Description

TECHNICAL FIELD One aspect of the present invention relates to a furniture polish concentrate. Another aspect of the present invention relates to a furniture polish composition formulated from the above concentrate. The furniture polish concentrate of the present invention comprises dimethyl silicone and poly (dimethyl) -co-poly (methyl, oxygen-containing) having the structure described below.
It consists of a siloxane copolymer.

BACKGROUND ART Most furniture has a lacquer coating or "membrane" on some portion of its exterior. It is known to those skilled in the art that conventional furniture polishes form at least one additional film layer on top of the furniture lacquer coating or film. When a shear force is applied to an area along the surface of the furniture polish film layer, "smearing" of the polished furniture surface occurs.

The ability of a polished furniture surface (ie, a furniture polisher film layer) to return to its original appearance after rubbing, and the time required for the furniture polisher film layer to return to its original appearance, depends on the particular furniture polisher composition or Two factors or parameters that are becoming important for evaluating the performance of a formulation. So, here we use "dirty recovery (smea
The term "r recovery)" means not only the recovery rate, but also the ability to return to the original surface appearance if the surface coated furniture polish film becomes dirty.

There has been a long-felt need for a furniture polish composition or formulation with excellent soil recovery properties. However, commercially available silicone-containing furniture polishes, especially surface coatings obtained therefrom, typically lack this particular quality. In fact, many conventional dimethyl silicones tend to deposit films that exhibit "brozing."("Fogging" is a tendency to have stripes or streaks). In addition, dimethyl silicone, which is mostly liquid, tends to smear due to its liquid nature.

To reduce "fogging", a number of currently commercially available furniture polish formulators have replaced certain additives, such as waxes, oils and / or surfactants, with dimethyl silicone containing furniture polish formulations. Introduced to many of the things. However, the addition of such additives to furniture polish formulations often produces undesirable effects. For example,
The addition of wax to the polish formulations generally reduces the ability of the resulting polish film to exhibit full stain recovery, while the addition of oils and / or surfactants tends to exude more stains and is generally desirable. Absent.

Further, it is well known to those skilled in the art that certain light reflection properties of the applied polish film depend on physical properties such as film thickness and film viscosity.

Gloss depth, which is one of the light reflection characteristics, is related to, for example, the ability to reflect light on a polished lacquered furniture surface. In the case of the polished lacquered furniture surface described above, one particular gloss depth value is that most of the incident light passes through the polisher film, through the lacquer, and then onto the true or virtual substrate surface, For example, it is relatively more aesthetically pleasing to the eyes when reflected (or absorbed by) the actual grain surface of the furniture.

One specific gloss depth grade, high gloss (high shin
e) is known to occur when relatively much light is reflected from the surface of the polish film, while another particular depth of gloss quality, the rich appearance
Is known to occur when relatively little light is reflected from the surface.

Thus, the shearing force applied to the surface of the polish film tends to cause some sort of surface disorder called "smearing", which is the diffusion of reflected light and the exposure of the underlying substrate surface. And so on.

It is also well known to those skilled in the art that polish films that tend to exhibit lower gloss depths (ie, higher gloss) also tend to exhibit easier bleeding. Thus, gloss depth is considered as another particularly important performance parameter when expressing the identity of a polish film.

Because of its specific optical properties, a number of currently commercially available dimethyl silicones have been
Instead of film-forming components such as waxes and / or surfactants and / or oils, they have been utilized in furniture polish compositions. However, as noted above, the addition of waxes has an undesirable effect on overall stain recovery, and the addition of oils and / or surfactants has an undesirable effect on the appearance of stains.

Thus, commercial furniture polishes using conventional silicone-containing or conventional silicone-based liquids and certain conventional waxes, surfactants and / or certain oils,
Initially they tend to give some desirable surface appearance values, but in practice they eventually show various inherent disadvantages.

Surprisingly, when a particular furniture polish concentrate consists of a certain immiscible liquid, the furniture polish composition formulated from this concentrate provides the gloss depth quality achieved by the use of dimethyl silicone. Or the desired stain recovery properties described above, which have a value (giving a rich appearance), while exhibiting relatively more ruggedness (which is otherwise a film-forming polisher formulation consisting essentially of only liquid components) The present inventor has found that furniture surfaces can be provided with a membrane that retains some of them (given by the object).

