed surface which traditionally consists of a metal, glass, plastic, or painted surface. As a control reference, water was used to wet the surface of metal panels giving results of very low contact angles of from 10 to 15 degrees. As the hydrophobicity of the surface increases, the contact angles increase providing an indicator measuring the balling up of water droplets on the surface. Angles greater than 90 degrees are truly non-wetting. Advancing and receding angles were determined. The first trial results are reported as follows:

In accordance with a compositions of the present invention as set forth in Examples 4 or 5, the contact angle of water droplets were measured and the results recorded as shown in FIG. 4. Five panels were prepared by rinsing in mineral oil to remove any coatings. Five drops of the cleaning and polishing wax were applied to four of the panels and left to cure overnight. FIG. 4 shows that the contact angle of the control reference panel to be about 88 degrees. After 1 washing the contact angle of the waxed panel was about 112 degrees, after 5 washes about 114 degrees, after 10 washes about 106 degrees, and after 15 washes about 108 degrees indicating continued protection even after 15 washes.
