Paint remover

A composition for paint or spot removal having a carrier, a chemical component selected from the group consisting of Tetraoxaundecane (TOU), N-Methyl-2-pyrrolidone (NMP), Diethylene Glycol Monobutyl Ether, Ethylene Glycol Phenyl Ether, Propylene Glycol Phenyl Ether, Dipropylene Glycol N-Butyl Ether, and a combination thereof, and a co-solvent. A method of using the composition to remove a stain or spot from a carpet or other non-porous or hard surface is provided.

FIELD OF THE INVENTION

The present invention relates to a chemical composition for use as a paint or spot remover and to a method of using the chemical composition.

BACKGROUND OF THE INVENTION

Today the most effective paint clean-up remover contains acetone. This compound is extremely flammable and causes flash fires very quickly. There is a need to find safer, less hazardous compounds that causes little to no harm to the consumers.

SUMMARY OF THE INVENTION

The present invention relates to a paint or spot remover composition.

In an embodiment of the invention, the composition comprises: a carrier, a chemical component selected from the group consisting of Tetraoxaundecane (TOU), N-Methyl-2-pyrrolidone (NMP), Diethylene Glycol Monobutyl Ether, Ethylene Glycol Phenyl Ether, Propylene Glycol Phenyl Ether, Dipropylene Glycol N-Butyl Ether, and a combination thereof, and a co-solvent.

In an embodiment of the invention, a method of using is provided. The method comprises applying a chemical composition comprising a carrier, a chemical component selected from the group consisting of Tetraoxaundecane (TOU), N-Methyl-2-pyrrolidone (NMP), Diethylene Glycol Monobutyl Ether, Ethylene Glycol Phenyl Ether, Propylene Glycol Phenyl Ether, Dipropylene Glycol N-Butyl Ether, and a combination thereof, and a co-solvent to a surface having a paint or spot applied thereon; and removing the paint or spot from the surface with the composition.

In an embodiment of the invention, the surface to which the composition is applied is of a carpet or other non-porous surface such as a hardwood floor, among others.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following description of the embodiments of the present invention is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. The following description is provided herein solely by way of example for purposes of providing an enabling disclosure of the invention, but does not limit the scope or substance of the invention.

In an embodiment of the invention, a composition for use a paint remover is provided. The composition of the present invention comprises a component selected from the group consisting of Tetraoxaundecane (TOU), N-Methyl-2-pyrrolidone (NMP), Diethylene Glycol Monobutyl Ether, Ethylene Glycol Phenyl Ether, Propylene Glycol Phenyl Ether, Dipropylene Glycol N-Butyl Ether, and a combination thereof. Preferably, the composition comprises Tetraoxaundecane (TOU). An example of Tetraoxaundecane (TOU) is 2,5,7,10-Tetraoxaundecane.

In an embodiment of the invention, the paint remover composition meets volatile organic compound (VOC) laws which require 3% or less for a spot remover, as set by the California Air Resources Board (CARB).

The composition of the present invention may further comprise potassium hydroxide which may act as an alkaline activator for faster penetration and to aid in release of the paint from the surface. The composition of the present invention, may further comprise a surfactant. For example, sodium xylene sulfonate (SXS), fatty soaps (oleates), ethoxylated alcohols, sulfonates, and sulfates may be used as surfactants.

Other types of chemical components may be present in the chemical formulation include, but are not limited to, oleic acid, methyl soyate, and combinations thereof.

The composition achieves paint removal without the use of acetone or substantially free of acetone. Thus, the composition of the present invention is safer and non-flammable as compared to compositions that contain acetone. The composition may be used to clean up paint splatter on carpet or other non-porous surfaces including, but not limited to, hardwood floors.

The composition of the present invention removes paint including, but not limited to, latex paint, acrylic paint, and a combination thereof. There is a synergistic effect among the components of the composition.

EXAMPLES

An example composition was prepared in accordance with the present invention having the following components:

Comparative Example 1

Blue latex paint (Valspar—Exterior Satin) was painted onto carpet and allowed to dry for 24 hours. Each formulation was sprayed 5 times and allowed to sit for 1 minute to penetrate the paint. The carpet was then scrubbed 10 times. Each formulation performance was given a rating of 1-5:

1=No Paint Removed

2=Little Paint Removed

3=Some Paint Removed

4=Most Paint Removed

5=All Paint Removed

The TOU paint remover was tested against other formulations to judge performance, and the results are set forth in Table 2.

Comparative Example 2

Red latex paint (Valspar—Satin) was painted onto carpet and allowed to dry for 24 hours. Each formulation was sprayed 5 times and allowed to sit for 1 minute to penetrate the paint. The carpet was then scrubbed 10 times. Each formulation's performance was given a rating of 1-5:

1=No Paint Removed

2=Little Paint Removed

3=Some Paint Removed

4=Most Paint Removed

5=All Paint Removed