Briefly, when the concentrate of the present invention is utilized in the manufacture of a furniture polish formulation, the present inventors provide a furniture polish concentrate capable of controlling at least three of the spot recovery as defined above. Has found. The three points are: (1) the rate of spot recovery, (2) the overall visibility of a particular spot, and (3) after rubbing, the spot exudate film recovers to its original state. It is about.

Accordingly, one object of the present invention is to provide furniture polish concentrates, furniture polish compositions, and other similar household products, wherein the polish composition exhibits improved stain recovery quality. is there.

It is another object of the present invention to provide furniture polish compositions and / or formulations having improved stain recovery properties that can be applied and removed with minimal effort, as well as having so-called "depth of gloss" properties. Is to provide.

These and other objects, features, and advantages of the present invention will become more readily apparent to those skilled in the art from the following detailed description.

SUMMARY OF THE INVENTION The present inventors have discovered that furniture polish formulations that provide membranes having these and other desirable properties can be readily prepared from the furniture polish concentrates of the present invention.

INDUSTRIAL APPLICABILITY The furniture polish concentrates of the present invention are generally used in film-forming polish compositions and / or formulations for final application to various surfaces in the home, especially furniture surfaces. It is specifically formulated for inclusion or addition. That is, the composition or formulation is typically used to deposit a liquid polish film on furniture and other similar household items and various other household surfaces. The concentrates of the present invention can be formulated into a wide variety of creams, dispersions, emulsions and / or suspensions. Additionally, the compositions and / or formulations can be placed in, or transported by, appropriately sized industrial or commercial containers. In this regard, it is preferred that certain formulations of the furniture polish concentrates of the present invention be readily prepared into a wide variety of commercially available containers such as suitably sized aerosol containers, bottles, screw top jars, and the like. Can be put in. In addition, the compositions can be combined with other products. For example, a furniture polish composition formulated from a concentrate of the present invention can be impregnated into a porous material [see, for example, Muoio US Pat.
No. 65,518].

While the invention may be embodied in various forms, some presently preferred embodiments are described in detail below. However, this description is merely to be considered as illustrative of the present invention, and the present invention is not limited in any way to the particular embodiments described.

As noted above, one aspect of the present invention relates to dimethyl silicone and poly-

The sum of "y" and "z" is 100 mole percent.

Preferably, "y" is from about 20 to about 55 mole percent, and more preferably, "y" is from about 20 to about 50 mole percent.

The siloxane copolymer has a specific gravity higher than that of dimethyl silicone. Preferably, the siloxane copolymer is at least 0.001 greater than the specific gravity of dimethyl silicone.
It has twice the specific gravity.

Further, the siloxane copolymer preferably has a relatively higher viscosity than dimethyl silicone.

More generally, with respect to the siloxane copolymer,
The compatibility of the concentrate with the dimethylsilicone component, and certain other desirable physical properties required to exhibit the desired stain recovery, are based on the “A ₁ ”, “A ₂ ” and / or “B” groups. This can be achieved when certain other oxygen containing groups and / or phenyl containing groups are included. A typical group is> C
= O; -O -; - OCH 3; -OCH 2 CH 2 -; - OCH 2 CH 2 CH 3; -
(C = O) -O-; phenyl; and combinations thereof. To determine what films provide excellent stain recovery properties, the present inventor has determined that siloxane copolymers can be used to affect certain physical properties of the siloxane copolymers thus prepared. I introduced some of the representative groups mentioned above. The physical properties of the siloxane copolymer include refractive index, viscosity, compatibility with furniture lacquer surfaces, and specific gravity for dimethyl silicone.

Further, in general, with respect to siloxane copolymers, the presence of a dimethylsiloxane moiety (ie, the “y” portion of the molecule) in the molecule is for two reasons: , And to improve wetting of the nitrocellulose substrate by the siloxane copolymer.

Throughout this patent application, we use the term "dimethyl silicone". Many dimethyl silicones currently commercially available, commonly referred to by those skilled in the art as "polydimethylsiloxane", are generally well known. In this regard, dimethyl silicones particularly suitable for the purposes of the present invention are disclosed, for example, in Holdsock et al., U.S. Pat. No. 3,576,779, and in particular Petrarch Systems of Bristol, Pennsylv.
"Petrarch Systems, published in 1987 by ania,
Silanes and silicones (PetrarchSystems, Silane and
Silicones), catalog pp. 258-265.

In a particularly preferred embodiment of the siloxane copolymer,
“B” is represented by the following structure.

Also, the "y" value in the structure shown above is between 20 and 50 mole percent.

