Description

United States Patent Ofice 3,704,143 Patented Nov. 28, 1972 3,704,143 AEROSOL SPRAY POLISH Milton Nevitt, New Hyde Park, N.Y., assignor to Spray N Shine Incorporated, Wilmington, Del. No Drawing. Filed Oct. 14, 1971, Ser. No. 189,398 Int. Cl. C09g 1/10 U.S. Cl. 106-5 Claims ABSTRACT OF THE DISCLOSURE An aerosol spray shoe polish that is wax and silicone free. Ethyl cellulose is used as a base. A plasticizer is employed as is three solvents having different boiling points for providing high gloss, no wax build-up solubility of previous coatings, and dispersal of previously applied wax.

This invention relates to a wax-free and silicone-free polishing composition of the aerosol type especially adapted to be sprayed on shoes for both shining and polishing shoes and effectively waterproofing the lasts thereof.

In the past aerosol spray shoe polishes containing waxes such as carnauba wax and/ or silicones have been used. These polishes have had undesirable results from continued use because of wax build-up which causes an uneven and unsightly surface, and because heretofore the use of silicones has caused cracking of the leather of the last of the shoe on which it is sprayed. Further, in the case of shoe polishes it has been generally necessary to utilize a pigment as a part of the mixture to gain an effective and pleasing shine for shoes, which pigment requires spraying only in a protected or special area decreasing the desirability of the aerosol product due to possibility of staining. Further, when a pigmented product is utilized the shoe polish is adapted for use only on shoes of one specific color.

In the past, also various anti-blotching agents such as sodium dodecylbenzene sulfonate in a solution which must be wiped off to give a reasonable gloss of buffed to provide a shine.

The present invention overcomes the disadvantage of the prior shoe polish byusing in combination with ethylcellulose and diethyl phthalate as a plasticizer, a combination of three solvents of different boiling points which serve to assure an exceedingly high gloss with great depth and clarity yet which will not crack the the shoe leather, which leaves no wax build-up and which, in fact, smoothes out and utilizes any pigmented wax coating already on the shoe leather to re-pigment and color scuffed portions of the shoe.

The base used is preferably ethyl cellulose. Various other lacquer bases such as nitrocellulose have been tried but these bases have a tendency to color and stain rugs, carpets or clothing adjacent the shoes to be shined if such material is sprayed thereon. When using ethyl cellulose as a base, it will remain suitably plastic for at least the reasonable life of the shoes when as a plasticizer, diethyl phthalate is also employed. Other plasticizers have been tried but none eliminated the cracking of leather as well in the combination as did diethyl phthalate.

Besides the base and plasticizer, three solvents are used in the aerosol spray shoe polish to gain the desired results of this invention. As a base solvent, the substance sold under the trade name Cellulose Acetate which is ethylene glycol monoacetate is employed. As a solvent fully compatible with the ethyl cellulose, alcohol is employed which in the combination claimed immediately dissolves, spreads, disperses and evens out any carnauba Wax or the like which remains on the shoes from previous polishings and fills in pits, cracks and scutfs with this material.

As an ultra-fast acting solvent of very low boiling point which will at least partially dissolve prior lacquer coatings of most types which had been sprayed on the shoe to be polished there is used methylene chloride. This quickly evaporating solvent has been found to be useful in that almost immediately after spraying the uppermost layer of molecules evaporate leaving a sufficiently hard coating so the wearer may immediately utilize the shoes without fear of smudging the finish.

In the example of the composition of this invention, the following materials were co-mixed and packaged in an aerosol container at pressures ranging between 30 and 60 p.s.i.

THE EXAMPLE aerosol propellant and is preferably a mixture of Freon l2 and Freon 11 in the general proportion of 2:1.

Thus it can be seen that there has been disclosed a wax and silicon free spray polish for shoes and from the foregoing detailed description no unnecessary limitations should be understood therefrom as modifications will be obvious to those skilled in the art.

I claim:

1. An aerosol type wax and silicone free shoe polish for spraying onto a surface from a container in which said composition is retained under superatmospheric pressure, consisting esesntially of about 8-15% 'by weight of a cellulose acetate as a base, 2-4% of diethyl phthlate as a plasticizer, and three solvents of differing boiling points, said three solvents being 12-24% of ethylene glycol monoacetate, 6l1% alcohol, and 55-26% methylene chloride, there being from 15 to 20% of propellant in said container.

2. A polish as disclosed in claim 1, wherein the composition consists of 9.66% by Weight of said base.

3. A polish as disclosed in claim 1, wherein the composition consists of 2.94% by weight of said plasticizer.

4. A polish as disclosed in claim 1, wherein the composition consists of 16-80% by weight of ethylene glycol monoacetate, 8.40% by weight of alcohol, and 46.20% by weight of methylene chloride.

5. A polish as disclosed in claim 1, wherein the composition consists of 9.66% by weight of cellulose acetate, 2.94% by weight of diethyl phthlate, 16.80% by weight of ethylene glycol monoacetate, and 46.20% by weight of methylene chloride.