As mentioned briefly above, another aspect or feature of the present invention relates to a furniture polish composition formulated from the furniture polish concentrate of the present invention. Yet another aspect of the invention is
An article of manufacture, such as a porous pad, comprising the furniture polish composition. Still other aspects or features of the present invention will become more readily apparent to those skilled in the art from a reading of the following description.

Most furniture has a lacquer layer or membrane on at least a portion of its outer surface. Such lacquer films typically have a refractive index between about 1.49 and 1.53. Generally, the refractive index of such a lacquer film is about 1.50.

The furniture polish concentrate of the present invention comprises two mutually immiscible film-forming liquids, a dimethyl silicone component and a poly (dimethyl) -co-poly (methyl, oxygen containing) siloxane component. The components are at room temperature (ie 25
(° C.). When the concentrate of the invention is introduced into a furniture polish composition or formulation, the two above-mentioned immiscible liquids form separate layers on the lacquered furniture surface. In particular, dimethyl silicone forms the top layer,
The poly (dimethyl) -co-poly (methyl, oxygen containing) siloxane forms an intermediate layer, and the furniture lacquer layer defines the true or "virtually" surface of the furniture. Therefore,
Poly (dimethyl) -co-poly (methyl, oxygen-containing) siloxane has a relatively higher specific gravity than dimethyl silicone. In particular, the specific gravity of dimethyl silicone is typically
It is in the range between 0.90 and 0.97.

The present inventors have discovered that furniture polish compositions having improved stain recovery can be readily formulated when certain conditions are present in each of the above-described mutually immiscible film-forming components. Briefly, the viscosity and refractive index values of the silicone and siloxane layers are of primary importance.

For example, the inventor has observed that by reducing the viscosity of the dimethyl silicone present on the surface as the top layer, the rate of stain recovery can be increased. further. The inventors have observed that the spot recovery rate can be increased by specifically selecting a particular siloxane copolymer such that the siloxane copolymer in the intermediate layer is relatively incompatible with the uppermost dimethyl silicone layer. did. That is, dimethyl silicone and siloxane copolymers that are both liquid at room temperature naturally tend to separate easily into separate layers. As a result of the above tendency, the polished film relatively quickly recovers to its layer structure after being stained or soiled.

The inventor has also observed that when the dimethyl silicone component and the siloxane copolymer component have similar refractive indices, the visibility of certain spots tends to be significantly reduced. The mixing during the soiling of the two separate membrane layers, the silicone layer and the siloxane layer,
There is a tendency to produce a dispersion of these two components, which diffusely reflects incident light from the interface of the dispersed components.
(It has been observed that furniture polish formulations incorporating additives such as waxes, oils, and / or organic surfactants have a typical tendency to have high refractive index values).
Because the silicone and siloxane components of the concentrate of the present invention have similar refractive indices, only a relatively small amount of the incident light is reflected from the interface between the two components.

Between the siloxane copolymer and dimethylsiloxane, such that the siloxane copolymer has a higher viscosity value, such that the viscosity difference value is maximized,
The inventors have also observed that the visibility of certain stains can be controlled. Thereby, it becomes relatively more difficult for the siloxane copolymer to be dislodged from the true or virtual substrate surface during smearing, especially during "severe" smearing.
(The term "severe" stain refers to a shear force or other surface disturbance significantly greater than typical). In other words, the exposure of the true or virtual substrate surface is more pronounced due to the optical properties of the lacquer, which typically has a refractive index different from the refractive index value of the furniture polish film, of about 1.50. Can easily occur sufficiently.

The refractive index values referred to herein were measured using an Atsube-type refractometer known by those skilled in the art. The refractometer measures the refractive index of a liquid such as the silicone and / or siloxane components. Furthermore, each measurement was based on the so-called sodium "D" line with a wavelength of 5893 nanometers.

The present inventors have discovered that by maintaining certain physical properties of the dimethyl silicone and siloxane copolymer liquid components, the concentrates of the present invention can be formulated into a polish composition having highly desirable stain recovery properties. .

In particular, the dimethyl silicone of the surface layer typically has a viscosity of about 5 to about 1,000 centipoise (cp). Preferably, the dimethyl silicone has a viscosity of about 100 cp or less, more preferably about 50 cp or less.

The term "poise" is the so-called "cgs" unit of viscosity, one poise is equal to 100 centipoise (cp); "Stokes" is the so-called "cgs" unit of kinematic viscosity, and one stoke is 100 centistokes (cstks). It is well known to those skilled in the art that the so-called "cgs" unit of density is expressed in g / cm ³ ; the viscosity value is equal to the product of the kinematic viscosity and the density value. That is, the viscosity value expressed in cgs units is obtained by multiplying the kinematic viscosity value expressed in cgs units by the density value expressed in cgs units.

On the other hand, the above-mentioned siloxane as the intermediate layer is typically 10
It has a viscosity of 0 cp and 5,000 cp. Preferably, the siloxane is between 400 and 4,000 cp, more preferably 2,500 cp
With a viscosity of between 3,000 cp.

As mentioned above, the intermediate layer preferably has a relatively greater viscosity than the surface layer.

Also, as mentioned above, another physical property that is important to maintain within certain control limits is the refractive index of each of the liquid dimethyl silicone layer and the liquid siloxane copolymer layer.

The liquid dimethyl silicone layer typically has a thickness of about 1.39 and about
With a refractive index between 140 and 140, the liquid siloxane copolymer layer typically has a refractive index between about 1.42 and about 1.46. Preferably, the siloxane copolymer has a refractive index from about 1.43 to about 1.45.

Typically, the furniture polish concentrate of the present invention comprises the furniture polish composition or the composition in an amount ranging from about 0.5 to about 50% by weight, based on the total weight of the particular composition (excluding the propellant). For use in formulations, concentrations of about 1 to about 10% by weight are preferred, with concentrations of about 1 to about 5% by weight being more preferred.

The concentration of the particular furniture polish concentrate used in the particular composition is not critical. In fact, those skilled in the art will appreciate that the amount of a particular concentrate will generally be affected by the relative proportions of certain other ingredients contained in the particular composition.

The above is also true for each of the other components utilized in formulating the various compositions that are examples of the present invention. That is, the concentrations of the other components, which will be described in more detail below, are not critical and are merely indicative of a preferred embodiment of the present invention.

The choice of optional ingredients for incorporation into any one or all layers of the polish film is dictated by the relative need of the layer for additives such as emulsifiers, especially to produce the desired film. . The emulsifier additive has, for example, its ability to form an emulsion, its inherent ability to reduce incompatibility between the surface and the underlying film beyond desirable limits, its overall viscosity, refractive index, specific gravity relative to the layer's specific gravity. Selected based on criteria such as effectiveness. At this time, the added emulsifier or surfactant is present in the liquid dimethyl silicone layer, or in the liquid siloxane copolymer layer, or in both layers, or at the interface between the two layers. It is contemplated that it can be in another layer, such as a layer. In any event, it is preferred to minimize all added amounts of emulsifier so as to minimize the possibility of experiencing undesirable effects during blotting.

More specifically, the polish compositions of the present invention can be oil-in-water (i.e., so-called "water-out") emulsions or water-in-oil (i.e., "oil-out") emulsions. One skilled in the art can readily select an appropriate surfactant (or emulsifier) or combination of surfactants (emulsifiers) to create the desired type of emulsion.

As will be appreciated by those skilled in the art, the term "emulsion" refers to two or more mutually immiscible, held in suspension by a small percentage of a substance called an emulsifier (or surfactant). It is generally accepted to mean a stable mixture of the following liquids: Furthermore, all emulsions are characterized by a continuous phase and a discontinuous phase dispersed in the continuous phase.

The siloxane copolymer component of the furniture polish concentrate of the present invention functions as an emulsifier. As a result, the furniture polish composition of the present invention can be formulated as an emulsion using only the furniture polish concentrate of the present invention. However, for various reasons, one of ordinary skill in the art may desire to incorporate certain other emulsifiers or surfactants into the furniture polish composition to achieve certain desired results. In fact, some of the following examples, which are illustrative of the present invention, do not include certain optional surfactants to illustrate the so-called "best mode" of the present invention.

More specifically, in formulating the various emulsions and polish compositions of the present invention, the following various solvents and optional surfactants are those conventionally used in furniture polish compositions. As far as the formulation of the furniture polish composition of the present invention is concerned, the only critical component is the furniture polish concentrate of the present invention.

In accordance with the principles of the present invention, suitable solvents generally include water and traditional hydrocarbon solvents described in detail below. However, as will be appreciated by those skilled in the art, when the "L" structure of the siloxane copolymer is -COO-, care has been taken to control the chemistry (such as pH) of the other components. Otherwise, water would not be an acceptable solvent, as undesirable hydrolysis would occur.

Thus, in general, when the “L” structure is —O—, traditional hydrocarbon solvents will typically, and if desired, be formulated in the furniture polish formulations of the present invention. Used for As is well known to those skilled in the art, solvents are typically utilized in conventional polish compositions to remove solvent-soluble residues from the substrate surface. Thus, for optimal results, the solvent used in making the emulsion polish compositions of the present invention should be sufficiently volatile to dry quickly after the composition has been applied to the substrate surface. And must not be so volatile that the composition dries prior to spreading as desired on the substrate surface (to provide the desired film).

Accordingly, certain solvents that are considered particularly useful according to the principles of the present invention are the so-called "cowlie butanols".
Values from about 20 to about 50, with a boiling range of about 60
C. to about 210.degree. C., preferably about 95.degree. C. to about 150.degree.

Various commercially available isoparaffinic hydrocarbon solvents, such as those sold by Exxon Corporation under the brand "Isopearl" and those sold by Dhillips Petroleum Corporation under the brand "Salt Rolls" Is currently preferred because it is virtually odorless.

In accordance with the principles of the present invention, other suitable hydrocarbon solvents include hexane, heptane and so-called "stodda"
rd) "solvent.

Further, various of the above hydrocarbon solvents can be used alone or in combination.

The hydrocarbon solvent used can be present in an amount from about 0.15 to about 90 weight percent, based on the total weight of the emulsified polish composition (excluding the propellant, if present). However, preferably, the hydrocarbon solvent is present in an amount of about 1.0 to about 25% by weight, more preferably about 5 to about 20% by weight.

As mentioned briefly above, all emulsions consist of a continuous phase and a discontinuous phase. The amount of surfactant (or emulsifier) present in the emulsion polish composition of the present invention is not critical, but in order to effectively disperse the discontinuous phase into the continuous phase, the emulsion polish composition of the present invention must be used. It will be appreciated that the article must include a predetermined amount of a surfactant (or emulsifier) or a combination thereof. As noted above, the present inventors have discovered that the siloxane copolymer component is fully acceptable to achieve the above results. However, other polish formulators (one skilled in the art) can introduce any surfactant as desired.

Thus, any surfactant (or emulsifier) useful for the purposes of the present invention is a conventional nonionic, cationic, and anionic surfactant (or emulsifier) commonly used in commercial polish for application to furniture surfaces. )including. The above conventional surfactants can be used alone or in combination.

Thus, in certain preferred embodiments of the present invention, certain conventional optional nonionic surfactants, and certain combinations thereof, are optionally utilized. This is because they provide some desirable emulsion stability. Therefore,
Any conventional nonionic surfactants (or emulsifiers) suitable for the purposes of the present invention are the so-called "sorbitan" esters of oleic acid and lauric acid, polyethoxylated sorbitan esters having up to 20 ethoxy units, monoglycerides of fatty-forming fatty acids And diglycerides, and mixtures thereof.

Another example of an optional, preferred, commercially available nonionic surfactant (or emulsifier) is certain "span" brand and "twin" brand emulsifiers, both of which are now available from ICI Americas, Inc. , "Monamide" brand emulsifiers (currently available from Mona Industries, Inc.). Specific examples of the above emulsifiers include "Span
Sorbitan monooleate sold by ICI Americas, Inc. under the "80" brand, IC under the "Span 20" brand
Includes sorbitan monolaurate sold by I Americas, Inc. and sorbitan monopalmitate sold by ICI Americas, Inc. in "Span 40" Fland.
Mixtures of the various optional surfactants (or emulsifiers) described above can also be used, if desired, in accordance with the principles of the present invention.

Accordingly, it is presently believed that the following conventional cationic surfactants or emulsifiers are suitable for the purposes of the present invention. These include certain quaternary ammonium compounds such as quaternary ammonium halides, quaternary ammonium sulfate, so-called "fatty" amines which are ethoxylated and have about 2 to about 10 moles of ethylene oxide, chloride salts of the above amines or Includes acetates and amines that are ethoxylated and have 2 moles or more of ethylene oxide. Various mixtures or combinations of any of the above surfactants (or emulsifiers) are available to one of skill in the art, if desired, in accordance with the principles of the present invention.

Any conventional anionic surfactants or emulsifiers suitable for the purposes of the present invention include certain sulfates (eg, sodium lauryl sulfate, sodium alkyl ether sulfate),
Includes sulfosuccinates with attached polyethylene glycol moieties, and alkylaryl sulfonates. Mixtures of any of the above surfactants (or emulsifiers) can be utilized, if desired, in accordance with the principles of the present invention.

As mentioned above, the desired surfactant (or emulsifier)
Can be present in the compositions of the present invention in an amount ranging from about 0 to about 10% by weight, based on the total weight of the emulsion polish composition (excluding the propellant, if present). , About 0.0 to about 1.0% by weight. Certain surfactants are significantly polar and it is known that such surfactants often harm the lacquer surface, so the suitability of (or its) specific surfactants to be applied to the lacquer surface Amount).

Certain emulsion polishing compositions of the present invention include:
As described above, for example, when the “L” structure of the siloxane copolymer is —O—, water can be included as a basic component of the emulsion. It has been observed that the presence of water in the emulsified polish composition of the present invention helps "leveling" the resulting film of the emulsified polish composition when applying the film to a substrate surface. In addition, the presence of water tends to remove water-soluble soil particles that may be present on the treated substrate surface. Generally, taking into account the active ingredient,
Water constitutes the balance of the water-containing emulsion polish composition, and thus the amount of water as a residue is about 2%, based on the total weight of the composition (excluding propellant, if present).
To about 99% by weight, with a concentration of about 66 to about 93% by weight being preferred.

As alluded to above, the most preferred emulsified polish compositions of the present invention contain no wax. However, in some situations, it may be desirable to utilize a relatively small amount of wax in a particular formulation. Thus, from about 0.05 to about 0.5% by weight of wax, based on the total weight of the emulsified polish composition, can be used in the furniture polish composition of the present invention, if desired. Conventional waxes suitable for the purposes of the present invention thus include, but are not limited to, synthetic waxes such as microwax, petroleum wax, and certain natural waxes such as so-called "candelilla" waxes and "carnauba" waxes. .

In addition, other well-known additives, including (but not limited to) preservatives such as fragrances and formaldehyde,
If desired, it can be added to the emulsion polish composition of the present invention.

Flavors are typically added, for example, to provide the desired fragrance. Conventional fragrances suitable for the purposes of the present invention are well known to those skilled in the art and therefore will not be described in detail here. The amount of perfume to include is present in an amount effective to provide the desired fragrance intensity. The amount of the fragrance is about 0,5 based on the total weight of the emulsion polish composition (excluding the propellant, if present).
It can be from 05 to about 1% by weight.

Preservatives, typically formaldehyde, are commonly used to slow or prevent unwanted bacterial activity in containers containing certain formulations of the emulsion polish compositions of the present invention. As will be appreciated by those skilled in the art, the presence of the preservative is to extend the shelf life of the emulsion polish composition product thus formulated. A variety of well-known conventional quaternary compounds can be further utilized for the above purpose.

Further, the emulsion polishing composition of the present invention,
For example, a variety of well-known conventional pressurized systems containing a suitable amount of a liquid or gaseous propellant can be utilized to apply directly to the substrate surface. In particular, the emulsion polish composition can be applied directly to the substrate surface using well-known spraying means such as conventional pump sprayers. In addition, the emulsion polish composition can be applied to the furniture surface using a polish cloth or other suitable means. In addition, the furniture polish composition can be incorporated into a product, such as an absorbent fabric, if desired. See, for example, U.S. Pat. No. 3,965,518 to Muoio.

Further, as indicated briefly above, the emulsion polish compositions of the present invention can be provided in aerosol form.
To prepare the aerosol form, the emulsion polish composition is typically introduced into a conventional aerosol container and then capped with an aerosol valve. Thereafter, an effective amount of a suitable conventional propellant is introduced into the aerosol container in a known manner so as to achieve the desired pressure on the container. Thus, the propellant pressure must be sufficient to substantially completely displace the components contained in the aerosol container in the desired spray form through the aerosol valve. A wide variety of suitable conventional propellants that can be used include well-known liquefied hydrocarbon propellant gases such as isobutane, n-butane, propane, and various mixtures thereof. Examples of other propellants include, for example, carbon dioxide and / or nitrogen.

The aerosol form of the emulsion polish composition of the present invention typically comprises about 5% by weight of propellant, based on the total weight of the propellant-containing emulsion polish composition of the present invention.
In the range between 30% by weight. The weight percent or concentration of the desired propellant component is not critical and can vary widely depending on the desired end use.

Further, the detailed method of making the polish compositions of the present invention is not critical. As noted above, the order and / or mode of addition of the various emulsion polish composition components can therefore generally vary, and typically will affect the quality of the particular emulsion polish composition being formulated or manufactured. Do not give. Thus, various embodiments of the emulsion polish compositions of the present invention can be made using conventional techniques for forming water-in-oil and oil-in-water emulsion polish.

Embodiments of the so-called "wax-free" emulsion polish compositions of the present invention are made utilizing the known so-called "cold blending" method. For example, conventional cold blending processes suitable for the purposes of the present invention involve oil phase components (ie, for example, a suitable hydrocarbon solvent, siloxane copolymer,
The optional surfactant and, if present, the fragrance component) are charged to a suitably sized container, preferably equipped with a stirrer, and the oil phase components are then mixed until a homogeneous blend is obtained. Next, water and other aqueous phase components (eg, preservatives) are gradually added to the container while maintaining adequate agitation to produce the desired emulsion polish composition. When it is necessary to stabilize the water-containing emulsion polish composition thus formed, the emulsion polish composition can be prepared by applying a 60-80 psig pressure drop across the orifice to a 1.2 mm (3/64 inch) diameter. By passing through an orifice, the resulting composition can be homogenized.

As a component of the emulsion polish composition of the present invention, the wax should be combined with the oil phase component and the resulting mixture can be heated to a temperature sufficient to melt the wax and achieve a homogeneous mixture. After the addition of water and other components, the wax-containing composition can be cooled directly using a commercial cooling device, or can be cooled to room temperature (25 ° C.), and then can preferably be homogenized.

At room temperature (25 ° C.), 1.9 g of the siloxane copolymer, 5.6 g of dimethyl silicone, and 25.0 g of “Isopearl C” solvent were weighed to prepare each of the furniture polish formulations shown in the table.
Each of these ingredients was introduced into a 255 ounce (9 ounce) commercially available screw top glass jar and then stirred with a conventional laboratory stirrer at room temperature until a homogeneous mixture was obtained. Next, the above proportions of formaldehyde and water were weighed into a beaker and, while constantly stirring the contents of the jar,
The mixture was slowly added to the mixture contained in the jar to form a water-in-oil emulsion. Next, 80 g of the water-in-oil emulsion thus prepared was weighed and introduced into a conventional aerosol container having a capacity of 162. Then, replace the aerosol container with a commercial propellant

A propellant-containing formulation having a pressure of about 32 psig was obtained. The propellant used consisted of 34% by weight of propane, 26% by weight of isobutane and 40% by weight of n-butane. For aerosol containers, a suitable commercial spray button was chosen so that the propellant-containing furniture polish formulation could have similar spray characteristics to commercially available furniture polish formulations.

Formulation operation of each example in Table IV Each formulation shown in Table IV above was prepared as follows.
"Span 80" (trademark) surfactant 2 g, dimethyl silicone 22 g, micro wax 1.2 g, purified paraffin 0.6 g,
80 g of "Isopearl C" solvent is weighed into a 1000 stainless steel beaker, and the contents are melted at about 61 to 71 ° C. until the wax melts.
(About 150-160 ° F) to make each of the conventional furniture polish formulations shown in the table. While maintaining the high temperature, the contents of the stainless steel beaker were mixed to form a homogeneous mixture. Then, at room temperature, that is, about 20-24 ° C (about 68-75 ゜
F) water and formaldehyde ( "CH ₂ O") was introduced into a separate beaker and mixed until uniform. Once homogeneous, Note while maintaining a high temperature, with vigorous stirring at normal laboratory stirrer, gradually added to a stainless steel beaker contents aqueous CH ₂ O mixture to make a uniform water-in-oil emulsion. The resulting emulsion was cooled to about 23 ° C (74 ° F) using a conventional water bath.

Evaluation of Stain Properties of Various Formulations Ten test panels of about 14.6 cm × about 22.2 cm (about 53/4 inch × about 83/4 inch) were prepared. Each test panel
It consisted of a smooth black "FORMICA" plastic material coated with a normal high gloss nitrocellulose furniture finish. (Although the term "FORMICA" is used inappropriately as a core material with high pressure laminated sheets of melamine and phenolic plastics for surface decoration, insulation, adhesives for bonding laminated plastics to other surfaces, laminated plastics, though inappropriate It is sometimes used as a general term for flakeboard and industrial plastics that use various thermosetting resins in combination with various base materials for electrical, mechanical and chemical applications, but the correct use of "FORMICA" is `` FORMICA '' is American Cyanamid Company of Ci
Recognize the brand name of Formica Corporation, a subsidiary of ncinnati, Ohio).

Each of the ten test panels was coated twice with a corresponding one of ten different furniture polish formulations. (Ten different furniture polish formulations consist of Examples 1-8 of the present invention and Examples "D" and "E", respectively, which are representative of conventional furniture polish formulations). Thereafter, operations well known to those skilled in the art are performed. The water and "Isopearl C" solvent are effectively evaporated from the test panel to which each formulation was applied. (In particular, the preferred operation is to place test panels coated with each formulation into pre-formed wells of a larger conventional test panel to provide a polished area of about 46 cm x about 69 cm (18 inches x 27 inches). Is to insert).

As soon as the test panels to which each furniture polish formulation was applied no longer evaporate the water and the "Isopearl C" solvent (about 5 minutes after applying the furniture polish formulation), each test panel was removed. It was placed in a conventional stain measurement device. (The "9281B Measurment Platform" stain measurement device used here is the Kistler Instrument Company
of Amherst, New York).

Measurement of finger and knuckle spots A test panel coated with each furniture polish formulation was rubbed four times with the finger and knuckles at a downward pressure varying between about 0.15 Newtons and about 1.0 Newtons. (1
"Newton" is worth 0.2248 pounds).

Rubbing of each finger was about 1/2 inch (about 1.3 cm) wide, and rubbing of each finger joint was about 3/16 (about 5 mm) 1 inch wide.

The furniture polish formulation application test panels thus rubbed were then evaluated for initial visibility of the stain and for the visibility of the stain after allowing the film to stand for 20-26 hours.

The degree of staining was rated visually using the following 0 to 8 point scale.

 1 The first spot is a trace or very difficult to see.

 2 Very slight stain 3 Slight stain.

 Looks relatively easy than the "slight stain" of 43.

 5 Slight to moderate stain.

 6 Moderate stain. The membrane has not yet been compromised, but the spots are clearly visible.

7 Terrible stains. Part of the film becomes removed from the surface. 8 Extremely terrible staining. The film has been completely removed from the surface. Measuring method of stain recovery The measuring operation of the recoverability of only the transparent thin film is as follows.

Murakami, a commercially available goniometer, specially armed with a solenoid-operated swingarm
mi) The brand GP-1R was used. 1.9cm (3/4 inch) wide stain media (smear mediu)
m). The stain medium is 220 microns or 300 to 3
It consisted of multiple contacting parallel strands of a 25 micron diameter commercial monofilament wire. Each strand consisted of a stretched generally linear section and a single generally "C" -shaped section at one end of the linear strand. Each monofilament wire strand is
The generally linear strand portion was generally arranged such that the bent portion of the monofilament strand was on the surface of the test substrate while being substantially perpendicular to the test substrate.

Thus, each bent portion of the plurality of strands is arranged such that the bent portion of each filament is in contact with the substrate, such that the plurality of strands make substantially complete contact on the test substrate area where the plurality of strands are rubbed. I did it.

Each test substrate consisted of a 5.7 cm (2.25 inch) by 5.7 cm square, 3.2 mm (1/8 inch) thick piece of clear glass having a refractive index of about 1.50 to 1.52. In this operation, it is important that the lacquer and the glass have approximately equal refractive index values. In addition, each clear piece of glass was coated with 1.25 g of furniture lacquer containing high gloss nitrocellulose.
This lacquer contained about 21.3% by weight of non-volatile substances. The lacquer applied to the glass was gradually cured under the clockwork on a horizontal surface to give a smooth and uniform finish on the glass piece. The back side of each glass test slide was thus covered with black lacquer to remove reflection from that side. The lacquered side of each piece of glass had a refractive index between 1.50 and 1.53.

Each glass slide coated in this way was 0.10 mg before insertion into a 48 cm (19 inch) x 43 cm (17 inch) furniture panel.
Weighed on a conventional analytical balance that can be weighed up to. Thereafter, each slide-and-panel assembly was polished twice using a soft cloth with a corresponding one of the ten furniture polish compositions described above. To measure (by difference) the weight of each polish film deposited in this way,
The weight of each treated glass slide was determined on an analytical balance. In this way, the thickness of the polish film deposited was mathematically determined. Each treated test slide was inserted into the sample holder of the goniophotometer, and then the 15 ° incidence diametric rate of the test surface was measured directly. The solenoid drive arm was activated and the test membrane was rubbed. This smearing resulted in a decrease in the specular reflection of the test film. The specular reflectance of the film was monitored as a function of time to determine the percentage of initial reflection at 0.25 seconds and 158 seconds.
